H-shaped steel production process

Abstract

The invention discloses an H-shaped steel production process. The production process includes the following steps that (1) feeding is performed, specifically, coiled materials are put in an uncoiler through a feeding trolley; (2) material guiding is performed; (3) flattening is performed, specifically, strip steel is flattened and delivered to the next procedure through a clamping delivery flattening machine; (4) shearing and butt welding are performed, specifically, the tail of the former coil of strip steel and the head of the latter coil of strip steel are parallelly shorn firstly, and then the two sections of strip steel are welded together; (5) a loop material storage machine is provided; (6) clamping delivery is performed; (7) web S tackling is performed, specifically, the strip steel coming out of a clamping delivery device is rotated by 90 degrees from the horizontal position to form a vertical plate; (8) combined clamping delivery is performed; (9) welding fixing is performed, specifically, a welding fixing device is composed of a wing plate guiding device, a web upsetting device, a welding pressure device, a web limiting roller device and a bending correcting device; (10) welding is performed; (11) cooling is performed; (12) correcting is performed; (13) a pull-out rack is provided; and (14) flying sawing is performed. The H-shaped steel production process has the beneficial effects and advantages that the production efficiency is high, and the product quality is also high.

Description

technical field [0001] The invention relates to a production process of H-shaped steel, which is applied in the technical field of H-shaped steel production. Background technique [0002] In the production process of traditional H-shaped steel, because the speed is not controlled, the problem of production stop due to insufficient supply often occurs in the production process, which affects the output of the enterprise. In the traditional H-shaped steel production process, there is only the last correction process. The produced H-shaped steel is uneven and bent, which affects sales. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention discloses a production process of H-shaped steel with high production efficiency and high product quality, comprising the following steps: [0004] (1) Loading: Use a loading car with a lifting height of 350mm to put the coils with an inner diameter of 508-610mm and an outer diameter of 120...
