[0022] Reference Figure 1 and Figure 2The utility model is a heating device for forging dies of railway parts. The main structure includes a heating box 1 and a track 2. A heating element is arranged inside the heating box 1. The surface of the shell-shaped heating box 1 is wrapped with a heat insulation layer to realize the heating operation of the mold in the heating box 1. The track 2 is laid under the heating box 1 and extends outward. A carrying trolley 3 is arranged on the track 2. The carrying trolley 3 can move along the track 2. An inlet 4 is arranged on one side of the heating box 1. The inlet 4 runs through the side of the heating box 1. The carrying trolley 3 enters the interior of the heating box 1 after passing through the inlet 4. Such a structure allows the mold to be heated before heating. The mold is hoisted and placed on the carrying trolley 3 in advance by using equipment such as a crane, and then the carrying trolley 3 moves along the track 2 to automatically pass through the entrance 4 to enter and exit the heating box 1, which reduces the frequency of direct human operation on the mold, reduces possible safety hazards, and makes the movement of the mold more convenient, greatly reduces the difficulty of movement, and improves the convenience of moving the mold with a large volume and weight during the heating process. The bottom of the carrying trolley 3 is provided with a plurality of rollers 5 through bearings, and the rollers 5 are connected to the track 2 in a rolling manner, so that the resistance of the carrying trolley 3 when moving along the track 2 is smaller, and the carrying capacity is improved. In order to ensure the smoothness of the trolley 3 entering the heating box 1, a power component for driving the roller 5 to rotate is provided at the bottom of the trolley 3. The power component is used to drive the roller 5 to rotate automatically, which improves the automation degree of the mold entering and exiting the heating box 1, and further reduces the workload and potential risks of manual operation. A bracket 6 is fixed at the entrance 4 by welding or bolts. The upper edge of the bracket 6 is vertically slidably connected with an insulation door panel 7 used in conjunction with the entrance 4. The insulation door panel 7 is wrapped with insulation cotton and other materials to seal the entrance 4, avoid heat dissipation during heating, ensure heating efficiency, and reduce potential damage caused by heat dissipation. In order to prevent the risk of scalding, a convex strip 8 is welded or integrally formed on the outer side of the heat-insulating door panel 7, and a limiting frame 9 is welded or bolted to the end of the carrying trolley 3. A limiting column 10 is provided on the limiting frame 9 for cooperating with the convex strip 8. In this structure, when the heat-insulating door panel 7 is lowered to close the entrance 4 during heating, the limiting column 10 on the limiting frame 9 is moved, so that the limiting column 10 cooperates with the convex strip 8 to limit the vertical position of the heat-insulating door panel 7, thereby effectively preventing the heat-insulating door panel 7 from being accidentally opened during heating, reducing possible safety hazards, and further improving the safety of the heating operation.

[0023] Preferably, refer to Figure 4 A rim 11 is welded or integrally formed on the inner side of the roller 5, and the diameter of the rim 11 is larger than the diameter of the roller 5. The rim 11 contacts the inner side of the track 2. Such a structure can limit the carrying trolley 3 on the track 2 by setting the rims 11 on the rollers 5 on both sides, thereby avoiding derailment of the carrying trolley 3 during movement, and further ensuring the safety and stability of the mold entering and exiting the heating box 1.

[0024] Preferably, refer to Figure 3 The power assembly includes a driving shaft 12 and a driven shaft 13, both of which are rotatably connected to the bottom of the carrying trolley 3 through bearings. The driving shaft 12 rotates under the drive of the motor, and the rollers 5 are symmetrically welded or bolted to the two ends of the driven shaft 13. A meshing bevel gear 14 is provided between the driving shaft 12 and the driven shaft 13. Such a structure uses the driving shaft 12 to simultaneously drive the rollers 5 at both ends of the driven shaft 13 to rotate, which reduces the complexity of the power assembly, improves the utilization rate of the power system, and improves the synchronization of the rotation of the rollers 5 on both sides, so that the movement of the carrying trolley 3 on the track 2 is smoother and more stable.

[0025] Preferably, guide grooves 15 are symmetrically provided on both sides of the bracket 6, and the guide grooves 15 are formed by the inner surface of the bracket 6 being recessed inwardly. Guide columns 16 welded or bolted and screws 17 rotated through bearings are respectively provided in the two guide grooves 15, and the screws 17 are driven to rotate by a motor. Sliders 18 are symmetrically welded or bolted on both sides of the heat-insulating door panel 7, and the screw 17 passes through one of the slides 18 and is threadedly connected thereto, and the guide column passes through the other slide 18 and is slidably connected thereto. Such a structure utilizes the rotation of the screw 17 to drive the heat-insulating door panel 7 to automatically slide up and down along the guide columns 16 and the guide grooves 15, thereby realizing automatic opening and closing control of the heat-insulating door panel 7, avoiding direct contact between the operator and the high-temperature internal environment of the heating box 1, and ensuring the safety of the heating process.

[0026] Preferably, the limit column 10 passes through the limit frame 9 and is threadedly connected thereto. After the limit column 10 moves, it is located above the convex strip 8. Such a structure only requires rotating the limit column 10 to drive the limit column 10 to move above the convex strip 8 under the action of the threaded connection. The operation is convenient, and the outer side temperature of the insulation door panel 7 is relatively low, so that no burns or other injuries will be caused during operation, thereby improving the convenience of operating the limit column 10.

[0027] Preferably, refer to Figure 5 An insulating placement platform 19 is welded or bolted on the carrying trolley 3, and the mold is placed on the insulating placement platform 19, so that the carrying trolley 3 is not easy to directly contact the high-temperature internal environment of the heating box 1, reducing the possibility of heat dissipation through the carrying trolley 3, and the bottom of the insulating door panel 7 is in contact with the top of the insulating placement platform 19, so that after the insulating door panel 7 is closed, the contact position between the bottom and the insulating placement platform 19 is better sealed, ensuring the stability of the internal temperature of the heating box 1 and improving the heating efficiency. The interior of the heating box 1 is provided with a plurality of heating tubes 20 surrounding the outside of the insulating placement platform 19. The arrangement of the plurality of heating tubes 20 can perform uniform and good heating treatment on various positions of the mold on the insulating placement platform 19, ensuring the uniformity and efficiency of heating.

[0028] Working principle: The structure of the utility model is provided with a track 2 and a heating box 1. The carrying trolley 3 on the track 2 passes through the entrance 4 under the action of the power assembly and enters the interior of the heating box 1 to achieve the heating operation of the mold on the carrying trolley 3. During heating, the heat insulation door plate 7 slides downward along the bracket 6 to close the entrance 4, so that the operation of the mold entering and exiting the heating box 1 is smoother, which greatly simplifies the steps of manual operation, avoids the heat dissipation during the heating process, and ensures the convenience and safety of heating the mold; the bottom of the carrying trolley 3 is provided with a plurality of rollers that roll in contact with the track 2 5. The power assembly is used to drive the roller 5 to rotate, so that the resistance of the carrying trolley 3 entering the heating box 1 is smaller, and the smoothness of entry and exit is improved. At the same time, a convex strip 8 is provided on the outer side of the heat insulation door panel 7, and a limiting frame 9 is provided at the end of the carrying trolley 3. The limiting frame 9 is provided with a limiting column 10 used in conjunction with the convex strip 8. When the heat insulation door panel 7 is lowered to close the entrance 4, such a structure limits the position of the heat insulation door panel 7 by moving the limiting column 10 to cooperate with the convex strip 8, thereby avoiding burns caused by accidental opening of the heat insulation door panel 7 when heating is not completed, and further improving the safety of the mold heating process.
