Embodiment Construction

[0020] Embodiments of the invention will be described in detail below, examples of which are illustrated in the accompanying drawings.

[0021] The embossing process of the friction material surface on the back plate for the brake lining of the present invention will be further described in detail below.

[0022] Combined with the accompanying drawings, Figure 1-5 , an embossing process for a brake lining with a back plate attached to a friction material surface, the specific steps of the process include:

[0023] Step 1: Make a mold with an embossing device, and cut the steel back;

[0024] Step 2: Put the steel back into the bottom of the mold, and use a punching machine for cold pressing;

[0025] Step 3: Obtain a finished brake lining with embossed depth and friction texture on the surface.

[0026] In this embodiment, the embossing depth is within 0.5 mm, and the effect of the friction texture is greater than the surface roughness Ra2.5.

[0027] In this embodiment, ...

Abstract

The invention discloses an embossing process for a friction material attaching surface of a back plate for a brake lining. The process comprises the following specific steps of: firstly, a mold with an embossing device ismanufactured,and a steel back is cut; secondly, the steel back is placed at the bottom of the mold, and a punching machine is adopted for cold pressing; and thirdly, a brake lining finished product with the embossing depth and friction textures in the surface is obtained. The lining meeting the roughness requirement is stamped through mold embossing, dust is effectively prevented from being generated in process production, and the requirements for environmental protection and automobile driving safety are met, so that the braking effect of the brake pad is improved, and meanwhile, the body health of production personnel is guaranteed; and wide applicability is achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical preparation, in particular to an embossing process for the surface of a friction material attached to a back plate for a brake lining. Background technique [0002] In order to improve the driving safety of the car and improve the braking effect of the brake pads, when the new car starts to run or after the brake pads are replaced, the brake pads should be run-in for a long period of time and many times. After running-in, the protruding points of the brake pads are smoothed, so that the brake disc and the brake pads can achieve a better fit and achieve the best braking performance. [0003] In the production process of the brake lining, it needs to be sand blasted. During the sand blasting process, a large amount of dust will be generated. This process is seriously polluting the environment and needs to be improved urgently. In order to improve this technical problem, the inventors proposed a ...
