Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology, and more specifically, to a heat treatment device with anti-cracking protection. Background Technology

[0002] Heat treatment refers to a metal heat treatment process in which the chemical composition and structure of a metallic material are altered in its solid state through heating, holding, and cooling to obtain desired properties. The heat treatment process mainly includes a heating stage and a cooling stage. In the heating stage, the workpiece is placed in a heat treatment furnace for heating. After heating, the workpiece is removed from the furnace for cooling. One existing cooling method involves placing the workpiece on a support platform and arranging multiple sprayers to spray coolant onto the workpiece surface. However, due to limitations in the number of sprayers, it is often impossible to completely cover all directions around the workpiece, which can lead to uneven coolant spraying and uneven cooling rates on the workpiece surface, potentially causing surface cracking. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a heat treatment device with anti-cracking protection to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a heat treatment device with anti-cracking protection, comprising a base, a heat treatment furnace mounted on the base, a slide rail fixedly mounted on the base, one end of the slide rail corresponding to the outlet direction of the heat treatment furnace, a support platform slidably mounted on the slide rail, a cylindrical ring disposed above the other end of the slide rail, the cylindrical ring being fixedly mounted on a lifting device, the lifting device being fixed on the base, a plurality of radial nozzles being rotatably mounted on the cylindrical ring along the circumference, a plurality of oblique nozzles being fixedly mounted on the outer surface of the radial nozzles inside the cylindrical ring along the circumference, a rotary joint being installed at the end of the radial nozzles outside the cylindrical ring, the rotary joints being connected to a liquid supply device through pipelines, and the radial nozzles being connected to a drive module for transmission, the drive module being used to synchronously drive the multiple radial nozzles to rotate.

[0005] As a preferred technical solution of this utility model, the drive module includes a gear ring, which is coaxially and fixedly connected to a cylindrical ring. The gear ring is driven by a motor, which is fixed on the cylindrical ring. Several magnetic blocks are fixedly fixed around its central axis on the gear ring at intervals. A fixed ring is coaxially and rotatably installed on each radial nozzle outside the cylindrical ring. Several magnets are fixedly installed circumferentially on the outer surface of the fixed ring at intervals, and each magnet attracts a magnetic block.

[0006] In a preferred embodiment of this invention, the number of magnets is not less than four.

[0007] As a preferred embodiment of this utility model, a first sprayer is provided directly above the cylindrical ring, the first sprayer is fixed on the cylindrical ring, and the first sprayer is connected to the liquid supply device through a pipeline.

[0008] As a preferred technical solution of this utility model, a second sprayer is respectively provided on both sides of the slide rail directly below the cylindrical ring. Both second sprayers are fixed on the base and are connected to the liquid supply device through pipelines.

[0009] As a preferred technical solution of this utility model, the surface of the support platform is covered with a grating plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] By incorporating multiple angled nozzles, a first sprayer, and a second sprayer, coolant can be sprayed onto the workpiece from all directions for cooling. Upon activation of the drive module, the motor within the drive module drives multiple radial nozzles to rotate, which in turn rotates the multiple angled nozzles on them. This expands the spray range of each angled nozzle, resulting in a more uniform spray of coolant onto the workpiece surface. This effectively prevents cracking of the workpiece surface due to uneven coolant spraying, thus providing crack protection for the workpiece. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 4 As shown, this utility model provides a heat treatment device with anti-cracking protection, including a base 1, a heat treatment furnace 3 mounted on the base 1, and a slide rail 2 fixedly mounted on the base 1. One end of the slide rail 2 corresponds to the outlet direction of the heat treatment furnace 3. By providing the slide rail 2 and cooperating with the support platform 4, the workpiece can be transferred more conveniently. The support platform 4 is slidably mounted on the slide rail 2. A cylindrical ring 7 is provided above the other end of the slide rail 2. The cylindrical ring 7 is fixedly mounted on a lifting device 6, which is fixed to the base 1. The lifting device 6 is used to drive the cylindrical ring 7 to perform vertical lifting and lowering movements. Several radial nozzles 8 are rotatably mounted on the cylindrical ring 7. Several oblique nozzles 9 are fixedly mounted circumferentially on the outer surface of the radial nozzles 8 inside the cylindrical ring 7. Rotary joints 10 are installed at the ends of the radial nozzles 8 outside the cylindrical ring 7. The rotary joints 10 are all connected to a liquid supply device through pipelines. The radial nozzles 8 are all connected to a drive module for transmission. The drive module is used to synchronously drive multiple radial nozzles 8 to rotate.

[0019] The drive module includes a gear ring 13, which is coaxially and fixedly connected to the cylindrical ring 7. The gear ring 13 is connected to a motor 15, which is fixed on the cylindrical ring 7. Several magnetic blocks 14 are fixedly fixed around the central axis of the gear ring 13 at intervals. A fixed ring 11 is coaxially and rotatably installed on each radial nozzle 8 outside the cylindrical ring 7. Several magnets 12 are fixedly installed circumferentially on the outer surface of the fixed ring 11, and each magnet 12 attracts the magnetic block 14. When in use, the drive module is driven by a motor 15 to rotate the annular gear ring. The annular gear ring drives multiple magnetic blocks 14 to make circular motion. Whenever a magnetic block 14 moves above any fixed ring 11, any magnet 12 on the fixed ring 11 is attracted by the magnetic block 14 and thus receives the force of the magnetic block 14, and moves with the magnetic block 14, so that the fixed ring 11 can rotate. In turn, the fixed ring 11 drives the radial nozzle 8 to rotate. This drive method can greatly simplify the transmission structure, has a low failure rate, and is not easy to cause wear and jamming of the transmission structure due to impurities.

[0020] The number of magnets 12 is not less than four. The four magnets 12 can be more evenly distributed on the fixed ring 11, thereby making the magnetic force transmission between the fixed ring 11 and the magnetic block 14 smoother.

[0021] A first sprayer 16 is installed directly above the cylindrical ring 7. The first sprayer 16 is fixed on the cylindrical ring 7 and is connected to the liquid supply device through a pipeline. The first sprayer 16 is used to spray the upper surface of the workpiece.

[0022] A second sprayer 17 is installed on each side of the slide rail 2 directly below the cylindrical ring 7. Both second sprayers 17 are fixed on the base 1 and are connected to the liquid supply device through pipelines. The second sprayers 17 are used to spray the lower surface of the workpiece.

[0023] The surface of the support platform 4 is covered with a grating plate 5. By covering the grating plate 5, the coolant from the second sprayer 17 can pass through the grating plate 5 to spray the bottom surface of the workpiece.

[0024] In use, the workpiece is placed into the heat treatment furnace 3. After heating, the furnace cover is opened, and the support platform 4 is moved along the slide rail 2 until it approaches the furnace outlet. The workpiece is then moved from the furnace 3 onto the support platform 4 using a tool. The support platform 4 is then moved along the slide rail 2 until it is below the cylindrical ring 7. The lifting device 6 is then controlled to lower the cylindrical ring 7 until it covers the workpiece on the support platform 4. Finally, the liquid supply device is activated, allowing coolant to flow through multiple... The angled nozzles 9, the first sprayer 16, and the second sprayer 17 spray coolant onto the workpiece from all sides to cool it down. After the drive module is activated, the motor 15 in the drive module drives multiple radial nozzles 8 to rotate, which in turn drives multiple angled nozzles 9 to rotate. This expands the spraying range of each angled nozzle 9, resulting in a more uniform spraying of coolant onto the workpiece surface. This effectively avoids the problem of workpiece surface cracking due to uneven coolant spraying, thus achieving crack protection for the workpiece.
