Description

Technical Field

[0001] This utility model relates to the field of steel casting technology, specifically to a heat treatment device for the production of metal steel castings. Background Technology

[0002] Heat treatment refers to a metal heat treatment process in which the chemical composition and structure of a metal material are changed on its surface or inside by means of heating, holding and cooling in the solid state, so as to obtain the desired properties. This process usually requires the use of production heat treatment equipment. Traditional heat treatment equipment includes box furnaces, pit furnaces, salt bath furnaces, etc. These devices provide the required high-temperature environment by electric heating or burning fuel. With the advancement of technology, many improved heat treatment technologies and equipment have emerged, such as vacuum heat treatment, induction heating heat treatment, and laser heat treatment.

[0003] However, current heat treatment equipment for metal steel casting production still has the following shortcomings: most induction heating heat treatment equipment still adopts the method of hand-holding the steel and letting it pass through the induction heating coil to complete the heating treatment. This method has many disadvantages. First, the operation process is not convenient enough. Second, because it is necessary to hold the workpiece for a long time, not only is the labor intensity high, but it is also easy to cause operator fatigue, thereby reducing work efficiency. More importantly, this operation method has certain safety hazards and is prone to causing safety accidents such as burns and accidental contact. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a heat treatment device for the production of metal steel castings, which can improve the convenience and safety of the device through mechanical clamping.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat treatment device for producing metal steel castings, comprising an induction heat processor and an induction heating coil mounted on the induction heat processor. A groove is formed on the front surface of the induction heat processor in the area where the induction heating coil is located. A driving component is slidably connected in the groove. A clamping block is mounted on the driving component. A loading hole is formed on the side wall of the clamping block, which is adapted to the position and shape of the induction heating coil. Threaded grooves are formed on both the upper and lower surfaces of the clamping block, and extrusion bolts are threaded into both of the threaded grooves.

[0006] Furthermore, the driving component comprises a T-shaped slide bar, a mounting slider, a connecting rod, and a mounting rod. A limiting sliding hole communicating with the slide bar is provided at the end of the slide groove furthest from the induction heating coil. The T-shaped slide bar is a combination of a rectangular rod and a column. The outer wall of the column of the T-shaped slide bar is slidably connected to the inner wall of the limiting sliding hole. The rectangular rod of the T-shaped slide bar is located outside the induction heat processor. The mounting slider is slidably connected within the slide groove. The side wall of the mounting slider is fixedly connected to one end of the column of the T-shaped slide bar. The surface of the mounting slider near the clamping block is fixedly connected to one end of the connecting rod. A rotating component is mounted on the other end of the connecting rod. The rotating component is fixedly connected to one end of the mounting rod, and the other end of the mounting rod is fixedly connected to the side wall of the clamping block.

[0007] Furthermore, the rotating component is a disc and a cylinder. The connecting rod has a cylindrical groove at one end near the mounting rod, and a disc-shaped groove communicating with the cylindrical groove is formed inside the connecting rod. The annular outer wall of the disc is rotatably connected to the annular inner wall of the disc-shaped groove, and the annular outer wall of the cylinder is rotatably connected to the annular inner wall of the cylindrical groove. One end of the disc is fixedly connected to one end of the cylinder, and the other end of the cylinder is fixedly connected to the mounting rod. A T-shaped auxiliary rotating rod is fixedly connected to the side wall of the clamping block away from the mounting rod.

[0008] Furthermore, a heat insulation sleeve is fixedly connected to the inner wall of the loading hole, and an elastic sleeve is fixedly connected to the inner wall of the heat insulation sleeve.

[0009] Furthermore, an installation ring is fixedly connected to the annular outer wall of one end of the mounting rod near the clamping block, and a fastening bolt is threadedly connected to the other end of the mounting ring away from the clamping block on the circumference of the mounting rod. The fastening bolt passes through the mounting ring to the clamping block for bolt fastening.

[0010] Furthermore, the inner wall of the groove, the inner wall of the limiting sliding hole, the outer wall of the T-shaped sliding rod column, and the outer wall of the mounting slider are all smoothly formed.

[0011] Furthermore, the outer wall of the disc, the outer wall of the cylinder, the outer wall of the T-shaped auxiliary rotating rod, the inner wall of the disc-shaped groove, the inner wall of the cylindrical groove, and the outer wall of the T-shaped sliding rod rectangular rod are all provided with anti-slip textures.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, through the cooperation of a clamping block, a loading hole, and extrusion bolts, allows the steel to be processed to be placed into the loading hole on the clamping block. By tightening the upper and lower extrusion bolts, the steel is positioned and fixed in the center of the loading hole. Subsequently, the clamping block is slid by a driving component, conveniently feeding the steel into the induction heating coil for heating. This structure not only simplifies the heating process, reduces the labor intensity of operators, and improves work efficiency, but also ensures that operators maintain a safe distance from the high-temperature steel, reducing the probability of safety accidents and improving the overall safety of the equipment. The structure is simple, easy to operate, and highly practical.

[0014] 2. This utility model achieves multi-directional heating treatment of steel by setting up a disc, a cylinder, and a T-shaped auxiliary rotating rod in cooperation. After one side of the steel in the loading hole is heated, the operator can hold the T-shaped auxiliary rotating rod and rotate the clamping block to switch to the other side of the unheated part for continued heat treatment. Throughout the operation, the T-shaped auxiliary rotating rod must be held at all times to prevent the clamping block from shaking or colliding with the induction heating coil, thereby improving the stability and safety of operation. In addition, the device is also equipped with an installation ring and fastening bolts to facilitate the easy disassembly of the clamping block and its accessories, which is convenient for later maintenance and replacement. At the same time, with the synergistic effect of the heat insulation sleeve and the elastic sleeve, not only is the adaptability of the clamping block to steel of different shapes improved, but the heat insulation effect is also enhanced, reducing heat conduction to the operator and further improving the safety of equipment use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] like Figures 1 to 6 As shown, a heat treatment apparatus for producing metal steel castings includes an induction heat processor 1 and an induction heating coil 2 mounted on the induction heat processor 1. A groove 3 is formed on the front surface of the induction heat processor 1 in the area where the induction heating coil 2 is located. A driving component is slidably connected in the groove 3. A clamping block 9 is mounted on the driving component. A loading hole 13 is formed on the side wall of the clamping block 9, which is adapted to the position and shape of the induction heating coil 2. Threaded grooves 11 are formed on both the upper and lower surfaces of the clamping block 9. Extrusion bolts 12 are threadedly connected in both threaded grooves 11.

[0024] like Figures 1 to 6 As shown, in the heat treatment device for producing metal steel castings of this utility model, the steel to be treated is placed into the loading hole 13 on the clamping block 9, and the steel is positioned and fixed in the center of the loading hole 13 by tightening the upper and lower extrusion bolts 12. Then, with the help of the driving component, the clamping block 9 is driven so that the steel on it can be easily fed into the induction heating coil 2 for heat treatment. This structure not only realizes the convenient operation of the heating process, reduces the labor intensity of the operators, and improves the work efficiency, but also keeps the operators at a certain safe distance from the high-temperature steel, reduces the probability of safety accidents, and improves the overall safety of the equipment.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, the driving components are a T-shaped slide bar 5, a mounting slider 6, a connecting rod 7, and a mounting rod 8. The end of the slide groove 3 away from the induction heating coil 2 has a limiting sliding hole 4 that communicates with the slide groove 3. The T-shaped slide bar 5 is a combination of a rectangular rod and a column. The outer wall of the column of the T-shaped slide bar 5 is slidably connected to the inner wall of the limiting sliding hole 4. The rectangular rod of the T-shaped slide bar 5 is located outside the induction heat processor 1. The mounting slider 6 is slidably connected inside the slide groove 3. The side wall of the mounting slider 6 is fixedly connected to one end of the column of the T-shaped slide bar 5. The surface of the mounting slider 6 near the clamping block 9 is fixedly connected to one end of the connecting rod 7. The other end of the connecting rod 7 is equipped with a rotating component, which is fixedly connected to one end of the mounting rod 8. The other end of the mounting rod 8 is fixedly connected to the side wall of the clamping block 9.

[0026] Specifically, when using the device, the user holds the T-shaped slide bar 5 and then pushes the T-shaped slide bar 5, causing the mounting slider 6, connecting rod 7, mounting rod 8 and clamping block 9 on the T-shaped slide bar 5 to slide together into the heat treatment area inside the induction heating coil 2. Through the mechanical manual sliding drive, the labor intensity of the operator is reduced, while also realizing the manual and rapid adjustment and intervention of the steel heat treatment process, thus improving the operational flexibility.

[0027] like Figure 5 and Figure 6 As shown, the rotating parts are a disc 20 and a cylinder 21. A cylindrical groove 19 is provided at one end of the connecting rod 7 near the mounting rod 8. A disc groove 18 communicating with the cylindrical groove 19 is provided inside the connecting rod 7. The annular outer wall of the disc 20 is rotatably connected to the annular inner wall of the disc groove 18. The annular outer wall of the cylinder 21 is rotatably connected to the annular inner wall of the cylindrical groove 19. One end of the disc 20 is fixedly connected to one end of the cylinder 21. The other end of the cylinder 21 is fixedly connected to the mounting rod 8. A T-shaped auxiliary rotating rod 10 is fixedly connected to the side wall of the clamping block 9 away from the mounting rod 8.

[0028] Specifically, after one side of the steel in the loading hole 13 has been heated, the operator can hold the T-shaped auxiliary rotating rod 10 and rotate the clamping block 9 with the cooperation of the disc 20 and the cylinder 21 to switch to the other side of the unheated part for heat treatment. Throughout the operation, the T-shaped auxiliary rotating rod 10 must be held at all times to prevent the clamping block 9 from shaking or colliding with the induction heating coil 2 by manual fixation, thereby improving the stability of operation and the safety of operation.

[0029] like Figure 3 As shown, a heat insulation sleeve 14 is fixedly connected to the inner wall of the loading hole 13, and an elastic sleeve 15 is fixedly connected to the inner wall of the heat insulation sleeve 14.

[0030] Specifically, the synergistic effect of the heat insulation sleeve 14 and the elastic sleeve 15 not only improves the adaptability of the clamping block 9 to steel of different shapes, but also enhances the heat insulation effect, reduces heat conduction to operators, and further improves the safety of equipment use.

[0031] It is worth noting that the heat insulation sleeve 14 can be made of toughened ceramic heat insulation sleeve, while the elastic sleeve 15 can be made of high-temperature resistant fluororubber or silicone rubber elastic sleeve, which enhances the performance and service life of both.

[0032] like Figure 3 As shown, an installation ring 16 is fixed to the annular outer wall of the mounting rod 8 near the clamping block 9. The end of the mounting ring 16 away from the clamping block 9 is threaded with a fastening bolt 17 on the circumference of the mounting rod 8. The fastening bolt 17 passes through the mounting ring 16 to the clamping block 9 for bolt fastening.

[0033] Specifically, by unscrewing the fastening bolt 17, the mounting rod 8, the mounting ring 16 fixed to the outer wall of the mounting rod 8, the clamping block 9 and its accessories can be easily disassembled, facilitating later maintenance and replacement.

[0034] like Figure 1 and Figure 2 As shown, the inner wall of the slide groove 3, the inner wall of the limiting slide hole 4, the outer wall of the T-shaped slide rod 5 column, and the outer wall of the mounting slider 6 are all smoothly provided. By setting a smooth layer, frictional resistance can be reduced, making it easier for the user to send the steel into the induction heating coil 2 through the sliding drive component, thus improving the user experience.

[0035] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the outer wall of the disc 20, the outer wall of the cylinder 21, the outer wall of the T-shaped auxiliary rotating rod 10, the inner wall of the disc groove 18, the inner wall of the cylindrical groove 19, and the outer wall of the rectangular rod of the T-shaped slide rod 5 are all provided with anti-slip textures. By setting anti-slip textures, the frictional resistance can be increased, making it more stable during the process of rotating and changing the processing position of the steel. At the same time, after the change is completed, it is easier to hold the T-shaped auxiliary rotating rod 10 to limit the shaking of the clamping block 9, which can save more effort. In addition, it can also reduce the occurrence of hand slippage.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
