[0001] The utility model relates to the technical field of hot pressing of brake pads, in particular to a feeding device for hot pressing automotive brake pads. Background Technique
[0002] Brake pads are the most critical safety parts in the braking system of vehicles. The braking effect is determined by the brake pads. The manufacturing process of brake pads has been continuously improved. While new materials for brake pads are being discovered, the change of manufacturing tools for brake pads is also inevitable. Brake pads are generally formed by hot pressing a steel plate and a friction material layer. Its process flow is mostly: powder mixing - hot forming - heat treatment - grinding - ablation - powder spraying - packaging, etc.
[0003] In the prior art, when hot pressing and forming, it is necessary to send the powder mixed friction material into the mold, and then perform hot pressing and forming. Before adding materials to the mold cavity in the mold, it is necessary to quantitatively put the powder into the feeding device in sequence, and then send the powdered friction material into the mold cavity of the mold through the feeding device, and then perform hot pressing and forming. Therefore, manual feeding is required for each hot pressing, which is rather troublesome, bringing a certain labor intensity to workers. At the same time, it is difficult for workers to put the same amount of powder into each material tank, so it will cause different densities of the produced brake pads, affecting the production quality. Therefore, there is room for improvement. Content of the Utility Model

The metering box is slidably connected to the movable box, and a plurality of metering cavities which are matched with the feeding ports and the discharging ports are provided in the metering box. A U-shaped card slot is fixedly provided around the discharging ports at the bottom of the movable box. The number of the feeding hoppers is matched with the number of the discharging ports, and a plurality of feeding hoppers are fixedly provided in a sliding plate.

[0023] As Figures 1-5 , in this embodiment, a feeding device for hot pressing automotive brake pads includes a storage box 1, a metering box 2, and a feeding hopper 3. A movable box 4 is provided at the bottom of the storage box 1. The top of the movable box 4 is communicated with the storage box 1 through a plurality of feeding ports 41, and a plurality of discharging ports 42 which are the same in number as the feeding ports 41 but are offset are provided at the bottom of the movable box 4. The metering box 2 is slidably connected in the movable box 4, and a plurality of metering cavities 21 which are matched with the feeding ports 41 and the discharging ports 42 are provided in the metering box 2. A U-shaped card slot 43 is fixedly provided around the discharging ports 42 at the bottom of the movable box 4. The number of the feeding hoppers 3 is matched with the number of the discharging ports 42, and a plurality of feeding hoppers 3 are fixedly provided in the sliding plate 31. The feeding hoppers 3 are movably clamped to the bottom of the movable box 4 through the sliding plate 31 and the U-shaped card slot 43, and the feeding hoppers 3 are docked with the discharging ports 42. An electric telescopic rod 22 is fixedly provided on one side of the metering box 2, and the electric telescopic rod 22 is fixedly installed on one side in the movable box 4.
[0024] Through the above technical solution, when it is necessary to introduce the powder friction material into the mold cavity in the forming mold, the feeding device is moved above the mold so that the feeding hopper 3 is aligned with the mold cavity of the mold. Then, the electric telescopic rod 22 pushes the metering box 2 to slide in the movable box 4, so that the metering cavity 21 in the metering box 2 is docked with the feeding port 41. At this time, the bottom of the metering cavity 21 in the metering box 2 is blocked by the bottom surface of the movable box 4, and at the same time, the metering box 2 blocks the feeding port 42 at the bottom of the movable box 4. The powder friction material is metered by the metering box 2. After the metering is completed, the electric telescopic rod 22 drives the metering box 2 to slide in the movable box 4, so that the bottom of the metering cavity 21 in the metering box 2 is docked with the feeding port 42, and at the same time, the metering box 2 blocks the feeding port 41 of the movable box 4 to prevent the powder friction material stored in the storage box 1 from leaking. The powder friction material metered by the metering cavity 21 falls into the feeding hopper 3 through the docked feeding port 42, and then is sent into the mold cavity of the mold. Through metering, the quality of the product can be effectively improved. The plurality of feeding hoppers 3 are fixedly connected by a sliding plate 31 and are connected to the bottom of the movable box 4 through a U-shaped card slot 43, which is convenient for replacement and maintenance.
[0025] Preferably: The distance between every two metering cavities 21 in the metering box 2 is greater than that between the feeding port 41 and the feeding port 42, and a staggered closure is formed between the feeding port 41 and the feeding port 42.
[0026] Through the above technical solution, the distance between the two metering cavities 21 in the metering box 2 is convenient for blocking the feeding port 41 or the feeding port 42. The staggering of the feeding port 41 and the feeding port 42 is convenient for the metering cavity 21 in the metering box 2 to block the feeding port 42 when the metering cavity 21 is docked with the feeding port 41, so as to facilitate the metering of the powder friction material by the metering cavity 21. At the same time, when the metering cavity 21 is docked with the feeding port 42, the metering box 2 will block the feeding port 41 to prevent the powder friction material in the storage box 1 from leaking into the movable box 4. The powder friction material after the metering in the metering cavity 21 falls into the feeding hopper 3 through the feeding port 42 for feeding work, ensuring the stability of the metering work.
[0027] Preferably: A handle 32 is provided on one side of the sliding plate 31 away from the U-shaped card slot 43, and one side of the sliding plate 31 away from the U-shaped card slot 43 is fixed to the bottom of the movable box 4 by bolts.
[0028] Through the above technical solution, the handle 32 facilitates the pulling of the sliding plate 31 in the U-shaped card slot 43, thereby facilitating the replacement of the feeding hopper 3. Then, the sliding plate 31 is fixed by bolts to improve the stability after installation.
[0029] Preferably: The shape of the feeding hopper 3 in the sliding plate 31 matches the mold cavity of the required feeding mold.
[0030] Through the above technical solution, since the sliding plate 31 is easy to replace, the hopper 3 is thus easy to replace. Cooperating with hoppers 3 of different shapes, it is convenient to feed materials into molds of different cavities, improving the convenience and applicability of the work.
