Problems solved by technology
[0004] In order to solve the above problems, the present invention provides an asbestos-free motor vehicle friction material surface spraying equipment, which can solve the problem that the existing spraying equipment cannot spray the raw materials on the steel back uniformly enough, and after spraying the friction material, it cannot be timely Hot press forming, when the friction material is in a static state for a long time, it is easy to condense, and the heat pressing position of the brake pad is not accurate during hot press forming; it can realize the function of uniform and accurate spraying on the surface of the friction material, and has the ability to apply steel The raw materials on the back are sprayed evenly enough. After the friction material is sprayed, it can be hot-pressed in time. The friction material is not easy to condense, and the heat-pressed position of the brake pad is accurate during hot-press forming.

Embodiment Construction
[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0022] like Figure 1 to Figure 5 As shown, an asbestos-free motor vehicle friction material surface spraying equipment includes a base plate 1, a rotating device 2, a pressure device 3, and a spraying device 4. The number of the rotating devices 2 is two, and the rotating device 2 is installed on the base plate 1. On the end face, the pressure device 3 is installed between the inner sides of the lower end of the rotating device 2 , the spraying device 4 is installed between the inner sides of the upper end of the rotating device 2 , and the pressure device 3 is located directly belo...

The invention relates to surface spraying equipment for asbestos-free motor vehicle friction materials. The equipment comprises a bottom plate, two rotating devices, a pressure device and a spraying device; the two rotating devices are mounted on the upper end surface of the bottom plate; the pressure device is mounted between the inner side surfaces of the lower ends of the rotating devices; thespraying device is mounted between the inner side surfaces of the upper ends of the rotating devices; and the pressure device is located under the spraying device. By the aid of the equipment, the problems that raw materials on steel backs cannot be sprayed evenly enough by existing spraying equipment, hot-pressing molding cannot be performed timely after spraying of friction materials, the friction materials are in the stationary state for a long time and are prone to coagulation, hot-pressing positions of brake pads are inaccurate during hot-pressing molding and the like can be solved; and the function of even and accurate spraying of the surfaces of the friction materials can be realized.
Description
technical field [0001] The invention relates to the technical field of friction material processing, in particular to an asbestos-free motor vehicle friction material surface spraying equipment. Background technique [0002] The friction material is characterized by good friction coefficient and wear resistance, as well as certain heat resistance and mechanical strength, which can meet the performance requirements of vehicle or mechanical transmission and braking. During the processing of non-asbestos friction materials, the raw material formula of the brake pads must be mixed together to make the materials evenly stirred, and then the raw material powder is sprayed on the steel back, and then the powder and the steel back are hot-pressed by the hydraulic machine and the mold. The basic shape of a brake pad. [0003] In the existing spraying equipment, the raw materials on the steel back cannot be sprayed evenly enough, so that the surface distribution of the friction mater...
