High accuracy disk for strip continuous processor group as above is cut, it is characterized in that: the cutterhead assembling of described cutterhead drift angle guiding mechanism can be rotated with respect to base around rotating dog, adjusting the bolt of drift angle guiding mechanism, thereby make the left and right cutterhead form certain drift angle with the unit centre line respectively.
High accuracy disk for strip continuous processor group as above is cut, and it is characterized in that: the guiding mechanism of described up and down cutter lap moves up and down for drive ball screw assembly, driving upper tool pan by servomotor, reaches the purpose of adjusting the cutterhead lap.
High accuracy disk for strip continuous processor group as above is cut, and it is characterized in that: on the cutter shaft of described cutterhead retaining mechanism, expansion sleeve is housed, when cutterhead is changed, only need loosens the expansion sleeve bolt, can rotate and extract expansion sleeve and cutterhead out; Cutterhead after replacing is loaded onto expansion sleeve and swelling after installing, and can make cutterhead locking.
The beneficial effects of the utility model are: this novel high-precision circle shear can overcome the defective of traditional circle shear: (1) open degree adjustment mechanism pulls ball screw assembly, to drive cutterhead by reducing motor and is assemblied in side-to-side movement on line slideway, the ball screw assembly, compact conformation causes vibration in the time of avoiding shearing; (2) on gear-box, stand-by motor is installed, after the off-line tool changing, can be started stand-by motor and carry out trial cut, the effect that check is adjusted improves operating rate; (3) cutterhead can carry out the drift angle adjustment with respect to the unit centre line, reduces the band steel arching phenomenon when shearing strip; (4) adjustment of cutterhead lap is to drive ball-screw by the vertically arranged servomotor in cutterhead frame top, automatically adjusts the lap of up and down cutterhead, and realizes digital automatic control with servomotor and encoder; (5) cutterhead adopts expansion sleeve locking, and installing/dismounting is quick and easy, reliable.
Compare with traditional circle shear, that this Novel disc shear has is easy to adjust, adjust the clear superiorities such as precision is high, compact conformation is reasonable, is fit to very much finished product strip continuous processor group and uses.For some cold-strip steel move back as connecting, for degreasing, straightening, rewinding continuous-output machine group, particularly strip finishing continuous processor group, this Novel disc shear can guarantee trimming quality, enhance productivity.
