Pressure quenching mold for obtaining quality-controllable intensified heat-treated superhigh intensity steel plate

Abstract

A pressure quenching mold for obtaining a quality-controllable intensified heat-treated superhigh intensity steel plate belongs to the technical field of heat treatment. The mold comprises an upper mold and a lower mold, wherein the lower mold consists of a lower platform, a lower mold mounting plate, a lower vertical rib plate, a lower mold water inlet pipe and a water tank; the lower vertical rib plate, the lower mold water inlet pipe and the water tank are arranged on the lower mold mounting plate, and then the lower mold mounting plate is fixed on the lower platform through a fastening screw; the upper mold consists of an upper platform, an upper mold mounting plate, an upper vertical rib plate and an upper mold water inlet pipe; and the upper vertical rib plate and the upper mold water inlet pipe are arranged on the upper mold mounting plate, and then the upper mold mounting plate is fixed on the upper platform through the fastening screw. When pressure quenching operation is performed, a slide block on a pressure machine moves downwards to drive the upper mold to be enclosed with the lower mold, and cooling water sprayed from the lower mold water inlet pipe and the upper mold water inlet pipe circularly flows in a water passage to perform pressure quenching on the steel plate. The water tank reclaims the sprayed cooling water for later cycle use. The mold has the advantage that: the intensified heat-treated superhigh intensity steel plate produced by the mold has controllable quality and excellent performance.
