Problems solved by technology

At present, the traditional tandem cold rolling mills all use single-drum coilers, and two sets are configured to realize continuous coiling of strip steel. This not only increases the floor area and equipment, but also increases the maintenance amount of equipment and the source of equipment failure.

Abstract

The invention belongs to the forming technical field, and relates to a dual-reel coiler. The coiler is arranged at an outlet of a cold-strip steel tandem mill; two reels are arranged in a rotary box body; the reels rotate around respective central spindle; the central spindles are driven by the input of two hollow shafts with public axes respectively, and the reels are driven by a rotating hydraulic cylinder to realize dilatation; large gear rings at the periphery of the rotary box body are engaged with gears, are supported by a guide roller, and are driven by a driving device to rotate; a brake is driven by a braking hydraulic cylinder to brake, and a clamping device is driven by a clamp hydraulic cylinder to clamp; and the reels transfer motion by a separate motor through a gear deceleration system, and are arranged in the public rotary box body (rotating disc) capable of rotating around the spindles so as to realize continuous and alternant strip steel reeling. The dual-reel coilercan obviously improve productivity, improve the quality of steel coils, save installation space and bring considerable economic and social benefits, and can be applied to cold tandem mill sets.

Description

technical field [0001] The invention belongs to the technical field of forming, and relates to a double-drum coiler. Background technique [0002] With the continuous expansion of the production capacity of the iron and steel industry in recent years, especially the output of cold-rolled strip steel has also continued to increase. Equipment. Especially for cold tandem rolling units, shortening the length of the unit, reducing coiling failures, reducing production costs, and improving productivity have become the goals pursued by various cold rolling manufacturers. Therefore, they put forward high efficiency and reliability of coiling equipment higher requirement. At present, the traditional tandem cold rolling mills all use single-drum coilers, and two sets are configured to realize continuous coiling of strip steel. This not only increases the floor area and equipment, but also increases the maintenance amount of equipment and the source of equipment failure. . Content...
