Description

Technical Field

[0001] The utility model relates to the technical field of train brake assembly, in particular to a brake pad cold pressing and forming device. Background Technique

[0002] The train brake pad is an important part of the train braking system and a key component for controlling the running speed of the train. During braking, the brake shoe clamps the wheel through the brake pad, making the wheel lose its free rotation, so as to achieve the purpose of braking. The brake pad includes a brake pad steel back and a friction body. During production, the powder mixture needs to be pressed into shape and pressed with the brake pad steel back to form an integral structure. Since the brake pad steel back is at the lower end of the friction body, the brake pad steel back needs to be placed at the lower end of the mold cavity and always keep the corresponding position with the friction body consistent.

[0003] However, in the existing production process of brake pads, due to the deep groove structure of the mold cavity, it is difficult to place and position the brake pad steel back, resulting in difficulty in keeping the corresponding position between the brake pad steel back and the friction body consistent, which brings trouble to production and manufacturing. Moreover, the existing brake pad production equipment has a low degree of automation and is difficult to meet the development needs of intelligent manufacturing. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems existing in the above background technique, and provide a brake pad cold pressing and forming device. By setting a brake pad steel back pushing unit, a brake pad pushing unit and a brake pad lifting assembly, it improves the product quality of the brake pad, realizes the rapid demoulding of the brake pad, and improves the production efficiency and the degree of automation of the equipment.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a brake pad cold pressing and forming device, including a forming press. A brake pad upper pressing die is arranged on the lower end surface of the slide block of the forming press. A brake pad cavity seat is arranged on the workbench of the forming press. A brake pad lifting assembly is arranged inside the workbench. A pressing cavity is arranged in the middle of the brake pad cavity seat. A brake pad steel back pushing unit is arranged on one side of the upper end of the brake pad cavity seat. A brake pad pushing unit is arranged on the other side of the upper end of the brake pad cavity seat. And the brake pad steel back pushing unit and the brake pad pushing unit are respectively located on both sides of the pressing cavity.

[0006] The brake pad lifting assembly includes a brake pad lifting guide column, a brake pad lifting seat, a brake pad support mold, and a brake pad lifting cylinder. The brake pad lifting guide column is arranged in the brake pad cavity seat. The brake pad lifting seat is slidably arranged up and down on the brake pad lifting guide column. The brake pad support mold is arranged on the upper end face of the brake pad lifting seat and is slidably matched in the pressing cavity. The brake pad lifting cylinder is arranged at the lower end of the workbench, and the output end of the brake pad lifting cylinder is connected to the brake pad lifting seat. The brake pad lifting assembly is used to load the brake pad steel back and lift the pressed brake pad to the outer end of the pressing cavity, facilitating the demolding of the brake pad.

[0007] Preferably, the brake pad steel back feeding unit includes a brake pad steel back feeding bracket, a brake pad steel back feeding cylinder, and a brake pad steel back blanking station. The brake pad steel back feeding bracket is arranged on the brake pad cavity seat. The brake pad steel back feeding cylinder is arranged on the brake pad steel back feeding bracket. The brake pad steel back blanking station is arranged on one side close to the pressing cavity. A brake pad steel back feeding block is arranged on the output end of the brake pad steel back feeding cylinder.
