我们车间加工图(a)所示型板上的型腔(未画出)花纹时,遇到下列问题;①铁屑常常挡住操作者的视线,必须干一下停一下,以便扫除铁屑,因此生产率极低;②加工中部型腔时,为了看清加工线,工人必须弯腰操作,很容易疲劳。我们曾设专人扫铁屑,用压缩空气吹铁屑,但均不理想。因为,前者要多占用一人,后者噪声大,也不安全。现在用简易仿线加工法,较合理地解决了上述问题。图(b)为简易仿线加工法的示意图,在仿线铁上划出与型腔一致的加工线,加工时将其放在工人能看清的部位上,并使其与工件型腔的加工线平行。然后在铣头或床身立导轨 The following problems were encountered when machining the pattern of the cavity (not shown) on the pattern shown in Figure (a) in our workshop. ① The iron filings often obscured the operator’s line of sight and must be stopped for a second to remove iron filings Low productivity; ② processing the central cavity, in order to see the processing line, workers must bend over the operation, it is easy to fatigue. We have set up special staff to remove iron filings and use compressed air to blow iron filings, but none of them is satisfactory. Because the former occupies more than one person, the latter is noisy and unsafe. Now with a simple line processing method, a more reasonable solution to the above problems. Figure (b) Schematic diagram of a simple imitation line processing method, in the imitation iron line and draw the cavity consistent with the processing line, the processing will be placed on the workers can see the site, and make it with the workpiece cavity Processing line parallel. Then in the milling head or bed rails
