Problems solved by technology

[0004] In order to solve the technical problems that the existing production process of the circlip is relatively complex, the investment in personnel and equipment is large, the production cost is high, the degree of automation is low, and it is not suitable for mass production, the invention provides a production method of the circlip. The production method has a high degree of automation and less investment in personnel and equipment costs, which relatively reduces the unit production cost of the product, and one-time molding can effectively guarantee various technical parameters of the circlip and improve its yield

Embodiment Construction

[0028] The following further describes the embodiments of the present invention with reference to the accompanying drawings:

[0029] The present invention is a method for producing a circlip, which includes the following steps:

[0030] a. Cutting: Cut the steel coil of the required thickness into steel strips according to the required width. The width of the steel strip is larger than the width of the circlip, so that the width of the steel strip is larger than the width of the circlip, which can be convenient in one-time Automatic continuous operation of the forming process;

[0031] b. Feeding: Load the steel plate into the automatic feeder, and send one end of the steel belt into the progressive die installed on the hydraulic punch through the feeder; the feeding frequency of the feeder is the same as the punching frequency of the hydraulic punch and the feeding length The length of the station is the same as that of the progressive die. When the feeder feeds the steel belt int...

Abstract

The invention relates to a producing method of a snap spring. The technical problems of that existing snap springs are complex in producing craft, more in personnel input and equipment input, high in production cost, low in automation degree, not suitable for mass production and the like are mainly resolved. The producing method of the snap spring has the advantages that an auto feeder is used for feeding to a punch, and then the punch can carry out continuous stamping work through a progressive mould, once automation form of the snap spring is achieved. Compared with the prior art, the process is high in automation degree, capable of avoiding manual operation with many people and many orders. Quality is easy to control. Accuracy requirements of the snap spring can be ensured effectively. Secondly, a chamfer of the snap spring is finished directly through process optimization when the snap spring is formed, and then secondary operation after the snap spring is formed can be avoided, the equipment input and the personnel input are reduced correspondingly, production cost is reduced remarkably, and consistency of products is ensured during the mass production, and the yield of the snap spring is improved.

Description

Technical field [0001] The invention relates to a production process, more specifically to a production process of a circlip suitable for milling gears, and belongs to the field of engineering machinery. Background technique [0002] The circlip is one of the important parts used to connect the milling tooth and the drum of the milling machine. In the process of use, the circlip is set outside the tooth handle of the milling tooth and fixed on the drum of the milling machine. The card teeth of the milling teeth are connected with the barbs of the milling teeth to prevent the milling teeth from detaching from the milling gear drum; in order to ensure the service life of the milling teeth, the milling teeth need to rotate along the axis of the circlip, which can effectively prevent milling One side of the tooth wears too fast, prolonging the service life of the milling tooth; and in order to ensure the axial rotation of the milling tooth in use, this requires a higher size and accu...
