GWC14.5-80-1120 Assembled Silo Corrugated Sheet Roll Forming Machine


Maximum production speed: not less than 18 meters per minute (for non-perforated profiles, excluding cutting);
Bending precision: the maximum profile deviations (dimensions and shape) shall not exceed the tolerances specified in EN 10162 (or equivalent tolerances);
Bending quality: ability to bend the profiles of the specified configuration at the specified maximum steel thickness; cracking of the steel or metal coating is not permitted for all required steel grades, when observing the products under magnification ten times.

Features

1. This machine is designed to process steel coil into corrugated sheet with desired specification in one step, and this is available even for thicker steel.
2. Our product makes use of rollforming technology to fabricate the corrugations one after another, resulting in released internal stress, reduced spring back effect as well as improved product quality.
3. This corrugated sheet roll forming machine is most popular one among similar products on the market, and it can be tailored to best fit every customer's needs if relevant drawings are supplied. Meanwhile, the production process, including two options, is up to the customer.
a. Form the straight sheet with corrugation first, and then punch holes and curve the sheet outside the production line.
b. Shape forming, punching, curving and shearing operations are finished on the same production line automatically. There would be no straight edges on the sheet, thus the assembly is easy and the productivity is enhanced.


Patents
Our corrugated sheet roll forming machine has gained several patents, and here are some brief introductions.
1. One feeding device for curved corrugated sheet production line (ZL201020606332.1). It has the advantages of universal application, high automation level, safe and reliable operation, etc.
2. One bidirectional curving machine (ZL201120054585.7). It has upper and lower curving rollers, and the continuous curving method avoids straight edge on both sides of the sheet. As a result, the finished sheet is aesthetic and allows simple assembly.
3. One curved corrugated sheet forming line (ZL201120055257.9). There is a slitting machine at the back end to cut off the extra sheet in the transverse direction (width direction) which is caused by the rolling process, and the cut parts are collected by an automatic recycling device. With a simple structure, this sheet forming line is able to deliver reliable performance, thereby improving working efficiency and lowering labor cost.
4. One three-station punching machine (ZL201120055225.9). It uses a three-station punching die to conduct complete punching treatment to the corrugated sheet. It shows the advantages of high precision, low deviation and simple construction.
5. One curved corrugated sheet shearing machine (ZL201020606306.9). This is a universal device, and it uses the handwheel to adjust shearing angle and height.
