[0002] Heat treatment is a process that changes the physical and chemical properties of a material by heating and cooling it. This is often used to improve a material's hardness, strength, corrosion resistance, and other properties. Heat treatment can be applied to a variety of materials, including metals and alloys, ceramics, and plastics.

[0003] The utility model with the publication number of CN215481059U discloses an anti-deformation fixing fixture for heat treatment of cold-working die steel, including a fixing seat, a first clamping mechanism and a second clamping mechanism, wherein the first clamping mechanism is arranged on one side of the top of the fixing seat, and the second clamping mechanism is arranged on one side of the top of the fixing seat, and the first clamping mechanism includes a first clamping component, a first pull rod, a first spring and a first gasket, one end of the two first pull rods are respectively fixedly connected and fixed to the two ends of one side of the first clamping component, the middle part of the first gasket is movably sleeved with one end of the first pull rod, and one end of the first spring is fixedly connected to one side of the first gasket. The utility model uses a setting mode in which the first clamping mechanism and the second clamping mechanism are matched, and during the heat treatment process of the cold-working die steel, the first clamping component in the first clamping mechanism cooperates with the fixing seat to clamp the two sides of the cold-working die steel, and the deformation of the first spring is used to realize the anti-deformation of the two sides of the cold-working die steel.

[0004] In the prior art, workers generally place materials that need to be heat treated on a workbench and move them to a heat treatment furnace to heat the items. After heating, the materials are cooled by natural cooling, water cooling, oil cooling, etc., thereby achieving heat treatment of the materials. However, in the prior art, in most cases, when limiting the materials on the workbench, the pull rod limiting method used can clamp and limit the materials. However, after long-term use, the limiting effect of the pull rod will reduce the clamping effect due to wear, thereby failing to effectively and firmly fix the materials. Now, a fixing clamp for heat treatment is proposed. Utility Model Content

[0036] The following is combined with Figure 1-6 This application is described in further detail.

[0037] Please refer to Figure 1-6 A fixing fixture for heat treatment includes a workbench 1. A transverse clamping mechanism 2 and a longitudinal clamping mechanism 3 are arranged on the upper side of the workbench 1. The transverse clamping mechanism 2 can limit and restrict the material placed on the upper side of the workbench 1, thereby increasing the stability of the material when it is limited, and the longitudinal clamping mechanism 3 can cooperate with the transverse clamping mechanism 2 to further effectively limit the side of the material that is not limited, thereby increasing the stability of the material when it is heated.

[0038] The transverse clamping mechanism 2 includes a fixed block 21, a bidirectional screw 22, a threaded block 23, a rotating rod 24 and a movable block 25, and two threaded blocks 23 and two rotating rods 24 are provided. The fixed block 21 is fixedly connected to the upper side of the workbench 1, and the bidirectional screw 22 is rotatably connected to one side of the fixed block 21. The two threaded blocks 23 are both threadedly connected to the outer side of the bidirectional screw 22, and the two threaded blocks 23 are both slidably connected to the upper side of the workbench 1. The workbench 1 can install and fix the bidirectional screw 22 through the fixed block 21, so that the bidirectional screw 22 can rotate smoothly, and the bidirectional screw 22 can be connected to the threaded block 23, and the threads on both sides of the threaded block 23 are opposite.

[0039] See also Figure 1 and Figure 2 The rotating rod 24 is rotatably connected to one side of the threaded block 23, and the moving block 25 is rotatably connected to one side of the rotating rod 24. The workbench 1 can limit the threaded block 23 to a certain extent, so that the threaded block 23 can slide smoothly on the upper side of the workbench 1, and the threaded block 23 can be connected to the moving block 25 through the rotating rod 24. At the same time, the bidirectional screw 22 can drive the two threaded blocks 23 to move in opposite directions when rotating through the opposite threads on both sides of itself and the limiting of the threaded block 23 by the workbench 1. When moving, the threaded block 23 can push or pull the moving block 25 through the rotating rod 24, thereby realizing the movement of the moving block 25. After the moving block 25 moves to a certain distance, the material can be clamped and limited.

[0040] Reference Figure 1 and Figure 2 The longitudinal clamping mechanism 3 includes a connecting plate 31, a first tension spring 32 and a first limiting plate 33. Two connecting plates 31 are provided and are respectively located on both sides of the upper surface of the workbench 1. The first tension spring 32 is fixedly connected to the inner side of the connecting plate 31, and the first limiting plate 33 is fixedly connected to one end of the first tension spring 32. More specifically, the connecting plate 31 can install and fix the first limiting plate 33 through the first tension spring 32, and the first limiting plate 33 can further limit the material on the upper side of the workbench 1. At the same time, since the material may expand thermally when being heated, the first tension spring 32 can use its own elasticity to limit the material on the first limiting plate 33 while enabling the first limiting plate 33 to have a certain movement effect, so that the first limiting plate 33 is not easy to squeeze the thermal expansion of the material when limiting the material.

[0041] Reference Figure 2 and Figure 5 A mounting plate 4 is provided on one side of the threaded block 23 , and a mounting assembly 5 is provided between the mounting plate 4 and the connecting plate 31 .

[0042] The mounting assembly 5 includes a clamping block 51, which is fixedly connected to one side of the connecting plate 31. A clamping groove 52 is provided on one side of the mounting plate 4, and the clamping block 51 is movably clamped in the inside of the clamping groove 52. More specifically, the mounting assembly 5 can connect the connecting plate 31 and the mounting plate 4, so that the connecting plate 31 can be smoothly and conveniently installed on one side of the mounting plate 4 when needed. The connecting plate 31 can install and fix the clamping block 51. After the clamping block 51 is clamped to the inside of the clamping groove 52, the mounting plate 4 can connect the connecting plate 31 through the connection relationship between the clamping block 51 and the clamping groove 52. At the same time, after the connecting plate 31 is connected to the mounting plate 4, the connecting plate 31 can move following the threaded block 23.

[0043] Reference Figure 2 and Figure 5 A hollow groove 6 is provided on one side of the mounting plate 4, and the hollow groove 6 is provided with a plurality of them, and the plurality of hollow grooves 6 are the same size as the card slot 52, and the plurality of hollow grooves 6 are adapted to the card block 51. More specifically, the opening of the hollow groove 6 and the plurality of settings of the hollow groove 6 allow the staff to adjust the position of the connecting plate 31 according to the size of the material. When the position of the connecting plate 31 needs to be adjusted, it is only necessary to card the card block 51 into the inside of the hollow groove 6 at the corresponding position, so that the position of the connecting plate 31 can be adjusted simply and conveniently when it needs to.

[0044] Reference Figure 2 and Figure 3An auxiliary component 7 is provided on one side of the moving block 25, and the auxiliary component 7 includes a second tension spring 71 and a second limiting plate 72. The second tension spring 71 is fixedly connected to one side of the moving block 25, and the second limiting plate 72 is fixedly connected to one end of the second tension spring 71. More specifically, the auxiliary component 7 has a similar function to the first tension spring 32, and can reduce the hindering effect of the moving block 25 on the thermal expansion of the material when the material expands thermally while the moving block 25 limits and clamps the material. The moving block 25 can install and fix the second limiting plate 72 through the second tension spring 71, and the second limiting plate 72 can cooperate with the moving block 25 to clamp and limit the material. The second tension spring 71 can use its own elasticity to enable the second limiting plate 72 to move a short distance according to the thermal expansion of the material.

[0045] Reference Figure 2 and Figure 3 A slide bar 9 is fixedly connected to one side of the second limit plate 72, a slide groove 8 is opened on one side of the moving block 25, the slide bar 9 is slidably connected to the inside of the slide groove 8, and the moving block 25 is arranged on the outside of the slide bar 9. More specifically, the second limit plate 72 can install and fix the slide bar 9, and the moving block 25 can limit the slide bar 9 through the slide groove 8. This makes it possible for the second limit plate 72 to move due to the thermal expansion of the material, and the contraction of the second tension spring 71 and the movement of the second limit plate 72 can be sufficiently stable and not prone to displacement.

[0046] Reference Figure 4 and Figure 6 A limiting groove 10 is provided on the upper side of the workbench 1, and a limiting block 11 is fixedly connected to the lower side of the threaded block 23. The limiting block 11 is slidably connected to the inside of the limiting groove 10. More specifically, the threaded block 23 can be connected to the limiting block 11, and the workbench 1 can limit the limiting block 11 through the limiting groove 10. Since the limiting block 11 and the threaded block 23 are fixedly connected, the threaded block 23 will be restricted by the limiting groove 10 when moving, thereby increasing the stability of the threaded block 23 when moving.

[0047] Reference Figure 4 and Figure 6The workbench 1 is located inside the limit groove 10 and is fixedly connected to the limit rod 12. The limit block 11 is slidably connected to the outside of the limit rod 12. One end of the bidirectional screw 22 is fixedly connected to the extension rod 13, and one end of the extension rod 13 passes through the fixed block 21. The fixed block 21 and the extension rod 13 are rotatably connected. More specifically, the limit rod 12 can limit the limit block 11, so that the limit block 11 has good stability while limiting the threaded block 23 through the connection relationship between itself and the limit groove 10. At the same time, the setting of the extension rod 13 can facilitate the staff to rotate the bidirectional screw 22, thereby increasing the simplicity and convenience of the bidirectional screw 22 when it needs to be rotated.

[0048] The implementation principle of the utility model is as follows: when the device is in use, the staff can place the material on the upper side of the workbench 1, and after placing it, install the connecting plate 31 to one side of the mounting plate 4. When installing the connecting plate 31, the staff can insert the card block 51 into the card slot 52 or the hollow slot 6 at different positions according to the size of the material, and then the staff can rotate the extension rod 13. When the extension rod 13 rotates, it will drive the bidirectional screw 22 to rotate. When the bidirectional screw 22 rotates, it can smoothly pass through the opposite of the threads on both sides of itself and the limit of the thread block 23 of the workbench 1, and drive the two thread blocks 23 to move in opposite directions when rotating. When the thread block 23 moves, it can push or pull the moving block 25 through the rotating rod 24. When the moving block 25 moves, it will drive the second limiting plate 72 to move together. After the second limiting plate 72 moves to a certain distance, it will be clamped on the outside of the material. At the same time, the mounting plate 4 will also move with the thread block 23, and drive the connecting plate 31 to slide together when moving.

[0049] In addition, when the connecting plate 31 stops moving, the first limiting plate 33 will also clamp the material, thereby achieving the limitation and fixation of the material. This can solve the problem that after long-term use, the limiting effect of the pull rod will reduce the clamping effect due to wear, thereby failing to effectively and firmly fix the material.

[0050] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
