Abstract
PURPOSE: To reduce the working time and the working cost for manufacturing titled frame, by bending the blank into a square, by welding the seam, and by reforming the L and the step after deburring from the weld zone.
CONSTITUTION: First of all, the blank 10 is bent 11 into a square form, and under this condition, the welding 12 and the deburring 13 are performed. In the following process, the reformation of the L and the step is carried out simultaneously. In this method, the welding 12 and the deburring 13 become possible under the flat condition, so that the working cost is greatly reduced. Further, since the reformation for the L and the step can be performed at one process, the reduction of working cost at this point can be expected.
