Description

Technical Field

[0001] The present invention relates to the technical field of brake pad manufacturing, and in particular to a brake pad production stamping equipment and a production process. Background Art

[0002] In the production process of automobile brake pads, the raw materials of brake pads need to be processed. The processing of raw materials mainly involves stirring the raw materials to prevent the raw materials from condensing into lumps, thereby improving the uniformity of the mixed raw materials. This is a technical inspiration for the processing of raw materials;

[0003] Research on production raw material processing found the following problems:

[0004] When the raw materials are stirred during the production process, the mixed materials at the bottom of the main box are stirred evenly by multiple inclined material plates, filter screens and arc-shaped stirring rods. After the raw materials enter the main box, some of the raw materials are not stirred by the multiple inclined material plates, filter screens and arc-shaped stirring rods and directly enter the bottom of the main box. The raw materials that enter the main box first fall to the bottom and accumulate. When the agglomerated raw materials that enter the accumulated raw materials are not cut and crushed and enter the accumulated raw materials, the arc-shaped stirring rod is affected by the resistance of the accumulated raw materials during the stirring process. The arc-shaped stirring rod cannot disperse the agglomerated raw materials. When the raw materials enter the main box, some of the raw materials will stick to the inner wall of the main box, resulting in the accumulation of raw materials being discharged and some of the raw materials being stored inside the main box, thereby failing to improve the uniformity of the mixed raw materials.

[0005] At present, CN111998022A in the prior art discloses a high-temperature resistant ceramic brake pad and its production process, and discloses a production process of the brake pad. The invention is characterized by the rotation of multiple inclined tamping plates and their filter screens, so that the mixed material entering the main box can be stirred and dispersed first, and at the same time, the filter screen located on the side of the inclined tamping plate can effectively filter the mixed material dispersed to the inner wall of the main box under the action of centrifugal force, thereby effectively promoting the fusion efficiency of the mixed material, and the connecting rod located at the bottom of the barrel can effectively drive multiple arc-shaped stirring rods to rotate, and the staggered arc-shaped stirring rods can effectively stir the mixed material at the bottom of the main box evenly, and the cutting knives on three of the arc-shaped stirring rods can cut and break the lumps in the mixed material, thereby effectively promoting the uniformity inside the mixed material and improving the quality of friction material processing;

[0006] The present invention can mainly solve the problem that the brake pad raw material is not completely stirred after entering the main box and part of the raw material remains on the inner wall of the main box, resulting in the failure to improve the uniformity of the mixed raw materials.

[0017] A further embodiment of the present invention comprises the following steps:

[0018] S1: The raw materials for producing brake pads are fed into the main sleeve 201 through the feed cylinder 103 at the top of the main box 1;

[0019] S2: activating the motor 101 to enable the primary gear 2 to drive the secondary gear 202 to transmit, and at the same time the secondary gear 202 drives the primary sleeve 201 to rotate;

[0020] S3: The main sleeve 201 rotates to generate centrifugal force to keep the agglomerated raw materials rotating and cut by the main scraper 206 and the auxiliary scraper 207;

[0021] S4: The cut raw material passes through the filter screen 205 and enters the auxiliary sleeve 3. The auxiliary sleeve 3 rotates with the main gear 2 through the auxiliary gear 309 and generates centrifugal force.

[0022] S5: The auxiliary sleeve 3 swings the raw materials inside it through the centrifugal force, and stirs the raw materials through the lever 306 on the outer side of the auxiliary shaft 302 to improve the uniformity of the raw materials;

[0023] S6: The auxiliary sleeve 3 rotates and fits the lever 306 to generate heat. The auxiliary sleeve 3 absorbs the heat and transmits it to the airbag 308 to expand it and push the soft leather ring 307, thereby preventing the raw materials from remaining inside the auxiliary sleeve 3.

[0024] Beneficial effects:

[0025] 1. The motor drives the main gear to rotate, and the main gear drives the secondary gear to rotate at the same time. In this process, the main sleeve rotates with the secondary gear. The secondary gear generates centrifugal force when it rotates. The auxiliary scraper in the groove on the inner wall of the main sleeve is thrown out to the outside of the groove by the centrifugal force. When the auxiliary scraper is thrown out of the groove by the centrifugal force, there is a gap of one millimeter between the main scraper and the main scraper, so that the main scraper and the auxiliary scraper cut and crush the raw materials, thereby preventing the raw materials from agglomerating and affecting the forming effect of the brake pad.

[0026] 2. When the bulk raw materials enter the main sleeve without being cut, the raw materials are limited by the filter screen and are not filtered. At this time, the bulk raw materials are thrown away by the centrifugal force generated by the main sleeve, thereby preventing the raw materials from agglomerating and being discharged and collected.

[0027] 3. The auxiliary sleeve rotates along with the main gear through the auxiliary gear on the outer side. Centrifugal force is generated while the auxiliary sleeve rotates. After entering the auxiliary sleeve and during the process of entering the auxiliary sleeve, the raw materials are thrown to the inner wall of the auxiliary sleeve by the centrifugal force. The inner wall of the auxiliary sleeve is scraped and the raw materials are stirred through the six levers on the outer side of the auxiliary shaft, thereby preventing the raw materials from remaining inside the auxiliary sleeve.

[0028] 4. The six levers generate heat due to friction during rotation. The six levers are alternately arranged and divided into a group of three. The two groups are symmetrically arranged, and two levers are arranged between the annular through holes on the inner walls of every two auxiliary sleeves. The airbag inside the auxiliary sleeve expands due to heat and pushes the soft leather ring on the inner wall of the auxiliary sleeve. The soft leather ring is pushed outward. The electrostatic material used by the soft leather ring prevents the surface of the soft leather ring from being adsorbed and residual brake pad raw materials. BRIEF DESCRIPTION OF THE DRAWINGS

A brake pad production stamping equipment according to any one of claims 1 to 4, characterized in that: The production process of brake pads includes the following steps: S1: raw materials for producing brake pads are fed into the main sleeve (201) through the feed cylinder (103) at the top of the main box (1); S2: activating the motor (101) so that the main gear (2) drives the secondary gear (202) to transmit, and at the same time the secondary gear (202) drives the main sleeve (201) to rotate; S3: the main sleeve (201) rotates to generate centrifugal force so that the agglomerated raw materials keep rotating and are cut by the main scraper (206) and the auxiliary scraper (207); S4: After the cutting, the raw material passes through the filter screen (205) and enters the auxiliary sleeve (3). The auxiliary sleeve (3) rotates along with the main gear (2) through the auxiliary gear (309) and generates centrifugal force. S5: the auxiliary sleeve (3) swings the raw materials inside thereof by centrifugal force, and stirs the raw materials by means of the lever (306) on the outer side of the auxiliary shaft (302), thereby improving the uniformity of the raw materials; S6: The secondary sleeve (3) rotates and fits the lever (306) to generate heat, and the secondary sleeve (3) absorbs the heat and transmits it to the airbag (308), causing it to expand due to the heat and push the soft leather ring (307), thereby preventing the raw material from remaining inside the secondary sleeve (3).
