thirdly, carrying out flash welding on the round hollow flat blank with the notch by using a base material to obtain a round hollow flat;
punching the round hollow flat plate in the third step by using an oil press to punch a middle hole and a threaded hole;
step five: spinning the round hollow flat plate by using powerful spinning equipment to obtain a semi-finished steel ring spoke plate product which is formed by an annular bottom plate positioned at the end part and a bent annular edge integrally formed with the annular end plate;
step six: carrying out air hole punching treatment on the semi-finished steel ring spoke plate through a lathe, and punching the semi-finished steel ring spoke plate to form air holes which are positioned at the bent annular edge and distributed annularly;
step seven: and (3) carrying out air hole deburring treatment, screw hole reaming treatment, chamfering treatment, hole turning treatment, end face turning treatment, outer circle turning treatment and inner hole turning treatment on the semi-finished steel ring web with the air holes, and finally obtaining a finished steel ring web.
The invention further improves that: cleaning the welding seam of the round hollow flat plate prepared in the third step by using a slag scraper, finely processing the welding seam of the round hollow flat plate by using an automatic grinding machine, shaping the round hollow flat plate by using rolling equipment for reverse spinning, and performing rounding processing by using automatic rounding equipment.
Compared with the prior art, the invention has the beneficial effects that:
the process replaces the traditional 'whole steel plate blanking' for the steel ring web with a 'near-net-shape steel rolling process', and the steel ring web material produced by the process adopts near-net-shape rolling, so that no corner waste steel and hollow waste steel are generated, compared with the existing 'whole steel plate blanking' process, the process has the advantages that the yield is at least improved by 40%, the energy is saved, the emission is reduced, the social benefit is obvious, and millions of tons of steel materials are saved every year and the emission of two hundred million tons of standard coal is reduced.
