在机械制造行业中,一些钢管的切断几乎都是在单头滚刀切管机或多头滚刀切管机上进行的,这种切管法,断面收口严重,毛刺大,需后道工序才能消除。为此,我们利用差速齿轮传动与离心力原理,使切断刀的旋转和进给凸轮的旋转产生较小的相对运动,从而保证了切断刀的旋转(管件夹紧不转)和径向进给这两种速度差别很大的运动在同一个传动系统中得以实现。这种传动原理结构简单,紧凑,工作方便可靠而且规格变换灵活,经使用,能消除收口和毛刺现象。一、结构原理切管机结构原理如图1所示。电动机的转速n_o通过皮带传动使蜗杆轴1转动,通过联轴器34使传动轴31转动,齿轮15(z_1)、齿轮28(z_3)随之转动。此时
In the machinery manufacturing industry, the cutting of some steel pipes is almost always carried out on a single-head cutter pipe cutter or a multi-head cutter pipe cutter. Such pipe cutter method has serious cross-section shut-in and large burr, which requires a later procedure to be eliminated . To this end, we use the principle of differential gear transmission and centrifugal force, so that the rotation of the cutting knife and the feed cam to produce smaller relative movement, thus ensuring the cutting knife rotation (tube clamping does not turn) and radial feed The two very different speeds of movement in the same drive system to be achieved. The principle of this transmission structure is simple, compact, easy to work and reliable and flexible specification changes, by using, can eliminate the mouth and burr phenomenon. First, the structure principle Pipe cutting machine structure shown in Figure 1. Motor speed n_o through the belt drive so that the worm shaft 1 is rotated, the shaft 34 is rotated through the coupling 34, the gear 15 (z_1), the gear 28 (z_3) followed by rotation. at this time
