我厂生产的QY250-13/32型矿用掩护支架机座,是用16Mn钢板拼焊而成的。其中机座的主立筋板为切割件,厚度为30毫米,形状如图1所示。开始下料时,我们是把零件样板固定在切割机型臂上,由于型臂只能随轴转动,故钢板位置得随样板挪动才能进行下料(板料规格为9000×1800×30毫米)。每切割一块后,须用吊车起吊调整方向,然后靠人工用撬杠挪动。劳动强度大,工作效率低,每班只能切割6～7块。为解决上述问题,我们试制了仿形切割机样板转
My factory production QY250-13 / 32 mining shield bracket base is welded with 16Mn steel. Among them, the main rib of the base is a cutting piece with a thickness of 30 mm, and the shape is shown in FIG. 1. At the beginning of the blanking, we fixed the part model to the cutting arm of the cutting machine. Since the arm can only rotate with the shaft, the position of the steel plate can be moved with the sample plate (the sheet size is 9000 × 1800 × 30 mm) . After cutting a piece, it is necessary to use a crane to adjust the direction of lifting, and then use artificial crowbar to move. Labor intensity, low efficiency, each class can only cut 6 to 7. In order to solve the above problems, we trial prototype copying machine turned
