Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing technology, and in particular to an aging tooling for spring parts. Background Technology

[0002] Heat treatment aging refers to placing metal workpieces that have undergone solution treatment or cold plastic deformation at room temperature or a higher temperature for an appropriate time to improve their mechanical properties and microstructure changes over time. This can lead to phenomena such as material hardening, springback, and phase transformation, thereby improving the material's strength, hardness, and corrosion resistance.

[0003] During the heat treatment aging process of springs, the springs need to be compressed to a specified height and fixed, and then kept in a high-temperature aging oil bath for several hours or more. However, due to the different sizes of springs and the different diameters of spring steel wires, the rebound force of various springs is different. Moreover, the production quantity of springs is large. If the compression of the springs is not guaranteed, the aging treatment effect of the springs will be poor, the product quality cannot be guaranteed, and the production efficiency will be low when the number of springs is large. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides an aging fixture for spring-type parts.

[0005] This utility model discloses the following technical solution: an aging fixture for spring-type parts, including a fixed post, a guide post, a support plate, a pressure plate, and a nut. The fixed post is fixedly installed on the support plate, and the guide post is detachably installed on the support plate. Both the fixed post and the guide post are perpendicular to the support plate. The pressure plate has through holes through which the fixed post and the guide post can pass. The upper end of the fixed post is threaded. The pressure plate is installed on the fixed post using a nut. The pressure plate is horizontal with the support plate.

[0006] Furthermore, there are four fixing columns, which are installed at the four corners of the support plate.

[0007] Furthermore, the guide posts are a plurality of each other and are arranged in an array on the support plate.

[0008] Furthermore, the guide post is threaded onto the support plate.

[0009] Furthermore, the guide post and the through hole on the pressure plate are fitted with a clearance, allowing the pressure plate to slide freely on the guide post.

[0010] Beneficial effects: Compared with the prior art, the aging fixture for spring parts of this utility model, by setting fixed columns and guide columns on the support plate, and installing pressure plates on the fixed columns by nuts, allows the springs to be fitted onto the guide columns during heat treatment aging of spring parts. The spring compression length is adjusted by adjusting the distance between the pressure plate and the support plate by the nuts, ensuring the spring compression amount and improving the effect of heat treatment aging. In addition, setting several guide columns allows multiple springs to be processed at the same time, resulting in high production efficiency. Attached Figure Description

[0013] In the diagram: 1-fixed column, 2-guide column, 3-support plate, 4-pressure plate, 5-nut. Detailed Implementation

[0014] like Figures 1 to 2 As shown, an aging fixture for spring-type parts includes a fixed post 1, a guide post 2, a support plate 3, a pressure plate 4, and a nut 5. The fixed post 1 is fixedly installed on the support plate 3, and the guide post 2 is detachably installed on the support plate 3. Both the fixed post 1 and the guide post 2 are perpendicular to the support plate 3. The pressure plate 4 has through holes through which the fixed post 1 and the guide post 2 can pass. The upper end of the fixed post 1 is threaded. The nut 5 is used to install the pressure plate 4 on the fixed post 1. The pressure plate 4 is horizontal with the support plate 3.

[0015] Four fixing posts 1 are installed at the four corners of the support plate 3 to keep the pressure plate 4 horizontal with the support plate 3 and ensure that the spring compression on the tooling is consistent. Several guide posts 2 are arranged in an array on the support plate 3, which can simultaneously perform aging treatment on multiple springs and improve production efficiency. The guide posts 2 are installed on the support plate 3 by threads. When the spring specifications are different, the guide posts 2 corresponding to the spring need to be replaced. The threaded installation method facilitates the disassembly and assembly of the guide posts 2 and improves the versatility of the tooling. The guide posts 2 are clearance-fitted with the through holes on the pressure plate 4, and the pressure plate 4 can slide freely on the guide posts 2, which facilitates the adjustment of the distance between the pressure plate 4 and the support plate 3.

[0016] In use, select a guide post 2 of appropriate diameter according to the spring specifications and install it on the support plate 3 to ensure that the spring does not easily shift. Fit the spring to be processed onto the guide post 2. The pressure plate 4 passes through the fixed post 1 and the guide post 2, so that the pressure plate 4 and the support plate 3 press the spring down. Tighten the nut 5 onto the fixed post 1. Adjust the distance between the pressure plate 4 and the support plate 3 by turning the nut 5 according to the required compression of the spring. The adjustment of the four nuts 5 should be the same, or use calipers or other measuring tools to measure the distance between the support plate 3 and the pressure plate 4 in four directions and adjust the nuts 5 to make the distances in four directions equal to ensure that the compression of the spring is consistent. Then, place the fixture with the spring in a high-temperature aging oil bath for treatment. Using this fixture can ensure that the spring is at a high compression height for a long time, resulting in good aging treatment effect. At the same time, processing multiple springs can effectively improve production efficiency.

[0017] 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. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
