我矿深孔钻机钎杆联接部位的螺纹,去为车制加工,现改为压模加工。 一、工作原理(见附图): 将上压模1、下压模4固定在锻钎机上,将烧红的钎杆放于A、B和C、D两个模锻孔内,锻钎机施压力于上压模1上,使上、下压模合拢,将钎杆锻成波浪形螺纹,然后将压力去掉,则上模1被压缩弹簧2顶起(3为导向轴,使上压模1沿此轴移动),取出钎杆,即为成品。
I mine deep hole drilling machine drill rod coupling thread, go to the car system processing, now changed to die processing. First, the working principle (see attached): The upper die 1, the lower die 4 is fixed on the forging machine, the red rod burned into A, B and C, D two forging holes, forging drill The machine pressure on the mold 1, the upper and lower mold closed together, the wedge into a wavy thread, and then remove the pressure, then the top mold 1 is pressed from the top 2 (3 is the guide shaft so that the upper Stamper 1 move along this axis), remove the drill rod, that is finished.
