与传统的冷流道模具相比,热流道模具具有节约原料、提高生产效率等优点而被广泛采用。在热流道模具体统中,其中的喷嘴、加热器等都为圆柱状,在大批量生产时,需在数控车床上进行大量的圆柱类零件的切削加工。而现有的常规加工方式,通常是把切成规格长度的钢棒先通过手持固定到车床的三爪卡盘上,再操作刀架拖板到加工位置进行切削加工。整个过程中,对等加工的钢棒进行夹持占用了大量的时间,同时,通过手持固定也使得钢棒的轴线与车床主轴轴线的重合形较差,钢棒需留有较大的切削余量,本文针对上述问题阐述一种辅助装置的设计方案。
Compared with the traditional cold runner mold, hot runner mold has the advantages of saving raw materials and improving production efficiency and has been widely used. In the hot runner mold system, one of the nozzles, heaters, etc. are cylindrical, in mass production, the need for CNC lathes for a large number of cylindrical parts of the cutting process. The existing conventional processing methods, usually cut into the length of the steel rod first fixed to the lathe by hand on the three-jaw chuck, and then manipulate the carriage to the processing position for cutting. The entire process, the equal processing of steel holding takes a lot of time, at the same time, by hand holding also makes the axis of the steel spindle and the spindle coincides with poor shape, the steel rod to leave a larger margin Volume, this article addresses the above issues described an auxiliary device design.
