Horizontal four-roller part rolling mill

Abstract

The invention discloses a horizontal four-roller part rolling mill, and belongs to the technical field of metal calendaring and processing. The horizontal four-roller part rolling mill comprises a fixed base, two groups of guide rails, a movable base, a horizontal movable oil cylinder, an inner milling roller motor, two balance oil cylinders, two locking oil cylinders, a fixed bracket, an inner milling roller, an inner supporting roller, a milling roller rack, two cylindrical rollers, an outer milling roller and an outer supporting roller, wherein when the horizontal movable oil cylinder extends out, the movable base is driven to move; the inner supporting roller, the inner milling roller, the outer milling roller and the outer supporting roller are sequentially arranged from top to bottom; a center line of the inner supporting roller, a center line of the inner milling roller, a center line of the outer milling roller and a center line of the outer supporting roller are positioned onthe same vertical plane; the inner supporting roller supports the inner milling roller; the outer supporting roller supports the outer milling roller; and an adjustable distance is set between the inner milling roller and the outer milling roller. The horizontal four-roller part rolling mill is used for processing and manufacturing barrel parts with diameters of 5-15 meters and axial length not smaller than 5 meters.

Description

technical field [0001] The invention belongs to the technical field of metal calendering processing, and relates to processing equipment for metal seamless tubes (with a diameter of 5 meters to 15 meters and an axial length of not less than 5 meters), in particular to a horizontal four-roller tube rolling mill. Background technique [0002] With the development of my country's economy, seamless tubes of various sizes and specifications are more and more widely used in the industrial field, and the production of tubes with a diameter of 5 meters to 15 meters and an axial length of not less than 5 meters, the original Processing equipment can no longer meet the requirements. [0003] Traditional cylinder processing methods: 1) Forging a hollow forging with a solid steel ingot, and then machining it into shape, the cost is high. 2) Rolling machine: use the rolling machine to roll the hollow parts, the diameter of the product can reach 11 meters, but the axial length is within 2...
