Abstract

The invention provides a top clamping spraying cooling device. The device comprises a clamping assembly and a spraying cooling assembly. The clamping assembly comprises paired clamping mechanisms which are symmetrically arranged about the axis of a clamped top. Each clamping assembly comprises a clamping claw, a rotating arm with the first end hinged to the clamping claw and a driving part with the telescopic movement end hinged to the second end of the rotating arm. Each clamping mechanism further comprises a rotating arm seat, wherein the third end of the rotating arm is hinged to the rotating arm seat. The paired clamping claws are converted between the clamping state that the top is clamped and the releasing state that clamping of the top is released under the drive of the respective rotating arms under the telescopic effect of the driving ends of the respective driving parts. By means of the top clamping spraying cooling device, three processes of top disengaging, top clamping and spraying cooling can be synchronously conducted at the same station and are seamlessly connected with the previous and posterior production work processes, and waste of invalid action time is avoided; and the production time of steel pipes is saved, and the production efficiency is improved.

Description

technical field

[0001] The invention relates to steel rolling technology, in particular to a plug clamping spray cooling device. Background technique

[0002] In the piercing and rolling or rotary expansion process of the seamless steel pipe production line, there is a production process: after the piercing and rolling of the ejector rod with the plug is completed, the plug leaves the piercing and rolling host with the ejector rod. At this time, the ejector rod and the plug need to be temporarily separated. The plug stays at one station, and the ejector rod enters the next station with the pierced and rolled capillary. At this time, the plug is moved into the cooling system, and the cooling process of the plug is carried out. Return the ejector pin that has been separated from the capillary to the combined station with the plug. Because the clamping release and cooling of the plug are two stations and two processes, it takes time to move. At the same time, before the top o...
