过去弯管子多半用人工操作,费时很多而质量不高,但是对工人的技术水平却要求很高,所以是目前工厂最头痛的事。为了解决这一问题,我厂采用了如图2所示的弯管装置,弯出来的管子质量很高,能符合加工要求。现在将这种弯管装置介绍如下:这种装置的构造见图2,在平板10的中间,灵活地通过两根滑棒4。在滑棒4的上端车有螺纹,用来固定浮动下型3。在平板10的二旁,各焊有二根撑脚6。在撑脚6的中间,用肖子及螺帽装上翻动型板5,它能绕着肖子的中心旋转。在平板10的中间旋有支撑棒1,在支撑棒1上套
In the past, most of the pipes were manually operated, which took a lot of time and were not of high quality. However, the technical level of the workers was very demanding. Therefore, it is the most troublesome factory. In order to solve this problem, our factory adopts the elbow device as shown in Fig. 2, and the pipe bent out has high quality and can meet the processing requirements. This type of elbow device will now be described as follows. The configuration of this device is shown in FIG. 2, in the middle of the plate 10, it is possible to pass two slide bars 4 flexibly. The upper end of the slide bar 4 has a thread for fixing the floating type 3. On both sides of the flat plate 10, there are two brackets 6 welded. In the middle of the foot 6, flip the flipper 5 with a shank and a nut, which can rotate about the center of the shaw. In the middle of the plate 10 is screwed to the support rod 1, the support rod 1 sleeve
