Abstract

The invention discloses wear-resistant anti-corrosion parallel bars for sports. The wear-resistant anti-corrosion parallel bars for sports comprise transverse bars, vertical posts and bases, wherein the vertical posts are arranged on the lower sides of the transverse bars and used for supporting the transverse bars, the bases are arranged at the bottom ends of the vertical posts and used for fixing the vertical posts, and the transverse bars, the vertical posts and the bases are made of a same material. The material comprises, by mass, Mg, Mn, Zn, C, Cu, Si, Cr, Ti, S, P, Fe, inert filler, thebalance Al and inevitable impurities. The invention further provides a forming technology of the wear-resistant anti-corrosion parallel bars for sports. The forming technology is simple and easy to implement. The prepared parallel bars are highly resistant to heat, good in size stability, long in service life and low in cost.

Description

technical field [0001] The invention relates to a parallel bar for sports, in particular to a wear-resistant and anti-corrosion sports parallel bar and a forming process thereof. Background technique [0002] Parallel bars are one of the competitive gymnastics events. The metal frame supports two parallel bars made of wood, plastic or synthetic metal. With the continuous improvement of living standards, people's health awareness is also gradually improving. Strengthening outdoor exercise is what people are currently pursuing. Parallel bars are commonly used in sports equipment in people's lives and schools. As a common and convenient fitness equipment, it can exercise arm strength. , and can stretch the body, which is liked by people; [0003] At present, the parallel bars used in people's lives or in schools are easily corroded due to being installed in the open air for a long time, and are easily worn out after frequent use, which greatly reduces their service life. Con...
