Claims

[Scope of utility model registration request]

This is a processing device for folding the edge of a workpiece, which includes a support table placed on a lower die base to set the workpiece in a horizontal state, and a support table that folds the edge of the workpiece in conjunction with the lowering movement of the upper die base, which can be raised and lowered. A cam slider that performs continuous processing of first and second pre-processing to bend at a right angle and further inward at a predetermined angle, and hem processing to fold back the edge of the workpiece, and a cam slider that performs continuous processing of the first and second pre-processing to bend the workpiece at a predetermined angle and further inward, and the hem processing for folding the edge of the workpiece. The support table is equipped with a cam guide that guides the machining operation, and the support table is mounted on the fixed table and the edge of the workpiece, and is held at a position separated from the fixed table during the first and second pre-processing, and is held on the fixed table side during hem processing. The cam slider is horizontally suspended and supported by the upper die base via a retainer, and is attached to the retainer so as to be movable toward the workpiece. On the side facing the edge of the workpiece, there is a first pre-cutting blade that bends the edge of the workpiece almost downward at a right angle, a second pre-cutting blade that further bends the edge bent at right angles inward at a predetermined angle, and finally folds back the edge. A hemming processing device characterized by a hemming blade formed continuously.
