Problems solved by technology

Since the width of the PS plate base strip is narrow from 650mm to 1660mm, and the span is relatively large, only small-sized blanks can be used for the production of the narrow PS plate base strip, which causes a lot of waste to the equipment capacity of the factory. Low efficiency, low yield
How to improve the slitting process of PS version aluminum-based strips to improve product quality, yield, and reduce production costs, there is still a big gap in China at present

Embodiment 1

[0022] The upper part of the circular knife assembly rack of the slitting machine row is provided with three slitting circular blades, and the lower part is provided with four slitting circular knives; the two sides of the lower part are respectively provided with a slitting circular blade which is close to the slitting circular blades on both sides of the upper part. In the middle of the lower part, there are two circular blades that are arranged close to the left and right sides of the circular blade in the middle of the upper part.

[0023] The PS plate-based aluminum coil that has been rolled to the finished thickness is first straightened and cleaned by the stretch bending straightening machine. After the strip is straightened, the flatness is less than 10I and the wave height cannot exceed 3mm.

[0024] The straightened aluminum coil is slit on both sides by the slitting machine row, and the slitting circular blades on both sides of the circular knife assembly frame are p...

Abstract

The invention provides a longitudinal cutting striping method for a PS-edition aluminum-based strip. The method comprises: a PS-edition base aluminum coil which is rolled to have the thickness of a finished product is straightened and washed via a stretch-bending straightening machine series, and then is subdivided by a longitudinal cutting machine series; a circular-cutter assembly frame of the longitudinal cutting machine series adopts the following quantity of striping circular-blade strips: the ratio of an upper part to a lower part is 3:4 or 4:3; the longitudinal cutting machine series performs bilateral longitudinal cutting on the aluminum coil; and the edges of striping circular blades on two sides of the circular-cutter assembly frame are provided with rubber isolating rings respectively. As the method adopts bilateral longitudinal cutting PS-edition aluminum-based strip, production efficiency is improved by 50 percent, and the upper and lower surfaces of the stripped strip are free from scrapes or scratches, aluminum powder aggregation, depressions, protrusions and other quality defects. The method can obviously save energy, reduce consumption, improve yield and production efficiency, can meet the requirements of high-grade PS printing aluminum strip on high surface quality, strip shape and thickness difference, and can realize large-scale production.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy manufacturing, and more specifically relates to a method for longitudinally cutting and stripping a PS plate aluminum-based strip. Background technique [0002] At present, the domestic production of PS plate base strips is produced by a single process. Since the width of the PS plate base strip is narrow from 650mm to 1660mm, and the span is relatively large, only small-sized blanks can be used for the production of the narrow PS plate base strip, which causes a lot of waste to the equipment capacity of the factory. Low efficiency and low yield. For how to improve the slitting process of the PS plate aluminum-based strip to improve product quality, yield, and reduce production costs, there is still a large blank in China at present. Contents of the invention [0003] The purpose of the present invention is to provide a slitting and slitting method for S-version aluminum-based strips. T...
