Abstract

The invention discloses an upper roller set bracket positioning and locking device and a roller replacing method. The upper roller set bracket positioning and locking device comprises a rear machine frame; a swing support is hinged into the machine frame through a pin shaft, the tail of a hydraulic cylinder is installed on a machine frame, and the free end on the piston rod side is hinged to the swing support so as to control the swing support to swing up and down in the machine frame; and a locking device is installed on the side, facing the front machine frame, of the upper face of the swing support, and an upper roller set bracket monitoring module is arranged for starting the locking device to lock an upper roller set bracket after monitoring that the upper roller set bracket reaches a preset position. According to the upper roller set bracket positioning and locking device and the technological process, the conception is simple, positioning is accurate, the equipment and the control process are reliable, the automation degree of the technological process is high, and the upper roller set bracket positioning and locking device has the advantages of being low in equipment cost and convenient to overhaul and maintain.

Description

technical field [0001] The invention relates to a positioning and locking device and a roll changing method for an upper roller group bracket of a row straightening machine, in particular to an upper roller group bracket of a high-rigidity small-sized steel row straightening machine with a movable side frame Positioning and locking device and method for changing rollers. Background technique [0002] The device and method for positioning and locking the brackets of the upper roll group belong to the small steel row straightening technology in the field of steel rolling, and are applied to the whole automatic roll changing process of the row leveler. The bracket of the upper roll group cooperates with the automatic roll changer to quickly and integrally replace all the upper and lower straightening rolls. [0003] In the row-by-row straightening machine with mobile frame, the frame on the operating side can be moved; the upper and lower straightening roller systems are beari...
