Abstract
PURPOSE: To enable rounding to be performed without giving any flaws to a steel pipe by placing half-split pipe made of PVC on the steel plate placed on a V-form or concave die thereby pressing the steel plate with a punch by way of the V-form backing plate on the inner side of the pipe.
CONSTITUTION: A PVC steel plate 5 being the work is placed with its surface being faced downward, on the top of a die 4 formed with V-form or concave groove. Next, a half-split pipe 7 comprising cutting a PVC pipe of the same length as the bending width of the PVC steel plate 5 in its longitudinal direction is placed. Next, a bending plate comprising horizontally fitting a steel plate 8 so as to form a suitable bridge to the inner side of the half-split pipe 7 is placed. Then, the work is pressed by a punch 1 from above the steel plate 8 and is thereby bent to the radius proportional to the outside diameter of the half-split pipe 7.
