Description

Technical Field

[0001] This application relates to the technical field of quenching tooling, and in particular to a washer and a carburizing and quenching tooling for gears. Background Art

[0002] When heat-treating and quenching medium and large-sized steel disc-shaped parts, in order to ensure the uniformity and consistency of multiple parts in the same furnace during the heating and quenching cooling processes, the parts are generally stacked when mounted on the tire, and generally circular, square or other integral washer toolings are used to support and separate the parts.

[0003] However, the quality of washer installation directly affects the heat treatment deformation of the parts, and the flatness of the base and washer and the consistency of the height dimensions directly affect the quality of part washer installation. During actual production and use, the base or washer tooling will inevitably produce varying degrees of deformation after repeated heat treatment. During actual production, in order to ensure that the part washer is at the same horizontal height, thin gaskets are often added to the uneven places between the parts and the washer for auxiliary washer installation. However, the cumulative error increases during the long-term heating process, and the parts warp and distort due to unstable washer installation, resulting in uneven machining allowances of the parts after heat treatment, and even the parts cannot be processed into finished products, causing part scrapping. Summary of the Utility Model

[0004] In order to improve the problem that when parts are heat-treated and quenched, the base or washer tooling produces varying degrees of deformation after repeated heat treatment, thin gaskets are added to the uneven places between the parts and the washer for auxiliary washer installation, but the cumulative error increases during the long-term heating process, and the parts warp and distort due to unstable washer installation, resulting in uneven machining allowances of the parts after heat treatment, and even the parts cannot be processed into finished products, causing part scrapping, this application provides a washer and a carburizing and quenching tooling for gears.

[0005] The washer and the carburizing and quenching tooling for gears provided by this application adopt the following technical solutions:

[0006] In a first aspect, this application provides a washer, including a washer body, the washer body includes a first component and a second component, a convex spherical surface is provided on a surface of the first component close to the second component, and a concave spherical surface adapted to the convex spherical surface is provided on a surface of the second component close to the first component; when the convex spherical surface is inserted into the concave spherical surface, a gap is spaced between the first component and the second component.

[0007] By adopting the above technical solution, when the washer body is in use, first install the washer on the gear carburizing and quenching tooling. The first part and the second part of the washer body are in spherical contact and support, enabling adjustment in any direction and angle within a certain range. Thus, when heat-treating and supporting steel disc-shaped parts, even if there are certain differences in the flatness of the base or the height dimension of the washer tooling, the washer body can always be in a plane through its feature of "adjustment in any direction and angle within a certain range", thereby achieving good support for the parts to be installed, reducing the heat treatment deformation of the parts, reducing the unevenness of the machining allowance of the parts after heat treatment, and improving the product quality.

[0008] Optionally, a plurality of grooves are formed on the surfaces of the first part and the second part facing away from each other.

[0009] By adopting the above technical solution, the contact surface between the tooling and the part can be reduced to minimize the influence of the contact surface of the washer body on the quenching effect of the part.

[0010] Optionally, there are multiple grooves and they are strip-shaped, and the multiple grooves are arranged in a cross pattern.

[0011] Optionally, both ends of the groove penetrate through the side wall of the washer body.

[0012] By adopting the above technical solution, it is convenient to clean the debris falling into the groove.

[0013] In a second aspect, the present application provides a gear carburizing and quenching tooling, including the above-described washer, and further including a base and a suspension rod. The suspension rod is fixedly connected to the middle of the top surface of the base, and the suspension rod is inserted into the part to be processed. The base and the part are supported and connected by at least two washer bodies, and the parts are also supported and connected by at least two washer bodies.

[0014] By adopting the above technical solution, when the quenching tooling of the present application is in use, the first part and the second part cooperate with each other, and the upper and lower positions of the first part and the second part can be interchanged. The weight of the upper part will be transmitted to the second part and the part under the second part through the convex spherical surface. Therefore, the contact end surface between the second part and the part can be in good planar contact with the lower part, and since the first part is in spherical contact and support with the second part, the first part can achieve adjustment in any direction and angle within a certain range.

[0015] Optionally, the base and the part are supported and connected by three washer bodies, and the parts are also supported and connected by three washer bodies.

[0016] By adopting the above technical solution, when using the quenching tooling of the present application for three-point support padding of parts, since the quenching tooling can be adjusted in any direction and angle within a certain range, even if there are certain differences in the flatness of the base or the height dimension of the washer tooling, the planes of the three support positions of the quenching tooling can always be in a plane. Therefore, when padding the upper part, under the action of the self-weight of the upper part, the upper plane of the first component can be automatically leveled, thus achieving good support for the padded parts and reducing the heat treatment deformation of the parts.

[0017] In summary, the present application includes at least the following beneficial technical effects:

[0018] 1. The first component and the second component cooperate with each other. The upper and lower positions of the first component and the second component can be interchanged. The weight of the upper part will be transmitted to the second component and the parts under the second component through the convex spherical surface. Therefore, the contact end face of the second component with the parts can be in good planar contact with the lower parts. Since the first component is in spherical contact and support with the second component, the first component can be adjusted in any direction and angle within a certain range;

[0019] 2. The setting of the groove can reduce the contact surface between the tooling and the parts, so as to minimize the influence of the contact surface of the washer body on the quenching effect of the parts;

[0020] 3. When using the quenching tooling of the present application for three-point support padding of parts, even if there are certain differences in the flatness of the base or the height dimension of the washer tooling, the planes of the three support positions of the quenching tooling can always be in a plane. Therefore, when padding the upper part, under the action of the self-weight of the upper part, the upper plane of the first component can be automatically leveled, thus achieving good support for the padded parts and reducing the heat treatment deformation of the parts.

[0027] The following is combined with Figures 1-5 This application is described in further detail.

[0028] The embodiment of the present application discloses a carburizing and quenching tool for a washer and a gear.

[0029] First, refer to Figures 1-4 The present application provides a gasket, a gasket and a gear carburizing and quenching tooling, comprising a gasket body 1, the gasket body 1 comprising a first component 11 and a second component 2 arranged in a rectangular shape, a convex spherical surface 111 being arranged on a surface of the first component 11 close to the second component 2, and a concave spherical surface 21 matching the convex spherical surface 111 being arranged on a surface of the second component 2 close to the first component 11; when the convex spherical surface 111 is inserted into the concave spherical surface 21, a gap is provided between the first component 11 and the second component 2.

[0030] When the washer body 1 is used, the washer is first installed on the gear carburizing and quenching tooling. The first component 11 and the second component 2 of the washer body 1 are in spherical contact and support, and can be adjusted in any direction and angle within a certain range, thereby realizing the support and padding of the steel pancake-shaped part 6 during heat treatment. Even if there are certain differences in the flatness of the base 4 or the height size of the washer tooling, the washer body 1 can always be in the same plane through the feature of "adjustment in any direction and angle within a certain range", thereby achieving good support for the installed pad part 6, reducing the heat treatment deformation of the part 6, reducing the unevenness of the machining allowance of the part 6 after heat treatment, and improving product quality.

[0031] Reference Figures 1-4 A plurality of grooves 3 are provided on the surface of the first component 11 and the second component 2 which are away from each other, so as to reduce the contact surface between the tooling and the part 6, so as to minimize the influence of the contact surface of the gasket body 1 on the quenching effect of the part 6. There are multiple grooves 3 in the shape of strips, and multiple grooves 3 are arranged vertically and crosswise. Both ends of the grooves 3 penetrate the side wall of the gasket body 1, so as to facilitate the cleaning of objects dropped into the grooves 3.

[0032] In the second aspect, the present application provides a gear carburizing and quenching tool, referring to Figures 1-5 The gear carburizing and quenching tooling includes the above-mentioned gasket, and also includes a base 4 and a suspension rod 5. The suspension rod 5 is fixedly connected to the middle of the top surface of the base 4. The suspension rod 5 is inserted into the part 6 to be processed. The base 4 and the part 6 are supported and connected by at least two gasket bodies 1, and the parts 6 are also supported and connected by at least two gasket bodies 1.

[0033] When the quenching tooling of the present application is in use, the first component 11 and the second component 2 cooperate with each other. The up-and-down positions of the first component 11 and the second component 2 can be interchanged. The weight of the upper-end part 6 will be transmitted to the second component 2 and the part 6 under the second component 2 through the convex spherical surface 111. Therefore, the contact end face between the second component 2 and the part 6 can be in good planar contact with the lower-end part 6. And since the first component 11 is in spherical contact and support with the second component 2, the first component 11 can be adjusted in any direction and at any angle within a certain range.

[0034] Referring to Figure 5 , the base 4 and the part 6 are supported and connected by three washer bodies 1, and the part 6 and the part 6 are also supported and connected by three washer bodies 1. When using the quenching tooling of the present application for three-point support padding of the part 6, because the quenching tooling can be adjusted in any direction and at any angle within a certain range, even if there are certain differences in the flatness of the base 4 or the height dimension of the washer tooling, the planes of the three support positions of the quenching tooling can always be in a plane. Thus, when padding the upper-end part 6, under the action of the self-weight of the upper-end part 6, the upper-plane of the first component 11 can achieve automatic leveling, so as to achieve good support for the padded part 6, thereby reducing the heat treatment deformation of the part 6.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
