电动煨管机是我施工队水暖班的工人同志和技术员在文化大革命的高潮中制成的。几年来,对胜利完成施工任务,做出了积极贡献(见图1、图2)。电动煨管机(见图3)以一台2.8瓩四极电动机为动力,经过皮带轮、齿轮和一组蜗轮蜗杆变速为每分钟一转。蜗轮主轴带动工作转盘,连同附设的芯杆支架、滑板以及与煨制管径相配合的一组模胎、芯子组成机器。工作时先在工作转盘上装好相应的圆胎,并 Electric boring machines were made by the comrades and technicians of the construction team plumbing class during the climax of the Cultural Revolution. Over the past few years, he has made positive contributions to the successful completion of construction tasks (see Figure 1 and Figure 2). The electric tube machine (see Fig. 3) is powered by a 2.8-inch four-pole motor and is shifted to one revolution per minute via pulleys, gears and a set of worm gears. The worm gear spindle drives the working turntable, together with the attached core bar bracket, slide plate, and a set of die tires and core sub-machines matched with the caliber pipe diameter. When working, first install a corresponding round tire on the working turntable, and
