本厂工具科业余小工厂的全体职工,发揮了集体的智慧,用土法試制成功一种拔管机,并获得了初步的效果。机器构造:这架机器的結构很簡单,如图1所示,一部电动机和两块槽型鋼架、四个齿輪进行变速外,再就是用一根环鏈。軸承等用螺絲联接,其他部分都用电焊联接;另外再做一个簡单的拔管钩卡(如图2),便可以进行拔管。操作方法:用3公厘普通鋼板,寬度按1 1/2″鋼管的直径展开寬度計算;也就是說:1 1/2″
Our factory staff Yuyi small factory all employees, played a collective wisdom, trial success with soil a kind of tube pulling machine, and obtained initial results. Machine structure: The structure of this machine is very simple, as shown in Figure 1, a motor and two slotted steel frame, four gears for speed change, then there is a chain. Bearings and other connections with screws, the other parts are welded together; the other to do a simple pulling hook card (Figure 2), they can be extubated. Method of operation: with 3 mm ordinary steel, the width of the width of 1 1/2 “pipe diameter; that is: 1 1/2”
