Hot forming testing machine for sheet metalHost function

1. Dual hydraulic power structure, with two independent systems for edge pressing power and stretching power, which can independently control the direction, speed, and thrust of motion without affecting each other

2. Edge pressing mechanism: an independent pair of piston type hydraulic cylinders apply edge pressing thrust; Both edge pressing force and return force, as well as edge pressing speed and return speed, can be individually set and controlled

3. Closed loop control of edge pressure, with edge pressure curve output function, pre-set multi-point edge pressure values, the system needs to have a built-in curve fitting algorithm to output smooth edge pressure and control the edge pressure mechanism to follow the curve to output edge pressure

4. Configure a dynamic edge pressing load balancing mechanism to ensure equal edge pressing force on the circumference

5. Optimizing the motor speed of the edge pressing system, with a linear proportional relationship between speed and thrust, to achieve noise reduction and energy-saving emission reduction effects;

6. There are two working modes: stroke edge pressing and closed-loop edge pressing. Long press and hold the "stroke edge pressing" button to advance the edge pressing mold5mm/sPress the edge at a certain speed, and release it to idle0.5mm/sThe 'closed-loop edge pressing'

7. Stretching mechanism: Independent piston hydraulic cylinder applies stretching thrust; The thrust and return force of the stretching cylinder, as well as the stretching speed and return speed, can be set separately; Optimization of motor speed, with a linear proportional relationship between speed and thrust, to achieve noise reduction, energy conservation, and emission reduction effects

8. The output signal of the tensile force direct load sensor does not require feedback from the oil chamber pressure sensor or conversion of piston area, and there is no theoretical error in the thrust resistance of the tensile cylinder

9. Stretching automatic shutdown mode: fixed load upper limit stretching shutdown, fixed stroke upper limit stretching shutdown, stretching yield limit proportional shutdown

10. Software system: remotely connect through the network port to complete all device monitoring; All experimental parameters can be set; Collect tensile displacement-tensile force-Corresponding curve of edge pressure and generationEXCELdata table

11. The zero point self calibration device for stretching displacement is used to ensure accurate collection of displacement values for low strength specification thin plates

12. Configure optical measurement synchronization trigger signal interface

13. Modular design of edge pressing mechanism, stretching mechanism, mold mechanism, power system, and measurement and control system, facilitating system maintenance and calibration
