A curved corrugated plate production equipment

Abstract

The invention provides arc corrugated plate production equipment, and relates to the field of cold roll forming. The production equipment comprises a base, and a rolling unit mounted on the base. The rolling unit comprises multiple mold roller sets arranged at intervals; the multiple mold roller sets are arranged by taking the form of an arc trajectory; each mold roller set consists of an inner roller positioned on the inner side of the arc trajectory, and an outer roller arranged on the outer side of the arc trajectory; an arc corrugated plate rolling forming path for enabling a steel plate to pass through is formed among the multiple mold roller sets; the steel plate passes through the multiple mold roller sets in sequence along the corrugated plate forming path; and under the effect of clamping feeding force of the inner rollers and the outer rollers, the steel plate is machined into a bent arc with ripples gradually formed thereon, and an arc corrugated plate is thus formed. The production equipment completes the ripple formation and the arc bending in the same procedure.

Description

technical field [0001] The invention relates to the field of cold-bending forming, and is a curved corrugated plate production equipment used for rolling forming longitudinal corrugations of spliced ​​corrugated pipes. Background technique [0002] Curved corrugated plates are mainly used in spliced ​​corrugated pipes, which are widely used in culverts in roads, railways, bridges, passages, retaining walls, and various mines, roadway retaining walls, etc. . The new application frontier of corrugated plates is the urban pipe gallery, which is a circular corrugated pipe made of corrugated metal plates or arc corrugated plates, and other shapes such as dustpan, horseshoe, arch And special-shaped bellows such as pear-shaped. [0003] At present, the above-mentioned corrugated plate processing is mainly completed by two processes of forming and arc bending. The existing way of roll forming longitudinal corrugated plate, the forming principle is to arrange several forming rolle...

AI Technical Summary

Problems solved by technology

Due to the excessive bending force, there are inevitably problems such as poor bending effect, poor lap joint degree of plate side when making bellows, etc.

In addition, the corrugated plate corrugated forming and arc bending used for arc bending assembly are produced by two independent processes. The corrugation is formed first, and then the arc is bent, which not only causes discontinuous production of the forming process, but also increases the working pressure of the arc bending process.
