Description

Technical Field

[0001] This utility model relates to the technical field of high manganese and high chromium heat-resistant steel, specifically to a heat treatment device for high manganese and high chromium heat-resistant steel. Background Technology

[0002] Heat treatment of high-manganese and high-chromium heat-resistant steel is a process that involves heating, holding, and cooling the steel in its solid state in an appropriate manner to change its internal structure and obtain the desired properties. The main purpose of heat treatment is to improve the mechanical properties of the steel by changing its crystal structure and microstructure. The heat treatment equipment mainly consists of quenching furnaces and other similar devices.

[0003] Existing heat treatment equipment has the problem of making it inconvenient to place steel materials outside the quenching furnace;

[0004] The reason for this problem is that during the use of the quenching furnace, a metal mesh frame is needed to hold the steel material, and then the metal mesh frame is placed on the support inside the quenching furnace. However, the quenching furnace is relatively deep, and the placement of the metal mesh frame can easily create blind spots in the internal space of the quenching furnace, resulting in empty spaces near the support inside the quenching furnace. This reduces the amount of material that can be heat-treated in a single operation. If the support is moved out of the quenching furnace, the weight that the support can bear is limited, and moving it out of the furnace will cause the ends of the support to be subjected to greater pressure, resulting in bending and other problems, affecting the normal use of the support. Therefore, we propose a heat treatment device for high-manganese and high-chromium heat-resistant steel. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model proposes a heat treatment device for high manganese and high chromium heat-resistant steel, which solves the problem that existing heat treatment devices are inconvenient to place steel materials outside the quenching furnace.

[0006] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows: a heat treatment device for high manganese and high chromium heat-resistant steel, including a quenching furnace body, a support frame fixedly connected inside the quenching furnace body, a support mechanism provided outside the support frame, the support mechanism including an extension frame movably disposed outside the support frame, the extension frame being used to extend the support range of the support frame, a fixed frame movably disposed on the front side of the quenching furnace body, the fixed frame being used to support the end of the extension frame, a fixed block movably disposed outside the fixed frame, the fixed block being movably inserted into the end of the extension frame, the fixed block being used to fix the position between the extension frame and the fixed frame.

[0007] Preferably, the support frame has a sliding frame slidably connected inside, the extension frame is fixedly connected to the outside of the sliding frame, the end of the extension frame away from the sliding frame is fixedly connected to a connecting plate, the connecting plate is disposed outside the support frame, and the fixing block is movably inserted into the inside of the connecting plate.

[0008] Preferably, the quenching furnace body has an internal movable limit frame, and the fixed frame is fixedly connected to the outside of the limit frame.

[0009] Preferably, a sliding plate is slidably connected inside the fixing frame, a support plate is fixedly connected to the upper surface of the sliding plate, a support plate is fixedly connected to the top of the support plate, the outside of the connecting plate abuts against the outside of the support plate, and the fixing block is fixedly connected to the upper surface of the support plate.

[0010] Preferably, threaded rods are rotatably connected to both sides of the sliding plate, and mounting brackets are fixedly connected to both sides of the sliding plate. The threaded rods are rotatably connected to the outside of the mounting brackets, and a sliding block is threadedly connected to the outside of the threaded rods. A plug-in plate is fixedly connected to the outside of the sliding block, and the plug-in plate is movably inserted into the inside of the fixed bracket.

[0011] The beneficial effects of this utility model are:

[0012] The technical solution of this utility model involves extending the extension frame outside the quenching furnace, then moving the support plate upward to allow the fixing block to be inserted into the connecting plate. Rotating the threaded rod allows the insertion plate to be inserted into the long slot above the fixing frame. The extension frame is then pulled to a position convenient for placing metal materials. The extension frame is then moved back to the entrance of the quenching furnace body. Rotating the threaded rod allows the insertion plate to leave the fixing frame, and the fixing block to move away from the connecting plate. Finally, the extension frame is inserted into the upper position of the support frame inside the quenching furnace body. By extending the extension frame outside the quenching furnace body, the operating space and space utilization above the support frame are increased. Furthermore, when the extension frame extends outside the quenching furnace body, support plates and trays are used outside the quenching furnace body to support the end of the extension frame, increasing the stability during movement without affecting the normal use of the quenching furnace body's interior and exterior.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] This application provides a heat treatment device for high-manganese and high-chromium heat-resistant steel, which solves the problem that existing heat treatment devices are inconvenient for placing steel materials outside the quenching furnace.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] This utility model discloses a binding device for organizing archives.

[0025] According to the appendix Figure 1-6As shown, the furnace includes a quenching furnace body 1. A support frame 101 is fixedly connected inside the quenching furnace body 1. A support mechanism is provided outside the support frame 101. The support mechanism includes an extension frame 2, which is movably disposed outside the support frame 101. The extension frame 2 is used to extend the support range of the support frame 101. A fixed frame 201 is movably disposed on the front side of the quenching furnace body 1. The fixed frame 201 is used to support the end of the extension frame 2. A fixing block 203 is movably disposed outside the fixed frame 201. The fixing block 203 is movably inserted into the end of the extension frame 2. The fixing block 203 is used to fix the position between the extension frame 2 and the fixed frame 201.

[0026] The support frame 101 has a sliding frame 210 inside, and the extension frame 2 is fixedly connected to the outside of the sliding frame 210. The end of the extension frame 2 away from the sliding frame 210 is fixedly connected to a connecting plate 211. The connecting plate 211 is set outside the support frame 101. The fixing block 203 is movably inserted into the inside of the connecting plate 211. The quenching furnace body 1 has a limiting frame 212 inside, and the fixing frame 201 is fixedly connected to the outside of the limiting frame 212.

[0027] The fixed frame 201 has a sliding plate 204 inside, a support plate 202 is fixedly connected to the upper surface of the sliding plate 204, a support plate 205 is fixedly connected to the top of the support plate 202, the outside of the connecting plate 211 abuts against the outside of the support plate 205, and the fixing block 203 is fixedly connected to the upper surface of the support plate 205.

[0028] Threaded rods 207 are rotatably connected to both sides of the sliding plate 204, and mounting brackets 206 are fixedly connected to both sides of the sliding plate 204. The threaded rods 207 are rotatably connected to the outside of the mounting brackets 206, and a sliding block 208 is threadedly connected to the outside of the threaded rods 207. A plug-in plate 209 is fixedly connected to the outside of the sliding block 208, and the plug-in plate 209 is movably plugged into the inside of the fixed bracket 201.

[0029] By moving the position of the extension frame 2, the extension frame 2 will slide outside the support frame 101, while the sliding frame 210 will slide inside the support frame 101. The sliding frame 210 limits the movement of the extension frame 2, increasing the stability of the movement at the end of the extension frame 2. When the extension frame 2 and the connecting plate 211 extend outside the quenching furnace, rotating the threaded rod 207 drives the sliding block 208 to move, causing the insertion plate 209 to slide away from the interior of the fixed frame 201. Then, the support plate 202 moves upward, causing the support plate 202 to drive the support plate 205 and the fixed block 203 to move until the support plate 205 moves to the position below the connecting plate 211. After the fixed block 203 is inserted into the interior of the connecting plate 211, the threaded rod 207 is rotated again to insert the insertion plate 209 into the long slot above the fixed frame 201. Then, continue pulling the extension frame 2 to move it to a position convenient for placing metal materials. At this time, the fixed frame 201 and the support plate 202 will also move with the extension frame 2, and the limiting frame 212 will slide inside the quenching furnace body 1. Then, place the steel material inside the metal frame above the extension frame 2, thereby making reasonable use of the space above the extension frame 2, increasing the operating space above the extension frame 2, and increasing the efficiency of material placement. Then, move the extension frame 2 back to the entrance position of the quenching furnace body 1, rotate the threaded rod 207 to make the plug plate 209 leave the long slot above the fixed frame 201, and move the support plate 202 and the fixed block 203 away from the inside of the connecting plate 211. Finally, send the extension frame 2 into the position above the support frame 101 inside the quenching furnace body 1.

[0030] In summary, compared with existing technologies, it has the following beneficial effects:

[0031] Extend the extension frame 2 outside the quenching furnace, then move the support plate 202 upward so that the fixing block 203 can be inserted into the connecting plate 211. Rotate the threaded rod 207 so that the insertion plate 209 can be inserted into the long slot above the fixing frame 201. Then continue to pull the extension frame 2 to a position that is convenient for placing metal materials. Then move the extension frame 2 back to the entrance position of the quenching furnace body 1. Rotate the threaded rod 207 so that the insertion plate 209 leaves the inside of the fixing frame 201 and move the fixing block 203 away from the inside of the connecting plate 211. Finally, send the extension frame 2 into the position above the support frame 101 inside the quenching furnace body 1. By sending the extension frame 2 out of the quenching furnace body 1, the operating space and space utilization effect above the support frame 101 are increased. When the extension frame 2 is outside the quenching furnace body 1, the support plate 202 and the support plate 205 are used to support the end position of the extension frame 2 outside the quenching furnace body 1, which increases the stability of the extension frame 2 during the movement process and does not affect the normal use of the inside and outside of the quenching furnace body 1.
