Abstract
The invention discloses a production method of an adjusting nut of a light car differential, which is characterized by adopting a punch for punching the adjusting nut. The weight of the adjusting nut of the light car differential, produced by the method is only 220g and reduced by 40g than before, the price is only 2.1 yuan and reduced by 1.8 yuan than before, and the economic benefit is extremely obvious. More important, the adoption of the punching method does not have influence on environment substantially, while the adopted traditional casting method influences environment seriously.
Description
Technical field
The present invention relates to a kind of production method of light car differential gear adjustment-nut.
Background technology
At present, the housing of light car differential gear and part all adopt nodular iron casting, comprise that differential gear adjustment-nut sees Fig. 1.The finished weight of differential gear adjustment-nut has only 280g, and blank weight is 400g, the waste product that adds cast gate, rising head and cause because of casting flaw, and raw-material comprehensive utilization ratio is approximately about 60%.Current, the control of industrial production environmental pollution is all being strengthened and to making full use of of resource and effort in countries in the world by variety of way.
Summary of the invention
At the deficiency of prior art, the invention provides a kind of production method of light car differential gear adjustment-nut.
Below introduce the production method of a kind of light car differential gear adjustment-nut of the present invention in detail, adopt punch ram to adjust nut.
Advantage of the present invention is to adopt the light car differential gear adjustment-nut weight of this method production 220g only to be arranged than the original 40g of minimizing, and price is 1.8 yuan of the original minimizings of 2.1 yuan of ratios; The economic benefit highly significant.More outstanding is to adopt the method for punching press to almost not influence of environment, and adopts traditional casting method environmental pollution serious.
Description of drawings
Fig. 1 adjusts the structural representation of nut for cast type before the present invention;
Fig. 2 adjusts the structural representation of nut for punching type of the present invention.
The specific embodiment
Below in conjunction with Figure of description the present invention is done further disclosure.
Embodiment 1:
See also Figure of description 2, a kind of production method of light car differential gear adjustment-nut, the method for the punch ram that employing is conventional is adjusted nut according to the dimensional requirement punching press.
Concrete steps are: at first that 6mm is thick steel plate size blanking as requested is circular 1, and bending makes the circular steel plate flange 2 that makes progress then, and the size of flange is determined according to the requirement of nut; Steel plate behind the flange is moved to stamping machine, the aperture 4 of circumference uniform distribution around the macropore at a punching press center and the macropore 3; At last with the position of the steel plate flange after the punching with screw thread on the tool makings such as lathe; Become the adjustment nut.
Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited to aforesaid operations, and all variations of making in essential scope of the present invention, remodeling, interpolation or replacement all should belong to protection scope of the present invention.
