Press quenching machine for steel plates

Abstract

A press quenching machine for steel plates includes a press bed structure, a hydraulic cylinder, a drive roller for advancing and stopping the steel plates, a fixed upper pressure head part, a bottom pressure head part movable up and down within the press bed structure, a plurality of upper pressed ribs provided on the upper pressure head part, and a plurality of bottom pressed ribs provided on the bottom pressure head part. The upper pressed ribs are crosswise arranged with the bottom pressed ribs, the upper and bottom pressed ribs have a density distribution according to a position of a special-shape plate for ensuring the flatness of the steel plates after quenching. In the press quenching machine, the transfer time and heat dissipation of the steel plates can be reduced, and no blind areas or soft spots exist. Therefore, the press quenching machine has a high yield and production efficiency.
