Compared with the prior art, the utility model has the following advantages:

1. The lower mold base of the utility model is connected with a plurality of supporting mold columns capable of supporting the flange end plate and arranged along the circumferential direction, and an upper mold base that can move up and down relative to it is arranged above the lower mold base. It is connected with a plurality of punching needles corresponding to the supporting mold columns one by one and capable of punching through holes on the flange end plate. In the punching process of the flange end plate, as long as the upper die base moves down once, the multiple punching needles on the upper die base will punch out the required number of through holes on the flange end plate at one time, and the production efficiency is improved. Greatly improved, and avoiding the process of rotating and moving the flange end plate in the traditional process, the position and dimension accuracy of the through hole is also improved, which improves the product quality, and the waste generated by punching the through hole can pass through the discharge hole on the supporting mold column And the discharge channel on the lower mold base is discharged, and the discharge of waste is also very convenient.

2. The positioning column on the support form column of the utility model cooperates with the prefabricated hole on the flange end plate to prevent the flange end plate from moving in the horizontal direction, and the positioning plate above the support form column prevents the flange end plate from moving vertically. Direction of movement, so as to limit the flange end plate very well, avoid movement during the process of punching through holes, and ensure dimensional accuracy.

3. The utility model has the advantages of simple structure, high production efficiency, and high dimensional accuracy of processed products, which is suitable for popularization and application.
