Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment of brake shoes / brake plates, in particular to a heat treatment device for microporous synthetic brake shoes / brake plates. Background Art

[0002] Microporous synthetic brake shoes / brake pads are made by cold pressing process. After being pressed and formed, the brake shoes / brake pads are not completely solidified. After heat treatment, the brake shoes / brake pads are completely solidified and no longer expand and deform, and the shape of the brake shoes / brake pads can be fixed. Microporous synthetic brake shoes / brake pads need to be heat treated after being pressed and formed. During the heat treatment, the existing microporous synthetic brake shoes / brake pads do not have any requirements for the placement of the brake shoes / brake pads. The brake shoes / brake pads are placed in an oven with the steel back (i.e., the back of the shoe) at the bottom and the friction surface of the brake shoes / brake pads at the top for heat treatment. This heat treatment method cannot control the expansion and deformation of the brake shoe arc or the expansion and deformation of the brake pad friction surface, resulting in uneven heating of the brake shoes / brake pads and uneven heat treatment effects, which makes the expansion of the brake shoe friction surface arc / brake pad friction surface larger, affecting the uniformity of the physical and chemical properties of the brake shoes / brake pads, such as density, compression strength, impact strength and bending strength. Moreover, after the brake shoe / brake pad is installed on the vehicle, the arc expansion of the brake shoe friction surface is large and does not fit the wheel tread, or the brake pad friction surface expands large and does not fit the brake disc, which increases the grinding amount of the friction surface and increases the running-in time, affecting the use effect of the brake shoe / brake pad in the initial stage of installation and affecting the quality of the product.

[0003] Therefore, it is necessary to provide a heat treatment device that improves the uniformity of the physical and chemical properties of microporous synthetic brake shoes / brake pads. Utility Model Content
