Description

Technical Field

[0001] The invention relates to the technical field of metal plate processing devices, and in particular to a corrugated sheet bending device. Background Art

[0002] The transformer will generate a lot of heat when working. If the heat is not discharged in time, the transformer temperature will be too high and cause the transformer to trip. In order to ensure the normal operation of the transformer, the heat generated by the transformer needs to be discharged. Folding fins made of metal are often installed on the transformer. The folded fins can export the heat in the transformer. The types of folded fins mainly include flat type, corrugated type, serrated type, louver type, porous type, etc.

[0003] In the related art, in processing corrugated folded fins (such as Figure 1 ), a metal plate is placed in the lower die of a workbench, and the piston rod of a hydraulic cylinder drives the lower die to punch the metal plate. The upper and lower dies are closed, and corrugated convex plates are connected to the upper and lower dies. The corrugated convex plates in the upper die and the corrugated convex plates in the lower die are arranged alternately. Through the cooperation of the corrugated convex plates in the upper and lower dies, the metal plate is punched into a corrugated folding fin.

[0004] In view of the above-mentioned related technology, all the corrugated convex plates in the upper mold and all the corrugated convex plates in the lower mold cooperate in stamping, and the corrugated convex plates will pull the metal plate, causing the metal plate to deform; when processing the grooves of the corrugated sheet (such as Figure 1 ) is deeper, the corrugated convex plate pulls the metal plate more. Since other corrugated convex plates also pull the metal plate, the stress between the metal plates is greater, and the metal plate is prone to being pulled and cracked, which reduces the product quality.

Since the lower fixed plates 3 and the upper fixed plates 5 on both sides of the lower movable plate 2 are stationary, the lower movable plate 2 gradually pulls the metal plate and enters between the two upper fixed plates 5. During the rising process of the lower movable plate 2, the lower movable plate 2 pushes the upper movable plate 4 to rise until the top surface of the upper movable plate 4 contacts the top plate 131. At this time, the upper movable plate 4 no longer rises, and the lower movable plate 2 cooperates with the upper movable plate 4 to flatten the metal plate, and the upper fixed plate 5 cooperates with the lower movable plate 2 to press the metal plate into a corrugated shape. By bending the metal plates one by one instead of directly stamping, it is possible to avoid tearing of the metal plate due to excessive pulling caused by the deep depth of the groove 011 of the corrugated sheet 01, thereby improving product quality.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
