Description

Technical Field

[0001] The utility model relates to the technical field of brake pad processing equipment, in particular to a brake pad steel back thorn raising die. Background Art

[0002] Brake discs are brake materials that must be installed in vehicles such as cars and motorcycles, and their performance directly affects the safety and reliability of vehicles. Usually, pricking the steel back of the brake pad can increase the shear strength between the brake pad and the friction block material, and at the same time increase the bonding strength between the brake pad and the friction material. The more commonly used pricking equipment in the prior art generally uses a tool to pierce the steel back material to perform the pricking operation, but the efficiency of this pricking operation is extremely low, the number of pricking operations each time is small, and the pricking of a single steel back requires repeated pricking operations dozens of times. After pricking, the flatness of the steel back is easily damaged, affecting product quality and causing the product to be scrapped; in addition, the prior art also discloses a patent application entitled "A two-way hook and pricking device and processing method for the steel back of a brake pad" with a publication number of "CN116021092A", which discloses that it includes: A workbench and a thorn-removing plate, the thorn-removing plate is arranged on the top of the workbench, and a clamping rotating assembly is arranged on the outer wall of the workbench, wherein: the clamping rotating assembly includes a limit groove, a clamp, a slider, a mounting plate, a limit rod and a clamping cylinder, the limit grooves are arranged on both sides of the top of the outer wall of the workbench, and the slider is slidably embedded in the inner part of the limit groove. Although this patent application improves the thorn-removing efficiency to a certain extent, it still needs to be done twice for bidirectional thorn-removing of the steel back, and the efficiency still needs to be improved, and the problem of damaging the surface quality of the steel back still exists when the bidirectional thorn-removing is done in two times.

Regarding how the rack plates are installed in combination, specifically, a through hole 114 and a plurality of spaced rack plate insertion holes are provided in the left sliding block 112 and the right sliding block 113, and the width of the rack plate insertion hole and the thickness of the rack plate are inserted in an insertion fit, and the through hole 114 is used to insert and install a fixing rod, and the fixing rod is used to pass through a plurality of rack plates inserted into the rack plate insertion holes to relatively fix the rack plate and the sliding block, that is, after a plurality of rack plates are inserted into the rack plate insertion holes of the sliding block, they are penetrated and connected to the sliding block by the fixing rod.

[0042] See attached Figure 4 and 8The fixed block is detachably mounted on the lower support plate 201 of the lower mold 200 by screws.
