26吋自行车前叉腿电镦热压工艺是一种新的加工工艺,它把原来前叉腿头部的20道加工工序减为8道,用电镦热压成形,大大提高了生产率,并提高产品质量、减轻劳动强度和减少环境污染。其所用装置的示意图见图1。 一、前叉腿电镦工艺过程 前叉腿头部原来的加工工艺为: 加热—缩头—开槽—放铜皮—装接片—钻铆钉孔—铆接—盐浴焊共八道。这里未包括轧锥度等其他加工工序。
The 26-inch bicycle front fork legs electric upsetting process is a new processing technology, which reduces the head of the original fork leg 20 processing steps to 8, the electric upsetting pressure forming, greatly improving productivity and Improve product quality, reduce labor intensity and reduce environmental pollution. The schematic diagram of the device used is shown in Figure 1. First, the fork legs electric upsetting process before the fork leg head of the original processing technology: heating - shrink head - slotting - put copper - mounted pieces - drilling rivet holes - riveting - a total of eight salt bath. This does not include taper and other processing steps.
