Band tail shearing device adopted after hot rolling intermediate billet shearing pressure welding

Abstract

The invention relates to a band tail shearing device adopted after hot rolling intermediate billet shearing pressure welding, and belongs to the field of band steel searing pressure welding equipment.According to the device, a hydraulic cylinder drives a lower shearing device with mechanical limiting to ascend and descend so as to achieve back driven shearing of a band tail at the lower surface of a middle billet. A linear displacement sensor precisely controls an upper shearing device to ascend and descend so as to achieve height positioning of connection belt heads of middle billets of different thicknesses. A hydraulic translation device drives the upper shearing device to move horizontally so as to achieve back driving shearing of the band head at the upper surface of the middle billet. An upper cutting edge and a lower cutting edge adopt the L-shaped structural style, and the requirement that adhesion between the band head, the band tail and the middle billet is removed while residual connecting faces of the middle billet, the band tail and the band head are cut off is met, so that the phenomenon that the band head, the band tail and the middle billet are adhesively connectedand are not disengaged is avoided and the tearing influence caused by combination faces of the middle billets is avoided.

Description

technical field [0001] The invention belongs to the field of strip steel shearing and crimping equipment, in particular to a strip tail shearing device after shearing and crimping of a hot-rolled intermediate billet. Background technique [0002] In the production of traditional strip hot continuous rolling and finishing mills, a single intermediate billet is rolled, and the processes of strip threading, accelerated rolling, decelerated rolling, steel throwing and tail flicking when entering the finishing mill are inevitable. Therefore, it is difficult to ensure the thickness difference between the head and the tail of the strip and the uniformity of the strip threading quality, and the rolling operation rate and yield are also limited to a certain extent. [0003] With the new and higher requirements for the quality of thin plates in industries such as automobiles and home appliances, size, shape accuracy, surface and intrinsic quality have become equally important quality ...

AI Technical Summary

Problems solved by technology

[0005] However, after the shearing and crimping process, there is a 200mm long tape head on the top and a 200mm long tape tail on the bottom, which needs to be processed. If the treatment is not good, it will cause the tape tail to stick to the intermediate billet and not fall off or cause the intermediate billet The tearing of the joint surface, these problems will affect the production of the subsequent process
