Description

Technical Field

[0001] This utility model belongs to the field of mold tempering technology, specifically relating to a uniform heating double tempering pipe structure. Background Technology

[0002] Some molds require tempering treatment through a tempering pipeline during production to eliminate thermal stress at the welded areas, restore the mold's original structure and performance, and improve its service life and precision. Specifically, the tempering pipeline heats the mold to a specific temperature, holds it for a period of time, and then cools it. This eliminates thermal stress generated during welding, preventing mold deformation and cracking.

[0003] The existing method generally involves placing the mold in a heating furnace for tempering. To ensure that the mold is heated evenly, multiple tempering pipes need to be distributed in a ring on the inner wall of the heating furnace, which results in high mold tempering costs. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed uniform heating double tempering pipe structure in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A uniform heating double tempering pipe structure includes two tempering pipe bodies symmetrically installed in the inner cavity of a heating furnace. An electric heating wire is installed inside each tempering pipe body. A connecting plate is provided between both ends of the two tempering pipe bodies, and the ends of the connecting plates are respectively fixed to the two tempering pipe bodies. One of the connecting plates has a wire-passing hole. A rotary joint is installed on the outer wall of the heating furnace near the wire-passing hole. A wire is passed through the wire-passing hole, and both ends of the wire are electrically connected to the electric heating wire and the rotary joint, respectively. A motor is fixedly installed on the outer wall of the heating furnace at the end away from the rotary joint. The output end of the motor passes through the outer wall of the heating furnace end and is fixed to the middle section of the connecting plate away from the rotary joint. A tempering container is provided between the two tempering pipe bodies, with both ends rotatably connected to the two connecting plates. A sealing structure can also be detachably connected to the top of the heating furnace.

[0007] As a further optimization of this utility model, the tempering pipe body has a circular tube structure, and a gap is left between the outer wall of the tempering pipe body and the outer wall of the tempering container.

[0008] As a further optimization of this utility model, the tempering container includes a tempering box with a rectangular box-shaped structure. The tempering box has through holes on its side wall and bottom wall. Both ends of the tempering box are fixedly connected to connecting shafts, and the ends of the two connecting shafts away from the tempering box are respectively rotatably connected to the two connecting plates.

[0009] As a further optimization of this utility model, the sealing structure includes a furnace cover disposed above the heating furnace, and both the furnace cover and the heating furnace extend outward to form a mounting plate. The mounting plate has threaded holes, and fixing bolts are screwed into the threaded holes.

[0010] As a further optimization of this utility model, two symmetrically arranged handles are fixedly installed on the upper surface of the furnace cover. The outer surface of each handle is covered with a rubber sleeve, and the rubber sleeve has anti-slip texture.

[0011] As a further optimization of this utility model, both the heating furnace and the furnace cover are double-layered structures, with an insulation cavity formed between the two layers, and the insulation cavity is filled with high-temperature resistant insulation material.

[0012] The beneficial effects of this utility model are as follows: When in use, the mold is placed inside the tempering box, and the rotary joint is connected to an external power source, so that the electric heating wire is energized to heat and temper the mold. At the same time, the user can start the motor, which drives the connecting plate to rotate, thereby causing the electric heating wires in the two tempering pipe bodies to slowly rotate around the tempering box. This achieves uniform heating of the mold through the double tempering pipe structure, and avoids the problem of high mold tempering costs caused by the need for multiple tempering pipes to be distributed in a ring on the inner wall of the existing heating furnace.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example

[0021] like Figure 1 - Figure 5 As shown, a uniform heating double tempering pipe structure includes two tempering pipe bodies 2 symmetrically installed in the inner cavity of the heating furnace 1, and two sets of support legs 10 symmetrically installed on the outer wall of the heating furnace 1 to support the bottom of the heating furnace 1 until it is detached from the ground.

[0022] An electric heating wire 3 is installed inside the tempering pipe body 2. A connecting plate 4 is provided between the two ends of the two tempering pipe bodies 2. The ends of the connecting plate 4 are fixed to the two tempering pipe bodies 2 respectively. A wire hole is opened in one of the connecting plates 4. A rotary joint 6 is installed on the outer wall of the heating furnace 1 near the wire hole. A wire 5 is passed through the wire hole. The two ends of the wire 5 are electrically connected to the electric heating wire 3 and the rotary joint 6 respectively. The setting of the rotary joint 6 allows the electric heating wire 3 to be electrically connected to an external power source through the rotary joint 6 to supply power to the electric heating wire 3. At the same time, it does not affect the rotation of the tempering pipe body 2 in the inner cavity of the heating furnace 1.

[0023] A motor 7 is fixedly installed on the outer wall of the end of the heating furnace 1 away from the rotary joint 6. The output end of the motor 7 passes through the outer wall of the end of the heating furnace 1 and is fixed to the middle section of the connecting plate 4 away from the rotary joint 6. When the user starts the motor 7, the connecting plate 4 can be rotated through the output end of the motor 7, thereby driving the tempering pipe body 2 to rotate inside the heating furnace 1.

[0024] A tempering container is provided between the two tempering pipe bodies 2, with both ends rotatably connected to two connecting plates 4 respectively. The tempering container includes a tempering box 8 with a rectangular box structure. Through holes are provided on the side wall and bottom wall of the tempering box 8 to facilitate heat conduction. Both ends of the tempering box 8 are fixedly connected to connecting shafts 9. The ends of the two connecting shafts 9 away from the tempering box 8 are rotatably connected to the two connecting plates 4 respectively. The tempering box 8 is set up to hold the mold that needs to be tempered. When the mold is placed in the tempering box 8, the tempering box 8 can remain stationary when the connecting plates 4 rotate due to the influence of the weight of the mold.

[0025] The top of the heating furnace 1 is also detachably connected to a sealing structure. The sealing structure includes a furnace cover 11 set above the heating furnace 1. The furnace cover 11 and both sides of the heating furnace 1 extend outward to form mounting plates 12. The mounting plates 12 are provided with threaded holes 13. Fixing bolts 14 are screwed into the threaded holes 13, so that the furnace cover 11 can be detachably connected to the heating furnace 1 through the mounting plates 12 and fixing bolts 14, sealing the opening at the top of the heating furnace 1, minimizing heat loss, and improving the heating efficiency of the mold.

[0026] Two symmetrically arranged handles 15 are fixedly installed on the upper surface of the furnace cover 11. Both handles 15 are covered with rubber sleeves 16 on their outer surfaces. The rubber sleeves 16 have anti-slip textures. The handles 15 are designed to make it easy to open the furnace cover 11. The rubber sleeves 16 on the handles 15 are designed to prevent burns and to minimize the risk of burns when opening the furnace cover 11.

[0027] Both the heating furnace 1 and the furnace cover 11 are double-layered structures, with an insulation cavity 17 formed between the two layers. The insulation cavity 17 is filled with high-temperature resistant insulation material. By filling the insulation cavity 17 with insulation material, the insulation effect of the heating furnace 1 is improved, heat loss is avoided, and heat insulation is maximized to prevent the outer surface temperature of the heating furnace 1 and the furnace cover 11 from becoming too high.

[0028] It should be noted that, in the use of this uniform heating double tempering pipe structure, firstly, the furnace cover 11 is removed by screwing the fixing bolt 14, then the mold to be tempered is placed inside the tempering box 8, then the furnace cover 11 is re-fixed, and the rotary joint 6 is connected to an external power source to supply power to the electric heating wire 3. After the electric heating wire 3 is powered on, it can heat and temper the mold contained in the tempering box 8 through the principle of heat conduction. At the same time, the user can start the motor 7, which drives the connecting plate 4 to rotate, thereby driving the electric heating wire 3 in the two tempering pipe bodies 2 to slowly rotate around the tempering box 8, so as to achieve uniform heating of the mold through the double tempering pipe structure, and avoid the problem of high mold tempering cost caused by the need for multiple tempering pipes to be distributed in a ring on the inner wall of the existing heating furnace 1.

[0029] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
