Abstract:
Hydraulic stretch forming is a very important technology. Punch press has achieved multi-station automatic processing in the press area, which has greatly improved the efficiency. However, the main domestic stretching machine is single-stretching hydraulic machine at present. Compared with punch press, hydraulic stretching machines take less space and have better security, but they make less efficiency and have lower degree of automation. Hence, in order to take the advantage of hydraulic stretching machines and enhance the automation level, studies on multi-position automatic stretching machine occupies an important position. This paper proposes a design scheme of Six-station Automatic Hydraulic Stretching Machine (SAHSM) according to the practical production. The overall 3D structure of SAHSM is designed based on Solidworks to prove the theoretical possibility of the program. Then modal analysis is operated based on FEA of the key components of stretching machine module to improve reliability of the product and overcome the disadvantage of the traditional checking method, the first two-order modes are obtained to prove the impossibility of the resonance. At last, ADAMS-based virtual prototype is analyzed to demonstrate the feasibility and effectiveness of the SAHSM dynamic design proposed in this paper

Abstract:
The aim of the work is to develop technical solutions aimed at creating a high-performance roller briquette press. The results of previous studies and the experience of creating roller presses of various designs, evaluating their production and technological efficiency are summarized. It was established that the basis for the development of an improved press design should be based on principles that ensure its simplicity, decrease in metal consumption, size, ease of operation, as well as the ability to provide the required physical and mechanical properties and quality of briquettes. It is shown that these principles can be implemented in the process of modernization of roller presses created earlier at the Institute of Ferrous Metallurgy. The roll press can be modernized by using mechanical and hydraulic devices to protect the rolls from overloading, developing new effective ways of attaching bandages and drive elements, using modern monitoring and control devices to regulate the operation of the press. Expansion of technological capabilities of the press is provided by using devices for distribution and pre-compaction of the briquetted charge. The choice of a rational scheme of deformation and calibration of the working surfaces of the press rolls ensures the optimization of the energy and power parameters of briquetting. The paper formulates recommendations and requirements for the creation of an improved high-performance roller press for briquetting a wide range of small fractional raw materials. Proposed a fundamental solution to the layout of the press.

Abstract:
Nowadays, the process of metal forming in the machining industry and welding workshop is developing very rapidly especially in the plate bending process. The bending process is the formation of metals which generally use plates or rods of both ferrous and non-ferrous metal materials by bending, which in the bending process will cause stretching or stretching on the neutral plane axis along the bending area and produce a straight bend line. The use of appropriate technology machines has been widely used to increase productivity, efficiency, and effectiveness in the production process for community businesses, especially those in the regions. One of the appropriate technologies that might be applied in the bending process is a hydraulic jack press that is equipped with a press tool. Press tool is one type of product forming, cutting and bending tools from the basic material of sheet plates whose operations are using a press tool. The results of the design of press tool bending tool V have a length of 300 mm bending line, 33 mm bending width, 110 mm spring height, free step distance of 19 mm. The punch angle used is 85⁰ with the punch radius used is 1.5 mm while the die angle is 85⁰. The selected punch and die material is Steel AISI 1045 HV HR.

Abstract:
The multi-domain modeling and simulation of the precision high-speed punching press was carried out using the software SimulationX in this article. The key technical problems of the multi-domain modeling, such as the establishment of the sub-systems of mechanics with accurate structures and dimensions, improvement of modeling accuracy and simulation efficiency by dividing and dealing with components in group and import of the displacement-depended stamping forces on the stamping dies, have been resolved to establish the integral multi-domain model, which contains sub-systems of mechanics, hydraulic and servo driven of the complete punching press. Vibration quantity of the punching press was predicted through simulation, and validity of the multi-domain model was confirmed by experimental measurement. The vibration reduction in the punching press based on the topology optimization of the slider and design of rotational speed variation curve of the servo motor were investigated. The results show that through topology optimization, the mass of the slider could be decreased under the premise of guaranteeing the structural strength, by which the vibration quantity of the punching press can be decreased; rotational speed of the servo motor could be decreased during the stamping period by designing the rotational speed variation curve, which leads to a decrease in acceleration and vibration of the slider during that period, with which the forming precision can be guaranteed.

Abstract:
This paper describes the constructed mathematical model of the controlled object of the automated system for controlling the displacement volume of the manipulator pump. The change in pump displacement volume is performed in order to save energy by minimizing the fluid drain through the overflow valve. The use of the considered manipulator is intended in the process of automated supply of blanks to the working area of a press used in forging and hot stamping processes. The reactive forces acting on the moving parts of the mobility modules from the fixed parts of the manipulator are determined. Conversion of the useful power of the pump into the useful power of hydraulic motors is performed. This takes into account the losses using efficiency. An equation describing the mathematical model of the controlled object is obtained. This equation is represented in relative variables. The derivation of this equation and the determination of the reactive forces are made on the basis of the assumption that all transport degrees of freedom are translational. This limitation is caused by the peculiarities of the working area of the press used in technological processes of forging and hot forming of blanks. The working zone is a deep horizontal tunnel, the movement of the working object in which is possible only with translational degrees of freedom.

Abstract:
Recent Power On Demand approaches, realized by using speed and/or displacement variable pump units, led to a significant increase of energy efficiency on hydraulic forming presses. In this paper we follow up on this development by laying the focus on the energy management and storage design of such machinery. With a derived fluidtronical model, we compare five different topologies that supply and manage the power flow for a forming press with die cushion. Our evaluation criteria are: energy consumption, minimization of the infeed power, and qualitative costs. For a representative forming cycle, the losses occurring on each of the drivetrain components and the power electronics accessory are derived in detail. We expect that this research will lead to deeper investigation of more intelligent energy management systems that use multiple storages in an optimal way and further learn and adapt during operation.

Abstract:
The scientific paper proposes a method to analyze and optimize the drawing press and the deep drawing process with a virtual model. It focuses on hydraulic multi-point die cushions since they offer a wide range of possible adjustments and a high potential to increase production quality and efficiency. The operator can apply individual die cushion cylinder forces to the blankholder which enables the control of the forming process and manual die spotting can theoretically be reduced to a minimum. Utilizing the virtual model can improve the drawing press’ behavior and significantly reduce the set-up time for drawing presses during try-out of new tools or when tool sets are transferred to a different machine. The paper presents a system simulation model of a deep drawing press including its mechanics, hydraulics, and control. It serves as a basis for developing an advanced control system which improves system performance with potentially higher slide speeds, and therefore, a more efficient production. Another aspect in the paper is the development of a coupled simulation consisting of the machine model and a process model. This includes the elasto-static as well as the dynamic behavior of the drawing press and allows for simulations with the highest possible level of detail. The model was used to determine individual set forces for the die cushion cylinders which allowed for the production of sound quality parts without manual die spotting.

Abstract:
Ongoing research has been done to develop control methods based on the simulated loading paths input to the press machinery. This forms an open loop system where the characteristics of the Press hydraulic unit involved delivering the forming agents, i.e. the axial cylinders and valves, are neglected. This process approach leads to most experiments being done by simplifications which is time consuming and expensive, curbs the ability to have feedback control and restricts development of complex machinery response algorithms. Cylinder force control and controller design models have been researched widely such as PID and H∞ but less is known about their application to Tube Hydroforming (THF) process control which is relatively new. This paper focuses on modeling the THF process and developing a Real time PID controller to operate with a prototype model. The position of the cylinder is tracked and compared with reference provided from a database via a dynamic data exchange link showing that control could be achieved with a prototype. Position control with above approach results in efficient and concerted control merging the loading path design flexibility with machinery dynamic response.

Abstract:
Forging is an effective method for railway axle in order to ensure the inner quality, good microstructure and properties. Based on the disadvantage of current processing techniques for railway axle forging such as large machining allowance, low dimension accuracy, materials and energy consumption, a new precision high-speed forging forming process is proposed. The whole forging process of axle is divided into three steps, including chamfering, rounding and forming. Forming qualities of railway axle mainly depend on anvil structure and operational parameters during high-speed forging. Simulation model is established using finite element method by DEFORM. Focusing on the forging stage of the railway axles, the influences of anvil design have been numerically analyzed. By analyzing the stress-strain distribution and the forming precision with different anvil structures (flat anvil and arc anvil), a new arc anvil for axle forging is proposed. Arc anvil which we put forward is better than flat anvil both forming quality and properties. As for anvil edge shape design, it is effective to select a Per-form zone to obtain high strain at the center. Structure and main parameters are designed. Effect of anvil relative length, transition radius between Per-form zone and relative length, arc radius of arc anvil on forming quality is analyzed in term of surface defects and inner stress-strain distribution. While the radius of arc is 150mm and the central angle of the arc is 90°, the equivalent strain is greater which will be benefit for inner defects cogging. Transition radius between Per-form zone and relative length is 50mm, concave defects on the surface of forging is the smaller. With the increase of relative length, forging force increases. Taking the productivity and inner strain distribution into account, relative length is 240mm. The independent influence of each chosen major operational parameter, i.e, the rotation angle, the feed and the reduction on internal quality and dimensional precision, has been studied. Suitable operational parameters for ensuring internal quality and dimensional precision have been specified. As a result, the optimum combination of rotational angle and relative feed is clarified. Compared with stress-strain distribution and inner strain distribution under different reduction, 20% is taken to ensure better strain status and efficiency, rotation angle is 90°during chamfering. While the relative feed is 0.6, rotation angle is 45° during rounding, rounding precision will be higher. Ellipticity will be best and variance of radius will be small. Experiment research is performed in 10MN high-speed hydraulic press. Compared with the forming size precision, the experimental results verified the feasibility of the structure of arc anvil and the operational parameters.

Abstract:
The development of smart hydraulic press that allows rapid adaptation to high-volume variant production is a major challenge. Besides tool management, setting the control parameters, which can be considered as a correct press cycle, is an important part to achieve agile production. This paper presents a new approach to automatically generate a hydraulic press cycle where the important data of the production plan is known, such as the data or setting of the forming tool and the data of the product. In this case, RFID tracking system is used to read the tool/product data, which is input data for the mathematical algorithm for calculating the characteristic points of the hydraulic press cycle. The characteristic points are sent to the local PLC and stored as a matrix. The Beckhoff TwinCat platform is used for process control. Finally, a simple bending process is shown as a use case for concept verification.

Abstract:
Abstract Accurate simulation of metal casting press-forming process needs to consider mutual coupling effects in a number of different fields of physics subsystem. Hydraulic systems, control systems and mechanical systems are the most important subsystems among them. It is difficult to create various subsystems in detail in a single modeling tools, so co-simulation technology is used to take advantage of different tools to achieve the entire physical process of system-level simulation. The paper researched the co-simulation in the Abaqus software and the Matlab software based on FMI standard, considered fully the coupling effect between different systems, and simulated the metal casting press-forming process. The simulation results showed that co-simulation based on FMI standard can be well suited for multi-disciplinary co-simulation in complex mechanical model, and played a well-guiding role in the engineering design. The co-simulation would take more computation time than traditional simulation, but it can be achieved to research the integrated features of system and to reduce greatly experiments costs and prototype trial risks by using this technology.

Abstract:
Servo presses are recently introduced metal forming machinery and they are in many ways, a hybrid of mechanical and hydraulic presses. They are designed to combine the strengths of conventional mechanical and hydraulic presses, and at the same time to minimize their constraints. The advantages of servo presses in metal forming technology are discussed briefly. Advantages they offer in warm forming are discussed more in detail and demonstrated experimentally. By using the flexibility that the servo press offers, the effect of contact pressure on temperature change and surface roughness of aluminum and magnesium sheet is experimentally investigated. Non-isothermal warm forming is introduced and studied experimentally. Combined advantages of the non-isothermal approach and the servo motor controlled press are demonstrated by introducing a variable forming speed concept. As a result, 60% savings in cup drawing time is achieved experimentally. Measured temperature curves were used in FEA to determine heat transfer coefficients. Effect of the determined heat transfer coefficients on deep drawing was analyzed using FEA and good agreement were obtained between FEA predictions and experimental measurements.

Abstract:
In the last decade, press hardening has become a fully established technology in both science and industry for the production of ultra-high-strength structural components, especially in the automotive industry. Beside the improvement of car performance such as safety and lightweight design, the production process is also one focus of trends in technology development in the field of press hardening. This paper presents an overview about alternative approaches for optimized process chains of press hardening, also including pre- and post-processing in addition to the actual forming and quenching process. Investigations on direct contact heating technology show new prospects regarding fast and flexible austenitization of blanks at compact device dimensions. By applying high speed impact cutting (HSIC) for trimming of press hardened parts, an alternative technology is available to substitute the slow and energy-intensive laser trimming in today’s press hardening lines. Combined with stroke-to-stroke control based on measuring of process-relevant parameters, a readjustment of the production line is possible in order to produce each part with individual, optimal process parameters to realize zero defect production of property-graded press hardened components with constant high part quality. Significant research in the field of press hardening was carried out at Fraunhofer Institute for Machine Tools and Forming Technology IWU, in the hot forming model process chain which enables the running of experiments under conditions similar to industrial scales. All practical tests were prepared by design of experiments and assisted by thermo-mechanical FE simulations.

Abstract:
This paper presents a theoretical–experimental pressure analysis of a hydraulic press brake with synchronized cylinders. In this machine, the motion of each cylinder is controlled by independent variable-speed electrical motors. This design has many benefits over traditional solutions using hydraulic proportional valves, such as higher energetic efficiency, nonrequirement of a heat exchanger, lower oil-cleanliness requirement, and reduced audible noise. However, a critical characteristic of the press brake is the use of double acting cylinders with large rods controlled by a pump in a closed circuit. In the studied system a cap end area roughly eleven times greater than the rod end area is used. Furthermore, the synchronized hydraulic press brake operates in six stages with particular characteristics implying in different flow rate demands and pressure behaviors. Based on experimental results, the pressures in specific parts of the circuit are analyzed and critical operational conditions are identified. A simulation model using Hopsan is validated and used to propose a hydraulic circuit modification. The proposed solution eliminates the tendency for pump cavitation and pressure surges that occur during the press break operational cycle.

Abstract:
Servo actuated presses can provide maximum pressing force at any slide position in the same manner that hydraulic presses do, while offering several benefits in terms of precision, energy conversion efficiency and simplicity due to their lack of hydraulic circuitry and oil. Several press builders have developed electric-spindle actuated presses; however, issues relating to multi-axis architecture have been neglected. The present study proposes an innovative method of avoiding overconstrained architecture by implementing a kinematic mechanism that connects multiple servo axes to one slide. Servo axis design is developed by creating a dynamic model of a kinematic chain composed of a servo-motor, gearbox reducer and ball screw transmission. A study of a biaxial industrial servo press prototype with non-overconstrained architecture, currently under construction, is presented as proof of concept. It is shown that such a non-overconstrained multi-axis press can be constructed from commercially available components, achieving high energy efficiency at high load with relatively simple construction.
