Correcting device before disc shear of stretch-bending straightening machine

Abstract

The invention discloses a correcting device before a disc shear of a stretch-bending straightening machine. The correcting device comprises a rack, wherein a fixed frame is arranged on the rack. A centering detection device which can detect the deviation position of strips to be conveyed is arranged behind the fixed frame, and a pair of fixed rolls is installed on the fixed frame. A swing frame is installed on the fixed frame through an articulated shaft, and a pair of swing rolls is installed on the swing frame. A hydraulic cylinder which can drive the swing frame to swing along the articulated shaft is installed between the swing frame and the fixed frame, and the strips to be conveyed sequentially bypass the swing rolls and the fixed rolls to be output. After the structure is adopted and the strips to be conveyed are deviated, the hydraulic cylinder can drive the swing frame to swing so as to correct deviation, and the deviation problem of the strips during shearing is completely solved. Meanwhile, the machine column speed is not influenced, and any surface scratching and sliding cannot be generated. The product quality is ensured, the intended production target is achieved, the rate of finished products is increased, and the economic benefit is increased.

Description

[0001] technical field [0002] The invention relates to an accessory device of a stretch-bending straightening machine, in particular to a pre-cut correction device for a disc of a stretch-bending straightening machine, which belongs to the technical field of cold-rolling processing equipment. Background technique [0003] Stretch bending straightening machine is a finishing equipment for stretching, straightening, cleaning and edge trimming of products; now users have higher and higher requirements for strip width precision, so the requirements for equipment performance are also getting higher and higher , sometimes the maximum amount of unilateral trimming is 7.5mm, and the staggered layer of the edge of the strip is within 0.5mm; some stretch-bending straightening machines are designed to make the edge of the strip smooth and clean, and the disc edge-cutting device is considered to be placed on the coiler. side, directly on the coiler after cutting. [0004] In the ...

Problems solved by technology

[0004] In the actual production of shearing, as the shearing time goes by, the width of the strip material will become narrower and wider due to the left and right swimming, that is, the two sides are equal from the beginning, and then the width of the single side of the broken side is erratic, sometimes even borderless Fragile, directly affecting the quality of finished products or causing scrap

[0005] Although the uncoiler of the prior art has a centering detection device, there
