Mold Requirements For Cold Heading Machining

Dec 02, 2020

During cold heading, the blank is subjected to three-way compressive stress in the die, which significantly increases the deformation resistance, which makes the stress of the die much larger than that of ordinary stamping dies. When cold extrusion of steel, the stress of the die often reaches 2000MPa~ 2500MPa. For example, a low-carbon steel cup with a diameter of 38mm, a wall thickness of 5.6mm, and a height of 100mm is made as an example. When cold heading is used, the maximum deformation force is only 17t, while when cold extrusion is used, the deformation force is 132t. , At this time, the unit pressure acting on the cold extrusion punch is above 2300MPa. In addition to high strength, the mold also needs to have sufficient impact toughness and wear resistance.


Adjustment skills of cold heading machine


1. Emergency stop and keep pressing the emergency stop button on the operation panel of the control cabinet, the equipment stops running.  

2. Reset Press the two reset switches on the counter operation panel to reset the preset number and processing number respectively.

3. Pull off the total power, the data on the counter remains unchanged. After restarting the power supply, the equipment will continue to process parts until it reaches the preset number and then stops.
