Description

Technical Field

[0001] This utility model relates to the field of magnesium alloy processing technology, specifically to a magnesium alloy heat treatment device that provides uniform heating. Background Technology

[0002] Magnesium alloys are alloys composed of magnesium as a base and other elements added. Heat treatment is a common step in the production process of magnesium alloys. High-quality magnesium alloys require not only the complete isolation of oxygen during heat treatment but also a high degree of temperature uniformity within the heat treatment equipment.

[0003] According to CN218146890U, a magnesium alloy heat treatment device is disclosed. This technology discloses "a magnesium alloy heat treatment device, which relates to the field of magnesium alloy production technology. The magnesium alloy heat treatment device includes a heat treatment chamber with an open top and a top cover covering the opening of the heat treatment chamber. A control chamber is provided at the bottom of the heat treatment chamber. A boss is fixedly connected to the inner bottom wall of the top cover. A connecting groove is provided on the upper surface of the boss. The heat treatment chamber is connected to the control chamber through the connecting groove. A sealing plate matching the shape of the boss is provided inside the connecting groove. A shelf for placing magnesium alloy is fixedly connected to the upper surface of the sealing plate." This technology has the following technical effects: "Activating the telescopic component drives the sealing plate, top cover, and shelf to move vertically upward until the shelf detaches from the heat treatment chamber, thus facilitating unloading. Similarly, placing the magnesium alloy to be heat treated on the shelf allows the sealing plate, top cover, and shelf to enter the interior of the heat treatment chamber under the action of the telescopic component, facilitating loading."

[0004] The magnesium alloy heat treatment device in the above scheme has two main problems: First, the traditional static heating or single rotation method leads to uneven heating of the workpiece, which easily forms a temperature gradient on the magnesium alloy surface, causing abnormal local grain growth or inconsistent microstructure and properties; Second, the fixed loading structure cannot flexibly adjust the capacity, making it difficult to adapt to the processing needs of magnesium alloy workpieces of different sizes and batches, thus limiting production efficiency and equipment versatility. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a magnesium alloy heat treatment device that ensures uniform heating. The device utilizes a combination of rotation of the orbital frame and rotation of the load cell to achieve uniform heating of the magnesium alloy from multiple angles. The modular design allows for rapid expansion of the number of loading layers to adapt to different batch production, thereby improving efficiency, reducing energy consumption, and ensuring stable heat treatment quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a magnesium alloy heat treatment device for uniform heating, comprising a heat treatment chamber, with circumferentially distributed heating elements installed on the inner wall of the heat treatment chamber, and a moving assembly disposed on the heat treatment chamber for controlling the movement of the magnesium alloy, the moving assembly comprising:

A circular plate is fixed on the outer wall of the main shaft and is rotatably mounted inside the sealing cover. A secondary shaft is rotatably mounted through the circular plate. A gear is fixed at the upper end of the secondary shaft and meshes with the gear ring for transmission.

[0008] The assembly includes several mounting rods longitudinally distributed at the lower end of the auxiliary shaft, with loading components mounted on the mounting rods for loading magnesium alloy.

[0009] Preferably, the assembly assembly further includes protrusions fixed on both sides of the upper end of the mounting rod, mounting sleeves are fixed at the bottom of both the mounting rod and the auxiliary shaft, mounting grooves are provided at both ends of the mounting sleeves, a connecting groove is provided at the upper end of the mounting grooves, and a fixing groove is provided at the other end of the connecting grooves.

[0010] Preferably, the loading component includes a fixing sleeve fixed to the outer wall of the mounting rod, and a loading frame is fixed to the outside of the fixing sleeve.

Beneficial effects

[0014] This invention provides a magnesium alloy heat treatment device that ensures uniform heating. Compared with the prior art, it has the following advantages:

[0015] 1. The main shaft is driven by the output end of the motor to rotate the circular plate. When the circular plate rotates, the assembly components are driven to revolve through the secondary shaft. At the same time, with the cooperation of the gear ring, the assembly components on the secondary shaft are driven to rotate by the gear, so that the magnesium alloy is heated from multiple angles during the heat treatment process, ensuring uniform heating of the whole.

[0016] 2. When assembling the components, the mounting rod in the lower assembly component is inserted into the mounting sleeve in the upper assembly component, and the protrusion is inserted from the mounting groove. Then, the mounting rod in the lower assembly component is rotated to drive the protrusion to slide through the connecting groove to the fixing groove. Then, the mounting rod in the lower assembly component is released, and the protrusion on the mounting rod in the lower assembly component is locked into the fixing groove by its own gravity. This realizes the vertical expansion of multi-layer assembly components to adapt to different batch production needs. Attached Figure Description

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.

[0026] Please see Figure 1 - Figure 7 This utility model provides a technical solution: a magnesium alloy heat treatment device for uniform heating, including a heat treatment chamber 1, with circumferentially distributed heating elements 6 installed on the inner wall of the heat treatment chamber 1, and a moving assembly 2 disposed on the heat treatment chamber 1 for controlling the movement of the magnesium alloy, the moving assembly 2 including:

[0027] The drive assembly 21 includes a sealing cover 211 installed at the upper end of the heat treatment chamber 1. A ring seat 212 is fixed inside the upper end of the sealing cover 211. A gear ring 213 is fixed on the inner wall of the ring seat 212. A main shaft 214 is rotatably mounted through the center of the sealing cover 211. A circular plate 215 is fixed on the outer wall of the main shaft 214 and is rotatably mounted inside the sealing cover 211. A secondary shaft 216 is rotatably mounted through the circular plate 215. A gear 217 is fixed at the upper end of the secondary shaft 216 and meshes with the gear ring 213 for transmission.

[0028] Assembly component 22 includes several mounting rods 221 longitudinally distributed at the lower end of the auxiliary shaft 216. Loading components 227 are mounted on the mounting rods 221 and used to load magnesium alloy.

[0029] In this embodiment, when the circular plate 215 rotates, it drives the assembly component 22 to revolve through the secondary shaft 216. At the same time, with the cooperation of the gear ring 213, the assembly component 22 on the secondary shaft 216 rotates through the gear 217, so that the magnesium alloy is heated from multiple angles during the heat treatment process, ensuring uniform heating of the whole.

[0030] Specifically, the assembly component 22 also includes protrusions 222 fixed on both sides of the upper end of the mounting rod 221. The mounting rod 221 and the bottom of the auxiliary shaft rod 216 are both fixed with mounting sleeves 223. Mounting slots 224 are provided at both ends of the mounting sleeves 223. A connecting slot 225 is provided at the upper end of the mounting slot 224. A fixing slot 226 is provided at the other end of the connecting slot 225.

[0031] In this embodiment, when the assembly component 22 is assembled, the mounting rod 221 in the lower assembly component 22 is inserted into the mounting sleeve 223 in the upper assembly component 22, and the protrusion 222 is inserted from the mounting groove 224. Then, the mounting rod 221 in the lower assembly component 22 is rotated to drive the protrusion 222 to slide through the connecting groove 225 to the fixing groove 226. Then, the mounting rod 221 in the lower assembly component 22 is released, and the protrusion 222 on the mounting rod 221 in the lower assembly component 22 is engaged in the fixing groove 226 by its own gravity. This achieves the vertical expansion of the multi-layer assembly component 22 to adapt to different batch production needs.

[0032] Specifically, the loading component 227 includes a fixing sleeve 2271 fixed to the outer wall of the mounting rod 221, and a loading frame 2272 is fixed to the outside of the fixing sleeve 2271.

[0034] Specifically, the drive assembly 21 also includes an inner guide shroud 2110 fixed to the lower end of the main shaft 214, and an outer guide shroud 2111 fixed to the lower end of the sealing cover 211.

[0036] Specifically, the drive assembly 21 also includes a stand 218 fixed to the top of the sealing cover 211. A motor 219 is mounted on the upper end of the stand 218, and the output end of the motor 219 is fixed to the upper end of the main shaft 214.

[0037] In this embodiment, the output end of the motor 219 drives the main shaft 214 to rotate the circular plate 215. Only one motor 219 is needed to control the revolution and rotation of the magnesium alloy.

[0038] Specifically, a base frame 3 is fixed at the rear end of the heat treatment chamber 1, a hydraulic cylinder 4 is installed on the base frame 3, a bracket 5 is slidably installed on the upper end of the base frame 3, and the output end of the hydraulic cylinder 4 is connected to the bracket 5, and the upright frame 218 is fixed inside the upper end of the bracket 5.

[0039] In this embodiment, the output end of the hydraulic cylinder 4 drives the bracket 5 to move the moving component 2 up and down, which facilitates the insertion and removal of the magnesium alloy.

[0040] The working principle and usage process of this utility model are as follows: First, when the assembly component 22 is assembled, the mounting rod 221 in the lower assembly component 22 is inserted into the mounting sleeve 223 in the upper assembly component 22, and the protrusion 222 is inserted from the mounting groove 224. Then, the mounting rod 221 in the lower assembly component 22 is rotated to drive the protrusion 222 to slide through the connecting groove 225 to the fixing groove 226. Then, the mounting rod 221 in the lower assembly component 22 is released, and the protrusion 222 on the mounting rod 221 in the lower assembly component 22 is engaged in the fixing groove 226 by its own gravity, thereby realizing the vertical expansion of the multi-layer assembly component 22 to adapt to different batch production needs.

[0041] Then, the magnesium alloy is placed upright in the loading rack 2272 and arranged in a circle in the loading rack 2272; then the output end of the hydraulic cylinder 4 drives the bracket 5 to drive the moving component 2 to descend into the heat treatment chamber 1, and is heated by the heating element 6;

[0042] Finally, the output end of the motor 219 drives the main shaft 214 to rotate the circular plate 215. When the circular plate 215 rotates, it drives the assembly component 22 to revolve through the secondary shaft 216. At the same time, with the cooperation of the gear ring 213, the assembly component 22 on the secondary shaft 216 rotates through the gear 217, so that the magnesium alloy is heated from multiple angles during the heat treatment process, ensuring uniform heating of the whole.
