Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy casting processing technology, specifically to a heat treatment device for cast aluminum alloy castings. Background Art

[0002] Aluminum alloy castings refer to equipment and components made of pure aluminum or aluminum alloys using casting processes. Generally, aluminum or aluminum alloy heated to a liquid state is poured into the mold cavity using a sand mold or metal mold to obtain aluminum or aluminum alloy parts of various shapes and sizes, which are commonly referred to as aluminum alloy castings.

[0003] However, existing heat treatment equipment for cast aluminum alloy castings requires workers to manually place the aluminum alloy castings into the heat treatment furnace and manually remove them after heat treatment. However, the surface of the heat-treated aluminum alloy castings retains a high temperature, which can easily cause injury to workers. In addition, the heat-treated aluminum alloy castings need to be manually moved to a designated position, which is a cumbersome operation and has a certain impact on the heat treatment efficiency of aluminum alloy castings. Therefore, a heat treatment device for cast aluminum alloy castings is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a heat treatment device for cast aluminum alloy castings. This invention solves the problem of low heat treatment efficiency of aluminum alloy castings in existing heat treatment devices by setting up a drive assembly, a placement rack, a cylinder, a cover, and a transmission rack.

[0005] The technical solution adopted by this utility model to solve its technical problem is a heat treatment device for casting aluminum alloy castings, including a heat treatment furnace. A cylinder for providing power is bolted to the outside of the heat treatment furnace. A transmission frame is bolted to the power output end of the cylinder, and a cover is welded to one side of the transmission frame. A placement frame for placing aluminum alloy castings is bolted to one side of the cover. A drive assembly for removing the heat-treated aluminum alloy castings is provided at the bottom of the placement frame. The drive assembly includes a servo motor, a threaded rod, a threaded sleeve, a drive frame, and a fixing plate. The servo motor for providing power is bolted to the bottom of the placement frame, and a threaded rod is keyed to the power output end of the servo motor. A threaded sleeve is threaded to the outside of the threaded rod, and a drive frame is welded to the outside of the threaded sleeve. A fixing plate for removing the heat-treated aluminum alloy castings is welded to one side of the drive frame. A base for supporting the heat treatment furnace is bolted to the bottom of the heat treatment furnace, and a box for collecting the heat-treated aluminum alloy castings is bolted to one side of the base.

[0006] By adopting the above technical solution, when heat-treating aluminum alloy castings, the aluminum alloy castings are first placed in the placement rack. Then, the cylinder outside the heat treatment furnace is driven by an external controller to move the transmission frame. The transmission frame then moves the cover, and the cover then carries the aluminum alloy castings on the placement rack into the heat treatment furnace. The heat treatment furnace then performs heat treatment on the aluminum alloy castings. After the heat treatment is completed, the cylinder drives the cover on the transmission frame to move, and the cover then moves the placement rack out of the heat treatment furnace. Then, the servo motor at the bottom of the placement rack is controlled by an external controller to convert the received electrical energy into mechanical energy. The servo motor drives the threaded rod to rotate, and the threaded sleeve outside the threaded rod moves laterally outside the threaded rod under the action of an external limiting structure. Then, the drive frame outside the threaded sleeve drives the fixed plate to move, so that the fixed plate moves out of the placement rack. Then, the aluminum alloy castings in the placement rack enter the box on the base, which facilitates the collection and processing of the heat-treated aluminum alloy castings and improves the heat treatment efficiency of aluminum alloy castings.

[0007] Specifically, a fixed rod is slidably connected to the inner side of the transmission frame, and limit blocks are symmetrically welded to the outside of the transmission frame. Limiting grooves that allow the limit blocks to slide are symmetrically opened on the surface of the heat treatment furnace.

[0008] By adopting the above technical solution, when the cylinder drives the transmission frame to move, the limiting block outside the transmission frame slides in the limiting groove opened on the heat treatment furnace, while the transmission frame slides outside the fixed rod, thereby improving the stability of the transmission frame movement.

[0009] Specifically, the inner side of the cover is screwed with a rubber gasket to increase the sealing between the cover and the heat treatment furnace.

[0010] By adopting the above technical solution, when the cover is moved to the outside of the heat treatment furnace, the rubber gasket inside the cover comes into contact with the surface of the heat treatment furnace, thereby improving the sealing between the cover and the heat treatment furnace.

[0011] Specifically, a support rod is welded to one side of the placement frame, and a fixed sleeve connected to the drive frame is slidably connected to the outside of the support rod. Sliding grooves are symmetrically opened on the inner side of the placement frame, and a connecting block connected to the fixed plate is slidably connected to the inner side of the sliding groove.

[0012] By adopting the above technical solution, when the drive frame moves the fixed plate, the fixed sleeve outside the drive frame slides outside the support rod, and at the same time the connecting block outside the fixed plate slides in the groove opened in the placement frame, thereby improving the stability of the drive frame moving the fixed plate.

[0013] Specifically, the input terminals of both the cylinder and the servo motor are electrically connected to the power supply terminal of an external power source.

[0014] By adopting the above technical solution and connecting to an external power source, the electrical equipment can operate normally.

[0015] The beneficial effects of this utility model are:

[0016] The present invention discloses a heat treatment device for aluminum alloy castings. When heat treatment is required, the aluminum alloy casting is first placed in a placement rack. Then, a cylinder outside the heat treatment furnace, driven by an external controller, moves a transmission frame. The transmission frame then moves a cover, which in turn moves the aluminum alloy casting from the placement rack into the heat treatment furnace. The furnace then performs heat treatment on the aluminum alloy casting. After heat treatment, the cylinder moves the cover on the transmission frame, which in turn moves the placement rack out of the furnace. A servo motor at the bottom of the placement rack, driven by an external controller, converts received electrical energy into mechanical energy. The servo motor drives a threaded rod to rotate. A threaded sleeve outside the threaded rod moves laterally outside the rod under the action of an external limiting structure. A drive frame outside the threaded sleeve moves a fixing plate, causing the fixing plate to move out of the placement rack. The aluminum alloy casting then enters a box on the base, facilitating the collection and processing of the heat-treated aluminum alloy casting and improving the heat treatment efficiency.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] To improve the heat treatment efficiency of aluminum alloy castings, as one embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 3As shown, the present invention discloses a heat treatment device for casting aluminum alloy parts, comprising a heat treatment furnace 2. A cylinder 3, providing power, is bolted to the outside of the heat treatment furnace 2. A transmission frame 20 is bolted to the power output end of the cylinder 3, and a cover 9 is welded to one side of the transmission frame 20. A placement frame 8 for placing aluminum alloy castings is bolted to one side of the cover 9. A drive assembly 19 for removing the heat-treated aluminum alloy castings is provided at the bottom of the placement frame 8. The drive assembly 19 includes a servo motor 11, a threaded rod 16, a threaded sleeve 15, and a drive mechanism. The frame 21 and the fixing plate 4 are provided. The bottom of the placement frame 8 is bolted to a servo motor 11 that provides power. The power output end of the servo motor 11 is keyed to a threaded rod 16. The threaded rod 16 is externally threaded to a threaded sleeve 15. A drive frame 21 is welded to the outside of the threaded sleeve 15. A fixing plate 4 is welded to one side of the drive frame 21 to remove the heat-treated aluminum alloy casting. The bottom of the heat treatment furnace 2 is bolted to a base 7 that supports the heat treatment furnace 2. A box 10 for collecting the heat-treated aluminum alloy casting is bolted to one side of the base 7.

[0024] In operation, when heat treating aluminum alloy castings, the castings are first placed in the placement rack 8. Then, the cylinder 3 outside the heat treatment furnace 2, controlled by an external controller, moves the transmission frame 20. The transmission frame 20 then moves the cover 9, which in turn moves the aluminum alloy casting on the placement rack 8 into the heat treatment furnace 2. The furnace then performs the heat treatment on the castings. After the heat treatment is complete, the cylinder 3 moves the cover 9 on the transmission frame 20, and the cover 9 moves the placement rack 8 out of the furnace 2. The servo motor 11 at the bottom of the placement rack 8 converts the received electrical energy into mechanical energy under the action of an external controller. The servo motor 11 drives the threaded rod 16 to rotate. The threaded sleeve 15 outside the threaded rod 16 moves laterally outside the threaded rod 16 under the action of an external limiting structure. Then, the drive frame 21 outside the threaded sleeve 15 drives the fixed plate 4 to move, so that the fixed plate 4 is removed from the placement rack 8. Then, the aluminum alloy castings in the placement rack 8 enter the box 10 on the base 7, which facilitates the collection and processing of the heat-treated aluminum alloy castings and improves the heat treatment efficiency of the aluminum alloy castings.

[0025] To improve the stability of the drive frame 21 moving the fixed plate 4, for example, such as Figure 2 As shown, the present invention also includes a fixed rod 1 slidably connected to the inner side of the transmission frame 20, a limiting block 6 symmetrically welded to the outside of the transmission frame 20, and a limiting groove 5 symmetrically opened on the surface of the heat treatment furnace 2 to allow the limiting block 6 to slide.

[0026] When in use, when the cylinder 3 drives the transmission frame 20 to move, the limiting block 6 outside the transmission frame 20 slides in the limiting groove 5 opened on the heat treatment furnace 2, and at the same time the transmission frame 20 slides outside the fixed rod 1, thereby improving the stability of the movement of the transmission frame 20.

[0027] To improve the sealing between the cover 9 and the heat treatment furnace 2, for example, such as Figure 3 As shown, this utility model also includes a rubber gasket 18 that is screwed on the inner side of the cover 9 to increase the sealing between the cover 9 and the heat treatment furnace 2.

[0028] When in use, when the cover 9 is moved to the outside of the heat treatment furnace 2, the rubber gasket 18 inside the cover 9 comes into contact with the surface of the heat treatment furnace 2, thereby improving the sealing between the cover 9 and the heat treatment furnace 2.

[0029] To improve the stability of the drive frame 21 moving the fixed plate 4, for example, such as Figure 1 , Figure 2 and Figure 3 As shown, the present invention also includes a support rod 12 welded to one side of the placement frame 8, and a fixed sleeve 17 connected to the drive frame 21 is slidably connected to the outside of the support rod 12. The placement frame 8 has symmetrically opened sliding grooves 14 on the inner side, and a connecting block 13 connected to the fixed plate 4 is slidably connected to the inner side of the sliding grooves 14.

[0030] When in use, when the drive frame 21 moves the fixed plate 4, the fixed sleeve 17 outside the drive frame 21 slides outside the support rod 12, and at the same time the connecting block 13 outside the fixed plate 4 slides in the groove 14 opened in the placement frame 8, thereby improving the stability of the drive frame 21 moving the fixed plate 4.

[0031] For electrical equipment to function properly, for example, such as Figure 1 , Figure 2 and Figure 3 As shown, the present invention also includes that the input terminals of the cylinder 3 and the servo motor 11 are electrically connected to the power supply terminal of an external power source.

[0032] When in use, the electrical equipment works normally by connecting to an external power source.

[0033] In use, when heat treating aluminum alloy castings, the aluminum alloy castings are first placed in the placement rack 8. Then, the cylinder 3 outside the heat treatment furnace 2, driven by an external controller, moves the transmission rack 20. The transmission rack 20 then moves the cover 9, which in turn moves the aluminum alloy casting on the placement rack 8 into the heat treatment furnace 2. The heat treatment furnace 2 then performs the heat treatment on the aluminum alloy casting. After the heat treatment is completed, the cylinder 3 moves the cover 9 on the transmission rack 20, and the cover 9 then moves the placement rack 8 out of the heat treatment furnace 2. Then, the servo motor 11 at the bottom of the placement rack 8 converts the received electrical energy into mechanical energy under the action of the external controller. The servo motor 11 drives the threaded rod 16 to rotate. The threaded sleeve 15 outside the threaded rod 16 moves laterally outside the threaded rod 16 under the action of the external limiting structure. Then, the drive frame 21 outside the threaded sleeve 15 drives the fixing plate 4 to move, so that the fixing plate 4 is moved out of the placement rack 8. Then, the aluminum alloy castings in the placement rack 8 enter the box 10 on the base 7, which facilitates the collection and processing of the heat-treated aluminum alloy castings and improves the heat treatment efficiency of the aluminum alloy castings.

[0034] When the cylinder 3 drives the transmission frame 20 to move, the limiting block 6 outside the transmission frame 20 slides in the limiting groove 5 opened on the heat treatment furnace 2, and at the same time the transmission frame 20 slides outside the fixed rod 1, thereby improving the stability of the movement of the transmission frame 20.

[0035] When the cover 9 is moved to the outside of the heat treatment furnace 2, the rubber gasket 18 inside the cover 9 comes into contact with the surface of the heat treatment furnace 2, thereby improving the sealing between the cover 9 and the heat treatment furnace 2.

[0036] When the drive frame 21 moves the fixed plate 4, the fixed sleeve 17 outside the drive frame 21 slides outside the support rod 12, and at the same time the connecting block 13 outside the fixed plate 4 slides in the groove 14 opened in the placement frame 8, thereby improving the stability of the drive frame 21 moving the fixed plate 4.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
