马蹄形(图1)搬弯工具(图2)由搬弯胎2、3和滚子7等组成,利用两个滚轮之间的槽(图中的B)将钢板旋转滚压成马蹄形。过去我们在制作马蹄形工件时,先用钢板下一块2×200×250(毫米)的料,划好线,再用振动剪剪去外圆及里圆。这样剪成的工件,里圆成锯齿状,变形大,因此,还要经过整形锉修等工序。 Horseshoe (Fig. 1) The bending tool (Fig. 2) consists of a carcass 2, 3 and a roller 7, etc. The plate is rotationally rolled into a horseshoe using a groove between two rollers (B in the figure). In the past when we were making a horseshoe-shaped work piece, we first planted the line with a piece of 2 × 200 × 250 (mm) material under the steel plate and then cut the outer circle and the inner circle with a vibrating shears. This cut into the workpiece, the circle into a jagged, large deformation, therefore, have to go through plastic file repair and other processes.
