北京怎样的冲孔板才是冲孔网的最佳选择材料

作者:【admin】 来源:【原创】 发表时间:【2016-04-22 16:30:46】 浏览:【次】


  冲孔网从进料到加工再到成品,每一步的工序都很重要,但是冲孔网成品的好坏也取绝于冲孔板的质量,但是怎样的冲孔板才能是冲孔网的最佳选择材料呢?红升冲孔网厂为大家分析一下:

  一、良好的冲压性能  冲孔板冲压性能是指板料对各种冲压加工方法的适应能力。冲压加工方法是以金属为塑性的加工方法,因此,要求材料具有良好的塑性。对于塑性好、要求允许的变形程度大的材料,则可以减少筛板冲压工序次数及中间退火次数。对于分离工序也要求具有一定的塑性,同时要求材料的屈服极限稍高一些,以利于冲裁后获得较高的断面质量。

  二、良好的表面质量  表面质量好的材料,筛板冲压时工件不易破裂,废品减少;模具不易擦伤,寿命提高,而且制件的表面质量好。所以,一般要求冲压材料表面光洁、乎整,无氧化皮、裂纹、锈斑、划痕等缺陷。

  三、符合国标规定的厚度公差  模具间隙是按材料厚度来确定的,所以,材料厚度公差应符合国家规定的标准。否则,厚度公差太大,将影响工件质量,并可能导致损坏模具和设备。
