2、針(zhen)對槽鋼剪(jian)(jian)(jian)(jian)刃(ren)設計(ji)存在(zai)的(de)問題(ti)，結(jie)合生產實際情況，將(jiang)剪(jian)(jian)(jian)(jian)刃(ren)設計(ji)為圖2所示的(de)形狀(以100#槽鋼為例)。上(shang)剪(jian)(jian)(jian)(jian)刃(ren)寬度(du)由100mm改(gai)(gai)(gai)為99mm，減少(shao)上(shang)剪(jian)(jian)(jian)(jian)刃(ren)在(zai)左右方(fang)向的(de)間隙，改(gai)(gai)(gai)善槽鋼兩角部的(de)剪(jian)(jian)(jian)(jian)切(qie)(qie)(qie)質(zhi)(zhi)量(liang)(liang)(liang)(liang);下(xia)剪(jian)(jian)(jian)(jian)刃(ren)兩角部圓弧(hu)尺寸由R8mm改(gai)(gai)(gai)為R7mm，提高兩角部的(de)剪(jian)(jian)(jian)(jian)切(qie)(qie)(qie)重疊量(liang)(liang)(liang)(liang)，改(gai)(gai)(gai)善槽鋼肩部剪(jian)(jian)(jian)(jian)切(qie)(qie)(qie)質(zhi)(zhi)量(liang)(liang)(liang)(liang);下(xia)剪(jian)(jian)(jian)(jian)刃(ren)上(shang)邊寬度(du)由79mm改(gai)(gai)(gai)為80mm，下(xia)邊寬度(du)由97mm改(gai)(gai)(gai)為94mm，使下(xia)剪(jian)(jian)(jian)(jian)刃(ren)腿端斜度(du)小(xiao)于槽鋼成品孔型斜度(du)，這樣在(zai)腿部剪(jian)(jian)(jian)(jian)切(qie)(qie)(qie)時，腿部上(shang)、下(xia)方(fang)向上(shang)不會同時受力(li)，從而減少(shao)剪(jian)(jian)(jian)(jian)切(qie)(qie)(qie)力(li)，改(gai)(gai)(gai)善剪(jian)(jian)(jian)(jian)切(qie)(qie)(qie)質(zhi)(zhi)量(liang)(liang)(liang)(liang)。
