Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology for metal parts, and specifically to a heat treatment device for surface treatment of metal parts. Background Technology

[0002] Surface treatment of metal components is one of the key processes for improving their performance and extending their service life. In industrial production, metal components often experience performance degradation due to friction, wear, corrosion, or high-temperature environments. While traditional surface treatment methods (such as coatings and electroplating) can provide some protection, they often struggle to simultaneously meet multiple performance requirements, including hardness, wear resistance, corrosion resistance, and fatigue strength. Heat treatment technology, by controlling the heating, holding, and cooling processes of metal materials, can significantly improve their surface and internal microstructure, thereby enhancing their overall performance.

[0003] Existing heat treatment equipment cannot automate or continuously transport and process metal parts during heat treatment, and relies heavily on manual operation or external auxiliary equipment to transfer parts between heat treatment zones.

[0004] For example, in the mechanical metal parts surface heat treatment processing device disclosed in patent CN217230859U, the movement of the metal parts mainly relies on the moving mechanism. The moving mechanism drives the bevel gear to rotate by manually rotating the rotating rod (handwheel), which in turn drives the lead screw to rotate, pushing the sliding block to move in the slide groove, thereby driving the top rod and clamping block to move to realize the entry and exit of the metal parts in the heating zone. This process relies entirely on manual operation of the handwheel to control the movement of the metal parts. Due to the reliance on manual operation, not only is the operation time increased, but the operation speed is also limited by human intervention. It is impossible to quickly and efficiently complete the transfer of metal parts between heat treatment zones, making it difficult to achieve seamless heat treatment and continuous production of metal parts.

[0005] Therefore, it is necessary to invent a heat treatment device for surface treatment of metal parts to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a heat treatment device for surface treatment of metal parts, which solves the problem that metal parts cannot be automatically and continuously transported and processed.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a heat treatment device for surface treatment of metal parts, comprising a frame and a mesh belt conveyor belt. Mounting frames are symmetrically arranged on the front and rear sides above the frame. Five conveyor rollers are rotatably mounted on the mounting frames, and the mesh belt conveyor belt is tensioned and fitted onto the five conveyor rollers. An upper hot air hood is provided on the top surface of the mounting frames, directly above the mesh belt conveyor belt. A lower hot air hood is correspondingly provided below the mesh belt conveyor belt. A hot air blower is provided on one side of the bottom of the frame, and a material collection box is provided on the other side of the bottom of the frame.

[0008] Preferably, one end of a conveyor roller located on the upper side of the mounting frame is connected to the output shaft of a drive motor via a coupling. The drive motor, as a power source, is directly connected to the conveyor roller via the coupling, which can efficiently transmit the rotational power of the motor to the conveyor roller.

[0009] Preferably, power is transmitted between every two adjacent conveyor rollers via a synchronous belt drive assembly. The purpose of this design is to ensure the synchronous operation of multiple conveyor rollers, thereby ensuring that the mesh belt conveyor can smoothly and accurately transport metal parts and realize an automated and continuous production process.

[0010] Preferably, the outlet end of the hot air blower is connected to an air supply pipe, and the outlet end of the air supply pipe extends through the interior of the upper hot air hood and the lower hot air hood respectively. The hot air blower, as a hot air generating device, delivers hot air to the upper hot air hood and the lower hot air hood through the air supply pipe, providing the required heat source for the heat treatment of metal parts.

[0011] Preferably, the upper and lower hot air hoods are provided with multiple intersecting hot air pipes, and each hot air pipe has several air outlets. The arrangement of multiple intersecting hot air pipes can expand the coverage of hot air and ensure that hot air can be blown evenly onto the metal parts on the mesh conveyor belt.

[0012] Preferably, the collection box is located below the discharge end of the mesh belt conveyor, a design intended to facilitate and efficiently collect heat-treated metal parts.

[0013] Preferably, a control cabinet is provided on one side of the frame, and a PLC controller is provided in the control cabinet to control the operation of the drive motor and the hot air blower.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model uses five conveyor rollers to operate synchronously, thereby driving the mesh belt conveyor to run smoothly and accurately. Metal parts placed on the mesh belt conveyor can enter the heat treatment area sequentially as the mesh belt conveyor runs, without the need for frequent manual operation. This solves the problem of the inability to achieve automated and continuous conveying and processing of metal parts, greatly improves production efficiency, and reduces labor costs and labor intensity.

[0016] 2. This utility model features an upper hot air hood directly above the mesh conveyor belt and a corresponding lower hot air hood below it. Because the mesh conveyor belt has a certain degree of air permeability, hot air can pass through the mesh openings, ensuring that the hot air is evenly blown onto the metal parts on the mesh conveyor belt. This achieves heat treatment on both sides of the metal parts, making the metal parts heat-treated more evenly, improving the quality and effect of the heat treatment, meeting the surface treatment needs of different metal parts, and enhancing the product's market competitiveness.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5The heat treatment equipment for surface treatment of metal parts shown includes a frame 1 and a mesh belt conveyor belt 5. Mounting frames 2 are symmetrically arranged on the front and rear sides above the frame 1. Five conveyor rollers 3 are rotatably mounted on the mounting frames 2. One end of one of the conveyor rollers 3 located on the side above the mounting frame 2 is connected to the output shaft of the drive motor 4 through a coupling. Power is transmitted between every two adjacent conveyor rollers 3 through a synchronous belt drive assembly. The mesh belt conveyor belt 5 is tensioned and sleeved on the five conveyor rollers 3.

[0026] In this embodiment, the drive motor 4 serves as a power source and is directly connected to a conveyor roller 3 via a coupling. This allows the motor's rotational power to be transmitted to the conveyor roller 3 efficiently and stably. Furthermore, the five conveyor rollers 3 together support the mesh belt conveyor 5, ensuring that the mesh belt conveyor 5 remains stable during operation. The mesh belt conveyor 5 can run continuously, smoothly transporting metal parts from one process to the next without the need for frequent manual handling. This achieves full automation of the metal parts process from feeding and heat treatment to discharging, reducing labor costs and labor intensity.

[0027] The top surface of the mounting frame 2 is provided with an upper hot air hood 6, which is located directly above the mesh belt conveyor belt 5. The lower hot air hood 7 is provided below the mesh belt conveyor belt 5. A hot air fan 8 is provided on one side of the bottom of the frame 1. The air outlet of the hot air fan 8 is connected to an air supply pipe 9, and the air outlet of the air supply pipe 9 extends through the interior of the upper hot air hood 6 and the lower hot air hood 7. Multiple intersecting hot air pipes 10 are provided inside the upper hot air hood 6 and the lower hot air hood 7. Several air outlets 11 are opened on the hot air pipes 10. A material collection box 12 is provided on the other side of the bottom of the frame 1. The material collection box 12 is located below the discharge end of the mesh belt conveyor belt 5.

[0028] In this embodiment, the mesh conveyor belt 5 has a certain degree of air permeability, and hot air can pass through the mesh holes of the mesh belt to heat treat both the upper and lower surfaces of the metal parts at the same time. Compared with the single-sided heating method, this two-sided heat treatment can make the metal parts heat more evenly.

[0029] A control cabinet is installed on one side of the frame 1. The control cabinet contains a PLC controller, which is used to control the operation of the drive motor 4 and the hot air blower 8.

[0030] Working principle of this utility model:

[0031] Refer to the instruction manual appendix Figure 1-5When using this invention, firstly, start the equipment. The drive motor 4 starts running, transmitting power to a connected conveyor roller 3. Since power is transmitted between every two adjacent conveyor rollers 3 via a synchronous belt drive assembly, all five conveyor rollers 3 will rotate synchronously. The five conveyor rollers 3 together support and drive the tensioned mesh conveyor belt 5 to run continuously. At the same time, the hot air blower 8 starts working, drawing in and heating outside air. The heated hot air is then delivered through the air supply pipe 9 to the upper hot air hood 6 and the lower hot air hood 7. Inside the upper and lower hot air hoods 6 and 7, multiple cross-arranged hot air pipes 10 further disperse the hot air. The hot air then flows out from the hot air pipes 10. The hot air is evenly blown out from several air nozzles 11. The metal part to be surface treated is placed at the starting end of the mesh belt 5. As the mesh belt 5 runs, the metal part is smoothly transported to the heat treatment area. Because the mesh belt 5 has a certain degree of air permeability, hot air can pass through the mesh holes of the mesh belt and heat the upper and lower surfaces of the metal part at the same time, making the metal part heat-treated more evenly and ensuring the quality of heat treatment. When the metal part has completed heat treatment, as the mesh belt 5 continues to run to the unloading end, the metal part falls off the mesh belt 5 and into the collection box 12 located directly below the unloading end of the mesh belt 5, completing the entire heat treatment process.
