判別鑄鐵平板平面的形狀方法
鑄鐵(tie)平(ping)板(ban)平(ping)面(mian)幾(ji)何(he)形狀(zhuang)有三(san)種，凸面(mian)、凹面(mian)和(he)鞍面(mian)。鑄鐵(tie)平(ping)板(ban)平(ping)面(mian)形狀(zhuang)是根據平(ping)面(mian)度的數值來(lai)差別的，其方法如下。

在大約(yue)兩對角線和垂直(zhi)線的截(jie)(jie)(jie)面(mian)(mian)(mian)(mian)(mian)上，分別找(zhao)出2-3條有共(gong)點的截(jie)(jie)(jie)面(mian)(mian)(mian)(mian)(mian)，把這幾(ji)(ji)條截(jie)(jie)(jie)面(mian)(mian)(mian)(mian)(mian)的直(zhi)線度數據標(biao)(biao)注在直(zhi)角坐標(biao)(biao)上。X坐標(biao)(biao)為(wei)間距(ju)，Z坐標(biao)(biao)為(wei)直(zhi)線度數據。鑄鐵(tie)平(ping)板平(ping)面(mian)(mian)(mian)(mian)(mian)的幾(ji)(ji)何形(xing)狀(zhuang)按這幾(ji)(ji)條截(jie)(jie)(jie)面(mian)(mian)(mian)(mian)(mian)的形(xing)狀(zhuang)判別，如截(jie)(jie)(jie)面(mian)(mian)(mian)(mian)(mian)都是凸形(xing)，那(nei)么平(ping)面(mian)(mian)(mian)(mian)(mian)為(wei)凸面(mian)(mian)(mian)(mian)(mian)；反之為(wei)凹(ao)面(mian)(mian)(mian)(mian)(mian)。如有的截(jie)(jie)(jie)面(mian)(mian)(mian)(mian)(mian)呈凸形(xing)，有的截(jie)(jie)(jie)面(mian)(mian)(mian)(mian)(mian)呈凹(ao)形(xing)，那(nei)么平(ping)面(mian)(mian)(mian)(mian)(mian)為(wei)鞍面(mian)(mian)(mian)(mian)(mian)。訂購鑄鐵(tie)平(ping)板泊頭市(shi)正創(chuang)機械設備制造有限(xian)公司(si)0317-8380005
