我厂JX—130汽车大梁展开形状见图1,材料16Mn,厚5毫米。由于没有大型冲压设备,展开下料这一工序以前一直用氧气切割,质量差、效率低。为解决剪切动作由两只等速逆向旋转的直径105毫米的圆刀盘12完成,当工件送进两刀盘之间即被剪切,并被刀盘对工件的摩擦力的水平分力所牵引而连续前进。 I plant JX-130 car beam to expand the shape shown in Figure 1, material 16Mn, thickness 5 mm. Since there is no large-scale stamping equipment, unwinding this process has been cut with oxygen before, poor quality, low efficiency. In order to solve the shearing action, two constant-speed rotating circular cutter disks with a diameter of 105mm are used to complete the shearing action. When the workpieces are fed between the two cutterheads, shearing is performed and the horizontal component of the frictional force of the cutterhead to the workpiece Traction and continuous progress.
