Abstract

The invention relates to a flange processing machine, in particular to an aggravating vertical type ring rolling machine which solves the problem that the quality of a ring rolling not high during the flange processing process. The invention includes a base; a horizontal working platform and a motor are arranged on the base; a main rotating mould is arranged on the horizontal working platform; the main shaft of the main rotating mould is connected with the motor by a coupling; a mandrel is arranged below the main rotating mould; the two sides of the main rotating mould are provided with holding rollers; a limitation device is arranged above the main rotating mould; a distance measuring device with a distance measuring wheel is arranged below the main rotating mould. The invention is suitable for processing the flanges with large coaxial dimensions like a lapped flange and a high neck flange; the largest processing diameter is 1100mm and the largest thickness of the flange is 140mm.

Description

technical field [0001] The invention relates to a flange processing machine, in particular to a weighted vertical ring rolling machine. Background technique [0002] Flanges and other ring parts are widely used in petroleum, chemical, metallurgy and other industries. At present, the manufacturing and forming technology of flanges and other ring parts mainly adopts free forging into cake pieces, punching, horse frame reaming, rolling and rolling. , and finally formed by machining. Rolling and rolling is to first use horse frame reaming or other forging methods to make ring blanks, and then use rotating dies on the ring rolling machine to continuously press and form the blanks locally, so that the overall wall thickness of the rings is reduced and the diameter is enlarged. The cross-sectional profile is formed to make it a ring blank with simple shape and size, and then the cross-sectional shape is machined by a large vertical lathe. The existing ring rolling machinery has a...
