Title:
MULTI-STATION CONTINUOUS HOT STAMPING PRODUCTION LINE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2017/071294
Kind Code:
A1
Abstract:
A multi-station continuous hot stamping production line, the production line comprising a loading platform (2), a feeding robot (3), a pressure generator set (4, 9, 11), a conveying robot (5), quenching apparatuses (6, 12), a discharging robot (7), and a conveyor belt (8) arranged in sequence; the pressure generator set comprises a heating apparatus, a moulding apparatus, and at least one pressure generator for mounting said moulding apparatus, the heating apparatus being used for heating all or part of a preformed blank (1) to obtain a hot blank, the moulding apparatus being used for stamping and moulding the hot blank and constant pressure shaping, trimming, and punching same to obtain a hot stamped piece. The present production line can continuously implement rapid heating, stamping, constant pressure shaping, trimming, punching, and quenching, increasing heating efficiency, and avoiding a transportation process prior to stamping the hot blank; blanking a steel plate stamping piece at a high temperature avoids the cutting difficulties as a result of producing martensite tissue at room temperature, reducing the blanking force and obtaining a better blanking edge. Also disclosed is a multi-station continuous hot stamping method.
