为了加工ZW950型振动流动干燥机上的复合弹簧,必须加工内部结构和要求如图1所示的模具。由于型腔复杂,螺距大,用普通车床加工难度较大。我厂研制的大螺距螺旋槽加工刀具,在CA6250普通车床上使用,解决了这一工艺难题,产品满足了设计要求。刀具结构见图2,它由刀杆体1、浮动定位块2、滑块3、刀杆4、车刀5等组成。浮动定位块2可在滑块3内自由滑动,刀杆4可在刀杆体1内伸缩,车刀5可根
In order to process ZW950 vibration flow dryer compound spring, you must process the internal structure and requirements of the mold shown in Figure 1. Due to the complicated cavity and large pitch, it is difficult to process with ordinary lathe. I plant developed large pitch spiral groove machining tools, used in CA6250 ordinary lathe to solve this process problems, the product meets the design requirements. Tool structure shown in Figure 2, which consists of a knife rod body 1, floating positioning block 2, slider 3, Arbor 4, turning 5 and other components. Floating positioning block 2 can slide freely within the slider 3, the arbor 4 can be retracted telescoping knife body 1, the turning tool 5 can be root
