Description

Technical Field

[0001] The utility model relates to the technical field of brake pads, in particular to a drum type brake pad punching and clamping device. Background Art

[0002] Brake pads are also called brake leathers. In the braking system of a car, brake pads are the most critical safety parts. The quality of all braking effects is determined by brake pads. Therefore, good brake pads are the protectors of people and cars. Brake pads are generally composed of steel plates, adhesive insulation layers and friction blocks. The steel plates must be painted to prevent rust. The SMT-4 furnace temperature tracker is used to detect the temperature distribution of the coating process to ensure quality. The insulation layer is made of non-heat-conducting materials for the purpose of heat insulation. The friction block is composed of friction material and adhesive. When braking, it is squeezed on the brake disc or brake drum to generate friction, thereby achieving the purpose of decelerating and braking the vehicle. Due to friction, the friction block will gradually wear out. Generally speaking, the lower the cost of the brake pad, the faster it wears;

[0003] Among the existing brake pads, most are fixed clamping devices that are difficult to move and change direction, which makes it quite cumbersome for operators to adjust the direction of the brake pads. In addition, due to their special structure, installing and removing the brake pads is also very time-consuming. In view of this, we propose a drum brake pad punching clamping device.
