槽钢的锯削:槽钢的锯削与扁钢一样,要分二次从宽边面往下锯,不能在一个面上往下锯,应尽量做到在长的锯缝口上起锯,工件必须多次改变夹持的位置。
Channelsteel sawing: the channel sawing of the channel steel is the sameas that of the flat steel, but it must be sawed down two times fromthe wide side, and can not be sawed down on one surface, and shouldbe sawed on the long saw mouth as far as so the of theclamping must be changed many times.
日常模具生产中,应注意维护冲切凸、凹模刃口的锋利度。当冲切刃口磨损时,紧固件采购,材料所受拉应力将增大,从而冲压件产生翻料、扭曲的趋向加大。
In dailymold production, attention should be paid to sharpness of punchingand concave die edges. When the cutting edge is worn, the tensilestress of the material will increase, and the stamping and bendingwill increase.
五金冲压件加工包括冲裁、弯曲、拉深、成形、精整等工序。冲压件加工的材料主要是热轧或冷轧(以冷轧为主)的金属板带材料,例如碳钢板、合金钢板、弹簧钢板、镀锌板、镀锡板、不锈钢板、铜及铜合金板、铝及铝合金板等。
stampingprocess includes blanking, bending,紧固件报价, drawing, forming,finishing and other processes. The main materials for stampingparts are hot rolling or cold rolling (cold rolling), such ascarbon steel,紧固件, alloy steel plate, spring steel plate, galvanizedplate, tin plate, stainless steel plate, copper and copper alloyplate, aluminum and aluminum alloy plate.
