自動滾螺紋机普通祇能滾製“六角”、‘方头’、‘圆头机器’及‘平头机器’等螺絲,对於其他特种形式而带有螺紋的零件(图一),則無法滾制。為了能充分利用滾紋机的高度生產率,使滾纹机也能滾制特种螺絲,經过了多次試验,我們制成了一种夾具,將此夾具裝在螺紋机上,就能進行滾製各种带有螺紋的零件。伹在利用此夾具進行滾製特种螺絲時,不能应用該机的自動進料装置,須用人工送料,此是其唯一缺點。
Automatic thread rolling machine can only roll ordinary “hex”, square head, round head machine and flat head machine screws, for other special forms with threaded parts (Figure 1), you can not roll system. In order to take full advantage of the high productivity of the rolling machine, the roller can also roll special screws, after many tests, we made a fixture, the fixture installed in the thread machine, you can roll Various threaded parts.伹 In the use of this fixture for rolling special screws, the machine can not be applied to the automatic feeding device, the need to manually feed, this is its only drawback.
