Description

Technical Field

[0001] The utility model relates to the technical field of brake pad processing, in particular to a heat treatment device for brake pads. Background Art

[0002] Automotive brake pads, also known as brake shoes, refer to the friction material affixed to the brake drum or disc that rotates against the wheel. The friction lining and pads withstand external pressure, generating friction to decelerate the vehicle. The thermal insulation layer is made of a non-heat-conducting material for thermal insulation. The friction pads, composed of friction material and adhesive, are pressed against the brake disc or drum during braking, generating friction to decelerate and stop the vehicle. Automotive brake pads typically consist of a steel plate, an adhesive thermal insulation layer, and a friction pad. The steel plate undergoes a coating to prevent rust. During the coating process, an SMT-4 furnace temperature tracker monitors the temperature distribution to ensure quality. Currently, due to the significant heat generated by the friction between the brake pad and the wheel during braking, brake pads require high heat resistance and require heat treatment. However, existing equipment for heat treatment, due to the small size of the workpieces and the lack of proper placement, results in disordered stacking of the brake pads, resulting in uneven heating of the workpieces and uneven heat treatment, impacting product quality. The patent number is CN217418767U, and its name is a brake pad heat treatment device. A shelf body is set in a box, and the brake pads are evenly placed on the shelf. However, in this patent, spiral heating wires are set on both side end faces of the box. Although the heating chamber can be heated, the temperature of the side end faces of the box will definitely be higher than the temperature in the middle of the box. This will make the temperature of the brake pad located in the middle of the box lower than the temperature at the end of the box, resulting in uneven temperature of the brake pad, thereby affecting the quality of the workpiece. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a heat treatment device for brake pads.

[0004] According to the technical solution provided in the embodiment of the present application, a heat treatment device for brake pads includes a box body, a brake pad placement rack is arranged in the box body by sliding rails, a heating component placement plate is horizontally arranged on one side end of the box body, a heating component is slidably arranged on the heating component placement plate, and the heating component slides on the heating component placement plate to be inserted into and removed from the box body; after several heating plates arranged in sequence from top to bottom on the heating component are movably inserted into the box body, they are respectively placed under several placement plates on the brake pad placement rack to achieve heating of the brake pads on each placement plate.

[0005] Furthermore, several heating plates on the heating assembly are fixed on one side end face of the vertically placed plate in sequence from top to bottom, and the heating assembly is slidably connected to the heating assembly placement plate through the vertically placed plate, so that the heating plates on the heating assembly can be inserted into and extended from the box.

[0006] Furthermore, a cooling pipe is provided on the lower end surface of the heating plate. The cooling pipes on several heating plates are connected. The cooling pipes are connected to the vacuum pump through a telescopic hose. When the cooling pipes move, they can be fixedly connected to the cooling source, thereby facilitating the reduction of the temperature inside the box.

[0007] Furthermore, a plurality of placement plates on the brake pad placement rack are fixedly connected through vertical columns, which facilitates the placement of the heating plate.

[0008] Furthermore, the box body is provided with double-door doors on both sides to facilitate the placement and removal of brake pads.

[0016] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0017] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0018] A heat treatment device for brake pads, such as Figure 1 and Figure 2 The left and right end faces of the box body 1 are both provided with double-door doors, and a brake pad placement rack 2 is provided in the box body 1 through a slide rail. Figure 3 It can be seen that the brake pad placement rack 2 is provided with a plurality of horizontal placement plates 21 from top to bottom, and the plurality of placement plates 21 are fixed by four vertically placed vertical columns 22;

[0019] like Figure 1 、 Figure 2 and Figure 4 As shown, a horizontally placed heating component placement plate 3 is fixedly provided at the lower end of the front end face of the box body 1, and the heating component 4 is slidably connected to the heating component placement plate 3 through a vertically placed vertical placement plate 42, and a plurality of horizontally placed heating plates 41 are arranged in sequence from top to bottom on the rear end face of the vertical placement plate 42, and the heating plates 41 are all located below the placement plate 21 when inserted into the box body 1, and a cooling pipe 5 is fixedly provided on the lower end face of the heating plate 41, and the cooling pipe 5 is fixedly passed through the vertical placement plate 42, and a plurality of cooling pipes 5 located at the lower end face of the heating plate 41 are connected, such as air entering from the cooling pipe 5 located at the lower end part of the heating component 4 through a vacuum pump, and exiting from the cooling pipe 5 located at the upper end part of the heating component 4, and the heating plates 41 are all connected to the power supply through wires (not shown in the figure).

[0020] The heating plate 41 is a horizontally placed disc-shaped heating tube, or a horizontally placed serpentine-shaped heating tube, or a horizontally placed rectangular-shaped heating tube. A high-temperature resistant heat-conducting material, such as silicon carbide ceramic material or high-temperature alloy material, may be fixedly sleeved on the outer end surface of the heating tube.

[0021] Before use, place multiple brake pads on the placement plate 21 of the brake pad placement rack 2, then push them into the box 1 through the slide rails and close the box door;

[0022] Then, slide the heating assembly 4 onto the heating assembly placement plate 3 until the heating plate 41 on the heating assembly 4 is inserted into the box body 1 and the vertical placement plate 42 abuts against the front surface of the box body 1. At this time, the heating plate 41 is located below the placement plate 21.

[0023] At this time, the heating plate 41 is powered on, and the heating plate 41 will heat up inside the box 1. Since the heating plates 41 are evenly arranged below the placement plate 21, the brake pads on the placement plate 21 can be heated evenly. A temperature sensor can be set in the box 1 to regulate the temperature inside the box 1 together with the heating plate 41 to prevent the performance of the brake pads from being affected by excessively high or low temperatures.

[0024] After the heat treatment of the brake pad is completed, the heating plate 41 is turned off, and then low-temperature air is pumped into the cooling pipe 5 through a vacuum pump. When the low-temperature air flows through the cooling pipe 5, it will drive the heat in the box 1 to flow out, thereby reducing the temperature in the box 1; and when the temperature in the box 1 drops to a specific value, water can also be pumped into the cooling pipe 5 to achieve a rapid drop in temperature without causing thermal expansion and contraction of the cooling pipe 5, thereby damaging the cooling pipe 5.

[0025] When the temperature inside the box 1 cools down to a temperature that can be removed, first move the heating component 4 on the heating component placement plate 3, so that the heating plate 21 and the cooling tube 5 are moved out of the box 1, making it convenient for the brake pad placement rack 2 to be moved out of the box 1 and wait for the next batch of brake pads to be loaded for heat treatment.

[0026] The above description is merely an illustration of the preferred embodiments of the present application and the technical principles employed. The scope of the invention herein is not limited to the technical solutions formed by the specific combination of the aforementioned technical features, but also encompasses other technical solutions formed by any combination of the aforementioned technical features or their equivalents without departing from the inventive concept. For example, a technical solution formed by replacing the aforementioned features with (but not limited to) technical features with similar functions disclosed in this application.
