Semicanal formation rolling machine

Abstract

A rolling mill for forming a semi-tube belongs to the technical field of rolling, and is used for solving the problem of one-time forming of steel strips. The technical proposal is that the rolling mill comprises a frame, a rolling part, a transmission part and a cogging adjusting mechanism. The rolling part consists of a guide roller, a pre-forming roller, a semi-forming roller, a forming roller and a rolling roller which are arranged in sequence. The upper roller and the lower roller of the guide roller are cylindrical rollers, while the other four rollers respectively consist of upper rollers and lower rollers which are provided with mutually matched arc roll surfaces. The rolling mill can roll the steel strip with the thickness of 2-3mm into semi-tubes in different diameters. The thickness of the wall of the semi-tube rolled by the rolling mill is evenly changed with the curvature thereof, and the semi-tube shows no folding. The finished product semi-tube has the advantages of low rigidity and good flexibility, and can be smoothly and spirally wound or directly laid on a cylindrical shell of a device while arranging the device.

Description

technical field [0001] The invention relates to a rolling mill, in particular to a semi-pipe special rolling mill for rolling strip steel into an arc-shaped section, and belongs to the technical field of rolling. Background technique [0002] With the continuous development of science and technology, the heat exchange methods of non-standard equipment in the pharmaceutical, chemical, food and other industries have been greatly improved. A continuous half-pipe is laid spirally or linearly on the shell of the tank to exchange heat with the medium in the equipment. The use of half-pipe heat exchange design can increase the capacity of heat exchange equipment, reduce the pollution of medium heat exchange, maintain the strength and rigidity of non-standard cylindrical equipment, and effectively reduce the wall thickness of the cylinder and reduce the relative net weight of the equipment. Although the half-pipe heat exchange device has the above-mentioned advantages, due to its r...

AI Technical Summary

Problems solved by technology

Although the half-pipe heat exchange device has the above advantages, due to its relatively small amount, there is a lack of special equipment for processing half-pipes, and the product parameters of half-pipe processing are difficult to control and the production efficiency is low.
