Plate and band material roll gap adjustable flattening machine

Abstract

The flattening machine for plate material possesses strong flattening capacity and wide thickness range of plate material is formed from main motor, speed-reducing machine, gear distribution box, cardan shaft, flattening machine self-body, inlet pinch rolls, outlet pinch rolls, roll-changing device, hydraulic lubricating air and water control system and electric transmission and automatic controlsystem. Its upper roll device and lower roll device are respectively equipped with motor, worm speed reducer, screw rod and nut, and the inlet side, outlet side, transmission side and roll-changing side of upper roll device are respectively equipped with downward cylinder, and their pinch rolls are respectively equipped with hydraulic cylinder, motor and speed reducer.

Description

technical field [0001] The invention relates to a variable roller distance straightening machine used for straightening plate and strip in metallurgical machinery or other industries. Background technique [0002] At present, the straightening machines for plate and strip at home and abroad, especially medium and thick steel plates (thickness 4-60mm) are constant roll distance or double constant roll distance straightening machines, and have not found the same principle and structure as the present invention. Or the literature report of the similar sheet and strip material variable roll distance straightening machine. The disadvantage of the constant roller distance straightening machine is that the roller distance cannot change with the thickness and strength of the straightening plate and strip. In this way, either the strength of the roller system and the transmission device is weak, or the thickness and strength of the straightening plate and strip are limited. , The st...

Problems solved by technology

The disadvantage of the constant roller distance straightening machine is that the roller distance cannot change with the thickness and strength of the straightening plate and strip. In this way, either the strength of the roller system and the transmission device is weak, or the thickness and strength of the straightening plate and strip are limited. , the straightening ability of the straightening machine cannot be brought into full play, or two straightening machines are installed to straighten plates and strips with different thickness ranges
