Description

Quadruple independent support five-roller straight head machine for wide plate

Technical Field

The utility model belongs to a sheet metal straightening equipment, concretely relates to five-roller straight head machine.

Background

In the rolling production of plate and strip materials, the rolled products often have the defects of wave bending, buckling and the like due to the influence of uneven temperature and deformation of rolled pieces, uneven cooling after rolling, transportation and other factors. Therefore, rolled steel must be corrected to reach the quality standard specified by the state and meet the use requirements of users.

The existing straight-head equipment has various models, the diameter of a working roll is generally 80, 100, 120, 140, 150, 180, 200 and 250 (unit is mm), and the equipment is divided into coarse working roll straight-head equipment and fine working roll straight-head equipment according to the diameter of the working roll. The coarse working roll straightening equipment is used for straightening thick plates, for example, the straightening equipment with the working roll diameter of 250mm can straighten aluminum plates with the thickness of 5-10 mm and the width of 2600 mm; the thin working roll straight-head device is used for straightening thin plates, for example, the diameter of a working roll is 140mm, and only aluminum plates with the thickness of 0.7-2 mm and the width of 2600mm can be straightened. The thin roller structure for the thin plate and the thick roller structure for the thick plate in the existing straight-head equipment have narrow application range.

With the progress of society and the development of science and technology, in order to meet the requirement of users on the continuous improvement of the quality of metal plates, the requirement of people on straight-head equipment is continuously improved, the straight-head equipment needs stronger adaptability, and a working roll of a conventional double straight-head machine structure cannot meet the strength requirement and cannot be used for processing plates with the width of 2.6m and the thickness variation range of 12 times.

the lower roll system component comprises three lower working rolls, and the middle parts of the lower working rolls are supported by a lower supporting roll set; the lower supporting roller set comprises more than two lower supporting roller pairs which are sequentially arranged along the axial parallel direction of the lower working roller, the lower supporting roller pairs comprise two lower supporting rollers, and each lower supporting roller is fixed on a lower cross beam.

And bases of the oil cylinders are fixed on two sides of the upper part of the frame.

The diameters of the upper working roll and the lower working roll are 80-250mm, and the diameters of the supporting roll and the lower supporting roll are 39-120 mm.

Two ends of each lower working roll are arranged in a lower roll system bearing block which is arranged at the lower part of the machine frame.

The oil cylinder is opened quickly, the oil cylinder is called as an oil cylinder for short, the speed of the oil cylinder is 80mm/s, and the speed of fine adjustment of the speed reducer is 2 mm/s. The speed of the oil cylinder is higher than the fine adjustment speed, and the oil cylinder is mainly used for opening when threading, only two limit positions, namely the longest limit position and the shortest limit position, can be accurately positioned at any position by the speed reducer, and is used for adjusting the position of a working roller when the straightening machine works to ensure the straightening effect. Therefore, the oil cylinder is opened quickly.

The supporting roller comprises a shaft, a roller sleeve is sleeved outside the shaft through a bearing, and two ends of the shaft are fixed on the arc supporting surface of the cross beam. The roller sleeve supports the working roller and can rotate along with the working roller, so that the supporting effect is achieved.

The utility model discloses increase independent support below every upper/lower working roll, solved upper/lower working roll intensity problem, the upper working roll possesses the function of independent adjustment simultaneously, and the adjustment of upper working roll includes the coarse adjustment of realizing by oil cylinder piston rod is flexible from top to bottom and the fine setting that is realized by the reducing gear box.
