Description

Technical Field

[0001] The utility model relates to the technical field of punching devices, in particular to a punching device for automobile brake disc production. Background Technique

[0002] During the braking process of the brake disc, a large amount of frictional heat will be generated on the brake disc. If the heat cannot be dissipated in time, it will cause the brake disc to overheat, reduce the braking performance and even pose a danger of brake failure. Therefore, a number of heat dissipation holes are provided on the brake disc. Punching can increase the surface area of the brake disc, improve the heat dissipation effect, enable the brake disc to dissipate heat faster, and maintain the stability of the braking performance. The existing punching method for automobile brake disc production is to manually place the brake disc on the punching disc, then tighten the bolts to fix the brake disc, and start the punching process. After the punching process is completed, the worker disassembles the brake disc fixing fixture and finally removes the brake disc.

[0027] The output shaft of the hydraulic cylinder 2 penetrates through the fixing plate 1 and is slidably connected to the fixing plate 1. The first disc 3 and the second disc 5 are identical in shape and size. The top end of the discharge frame 11 is fixedly connected to the bottom end of the fixing plate 1. The discharge frame 11 can be conveniently arranged to facilitate the sliding out of debris and the brake disc body 8. The pressing assembly 7 includes a pressing rod 701 that is slidably connected inside the first disc 3 and penetrates through the first disc 3. A pressing spring 702 is provided outside the pressing rod 701. The top end of the pressing rod 701 is fixedly connected to a baffle 703, and the bottom end of the pressing rod 701 is fixedly connected to a pressing plate 704. The setting of the pressing assembly 7 enables the brake disc body 8 to be fastened without manual operation by workers, improving work efficiency.

The cooperation of the fan and the condensation circulator 1602 can cool the electric drill 4 and the brake disc body 8. The filter screen 1605 can isolate the dust in the air. The wind blown by the intake fan 1604 pushes the debris on the device to roll inside the discharge frame 11, and the debris falls into the collection drawer 14 through the slag discharge grille 13. Pulling out the collection drawer 14 can transfer and recycle the slag. The intake air cooling component 16 can cool the brake disc body 8 and the electric drill 4, and can also blow the debris generated by drilling.
