Abstract
The method is performed by a power press machine composed of a concave die, a convex die with two shoulders and two depressors separately beside the convex die, and includes the steps of: a) placing the high-strength steel (HSS) on the convex die and under the concave die; b) moving the depressors to have two opposite side portions of the HSS clamped between the concave die and the depressors; c) moving the convex die to press the HSS and keeping the side portions immovable; d) forming two steps adjacent to the side portions by the shoulders; and e) cutting off the steps with the side portions.
Claims6
A method for forming a high-strength steel into a C-shape, which is performed by a power press machine composed of a concave die with a concavity and two recesses separately beside the concavity and a convex die with a protrusion and two shoulders corresponding to the two recesses and two depressors separately beside the convex die, the method comprising the steps of:
- a) placing the high-strength steel (HSS) on the protrusion of the convex die and under the concave die;
- b) making two opposite side portions of the HSS clamped between the concave die and the depressors;
- c) making the HSS pressed by the protrusion and keeping the side portions immovable;
- d) forming two step portions separately adjacent to the side portions by the shoulders;
- and
- e) cutting off the step portions with the side portions.
A power press machine comprising:
- a concave die having a concavity and two recesses separately beside the concavity;
- a convex die with a protrusion and two shoulders corresponding to the two recesses and two depressors separately beside the convex die;
- and
- an adjusting mechanism, disposed at an edge of concave die, having an adjustable screw rod and a block for adjusting the step portions between the convex die and the depressor.
