Disk shear mechanism for withdrawal and straightening machine

Abstract

The invention discloses a disk shear mechanism for a withdrawal and straightening machine. The disk shear mechanism comprises a fixing seat, wherein an upper knife is arranged at the upper end of thefixing seat; the center of the upper knife is connected with an upper knife shaft; a lower knife is arranged at the lower end of the fixing seat; the center of the lower knife is connected with a lower knife shaft; each of the upper knife shaft and the lower knife shaft is provided with a reference portion and a spacer body; each reference portion is arranged on the inner side of the correspondingspacer body; each spacer body is arranged between the upper knife / lower knife and the corresponding reference portion; a groove is formed in the end surface, which is in contact with the upper knife / lower knife, of each spacer body; the position, where the groove is located, of each spacer body is provided with a plurality of screw holes in a ring shape; adjusting bolts are arranged in the screwholes; and a gasket is arranged in each groove, and isolates the corresponding adjusting bolts from the side of the upper knife / lower knife. Adjustability of end surface parallelism obtained after assembling of knives is realized, and the technical problems that in an existing strip steel machining process, the quality of products is poor, the rejection rate is high, disc knives are prone to beingdamaged, and the cost is high are solved.

Description

technical field [0001] The invention relates to a disc shear mechanism of a tension leveler, which belongs to the technical field of strip steel processing equipment. Background technique [0002] The stretch bending straightening unit is referred to as "tension leveler", which is a kind of straightening equipment developed to meet the high requirement of strip straightness. It combines the advantages of roller leveler and stretch leveler. , its working characteristic is that under the joint action of the stretching of the tension roller and the continuous alternating and repeated bending of the bending roller, the strip is plastically elongated to obtain strip straightening, and it can eliminate the scoop, edge wave and camber of the strip and other ternary shape defects, significantly improving the quality of the plate shape. [0003] The steel spacer is one of the key parts of the disc shear, and it is also a part that requires high precision. The existing disc shear st...
