Hot clamping method and clamping cooling apparatus

摘要

A hot clamping method includes: blanking to cut a material; cold-working to cool down the cut material to produce a product having a shape of a completed product; heating the cooled product in a heating furnace; and clamping cooling to set the heated product in a clamp to clamp it so that it is in contact with the clamp to be cooled down.

主权项

1. A clamping cooling apparatus, comprising:
a base of the clamping cooling apparatus used in clamp cooling; a first cooling steel that is fixed on the base and has a heated product mounted thereon; a plurality of second cooling steels that move relative to the base so as to make contact with a top of the product mounted on the first cooling steel; and a moving device that moves the plurality of second cooling steels, wherein the clamping cooling apparatus includes: a third cooling steel that is installed on the base and makes contact with the product mounted on the first cooling steel approaching along a side surface of the product; and a slider that has the third cooling steel at an of end of the slider, the slider being supported and slid by a slider support part fixed on the base, and the slider being slid by a hydraulic cylinder, and wherein the moving device includes: a rotation support part formed on the base; and a rotation part that is coupled by a support hinge of the rotation support part, wherein each of the plurality of second cooling steels is fixed on a side of the rotation part closer to a front end of the rotation part with respect to the support hinge, and a second hydraulic cylinder is hinged on another side with respect to the support hinge, wherein the rotation part rotates on the support hinge as the second hydraulic cylinder operates.
