A vertical small diameter work roll ring rolling device

Abstract

The invention discloses a vertical small-roller-diameter working roller ring rolling device and belongs to the technical field of ring piece rolling equipment. The vertical smaller-roller-diameter working roller ring rolling device solves the technical problems that the contact area of a working roller and a to-be-rolled ring piece is large, and the required equipment rolling force is large. The device comprises a roller frame, an upper roller system and a lower roller system. The roller frame comprises a main frame and an auxiliary frame. The main frame and the auxiliary frame are oppositelyarranged. Upper roller sliding blocks are correspondingly arranged in the main frame and the auxiliary frame. Lower roller sliding blocks are arranged below the upper roller sliding blocks in the mainframe. Lower roller fixing seats are arranged below the upper roller sliding blocks in the auxiliary frame. A hydraulic cylinder drives the upper roller sliding blocks to slide up and down along guide pillars. The upper roller system comprises an upper support roller, an upper transmission roller and an upper working roller, wherein the lower roller system and the upper roller system are symmetrically arranged with respect to the center line in the rolling roller seam, and the lower roller system is sleeved with the to-be-rolled ring piece. According to the vertical small-roller-diameter working roller ring rolling device, the small-roller-diameter working roller enables the local deformation area to be reduced, the rolling pressure and torque transmission of the working roller are guaranteed by the multi-roller train transmission system, and the service life of the roller is prolonged.

Description

technical field [0001] The invention belongs to the technical field of ring rolling equipment, and in particular relates to a vertical small diameter work roll ring rolling device. Background technique [0002] Ring rolling (also known as ring rolling, ring rolling, hole reaming, and ring rolling) is carried out by means of two work rolls, the driving roll and the core roll of the ring rolling machine (also known as ring rolling machine, ring rolling machine, and hole reaming machine). The role of the ring produces continuous local plastic deformation, and then realizes the plastic processing technology of reducing the wall thickness, expanding the diameter and forming the cross-sectional profile. [0003] During the rolling process, the two work rolls are in contact with the inner and outer surfaces of the ring to be rolled (rolled). The larger the contact area, the better the forgeability of the ring. However, if the contact area is too large, the required rolling force wi...
