针对传统手工弯管器的缺点,我们作了大胆改进,采用“折叠式手柄及挂钩平衡”的方法,制成一种新式手工弯管器。在一推一扳的过程中即可完成对管件的弯曲、装卸,弯管工效提高3倍多。 弯管器的结构如图1所示。它由定轮模2、定心轴4、折叠手柄轴6、折叠式手柄9、滚轮模10、挂钩12、圆管偏心压把14和限位块15 In response to the shortcomings of the traditional manual pipe bender, we made a bold improvement, using the “folding handle and hook balance” method, made of a new type of manual pipe bender. In the process of pushing a pull can be completed on the pipe bending, loading and unloading, bending more than 3 times the work efficiency. Tube structure shown in Figure 1. It consists of fixed wheel mold 2, centering shaft 4, folding handle shaft 6, folding handle 9, roller mold 10, the hook 12, the cylinder eccentric pressure 14 and the stopper 15
