Abstract

The utility model belongs to a device for forcedly cooling a round workpiece in a high-temperature state and mainly for cooling a tube or a rod, relates to a forced cooling device for the round workpiece, and solves the problems of the increase of the manufacturing cost of devices and workshop buildings due to a longer required cooling bed in the prior art. The device comprises a programmable controller, a mill table mechanism and a cooling workbench arranged in a row and spaced at an interval, a cooling water spray device, a protective cover and the like. A first set of rotary support rollers and a second set of rotary support rollers are disposed in parallel to each other and on the cooling workbench. The programmable controller implements the rotation control to the two support rollers by controlling a driving motor (1), and controls a hydraulic cylinder or a cylinder to allow the mill table (6) to swing and lift around the axis of the swing arm of the mill table by pushing a front connection rod (8), a rear connection rod (9) and a connection block (3). The device is suitable for rapidly and forcedly cooling steel pipes and rods with thick walls.
