过去风割铆钉的方法,是从铆钉体平头的一端,沿外缘一圈一圈地向内旋转熔割,直到平头的埋头部分完全熔去,再用冲头将铆钉冲下。采用这一种方法,每人每天只能熔割铆钉300只左右,效率很低。上海船舶修造厂胡金良同志采用了先进的快速风割法,一天就能俯割φ7/8″铆钉1026只,提高了工作效率达两倍半以上,并且节省了氧气和乙炔气40%。
In the past wind cutting rivets method is from the flat end of the rivet body, along the outer edge of the circle around the spin-melting until the head of the buried part completely melted, and then the rivet punching down. Using this method, each person can only melt around 300 rivets a day, the efficiency is very low. Shanghai Ship Repair Factory Comrade Hu Jinliang adopted the advanced method of rapid wind cutting, which can take down 1026 φ7 / 8 "rivets in a single day, improving work efficiency by more than two and a half times and saving 40% of oxygen and acetylene gas.
