Cold-bending forming machine for high corrugated steel floor deck

Abstract

The invention relates to a cold-bending forming machine for a high corrugated steel floor deck. The cold-bending forming machine for the high corrugated steel floor deck comprises an automatic uncoiler, a machine frame, a guiding device, a lubricating device, a cold-bending forming roller set, a hydraulic cutting device and a stacking machine, wherein the automatic uncoiler is arranged at one side of the machine frame, and the stacking machine is arranged at the other side of the machine frame. The guiding device, the lubricating device, the cold-bending forming roller set and the hydraulic cutting device are sequentially installed on the machine frame, and the guiding device is arranged at one side of the automatic uncoiler. The cold-bending forming roller set comprises a plurality of rolls, and the rolls are unequally distributed at intervals. The cold-bending forming machine for the high corrugated steel floor deck has the advantages of being high in forming speed, applicable to cold rolling galvanized steel sheets or color plates with the rolling thickness of 0.7-1.5 mm and the yield strength of 230-350 MPa, or applicable to the construction steel floor deck with the rolling corrugated height of 120-220 mm and the substrate developed width of 900-1500 mm. By means of the cold-bending forming machine for the high corrugate steel floor deck, the coating or the plating of the rolled tubular products is not scratched, no visible bag-shaped wave, thus the forming quality of the products is enabled to be good.

Description

technical field [0001] The invention relates to a cold-bending forming machine, in particular to a high-wave steel floor deck cold-bending forming machine with non-equidistantly arranged roll groups, and belongs to the technical field of metal cold-bending forming equipment. Background technique [0002] When the high-wave steel floor deck is cold-formed, because of the large difference in the diameter of the forming rolls, that is, the large difference in the linear speed of the roll surface, the rolls will slip on the surface of the product plate and scratch the surface of the product plate. When the scratch is serious It will damage the surface coating and plating of the product plate. As the wave height of the product plate increases, the difference in the diameter of the rolls increases, and the greater the forming speed, the greater the difference in line speed on the surface of the large and small rolls, the more serious the slipping and scratching, and the coating or...

AI Technical Summary

Problems solved by technology

[0003] In order to avoid damage to the surface coating or plating of the product, the forming speed of the steel floor deck with a wave height of about 100mm is controlled below 15m / min, which greatly affects the production efficiency of the forming machine

[0004] In addition, the corrugated hypotenuses of high corrugated steel floor decks are large in size, which is prone to "pocket waves" and affects the appearance of finished panels
