Vertical and horizontal shearing combination production line for high-strength thick steel plates

Abstract

The invention provides a vertical and horizontal shearing combination production line for high-strength thick steel plates based on the advantage of multifunction of an existing vertical and horizontal shearing combination production line, so that vertical shearing and horizontal shearing functions are organically combined, various machining processes are realized, and production requirements on high efficiency and high quality are met. The vertical and horizontal shearing combination production line for the high-strength thick steel plates comprises a vertical shearing line and a horizontal shearing line which are controlled by an electric control system and a hydraulic pneumatic lubricating system, a second uncoiler is arranged on the horizontal shearing line, and a transition bench is arranged between the vertical shearing line and the horizontal shearing line. The vertical shearing line has independent functions of uncoiling, vertical shearing and coiling, the horizontal shearing line has independent functions of uncoiling, leveling, horizontal shearing and stacking, the whole vertical and horizontal shearing combination production line has the functions of uncoiling, leveling, vertical shearing and coiling, leveling and horizontal shearing, multi-strip horizontal shearing and automatic stacking, the requirements of various high-strength thick steel plates on various machining processes are met, the vertical and horizontal shearing combination production line is high in utilization rate, multifunctional and high in automation degree, and the production requirements on high efficiency and high quality are met.

Description

technical field [0001] The invention belongs to metal coil plate shearing unit equipment, and in particular relates to a high-strength thick steel plate vertical and horizontal shear combined production line applied in the fields of heavy-duty automobile bottom beams, steel structures, and special steel plate processing. Background technique [0002] The metal coil longitudinal and transverse shearing unit is a large-scale equipment with a high degree of automation and a combination of multiple machines with different functions. At present, the longitudinal and transverse cutting production lines of metal coils at home and abroad can be roughly divided into three categories: [0003] 1. Slitting production line: After uncoiling, slitting (that is, cutting into several narrow strips of a certain width along the length direction), the rolled wide metal sheet is processed into metal narrow strips by winding and other processes, so that It is used in the mechanical, electrical ...

AI Technical Summary

Problems solved by technology

[0006] Although the third type of combined longitudinal and transverse shearing production line integrates the two functions of longitudinal shearing and transverse shearing, the processing method is still relatively simple. In addition to longitudinal shearing and transverse shearing, various processing techniques that combine longitudinal and transverse shearing have not been realized.

At the same time, when one kind of processing equipment with slitting function is working, the other processing equipment with cross-shearing function is idle; correspondingly, when using one kind of processing equipment with cross-shearing function, The processing equipment is idle, and its equipment utilization rate is low (50%), which increases equipment maintenance costs

Especially when the back-end cross-cut function is used, since the sheet passes through many equipment links, it is easy to cause defects such as surface scratches
