Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts processing equipment, specifically to a device for heat treatment of clutch plates. Background Technology

[0002] Clutch discs are composite materials whose primary function is friction, while also requiring structural performance. Automotive friction materials are mainly used to manufacture brake friction pads and clutch discs. During the production and processing of clutch discs, heat treatment is typically required.

[0003] Patent CN219174563U discloses a heat treatment device for clutch disc processing, including a heat treatment chamber with a heater fixedly installed inside. A U-shaped support base is fixedly connected to the bottom of the heat treatment chamber. An energy-saving inlet / outlet assembly is provided on the heat treatment chamber, including an insulated inlet / outlet pipe that penetrates and is embedded in the outer wall of the bottom of the heat treatment chamber. A matching disc-holding mesh cylinder is provided above the insulated inlet / outlet pipe, and multiple clutch discs are placed inside the disc-holding mesh cylinder. A lower insulated sealing plate is provided inside the insulated inlet / outlet pipe and is slidably and sealingly connected to it. Through the setting of the energy-saving inlet / outlet assembly, the heat treatment device ensures that the heat treatment chamber remains sealed during the process of removing clutch discs from the heat treatment chamber and placing clutch discs into the heat treatment chamber, thereby greatly reducing heat loss, significantly reducing energy waste, and greatly improving energy-saving and environmental protection performance.

[0004] When the plate-holding mesh cylinder moves up and down with the upper and lower insulation sealing plates, the top opening faces directly upwards. The clutch plate is supported only by the support block at the bottom, lacking a limiting structure for the top surface. If vibration occurs during the operation of the device or the lifting speed is uneven during operation, the clutch plate may slip off from the opening, causing damage to the workpiece or contaminating the internal environment of the heat treatment chamber.

[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] Please see Figure 1-5The present invention discloses a device for heat treatment of clutch plates, comprising a heat treatment chamber 1, a bearing assembly, and a limiting assembly. The bearing assembly includes a base plate 2, a base 3, and a bracket 9. The bottom of the heat treatment chamber 1 is provided with a slot. The base plate 2 is located at the lower end of the heat treatment chamber 1. The base 3 is fixed to the upper end of the base plate 2 and passes through the slot. The inner wall of the slot is provided with multiple limiting slots. The periphery of the base 3 is provided with multiple side blocks 4 that cooperate with the limiting slots. The vertical cylinder 5 is fixed to the middle part of the base 3. The bracket 9 is fixed on the vertical cylinder 5, and the vertical cylinder 5 is provided with a threaded hole 6. A first motor 11 is provided below the heat treatment chamber 1. The output end of the first motor 11 is provided with a first threaded rod 12 that is inserted into the threaded hole 6.

[0026] The limiting assembly includes a second motor 13 and a top plate 15. The second motor 13 is fixed above the heat treatment chamber 1. The lower end of the top plate 15 is provided with a plurality of vertical rods 14 that are inserted into the heat treatment chamber 1. The lower end of the vertical rods 14 is provided with a limiting plate 17 that can be inserted into the bracket 9. The output end of the second motor 13 is provided with a second threaded rod 16 that penetrates the top plate 15 and is threadedly connected to the top plate 15.

[0027] Loading and Preheating Preparation: Before heat treatment, the operator neatly places multiple clutch plates in the bracket 9, allowing the bracket 9 to enter the heat treatment chamber 1. At this time, the entire device is in its initial state; neither the first motor 11 nor the second motor 13 is started, and the limit plate 17 is located above the bracket 9, not in contact with the clutch plates. The heating equipment inside the heat treatment chamber 1 can be preheated in advance to prepare for subsequent heat treatment work.

[0028] Heat treatment process: Once everything is ready, the base 3 is positioned precisely in the empty slot at the bottom of the heat treatment chamber 1. The designated heating equipment is then activated to heat treat the clutch discs inside the chamber. During this process, the load-bearing components and the limiting components remain stationary to ensure that the clutch discs complete the heat treatment process in a stable environment.

[0029] In this embodiment, both the first motor 11 and the second motor 13 are servo motors.

[0030] In this embodiment, the multiple limiting plates 17 are the same size and are all fan-shaped structures.

[0031] Unloading Operation: After the clutch disc heat treatment is completed, the unloading process begins. First, the second motor 13 is started, and the second threaded rod 16 at the output end of the second motor 13 begins to rotate. Since the second threaded rod 16 is threadedly connected to the top plate 15, the top plate 15 will move downwards as the second threaded rod 16 rotates. The vertical rod 14 at the lower end of the top plate 15 and the limiting plate 17 fixed at the lower end of the vertical rod 14 will also descend synchronously until the limiting plate 17 contacts the clutch disc in the bracket 9. Next, the first motor 11 is started and the second motor 13 is started. The first threaded rod 12 at the output end of the first motor 11 begins to rotate. Since the first threaded rod 12 is inserted into the threaded hole 6 in the vertical cylinder 5, the vertical cylinder 5 will descend as the first threaded rod 12 rotates, thereby driving the base 3 and the bracket 9 to descend together. Because both the first motor 11 and the second motor 13 are servo motors, the speed can be precisely controlled, so the descent speed of the vertical cylinder 5 is the same as the descent speed of the limiting plate 17. During the descent, the fan-shaped limiting plate 17 of the same size can effectively limit the processed clutch discs in the bracket 9, preventing the clutch discs from shifting or falling off when the bracket 9 descends. When the bracket 9 descends below the heat treatment chamber 1, the operator can easily unload the clutch discs in the bracket 9.

[0032] In this embodiment, the upper ends of the two side blocks 4 are provided with support plates 7, the top ends of the two support plates 7 are connected by a connecting plate 8, and the connecting plate 8 is provided with a through hole through which the vertical rod 14 passes. The two ends of the connecting plate 8 are fixed to the top ends of the support plates 7 by screws.

[0033] Structural stability assurance: Throughout the operation, the structural design of the load-bearing components provides stable support. The side blocks 4 on the periphery of the base 3 cooperate with the limiting grooves on the inner wall of the empty slot of the heat treatment chamber 1. When the bracket 9 is raised or lowered, the side blocks 4 slide along the limiting grooves, ensuring the stability of the bracket 9 during the raising and lowering process. At the same time, the support plates 7 at the upper ends of the two side blocks 4 are connected by connecting plates 8, and the connecting plates 8 are provided with through holes through which the vertical rod 14 passes. During the descent of the vertical rod 14, the connecting plates 8 can provide a certain guiding effect, further improving the stability of the bracket 9 during raising and lowering.

[0034] High-efficiency unloading and anti-drop design: This device, through a unique limiting component design, allows the limiting plate 17 to accurately limit the clutch disc within the bracket 9 during unloading. Compared to traditional devices, this effectively avoids the problem of the clutch disc slipping during unloading due to the lack of a top limiting structure, reducing the risk of workpiece damage and internal contamination of the heat treatment chamber 1, and greatly improving the safety and efficiency of unloading.

[0035] The stable lifting structure of the bracket 9: the cooperation between the load-bearing components and the limiting components, as well as the structural design of the side block 4 and the limiting groove, and the support plate 7 and the connecting plate 8, ensure the stability of the bracket 9 during the lifting process. This stability not only helps to improve the accuracy of unloading, but also avoids the impact of bracket 9 shaking on the heat treatment effect of the clutch plate during heat treatment, thus ensuring the consistency of product quality.

[0036] In this embodiment, a support plate 10 is fixedly installed below the heat treatment box 1, and the first motor 11 is fixed at the lower end of the support plate 10.

[0037] A support plate 10 is provided below the heat treatment chamber 1 for mounting the first motor 11, which makes the installation of the first motor 11 more convenient and also facilitates routine maintenance and repair of the first motor 11. This design optimizes the overall structural layout of the device and improves the maintainability of the equipment.
