Description

Technical Field

[0002] In industries like petrochemicals, large containers or storage tanks are often required, and these containers or tanks need to be edged, which requires angle steel rings. Carbon steel angle steel rings are typically processed using flame bending, resulting in poor appearance and difficult to control bending quality. Stainless steel angle steel rings, on the other hand, must be processed in a factory equipped with large hydraulic bending machines, resulting in high processing and transportation costs.

[0003] The publication number is CN206199940U, which is a stainless steel angle steel ring processing device. It includes a platform, a limiting column is fixedly installed on one side surface of the platform, and a hydraulic jack is installed under the limiting column. The jack rod of the hydraulic jack faces the limiting column, and an arc block is fixedly installed on the end of the jack rod of the hydraulic jack. The curvature of the arc block is consistent with the curvature required by the stainless steel angle steel to be processed. The cross-section of the limiting column is a regular rectangle, and the width of the limiting column is greater than the width of the arc block. The bottom of the limiting column is provided with a concave surface adapted to the arc surface of the arc block, and a gap is left between the bottom of the limiting column and the arc block to accommodate the stainless steel angle steel. The utility model has a simple structure and is easy to use. The stainless steel angle steel ring can be processed at the construction site, saving costs. Moreover, the utility model uses the stainless steel angle steel to continuously move forward to bend the stainless steel angle steel, which can control the bending forming appearance of the stainless steel angle steel and improve the bending quality.

[0004] The above equipment can perform rounding and bending of angle steel, but it cannot output the angle steel quickly after rounding, which is not conducive to continuous operation, so it needs to be improved. Utility Model Content
