Description

Technical Field

[0001] This utility model belongs to the technical field of quenching equipment, specifically relating to a quenching device for automatic workpiece die fitting. Background Technology

[0002] Quenching is the process of heating a metal workpiece to a certain temperature and then suddenly placing it in water, oil, or cold air to cool it, thereby increasing its hardness. To produce metal workpieces with higher hardness, they are often quenched in a quenching furnace at the later stage of the heat treatment process to improve the product's hardness, surface finish, and other properties.

[0003] However, after the quenching process, the workpiece will undergo volume or shape distortion. Currently, existing technologies lack a fully automatic structural design that can automatically mold and demold the workpiece in the heating furnace to avoid deformation during quenching, resulting in inconsistent heat treatment quality of the workpiece. Utility Model Content

[0004] The purpose of this invention is to address the defects and shortcomings in the existing technology by designing an automatic workpiece molding quenching device. This device has a simple structure, is stable and reliable, and can enable workpieces to be molded and demolded inside the quenching tank, thereby reducing the deformation of the workpiece during quenching.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a quenching device for automatic workpiece mold fitting, comprising a quenching tank and a frame body disposed outside the quenching tank, a lifting platform for placing the workpiece and the mold is disposed above the quenching tank, the workpiece and the mold can move up and down under the action of the lifting platform, positioning components are disposed on the left and right sides of the frame body, the positioning components are used for concentric positioning of the workpiece and the mold, and a lifting component is disposed on the top of the frame body, the workpiece can move up and down under the action of the lifting component, thereby realizing its fitting into or unfitting from the mold.

[0006] Preferably, a sealing plate and a protective cover are provided between the positioning component and the frame body.

[0007] Preferably, the positioning assembly includes a push rod and a motor for driving the push rod to move left and right in the horizontal direction, and the end of the push rod has an arc-shaped push head that cooperates with the side wall of the workpiece.

[0008] Preferably, the positioning component further includes a limit switch electrically connected to the motor.

[0009] Preferably, the surface of the lifting platform is provided with multiple non-powered rollers.

[0010] Preferably, the lifting component is positioned in the middle of the two positioning components, and the moving direction of the lifting component is perpendicular to the moving direction of the positioning component.

[0011] Preferably, the lifting assembly includes a mechanical claw that cooperates with the workpiece. The mechanical claw can move up and down under the action of its driving component, and a torque sensor is also provided on the mechanical claw.

[0012] After adopting the above technical solution, the quenching device for automatic workpiece die fitting provided by this utility model has the following beneficial effects:

[0013] This invention utilizes a two-positioning component design to ensure that both push rods simultaneously and at the same speed push the workpiece towards the center, guaranteeing its centered positioning. The limit switch design allows adjustment of the push rod stroke to accommodate workpieces of various sizes. The sealing plate and protective cover design prevent steam generated during quenching from leaking out through gaps in the push rods. The arc-shaped push head design better conforms to the surface of circular workpieces, preventing slippage. The mechanical claw design moves the workpiece up and down for mold fitting and demolding actions, and a torque sensor detects whether the claw has engaged the workpiece. The design of the unpowered rollers on the lifting platform reduces the thrust required for the positioning components to move the workpiece. Therefore, this invention offers advantages such as simple structure, stability, reliability, and the ability to perform mold fitting and demolding of the workpiece within the quenching tank, minimizing deformation during quenching.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0022] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.

[0025] This utility model relates to an automatic workpiece die-fitting quenching device, such as... Figure 1-4 As shown, the system includes a quenching tank 1 and a frame body 2 located outside the quenching tank 1. A lifting platform 5 is provided above the quenching tank 1 for placing workpieces 3 and molds 4. The workpieces 3 and molds 4 can move up and down under the action of the lifting platform 5. Positioning components are provided on the left and right sides of the frame body 2. The two positioning components are symmetrically arranged for concentric positioning of workpieces 3 and molds 4. Specifically, the positioning components include a push rod 8 and a motor 9 for driving the push rod 8 to move left and right in the horizontal direction. The workpiece 3 is a circular workpiece. The end of the push rod 8 has an arc-shaped push head 10 that matches the side wall of the workpiece 3. This design can better fit the surface of the circular workpiece 3 and prevent the workpiece 3 from slipping. The positioning components also include a limit switch electrically connected to the motor 9. The limit switch can adjust the stroke of the push rod to handle circular workpieces of various sizes. Furthermore, a sealing plate 6 and a protective cover 7 are provided between the positioning components and the frame body 2 to ensure that the steam generated during quenching does not leak out through the gaps at the connection. In order to reduce the thrust required by the positioning components to move the workpiece 3, multiple non-powered rollers are provided on the surface of the lifting platform 5.

[0026] A lifting assembly is provided on the top of the frame body 2. The workpiece 3 can move up and down under the action of the lifting assembly, thereby realizing its insertion or release from the mold 4. The lifting assembly is located in the middle of the two positioning assemblies, and the moving direction of the lifting assembly is perpendicular to the moving direction of the positioning assemblies. Specifically, the lifting assembly includes a mechanical claw 11 that cooperates with the workpiece 3. The mechanical claw 11 can move up and down under the action of its driving component, and a torque sensor 12 is also provided on the mechanical claw 11 to sense whether the mechanical claw 11 hooks the workpiece 3, so as to ensure the stability of the lifting.

[0027] In use, the automatic workpiece mold-fitting quenching device of this utility model involves placing the workpiece 3 onto the lifting platform 5 using a forklift, pushing the two push rods 8 towards the center to ensure the workpiece 3 is in the middle position, resetting the push rods 8, and then the mechanical hook 11 hooks the lifting rod on the workpiece 3 to lift it up. Next, the mold 4 is placed onto the lifting platform 5 using a forklift, pushing the two push rods 8 towards the center to ensure the mold 4 is in the middle position, and then the mechanical hook 11 moves the workpiece 3 downwards to place it into the mold 4 to complete the pre-quenching mold fitting. The push rods 8 then reset, and the mechanical hook 11 releases the workpiece 3 and resets. The lifting platform 5 then lowers the workpiece 3 and mold 4 into the cooling liquid of the quenching tank 1 for quenching. The cooling liquid is either quenching oil or quenching salt. After quenching, the lifting platform 5 raises the workpiece 3 and mold 4, and the mechanical hook 11 hooks the lifting rod on the workpiece 3 to lift it up, thus completing the demolding after quenching.

[0028] In summary, the workpiece automatic mold-fitting quenching device provided by this utility model has a simple structure and is easy to operate. It can realize the mold-fitting and demolding actions of the workpiece inside the quenching tank, reduce the deformation of the workpiece during quenching, solve the problem of inconsistent heat treatment quality of workpieces, and has great market value. It is worthy of widespread promotion and application.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
