Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of brake disc heat treatment, in particular to a heat treatment equipment for automobile brake disc. BACKGROUND

[0002] There are disc brake, drum brake and air brake. More vehicle types adopt disc brake structure. Because disc brake is better in heat dissipation than drum brake, it is not easy to produce heat recession in high speed braking state, so its high speed braking effect is good. But in low speed cold brake, its braking effect is not as good as drum brake.

[0003] Brake disc is a round disc, which is also rotating when the vehicle is running. Brake caliper clamps brake disc to produce braking force, which clamps brake disc to slow down or stop the vehicle when the brake is stepped on. Brake disc braking effect is good, and it is easier to maintain than drum brake.

[0004] Heat treatment process generally includes heating, holding and cooling three processes, sometimes only heating and cooling two processes. These processes are connected with each other and cannot be interrupted. Heating is one of the important processes of heat treatment. There are many heating methods for metal heat treatment. The earliest one is to use charcoal and coal as heat source, and then liquid and gas fuel are applied.

[0005] The application of electricity makes heating easy to control and has no environmental pollution. These heat sources can be used for direct heating or indirect heating through molten salt or gold, and even floating particles. When metal is heated, the workpiece is often exposed to air, and oxidation and decarburization (i.e. the carbon content of the surface of steel parts is reduced) often occur, which has a very adverse effect on the surface performance of the parts after heat treatment. Therefore, metal should be heated in a controllable atmosphere or protective atmosphere, molten salt and vacuum, or protected by coating or packaging.

[0006] Heating temperature is one of the important process parameters of heat treatment process. The selection and control of heating temperature is the main problem to ensure the quality of heat treatment. The heating temperature is different for different metal materials and heat treatment purposes, but generally it is heated to above the phase transition temperature to obtain high temperature structure. In addition, the transformation requires a certain time, so when the surface of the metal workpiece reaches the required heating temperature, it also needs to maintain at this temperature for a certain time to make the internal and external temperature consistent and the microstructure transformation complete. In the field of brake disc, heat treatment is often used to increase the hardness of brake disc.

[0007] The existing reference number CN115679070A Chinese patent discloses an automobile brake disc surface heat treatment tool, which comprises a bottom plate, a connecting plate fixedly connected to the center of the upper surface of the bottom plate, a through hole penetrating through the center of one side of the connecting plate, an installation hole formed in the inner wall of the through hole, a spring fixedly connected to one end of the installation hole, a slide rod fixedly connected to the top end of the spring, an arc-shaped fixing plate fixedly connected to one end of the slide rod, a placement rod slidingly connected to the outer wall of the arc-shaped fixing plate, and a brake disc slidingly connected to the outer wall of the placement rod. First, the placement rod is inserted into the through hole, the spring in the installation hole is contracted, the slide rod is contracted into the installation hole during the contraction of the spring, and the arc-shaped fixing plate is fitted with the outer wall of the placement rod. This design facilitates the placement of placement rods of different thicknesses in the through hole, thereby facilitating the placement of brake discs of different thicknesses on the placement rod.

[0008] The existing reference number CN114807568A Chinese patent discloses an automobile brake disc surface heat treatment tool, which relates to the field of automobile accessory machining technology and comprises a cabinet door, a cabinet body and a heating mechanism. The cabinet door is hingedly connected to the front edge of the cabinet body, and the heating mechanism is fixedly connected to the top of the cabinet body. An inner wall of the cabinet body is fixedly connected with a placement seat, and the inner wall of the placement seat is provided with a movable support plate. The movable support plate is slidably connected to the cabinet body through the cooperation of the sliding groove, the sliding bar, the movable support plate, the arc-shaped groove, the movable column, the first elastic member and the support hanging rod. The movable support plate can be easily slid out, and the automobile brake disc can be easily hung on the semicircular ring. The arc-shaped groove can place the automobile brake disc to avoid stacking. Under the action of the gravity of the automobile brake disc, the semicircular ring can extrude the first elastic member through the movable column, and the movable column can be inserted into the inside of the positioning groove.

[0009] The above-mentioned patents all have the functions of placing and fixing the automobile brake disc, but they do not disclose an integrated structure for feeding, fixing, heating and discharging the automobile brake disc. In the traditional heat treatment process, the heat treated parts need to be transferred to the next process after completing a process, which consumes more manpower and resources and reduces work efficiency and production efficiency. Since the automobile brake disc does not have an integrated structure for feeding, fixing, heating and discharging the automobile brake disc, the heat treated parts need to be split into processes when multiple processes are performed, which increases the number of processes and reduces work efficiency. Therefore, the present inventors propose a heat treatment equipment for automobile brake disc to solve the above-mentioned technical problems of feeding, fixing, heating and discharging the automobile brake disc using an integrated structure.
