Strip steel endless rolling shearing and crimping device

Abstract

The invention discloses a strip steel endless rolling shearing and crimping device, and belongs to the technical field of metallurgical machinery. The device comprises a shearing and crimping body andtwo transmission mechanisms. The shearing and crimping body is composed of a rack, an upper rotary drum, a lower rotary drum, an upper machine head, a lower machine head, an upper cutter head, a lower cutter head, an upper shear blade, a lower shear blade, an upper hydraulic cylinder, a lower hydraulic cylinder, a rotary drum bearing seat, a pressing hydraulic cylinder, upper and lower positioning gear blocks and a balance mechanism; the two transmission mechanism are connected with the upper rotary drum and the lower rotary drum correspondingly, and each transmission mechanism consists of atransmission shaft, a brake coupling, a speed reducer and a motor which are sequentially connected. The shearing and crimping work with one-time continuous head-cutting, crimping and tail-cutting actions for two strip steeps overlapped end to end in an endless rolling hot-rolled strip steel production line and the separate head-cutting or tail-cutting or segmenting work for the strip steels are realized, and the shearing and crimping equipment can be reconstructed and constructed by utilizing the existing conventional hot-rolled strip steel head-cutting and tail flying shear installation position, so that the endless rolling hot-rolled strip steel production is realized, and the blank of domestic and foreign technical equipment is filled.

Description

technical field [0001] The invention belongs to the technical field of metallurgical machinery, and in particular relates to equipment for endless rolling, shearing, and crimping of strip steel. Background technique [0002] In a common hot-rolled steel strip production line, it is generally necessary to process each steel plate to be rolled after heating, rough rolling, and then finishing rolling to process a hot-rolled coil with a required thickness. In such a rolling method, especially in the finish rolling process, there are problems that products with a thickness of 0.8 to 1.5mm cannot be rolled, or the production line is likely to stop due to poor engagement of the rolled material, and because the rolled material The problem that the yield rate is greatly reduced due to the poor shape of the front and rear ends of the material. Recently, in order to eliminate such problems and further increase production capacity, a pre-joining rolling method has been adopted. In this...
