Roll type optimization method used for burr presser of recoiling unit

Abstract

The invention discloses a roll type optimization method used for a presser of a recoiling unit, belonging to the field of cold rolling. The roll type optimization method comprises improvement design for the roll type of a burr pressing roll and reasonable determination for parameters of a burr pressing section of the burr pressing roll; on the basis of a current flat roll structure, the roll type of the burr pressing roll is improved into two parts of a flat burr pressing section and arc transition sections; the flat part of the middle position of the burr pressing roll is the burr pressing section; and the arc transition sections with the radius of R are located on the two ends of the burr pressing section. The roll type optimization method aims to overcome defects existing in the current roll type of the burr presser; the roll type of the burr pressing roll is improved by combining equipment and technical characteristics of a recoiling process of strip steel; by reasonably determining the parameters of the burr pressing section of the burr pressing roll, strip steel indentation during the burr pressing process can be avoided, and burr pressing force is concentrated, so that the burr pressing effect is ensured; meanwhile, a positioning margin value in the width direction of the strip steel can be well given to the burr pressing roll; strict requirement of the unit on electrical control is lowered; and burr defects are effectively avoided.

Description

Technical field [0001] The invention belongs to the field of cold rolling, and particularly relates to a method for optimizing the roll shape of a press burr machine suitable for a recoiling unit. Background technique [0002] After the strip is trimmed in the rewinding unit, due to the different settings of the overlap amount and the gap amount of the disc shears, different degrees of burr defects will occur. [0003] Generally speaking, the unit will be equipped with a burr pressing device behind the disc shear device. Some units will use a pressing roller, and some units will be equipped with a pressing burr machine. [0004] However, no one has proposed an optimal design method for the roll shape of the embossing machine and the embossing roller. [0005] In fact, most of the press rolls and press burrs that are matched with most units are of straight roll or arc-shaped roll. figure 1 with figure 2 Schematic diagrams of the structure of the straight roll and the arc-shaped roll a...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide a method for optimizing the roll profile of a deburring machine for a recoiling unit, which aims at the defects existing in the existing deburring rolls and deburring machine roll profiles, and at the same time combines the process of strip steel recoiling The characteristics of the equipment and process can not only avoid the indentation of the strip steel during the deburring process, but also ensure the concentration of the deburring force, ensure the deburring effect, and at the same time give a good positioning of the deburring roller in the width direction of the strip margin, which reduces the stringent requirements of the unit for electrical control and effectively avoids the occurrence of burr defects
