Hot-rolled ribbed steel bar four-slit inlet guide online centering device

Abstract

The invention discloses a hot-rolled ribbed steel bar four-slit inlet guide online centering device. The hot-rolled ribbed steel bar four-slit inlet guide online centering device comprises a hole typemarker, a standard light-transmitting lining bar and a laser pen. The hole type marker is mounted on a lower roll of a press, and a light-transmitting hole is formed in the hole type marker. One endof the standard light-transmitting lining bar is mounted in an inlet guide on a press guide beam, and a light-transmitting groove is formed in the middle of the standard light-transmitting lining bar.The laser pen is fixed to the other end of the standard light-transmitting lining bar, a pen point of the laser pen is aligned to the light-transmitting groove, and the laser pen is used for emittingvisible light beams. The visible light beams can spread in the light-transmitting groove along the light-transmitting groove. The hot-rolled ribbed steel bar four-slit inlet guide online centering device has the beneficial effects that precise centering of the guide is achieved fast, dependency on the experience of a worker is reduced, and standard production is achieved fast; and process accidents are reduced, the product quality is improved, and the four-slit production period is shortened.

Description

technical field [0001] The invention relates to the technical field of steel rolling equipment, in particular to an online centering device for four-slit entrance guides of hot-rolled ribbed steel bars. Background technique [0002] The four-splitting technology of hot-rolled ribbed steel bars is an advanced rolling technology that simultaneously rolls one rolled piece into four finished products through a special pass and guide. This technology can not only greatly increase the output of small-sized hot-rolled ribbed steel bars, but also greatly reduce the overall energy consumption and production costs. It is an energy-saving and efficient emerging rolling technology encouraged by the state. [0003] Since the four-wire cutting technology of hot-rolled ribbed steel bars was introduced from Baden, Germany, it has developed by leaps and bounds in recent years. The localized technological innovations, including the pass type and the design of guide guards, are at the forefron...

AI Technical Summary

Problems solved by technology

[0010] The embodiment of the present application provides an online centering device for the four-segmented import guide of hot-rolled ribbed steel bars, which solves the difficulty in quickly realizing the guide in the production process of hot-rolled ribbed steel bars using the four-segmented hot-rolled ribbed steel bar technology. The technical problem of precise centering of guards has realized the rapid realization of accurate centering of guides and guards, reducing the dependence on workers' experience, quickly realizing standardized production, reducing process accidents, improving product quality, and shortening the technology of four-cut production cycle Effect
