Description

Technical Field

[0001] This invention relates to the field of brake pad heat treatment technology, and in particular to a heat treatment apparatus for automobile brake pad production. Background Technology

[0002] Automotive brake pads are friction materials fixed to brake drums or brake discs that rotate with the wheels. The friction linings and friction blocks bear external pressure and generate friction to achieve the purpose of vehicle deceleration. Automotive brake pads are generally composed of steel plates, adhesive heat insulation layers and friction blocks. At the same time, the production of automotive brake pads requires the use of heat treatment equipment to cure the brake pads, ensure the temperature distribution of the brake pads, and improve product quality.

[0003] In existing brake pad heat treatment equipment, the brake pads are mostly laid flat on a shelf during the curing process. When the heat treatment equipment is working, the covered side and the brake pads that are far from the air outlet cannot be heated evenly, resulting in uneven heating of the brake pads. This requires the heat treatment equipment to operate continuously, affecting the heat treatment efficiency of the brake pads. This operation reduces production efficiency and also affects the overall quality of the brake pads. Therefore, this application provides a heat treatment device for automobile brake pad production to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a heat treatment device for automobile brake pad production to solve the problem that when existing heat treatment equipment is working, brake pads with a covered side and a distance from the air outlet are difficult to be heated evenly, resulting in uneven heating of the brake pads. This causes the heat treatment equipment to operate continuously, affecting the heat treatment efficiency of the brake pads. This operation reduces production efficiency and also affects the overall quality of the brake pads.

Multiple limiting brackets are fixedly connected to the surface of the load-bearing plate, and the limiting brackets are fixedly connected to the top of the groove provided on the surface of the load-bearing plate.

[0008] Optionally, a hollow frame is slidably connected to the surface of the support plate, and a stop block is fixedly connected to the bottom inner wall of the hollow frame. The stop block is cross-shaped, and multiple support plates are sleeved inside the hollow frame. Multiple elastic locking rods are fixedly connected to the top of the support plates.

[0009] Optionally, a cover plate is inserted into the top of the plurality of elastic locking rods, and a plurality of limiting rods are fixedly connected to the top of the support plate. The plurality of limiting rods and the plurality of elastic locking rods are alternately and fixedly connected to the top of the support plate.

[0010] Optionally, the bottom ends of the hollow frame are fixedly connected with pin slots, the pin slots are L-shaped frames, the inner wall of the pin slots is inserted with pin baffles, the pin baffles are inserted with multiple hollow frames, and the tops of multiple elastic locking rods are threaded with knobs.

[0011] Optionally, the auxiliary top contact assembly includes a sleeve inserted into the surface of the limiting rod, a spherical adsorption chamber fixedly connected to the outer surface of the sleeve, the interior of the spherical adsorption chamber being a hollow sphere, and a side door fixedly connected to the end of the spherical adsorption chamber.

[0012] Optionally, a fixed seat is fixedly connected inside the spherical adsorption chamber, and a cylinder is fixedly connected to the upper and lower inner walls of the fixed seat. A sliding seat is slidably connected to the surface of the cylinder, and a first spring is fixedly connected to the upper and lower ends of the sliding seat. The first spring is sleeved on the surface of the cylinder.

[0013] Optionally, a telescopic rod is fixedly connected to the end of the sliding seat, and an elastic ball is fixedly connected to the end of the telescopic rod. The elastic ball is made of heat-resistant material, and a second spring is sleeved on the surface of the telescopic rod. One end of the second spring is fixedly connected to the end of the sliding seat, and the other end of the second spring is fixedly connected to the surface of the elastic ball.

[0014] Optionally, the dynamic airflow guiding component includes a rotating fan plate fixedly connected to the output end of the circulating fan. The rotating fan plate is disposed inside the oven. A hollow tube is fixedly connected to the bottom of the rotating fan plate. A drive seat is fixedly connected to the bottom of the hollow tube.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting up a layered loading assembly, the cover plate and the support plate are combined with elastic locking rods and limiting rods to form a loading frame, changing the brake pads from being laid flat to being placed vertically, while ensuring the heat-receiving surface of the brake pads. Then, by using a hollow frame, multiple loading frames can be fixed through the hollow frame. Then, multiple hollow frames are placed in a carrier plate and placed in a heat treatment equipment to ensure that all surfaces of the brake pads can be heated.

[0018] By setting up an auxiliary top-contact assembly, the elastic ball installed on the spherical adsorption chamber can provide auxiliary top-contact to each brake pad placed in the loading frame, ensuring the brake pads are upright and reducing the impact of the brake pads on the heat treatment equipment, reducing the wear on the brake pads, and improving production quality. At the same time, activated carbon adsorption is placed inside the spherical adsorption chamber, which can purify the gases generated during heat treatment and avoid environmental pollution.

[0019] By setting up a dynamic airflow guiding component, the brake pads at the edge of the shelf can come into contact with the airflow, while the brake pads at the center of the shelf can also come into contact with the airflow delivered by the hollow tube. When the hollow tube rotates in conjunction with the drive seat, the arc-shaped metal plate can gather the airflow in the oven, forming a vortex to blow airflow onto the brake pads again, achieving uniform heating of the brake pads.

[0041] like Figures 1 to 12As shown, an embodiment of the present invention provides a heat treatment apparatus for automobile brake pad production, including an oven 1, an electrical box 2 fixedly connected to one end of the oven 1, a control panel 3 fixedly connected to the front end of the electrical box 2, a protective seat 4 fixedly connected to the top of the oven 1, a circulating fan 5 fixedly connected to the top of the protective seat 4, a honeycomb plate 9 fixedly connected to the inner wall of the oven 1, a support frame 10 fixedly connected to the surface of the honeycomb plate 9, a layered loading assembly 6 slidably connected to the surface of the support frame 10, the layered loading assembly 6 being used to load brake pads, and the layered loading assembly 6 being connected to the support frame 10; an auxiliary top contact assembly 7 being used to contact the brake pads placed in the layered loading assembly 6, and the auxiliary top contact assembly 7 being connected to the layered loading assembly 6; and a dynamic flow guiding assembly 8 being used to transport hot air to the surface of the brake pads, and the dynamic flow guiding assembly 8 being connected to the circulating fan 5.

[0042] As an implementation method in this embodiment, such as Figures 3 to 7As shown, the layered loading assembly 6 includes a support plate 61 slidably connected to the top of the support frame 10. The support plate 61 is open and U-shaped, and a groove is formed on the surface of the support plate 61. Multiple limiting brackets 63 are fixedly connected to the surface of the support plate 61, and the limiting brackets 63 are fixedly connected to the top of the groove formed on the surface of the support plate 61. A hollow frame 62 is slidably connected to the surface of the support plate 61. A stop block 69 is fixedly connected to the bottom inner wall of the hollow frame 62. The stop block 69 is cross-shaped. Multiple support plates 610 are sleeved inside the hollow frame 62. The top of the support plate 610 is fixedly connected to multiple elastic locking rods 65, and the top of the multiple elastic locking rods 65 is inserted with a cover plate 64. The top of the support plate 610 is also fixedly connected to multiple limiting rods 67. The multiple limiting rods 67 and the multiple elastic locking rods 65 are alternately fixedly connected to the top of the support plate 610. The bottom ends of the hollow frame 62 are fixedly connected to pin slots 68. The pin slots 68 are L-shaped frames. The inner wall of the pin slots 68 is inserted with pin baffles 611. The pin baffles 611 are inserted with the multiple hollow frames 62. The top of the multiple elastic locking rods 65 is threaded with a knob. 66. When the pin baffle 611 is inserted into the pin slot 68 at the bottom of the hollow frame 62, multiple hollow frames 62 are connected to the pin baffle 611. Then, the support plate 610 with the elastic locking rod 65 and the limiting rod 67 is placed at the bottom of the hollow frame 62. At this time, the support plate 610 is placed in the space enclosed by the cross-shaped stop block 69 and the hollow frame 62. Then, multiple auxiliary top contact components 7 are inserted into the limiting rod 67. Then, the cover plate 64 is inserted into the top of the elastic locking rod 65 and the limiting rod 67. After the connection is completed, the knob 66 ​​is turned. Complete the threaded connection with the elastic locking rod 65, and fix the cover plate 64 to form a carrying frame between the cover plate 64 and the support plate 610. Then, place the brake pads vertically from the top of the cover plate 64. After the brake pads are placed, slide the pin baffles 611 onto the support plate 61. At this time, the limit bracket 63 fixes the frame of the hollow frame 62. After all the pin baffles 611 are placed on the support plate 61, insert the multiple sets of support plates 61 with brake pads into the support frame 10 inside the oven 1.

[0043] As an implementation method in this embodiment, such as Figures 6 to 9As shown, the auxiliary top contact assembly 7 includes a sleeve 71 inserted into the surface of the limiting rod 67. A spherical adsorption chamber 72 is fixedly connected to the outer surface of the sleeve 71. The interior of the spherical adsorption chamber 72 is a hollow sphere. A side door 73 is fixedly connected to the end of the spherical adsorption chamber 72. A fixing seat 74 is fixedly connected to the interior of the spherical adsorption chamber 72. A cylinder 75 is fixedly connected to the upper and lower inner walls of the fixing seat 74. A sliding seat 76 is slidably connected to the surface of the cylinder 75. A first spring 77 is fixedly connected to the upper and lower ends of the sliding seat 76. 77 is fitted onto the surface of cylinder 75. A telescopic rod 78 is fixedly connected to the end of the sliding seat 76. An elastic ball 710, made of heat-resistant material, is fixedly connected to the end of the telescopic rod 78. A second spring 79 is fitted onto the surface of the telescopic rod 78. One end of the second spring 79 is fixedly connected to the end of the sliding seat 76, and the other end is fixedly connected to the surface of the elastic ball 710. When the brake pad enters from the top of the cover plate 64, the auxiliary top contact assembly 7 starts operating. As the brake pad moves downwards from the top of the cover plate 64... The upward thrust caused by the impact first causes each surface of the upright brake pad to make point contact with multiple elastic balls 710. Then, to mitigate the impact and avoid wear on the brake pad surface, the elastic balls 710 move under the thrust. Simultaneously, the second spring 79 retracts along with the telescopic rod 78, while the telescopic rod 78 moves the sliding seat 76 on the inner wall cylinder 75 of the fixed seat 74. At this time, the sliding seat 76 begins to float under the action of the first springs 77 at its upper and lower ends, thus mitigating the impact. The impact force from the brake pads is applied by the elastic ball 710, which continuously contacts the surface of the brake pads to prevent them from moving and causing wear and tear in the oven 1. The spherical adsorption chamber 72 can absorb the harmful gases generated during the heat treatment of the brake pads. When a batch of brake pads has finished heat treatment, the sleeve 71 fixedly connected inside the spherical adsorption chamber 72 can be slid off from the layered loading assembly 6. Then, the side chamber door 73 can be opened to replace the activated carbon inside the spherical adsorption chamber 72 before it can be reinstalled for the next operation.

[0044] As an implementation method in this embodiment, such as Figures 10 to 12As shown, the dynamic airflow guiding component 8 includes a rotating fan disc 81 fixedly connected to the output end of the circulating fan 5. The rotating fan disc 81 is disposed inside the oven 1. A hollow tube 82 is fixedly connected to the bottom of the rotating fan disc 81, and a drive seat 83 is fixedly connected to the bottom of the hollow tube 82. The drive seat 83 is rotatably connected to the bottom of the oven 1. Multiple air ducts 84 are inserted into the end of the hollow tube 82, and the multiple air ducts 84 are inserted into the hollow tube 82 at different angles. Connecting blocks 85 are fixedly connected inside the multiple air ducts 84, and arc-shaped metal plates 86 are fixedly connected to the ends of the multiple connecting blocks 85. The arc-shaped metal plates 86 are inclined at a certain angle and connected to the connecting blocks 85. When the drive seat 83, which is rotatably connected to the bottom of the oven 1, drives the air duct 84, which is fixedly connected to the top, to rotate, the air duct 84 is rotated. The hollow tube 82 rotates, and the rotating fan disc 81 connected to the top of the hollow tube 82 drives the airflow into the hollow tube 82. The airflow is then delivered through the hollow tube 82 to multiple air ducts 84 at different angles installed at the end of the hollow tube 82. The air ducts 84 then blow the airflow onto the brake pads on each layer of support frame 10. At the same time, as the drive seat 83 drives the hollow tube 82 to rotate, the connecting block 85 fixedly connected to the end of the air duct 84 drives the arc-shaped metal plate 86 to rotate in the same direction as the drive seat 83. As the multiple arc-shaped metal plates 86 rotate, the airflow inside the oven 1 forms a vortex, which continuously washes the brake pads inside the oven 1, making the brake pads heat up more evenly.

[0045] The working principle of the technical solution provided by this invention is as follows:

[0046] When using this device, first insert the pin baffle 611 into the pin slot 68 at the bottom of the hollow frame 62. At this time, multiple hollow frames 62 are connected to the pin baffle 611. Then, place the support plate 610 with the elastic locking rod 65 and the limiting rod 67 at the bottom of the hollow frame 62. At this time, the support plate 610 is placed in the space enclosed by the cross-shaped stop block 69 and the hollow frame 62. Then, insert multiple auxiliary top contact components 7 into the limiting rod 67. Then, insert the cover plate 64 into the top of the elastic locking rod 65 and the limiting rod 67. After completing the connection, rotate... Button 66 completes the threaded connection with the elastic locking rod 65, completing the fixation of the cover plate 64, so that the cover plate 64 and the support plate 610 form a carrying frame. Then, the brake pads are placed vertically from the top of the cover plate 64. After the brake pads are placed, the pin baffles 611 are slidably pushed onto the support plate 61. At this time, the limit bracket 63 fixes the frame of the hollow frame 62. At the same time, after all the pin baffles 611 are placed on the support plate 61, the multiple sets of support plates 61 with brake pads are inserted into the support frame 10 inside the oven 1.

[0047] When the brake pads enter from the top of the cover plate 64, the auxiliary contact assembly 7 starts to operate. As the brake pads move downwards from the top of the cover plate 64, the vertical surfaces of the brake pads first make point contact with multiple elastic balls 710. Then, after the elastic balls 710 are subjected to the pushing force, in order to mitigate the impact and avoid wear on the brake pad surface, the second spring 79 retracts along with the telescopic rod 78 during the pushing motion. Simultaneously, the telescopic rod 78 drives the sliding seat 76 to move on the cylinder 75 inside the fixed seat 74. At this time, the sliding seat 76... The brake pads begin to float under the action of the first spring 77 at the upper and lower ends, relieving the impact force from the brake pads. Then, the elastic ball 710 continuously contacts the surface of the brake pads to prevent the brake pads from moving and causing bumps and wear in the oven 1. The spherical adsorption chamber 72 can absorb the harmful gases generated during the heat treatment of the brake pads. When a batch of brake pads has finished heat treatment, the sleeve 71 fixedly connected inside the spherical adsorption chamber 72 can be slid off from the layered loading assembly 6. Then, the side chamber door 73 can be opened to replace the activated carbon inside the spherical adsorption chamber 72 before it can be reinstalled for the next operation.

[0048] After the door of oven 1 is closed, oven 1 and the circulating fan 5 are started. The heat inside oven 1 is blown out from the honeycomb panel 9 fixedly connected to the inner wall of oven 1. Then, the dynamic airflow guiding component 8 starts to operate. First, the drive seat 83 connected to the bottom of oven 1 rotates, driving the hollow tube 82 fixedly connected to the top to rotate. At the same time, the rotating fan disc 81 connected to the top of the hollow tube 82 rotates, driving the airflow to be transported into the hollow tube 82. Then, the airflow is transported through the hollow tube 82 to multiple air ducts 84 at different angles installed at the end of the hollow tube 82. Then, the air ducts 84 blow the airflow onto the brake pads on each layer of support frame 10. At the same time, with the drive... The seat 83 drives the hollow tube 82 to rotate, and the connecting block 85, which is fixedly connected to the end of the air duct 84, drives the arc-shaped metal plate 86 to rotate in the same direction as the drive seat 83. As multiple arc-shaped metal plates 86 rotate, the airflow inside the oven 1 forms a vortex, which continuously washes the brake pads inside the oven 1, making the brake pads heat up more evenly. Finally, after the brake pads have finished heat treatment and the oven 1 has cooled down, the support plate 61 is pulled out to the unloading point, and then the pin baffle 611 inserted at the bottom of the hollow frame 62 is pulled out. As the pin baffle 611 is pulled out, the brake pads fall directly out of the hollow frame 62, completing the unloading.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
