Forced cooling device of round piece

Abstract

The invention belongs to a device for carrying out the forced cooling of round workpieces, mainly longer pipe workpieces and bar workpieces, under the condition of a high temperature, relates to a forced cooling device of the round workpieces and overcomes the disadvantages that the required cooling bed is comparatively long, and the construction cost of equipment and factory buildings is increased in the prior device. The device comprises a programmable logic controller, a lifting roll table mechanism and a cooling table mechanism arranged at intervals in a line, a cooling water spraying device, a protective cover, etc., wherein the cooling table is composed of a first-group carrier roller (12) and a second-group carrier roller (13) which are arranged side by side on the cooling table; the rotation control of the two carrier rollers is realized by the programmable logic controller through controlling a drive motor (1); and a hydraulic cylinder or an air cylinder is controlled by the programmable logic controller to drive a front connecting rod (8), a rear connecting rod (9) and a connecting block (3) so as to allow a lifting roll table (6) to swing and lift around a swing arm shaft of the lifting roll table. The device is suitable for the rapid forced cooling of the heavy section steel tubes and the bar workpieces.

Description

Technical field: [0001] The invention relates to a cooling device, in particular to a device for forced cooling of a circular workpiece (such as a hot-rolled seamless steel pipe or bar) under high temperature. Background technique: [0002] At present, in the rolling production equipment of seamless steel pipes or bars in metallurgical enterprises, the hot-rolled pipes and rods need to be cooled by air on the cooling bed before entering the next process, but for some thick-walled steel pipes, especially extra-thick-walled For steel pipes or rods, cooling with existing equipment requires a longer cooling bed, which increases the cost of equipment and workshops. At the same time, the long cooling time also prolongs the production cycle of pipes and rods. The production efficiency is greatly reduced. Invention content: [0003] The present invention solves the problems that existing equipment needs to have a longer length of cooling bed when cooling pipes and rods in a high ...
