Abstract
The invention relates to a production method for a general valve rocker. The method includes the following steps of blanking, stretching, edge cutting, edge flanging, bending, punching, spherical face finishing, carbonitriding and polishing. The production method for the general valve rocker is provided and has the advantage that the problems that the appearance of a general valve rocker is poor, the spherical face is not round, the spherical wall is too thin and the spherical center is not accurate are solved.
Description
Technical field
The present invention relates to a kind of production method of general valve rocker.
Background technology
Existing valve rocker production technology mining method is as follows: 1. Blanking; 2. trimming; 3. forming and punching; 4. quench; 6 polishings; The product surface that this production method is produced is pulled, the sphere that key performance requires is not round, sphere center position is inaccurate, sphere wall thickness is excessively thin, this result has a strong impact on the assembling of valve lifter, and loose contact after assembling, causes general purpose engine noise excessive, and general purpose engine cacophonia, more seriously affects engine discharge not up to standard.Finally cause engine life greatly to reduce.Thereby surface is pulled and is crossed Bao Haihui with sphere wall thickness and cause valve rocker fracture to cause security incident.
Summary of the invention
In view of the above-mentioned problems in the prior art, main purpose of the present invention is to address the deficiencies of the prior art, the invention provides a kind of production method of general valve rocker, this production method has solved general valve rocker bad order, sphere, and circle, ball wall are not crossed problem thin and that the centre of sphere is inaccurate.
The production method that the invention provides a kind of general valve rocker, comprises the following steps: blanking, stretching, trimming, flange, bending, punching, finishing sphere, carbo-nitriding and polishing.
Optionally, in described stretching step, blanking stretched respectively for the first time and stretch for the second time.
Optionally, in described finishing sphere step, process sphere with high accuracy customization steel ball, form high-precision sphere.
Optionally, in described punching step, the rocking arm after bending is carried out to forming and punching.
The present invention has the following advantages and beneficial effect: the production method of a kind of general valve rocker provided by the invention, change quenching technical by splitting original process and increasing technological process, solved and produced the bad order, sphere of general valve rocker circle, ball wall are crossed problem thin and that the centre of sphere is inaccurate.
Brief description of the drawings
Fig. 1 is the flow chart of the production method of the general valve rocker of the embodiment of the present invention.
Detailed description of the invention
The present invention is further illustrated with specific embodiment below with reference to accompanying drawings.
As shown in Figure 1: the production method of a kind of general valve rocker of the embodiment of the present invention, comprise the following steps: blanking 1, stretch 2, trimming 3, flange 4, bending 5, punching 6, finishing sphere 7, carbo-nitriding 8 and polishing 9, the general valve rocker after this production method has solved to be produced bad order, the sphere of general valve rocker circle, ball wall is crossed problem thin and that the centre of sphere is inaccurate.
As the preferred embodiment of above-described embodiment, in described stretching 2 steps, blanking is stretched respectively for the first time and stretch for the second time, after twice stretching, the precision of workpiece is higher.
As the preferred embodiment of above-described embodiment, in described finishing sphere 7 steps, process sphere with high accuracy customization steel ball, form high-precision sphere, the precision of the general valve rocker after high accuracy customization steel ball processing is higher.
As the preferred embodiment of above-described embodiment, in described punching 6 steps, the rocking arm after bending is carried out to forming and punching.
Finally it should be noted that: above-described each embodiment, only for technical scheme of the present invention is described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record previous embodiment is modified, or to wherein partly or entirely technical characterictic be equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
