由于我厂去年生产1米以上的金属支柱新产品,急需一台剪6号角钢的剪板机。如果请上海生产厂家特制一台,需花二万多元的资金,并且临时设计、制造时间又长,无法投入使用,真是远水救不了近火。因此,我们对Q11—13×2500型剪板机的压板(横梁压紧)部份进行了改造。首先把压紧弹簧圈,通过计算,由原来的有效圈数n_1=12,改为n_1=9,总圈数n=13.5,改为n=10.5,金属丝的展开长度为L=5610,改为L=4370。把压紧托脚进行了改造,这样解决了提升高度,并且不撞弹簧套筒。然后把垫块,加高加大,同时解
As I plant last year to produce more than 1 meter of metal pillar of new products, an urgent need to cut a 6 angle plate shears. If you ask a Shanghai manufacturer made a special need to spend more than 20,000 yuan of funds, and temporary design, manufacturing time is long, can not be put into use, really far water can not save near fire. Therefore, we Q11-13 × 2500 shears plate (beam compression) part of the transformation. First, the compression spring was calculated from the original effective number of turns n_1 = 12 to n_1 = 9, the total number of turns n = 13.5, to n = 10.5, the wire length of the expansion of L = 5610, change For L = 4370. The compacted leg has been modified, thus solving the lifting height, and does not hit the spring sleeve. Then the pad, increase higher, at the same time solution
