Description

Technical Field

[0001] The present invention relates to the technical field of brake pad preparation, and more particularly to a low-metal brake pad preparation system. Background Art

[0002] Automobile brake pads, also known as automotive brake linings, refer to the friction materials fixed on the brake drums or brake discs that rotate with the wheels. The friction linings and friction pads among them bear external pressures and generate frictional forces to achieve the purpose of vehicle deceleration. The friction blocks are composed of friction materials and adhesives. When braking, they are pressed against the brake discs or brake drums to generate friction, thereby achieving the purpose of vehicle deceleration and braking.

[0003] Common friction materials are mostly powdery materials, which are prone to accumulation during the feeding process, and then prone to uneven distribution of materials during the hot pressing process. At the same time, during daily use, the brake temperature mainly concentrates at 100°C - 200°C, and reaches 350°C during emergency braking at high speeds. If it is a continuous downhill road condition, the braking temperature will rapidly rise under high load conditions and reach above 400°C. The braking performance of brake pads with uneven material distribution will be greatly reduced when the temperature exceeds 400°C, and even the braking ability will be lost. After long-term use, the friction pads will crack. Continuing to use under cracked conditions will cause some brake pads to fall off, thereby leading to ineffective braking, resulting in property losses and personal injuries. Therefore, a low-metal brake pad preparation system is needed to solve the above problems. Summary of the Invention

Detailed Embodiments

[0015] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0016] Such as Figures 1 to 5As shown, a low-metal brake pad preparation system includes a chassis 1. At the center of the upper end of the chassis 1, a support frame 2 is installed. Around the support frame 2 at the upper end of the chassis 1, a feeding support platform 3, a hot pressing support platform 4, and a discharging support platform 5 are installed. A stepping motor 6 is installed on the support frame 2. At both ends of the support frame 2, support disks 7 are installed. On one side of the support disk 7, there are several bumps 8. The output end of the stepping motor 6 is rotationally connected to a support rod 9. The output end of the stepping motor 6 is coaxially connected to a support column 10. The upper end of the support column 10 is rotationally connected to a spring shock absorber 11. One end of the spring shock absorber 11 is rotationally connected to the support rod 9. The stepping motor 6 is electrically connected to the on-site power supply.

[0017] In this embodiment, at one end of the support rod 9, an installation platform 12 is installed. A pressing template 13 is installed on the installation platform 12. On one side of the lower end of the pressing template 13, a rotating shaft 14 is installed. A baffle 15 is rotationally connected to the rotating shaft 14. A torsion spring 16 is sleeved on the rotating shaft 14. One end of the torsion spring 16 is installed on the lower side of the baffle 15. The pressing template 13 can be replaced according to production needs.

[0018] In this embodiment, on the upper end of the feeding support platform 3, a first groove 17 is provided. On the inner upper wall of the first groove 17, a material injection port 18 is installed. On the upper end of the hot pressing support platform 4, a second groove 19 is provided. On the inner upper wall of the second groove 19, a hydraulic rod 20 is installed. At the bottom end of the hydraulic rod 20, a module 21 used in cooperation with the pressing template 13 is installed.

[0019] In this embodiment, at one end of the discharging support platform 5, a resisting block 22 is provided. At a position near the middle of the discharging support platform 5, an inclined discharging groove 23 is provided.

[0020] In this embodiment, arc-shaped grooves 24 are provided on the feeding support platform 3, the hot pressing support platform 4, and the discharging support platform 5. The rotating shaft 14 slides in the arc-shaped grooves 24. The feeding support platform 3, the hot pressing support platform 4, and the discharging support platform 5 are connected by arc-shaped support plates 25.

[0021] The working principle of the present invention is as follows: The pressing template 13 is installed in the installation table 12. The stepping motor 6 is started, and the stepping motor 6 drives the support rod 9 and the support column 10 to rotate. After the pressing template 13 rotates 90 degrees and stays on the inner bottom wall of the first groove 17 of the feeding support table 3, the injection port 18 injects materials into the die groove on the pressing film plate 13. After the injection is completed, the stepping motor 6 is started to drive the support rod 9 and the support column 10 to rotate 90 degrees. At this time, during the rotation process, the support rod 9 swings up and down through the convex block 8 and is shock-absorbed by the spring shock absorber 11. At this time, the powder in the pressing template 13 is flattened, and at the same time, the injection operation is performed on the next adjacent pressing template 13. Then, the stepping motor 6 drives the support rod 9 and the support column 10 to rotate 90 degrees. After continuing to flatten the powder, the pressing film plate 13 is moved to the inner bottom wall of the second groove 19 of the hot pressing support table 4. Subsequently, the hydraulic rod 20 is used to push the module 21 for hot pressing operation. The stepping motor 6 drives the support rod 9 and the support column 10 to rotate 90 degrees, and the pressing template 13 is moved to the unloading support table 5. And the abutting block 22 of the unloading support table 5 pushes the baffle 15 to rotate around the rotating shaft 14 and compresses the torsion spring 16. When the baffle 15 rotates completely open, the rough brake pads after pressing fall into the unloading groove 23 and are collected. The stepping motor 6 continues to drive the support rod 9 and the support column 10 to rotate 90 degrees. At this time, the abutting block 22 is separated from the baffle 15, and the baffle 15 is reset under the action of the torsion spring 16 to block the lower bottom side of the pressing film plate 13, and the baffle 15 is supported by the arc-shaped support plate 25.

[0022] The device drives the support rod 9 to rotate through the stepping motor 6. When the support rod 9 passes through the convex block 8, it swings up and down with the height amplitude of the convex block 8, and the powder material in the pressing template 13 is flattened through the bumps, thereby avoiding the consequences of uneven material distribution during hot pressing on the hot pressing support table 4, such as cracking, peeling off, and inability to brake. The arc-shaped support plate 25 supports the baffle to prevent the baffle 15 from falling off the pressing template 13.

[0023] As is known by common technical knowledge, the present invention can be implemented by other embodiments without departing from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
