Assembly Steps of Metal Stamping Dies

The stamping die assembly will affect the quality of stamping parts , the use and maintenance of the die, and the life of the die, which shows its importance in the stamping manufacturer. So what are the basic requirements for the assembly of stamping dies? According to the structural characteristics and technical conditions of the stamping die, it should be assembled according to a certain assembly sequence and method.

1. For the assembled stamping die, the upper die should slide up and down along the guide column smoothly and flexibly, and no tightness is allowed;

2. The gap of the punch and die should meet the requirements of the drawing, and the distribution should be uniform, and the working stroke of the punch or die should meet the requirements of the technical conditions;

3. All punches should be perpendicular to the assembly base of the fixed plate;

4. The relative position of the positioning and blocking device should meet the requirements of the drawing; the spacing of the blanking die guide plates should be consistent with the drawing, and the guide surface should be parallel to the center line in the feeding direction of the die; the guide with a pressure measuring device plate, its side pressure plate should slide flexibly and work reliably;

5. The relative position of the unloading and ejector device should meet the design requirements, the super-elevation is within the allowable range, and the working surface is not allowed to have inclination or unilateral deflection, so as to ensure that the stamping parts or waste can be unloaded and ejected smoothly;

6. The blanking hole or discharge trough should be unblocked to ensure that stamping parts or waste can be discharged freely;

7.The standard parts should be interchangeable; the cooperation between the fastening bolts, positioning pins and their holes should be normal and good.
