Sheet metal forming testing machineEC600Functional technical requirements

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, maximum to3mm/S
Hydraulic cylinder servo electro-hydraulic drive for edge pressing, maximum edge pressing speed3mm/SIt can achieve two modes of stroke edge pressing and closed-loop edge pressing functions, with stroke edge pressing based on speed3mm/SMaximum power cutting or compression of the sample piece, 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 be edited“XAxial tensile displacement-YAxial compression edge force”Output curve, automatically track the corresponding edge pressure value of the output curve as the stretching displacement advances.“XAxial tensile displacement-YAxial compression edge force”Curve editing is simple and convenient, with built-in curve fitting algorithm to ensure smooth curves and smooth and continuous output of edge pressure
Generate from stretching displacementXAxis, tensile force isYThe curve graph of the axis is easy to save; stretching displacement-tensile force-blank holder force-The corresponding values for stretching time can be exportedexcelSave Table
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
Mold assembly type mechanism reduces the probability of mold assembly errors,Easy to disassemble, while ensuring that the concentricity deviation of the convex and concave molds is less than0.05mm
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:①USBconnectionPCinterface
Monitoring method:①The host comes with a human-machine interface, which can independently monitor the experimental process②It can also be done throughUSBThe interface is connected to the computer, and the tensile displacement curve is controlled and collected through software connection. The curve can be saved toPC
Test shutdown method:①Automatic shutdown: The sensor senses a rapid decrease in the tensile force of the die, and the yield limit of the sheet metal 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 set②Manual shutdown: If cracks are observed, immediately shut down the machine③The maximum stretching 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
