Description

Technical Field

[0002] Brake pads are generally composed of a steel back and a friction block, which are stacked. The steel back is used for the installation of the brake pad. The friction block is composed of a friction material and an adhesive, and is used to generate friction to achieve the purpose of vehicle deceleration and braking. At present, brake pads are usually obtained by hot pressing with a hot press. During the production process, the friction block raw material needs to be weighed, and then the friction block raw material and the steel back are stacked and added to the cavity of the hot press production mold. The hot press is used to press the friction block raw material so that it is formed and adheres to the steel back and is integrated with the steel back to form a finished brake pad. The finished brake pad is taken out of the cavity, and then the cavity of the production mold is cleaned and sprayed with a demolding machine to facilitate the next production process.

The feeding linear module 7 drives the material taking and feeding assembly to add the received main material into the production mold. At the same time, the pre-pressing linear module 8 drives the pre-pressing assembly to pick up the pre-pressing mold placed on the steel back and the pre-pressing device; 5. The flattening linear module 9 drives the flattening assembly to flatten the main material in the production mold, and the flattening of the main material is achieved through the rotation of the stirring shaft 39 and the reciprocating movement of the stirring top plate 33; 6. The pre-pressing linear module 8 pre-presses the flattened main material through the pre-pressing die taken by the pre-pressing component; 7. The feeding linear module 7 drives the material taking and feeding assembly to add the received auxiliary materials into the production mold. At the same time, the pre-pressing linear module 8 drives the pre-pressing assembly to place the pre-pressing mold back onto the steel back and the pre-pressing device; 8. The flattening linear module 9 drives the flattening assembly to flatten the auxiliary materials in the production mold. The flattening of the auxiliary materials is achieved through the rotation of the stirring shaft 39 and the reciprocating movement of the stirring top plate 33. At the same time, the finished product taking linear module 13 drives the taking assembly to take the steel back from the steel back and the pre-pressing device; 9. The finished product taking linear module 13 drives the taking component to place the steel back on the production mold of the hot press 5, and the hot press 5 drives the production mold to move to the inside of the hot press 5 to press the brake pad; 10. The feeding linear module 7 drives the feeding and taking components to move to the weighing device 1 to receive the main material, and repeat the next cycle, and the automatic production of brake pads is realized by repeating the cycle.
