The utility model relates to a kind of cutter, especially the cutter of steel plate or sheet metal strip.
Metal-slitting machine is widely used in longitudinal shear thickness less than 10 millimeters steel plate and strip steel, because blade is the disk of rotation, thereby the moving steel plate of longitudinal shear or be with steel continuously.On the finishing line that circle shear is provided with usually, be used for moving steel plate longitudinal edge is trimmed or be cut into ribbon steel, generally on multitool sword circle shear, carry out.Can be divided into according to the cut mode difference: the power scissors, draw scissors and hybrid three kinds of forms.When drawing scissors to be meant the circle shear feeding, circle shear is transmission, by the time coiling machine is nipped behind the ribbon steel, form coiling tension, the circle shear knife edge part just separates with transmission system, and rely on the pulling force of coiling machine to shear, circle shear in shear history by being transferred to not transmission, general adopt a kind of manual clutch, promptly after just forming coiling tension, with manual method with motor, reductor power transmission shaft and circle shear main shaft are thrown off, this method not only falls behind, and concerning the operator, there is very big danger, because action bars is after promoting the throw-out-of clutch speed reducer output shaft, sometimes because of not restoring naturally suddenly in conjunction with tight, not only circle shear is with power again, strip coiling tension force is eliminated and loose winding, and the action bars operator that can injure, even can damage this mechanism.In addition, during circle shear rip cutting band steel, be to finish by the blade rotational shear on the upper and lower main shaft.When shearing the band steel of different-thickness, the radially lap between the last bottom knife is to need to adjust, and this adjustment realizes by screw-down.The adjustment of the upper and lower main shaft of disk at present, generally all be that lower shaft is fixed, by about adjust separately and go up axle and realize, driving upward by adjustment gear and screw rod, the axle bearing seat moves up and down along the support body slideway, the shortcoming of this adjustment is: the depth of parallelism that 1. goes up lower main axis is difficult to guarantee, adjust one-shot measurement once, increased non-cutting time.2. in the shear history because gapped between screw rod and the nut, be easy to generate the little jumping of main shaft during shearing, cause the band steel shear not exclusively or burr excessive, influence shearing quality or precision.
The purpose of this utility model will provide a kind of upper and lower axle band freewheel clutch, screw-down band worm gear, worm screw, screw rod, the metal-slitting machine that wedge is arranged between upper and lower bearing block, automatically throw off when it can make motor and speed reducer power transmission shaft and circle shear main shaft differential, it is high and simple to operate to make shaft position adjust precision.
The purpose of this utility model is achieved in that is installing a freewheel clutch (18) respectively on axle (3) and the lower shaft (2) on the metal-slitting machine.Cutter screw-down (9) is fixed on active side memorial archway (4) and the transmission side memorial archway (20), transmission top box (7) is middle with transmission nowel (5) to be worm gear (16), worm screw (8), worm screw (8) axle one end fixed handle (6), the other end and drive link (11), spline housing (10) links to each other, worm gear set is on screw rod (13), screw rod is fixed on the bearing block (17) of axle (3), on, dress-wedge between the step (1), between worm gear (16) and the transmission nowel (5) butterfly spring (12) is housed, screw rod (13), between steel nut (14) and the worm gear (16) butterfly spring (15) is housed.
Freewheel clutch (18) is made up of interior cover, star-wheel, roller and overcoat etc., during the circle shear transmission, transmission side power passes to interior cover by overcoat through roller, star-wheel, drive the upper and lower axle motion of circle shear, after winding formed coiling tension, then upper and lower axle carried out the circle shear rip cutting with coiling machine pulling steel band and rotates, thereby by interior cover with overcoat in the freewheel clutch separately, make the transmission side power source ineffective, not only safe but also reliable.This freewheel clutch has one-way, promptly has only when band steel during along the correct direction rip cutting, could realize surmounting, if circle shear motor circuit connects counter-rotating on the contrary, the upper and lower axle of circle shear can be with commentaries on classics, and during the assurance on-line shearing, can not be with steel not break.
Screw-down (9) adopts worm gear (16), worm screw (8) central driving, and axle diaxon bearing (17) synchronized movement is carried out.Change single butterfly spring group into two butterfly spring groups, promptly respectively have one group to press, depress butterfly spring group, go up between screw rod and the steel nut or following sideshake, eliminate main axis jerking, improve shearing quality and precision in order to eliminate at worm gear (16) upper and lower end.
Between upper and lower bearing block, increase the wedge positioner, can further eliminate the upper and lower sideshake between screw rod and the steel nut, promptly after last axial adjustment level,, wedge is advanced between the upper and lower bearing block position by adjusting bolt, like this, shearing the same thickness steel band, needing to adjust shearing width and when changing blade, need not readjust screw-down, only need bolt is tightened, wedge advances to put in place and gets final product.
The utility model makes upper and lower axle of circle shear and transmission system separate not only safe but also reliable because upper and lower axle is installed freewheel clutch respectively.Screw-down makes the axial adjustment precision high and simple to operate owing to adopt worm and gear, can eliminate the sideshake between screw rod and steel nut, has increased the wedge location, makes things convenient for the cutting edge adjustment.
