Intelligent rolling mill

Abstract

The invention discloses an intelligent rolling mill used for steel rolling equipment. The intelligent rolling mill comprises a first mill roll and a second mill roll which are arranged on a first bearing seat component and a second bearing seat component, a roller spacing adjusting mechanism which is used for adjusting the space between the first bearing seat component and the second bearing seat component, and a mill roll axial adjusting mechanism, wherein one end of a vertical post is connected with a rolling mill stand, and the other end of the vertical post is connected with an upper horizontal beam; the roller spacing adjusting mechanism comprises a hydraulic cylinder and a spring, wherein the hydraulic cylinder is arranged on the upper horizontal beam and pushes downwardly the second bearing beat component, and the spring is supported between the first bearing seat component and the second bearing seat component; a hydraulic motor or a servo motor is selected as the power source of the mill roll axial adjusting mechanism; and a controller outputs a control signal to drive the hydraulic motor or the servo motor to rotate and controls the control loop of the hydraulic cylinder. The rolling mill disclosed by the invention is the intelligent rolling mill formed by assembling separation components, has strong rack rigidity and is beneficial to the roller spacing adjustment and a mill roll axial adjustment.

Description

technical field [0001] The present invention relates to steel rolling equipment, specifically the frame structure of a rolling mill. Background technique [0002] The processing of the centerline bar in the prior art mostly adopts rolling mill to form. The rolling mill can generally be divided into archway-type frame, cantilever-type frame or archway-type frame welded by profiles in terms of its structure. The adjustment and control of the roll spacing directly leads to the size of the product to be rolled, the size of the product to be rolled Dimensional accuracy depends on the overall rigidity of the rolling mill stand and rolls, the accuracy and material selection of the rolls. At present, in rolling mills with archway-type racks and cantilever-type racks, taking the vertical installation of archway-type racks as an example, the deformation in the up and down directions is relatively large and difficult to control, because the lower bearing seats are fixed by bolts. On ...

Problems solved by technology

The defect of this scheme is that: when the screw rod 12 is subjected to tension, its entire rod length range is elongated and deformed, and its rigidity is poor; When the impact load is applied in the direction of the bar, the lower end of the screw rod 12 is compressed and deformed, which causes the displacement of the working positions of the first and second rolls, which seriously affects the rolling accuracy.
