Die-spotting press CMHE-LJ series

servo-hydraulicforgingdrawing

Frame structure: welded frame structure made of high quality steel plate and annealing process, confirm the elastic deformation in maximum pressure through finite element analysis, guiding of moving bolster by eight-face linear guide way, enhance the stability of moving bolster movement and high eccentric pressing force; Ease operation: user friendly HMI, ease for setting parameters and recipe storage; Control system: PLC + HMI (Siemens brand), refer to pressing technology requirement set the parameters on HMI such as pressure, position, hold pressure, multi-pressing, etc; Accuracy monitoring: used for linear scale and pressure sensor to monitor the position and pressure, enhance the pressing accuracy; Position accuracy: repeatability of ram position achieve to ±0.01mm, control the scrap rate of products caused by machine accuracy; Pressing accuracy: repeatability of ram pressure achieve to ±3%, control the scrap rate of products caused by machine accuracy; Low noise level: used of servo motor driving system, fulfill different speed and pressure of pressing requirement, ensures the stability of movement, lower noise level; Ram cylinder designed: used of forged steel and its inner surface is finely grinded, prolonging working life under high pressure; Hydraulic circuit designed: used of advance two-way cartridge valve, high reliability and less impact on changing of different pressing stage; Selectivity: different of ejection type can be selected such as lower ejector, upper ejector and lower & upper ejector, suitable for different type of pressing technology requirement; Ease for maintenance: module structure designed as different function requirement,
