A kind of vertical rolling machine and rolling method

Abstract

The invention provides a vertical rolling expansion machine, which comprises a machine frame, wherein the machine frame is of a four-upright-post framework type structure; a moving beam, a core roller, a centering roller, a main transmission device and a measuring device are arranged on the machine frame; the vertical rolling expansion machine also comprises hydraulic, electric control, lubricating and cooling systems; and a ring element or a tubular element to be subjected to rolling expansion is put onto the core roller to be subjected to automatic rolling expansion forming. The invention also provides a rolling expansion method of the vertical rolling expansion machine. According to the machine frame of the vertical rolling expansion machine, a base and a main roller seat are connected into a whole framework structure through four upright posts, so that the strength and the rigidity are very high. The vertical rolling expansion machine has the advantages that the size is small; the weight is light; the occupied area is small; the manufacturing cost is low; the feeding and the discharging are convenient; the mold replacement is simple, convenient and fast; the efficiency is high; the installed power is low; the energy is saved; the environment-friendly effect is achieved; the rolling pressure is great; the rolling expansion on large-scale ring elements can be realized; and the vertical rolling expansion machine can particularly adapt to the rolling expansion processing of titanium alloy and high-temperature alloy.

Description

technical field [0001] The invention belongs to the technical field of forging equipment, and in particular relates to a vertical rolling machine and a rolling method. The vertical rolling machine is a new type of large-scale ring rolling numerical control forging equipment. Background technique [0002] In the modern machinery, automobile, tractor, construction machinery, petrochemical, bearing, aerospace, and wind power nuclear power and other manufacturing industries, rolling machines are widely used to complete the rolling and forming process of ring-shaped and cylindrical parts. The current rolling machine can roll the mass range from 1kg to 30T, and the diameter range is from 10mm to 8000mm, and the larger one can reach more than 10000mm. [0003] According to the installation form of the frame, the rolling machine can be divided into two types: vertical and horizontal. The existing vertical rolling machine is limited by the structure, the rigidity of the frame is poor...
