Description

Technical Field

[0001] This utility model belongs to the field of brake pad manufacturing technology, specifically relating to a tooling for pressing and heating sound-absorbing sheets on brake pads. Background Technology

[0002] With the rise and development of electric vehicles, more stringent requirements have been placed on brake pad noise. To improve brake pad noise, various types of noise-absorbing adhesives have emerged, such as acrylic rubber, nitrile rubber (NBR), vulcanized rubber, and silicone. However, the heat-pressing process requirements for different materials of noise-absorbing adhesives also differ. According to the existing information on different materials of noise-absorbing pads, it has been found that some brake pads require a certain temperature on the steel back paint surface, some require a certain heat-pressing time and pressure, and some require the paint surface treatment to meet certain dyne requirements (such as passing a dyne pen test of at least 46). This makes the original heat-pressing equipment and tooling somewhat unsuitable, so it is necessary to optimize and improve the existing heat-pressing equipment and tooling. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this utility model proposes a tooling for pressing and heating sound-absorbing sheets on brake pads, which improves efficiency, thereby increasing the overall production cycle and reducing labor intensity.

[0004] The technical solution adopted in this utility model is:

[0005] A tooling for pressing silencing pads on brake pads includes a pressing platform with several pressing devices arranged in a row on the platform. The front side of the first pressing device is provided with a brake pad input chain plate, and the rear side of the last pressing device is provided with a brake pad output chain plate. The end of the brake pad input chain plate is provided with a blocking cylinder for positioning the brake pad. One side of the brake pad input chain plate is provided with several shifting fork cylinders that can move the brake pads to the pressing platform below the corresponding pressing devices. The outer side of the last shifting fork cylinder is provided with a pushing cylinder for pushing the pressed brake pads to the brake pad output chain plate.

[0006] Furthermore, the pusher cylinder and the shift fork cylinder move synchronously along the direction of brake pad movement.

[0007] Furthermore, the number of the shift fork cylinders is the same as the number of the heat pressing devices.

[0008] Furthermore, the fork cylinder is equipped with a fork fixture for lifting or lowering the brake pads.

[0009] Furthermore, the blocking cylinder is provided with a blocking block to block or release the brake pads.

[0010] Furthermore, the pusher cylinder is equipped with a pusher plate that pushes the brake pads to move.

[0011] Furthermore, the brake pad input chain plate is provided with a first sensor for sensing the brake pads, and a clamping cylinder is provided at the first sensor to prevent or allow the brake pads to enter the brake pad input chain plate corresponding to the shift fork cylinder.

[0012] Furthermore, a second sensor for sensing the brake pad's position is provided on one side of the blocking cylinder.

[0013] Furthermore, several of the aforementioned heat-pressing devices are configured to press down synchronously.

[0014] Furthermore, each of the heat pressing devices is equipped with a thickness sensor for measuring the thickness of the brake pads.

[0015] The beneficial effects of this utility model are:

[0016] 1. In order to cope with the increased single-piece pressing time while meeting the T-Pull requirements, multiple pressing devices are set up for simultaneous pressing. Thus, under a certain pressing time, multiple brake pads can be pressed at one time, which improves efficiency, thereby increasing the overall production cycle and reducing labor intensity.

[0017] 2. Each heat press is equipped with a thickness sensor, which will sound an alarm when the detected size exceeds the range, in order to prevent the sound-absorbing sheet from being missing or over-assembled. Attached Figure Description

[0025] See Figure 1-3This embodiment provides a tooling for pressing and heating the sound-absorbing pads on brake pads, including a pressing platform 1. The pressing platform 1 is provided with a plurality of pressing devices 2 arranged in a row. The front side of the first pressing device 2 is provided with a brake pad input chain plate 3, and the rear side of the last pressing device 2 is provided with a brake pad output chain plate 4. The end of the brake pad input chain plate 3 is provided with a blocking cylinder 6 for positioning the brake pad 5. The side of the brake pad input chain plate 3 is provided with a plurality of shift fork cylinders 7 that can move the brake pad 5 to the pressing platform 1 below the corresponding pressing device 2. The outer side of the last shift fork cylinder 7 is provided with a pushing cylinder 8 for pushing the pressed brake pad 5 to the brake pad output chain plate 4.

[0026] In this embodiment, the pusher cylinder 8 and the shift fork cylinder 7 move back and forth synchronously along the moving direction of the brake pad 5.

[0027] In this embodiment, the number of shifting fork cylinders 7 is the same as the number of pressing devices 2. Preferably, three shifting fork cylinders 7 and three pressing devices 2 are provided, because three pieces are pressed at a time, and with a fixed pressing time, the production cycle per piece is about 1 / 3 of the original, thereby improving efficiency.

[0028] In this embodiment, the fork cylinder 7 is equipped with a fork fixture 9 for lifting or lowering the brake pad 5. The blocking cylinder 6 is equipped with a blocking block 10 for blocking or releasing the brake pad 5. The pushing cylinder 8 is equipped with a pushing plate 11 for pushing the brake pad 5 to move.

[0029] In this embodiment, a first sensor 12 for sensing the brake pad 5 is provided on the brake pad input chain plate 3. A clamping cylinder 13 is provided at the first sensor 12 to prevent or allow the brake pad 5 to enter the brake pad input chain plate 3 corresponding to the shift fork cylinder 7. A second sensor 14 for sensing the brake pad 5 to be in position is provided on one side of the blocking cylinder 6.

[0030] In this embodiment, several of the heat pressing devices 2 are arranged to press down synchronously. Each heat pressing device 2 is equipped with a thickness sensor 15 for measuring the thickness of the brake pad 5.

[0031] In this embodiment, both the brake pad input chain plate 3 and the brake pad output chain plate 4 are driven by corresponding drive motors. The heat pressing device 2 described in this embodiment is an existing device.

[0032] In this embodiment, the blocking cylinder 6, shift fork cylinder 7, pusher cylinder 8, clamping cylinder 13, first sensor 12, second sensor 14, blocking cylinder 6, etc., all use common components.

[0033] Through experimentation, it was found that to meet the requirement of T-Pull≥3N / mm, the surface treatment must first meet the requirements of a 46-dyne pen test, which necessitates increasing the heat pressing time per piece, thus reducing production efficiency. To address this efficiency issue, this invention incorporates multiple heat pressing devices for simultaneous heat pressing, with a temperature set up to 180℃.

[0034] When this utility model is in operation, when the first sensor 12 senses the brake pad 5, the clamping cylinder 13 clamps the brake pad 5, preventing the brake pad 5 from entering the brake pad input chain plate 3 corresponding to the shift fork cylinder 7. After clamping cylinder 13 opens, three brake pads 5 are conveyed to blocking cylinder 6. Clamping cylinder 13 clamps the fourth brake pad, awaiting the next release of the release brake pad 5. After the second sensor 14 senses the brake pad 5, three fork-pulling cylinders 7 and one pusher cylinder 8 extend, and the fork-pulling fixture 9 lifts the corresponding brake pad 5. The blocking cylinder 6 retracts, and the three fork-pulling cylinders 7 and one pusher cylinder 8 move synchronously. The pusher plate 11 on the pusher cylinder 8 pushes the three brake pads pressed by the heat pressing device 2 to the brake pad output chain plate 4. At the same time, the three fork-pulling cylinders 7 move the brake pads 5 sequentially to the bottom of the corresponding heat pressing device 2. After they are in place, the three fork-pulling cylinders 7 and one pusher cylinder 8 retract and move back to their original positions to continue lifting and conveying the next batch of brake pads 5. At this time, the heat pressing device 2 presses down simultaneously. The heat pressing time can be 2-10 seconds, and the temperature can be 100-180℃. As the three shifting fork cylinders 7 and the one pushing cylinder 8 move back to their original positions, the clamping cylinder 13 can release the brake pads 5. After the heat pressing device 2 has finished pressing, the shifting fork cylinders 7 and the pushing cylinder 8 continue to operate to feed and push the brake pads.

[0035] To address the increased pressing time per piece while meeting T-Pull requirements, this invention employs multiple pressing devices for simultaneous pressing. This allows for the pressing of multiple brake pads at once within a given pressing time, improving efficiency, increasing overall production cycle time, and reducing labor intensity. Each pressing device is equipped with a thickness sensor that triggers an alarm when the detected dimension exceeds the range, preventing the omission or over-assembly of silencer pads.
