Description

Technical Field

[0001] This utility model belongs to the field of steel casting production technology, and in particular relates to a heat treatment device for the production of metal steel castings. Background Technology

[0002] Chinese patent CN218310812U discloses a heat treatment device for producing metal steel castings. The device includes a main body with a sealing cover on its upper outer surface and a cooling mechanism on one outer surface. Inside the main body are a top-loading mechanism and a cavity, with the cavity located outside the top-loading mechanism. An operation panel is located on the front outer surface of the main body. This heat treatment device effectively cools the castings inside the device through its cooling mechanism, improving cooling efficiency. The top-loading mechanism facilitates removal of the castings, enhancing user convenience. The cylinder, when activated, drives a pusher plate to move up and down, pushing the castings out of the device for easy access, thus improving its future application prospects.

[0003] However, in the above-mentioned solutions, metal steel castings usually need to undergo quenching and cooling treatment during the production process to improve the material's microstructure and mechanical properties. The existing quenching and cooling methods mostly involve placing the workpieces one by one in the coolant for cooling, and then taking them out one by one for transport after cooling. This method is not only cumbersome and inefficient, but also prone to workpiece instability during manual operation, which affects the consistency of quenching. In addition, the traditional equipment has a relatively simple connection between workpiece feeding and discharging, which cannot achieve continuous and stable workpiece entry into the cooling zone from the feeding end and smooth transport to the discharging end. It often requires additional manual assistance, which increases manpower input and affects the overall production cycle. Utility Model Content

[0004] This utility model provides a heat treatment device for the production of metal steel castings, which aims to solve the problem that the existing quenching and cooling methods mostly involve placing the workpieces one by one in the coolant for cooling, and then taking them out one by one for transportation after cooling. This method is not only cumbersome and inefficient, but also prone to workpiece instability during manual operation, which affects the consistency of quenching.

[0005] This utility model is implemented as follows: a heat treatment device for producing metal steel castings includes a quenching box, a drain pipe installed outside the quenching box, a feeding device installed inside the quenching box, and a discharging device installed inside the quenching box.

[0006] The feeding device includes a drive motor, and a reciprocating lead screw is installed at the output end of the drive motor. A threaded cap is provided on the outer sleeve of the reciprocating lead screw, and a mounting frame is fixedly connected to the outside of the threaded cap. A roller assembly is fixedly connected inside the mounting frame.

[0007] Preferably, the feeding device further includes a frame, which is fixedly connected inside the quenching box. A connecting frame is fixedly connected inside the frame, the drive motor is fixedly connected to the bottom of the connecting frame, and the reciprocating lead screw is rotatably connected inside the connecting frame.

[0008] Preferably, guide rails are symmetrically mounted on the front of the frame, and sliders are fitted over the guide rails and fixedly connected to the back of the mounting frame.

[0009] Preferably, the threaded cap has a rectangular cross-section, and one side of the rectangle overlaps the inner wall of the quenching box.

[0010] Preferably, the front of the connecting frame is symmetrically equipped with stop bars for limiting the movement of the slider.

[0011] Preferably, the discharge device includes an inclined frame, which is fixedly connected inside the quenching box. A bucket conveyor is installed inside the inclined frame, and several push plates are fixedly connected to the outside of the bucket conveyor.

[0012] Preferably, the roller assembly is connected to the bucket conveyor.

[0013] Compared with related technologies, the heat treatment device for producing metal steel castings provided by this utility model has the following advantages:

[0014] This invention achieves automation and high efficiency in the quenching and cooling of metal steel castings through the following structural design: In operation, the drive motor is first started, which drives the reciprocating screw to rotate. During rotation, the screw drives the threaded cap to move axially, causing the mounting frame and roller assembly to reciprocate synchronously. After the roller assembly moves out of the coolant, the workpiece to be processed can be placed above the roller assembly. By reversing the drive motor, the threaded cap moves in the opposite direction, thus driving the roller assembly into the quenching chamber and connecting it with the bucket conveyor. At this time, the roller assembly, during rotation, can drive the workpiece to the bucket conveyor. The workpiece can complete the cooling process during transport. The pusher plate on the bucket conveyor further lifts and transports the workpiece gradually, achieving discharge. Through the above operation process, this invention achieves continuous operation from workpiece feeding to quenching and cooling to discharge, avoiding the cumbersome steps of individual workpiece operation in traditional methods, significantly improving cooling efficiency, and ensuring the stability and consistency of the workpiece during cooling and transport.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] Example 1

[0023] A preferred embodiment of the heat treatment apparatus for producing metal steel castings provided by this utility model is, for example... Figures 1 to 4 As shown: A heat treatment device for producing metal steel castings includes a quenching box 1, a drain pipe 2 installed outside the quenching box 1, a feeding device 3 installed inside the quenching box 1, and a discharge device 4 installed inside the quenching box 1.

[0024] The feeding device 3 includes a drive motor 303, a reciprocating screw 304 is installed at the output end of the drive motor 303, a threaded cap 305 is provided on the outer sleeve of the reciprocating screw 304, a mounting frame 306 is fixedly connected to the outer sleeve of the threaded cap 305, and a roller group 309 is fixedly connected inside the mounting frame 306.

[0025] In this embodiment, the roller assembly 309 is fixed inside the mounting frame 306. The stable support of the mounting frame 306 can prevent the roller assembly 309 from swaying under force, making the roller rotation more stable, effectively supporting the weight of the workpiece and reducing frictional resistance, thereby improving the moving efficiency of the workpiece during the unloading process.

[0026] In a further preferred embodiment of this utility model, the feeding device 3 further includes a frame 301, which is fixedly connected inside the quenching box 1. A connecting frame 302 is fixedly connected inside the frame 301. A drive motor 303 is fixedly connected below the connecting frame 302. A reciprocating screw 304 is rotatably connected inside the connecting frame 302. A guide rail 307 is symmetrically installed on the front of the frame 301. A slider 308 is sleeved on the guide rail 307. The slider 308 is fixedly connected to the back of the mounting frame 306. The threaded cap 305 has a rectangular cross-section, and one side of the rectangle overlaps the inner wall of the quenching box 1.

[0027] In this embodiment, the cross-section of the threaded cap 305 is designed to be rectangular, and one side overlaps the inner wall of the quenching box 1. This overlapping method can guide and prevent rotation when the threaded cap 305 moves along the screw, avoiding the threaded cap 305 from deflecting or shaking when subjected to force, thereby ensuring the linear movement accuracy of the mounting frame 306 and the roller group 309 and improving the stability of the feeding action.

[0028] In a further preferred embodiment of this utility model, the front of the connecting frame 302 is symmetrically equipped with stop bars for limiting the movement of the slider 308. The discharge device 4 includes an inclined frame 401, which is fixedly connected to the quenching box 1. A bucket conveyor 402 is installed inside the inclined frame 401. Several push plates 403 are fixedly connected to the outside of the bucket conveyor 402. The roller group 309 overlaps with the bucket conveyor 402.

[0029] In this embodiment, the stop bars symmetrically arranged on the front of the connecting frame 302 cooperate with the slider 308 to limit the slider 308 when it moves to the extreme position, preventing the mounting frame 306 and the roller group 309 from exceeding the predetermined stroke. This protects the drive motor 303 and the lead screw from overload damage and ensures that the roller group 309 and the bucket conveyor 402 can be accurately docked.

[0030] In summary, the following structural design achieves automation and high efficiency in the quenching and cooling of metal steel castings: During operation, the drive motor 303 is first started, driving the reciprocating screw 304 to rotate. During rotation, the screw 304 drives the threaded cap 305 to move axially. The threaded cap 305 drives the mounting frame 306 and the roller assembly 309 to move synchronously back and forth. After the roller assembly 309 moves out of the coolant, the workpiece to be processed can be placed on top of it. Subsequently, by reversing the start of the drive motor 303, the threaded cap 305 moves in the opposite direction, thereby driving the roller assembly 309 to move forward. The workpiece is placed into the quenching box 1 and connected to the bucket conveyor 402. At this time, the roller group 309 can drive the workpiece to move to the bucket conveyor 402 during rotation. The workpiece can be cooled during the conveying process. The push plate 403 on the bucket conveyor 402 further lifts and conveys the workpiece to achieve discharge. Through the above operation process, this utility model realizes the continuous operation of the workpiece from unloading to quenching and cooling and then to discharge, avoiding the cumbersome steps of operating each workpiece individually in the traditional method, greatly improving the cooling efficiency, and ensuring the stability and consistency of the workpiece during the cooling and conveying process.
