水暖管道工程施工中,弯管的方法虽然很多,但都需多道工序,又不易保证抱弯质量。我单位在施工中试制了一种手压简易钢管抱弯器,使用效果很好,现介绍如下。1.构造手压简易钢管抱弯器主要由底座、凹轮、定位凹轮、轮轴,压杆、支架、刻度尺和定位板等组成,见图1。(1)凹轮:用铸铁加工制成,凹轮外缘的半圆凹槽直径应比相应抱弯管径大1毫米左右。不同规格
In the construction of plumbing pipelines, although there are many ways to bend pipes, they all require multiple processes and it is not easy to guarantee the quality of bending. In the construction of our unit, we have trial-produced a hand-pressed and simple steel pipe bender. The use effect is very good. Now it is introduced as follows. 1. The structure of hand pressure simple steel pipe bending device is mainly composed of base, concave wheel, positioning concave wheel, axle, compression rod, bracket, scale and positioning plate, see Figure 1. (1) Concave wheel: made of cast iron, the diameter of the semi-circular groove on the outer edge of the concave wheel should be about 1 mm larger than the diameter of the corresponding bending tube. Different specifications
