Description

Technical Field

[0001] This utility model relates to the field of brake pad preparation technology, specifically to a mesh belt sintering furnace for preparing copper-based powder metallurgy brake pad materials. Background Technology

[0002] With the advancement of technology, the speed of high-speed railways has been continuously improved, and the operating conditions of their braking devices have become increasingly demanding. People require the braking devices to stop the high-speed train in a short time. This causes the huge kinetic energy of the high-speed train to be converted into frictional heat energy of the brake pads. The surface of the friction pair will rise sharply, affecting the friction coefficient of the friction material and reducing the safety and reliability of the high-speed train.

[0003] During the sintering and heating process, existing mesh belt sintering furnaces will drip carbon deposits and nodules onto the inner surface of the furnace chamber, causing unevenness in the furnace chamber. Prolonged scraping of the conveyor mesh belt body can easily lead to breakage of the conveyor mesh belt body.

[0004] To overcome the above-mentioned defects, the prior art (Chinese patent publication number: CN114577022B, application date: 2023-11-28) discloses a high-stability mesh belt sintering furnace, including a sintering furnace body, a cooling box, and a conveyor mesh belt assembly. A transmission rod is movably arranged on the inner side wall of the sintering furnace body, and an abutment roller is rotatably arranged on the outer side wall of the transmission rod at its middle position. A mounting frame is rotatably arranged on the outer side wall of the transmission rod via a bearing, and the abutment roller is located inside the mounting frame. Mounting rollers are provided on both sides of the mounting frame. Each side plate is equipped with a scraper blade at its bottom. This invention utilizes a transmission rod, mounting frame, and scraper blade in coordination. When the transmission rod moves the contact roller and mounting frame, it moves the scraper blade below the side plate to remove carbon deposits and nodules dripping from the bottom of the sintering furnace body. This prevents the furnace from becoming uneven due to carbon deposits and nodules, and avoids prolonged scraping of the conveyor belt, which could cause breakage. Cleaning can be performed without disassembling the entire conveyor belt, making it convenient to use.

[0005] While the above design can solve the aforementioned problems, the conveyor belt design is not stable enough when stable material conveying is required. During a single high-weight conveying process, the conveyor belt will dent downwards, causing the material to tip over and slip, resulting in insufficient conveying stability. At the same time, during the sintering process, due to the thick accumulation of material, the heating of the upper layer and the interior is not uniform, resulting in a poor final product quality, affecting practical use, and reducing the processing efficiency of the equipment. Utility Model Content

[0006] The purpose of this invention is to provide a mesh belt sintering furnace for preparing copper-based powder metallurgy brake pad materials, in order to solve the problems mentioned in the background art, such as insufficient stability of the conveyor belt design when stable raw material conveying is required. During the one-time high-weight conveying process, the conveyor belt will sink downward, causing the raw material to tip over and slip, resulting in insufficient conveying stability. At the same time, during the sintering process, due to the thick accumulation of raw materials, the heating of the upper layer and the interior is not uniform, resulting in poor final product quality, affecting practical use, and reducing the processing efficiency of the equipment.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mesh belt sintering furnace for preparing copper-based powder metallurgy brake pad materials, comprising a support and fixing base and a sintering mesh belt. The support and fixing base has sliding frames installed on its left and right sides, and the sliding frames have internal meshing transmission mechanisms for rotating a second dispersive lever. The meshing transmission mechanism includes a fixed drive motor, which is fixedly installed on the side of the support and fixing base. The sliding frames have internal sealing and heat-insulating frames that completely cover the top of the support and fixing base. The inner surface of the support and fixing base has a mating and fixing inner groove, and the inner groove has an elastic sliding mechanism for pressing a second auxiliary rotating frame.

[0008] Furthermore, the elastic sliding mechanism includes a first driving rod, which is fixedly installed on the outer surface of the output end of the fixed drive motor. The first driving rod is rotatably installed inside the support base, and a sintered mesh belt is installed on the outer surface of the first driving rod.

[0009] Furthermore, a limiting stacking plate is installed above the sintering mesh belt, and the limiting stacking plate is fixedly installed inside the support fixing seat. The second auxiliary rotating frame is fixedly installed on the lower surface of the limiting stacking plate, and the lower end of the second auxiliary rotating frame is continuously in contact with the sintering mesh belt. An interlocking recycling ring is installed inside the docking fixing inner groove, and the first auxiliary rotating frame is installed inside the interlocking recycling ring.

[0010] Furthermore, a series transmission belt is installed on the outer surface of the output end of the fixed drive motor, and a first dispersing lever is installed inside the sealed insulation frame. The first dispersing lever is rotatably installed inside the two sides of the sealed insulation frame, and a first meshing gear is installed at the side end of the first dispersing lever.

[0011] Furthermore, the first meshing gear and the first dispersing lever are integrated into one piece, and the second meshing gear is installed inside the sealed insulation frame. The second dispersing lever is installed on the side of the second meshing gear and is rotatably installed inside the sealed insulation frame. Moreover, the second dispersing lever and the second meshing gear are integrated into one piece.

[0012] Furthermore, the first meshing gear and the second meshing gear mesh with each other, and the rotation trajectories of the first dispersing lever and the second dispersing lever both contact the sintering mesh belt. The outer surfaces of the first meshing gear and the outer surfaces of the second meshing gear contact each other to form a meshing structure. A heating processing plate is installed above the sealing and heat preservation frame, and an inclined feed port is installed above the sealing and heat preservation frame.

[0013] Furthermore, a compression spring is installed on the outer surface of the first auxiliary rotating frame, and the end of the compression spring abuts against the top of the fitting recycling ring. Two sets of limiting stacking plates are symmetrically installed about the center point of the sintering mesh belt, and the sintering mesh belt and the outer surface of the limiting stacking plates are in close contact with each other.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the raw material needs to be stably conveyed, after the raw material is placed on the sintering mesh belt, it will be directly conveyed forward until it is processed by the heating processing plate. The limiting stacking plates on both sides will limit the raw material on both sides to ensure that it will not fall. In addition, the first auxiliary rotating frame will support the lower end of the sintering mesh belt due to the upward push of the compression spring. This design improves the stability of the conveying process. The raw material will not tilt or slip during the conveying of heavy materials, thus improving the conveying efficiency of the equipment.

[0015] Furthermore, the start of the fixed drive motor will drive the first dispersing lever through the series transmission belt, so that the first dispersing lever rotates continuously and in the process of rotation, it will continuously move and disperse the raw materials on the sintering mesh belt. Moreover, the first dispersing lever drives the second dispersing lever again through the first meshing gear, which ensures that the raw materials receive a more comprehensive heating effect and improves processing efficiency.

[0016] Furthermore, the sealed insulation rack is slidably installed inside the sliding racks on both sides, allowing for quicker disassembly and cleaning of the equipment's interior. The sealed insulation rack and the inclined feed inlet are designed as a single unit, enabling rapid material conveying. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-6 The present invention provides the following technical solution: a mesh belt sintering furnace for preparing copper-based powder metallurgy brake pad materials, comprising a support and fixing base 1 and a sintering mesh belt 4. Two sliding frames 5 are installed on the left and right sides of the support and fixing base 1, and a meshing transmission mechanism for rotating a second dispersive lever 18 is installed inside the sliding frames 5. The meshing transmission mechanism includes a fixed drive motor 2, which is fixedly installed on the side of the support and fixing base 1. A sealing and heat-insulating frame 8 is installed inside the sliding frames 5, and the sealing and heat-insulating frame 8 completely covers the top of the support and fixing base 1. A docking and fixing inner groove 11 is opened on the inner surface of the support and fixing base 1, and an elastic sliding mechanism for pressing a second auxiliary rotating frame 17 is installed inside the docking and fixing inner groove 11.

[0026] like Figure 2 , Figure 3 , Figure 4The technical solution shown addresses the problem of insufficient stability in the conveyor belt design during stable raw material transport operations. Specifically, it discloses that the conveyor belt can sag during high-weight transport, causing the raw material to tip over and slip, resulting in insufficient transport stability. The solution includes: a series transmission belt 6 mounted on the outer surface of the output end of the fixed drive motor 2; a first dispersing lever 16 installed inside the sealed insulation frame 8; the first dispersing lever 16 rotatably mounted inside both sides of the sealed insulation frame 8; and a first meshing gear 15 mounted on the side end of the first dispersing lever 16. The first meshing gear 15 and the first dispersing lever 16 are integrated into a single unit. The sealing and heat preservation frame 8 is equipped with a second meshing gear 19. A second dispersing lever 18 is installed on the side of the second meshing gear 19. The second dispersing lever 18 is rotatably installed inside the sealing and heat preservation frame 8. The second dispersing lever 18 and the second meshing gear 19 are designed as a single unit. The first meshing gear 15 and the second meshing gear 19 mesh with each other. The rotation trajectories of the first dispersing lever 16 and the second dispersing lever 18 both contact the sintering mesh belt 4. The outer surface of the first meshing gear 15 and the outer surface of the second meshing gear 19 contact each other to form a meshing structure. A heating processing plate 10 is installed above the sealing and heat preservation frame 8. An inclined feed port 9 is installed above the sealing and heat preservation frame 8.

[0027] When the raw materials need to be continuously agitated and dispersed during the conveying process, the fixed drive motor 2, which is fixedly installed on the side of the support base 1, starts working and drives the series transmission belt 6, which is attached to the outer surface. Inside the series transmission belt 6, on the other side, a first dispersing lever 16 is installed. Since the first dispersing lever 16 is rotatably installed inside the sliding frames 5 on both sides, it rotates stably in a circular motion with the drive of the series transmission belt 6. The rotation trajectory of the first dispersing lever 16 continuously contacts the raw materials conveyed above the sintering mesh belt 4, continuously dispersing them. When the second dispersing lever 18 rotates, the outer surface... The fixedly installed second meshing gear 19 will rotate synchronously. While the second meshing gear 19 is rotating, it will mesh with the first meshing gear 15 that is in contact with the outside and drive it. Since the second meshing gear 19 is also rotatably installed inside the sealed insulation frame 8, the second meshing gear 19 will continuously rotate as driven by the meshing motion. At the same time, the second dispersing lever 18 fixedly installed at the center position will rotate synchronously, so that the raw materials will be more finely dispersed, ensuring higher processing efficiency. In addition, the inclined feed port 9 above the sealed insulation frame 8 and connected to its interior makes it easier to transport and process the raw materials.

[0028] Example 2: Figure 2 , Figure 3 , Figure 4The technical solution shown addresses the problem that during sintering, uneven heating between the upper and inner layers due to thick raw material accumulation leads to poor final product quality, affecting practical use and reducing equipment processing efficiency. The solution discloses an elastic sliding mechanism comprising a first drive rod 3, which is fixedly mounted on the outer surface of the output end of a fixed drive motor 2. The first drive rod 3 is rotatably mounted inside a support base 1, and a sintering mesh belt 4 is mounted on the outer surface of the first drive rod 3. A limiting stacking plate 7 is mounted above the sintering mesh belt 4 and fixedly mounted on the support base 1. Inside the fixed base 1, the second auxiliary rotating frame 17 is fixedly installed on the lower surface of the limiting stacking plate 7, and the lower end of the second auxiliary rotating frame 17 is continuously in contact with the sintering mesh belt 4. The inner groove 11 of the docking is equipped with a fitting recycling ring 12, and the inner groove 12 of the fitting recycling ring is equipped with a first auxiliary rotating frame 13. The outer surface of the first auxiliary rotating frame 13 is equipped with a compression spring 14, and the end of the compression spring 14 abuts against the top of the fitting recycling ring 12. The limiting stacking plate 7 is symmetrically installed with two sets of fittings about the center point of the sintering mesh belt 4, and the sintering mesh belt 4 is in contact with the outer surface of the limiting stacking plate 7.

[0029] When the raw material enters the support base 1 through the inclined feed port 9, it falls directly onto the sintering mesh belt 4. When the fixed drive motor 2 starts, the front output end drives the first drive rod 3 to rotate, causing the sintering mesh belt 4 outside the first drive rod 3 to be continuously conveyed. When the raw material falls onto the sintering mesh belt 4, it slides and spreads to the left and right. At this time, the raw material will come into contact with the limiting stacking plates 7 installed on the left and right sides of the inner surface of the support base 1. Because the ends of the limiting stacking plates 7 are in continuous contact with the sintering mesh belt 4, the raw material is restricted and conveyed stably. At the same time, when the sintering mesh belt 4 moves, its upper surface will be in contact with the second auxiliary rotating frame 17. The sintering mesh belt 4 continues to be bonded and rotated. Since the second auxiliary rotating frame 17 is fixedly installed below the limiting stacking plate 7, the sintering mesh belt 4 will not deviate due to the upper restriction. When the sintering mesh belt 4 rotates, the lower surface will abut against the first auxiliary rotating frame 13. As the first auxiliary rotating frame 13 moves downward, it will slide into the fitting and recycling ring 12 fixedly installed inside the docking and fixing inner groove 11. When the first auxiliary rotating frame 13 moves downward, the compression and shrinking spring 14 fitted on the outer surface will be resisted. When the compression and shrinking spring 14 abuts against the fitting and recycling ring 12, it will shrink, making the lower end of the sintering mesh belt 4 more supported and the raw material conveying more stable.
