Description

Shear removal device of shear cutter of side cutter

The present invention automatically detects that the shear scraps generated during the work of the side cutter cutting both sides of the steel sheet go along with the sheared steel sheets, and greatly improves the quality scrap rate by separating and removing the scraps. It relates to a shear failure scrap removal device of a side cutter.

In general, the steel sheet (S) produced in the steel mill is wound in a coiled state on a tension reel (not shown), and before being shipped outside, as shown in Figures 1 and 2, the side installed on the pass line (Pass line) The upper and lower knives 111 and 112 of the cutter 110 cut and cut both sides of the steel sheet S according to the demand width of the demand price, and the burrs on both sides generated during the cutting are cut into the side cutters. It was removed by a pair of burr removal work roll 121 and a burr removal back-up roll 122 passing through the cut steel plate (S) installed in pairs in front of 110.

Shear failure scrap (hereinafter referred to as scrap) (S1) generated by cutting the both sides of the steel sheet (S) of the side cutting machine (110) (S1) is not discharged to the outside, the pass along with the steel sheet (S) proceeds in one direction due to shear failure In order to damage the product steel sheet (S) or damage the peripheral equipment while being mixed in the line or wound on another roll member such as a take-up roll, conventionally, the worker always cuts while watching the cutting operation state of the side cutter 110. In order to prevent the scrap S1 from progressing with the steel sheet S, the cutting poor state of the steel sheet S is frequently monitored, while the pass line is stopped when the scrap S1 is generated, and then a worker is directly injected into the scrap S1. ) The defective part was removed manually.

However, the conventional removal process for processing the scrap (S1) generated during the cutting of both sides of the steel sheet is performed after the defective sheared scrap (S1) has been carried out along the pass line to some extent, after generating a product defect In addition, the failure rate for the finished steel sheet can not be fundamentally prevented, and the scrap (S1) reprocessing and subsequent actions are delayed to gradually increase the product defective rate, while causing a safety accident for the worker during the removal operation.

Therefore, the present invention is devised to solve the problems described above, the purpose is to break the roll member, the finished product, etc. while proceeding with the sheet steel sheet shearing scrap generated during the cutting operation of the side cutter, The present invention is to provide a device for removing shear defects of side cutters that can automatically detect and separate defects so as not to cause defects, thereby reducing product defect rates and preventing operator accidents.
