[0001] This utility model belongs to the field of heat treatment technology, specifically a heat treatment processing device for connectors. Background Technology
[0002] Heat treatment technology is a key process that alters the internal structure and properties of materials by controlling the heating, holding, and cooling processes in the solid state. It is widely used in the processing and manufacturing of materials such as metals, alloys, ceramics, and plastics, aiming to optimize the mechanical, physical, and chemical properties of materials, such as increasing hardness, strength, wear resistance, corrosion resistance, and improving processing performance, thereby meeting specific engineering requirements and extending the service life of workpieces.
[0003] In the prior art, the heating of the connector is often limited to one side, while the other side cannot obtain the same temperature, which has an adverse effect on the heat treatment effect of the connector.
[0004] Therefore, this utility model provides a heat treatment processing device for connectors. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A heat treatment processing device for connectors according to this utility model includes a worktable; a motor is fixedly connected to the outside of the worktable; multiple gears are rotatably connected to both sides of the worktable, the gears meshing with each other; one gear is fixedly connected to the motor; a sliding groove is provided on the top of the gear, the sliding groove is opened on the surface of the worktable; a rack is slidably connected in the sliding groove, the rack meshing with the gear; a support device is provided on the top of the rack; a heating base plate is provided on one side of the sliding groove, the heating base plate is fixedly connected to the worktable; a heat preservation box is provided on the top of the sliding groove, the heat preservation box is fixedly connected to the worktable; a heating top plate is fixedly connected to the bottom of the heat preservation box. During operation, the connector is first installed on the support device, then the heating base plate and heating top plate are activated to heat the contents of the heat preservation box. The heating process begins, followed by motor activation. The motor drives one of the gears to rotate. The gears at the ends of both sides of the worktable are fixedly connected, so when the motor drives one gear, it simultaneously drives the other. The meshing gears rotate, causing the rack at the top of the gear to move. The rack slides within a groove, pulling the connector into the heat treatment chamber for heat treatment. The heating base and top plates simultaneously heat the connector, ensuring both sides receive equal heating. After completion, the motor drives the rack to slide along the groove, allowing it to exit the heat treatment chamber. By using a motor, gears, and rack to move the connector on the worktable, it is supported. The heating base and top plates then simultaneously heat both sides of the connector, resulting in more uniform heating and accelerating the heat treatment process.
[0007] Preferably, the support device includes a fixed frame fixedly connected to the top of the rack, a telescopic rod fixedly connected to one side of the fixed frame, a first clamping block fixedly connected to one end of the telescopic rod, a second clamping block slidably connected to the top of the first clamping block, a spring fixedly connected to the bottom of the second clamping block, and the other end of the spring fixedly connected to the first clamping block. During operation, when the connector is installed between the fixed frames, the second clamping block is first pulled to lift it, causing the spring to stretch. Then, the connector is placed on the first clamping block, and the second clamping block is released, causing the spring to return. The second and first clamping blocks clamp the connector, and the telescopic rod adaptively adjusts the width of the connector. By setting the telescopic rod, the first clamping block, and the second clamping block, the connector is suspended and supported. The telescopic rod can adjust the position of the first and second clamping blocks. When fixing different connectors, ensure that the connector is placed in the center of the workbench for better heating.
[0008] Preferably, multiple curtains are fixedly connected to both ends of the heat preservation box, and multiple insulating cottons are fixedly connected to the outside of the heat preservation box. During operation, the curtains cover both sides of the heat preservation box to reduce the flow of hot air inside the heat preservation box to the outside during the heat treatment process, which would cause rapid temperature loss and reduce the phenomenon of poor heat treatment effect on the connecting parts. During the heat treatment, there is a heat preservation process. After the heating bottom plate and heating top plate are closed, the insulating cotton wraps the outside of the heat preservation box to reduce the rate of heat loss.
[0009] Preferably, a guide rod is fixedly connected to one end of the fixing frame, and a protrusion is fixedly connected to one end of the guide rod. During operation, when the rack enters or exits the insulation box on the workbench, the curtain will obstruct the movement of the rack. During the movement of the rack, the protrusion will preferentially contact the curtain and pry open the gap. As the rack advances, the pried curtain will widen outward along the shape of the guide rod, leaving a gap to facilitate the entry and exit of the connector.
[0010] Preferably, a cooling plate is provided on one side of the insulation box. The cooling plate is fixedly connected to the workbench. An external air pipe is connected to the top of the cooling plate, and multiple air holes are connected to the bottom of the cooling plate. During operation, after the connector is heated and kept warm in the insulation box, it enters the cooling plate. The external air pipe is connected to cold air, which is emitted from the external air pipe and acts on the connector to cool it.
[0011] Preferably, the rack is fixed with shims at both ends. The shims are circular in shape. During operation, the rack slides in the groove, and the ends inevitably collide. The shims protect and buffer the rack, reducing the impact of the rack on the groove and preventing damage to the rack or the groove.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. The heat treatment processing device for connectors described in this utility model uses a motor, gears, and racks to move the connectors on a worktable, lift the connectors, and then use a heating base plate and a heating top plate to heat both sides of the connectors simultaneously, making the connectors more evenly heated and accelerating the heat treatment process.
[0014] 2. The heat treatment processing device for connectors described in this utility model provides suspended support for the connectors by setting a telescopic rod, a first clamping block, and a second clamping block. The telescopic rod can adjust the position of the first clamping block and the second clamping block.

Detailed Implementation
[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figures 1 to 3As shown in the embodiment of this utility model, a heat treatment processing device for connectors includes a worktable 1. A motor 11 is fixedly connected to the outside of the worktable 1. Multiple gears 12 are rotatably connected to both sides of the worktable 1. The gears 12 mesh with each other. One of the gears 12 is fixedly connected to the motor 11. A sliding groove 13 is provided on the top of the gear 12. The sliding groove 13 is formed on the surface of the worktable 1. A rack 14 is slidably connected in the sliding groove 13 and meshes with the gear 12. A support device is provided on the top of the rack 14. A heating base plate 15 is provided on one side of the sliding groove 13. The heating base plate 15 is fixedly connected to the worktable 1. A heat preservation box 16 is provided on the top of the sliding groove 13 and is fixedly connected to the worktable 1. A heating top plate 17 is fixedly connected to the bottom of the heat preservation box 16. During operation, the connector is first installed on the support device. Then, the heating base plate 15 and the heating top plate 17 are started to heat the inside of the heat preservation box 16. The motor 11 drives one of the gears 12 to rotate. The gears 12 at both ends of the worktable 1 are fixedly connected. When the motor 11 drives the gear 12 on one side to rotate, it will simultaneously drive the gear 12 on the other side to rotate. The gears 12 mesh with each other and rotate, driving the rack 14 on the top of the gear 12 to move. The rack 14 slides in the slide groove 13, and the rack 14 drives the connector into the heat treatment box 16 for heat treatment. The heating bottom plate 15 and the heating top plate 17 heat the connector at the same time, so that both sides of the connector can receive the same degree of heating effect. After completion, the motor 11 drives the rack 14 to slide along the slide groove 13 and exit from the heat treatment box 16. By setting up the motor 11, gears 12 and rack 14 to drive the connector to move on the worktable 1, the connector is supported, and the heating bottom plate 15 and heating top plate 17 heat both sides of the connector at the same time, so that the connector is heated more evenly and the heat treatment process is accelerated.
[0024] like Figures 3 to 4As shown, the support device includes a fixed frame 2 fixedly connected to the top of the rack 14. A telescopic rod 21 is fixedly connected to one side of the fixed frame 2. A first clamping block 22 is fixedly connected to one end of the telescopic rod 21. A second clamping block 23 is slidably connected to the top of the first clamping block 22. A spring 24 is fixedly connected to the bottom of the second clamping block 23. The other end of the spring 24 is fixedly connected to the first clamping block 22. During operation, the connecting parts are installed between the fixed frames 2. First, the second clamping block 23 is pulled, lifting the second clamping block 23 and causing the spring 24 to stretch. The connector is then placed on the first clamping block 22, and the second clamping block 23 is released. The spring 24 returns, and the second clamping block 23 and the first clamping block 22 clamp the connector. The telescopic rod 21 adjusts the width of the connector accordingly. By setting the telescopic rod 21, the first clamping block 22 and the second clamping block 23, the connector is suspended and supported. The telescopic rod 21 can adjust the position of the first clamping block 22 and the second clamping block 23. When fixing different connectors, ensure that the connector is placed in the center of the workbench 1 so that the connector can be heated better.
[0025] like Figures 1 to 2 As shown, multiple curtains 3 are fixedly connected to both ends of the heat preservation box 16, and multiple insulating cotton 31 are fixedly connected to the outside of the heat preservation box 16. During operation, the curtains 3 cover both sides of the heat preservation box 16 to reduce the flow of hot air inside the heat preservation box 16 to the outside during the heat treatment process, which would cause the temperature to dissipate rapidly and reduce the phenomenon of poor heat treatment effect on the connecting parts. During the heat treatment, there is a heat preservation process. After the heating bottom plate 15 and the heating top plate 17 are closed, the insulating cotton 31 wraps the outside of the heat preservation box 16 to reduce the rate of heat loss.
[0026] like Figures 2 to 4 As shown, a guide rod 4 is fixedly connected to one end of the fixed frame 2, and a protrusion 41 is fixedly connected to one end of the guide rod 4. During operation, when the rack 14 enters and exits the insulation box 16 on the workbench 1, the curtain 3 will obstruct the movement of the rack 14. During the movement of the rack 14, the protrusion 41 will preferentially contact the curtain 3 and pry open the gap. As the rack 14 advances, the pried curtain 3 will widen outward along the shape of the guide rod 4, leaving a gap to facilitate the entry and exit of the connector.
[0027] like Figures 1 to 5 As shown, a cooling plate 5 is provided on one side of the heat preservation box 16. The cooling plate 5 is fixedly connected to the workbench 1. An external air pipe 51 is connected to the top of the cooling plate 5, and multiple air holes 52 are connected to the bottom of the cooling plate 5. During operation, after the connector is heated and kept warm in the heat preservation box 16, it enters the cooling plate 5. The external air pipe 51 is connected to cold air, and the cold air is emitted from the external air pipe 51 and acts on the connector to cool it.
[0028] like Figure 3As shown, the rack 14 is fixed with pads 6 at both ends. The pads 6 are circular in shape. When working, the rack 14 slides in the groove 13. The ends inevitably collide. The pads 6 protect and buffer the rack 14, reducing the impact of the rack 14 on the groove 13 and preventing damage to the rack 14 or the groove 13.
[0029] Working principle: First, the connector is installed on the support device. Then, the heating base plate 15 and heating top plate 17 are activated to heat the inside of the insulation box 16. Next, the motor 11 is started, driving one of the gears 12 to rotate. The gears 12 at both ends of the worktable 1 are fixedly connected. Thus, when the motor 11 drives one gear 12, it simultaneously drives the other gear 12 to rotate. The gears 12 mesh and rotate, causing the rack 14 at the top of the gear 12 to move. This causes the rack 14 to slide within the slide groove 13, and the rack 14 pulls the connector into the insulation box 16 for heat treatment. The heating base plate 15 and heating top plate 17 simultaneously heat the connector, ensuring that both sides of the connector receive equal heat treatment. After heating, the motor 11 drives the rack 14 to slide along the slide groove 13, allowing it to exit the heat preservation box 16. By setting the motor 11, gear 12, and rack 14, the connector is moved on the worktable 1, lifting the connector. Then, the heating base plate 15 and heating top plate 17 are set to heat both sides of the connector simultaneously, making the connector more evenly heated and accelerating the heat treatment process. The connector is installed between the fixed frames 2. First, the second clamping block 23 is pulled, lifting the second clamping block 23 and stretching the spring 24. Then, the connector is placed on the first clamping block 22. Then, the second clamping block 23 is released, the spring 24 rebounds, and the second clamping block 23 and the first clamping block 22 clamp the connector. The telescopic rod 21 adjusts the width of the connector. Adaptive adjustment; by setting telescopic rod 21, first clamp 22 and second clamp 23, the connector is suspended and supported. The telescopic rod 21 can adjust the position of the first clamp 22 and second clamp 23. When fixing different connectors, ensure that the connector is placed in the center of the workbench 1 so that the connector is heated better. The curtain 3 covers both sides of the heat preservation box 16 to reduce the flow of hot air inside the heat preservation box 16 to the outside during the heat treatment process, which would cause rapid temperature loss and reduce the phenomenon of poor heat treatment effect on the connector. There is a heat preservation process in the heat treatment. After the heating bottom plate 15 and heating top plate 17 are closed, the heat insulation cotton 31 wraps the outside of the heat preservation box 16 to reduce the rate of heat loss. The rack 14 enters the workbench 1. When exiting the insulation box 16, the curtain 3 obstructs the movement of the rack 14. During the movement of the rack 14, the protrusion 41 has priority to contact the curtain 3 and pry open the gap. As the rack 14 advances, the pried curtain 3 will widen outward along the shape of the guide rod 4, leaving a gap for the connector to enter and exit. After the connector is heated and insulated in the insulation box 16, it enters the cooling plate 5. The external air pipe 51 is connected to the cold air. The cold air is emitted from the external air pipe 51 and acts on the connector to cool it. The rack 14 slides in the slide groove 13, and the end inevitably impacts. The pad 6 protects and buffers the rack 14 to reduce the impact of the rack 14 on the slide groove 13, which may cause damage to the rack 14 or the slide groove 13.
