Fixing device for winding head of rolling mill

Abstract

The invention relates to a fixing device for a winding head of a rolling mill, comprising a base, wherein two mutually-parallel plate frames are arrange on the base. The fixing device is structurally characterized in that fixing stop blocks and moving stop blocks are respectively arranged on the upper sides of the two plate frames; the fixed stop blocks on the two plate frames respectively correspond to each other; and the moving stop blocks of the two plate frames respectively correspond to each other. A space is reserved between the fixed stop block and the moving stop block on the same plate frame; the lower side of each fixed stop block is fixedly connected with the upper side of the corresponding plate frame; the bottom of each moving stop block is hinged to the upper side of the corresponding plate frame; and adjacent surfaces of the fixed stop blocks and the moving stop blocks are respectively concave cambered surfaces. Hydraulic cylinders are arranged outside the moving stop blocks; one end of each hydraulic cylinder is hinged to the upper end of each moving stop block; and the other end of each hydraulic cylinder is hinged to the upper side of the plate frame outside eachmoving stop block. By adopting the fixing device, the winding head can be quickly replaced and high work efficiency is achieved. The fixing device is suitable for quickly replacing the winding head of the rolling mill.

Description

technical field [0001] The invention relates to a fixing mechanism. Specifically, it is a fixing device that facilitates the replacement of the coil head of the rolling mill. Background technique [0002] It is known in the rolling mill manufacturing industry that when the strip on the coil head is full, it is necessary to remove the full volume coil head from the fixture and replace it with an empty coil head. Therefore, the coil heads need to be replaced frequently during the strip rolling process. The traditional fixing device includes a base, on which there are two plates parallel to each other, and semi-arc pin seats are fixed on the corresponding positions on the upper sides of the two plates, and the shafts at both ends of the roll head are respectively placed on the corresponding semi-arc pin seats by means of bearings. Inside, and with the help of bolts, the two semi-arc pressure plate mouths are respectively attached to the corresponding semi-arc pin seats. When...

AI Technical Summary

Problems solved by technology

When replacing the roll head, it is necessary to loosen the bolt and remove the semi-arc pressure plate with the help of tools such as a wrench, so that the roll head can be removed, which makes the speed of changing the roll head slow and the work efficiency is low
