Description
Technical Field
The invention belongs to the field of metallurgy, and particularly relates to a device for grinding the edge of a sheared strip steel.
Background
In order to meet the requirements of different users on the width of the strip steel, a strip steel edge cutting device, namely a circle shear, is arranged on a finishing machine group, and the edge of the strip steel can present a corner collapse area, a cutting area, a tearing area and an edge buckling area through the shearing of the circle shear. The disk shears can cause the tearing area to be rough due to the shearing process characteristics of the disk shears and generate burrs. Generally speaking, the machine set can adopt a deburring machine to carry out edge pressing treatment on burrs in the edge buckling area of the circle shear, and the working principle of the deburring machine is to utilize a roller or a wheel with a certain roller shape to carry out extrusion treatment on the edge of the strip steel. However, there is no corresponding measure for the "burrs" in the tearing zone of the strip. Along with the improvement of the requirements of downstream customers on the quality of the cut edge of the strip steel, a 'burr' treatment process and equipment for a tearing area of the strip steel are urgently needed. For example, with respect to enamelled steel produced by some downstream customers, burrs in the tear zone of the strip can cause problems in the enamelling process. Because the burrs of the tearing area are different from the burrs of the edge buckling area and can be pressed down through the burr pressing, a process and equipment capable of grinding the burrs of the side face of the strip steel must be developed. At present, the existing strip steel edge grinding device generally has the following problems: 1. only the edge-trimming area is polished, and no device special for polishing the edge-trimming tearing area of the strip steel is provided; 2. the occupied space is large and heavy, and the interference to other equipment can be caused when the device is added into a unit; 3. the grinding effect is not obvious; 4. some grinding devices are too single in targeted design and cannot adapt to the change of the specification of the strip steel; 5. the device is inflexible, and the grinding force is not adjustable.
