Description

Technical Field

[0001] The utility model relates to the technical field of spring production, in particular to a manual diameter reducing tool for a circlip. Background Art

[0002] The spring rebounds after coiling or pulls against each other during transportation, which will cause the middle opening of the spring to become larger, resulting in an increase in the inner diameter and making the spring unqualified. Therefore, the spring with an enlarged inner diameter needs to be necked down to meet the standards. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a manual necking tool for the retaining spring, which realizes the manual necking operation of the retaining spring through the cooperation between the base and the pressing column, thereby improving the problem of high deformation loss rate of the retaining spring.

[0004] In order to solve the above technical problems, the utility model provides a technical solution: a manual reducing tool for a retaining spring, comprising a base and a pressing column, characterized in that: a conical hole is provided on the base, the pressing column comprises a large end and a small end with different diameters, and the diameter of the large end is smaller than the diameter of the expanded end of the conical hole and larger than the diameter of the middle part of the conical hole, the diameter of the small end is loosely matched with the diameter of the contracted end of the conical hole, and the height of the pressing column is greater than the height of the base.

[0005] Furthermore, a circular groove is provided on one side of the base, the circular groove is connected to the necked end of the tapered hole, and the diameter of the circular groove is larger than the diameter of the necked end of the tapered hole.

[0006] The beneficial effects of the utility model are:

[0007] 1. This application places the retaining spring into the expanded end of the tapered hole on the base through the cooperation between the base and the pressing column, and then pushes the retaining spring from the expanded end of the tapered hole to the contracted end through the two ends of the pressing column, thereby realizing the contraction operation of the retaining spring, adjusting the deformed retaining spring, and reducing the loss rate of the retaining spring.

[0008] 2. In this application, the circular groove is connected to the shrinking end of the tapered hole, which limits the retaining spring when it comes out of the shrinking end to prevent the retaining spring from being suddenly released and splashing.

[0009] In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, preferred embodiments are given below and described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following describes embodiments of the present invention in detail with reference to the accompanying drawings. Although certain embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present invention. It should be understood that the accompanying drawings and embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0018] It should be understood that the steps described in the method embodiments of the present invention may be performed in a different order. Furthermore, the method embodiments may include additional steps or omit the steps shown. The scope of the present invention is not limited in this respect.

[0019] The names of the messages or information exchanged between multiple devices in the embodiments of the present invention are only used for illustrative purposes and are not used to limit the scope of these messages or information. Example 1

[0020] like Figure 1-4As shown, a manual diameter reducing tool for a retaining spring includes a base 1 and a pressing column 2. A conical hole 3 is provided on the base 1. The pressing column 2 includes a large end and a small end with different diameters. The diameter of the large end is smaller than the diameter of the expanded end of the conical hole 3 and larger than the diameter of the middle part of the conical hole 3. The diameter of the small end is loosely matched with the diameter of the contracted end of the conical hole 3. The height of the pressing column 2 is greater than the height of the base 1. The retaining spring A is placed in the expanded end of the conical hole 3 on the base 1, and then the retaining spring A is pushed from the expanded end to the contracted end of the conical hole 3 through the two ends of the pressing column 2 to realize the contraction operation of the retaining spring A, adjust the deformed retaining spring A, and reduce the loss rate of the retaining spring A.

[0021] The expanded end and the contracted end of the tapered hole 3 are set according to the size of the circlip A. The contracted end is the standard size of the circlip A, and the expanded end allows the deformed circlip A to be placed right at the expanded end. Example 2

[0022] like Figure 3 As shown, this embodiment is obtained by adding technical features such as a circular groove 4 on the basis of Example 1. The remaining technical features are the same as those of Example 1, and the similarities are not repeated here. Among them, the difference between this embodiment and Example 1 is that: a circular groove 4 is provided on one side of the base 1, and the circular groove 4 is connected to the necked end of the tapered hole 3, and the diameter of the circular groove 4 is larger than the diameter of the necked end of the tapered hole 3.

[0023] In this embodiment, the circular groove 4 is connected to the conical hole 3, and the retaining spring A is limited when it comes out of the conical hole, so as to prevent the retaining spring A from being suddenly released and splashing.

[0024] The usage process of the overall technical solution formed by the above embodiments is as follows: put the retaining spring A into the flared end of the tapered hole 3 on the base 1, put the large end of the pressing column 2 on the retaining spring A and extend it into the tapered hole 3, and the retaining spring A gradually shrinks under the push of the pressing column 2, and then take out the pressing column 2 and use the small end of the pressing column 2 to extend from the flared end of the tapered hole 3 and press on the retaining spring A, and push the retaining spring A to continue to move toward the shrinking end of the tapered hole 3 until the retaining spring A moves out from the shrinking end, completing the shrinking operation of the retaining spring A.

[0025] Note that the above are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are readily apparent to those skilled in the art without departing from the scope of protection of the present invention. Therefore, while the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the scope of the present invention. The scope of the present invention is determined by the appended claims.
