等が発生する不具合が生じていた。(Prior art) Generally, burrs on thin plate pressed products are cut and removed by a trimming press die, but at that time,
It is necessary to remove burrs so as not to damage the shape of the part, and in pressed products such as automobile frames and sand sills that are formed by deep drawing or bending and have a nearly vertical shape and a high part, it is necessary to remove burrs. This is cut by a trimming press die, that is, an upper die and a lower die each having a cutting edge that follows the shape of the thin plate press product at the edge portion,
The cutting thickness of the vertical part is substantially different from that of the almost horizontal part other than the vertical part in relation to the stroke of the upper mold, and this causes problems such as wrinkles, etc., on the cut surface of the vertical part. was.
