目的研究YN2D-A全自动热丝切割机在低熔点铅档块制作中的应用。方法通过局域网将档块轮廓以数字化文件传至全自动热丝切割机,切割出泡沫阴模后制作铅档块,用模拟定位机对制作好的铅档块进行验证。结果选取本科2008年12月以来制作的783块铅档块在模拟定位机上验证,有616块合格(78.7%);不合格有167块(21.3%)。结论笔者将YN2D-A型全自动热丝切割机应用到低熔点铅档块的制作中,提高了阴模切割的质量,提升了铅档块制作的合格率,取得了较好的效果。 Objective To study the application of YN2D-A automatic hot wire cutting machine in the manufacture of low melting point lead block. Methods The profile of profile was transmitted to automatic hot wire cutting machine through digital file through LAN. The foam block was cut out to make lead block. The simulated lead plate was used to verify the produced lead block. Results A total of 783 pieces of lead blocks were tested on the simulator since December 2008, with 616 pieces (78.7%) and 167 pieces (21.3%) failed. Conclusion The author applies YN2D-A automatic hot wire cutting machine to the manufacture of low melting point lead block, improves the quality of negative block cutting, improves the pass rate of lead block production and achieves good results.
