Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic bracket punching dies, in particular to a main axis four-position multi-hole punching die. Background Art

[0002] The basic working principle of punching processing is to push the mold through mechanical force or hydraulic pressure, so that the upper mold of the mold falls quickly and exerts a certain force on the surface of the square tube and metal plate, so that the square tube and metal plate form the required convex and concave deformation to achieve the required forming or punching. The punching mold falls vertically, and its working principle is simple, with high processing accuracy, low cost, high production efficiency and wide applicability. Since the existing mold is punched on both sides and is positioned on the top, the one-time debugging based on the upper positioning is too limited, and the flipping operation is even more inconvenient for debugging. In addition, when punching holes on both sides of the square tube, it is easy for the hole position to be not centered, and the large dimensional error affects the adaptation and installation. Therefore, a spindle four-position multi-hole punching mold is required.

[0003] The existing spindle four-position multi-hole punching die cannot effectively improve the accuracy of maintaining consistent punching centers during operation, and cannot effectively improve the stamping efficiency of the die. Therefore, a spindle four-position multi-hole punching die is urgently needed. Summary of the invention
