Description

Technical Field

[0001] The invention relates to the technical field of brake pad production, and in particular to a brake pad pressing device. Background Art

[0002] Brake pads, also called brake leathers, are composed of a steel-cast backing steel component and a friction pad pressed on it. They are connected to the hydraulic system through the pin hole of the backing steel part. The hydraulic system controls the brake pads and the brake disc on the wheel hub to achieve the braking effect.

[0003] In the laminating production process of brake pads, granular and powdered lining materials are combined with steel backings and pressed into a unified whole by heating and pressurizing. However, the traditional laminating device used to produce brake pads has a low degree of automation. The steel backing and lining materials need to be placed and added manually, and the cavity mold is composed of an upper mold and a lower mold. The specific processing process is as follows: the steel backing needs to be placed in the lower mold first, and then the lining material is added after the upper mold is covered, and finally the pressing mold is used for pressing and forming. After the laminating of the brake pad is completed, the brake pad needs to be manually removed from the mold. This loading and unloading method is not only cumbersome, but also increases the labor cost, resulting in limited brake pad production efficiency. Therefore, a brake pad laminating device is proposed. Summary of the invention

[0025] In this embodiment, the mold feeding mechanism 2 includes a lower mold 21 and an upper mold 22, and two pairs of fixed blocks 23 are connected to the processing table 1, and each pair of fixed blocks 23 is connected to two parallel sliding rods 231, and the two sliding rods 231 on each pair of the fixed blocks 23 are respectively slidably connected to an upper slider 25 and a lower slider 24, and the two lower sliders 24 are respectively connected to the two sides of the lower mold 21, and the two upper sliders 25 are respectively connected to the two sides of the upper mold 22, and a plurality of penetrating steel back grooves 211 are opened on the lower mold 21, and a plurality of penetrating lining grooves 221 are opened on the upper mold 22.

[0026] In this embodiment, a first cylinder 26 is installed on the rear side of the processing table 1, and the movable end of the first cylinder 26 is connected to the upper mold 22. A first spur rack 28 is connected to the bracket 12. The upper slider 25 close to the first spur rack 28 is rotatably connected to a gear 27, and the lower slider 24 close to the first spur rack 28 is connected to a second spur rack 29. The gear 27 is meshed with the first spur rack 28 and the second spur rack 29 at the same time. The gear 27, the first spur rack 28 and the second spur rack 29 together form a stroke amplification mechanism. When the first cylinder 26 pushes the upper mold 22 to slide, the sliding distance of the lower mold 21 is twice the sliding distance of the upper mold 21.

[0027] In this embodiment, the bottom surface of the lower mold 21 is in contact with the upper surface of the processing table 1 , and the top surface of the lower mold 21 is in contact with the bottom surface of the upper mold 22 .

[0028] In this embodiment, the processing table 1 is provided with a feed opening 3 located directly below the bracket 12, and slide grooves are provided on both sides of the feed opening 3. A baffle 31 is provided at the feed opening 3, and slide bars 32 are connected to both sides of the baffle 31. The slide bars 32 on both sides of the baffle 31 are slidably connected to the slide grooves on both sides of the feed opening 3. A second cylinder 33 is installed on the bottom surface of the processing table 1, and a connecting block 34 is connected to the bottom surface of the baffle 31. The movable end of the second cylinder 33 is connected to the connecting block 34. A material receiving mechanism can be provided at the bottom of the processing table 1 located at the feed opening 3 to receive the brake pad that falls after lamination.

[0029] In this embodiment, the lining groove 221 of the upper mold 22 has the same shape as the die 14. After the first cylinder 26 pulls the upper mold 22 to slide so that the lining groove 221 is aligned with the die 14 up and down, the steel back groove 211 on the lower mold 21 is also overlapped and aligned with the lining groove 221.

[0030] In this embodiment, a lining quantitative feeder 15 is installed on the processing table 1 and located in front of the bracket 12. The lining quantitative feeder 15 can replace manual work to quantitatively add lining to the lining groove 221 in the upper mold 22 for pressing into a friction lining.

[0031] The working process and principle of the present invention are as follows:

[0032] When in use, the first cylinder 26 is turned on to push the upper mold 22 to slide. Under the transmission of the stroke amplification mechanism composed of the gear 27, the first spur rack 28 and the second spur rack 29, the lower mold 21 will also slide and the sliding distance is twice that of the upper mold 22, so that the originally aligned lining groove 221 and the steel back groove 211 are separated. After the lining groove 221 on the lower mold 22 slides to the lining quantitative feeder 15, the bottom of the lining groove 221 is the upper plane of the lower mold 21 as the bottom, and the lining quantitative feeder 15 The work is opened to add lining material to the lining groove 221 in a quantitative manner. At the same time, the worker puts the steel back into the steel back groove 211, which can realize the addition of lining material and the placement of steel back at the same time, saving loading time. After that, the first cylinder 26 is opened again to pull back and pull the upper mold 22 and the lower mold 21 back to their original positions. At this time, the steel back groove 211 is realigned with the lining groove 221 containing lining material with the baffle 31 as the bottom and carrying the steel back. Then the hydraulic cylinder 13 is opened to make the die 14 press down to press the lining into a friction lining and adhere it to the steel back to form a brake pad.

[0033] After the pressing is completed, the second cylinder 33 is turned on to pull the baffle 31 back to make the bottom of the steel back groove 211 on the lower mold 21 empty. At this time, the pressing die 14 is continued to be controlled to press down to push the pressed brake pad downward out of the mold to achieve rapid demolding of the product, which not only effectively improves the blanking efficiency, but also reduces a lot of labor and reduces labor costs.
