Description
Technical Field
The invention relates to a processing method of a fastening standard component, in particular to a processing method of a check ring.
Background
The retainer ring is a ring-shaped component fastened on the shaft and the inner hole, mainly used for preventing other components mounted on the shaft and the inner hole from axially sliding on the shaft, and is a fixed standard component.
The retainer ring is a ring-shaped body with an opening, and the traditional processing method is stamping. That is, a plate-shaped material is selected and punched out (a circular body is punched out from the middle of the circular body to form an annular ring body), and the material punched out from the middle cannot be reused, which results in waste of material.
In order to prevent the waste of materials, the technical personnel in the field select the processing materials as steel wires, and form an annular ring body by drawing the steel wires. If the announcement is: the invention name of CN103522009 is 'a method for processing a retainer ring'. The steel wire is used as a processing material, the processing is carried out in a drawing mode, the annealing is carried out after the steel wire is subjected to drawing forming, and the steel wire needs to be bundled after the annealing forming is finished. Because the cross section of the steel wire is rectangular, when the steel wire is drawn into the retainer ring base body, the cross section of the steel wire is changed due to the stress extrusion of materials, the inner ring of the retainer ring base body is higher than the outer ring (an inclined plane is formed), and because the extrusion deformation of the materials is larger, the stamping of the opening of the retainer ring base body can generate a corner collapse or cause larger material deformation; therefore, the retainer ring base body needs to be bundled, the bundling process is to prevent the material from being heated to generate larger deformation in the quenching process, and meanwhile, the bundling process also has a certain adjusting function in the quenching process to promote the inclined plane to be reduced; however, after quenching, the hardness of the retainer base is increased, and the punching process of the openings on the retainer base is more complicated.
Therefore, the processing method can be only used for processing the check ring which is simple (namely, the check ring is only a ring-shaped body, and cannot be cut or punched), and the outer surface of the processed check ring still cannot be ensured to be completely flat.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides the processing method of the check ring, which is convenient for punching, has a smooth outer surface and a simple processing process.
In order to achieve the purpose, the invention provides the following technical scheme: the processing method of the check ring is characterized by comprising the following steps: a. drawing the steel wire to a predetermined diameter; b. c, performing pressure drawing on the steel wire subjected to drawing in the step a through a press to enable the cross section of the steel wire to be in a trapezoid shape; c. annealing the steel wire subjected to the pressing and drawing in the step b; d. winding the steel wire subjected to annealing treatment in the step c to form a primary retainer ring matrix; e. punching the preliminarily formed retainer ring base body; f. and carrying out heat treatment and surface treatment on the punched retainer ring substrate to obtain a finished retainer ring.
By adopting the technical scheme, the steel wire is drawn and is pressed and drawn to be drawn to the preset diameter, so that the cross section of the steel wire is in a trapezoidal shape, the outer surface of the steel wire can be deformed when the subsequent winding is carried out to form the primary retainer ring matrix, and the deformation process is as follows: when the steel wire with the cross section in the shape of the trapezoid is wound, the body of the steel wire is stressed to deform, the material on the upper part of the trapezoid steel wire moves towards the lower part, the cross section of the retainer ring base body is enabled to be rectangular after winding, the outer surface of the retainer ring base body is kept flat, the retainer ring base body is subjected to punching at the moment, the use surface of the retainer ring is free from corner collapse and inclined edges, and the processing quality of the retainer ring base body is ensured; and then, the heat treatment is carried out on the retainer ring matrix subjected to punching, so that the retainer ring with a flat surface and guaranteed quality is processed, and the processing process is simpler and more convenient.
The invention is further configured to: and e, punching the station in the step e, wherein the punching station comprises an opening for the check ring, an inner ring and a hole at the opening.
By adopting the technical scheme, the processing method can be used for processing different check rings, and has strong universality.
The invention is further arranged as follows: and c, after the steel wire is annealed, performing secondary pressing and drawing on the steel wire again through a press to promote the steel wire with the trapezoidal cross section to be adjusted and shaped again.
By adopting the technical scheme, the steel wire with the trapezoidal cross section can be adjusted by performing secondary pressing and pulling on the steel wire, so that the steel wire is prevented from generating tiny deformation in the annealing process, and the cross section of the steel wire is kept in the trapezoidal shape.
The invention is further arranged as follows: the heat treatment in the step f comprises quenching treatment and tempering treatment, and the surface treatment is corrosion prevention treatment.
By adopting the technical scheme, the hardness and the corrosion resistance of the check ring can be improved by the arrangement, so that the service life of the check ring is prolonged.
The invention is further described below with reference to the accompanying drawings.

FIG. 1 is a schematic process flow diagram according to an embodiment of the present invention.
Detailed Description
The processing method of the retainer ring shown in fig. 1 comprises the following steps: a. drawing the steel wire to a predetermined diameter; b. c, performing pressure drawing on the steel wire subjected to drawing in the step a through a press to enable the cross section of the steel wire to be in a trapezoid shape; c. annealing the steel wire subjected to the pressing and drawing in the step b; d. winding the steel wire subjected to annealing treatment in the step c to form a primary retainer ring matrix; e. punching the preliminarily formed retainer ring base body; f. and carrying out heat treatment and surface treatment on the punched retainer ring substrate to obtain a finished retainer ring. In the above scheme, the steel wire is drawn and is pressed to draw after being drawn to the preset diameter, so that the cross section of the steel wire is in a trapezoidal shape, the outer surface of the steel wire can be deformed when the subsequent winding is carried out to form the primary retainer ring base body, and the deformation process is as follows: when the steel wire with the cross section in the shape of the trapezoid is wound, the body of the steel wire is stressed to deform, the material on the upper part of the trapezoid steel wire moves towards the lower part, the cross section of the retainer ring base body is enabled to be rectangular after winding, the outer surface of the retainer ring base body is kept flat, the retainer ring base body is subjected to punching at the moment, the use surface of the retainer ring is free from corner collapse and inclined edges, and the processing quality of the retainer ring base body is ensured; and then, the heat treatment is carried out on the retainer ring matrix subjected to punching, so that the retainer ring with a flat surface and guaranteed quality is processed, and the processing process is simpler and more convenient.
