Detailed description of the invention
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
Fig. 1, Fig. 2, Fig. 3 and Fig. 4 are shown a kind of sheet material slitting mill provided by the invention, comprise the upper eccentric roller 3 and lower eccentric roller 4 that installing rack 2 relatively rotate setting, installing rack 2 is arranged on base 1, and upper eccentric roller 3, lower eccentric roller 4 are all provided with bearing with the installation site of installing rack, make the rotation of eccentric roller 3 and lower eccentric roller 4 more flexible.Described upper eccentric roller 3 offers relative breach 31 with on the roll body of lower eccentric roller 4, and breach 31 place is installed with blade 12, by relatively rotating of upper eccentric roller 3 and lower eccentric roller 4, can move forward by guiding sheet metal, wherein sheet material is non-ferrous metal thin, simultaneously when the blade 12 on upper eccentric roller 3 and lower eccentric roller 4 turns to the position to cutting, steel band is directly cut off by blade 12, and this device is that sheet material between 0.7mm ~ 4mm is sheared for thickness.
Preferably, the longitudinal section of described upper eccentric roller 3 and lower eccentric roller 4 is cam-like, make eccentric roller 3 and lower eccentric roller 4 when rotating, the shearing inertia that eccentric roller 3 and lower eccentric roller 4 can be utilized to produce in rotation process, improves the shear effect of sheet material and the property passed through; Breach 31 is perpendicular type, makes blade 12 when mounted, and the surface of blade 12 is directly fitted on the surface of breach 31.
Preferably, the breach 31 on described upper eccentric roller 3 and lower eccentric roller 4 is all opened on dome, makes blade 12 be arranged on the dome of eccentric roller 3 and lower eccentric roller 4; Breach 31 axially runs through along the roll body of upper eccentric roller 3 and lower eccentric roller 4, blade 12 can be arranged on upper eccentric roller 3 and the axial corresponding position of lower eccentric roller 4, can install the blade 12 of different length.
Preferably, blade 12 cutting edge on described upper eccentric roller 3 and lower eccentric roller 4 is all corresponding on the center line of roll body, makes eccentric roller 3 and lower eccentric roller 4 in rotation process because the shearing of the effect of self gravitation to steel band is assisted.
Preferably, the homonymy of described upper eccentric roller 3 and lower eccentric roller 4 is provided with pitch wheel 6, and the number of teeth of two gears 6 is equal, makes eccentric roller 3 and lower eccentric roller 4 synchronous in rotation process, make the shearing of steel band convenient, the position of shearing is more accurate.The rotating shaft of one of them gear 6 is simultaneously connected with gearbox 8 by shaft coupling 7, and gearbox 8 is connected with the main shaft of drive motors 9 by shaft coupling 7, first the rotation of drive motors 9 is slowed down by gearbox 8, thus realize relatively rotating of upper eccentric roller 3 and lower eccentric roller 4.
Preferably, breach 31 surface on described upper eccentric roller 3 and lower eccentric roller 4 all offers the draw-in groove 32 run through vertically, by draw-in groove 32, the side of blade 12 is stuck in draw-in groove 32, avoids blade 12 in long-term shear history medium dip, blade 12 is played and corrects and firm effect.And the another side of breach 31 offering the fixing hole 34 run through, fixing hole 34 is screwed hole, and fixing hole 34 is installed by screw and screwed hole 34 pairs of blades 12 and fixed.
Preferably, draw-in groove 32 bottom land on described upper eccentric roller 3 and lower eccentric roller 4 all offers the adjustment hole 33 vertically running through roll body, and adjustment hole 33 is counter sink; Adjustment screw is provided with in described adjustment hole 33, adjustment screw is sunk screw, and the lower surface of adjustment screw contacts with blade face, tightening and loosening by adjustment screw in adjustment hole 33, finely tunes the shear gap of upper eccentric roller 3 and lower eccentric roller 4 cutter 12 cutting edge.
Preferably, the fixing hole 34 on described upper eccentric roller 3 and lower eccentric roller 4 and adjustment hole 33 are all arranged along the axial uniform intervals of roll body, make the installation of blade 12 more stable, stressed more even in shear history; More even when making the fine setting of blade 12 simultaneously, the cutting edge of blade 12 is positioned in same level.
Preferably, described in be positioned at installing rack 2 feed side and be provided with guide plate 5, the trend of guide plate 5 pairs of sheet materials guides, and avoids because sheet material causes the clipped position of sheet material to tilt in the medium dip of advance process; And the surface of guide plate 5 is lower than the peak of lower eccentric roller 4, by the steel band transmitting device of installing rack 2 both sides, make steel band not contact guide plate 5 as much as possible in the process sheared, reduce contact and the friction of sheet material and guide plate 5.The downward-sloping bending of feed end of guide plate 5 is arranged, and avoids because steel band contacts with the entrance point of guide plate 5 and is scratched by steel band.
