Arc 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 arc corrugated plate production equipment used for roll forming longitudinal corrugations of spliced ​​corrugated pipes. Background technique [0002] Curved arc corrugated plates are mainly used in splicing corrugated pipes, which are currently widely used in culverts in highways, railways, bridges, passages, retaining walls, and various mines, roadway retaining walls, etc. . The new frontier of corrugated board applications is urban pipe corridors, which are circular corrugated pipes made of corrugated metal sheets or made of circular arc corrugated sheets, as well as other shapes such as dustpan, horseshoe, and arch. And pear-shaped corrugated pipes. [0003] At present, the above-mentioned corrugated board processing is mainly completed by two processes of forming and bending. The existing method of roll forming longitudinal corrugated board, its forming principle is to arrange...

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.
