Functional and Technical Requirements for EC600 Sheet Forming Testing Machine

Dual power hydraulic mechanism: The edge pressing hydraulic cylinder and the main stretching cylinder are independently controlled and do not affect each other
Main stretching cylinder servo electro-hydraulic drive, adjustable stretching speed up to 3mm/S
The edge pressing hydraulic cylinder is servo driven by electro-hydraulic, with a high edge pressing speed of 3mm/s; It can achieve two modes of edge pressing function: stroke edge pressing and closed-loop edge pressing. Stroke edge pressing is a high-power shearing or pressing of the sample at a speed of 3mm/S, while closed-loop edge pressing is used to achieve CNC adjustable edge pressing force, and the two modes are easy to switch between
The closed-loop edge pressing system can edit the output curve of "X-axis stretching displacement - Y-axis edge pressing force", and automatically track the corresponding edge pressing force value of the output curve as the stretching displacement advances. The editing of the "X-axis stretching displacement - Y-axis edge pressure" curve is simple and convenient, with built-in curve fitting algorithm to ensure smooth curve and smooth and continuous output of edge pressure force
Generate a curve graph with stretching displacement as the X-axis and stretching force as the Y-axis, which is easy to save; The corresponding values of stretching displacement stretching force edge pressure stretching time can be exported and saved in an Excel spreadsheet
Dynamic balance of circumferential edge load: ensuring uniform distribution of edge load on the circumference, preventing material asymmetric sliding caused by uneven edge force, and improving the accuracy of deep drawing test results
The mold assembly type mechanism reduces the probability of mold assembly errors, facilitates disassembly, and ensures that the concentricity deviation of the convex and concave molds is less than 0.05mm
Tensile force acquisition method: disc and spoke pressure sensor (no need for oil pressure piston area conversion, reducing errors), easy to disassemble and calibrate
Output interface: ① USB connection to PC interface
Monitoring method: ① The host comes with a human-machine interface, which can independently monitor the experimental process. ② It can also be connected to a computer through a USB interface, controlled and collected through software, and the tensile displacement curve can be saved to a PC
Test shutdown method: ① Automatic shutdown: The sensor senses a rapid decrease in the tensile force of the die, and the yield limit of the plate is judged to automatically shut down. The shutdown can be based on the proportion of the decrease in tensile force, or the descent time can be set. ② Manual shutdown: If cracks are observed, stop immediately. ③ Large tensile displacement can be set to stop the machine
Reserved water-cooled ring installation interface for expanding the heating device of the edge pressing mold
The system is equipped with a buffer start brake protection device, ensuring smooth start and stop. It is designed to be environmentally friendly and energy-saving, with a high energy efficiency ratio
Stretch start signal output level signal interface, used to trigger optical measurement system, default GOM online measurement series
