Rotary cutting type cut-to-length device for plate of moderate thickness
2012
The invention discloses a rotary cutting type cut-to-length device for a plate of moderate thickness. The rotary cutting type cut-to-length device for the plate of moderate thickness at least comprises a frame, a panel, an upper knife rest, a lower knife rest, a shear blade clearance adjusting mechanism, a pinch roll, an over-balanced swinging roller bed mechanism and a shear gauge. The upper and lower knife rests are arranged in the front part of the shear gauge device relatively. The shear gauge is arranged in the rear part of the shear gauge device. The shear blade clearance adjusting mechanism is installed outside the upper knife rest, the upper knife rest can be moveably arranged between the shear blade clearance adjusting mechanism and the frame, the over-balanced swinging roller bed mechanism is arranged close to the lower knife rest, and the frame consists of two integrally cast and formed vertical plates which are oppositely arranged. Tool changing windows which are circumferentially closed are arranged in positions corresponding to an upper blade of the upper knife rest and a lower blade of the lower knife rest on the surface of the vertical plates. The rotary cutting type cut-to-length device for the plate of moderate thickness provided by the invention has the advantages of strong rigidity and small deformation of the frame, high shearing quality, good lubricating effect, avoids mutual shearing of the upper and lower shear blades and can recycle the lubricating oil.
