Technical Field

[0001] This application relates to the field of heating furnaces, and more particularly to a heating furnace for processing plastic mold steel. Background Technology

[0002] In the production of plastic mold steel, heating furnaces are typically used for heating. A heating furnace is an industrial device used to heat materials or workpieces to a specific temperature. It transfers heat energy to the object being heated by burning fuel or using energy sources such as electricity or electromagnetic induction to meet process requirements.

[0003] The heating furnace mainly consists of a furnace body, heating elements, and a conveyor belt. The heating elements are installed inside the furnace body, and the conveyor belt passes through the furnace body. During operation, the workpiece is placed on the conveyor belt, which transports the workpiece into the furnace body for heating by the heating elements, and then sends it out to the outside of the furnace body.

[0004] When the workpiece is transported on the conveyor belt, it is heated in the same state. The side of the workpiece facing upwards is heated at a higher temperature than the side facing downwards, resulting in uneven heating of the workpiece and poor heat treatment effect. Utility Model Content

[0005] To address the problem of uneven heating and poor heat treatment results caused by one side of the workpiece being heated during transportation, this application provides a heating furnace for processing plastic mold steel.

[0006] The heating furnace for processing plastic mold steel provided in this application adopts the following technical solution:

[0015] Optionally, the end of the rotating rod opposite to the first mounting bracket is rotatably connected to a plug, and the second mounting bracket is provided with a slot, through which the plug is inserted and connected to the second mounting bracket.

[0016] By adopting the above technical solution, the rotating rod is connected to the second mounting bracket through the cooperation of the insert block and the slot, which facilitates the installation and disassembly of the rotating rod, and is beneficial for later maintenance and replacement of the rotating rod. At the same time, it ensures that the rotating rod can rotate stably to drive the workpiece to rotate.

[0017] Optionally, the first mounting bracket and the second mounting bracket are distributed parallel to each other. The first mounting bracket is provided with a first guide rod, and the second mounting bracket is provided with a second guide rod. The first guide rod has a guide groove, and the second guide rod is slidably connected to the first guide rod through the guide groove.

[0018] By adopting the above technical solution, the first mounting bracket and the second mounting bracket can slide relative to each other through the cooperation of the first guide rod and the second guide rod, which enhances the stability and adjustment flexibility of the overall structure of the mounting bracket and makes it easier to adapt to the placement requirements of workpieces of different sizes.

[0019] Optionally, the plug rod is threadedly connected to both the first mounting bracket and the second mounting bracket.

[0020] By adopting the above technical solution, the height of the first mounting bracket and the second mounting bracket can be adjusted by rotating the plug rod, which is suitable for rotating support of workpieces with different pipe diameters.

Under the action of the second gear, multiple rotating rollers rotate synchronously, driving the workpiece to rotate, making the workpiece heat more evenly.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The rotating roller drives the workpiece to rotate, ensuring that the workpiece is heated evenly during the heating process, resulting in better heat treatment effect;

[0035] The present application will be further described in detail below with reference to the accompanying drawings.

[0036] This application discloses a heating furnace for processing plastic mold steel, referring to... Figure 1 and Figure 2 The furnace body includes a furnace body 1, a linear drive mechanism 2, a transport vehicle 3, and a mounting frame 4. The furnace body 1 has through openings 11 on both sides along its length. The linear drive mechanism 2 is located inside the furnace body 1 and is used to drive the transport vehicle 3 to move in and out of the furnace body 1 along the direction of the openings 11. The mounting frame 4 is located on the transport vehicle 3 and is used to place the workpiece 5. The transport vehicle 3 is equipped with a rotating roller 31 for driving the workpiece 5 to rotate.

[0037] Reference Figure 1 and Figure 2 The furnace body 1 is rectangular in shape. The openings 11 on both sides of the furnace body 1 allow the transport vehicle 3 to enter and exit. The furnace body 1 is equipped with heating elements, which include several parallel heating tubes 12. The heating tubes 12 are located on the top wall of the furnace body 1 and are evenly distributed along the length of the furnace body 1. The heating tubes 12 are heated by resistance wire.

[0038] During operation, the workpiece 5 is placed on the mounting frame 4, and the linear drive mechanism 2 drives the transport vehicle 3 to move into the furnace body 1. The heating element heats the workpiece 5. During the heating process, the rotating roller 31 drives the workpiece 5 to rotate. The workpiece 5 rotates and is heated evenly, resulting in a better heat treatment effect.

[0039] Reference Figure 1 and Figure 2The linear drive mechanism 2 includes a guide rail 21, a lead screw 22, and a motor 23. The guide rail 21 is located inside the furnace body 1 and distributed along the direction of the two side openings 11. The two ends of the guide rail 21 are located outside the furnace body 1. The lead screw 22 is rotatably mounted on the guide rail 21. The motor 23 is located at one end of the guide rail 21. The lead screw 22 is connected to the output shaft of the motor 23. A guide block 24 is slidably mounted on the guide rail 21 and threadedly connected to the lead screw 22. A guide rod 25 is provided on the guide rail 21, and the guide block 24 is slidably connected to the guide rod 25. The transport vehicle 3 is connected to the guide block 24, thereby controlling the sliding of the guide block 24 on the guide rail 21 when the motor 23 drives the lead screw 22 to rotate, which in turn drives the transport vehicle 3 connected to the guide block 24 to move, ensuring that the transport vehicle 3 can enter and exit the furnace body 1 according to a predetermined path, facilitating the transport of the workpiece 5.

[0040] Reference Figure 2 and Figure 3 Five rotating rollers 31 are arranged in parallel to each other. Both ends of the rotating rollers 31 are mounted on the transport vehicle 3 via bearings. A first gear 32 is coaxially fixedly connected to each rotating roller 31. A second gear 33 meshes between two adjacent first gears 32. The second gear 33 is rotatably mounted on the transport vehicle 3. A rack 34 is provided on one side of the guide rail 21 and is fixed to the side of the guide rail 21, aligned with the length direction of the guide rail 21. A third gear 35 is rotatably mounted on the transport vehicle 3. The third gear 35 meshes with one side of the rack 34 and with one of the first gears 32. When the transport vehicle 3 moves, the meshing of the rack 34 and the third gear 35 drives the first gear 32 to rotate, which in turn drives the rotating rollers 31 to rotate. Under the action of the second gear 33, multiple rotating rollers 31 rotate synchronously, causing the workpiece 5 to rotate, resulting in more uniform heating of the workpiece 5.

[0041] Reference Figure 3 and Figure 4 The mounting frame 4 includes a horizontally arranged first mounting frame 41 and a second mounting frame 42. Both the first mounting frame 41 and the second mounting frame 42 are detachably mounted on the transport vehicle 3. The first mounting frame 41 and the second mounting frame 42 are distributed along the length of the transport vehicle 3 and are arranged opposite each other on both sides of the width of the transport vehicle 3. The first mounting frame 41 is provided with a first guide rod 411 that is perpendicular to the first mounting frame 41, and the second mounting frame 42 is provided with a second guide rod 421 that is perpendicular to the second mounting frame 42. The first guide rod 411 is provided with a guide groove 4111, and the second guide rod 421 is slidably connected to the first guide rod 411 through the guide groove 4111. The first mounting frame 41 and the second mounting frame 42 achieve relative sliding through the cooperation of the first guide rod 411 and the second guide rod 421, which enhances the stability and adjustment flexibility of the overall structure of the mounting frame 4 and facilitates the placement of workpieces 5 of different sizes.

[0042] Reference Figure 3and Figure 4 The first mounting bracket 41 and the second mounting bracket 42 are vertically equipped with insertion rods 43. The transport vehicle 3 has an insertion slot on its upward-facing side. The downward-facing end of the insertion rod 43 connects to the transport vehicle 3 via the insertion slot, facilitating quick assembly and disassembly of the first mounting bracket 41 and the second mounting bracket 42. The insertion rod 43 is threaded to both the first mounting bracket 41 and the second mounting bracket 42. Rotating the insertion rod 43 adjusts the height of the first mounting bracket 41 and the second mounting bracket 42, making it suitable for rotating and supporting workpieces 5 of different pipe diameters.

[0043] Reference Figure 3 and Figure 4 A rotating rod 44 for driving the workpiece 5 to rotate is rotatably mounted on the first mounting rod. The rotating rod 44 is perpendicular to the first mounting frame 41 and is located on the upper side of the rotating roller 31 and parallel to the rotating roller 31. There are four rotating rods 44, which are staggered with the rotating roller 31. The rotating roller 31 drives the workpiece 5 to rotate. With the rotating rods 44 on the upper side that are parallel to it and staggered, the workpiece 5 is supported and driven to rotate more stably, so that the workpiece 5 is heated more evenly during the heating process. The end of the rotating rod 44 away from the first mounting frame 41 is rotatably connected to the insert block 441. The second mounting frame 42 is provided with a slot 4211. The insert block 441 is inserted and connected to the second mounting frame 42 through the slot 4211, which facilitates the installation and removal of the rotating rod 44, and is beneficial for later maintenance and replacement of the rotating rod 44. At the same time, it ensures that the rotating rod 44 can rotate stably to drive the workpiece 5 to rotate.

[0044] The implementation principle of a heating furnace for processing plastic mold steel according to an embodiment of this application is as follows: This embodiment solves the problem of uneven heating of the workpiece 5 in traditional heating furnaces by setting up a movable transport vehicle 3 and a mounting frame 4 that can drive the workpiece 5 to rotate. The linear drive mechanism 2 precisely controls the movement of the transport vehicle 3, so that the workpiece 5 can accurately reach the heating position. The cooperative design of the rotating roller 31 and the rotating rod 44 allows the workpiece 5 to rotate continuously during the heating process, so that all parts can fully contact the heat in the furnace, which greatly improves the heating uniformity of the workpiece 5 and enhances the heat treatment effect. At the same time, the detachable and adjustable structure of the mounting frame 4 facilitates the loading and unloading of the workpiece 5 and the adaptability to workpieces 5 of different sizes, improving the practicality and versatility of the heating furnace, which has significant improvements and advantages compared with traditional heating furnaces.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
