Description

Technical Field

[0001] This utility model relates to the technical field of heat treatment production line equipment, specifically a heat treatment production line with air cooling function. Background Technology

[0002] Heat treatment refers to a metal hot working process in which metallic materials (such as steel plates) are heated, held at temperature and cooled in a solid state to obtain the desired microstructure and properties. In the production and processing of intelligent heat treatment production lines, when steel plates are only hot rolled, the plasticity of the steel plates increases and the deformation resistance decreases, which greatly reduces the energy consumption of steel plate deformation. Hot rolling can improve the processing performance of steel plates, that is, break up the coarse grains in the casting state, significantly heal cracks, reduce or eliminate casting defects, transform the as-cast structure into a deformed structure, and improve the processing performance of steel plates.

[0003] For example, an intelligent heat treatment production line with announcement number CN218146841U includes: an intelligent control system, an automatic feeding system, a roller hearth quenching furnace, a plate and frame hydraulic press, an automatic station switching device, an automatic detection device, and a material unloading and stacking device; the automatic feeding system is located at the front end of the intelligent heat treatment production line; the roller hearth quenching furnace is located at the rear of the automatic feeding system; the plate and frame hydraulic press is located at the rear of the roller hearth quenching furnace; the automatic station switching device is located at the rear of the plate and frame hydraulic press; the automatic detection device is located at the rear of the automatic station switching device; and the material unloading and stacking device is located at the rear of the automatic detection device.

[0004] The heat treatment design of the above-mentioned device can heat the steel plates and other metals conveyed at the upper end of the conveyor belt to achieve heat treatment operation. However, since the heating furnace is installed at the upper end of the machine body, and the steel plates and other materials have a large surface coverage, the heat transfer efficiency in one direction is low, which makes the heat treatment process longer and increases the consumption of resources. Utility Model Content

[0005] The purpose of this invention is to provide a heat treatment production line with air cooling function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat treatment production line with air cooling function, including a support plate, a support column installed at the lower end of the support plate, and a working body assembled at the upper end of the support plate. A transmission layer is provided inside the working body, a conveying plate is installed inside the transmission layer, and an empty opening is provided in the middle of the conveying plate. A heating fire tube is installed at the lower end of the empty opening, a tempering furnace is installed at the lower end of the heating fire tube, and connecting pipes are assembled on the surface of the tempering furnace. An air cooling mechanism is assembled at the outlet of the working body.

[0007] Preferably, rotating columns are installed on both sides of the conveying plate, and the surface of the rotating columns is fitted with external protrusions, with an insertion hole provided on one side of the transmission layer.

[0008] Preferably, the rotating column is mounted on the through hole, and the adjacent rotating columns are fitted with connecting strips, and the drive shaft is installed in the middle of the transmission layer.

[0009] Preferably, the drive motor is connected to the outside of the drive shaft, and a fixing plate is mounted on the side of the drive motor, with fixing bolts mounted on the fixing plate.

[0010] Preferably, the inner surface of the transmission layer is provided with an indentation layer, and a heating unit is assembled inside the indentation layer, and several heating nozzles are assembled on the surface of the heating unit.

[0011] Preferably, a compressor is installed at the end of the working body, and a cooling mechanism is connected to the lower end of the compressor, with an output port assembled at the lower end of the cooling mechanism.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. Compared with other heat treatment production lines, this device is mainly for the heat treatment of a series of metal materials such as steel plates. Since steel plates and other materials are generally large and wide after manufacturing, heating furnaces are installed at the top and bottom of the device to heat the inside. The adjacent conveyor coils are designed with high temperature resistant materials and a large gap is left between them to facilitate heat transfer. The heating furnaces at the top and bottom can heat the steel plate from the top and bottom at the same time, which improves the efficiency of heat treatment.

[0013] 2. In addition, the device is equipped with an air-cooling unit at the end to quickly cool down the heat-treated steel plates and other metals, thereby accelerating the output efficiency of the steel plates and enhancing the continuity of the heat treatment process. The device itself is simple and effective in design, making subsequent disassembly or maintenance faster and easier to operate. Attached Figure Description

A support column 1 is installed at the lower end of the bearing plate 2. A connecting rod is provided between the support columns 1 to increase the stability of the support columns 1. The upper end of the bearing plate 2 is equipped with a working body 7. A transmission layer is provided inside the working body 7. A conveying plate is installed inside the transmission layer. The conveying plate 3 is designed in a U-shape and has an empty opening in the middle. A heating fire tube 14 is installed at the lower end of the empty opening. A tempering furnace 6 is installed at the lower end of the heating fire tube 14. A connecting pipe 15 is installed on the surface of the tempering furnace 6. The connecting pipe 15 is connected to the tempering furnace 6 at the upper end. Both work simultaneously. An air-cooling mechanism is installed at the outlet of the working body 7. refer to Figure 2 The main body is a conveying plate 3. Rotating columns 10 are installed on both sides of the conveying plate 3. The rotating columns 10 are inserted into the inner side of the conveying plate 3, and the surface of the rotating columns 10 is equipped with external protrusions 9. The installation of external protrusions 9 allows for internal space to facilitate the transfer of high temperature when transporting steel plates or other metal plates. There is an insertion hole on one side of the transmission layer. A rotating shaft is installed at the front end of the other side of the rotating column 10. The size of the rotating shaft is slightly smaller than that of the rotating column 10 and is used for the transfer of kinetic energy. It is installed on the insertion hole, and a connecting belt 11 is installed between adjacent rotating shafts. A drive shaft 13 is installed in the middle of the transmission layer. The drive shaft 13 is connected to the outside of the drive motor 8, and a fixing plate is installed next to the drive motor 8. A fixing bolt is installed on the fixing plate. The fixing plate and the fixing bolt effectively fix the drive motor 8, while the drive shaft 13 serves as the kinetic energy source for the rotating columns 10 inside the device. refer to Figure 3 The main body is a transmission layer. The inner surface of the transmission layer is provided with an indentation layer, and a heating unit 17 is installed inside the indentation layer. Several heating nozzles 18 are installed on the surface of the heating unit 17. A compressor 5 is installed at the end of the working body 7, and the lower end of the compressor 5 is connected to a wind-cooling mechanism. An output port 16 is installed at the lower end of the wind-cooling mechanism. A wind-cooling baffle 4 is installed on the outside of the output port 16 to guide the wind-cooling effect generated by the output port 16 and ensure that the generated cold air is output to the surface of the metal plate.

[0018] In actual use, the metal plate and other devices are first transported to the upper end of the rotating column 10 inside the conveying plate 3. The design of the outer protrusion 9 creates an air gap inside to facilitate the transfer of high temperature. As the drive motor 8 is turned on, the internal rotating column 10 starts to rotate, carrying the metal plate to the middle position. The tempering furnace 6 at the upper and lower ends is turned on, and the metal plate is heat-treated by the heating fire tube 14 and heating nozzle 18. The high temperature treatment on both sides can accelerate the heat treatment efficiency of the metal plate and avoid the possibility of imperfection in the heat treatment process. After completion, the rotating column 10 rotates to transport the metal plate to the outside. The air-cooling mechanism at the end transfers cold air to the surface of the metal plate through the output port 16 to achieve rapid cooling, which facilitates subsequent removal and also improves the continuity of the workflow.
