Abstract

The invention discloses a press-fit type steel ring production process. The press-fit type steel ring production process comprises the following steps that raw material steel rolls are sheared into blanking steel rolls required by press-fit type steel ring standard specification utilizing longitudinal shearing strip dividing equipment, the blanking steel rolls are fabricated into pipe-shaped blankparts through a molding process after roll opening and flattening, the pipe-shaped blank parts are conveyed into electric resistance welding equipment, continuous welding is performed, welding seamsare processed and scraped synchronously, and press-fit type steel ring siamesed blank parts are fabricated; fabricated press-fit type steel ring siamesed blank part finished products are cut into single-piece press-fit type single-body blank parts utilizing cutting equipment; finishing is performed on the fabricated press-fit ring single-body blank parts to eliminate stress, and stable machining single-body blank parts are obtained; and the obtained stable machining single-body blank parts are ground to the specified width, and press-fit type steel ring finished products are obtained. By meansof the press-fit type steel ring production process, the cost is lowered, the whole production process has less process nodes, less labour is used, the consistency and stability of the welding seamsare high, and the single-piece good product rate of the machined steel rings is greatly increased.

Description

technical field [0001] The invention relates to a press-fit solid tire fitting, in particular to a production process of a steel ring. Background technique [0002] Press-fit solid tires (GB / T16623-2008) are mainly used as driving wheels and driven wheels in low-speed and heavy-duty engineering equipment and mine terminal equipment. The main consumer market is in foreign markets with developed mining industry and well-developed circulation. The main manufacturers of press-fit solid tires are also several large tire rubber manufacturers in the world, distributed in Sri Lanka, the United States, Canada, etc. China is not a major producer of press-fit solid tires. Domestically produced press-fit steel rims are mainly produced by several large-scale press-fit solid tire manufacturers abroad. [0003] Due to the vigorous development of the manufacturing industry after China's reform and opening up, China's raw materials have a strong price competitive advantage in the world unde...
