Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of heat treatment tooling and equipment, specifically a heat treatment tooling for thin-walled annular aluminum forgings. Background Technology
[0002] Thin-walled annular aluminum forgings refer to precision parts made of aluminum alloy materials through forging processes, which have an annular structure and relatively thin walls. Their core features are the combination of "thin walls" and "annular" structure, as well as the high performance requirements of aluminum alloy materials. They are widely used in fields with high requirements for lightweight, strength and precision.
[0003] Thin-walled annular aluminum forging heat treatment fixtures are special auxiliary tools designed for aluminum annular forgings with thin walls and annular structure characteristics. They are mainly used to ensure the stability of the workpiece in heating, cooling and other process steps, avoid deformation and cracking caused by structural characteristics, and ensure heat treatment uniformity and process consistency.
[0004] In the process of machining thin-walled annular aluminum forgings, the existing heat treatment fixtures for thin-walled annular aluminum forgings generate fine aluminum dust during the machining of aluminum alloys, such as cutting and grinding. However, thin-walled annular parts have high dimensional accuracy requirements. During machining, the accumulation of aluminum chips or dust may jam the tool, scratch the surface of the workpiece, or cause positioning errors in the fixture. Furthermore, dust entering precision components such as machine tool guideways and bearings will accelerate wear and reduce the service life of the equipment. Utility Model Content

The inner wall of the dust collection housing 20 has a dust collection port 23 and an air intake port 24, and the outer wall of the air intake port 24 has a positioning ring 244. The adsorption assembly... The configuration of component 2 allows the grinding roller 10 to process the workpiece while the drive motor rotates the grinding roller 10, which in turn drives the adsorption component 2 to work, adsorbing the floating dust around the workpiece. This reduces the risk of workers being exposed to dusty environments, reduces dust accumulation, lowers the equipment failure rate, and extends the service life of the equipment. The positioning ring 244 is fitted on the outer wall of the air inlet 24 and limits the position of the collection bag, making it easier for workers to replace the collection bag and improving the practicality of the adsorption component 2.
[0039] For details regarding the above embodiments, please refer to [link / reference].

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 The toothed rack 30 is fitted with a first rotating rod 32 at the end away from the drive motor, and a bevel gear set 31 is provided at one end of the first rotating rod 32. The first rotating rod 32 and the second rotating rod 33 are movably connected to the inner wall of the device housing 1, and the inner wall of the device housing 1 effectively supports the first rotating rod 32 and the second rotating rod 33, thereby improving the stability of the bevel gear set 31 when rotating.
[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 , Figure 3 The other end of the bevel gear set 31 is provided with a second rotating rod 33, and the other end of the second rotating rod 33 is provided with an impeller 21. The impeller 21 is driven to rotate by the connecting component 3 to adsorb the floating dust around the workpiece, reducing the risk of workers being exposed to the dusty environment. Secondly, it also reduces dust deposition, lowers the equipment failure rate, and extends the service life of the equipment.
[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The impeller 21 is fitted inside the dust collection housing 20, and a purification screen is provided at the end of the impeller 21 near the air intake 24.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 , Figure 2 and Figure 4 , Figure 5 The top of the air intake 24 is equipped with a movable door 22, which is movably connected to the dust collection housing 20, making it convenient for staff to place and take out the collection bag. The collection bag is made of anti-static nylon cloth bag to reduce the accumulation of dust and the generation of static electricity.

[0045] Second embodiment:
[0046] Please see Figure 5 , Figure 6 The difference between Example 2 and Example 1 is that, while retaining the features of Example 1, a positioning ring 244 and a spring 245 are added to the outer wall of the air inlet 24 to facilitate the replacement of the collection bag and improve the practicality of the adsorption component 2.
[0047] The inner wall of the vacuum cleaner housing 20 is fixedly equipped with an air intake 24, and the outer walls of the air intake 24 are provided with positioning rings 244 at both ends. The two sets of positioning rings 244 are arranged opposite to each other, and a spring 245 is installed between the two sets of positioning rings 244 to effectively limit the position of the positioning rings 244. When the collection bag is placed on the outer wall of the air intake 24, the positioning rings 244 effectively limit the position of the collection bag, making it convenient for the staff to replace the collection bag.
[0048] In practical operation, this utility model is as follows:
[0049] When the device housing 1 processes the workpiece, the workpiece is first placed in the designated position, and then the control button is activated to move the device housing 1 on the track, so that the grinding roller 10 is located on top of the workpiece. When the drive motor drives the grinding roller 10 to rotate and process the workpiece, the drive motor synchronously drives the toothed rack 30 to rotate, which in turn drives the bevel gear set 31 to rotate and thus drives the impeller 21 to rotate. Under the rotation of the impeller 21, the gas and dust around the workpiece flow into the suction port 24 from the dust inlet 23. The outer wall of the suction port 24 is fitted with a collection bag to facilitate the collection of dust and impurities. For the turning and milling of thin-walled ring parts, the dust inlet 23 is set near the tool with a suction force of ≥1500Pa to ensure that aluminum chips are adsorbed as soon as they are generated, reducing diffusion. Secondly, a purification screen is set at one end of the impeller 21. The gas passes through the filter screen and is discharged from the top of the impeller 21, effectively purifying the gas.
[0050] Furthermore, the top of the vacuum cleaner housing 20 is provided with a movable door 22, and the inner wall of the movable door 22 is provided with an air intake 24. The outer wall of the air intake 24 is equipped with a positioning ring 244, and the two ends of the positioning ring 244 are provided with springs 245 to facilitate the positioning of the collection bag.
