Belt winding aid and method for aiding in cold steel strip winding by using same

Abstract

The invention relates to a belt winding aid and a method for aiding in cold steel strip winding by using same. The trolley of the belt winding aid is connected with a first hydraulic cylinder and slides horizontally along a base under the push of the first hydraulic cylinder, and a turning arm, of which the initial positions are below, is arranged on the two sides of the end part of the trolley parallelly and connected with a second hydraulic cylinder movably and can rotate upward under the push of the second hydraulic cylinder; a guide plate is arranged above the turning arm and keeps a fixed distance from a winding drum; a belt is tensioned or loosened by a third hydraulic cylinder, and the turning arm drives the belt to be wound on or released from the winding drum through a belt wheel arranged on the turning arm; and the upper end of the turning arm is provided with a rocker which can rock up and down, and a roller is arranged on the end part of the rocker. When the device and the method are adopted, an aid is provided for the winding of a thick steel strip, the steel strip can effectively wind on the winding drum, and the edge of a steel coil is ordered; and the device and the method are applicable to various planishers and the thickness range of cold steel strips to be wound with aid is enlarged considerably.

Description

technical field [0001] The invention belongs to the technical field of strip steel coiling, and in particular relates to a belt coiling aid and a method for coiling cold strip steel by using the aid. Background technique [0002] The rolled cold strip head needs to be coiled 3 to 5 times on the coiler before the strip can be tensioned and coiled. Usually, the head is clamped by the jaws of the coiler or a belt coiler is used to assist coiling. Different from the rolling mill, since the cold strip is flattened by the tempering machine and becomes a finished coil, a coiler without jaws is required. At this time, regardless of the thickness of the strip, it is necessary to rely on the belt coiler to assist coiling. [0003] Conventional take-up belt winders such as figure 1 shown. The trolley 3 slides in the base 1 to the coiler drum 7 under the push of the first hydraulic cylinder 2. The trolley 3 is equipped with a plurality of pulleys 5, and the belt pulley 5 is wound with...

AI Technical Summary

Problems solved by technology

Experience shows that for commonly used low-carbon steel materials, the thickness of 1.5-1.6mm is a critical point, and due to the self-weight of the strip, the lower coiling is more unfavorable than the upper coiling

If the strip steel cannot wrap the reel tightly, the coiling tension will fluctuate, resulting in uneven edges of the steel coil, which will affect the quality of the finished product
