Die for automobile brake disc

Abstract

The invention discloses a die for an automobile brake disc. The die for the automobile brake disc comprises a hydraulic cylinder and a lower die base. The output end of the hydraulic cylinder is movably connected with a hydraulic rod, a mounting plate is fixed at the tail end, away from the hydraulic cylinder, of the hydraulic rod, a cushion plate is fixed on the bottom of the mounting plate, second springs are welded on both sides of the bottom of the cushion plate, the cushion plate is connected with an upper die through a second spring, the bottom of the upper die is equidistantly providedwith punching needles, a lower die slot is arranged in the center position of the top of the lower die base, the surface of the lower die slot is provided with punching holes matched with the punchingneedles, and a first spring is welded at the center position inside the lower die base. According to the invention, when the upper die makes contact with the lower die slot through the second spring,a function of cushioning pressure is fulfilled, the direct high-pressure impact on the processing raw material is avoided, and the punching holes communicate with a material box, so that the flushedwaste can directly fall into the material box through the punching holes.

Description

technical field [0001] The invention relates to the field of automobile molds, in particular to an automobile brake disc mold. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping - is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. [0003] However, due to the long-term high-pressure impact of the commonly used molds, there is no good buffer, so the service life is not long, and after the mold is pressed, the parts are easily stuck in the mold after being subjected to high-pressure deformation. It will be very difficult to fetch, delaying production time and reducing work efficiency. The stamping die not only has the function...

[0003] However, due to the long-term high-pressure impact of the commonly used molds, there is no good buffer, so the service life is not long, and after the mold is pressed, the parts are easily stuck in the mold after being subjected to high-pressure deformation. It will be very difficult to fetch, delaying production time and reducing work efficiency. The stamping die not only has the function of stamping and deformation, but also has the function of punching, but the scraps that are punched out will get everywhere in the workplace and become a second-hand tool. secondary pollution
