Description

Technical Field

[0001] The utility model relates to the technical field of brake pad preparation, in particular to a brake pad cold pressing device. Background Art

[0002] Brake pads, also called brake pads, refer to friction materials fixed on brake drums or brake discs that rotate with the wheels. The friction linings and friction pads bear external pressure, generating friction to achieve the purpose of vehicle deceleration. The heat insulation layer is composed of non-heat-conducting materials for the purpose of heat insulation. The friction block is composed of friction materials and adhesives. When braking, it is squeezed on the brake disc or brake drum to generate friction, thereby achieving the purpose of vehicle deceleration and braking. Automobile brake pads are generally composed of steel backing, adhesive heat insulation layer and friction blocks.

[0003] In view of the existing patent CN202220043261.1, a disc brake pad cold pressing mold is proposed. The device increases vacuum in the vulcanization process. Through the vacuum treatment process, the volatile matter and moisture of the material in the vulcanization process are reduced, and the cracks and blistering of the brake pad in the vulcanization process are greatly reduced, which effectively improves the technical effect of product quality and solves the commonly used processing technology of passenger car disc brake pads: batching - mixing - cold forming - vulcanization - grinding - inspection - packaging. The car brake pads produced according to this process often have cracks, bubbles and other phenomena, which lead to increased costs for pressing brake pads and reduced product quality. The cold pressing device fixes the female mold and the male mold through the cooperation of screws and nuts. The cooperation of multiple screws and nuts has the advantage of being able to firmly fix the female mold and the male mold. However, when the female mold and the male mold are to be disassembled and replaced, it is necessary to find a wrench suitable for the nut, and use the wrench to disassemble the screws one by one. In order to firmly fix the female mold and the male mold, multiple screws and nuts are generally installed. When multiple screws are disassembled, it is too troublesome. Therefore, it does not meet the existing needs. We have proposed a brake pad cold pressing device. Utility Model Content
