A corrugated rolling mill with hydraulic pressure for special-shaped back-up rolls

Abstract

The invention belongs to the technical field of composite plate rolling and forming and particularly relates to a hydraulic screw-down corrugated roller rolling mill with special-shaped supporting rollers. The hydraulic screw-down corrugated roller rolling mill comprises a mechanical part and a hydraulic part. The mechanical part comprises the special-shaped supporting rollers, a special-shaped supporting roller balancing cylinder, a screw-down oil cylinder, working rollers, a frame and the like. The hydraulic part comprises a transmission side screw-down system, an operation side screw-down system, an upper special-shaped supporting roller balancing system, a self-adaptive lining plate system and an upper working roller balancing system. According to the hydraulic screw-down corrugated roller rolling mill, through the use of the special-shaped supporting rollers, the bending phenomenon of the working rollers under the working condition of large rolling force is avoided, and the service life of the working rollers is prolonged; and through the use of the self-adaptive lining plate system, the stability of the rolling mill is improved, the horizontal vibration of supporting roller bearing seats and working roller bearing seats in the frame is reduced, and the yield of composite plates is increased.

Description

technical field [0001] The invention belongs to the technical field of composite plate rolling and forming, and in particular relates to a corrugated rolling mill for hydraulically pressing special-shaped backing rolls. Background technique [0002] The traditional composite plate rolling production process is that the upper and lower work rolls of the rolling mill are respectively rolled with flat rolls in contact with the two metals, so as to realize the horizontal and vertical extension of the two metals. However, in actual production, due to the upper and lower two The elongation of different metals is different, it is easy to cause large curvature warping of the metal, and continuous production cannot be performed. Composite plate corrugated roll rolling technology is a transformative and subversive technology, which can promote better metallurgical bonding of two materials, improve bonding strength, and realize continuous production. During the rolling process of clad...
