Description

Technical Field

[0001] This utility model relates to the field of stainless steel processing technology, specifically to a heat treatment device for improving the properties of precipitation-hardening stainless steel. Background Technology

[0002] Stainless steel is an abbreviation for stainless and acid-resistant steel. It refers to steel that is resistant to weak corrosive media such as air, steam, and water, or that has rust-resistant properties. In its production, stainless steel needs to go through a heat treatment process to obtain mechanical properties such as strength and hardness. A heat treatment furnace is an electric furnace or fuel furnace used to heat the furnace charge for heat treatment. It is suitable for the production of large forgings in industries such as nuclear power, chemical industry, machinery, and boiler. In this process, the workpiece is continuously loaded into the furnace through the feeding door, passes through the furnace chamber, and is continuously discharged from the discharge door.

[0003] Precipitation hardening (or precipitation strengthening) refers to a heat treatment process in which solute atoms in a supersaturated solid solution aggregate in the matrix, leading to hardening. For example, austenitic precipitation-hardening stainless steel, after solution treatment or cold working, can achieve very high strength by undergoing precipitation hardening treatment at 400–500℃ or 700–800℃. In other words, when a supersaturated solid solution of certain alloys is left at room temperature or heated to a certain temperature, solute atoms will aggregate or form a second phase in certain regions of the solid solution lattice, resulting in an increase in the alloy's hardness.

[0004] In existing production processes, stainless steel workpieces are typically heat-treated in a stainless steel heat treatment furnace. However, when removing the workpieces, workers usually need to open the furnace and use tools to remove them one by one. This process is slow, and the furnace is open for a long time, causing heat to dissipate quickly. When the furnace is reused, more energy is needed to reheat it, thus affecting the efficiency of heat treatment. Therefore, we propose a heat treatment device to improve the properties of precipitation hardening stainless steel. Utility Model Content

[0005] The purpose of this invention is to provide a heat treatment device for improving the properties of precipitation-hardening stainless steel, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heat treatment apparatus for improving the properties of precipitation-hardening stainless steel, comprising:

[0008] The heat treatment furnace body has a side groove on one side, a movable frame is slidably installed in the side groove, two movable plates are rotatably installed in the movable frame, two fixed seats are fixedly installed on the top surface of the two movable plates, two fixed columns are fixedly installed on both sides of the inside of the movable frame, and metal hooks are rotatably installed in the four fixed seats, and the multiple metal hooks are respectively movably engaged with the four fixed columns.

[0009] A movable component is disposed on the body of the heat treatment furnace and is used to move the movable frame.

[0010] A storage box is fixedly installed on one side of the heat treatment furnace body. The storage box is located below the movable frame, and a receiving plate is slidably installed inside the storage box.

[0011] A buffer assembly is disposed inside a storage box.

A motor is fixedly installed on one side of the side box, and one end of the motor output shaft is fixedly connected to one end of the lead screw.

[0013] Preferably, the buffer assembly includes two top seats, which are fixedly installed on the bottom surface of the receiving plate. Two movable seats are slidably installed inside the storage box. A first adjusting rod is rotatably installed in one of the movable seats, with its top end rotatably installed in one of the top seats. A rod groove is formed on one side of the first adjusting rod. A second adjusting rod is rotatably installed in the other movable seat, with its top end rotatably installed in the other top seat. The second adjusting rod is slidably connected to the rod groove. Multiple damping rods are fixedly installed on the bottom surface of the storage box, with their top ends fixedly connected to the bottom surface of the receiving plate.

[0014] Preferably, the buffer assembly further includes two inner grooves, which are formed on the inner bottom surface of the storage box.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This heat treatment equipment for improving the properties of precipitation-hardening stainless steel involves placing the stainless steel workpiece to be heat-treated into a moving frame. The moving component moves the moving frame into the heat treatment furnace body, where the furnace body heat-treats the stainless steel in the moving frame. After the stainless steel is treated, a motor is started to drive the lead screw to rotate. As the lead screw rotates, a slider moves the threaded sleeve, which in turn moves the moving frame. At this point, the moving frame is removed from the heat treatment furnace body, making it easier to remove the stainless steel from the moving frame.

[0020] 2. This heat treatment equipment for improving the properties of precipitation-hardening stainless steel allows the metal hooks to be pulled upwards after heat treatment of the stainless steel within the moving frame. Once the metal hooks detach from the fixed column, the limiting effect on the movable plates is released, and the stainless steel workpieces on the two movable plates will automatically fall into the storage box. When the stainless steel workpieces fall into the storage box, they will contact the receiving plate. The cooperation of the first adjusting rod, the moving seat, the top seat, the second adjusting rod, the rod groove, the inner groove, the moving block, the buffer spring, and the damping rod will have a buffering effect, preventing the stainless steel workpieces from falling directly and causing damage.

[0030] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0031] A heat treatment device for improving the properties of precipitation-hardening stainless steel includes: a heat treatment furnace body 1, a side groove 2 on one side of the heat treatment furnace body 1, a movable frame 3 slidably installed in the side groove 2, two movable plates 4 rotatably installed in the movable frame 3, two fixed seats 8 fixedly installed on the top surface of each of the two movable plates 4, two fixed columns 6 fixedly installed on both sides of the interior of the movable frame 3, and metal hooks 10 rotatably installed in each of the four fixed seats 8, with the multiple metal hooks 10 respectively movably engaged with the four fixed columns 6; a moving assembly, which is disposed on the heat treatment furnace body 1 and is used to move the movable frame 3; a storage box 12, which is fixedly installed on one side of the heat treatment furnace body 1, located below the movable frame 3, and a receiving plate 19 slidably installed in the storage box 12; and a buffer assembly, which is disposed in the storage box 12. When the stainless steel workpiece to be heat-treated is placed into the movable frame 3, the moving assembly moves the movable frame 3 into the heat treatment furnace body 1, whereby the heat treatment furnace body 1 heat-treats the stainless steel in the movable frame 3.

[0032] In this embodiment, the moving component includes a side box 15, which is fixedly installed on one side of the heat treatment furnace body 1. A lead screw 16 is rotatably installed inside the side box 15, and a threaded sleeve 9 is threadedly connected to the lead screw 16. A slider 17 is slidably installed inside the heat treatment furnace body 1. One end of the slider 17 is fixedly connected to one side of the moving frame 3, and the other end of the slider 17 is fixedly connected to one side of the threaded sleeve 9. A motor 18 is fixedly installed on one side of the side box 15, and one end of the output shaft of the motor 18 is fixedly connected to one end of the lead screw 16. After the stainless steel is treated, the motor 18 is started to drive the lead screw 16 to rotate. When the lead screw 16 rotates, the threaded sleeve 9 will move through the slider 17. When the threaded sleeve 9 moves, the moving frame 3 will move through the slider 17. At this time, the moving frame 3 will move out of the heat treatment furnace body 1, thereby facilitating the removal of the stainless steel inside the moving frame 3.

[0033] In this embodiment, the buffer assembly includes two top seats 21, which are fixedly installed on the bottom surface of the receiving plate 19. Two movable seats 20 are slidably installed inside the storage box 12. A first adjusting rod 11 is rotatably installed inside one of the movable seats 20, and the top end of the first adjusting rod 11 is rotatably installed inside one of the top seats 21. A rod groove 23 is opened on one side of the first adjusting rod 11. A second adjusting rod 22 is rotatably installed inside the other movable seat 20, and the top end of the second adjusting rod 22 is rotatably installed inside the other top seat 21. The second adjusting rod 22 is slidably connected to the rod groove 23. A plurality of damping rods 7 are fixedly installed on the bottom surface of the storage box 12, and the top ends of the plurality of damping rods 7 are fixedly connected to the bottom surface of the receiving plate 19.

[0034] In this embodiment, the buffer assembly also includes two inner grooves 24, which are formed on the inner bottom surface of the storage box 12. Each inner groove 24 has a movable block 25 slidably installed inside it. The top of each movable block 25 is fixedly connected to the bottom surface of each movable seat 20. Each inner side of each inner groove 24 has a buffer spring 26 fixedly installed inside it. One end of each buffer spring 26 is fixedly connected to one side of each movable block 25. When the receiving plate 19 moves, the two movable seats 20 will move due to the cooperation of the top seat 21, the rod groove 23, the second adjusting rod 22 and the first adjusting rod 11. When the movable seats 20 move, they will move the movable blocks 25. When the movable blocks 25 move, the buffer spring 26 and the damping rod 7 will have a buffering effect.

[0035] In this embodiment, a sealing cover plate 5 is fixedly installed on one side of the movable frame 3. The sealing cover plate 5 is sleeved with the side groove 2. A sealing strip is provided on the outer side wall of the sealing cover plate 5. When the movable frame 3 moves into the heat treatment furnace body 1, the sealing cover plate 5 will be sleeved with the side groove 2 to keep the heat treatment furnace body 1 sealed and prevent the heat inside the heat treatment furnace body 1 from being lost.

[0036] In this embodiment, two support rods 13 are fixedly installed on the bottom surface of the sealing cover plate 5. The bottom ends of the two support rods 13 are fixedly installed with casters 14.

[0037] In this embodiment, the distance between the two support rods 13 is greater than the width of the storage box 12. When the sealing cover 5 is in contact with the side groove 2, the storage box 12 will not block the support rods 13 because the distance between the two support rods 13 is greater than the width of the storage box 12.

[0038] In this embodiment, the heat treatment equipment for improving the properties of precipitation-hardening stainless steel is used by placing the stainless steel workpiece to be heat-treated into the moving frame 3. The moving component moves the moving frame 3 into the heat treatment furnace body 1. The heat treatment furnace body 1 heat-treats the stainless steel in the moving frame 3. After the stainless steel is treated, the motor 18 is started to drive the lead screw 16 to rotate. When the lead screw 16 rotates, it drives the threaded sleeve 9 to move through the slider 17. When the threaded sleeve 9 moves, it drives the moving frame 3 to move through the slider 17. At this time, the moving frame 3 will be moved out of the heat treatment furnace body 1, which makes it convenient to take out the stainless steel in the moving frame 3.

[0039] After the stainless steel is heat-treated in the movable frame 3, the metal hook 10 can be pulled upwards. When the metal hook 10 is disengaged from the fixed column 6, the restriction on the movable plate 4 is released. At this time, the stainless steel workpieces on the two movable plates 4 will automatically fall into the storage box 12. When the stainless steel workpieces fall into the storage box 12, they will contact the receiving plate 19. The cooperation of the first adjusting rod 11, the movable seat 20, the top seat 21, the second adjusting rod 22, the rod groove 23, the inner groove 24, the movable block 25, the buffer spring 26, and the damping rod 7 will have a buffering effect, preventing the stainless steel workpieces from falling directly and being damaged. This method can quickly unload the material. After unloading, new stainless steel workpieces can be placed in the movable frame 3 for heat treatment, which improves production efficiency.
