The system is used for adjusting the side clearance between the shear blades of the precision circle shear. A shearing mechanism is arranged on a cutter shaft system. The front portion of the cutter shaft system is arranged in a cutter box in a sleeved mode through a cylindrical roller bearing. The rear end of the cutter shaft system is arranged in a sliding bearing block through a pair of angular contact bearings in a sleeved mode. The sliding bearing block is arranged in the cutter box and is connected with a lead screw adjusting assembly which is connected with a fixed disk in a threaded mode. One end face of the fixed disk is connected with the end face of the cutter box. The other end face of the fixed disk is connected with one end face of a slowdown motor which is connected with the lead screw adjusting assembly through flat keys. The other end face of the slowdown motor is connected with an encoder seat. An encoder is arranged on the encoder seat and is connected with the lead screw adjusting assembly through a sliding coupler.

Description
Technical field
The present invention relates to iron and steel and non-ferrous metal industry technical field, is a kind of for precision adjustment rotary shear equipment cutting edge side clearance system specifically.
Background technology
Circle shear, is widely used at iron and steel and non-ferrous metal industry to shearing equipment as the accurate continuous vertical of sheet metal strip.The primary structure of circle shear has cutting mechanism, cutting edge overlap adjusting system, cutting edge side gap adjusting mechanism, girff open degree adjustment mechanism etc.Cutting edge side gap adjusting mechanism is as one of core component of circle shear work, and rotary shear equipment will be adjusted corresponding side clearance between cutter and bottom knife according to different strip thickness at work, thereby guarantees final strip shearing quality.
In prior art, the side gap adjusting mechanism of circle shear is generally to adopt screw mechanism or Wedge mechanism.Screw mechanism is the adjustment to upper cutter shaft or lower cutter shaft by screw mandrel, after being transferred to position, cutting edge side clearance by manual type, carries out nut check again, thereby in assurance circle shear shearing process, cutting edge side clearance is stable, and shortcoming is to realize automatic adjusting, and automaticity is low.Oblique wedge adjustment mechanism is that the rectilinear motion on the identical wedge of gradient is realized the adjustment to cutting edge side clearance by the line slideway in cutter shaft vertical direction, consider the stability in adjustment process, even gradient is less generally to make the wedge of 1:40, so just the adjusting range of lap is restricted, can not realize the shearing to large span strip, especially the shearing of slab, simultaneously, line slideway is difficult to guarantee to the stability of shearing, have influence on strip shearing quality, later maintenance expense is corresponding increase also.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present invention is to provide a kind of accurate circular disc shear edge side gap automatic adjustment system, realize the High Precision Automatic accurate adjustment location of disc shear edge, meet the instructions for use of cutting of circle shear cutting plate band large span, also reach the object that improves the long-term stability of using of circle shear and shear the structural compactness of body.
For achieving the above object, the present invention includes and comprise and being supported in girff Ti Nei duct and axially movable cutter shaft system, it is characterized in that: cutting mechanism is arranged in cutter shaft system, the front portion of cutter shaft system is sleeved in girff body inner duct through cylinder roller bearing, the rear end of cutter shaft system is sleeved on plain bearing housing endoporus through pair of horns contact bearing, can be in girff body inner duct in axial sliding plain bearing housing be contained in the inner duct of girff body, plain bearing housing is connected with adjustment screw component, adjusting screw component and fixed disk is threaded connection, one end face of fixed disk connects girff body end face, the other end of fixed disk connects an end face of reducing motor, reducing motor is connected with adjustment screw component by flat key, the other end of reducing motor connects encoder seat, encoder is arranged on encoder seat, encoder is connected with adjustment screw component by slip coupling, adjust between screw component and fixed disk anti-backlash mechanism is housed.
Body of the present invention detects by encoder, reducing motor is realized the automatic adjustment of blade side clearance by adjusting the rotation of screw component, by threaded screw rod, adjust cutting edge side clearance, the side clearance adjusting range of cutting edge is increased, by the anti-backlash mechanism between fixed disk and adjustment screw component, can eliminate the error in blade side clearance adjustment process, realized the adjustment of blade side clearance real-time high-precision, by anti-backlash mechanism, eliminate in real time the thread pitch of adjusting between screw component and fixed disk, guaranteed the stability of circle shear in shear history, improved strip shearing quality, improved the service life of blade.
The present invention compared with prior art, automatic, real-time, the high accuracy adjustment of circular disc shear edge side gap have been realized, while having broken automatic adjustment at present, to the little restriction of shear plate tape thickness scope, improved the shearing quality of rotary shear equipment strip within the scope of large span strip; Anti-backlash mechanism installation and debugging are convenient and reliable, and encoder detects more can realize automation and intellectuality, have install and use convenient, working stability is reliable, non-maintaining feature.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, cutting mechanism 11 is arranged in cutter shaft system 9, the front portion of cutter shaft system 9 is sleeved in the inner duct of girff body 7 through cylinder roller bearing 10, cutter shaft system 9 rear ends are sleeved on plain bearing housing 8 endoporus through pair of horns contact bearing 6, cutter shaft system 9 can move backward through inner ring and the realization of the dislocation between outer ring of cylinder roller bearing 10, plain bearing housing 8 is arranged in the inner duct of girff body 7, plain bearing housing 8 can endwisely slip in girff body 7 inner ducts, plain bearing housing 8 is connected with adjustment screw component 5, adjusting screw component 5 is threaded connection with fixed disk 4, one end face of fixed disk 4 connects girff body 7 end faces, the other end of fixed disk 4 connects reducing motor 3, fixed disk 4 is threaded connection adjusts screw component 5, reducing motor 3 is connected with adjustment screw component 5 by flat key 13, the other end of reducing motor 3 connects encoder seat 12, encoder 1 is arranged in encoder seat 12, encoder 1 is being connected with adjustment screw component 5 by slip coupling 2, adjust between screw component 5 and fixed disk 4 anti-backlash mechanism 14 is housed, on the axle of anti-backlash mechanism 14 with spring.
These new practical reducing motor 3 rotations are given transmission of torque to adjust screw component 5 by flat key 13, adjust screw component 5 rotates in fixed disk 4 screwed holes, adjust rotatablely moving of screw component 5 and by plain bearing housing 8, be converted to the rectilinear motion of cutter shaft system 9, the moving forward and backward drive cutting mechanism 11(cylinder blade that seesaws of cutter shaft system 9), in the situation that another cylinder blade is axially relatively static mutually, realized the adjustment of circular disc shear edge side gap.
