TRIMMING DEVICE AND RESIN SHEET FORMING LINE

摘要

PROBLEM TO BE SOLVED: To provide a trimming device maintaining the shape a formed product almost equal by preventing a blanking displacement during blanking the formed product from a resin sheet to maintain the width of a flange part left on the formed product almost equal. SOLUTION: A tapered surface formed on a peripheral side of a flange part S2 is overlapped on a tapered surface formed on a edge part of a recessed part 15a2. The flange part S2 is stored in the recessed part 15a2. The flange part S2 is pressed against a press cutter 15a5. A peripheral surface of a blanking die 15b is slid against the press cutter 15a5. The blanking die 15b is inserted into a blanking hole 15a4. The flange part S2 is cut at a prescribed position. The width of the flange part left on a blanked formed product becomes almost equal, and the shape of the formed product becomes almost equal.
