A method for continuously deburring the edge of thin strip steel

Abstract

The invention discloses a method for continuously deburring the edge of a thin steel strip, which includes applying a certain tension to the front and rear directions of the thin steel strip, and deburring the edge-trimmed thin steel sheet through a deburring device. According to the thin steel strips of different widths, The screw rod is driven by the motor to adjust the deburring device to a proper position, and the position between the upper spherical pressing roller and the lower spherical pressing roller is roughly adjusted through the nuts and pads arranged at the ends of the upper and lower roller shafts; the upper and lower spherical pressing rollers are finely adjusted. The position of the roller is such that the position where the spherical roll diameter of the upper pressure roll is the largest is aligned with the position where the spherical roll diameter of the lower pressure roll is the largest. The present invention realizes the accurate alignment of the positions with the largest spherical diameters of the upper and lower pressing rollers by setting and adjusting the gaskets with different thicknesses on the sides of the upper pressing rollers, the wearing position of the upper pressing rollers is fixed, the service life is improved, and the burrs on the edge of the strip steel are rolled more evenly.

Description

technical field [0001] The invention relates to a method for deburring, in particular to a method for continuously deburring the edges of thin strip steel. Background technique [0002] In the prior art, burrs are generated after continuous edge trimming of the thin strip steel, and the burrs generally need to be continuously rolled to improve the surface quality of the edge. [0003] as attached figure 1 As shown, the main feature of this type of deburring device is to set a lower support roller, which is a driving roller, and there is a small pressure roller on each side of the strip, which can be opened and closed up and down driven by a cylinder. The motor drives the screw to move the small pressure rollers on both sides, and the position can be adjusted according to the width of the strip. The edge of the strip can achieve the deburring effect between the small pressure rollers and the support rollers. The problem with this device is that the roller surface between th...

Problems solved by technology

The problem with this device is that the roller surface between the pressure roller on the upper part of the strip and the support roller on the lower part of the strip is parallel, and the pressure roller forms a "surface contact" with the edge of the strip, which is easy to generate side waves and waves on the edge of the strip. Surface quality defects such as embossing, the surface of the support roll is also in contact with other parts of the lower surface of the strip, and the lower surface is prone to more scratches

The roller bodies of the upper and lower spherical rollers of this type of deburring device are cylindrical rollers, and some are directly replaced by bearings. The contact surface between the upper roller surface and the edge of the strip is large, and it is easy to produce embossing, burrs and scratches on the edge of the strip. surface quality defects

In addition, due to the large contact area of ​​the roller surface, the pressure between the upper and lower rollers is also large, which may easily lead to the unfixed wear position of the upper roller surface, uneven wear of the roller surface, and uneven rolling of burrs on the edge of the strip.
