HOT-STAMPED TRIM COMPONENT - TOYOTA TEKKO KK

Title:

HOT-STAMPED TRIM COMPONENT

Document Type and Number:

WIPO Patent Application WO/2016/084684

Kind Code:

A1

Abstract:

In order to improve the productivity of a hot-stamped trim component which is moulded by hot press processing and from which an outer peripheral surplus section is thereafter cut away by laser processing, the outer peripheral shape includes a laser trim line (L1) and a press trim line (L2). Therefore, a required minimum range such as a site or the like that requires post-processing due to the occurrence, for example, of burrs or the like may be cut away by laser processing, the processing cost and processing time are reduced, and productivity is improved. Furthermore, the laser trim line (L1) and the press trim line (L2) are connected via a protruding-shape corner section (30), and the shape of the connected portion is therefore stabilised regardless of relative positional shifts, caused by processing errors, of both lines. Processing quality variations due to steps, protrusions, or the like, caused by processing errors are suppressed by comparing the trim lines (L1) and (L2) when connected smoothly on a straight line.
