[0041] As Figure 3 , Figure 8 and Figure 10As shown, the water cooling assembly 7 includes a support seat 71 fixedly installed at the top end of the box body 1, the top end of the support seat 71 is fixedly installed with an electric push rod two 72, the extending end of the electric push rod two 72 is connected with a mounting rack 73, the inner side of the mounting rack 73 is fixedly installed with a cooling pipe rack 74, the cooling pipe rack 74 is made of high thermal conductivity metal material, the cooling pipe rack 74 is set as a serpentine channel, one end of the cooling pipe rack 74 is connected with a storage barrel 75 through a hose, the storage barrel 75 is installed at the top end of the box body 1, one side of the storage barrel 75 is connected with a water pump 76 through a hose, the water pump 76 is fixedly installed at the top end of the box body 1, the other end of the water pump 76 is connected with a water tank 77 through a pipeline, the water tank 77 is fixedly installed at the top end of the box body 1, one side of the water tank 77 is communicated with one end of the cooling pipe rack 74 through a hose, the top end of the storage barrel 75 is fixedly connected with a heat exchanger 78, by setting the water cooling assembly 7, the operator can control the electric push rod two 72 to push the mounting rack 73 through the control module 2, so that the mounting rack 73 is lowered to the position height of opening the cabinet door 3, at this time, the cooling pipe rack 74 is the same height as the bracket 67, the cooling liquid in the water tank 77 is pumped into the inside of the storage barrel 75 through the pipeline by the water pump 76, and enters the inside of the cooling pipe rack 74 through the hose by the pushing force between the cooling liquids, and the cooling liquid flows back into the inside of the water tank 77 again through the pipeline along the path of the cooling pipe rack 74, the cooling pipe rack 74 is made of high thermal conductivity metal material, and the inside is designed as a serpentine flow channel, so as to increase the contact area of the cooling liquid and the pipe wall, and improve the heat exchange efficiency, the cooling pipe rack 74 is arranged close to the bracket 67, and the surface thereof maintains uniform and moderate spacing with the heat sensitive area of the brake pad, so as to ensure the symmetry of the cooling air flow or the heat conduction path, avoid the brake pad from generating thermal stress cracks or warping deformation due to local rapid cooling, and the heat exchanger 78 at the top end of the storage barrel 75 is used for heat exchange between the cooling liquid in the inside of the storage barrel 75 and the air outside, so as to reduce the temperature of the cooling liquid itself.

[0042] As Figure 9 and Figure 10As shown, the air cooling assembly 8 comprises a mounting frame 81 fixedly installed on the inner side of the mounting rack 73, two heat dissipation fans one 82 are symmetrically fixedly installed on the top inner side of the mounting frame 81, and two heat dissipation fans two 83 are rotatably installed on the two sides of the mounting frame 81 respectively, one side of each heat dissipation fan two 83 is connected with a driving motor 84, the driving motor 84 is fixedly installed on one side of the mounting frame 81, and a temperature detector 85 is fixedly installed on one side of the mounting frame 81, by arranging the air cooling assembly 8, the hot air is extracted upwards through the two heat dissipation fans one 82 on the top inner side of the mounting frame 81 while the brake pad is water-cooled and heat-dissipated, at the same time, the driving motor 84 is controlled by the control module 2 to drive the heat dissipation fan two 83 to rotate 180° on the inner side of the mounting frame 81, so as to realize the automatic switching of the heat dissipation fan two 83 between the "air suction" and "air blowing" modes, when one side of the heat dissipation fan two 83 is in the air suction state, the high-temperature air in the cooling area is quickly extracted, and the other side of the heat dissipation fan two 83 blows the low-temperature air treated by cooling at the same time, forming a directional convection air duct, which can significantly enhance the air circulation efficiency of the cooling area, the "air suction and air extraction" cooperative cooling strategy effectively breaks the cooling boundary layer, improves the convective heat transfer coefficient, and makes the heat of the cooling pipe rack 74 surface and the brake pad body quickly removed, in the process, the airflow flowing at high speed passes through the blade surface of the impeller 69, generating a continuous aerodynamic thrust to push the impeller 69 to rotate at low speed below the bracket 67, the impeller 69 is connected with the bracket 67 through a transmission shaft, drives the whole bracket 67 to rotate slowly and stably in the heat treatment rack 64, and the rotation of the bracket 67 makes the brake pad clamped by the clamp 68 on the outer side of the bracket 67 uniformly exposed to the cooling airflow in space, avoiding the problems of large temperature difference between upper and lower surfaces, uneven cooling and the like caused by traditional static cooling, so as to ensure that the brake pad shrinks uniformly, reduce thermal stress residue, and improve product size stability and structural reliability.

[0043] The working principle of the technical solution provided by the application is as follows:

[0044] The operator records the temperature of the four areas inside the box 1 and the placement time of the brake pad through the control module 2 in cooperation with the sensor, and adjusts the temperature through the heating element 4 in the four areas inside the box 1. First, the operator clamps the drum brake pad through the clamp 68 and places it on the bracket 67, drives the corresponding electric push rod one 61 through the control module 2, retracts the extension end of the electric push rod one 61, makes the extension end of the electric push rod one 61 pull the connected connecting rod one 62, because the connecting rod one 62 is rotationally connected with the connecting rod two 63, so that the connecting rod two 63 pulls the corresponding heat treatment frame 64 to move to the inside of the box 1, the two guide rods 65 at the top of the heat treatment frame 64 move along the inside U-shaped groove of the guide plate 66, when the guide rod 65 passes through the corner of the U-shaped groove inside the guide plate 66, it drives the heat treatment frame 64 to turn 90°, the bracket 67 of the heat treatment frame 64 can be aligned with the corresponding heating element 4 on one side to ensure that the workpiece and the heat source maintain the best heat conduction distance, the corresponding heating element 4 on one side starts to blow hot air to heat the brake pad workpiece clamped by the clamp 68 on the bracket 67 according to the preset program of the control module 2, at the same time, part of the hot air flow blown by the heating element 4 flows and impacts the surface of the impeller 69 blade located below the bracket 67, uses the kinetic energy of the airflow to drive the impeller 69 to rotate slowly, the impeller 69 drives the upper bracket 67 to rotate inside the heat treatment frame 64, which can further disturb the airflow field in the heating cavity, break the static distribution of the local hot and cold areas inside the box 1, make the hot air form a spiral convection on the upper and lower surfaces and edge areas of the bracket 67 and the brake pad, and improve the heating uniformity inside the box 1.

[0045] When the operator observes an area where heat treatment has ended through control module 2, the operator can manually open the cabinet door 3 of the corresponding area and activate the electric push rod 61 on the corresponding side of the heat treatment rack 64 to be pulled out. The electric push rod 61 pushes outward of the housing 1, pushing connecting rod 62 and connecting rod 63. Under the transmission of connecting rod 62 and connecting rod 63, the heat treatment rack 64 moves outward of the housing 1 and is guided by two guide rods 65 sliding within the U-shaped groove of the guide plate 66. The heat treatment rack 64 follows the guide rods 65 along the vertical long groove on one side of the U-shaped groove of the guide plate 66, and then moves in the direction of the horizontal groove perpendicular to the vertical long groove, so that the guide rods 65 walk out of the L-shaped part of the U-shaped groove. During the process, the heat treatment rack 64 is first pulled out horizontally from inside the housing 1 and rotates 90° following the trajectory of the guide plate 66. During the movement, connecting rod 62 and connecting rod 63 rotate in coordination, which facilitates the operation of the operator or automated machinery. The heat-treated brake pad workpiece is safely and efficiently removed from the bracket 67 by hand, and a new workpiece to be treated is loaded into the clamp 68. At the same time, the heat insulation plate 640 on one side of the heat treatment rack 64 can block the opening area of ​​the chamber 1, forming a tight thermal barrier for the opening area of ​​the chamber 1. The heat insulation plate 640 is made of high-temperature resistant ceramic fiber material, which has excellent heat insulation performance and can effectively prevent residual heat inside the chamber 1 from escaping to the outside. It also insulates the brake pads inside another set of heat treatment racks 64, which not only improves the energy utilization efficiency of the oven equipment, but also significantly improves the safety of the working environment and prevents operators from accidentally coming into contact with high-temperature surfaces and getting burned. After loading and unloading is completed, the control module 2 controls the corresponding electric push rod 61 to reverse the action, driving the connecting rod 62 and the connecting rod 63 to move in the opposite direction, driving the heat treatment rack 64 back along the original path and re-entering the chamber 1, and aligning one side of the bracket 67 with the heating element 4, ready for the next cycle of heat treatment operation.

[0046] Before taking the brake pad after heat treatment, the operator can control the electric push rod two 72 through the control module 2 to push the mounting frame 73, so that the mounting frame 73 is lowered to the position height of opening the cabinet door 3, at this time, the cooling pipe rack 74 is the same height as the bracket 67, the cooling liquid in the water tank 77 is pumped into the inside of the storage barrel 75 through the pipeline by the water pump 76, and enters the inside of the cooling pipe rack 74 through the hose by the pushing force between the cooling liquids, and the cooling liquid flows back into the inside of the water tank 77 through the pipeline along the path of the cooling pipe rack 74, the cooling pipe rack 74 is made of high thermal conductivity metal material, and the inside is designed as a serpentine flow channel, so that the contact area of the cooling liquid and the pipe wall is increased, the heat exchange efficiency is improved, the cooling pipe rack 74 is arranged close to the bracket 67, and the surface thereof keeps uniform and moderate spacing with the heat sensitive area of the brake pad, so that the symmetry of the cooling air flow or the heat conduction path is ensured, the local cooling is avoided to be too fast to cause the brake pad to produce thermal stress cracks or warping deformation, and the heat exchanger 78 at the top end of the storage barrel 75 is used for heat exchange between the cooling liquid in the inside of the storage barrel 75 and the air outside, so that the temperature of the cooling liquid itself is reduced;

[0047] While the brake pad is water-cooled and heat-dissipated, the hot air is extracted upwards by the two heat dissipation fans one 82 on the top inside of the mounting frame 81, at the same time, the control module 2 controls one side to drive the motor 84, so that the drive motor 84 drives the heat dissipation fan two 83 to rotate 180° on the inside of the mounting frame 81, so that the heat dissipation fan two 83 is automatically switched between the "air suction" and "air blowing" two modes, when one side heat dissipation fan two 83 is in the air suction state, the high-temperature air in the cooling area is quickly extracted; the other side heat dissipation fan two 83 blows the low-temperature air cooled simultaneously, forming a directional convection air duct, which can significantly enhance the air circulation efficiency of the cooling area. The "one suction and one extraction" cooperative heat dissipation strategy effectively breaks the cooling boundary layer, improves the convective heat transfer coefficient, and makes the heat of the cooling pipe rack 74 surface and the brake pad body quickly removed. In this process, the airflow flowing at high speed passes through the blade surface of the impeller 69, generating a continuous aerodynamic thrust to push the impeller 69 to rotate slowly under the bracket 67. The impeller 69 is connected with the bracket 67 through a transmission shaft, driving the whole bracket 67 to rotate slowly and stably inside the heat treatment frame 64. The rotation of the bracket 67 makes the brake pad clamped by the clamp 68 on the outside of the bracket 67 uniformly exposed to the cooling airflow in space, avoiding the problems of large temperature difference between upper and lower surfaces, uneven cooling and the like caused by traditional static cooling, so as to ensure that the brake pad shrinks uniformly, reduces thermal stress residue, improves product size stability and structural reliability. The temperature detector 85 continuously monitors the heat dissipation of the brake pad on the bracket 67. The operator can judge the temperature of the brake pad through the data uploaded by the temperature detector 85 to the control module 2. When the temperature decreases to room temperature, the control electric push rod two 72 drives the mounting frame 73 and the mounting frame 81 to reset, and then the operator can quickly take the brake pad workpiece.
