The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0020] First embodiment

[0021] See also Figures 1 to 3 , Figure 1 This is a structural diagram of a fixing frame for heat treatment of metal parts according to the first embodiment of the utility model. Figure 2 This is a front view of a fixing frame for heat treatment of metal parts according to the first embodiment of the utility model. Figure 3 It is a cross-sectional schematic diagram of a fixing frame for heat treatment of metal parts according to the first embodiment of the utility model.

[0022] The present utility model provides a fixing rack for heat treatment of metal components: including a placement plate 101 and a lifting assembly 102. The lifting assembly 102 includes a connecting frame 103, an installation groove 104, an installation frame 105, a horizontal plate 106, a handle 107, a sleeve 108, a gear set 109, a lead screw 110, a first gear 111, a second gear 112, a roller 113, a pull handle 114, a box body 115 and a moving wheel 116. Through the foregoing solution, the problem that in the use of the existing device, after heat treatment, the parts need to be cooled, but the surface temperature of the parts is high, making it difficult to quickly process them, resulting in low production efficiency, is solved.

[0023] In this embodiment, the placement plate 101 is used to place the parts to be processed.

[0024] Among them, the connecting frame 103 is fixedly connected to the placement plate 101 and is located on one side of the placement plate 101. The installation frame 105 is slidably connected to the connecting frame 103 and is located on one side of the connecting frame 103. The horizontal plate 106 is fixedly installed on the connecting frame 103. The installation groove 104 is fixedly connected to the installation frame 105 and is located on one side of the installation frame 105. The gear set 109 is arranged inside the installation groove 104. The sleeve 108 is connected to the gear set 109 and is rotatably connected to the installation groove 104 and is located on one side of the installation groove 104. The lead screw 110 is connected to the gear set 109 and is rotatably connected to the installation frame 105 and is located on one side of the installation frame 105. The handle 107 is slidably connected to the sleeve 108 and is located on one side of the sleeve 108. The horizontal plate 106 is threadedly connected to the lead screw 110 and is located on one side of the lead screw 110. Place the installation frame 105 inside the heat treatment heating box. After heating is completed, place a device for storing a cooling medium at the bottom of the placement plate 101. Then slide the handle 107 into the sleeve 108. Rotate the gear set 109 through the handle 107 to drive the lead screw 110 to rotate, so that the placement plate 101 is lifted and lowered. Not only can the handle 107 be removed during lifting and lowering to prevent the temperature of the handle 107 from rising during the heat treatment process, but also the parts on the placement plate 101 can sink into the cooling medium. This application can quickly transition the heat-treated parts to the cooling process, solving the problem that in the use of the existing device, after heat treatment, the parts need to be cooled, but the surface temperature of the parts is high, making it difficult to quickly process them, resulting in low production efficiency.

[0025] Secondly, the gear set 109 includes a first gear 111 and a second gear 112. Both the first gear 111 and the second gear 112 are rotatably installed inside the installation groove 104 and are meshed with each other. The sleeve 108 is fixedly connected to the first gear 111 and is located on one side of the first gear 111. The lead screw 110 is fixedly connected to the second gear 112 and is located on one side of the second gear 112. After the handle 107 is inserted into the sleeve 108, by rotating the handle 107, the first gear 111 is rotated. Since the first gear 111 is meshed with the second gear 112, the lead screw 110 on the second gear 112 is driven to rotate. The outer circle and inner square of the sleeve 108 prevent the handle 107 from rotating inside the sleeve 108 after being inserted.

[0026] Thirdly, the lifting assembly 102 further includes a roller 113 and a handle 114. The handle 114 is fixedly connected to the mounting bracket 105 and is located on one side of the mounting bracket 105. The roller 113 is rotatably connected to the mounting bracket 105 and is located at the bottom of the mounting bracket 105. The roller 113 reduces the friction between the device and the placement surface, facilitating the movement of the device. By the handle 107 through the force point, it is convenient to push and pull the device when moving the device.

[0027] Finally, the lifting assembly 102 further includes a box body 115 and moving wheels 116. The box body 115 is arranged at the bottom of the placement plate 101. The moving wheels 116 are rotatably connected to the box body 115 and are located at the bottom of the box body 115. The box body 115 can hold the medium for cooling. The moving wheels 116 are used to transfer the position of the box body 115 so that the box body 115 can be quickly placed at the bottom of the placement plate 101.

[0028] When using a fixing rack for heat treatment of metal parts of the present utility model, the placement plate 101 is used to place the parts to be processed. The mounting bracket 105 is placed inside the heat treatment heating box. After heating is completed, a device for storing the cooling medium is placed at the bottom of the placement plate 101. Then, the handle 107 is slid into the sleeve 108, and the gear set 109 is rotated by the handle 107 to drive the lead screw 110 to rotate, so that the placement plate 101 is lifted and lowered. During the lifting and lowering, the handle 107 can be removed, preventing the temperature of the handle 107 from rising during the heat treatment process and causing the parts on the placement plate 101 to sink into the cooling medium. This application can quickly transition the heat-treated parts to the cooling process, solving the problem that in the existing device during use, after heat treatment, the parts need to be cooled, but the surface temperature of the parts is high and it is difficult to quickly process them, resulting in low production efficiency.

[0029] Second Embodiment

[0030] Please refer to Figure 4 , Figure 4 which is a schematic cross-sectional view of a fixing rack for heat treatment of a metal component according to the second embodiment of the present utility model. On the basis of the first embodiment, the lifting assembly 102 of the fixing rack for heat treatment of a metal component of the present utility model further includes a support frame 201, a threaded rod 202, and a clamping plate 203.

[0031] The support frame 201 is fixedly connected to the placing plate 101 and is located on one side of the placing plate 101. The threaded rod 202 is threadedly connected to the support frame 201 and is located on one side of the support frame 201. The clamping plate 203 is rotatably connected to the threaded rod 202, slidably connected to the support frame 201, and is located on one side of the support frame 201. By rotating the threaded rod 202, the clamping plate 203 is controlled to move along with the threaded rotation direction of the threaded rod 202. The clamping plate 203 restricts the position of the part between the placing plate 101 and the clamping plate 203. Both the clamping plate 203 and the placing plate 101 are made of a hollow high-temperature resistant mesh plate.
