The design principle of hardware mold positioning part:

1, positioning support point and support surface design: positioning should have at least three support points, two guiding points and a set point. There should be enough distance between the positioning support point and the guide point to ensure the billet has a higher positioning accuracy and stability, as far as possible to use the supporting surface instead of the supporting point.

2, positioning direction and position design: single operation, feeding direction from right to left or from front to back is appropriate. When feeding from right to left, the guide point is located at the rear; When feeding from front to back, the guide point is located on the left side.

3, rough positioning and fine positioning design: multi-process joint stamping processing, should be equipped with initial positioning (rough positioning) and final positioning (fine positioning). When multiple processes are pressed separately, the positioning datas of the preceding and following processes should be consistent.

Hardware mold processing design assembly process:

Several basic knowledge that should be paid attention to in the assembly process are;

1, review the drawing, really understand the drawing to understand the designer's design side is the most important, otherwise it is the blind people feel the elephant.

2. Check whether the shape and size of the workpiece accessories are consistent with the drawings

Hardware mold design, processing and assembly start:

1. Clearance, whether the clearance between the workpiece and the template is reasonable punching and blanking mold clearance is reasonable.

2, avoid, positioning parts before processing parts, such as whether there is a avoid, whether enough.

3, spring force, workpiece ejection device spring force touch plate unloading force is enough force, spring compression and prepressure is enough, unreasonable.

Basically, you should pay attention to these when you set up, the rest are based on experience!
