制造厂在生产溴化锂制冷机的过程中,都会遇到如图1所示的管板零件上大量的小孔中带二条环形槽的加工问题。一般厂家都无专用加工设备。为解决在普通机床上完成胀管孔的加工,我厂在参考了有关资料和经过了多次改进和试验后,自制成功了一种能在Z3040普通摇臂钻床上使用的小孔内环槽钻具。使用它能十分方便地一次性加工出符合要求的小孔中的二条环形槽。经过我厂多年使用,实践证明是成功的,它很适合一般中小型溴化锂制冷机制造厂使用。现介绍如下:
Manufacturers in the production of lithium bromide refrigerator process, will encounter the tube plate parts shown in Figure 1 a large number of holes with two annular groove processing problems. General manufacturers have no special processing equipment. In order to solve the processing on the common machine tool to complete the expansion of the hole, I plant in the reference to the relevant information and after many improvements and tests, the homemade success of a Z3040 ordinary radial drilling machine used on the inner ring groove Drilling tools. With it, it is easy to work out the two annular grooves in the required holes in one go. After years of my factory use, the practice proved to be successful, it is suitable for general small and medium-sized lithium bromide refrigerator manufacturer. Now introduced as follows:
