For achieving the above object, the cylinder flying shear that the utility model provides a kind of spiral to shear, be used for the cutting band, comprise a pair of cylinder, one blade, bearing bracket stand, drum drive, each cylinder is by the rotatable support of bearing bracket stand, provide power source work by drum drive, each cylinder along drum shaft to the cylinder outer peripheral portion have a blade, blade is fixed on the cylinder, the band of being cut places between two cylinders, have a fixing spiral angle between the axis of the blade of described blade and place cylinder, and the spiral angle number of degrees between the axis of two blade place straight lines and place cylinder equate; Described two blades are mirror image and are symmetrical arranged with respect to cutting band.Owing to there is a spiral angle between two blades, one end of two blades contacts simultaneously to be cut band and begin and shears during shearing, and slightly the other end of latter two blade just begins to contact simultaneously and cut band and shear, and so far, once shears and just finishes.In this shear history, blade becomes spiral and shears, so shearing force is little when shearing, vibrate littlely, noise is low, can prolong the service life of rotary flying shears, two blades are along being cut the band plane when being mirror image and being symmetrical arranged, when shearing band, two blades are stressed evenly, improved the kerf quality of being cut band.Further, the spiral angle between the axis of described blade place straight line and place cylinder is greater than 0 °, and less than 2 °.
Further, described cylinder is provided with a spiral cutter groove, and blade is placed in the spiral cutter groove.The design spiral cutter groove is for the ease of fixed blade, and straight knife sheet strain in spiral cutter groove becomes screw blade simultaneously.
Further, the described affixed bolt connection that is.
Further, also comprise a plurality of long spiro nails, described screw passes blade and runs through cylinder, then by nut blade is fixed on the cylinder.When being cut band when thicker, when needing larger shearing force, if diameter of cylinder is less, can adopts long spiro nail to pass blade and run through cylinder, thereby blade is fixed on the cylinder.Because diameter of cylinder hour, if adopting short screw to carry out bolt connects, be subject to the less restriction in space in the cylinder, the diameter of short screw also is restricted, and causes the fastening force of screw limited, and needs larger shearing force just can finish shearing in the work, the vibration of blade is larger, short screw can't for a long time with stable being fixed on the cylinder of blade, so need to adopt long spiro nail to run through cylinder, just can be strengthened fastening force.
Further, also comprise a plurality of short screws, described screw passes blade and is fixed on the cylinder.When being cut band when thicker, if diameter of cylinder is larger, can adopt short screw that blade is fixed on the cylinder, more convenient when like this blade being installed, can save the working time.
The cylinder flying shear that a kind of spiral of the utility model is sheared has following advantage:
One, shearing force is little, vibrates littlely, and noise is low, long service life;
Two, it is good to be cut the kerf quality of band;
Three, save the working time, reduce production costs.
