Introduction：

Automotive half-shaft pre-heading machine is a domestic energy-saving, material-saving, less cutting and electromechanical integration high-tech pressure forming equipment, especially suitable for automotive half-shaft, general flange, gear, cam disc, grid head, high-strength large-size bolts, etc. Performance characteristics: column guided, economical; computer-optimized design; The hydraulic system adopts two-way cartridge valve integrated control, anti-leakage flange pipeline system, and reduces leakage points; It has three process specifications of adjustment, manual and semi-motion, and two control modes of fixed range and constant pressure. 

Control systems:

1. Conventional configuration: PLC electrical control system, open-loop control; The pressure gauge shows the pressure and the stroke switch controls the displacement.

2. CNC system: PLC electrical control system; closed-loop control; Pressure sensor, proportional pressure valve to control pressure; Displacement sensor controls displacement; Touch screen display, set pressure, displacement and other parameters; The process program can be set according to user requirements, and the action is sensitive and reliable; Man-machine dialogue, the hydraulic press pressure, displacement and other parameters can be randomly changed and adjusted.

3. Servo control system: servo motor, drive, encoder, duplex quantitative pump combination instead of asynchronous motor constant power combination and proportional pressure valve; closed-loop control; Control the motor speed through pressure setting, control the displacement through the encoder and displacement sensor, and realize more accurate control of the pressure, displacement, speed and other parameters of the hydraulic press; Human-machine dialogue, highly flexible work, fast programming and control of workflows, various parameters (pressure, displacement, speed, etc.) on demand.

Application: 

This series of hydraulic press is special for automobile half-shaft pre-upsetting and spline end upsetting rough process; It can also complete the process of upsetting the end of the metal bar stock. Optional functional accessories: This series of hydraulic presses includes a complete set of automatic tightening, opening and closing mold base.
