Abstract

The invention provides an automatic steel backing plate broaching device, which comprises an upper die base, a movable supporting plate, a lower die base and a forming device, wherein the upper die base is provided with a guide post and a pressure spring; the movable supporting plate is respectively connected with the guide post and the pressure spring; the lower die base is parallel to the movable supporting plate at an interval; and the forming device comprises a blade fixing device, a blade, a press block, a slide block, a fixed block and a wedge, wherein the blade fixing device is arranged under the movable supporting plate; the blade is arranged in the blade fixing device, and the surface of the blade is provided with broached teeth; the press block is arranged on the upper die base and is inserted in the movable supporting plate; the slide block is arranged on the lower die base; the fixed block is arranged on the lower die base; and the wedge is arranged between the slide blockand the fixed block. The broached steel backing plate has high braking safety, and is more suitable for brake sheets of heavy-duty automobiles and trucks; and the product appearance and flatness are not influenced. A die processing mode is adopted, so the whole production process is more stable, the tooth root is firm and difficult to fall off, and the device is suitable for mass production.

Description

Technical field [0001] The invention relates to the technical field of automobile parts, in particular to a steel back automatic drawing device for automobile brake pads and a use method thereof. Background technique [0002] The brake pads of small and medium-sized cars generally include steel backs and friction blocks, where the friction blocks are bonded by friction materials such as reinforcing materials, adhesives and fillers; the steel back plays the role of bearing and supporting the friction blocks and is made of steel stamping . When braking, the steel back is pushed by the brake caliper, and its friction block is in contact with the brake disc or drum to rub, and the purpose of the vehicle is to slow down and brake through friction. Since the brake pads are the most critical safety parts in the car's braking system, the brake pads play a decisive role in the effectiveness of all braking. Therefore, the bonding firmness of the steel back to the friction material and th...
