Online treatment device for large bar rolled piece bend

Abstract

The invention discloses an online treatment device for large bar rolled piece bend. The online treatment device comprises an overall framework, a horizontal straightening roller pair and a vertical straightening roller pair, the horizontal straightening roller pair is arranged on the left side and the right side of the overall framework, the vertical straightening roller pair is arranged on the upper side and the lower side of the overall framework, the horizontal straightening roller pair and the vertical straightening roller pair respectively form a horizontal straightening hole and a vertical straightening hole or jointly form a straightening hole, and roller gap adjustment driving devices for adjusting the positions of the horizontal straightening roller pair and the vertical straightening roller pair are further arranged on the overall framework. After the online treatment device is mounted on a large bar continuous mill finish rolling frame, a rolled piece is treated online by the horizontal straightening roller pair and the vertical straightening roller pair, the size of the straightening hole can be adjusted by the roller gap adjustment driving devices to adapt to bars with different specifications, and the online treatment device successfully solves the problems that rolled pieces still bend after cooling collection due to bending of finished product pass rolled pieces in the rolling process of a large bar production line, manpower is wasted in treatment and production cost is increased.

Description

technical field [0001] The invention relates to an on-line processing device, in particular to an on-line processing device for an elbow of a large bar rolled piece. Background technique [0002] Bars with a diameter of Φ50mm or more are prone to elbows during the rolling process of the finished product pass. This situation is common in major bar production plants. There are many reasons. The adjustment of the rolling mill guide is not good. The aging of the guard beam, the uneven cooling of the roll cooling water, the power of the motor and other factors will affect the stability of the rolling process, and then produce the elbow of the rolled piece. The direction of the elbow of the rolled piece is not fixed due to different influencing factors. Usually, the rolling mill adopts the method of straightening off-line after cooling and collecting to deal with this kind of problem, but generally only 1-2 Roots need to be straightened or fully straightened after sorting. At the...
