Flying shear device for hot-rolled bars

Abstract

The invention provides a flying shear device for hot-rolled bars, which comprises: a flying shear mechanism, two sides of which are respectively provided with an inlet end and an outlet end; an inlet guide groove formed in the inlet end of the flying shear assembly; and an outlet guide groove formed in the outlet end of the flying shear assembly, wherein the outlet guide groove comprises a support and a guide groove body arranged on the support, an inlet horn section, a steel passing channel section, a suspended falling section, an inclined plane guide section and an outlet section which are sequentially connected are arranged in the guide groove body, a stepped guide plate is obliquely arranged at an inlet of the steel passing channel section, and an inclined plane guide assembly is arranged at the inclined plane guide section. According to the invention, a cutting head can be effectively prevented from directly flying into the steel passing channel, and accidents caused by the fact that a rolled piece droops due to gravity to impact the inclined plane guiding lower edge and transversely penetrates out of the guiding groove are avoided.

Description

technical field [0001] The invention belongs to the technical field of iron and steel metallurgical equipment, in particular to a flying shear device for hot-rolled bars. Background technique [0002] Flying shear is a very critical piece of equipment in the hot-rolled bar production line. Its main function is to cut the head, cut the tail and break the rolled piece to ensure the shape and size of the head and tail of the rolled piece, while avoiding the head and tail of the rolled piece. Steel stacking accidents caused by uneven deformation or warping in downstream racks or steel passages. In order to make the rolled piece accurately enter the position of the cutting edge of the flying shear, there are guide grooves on the upstream and downstream of the flying shear. The upstream guide groove is called the inlet guide groove, and the downstream guide groove is called the outlet guide groove. [0003] The outlet guide grooves used in existing flying scissors are generally d...

Problems solved by technology

[0004] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a flying shear device for hot-rolled bars, which is used to solve the problem that the guide groove in the flying shear device in the prior art cannot effectively prevent the "flying" of the cutting head. "In" guide groove and steel stacking problems caused by the gravity drooping of the head of the rolled piece
