Ef40-4 automatic heading machine adopts servo and hydraulic power to drive the equipment. All actions of the whole machine include clamping, forming, positioning and die changing. The hydraulic power source is matched with the high-pressure piston pump imported from Japan. The maximum pressure of the hydraulic system can reach 23.5mpa, with stronger working output.
This machine is used to hold the workpiece tightly by clamping die and cold extrude the workpiece by forming die. The feeding position of the workpiece is designed with front and rear positioning, and the switching of the four position forming die is automatically completed by the ball screw driven by the servo motor.
The disassembly actions of the machine include clamping, forming, positioning and mold changing.
Action purpose and principle of automatic heading machine:
1. Clamping (the oil cylinder pushes the clamping die to clamp the workpiece);
2. Forming (the oil cylinder pushes the forming die to cold extrude the product);
3. Positioning (when placing pipe fittings, raise and clamp the pipe fittings and then lower to avoid the forming mold);
4. Mold change (servo motor + ball screw drive, high mold change positioning accuracy).
