Description

The cutting mechanism of smashing machine for board rolling
Technical field
The utility model belongs to the auxiliary equipment of metallurgy strip rolling, particularly the cutting mechanism of smashing machine for a kind of board rolling.
Background technology
In the operation of rolling of strip structural section, the Strip of rolling need to carry out trimming, and the limit portion scaling off is called cutting edge, and cutting edge generally has two kinds of processing modes: a kind of is with crimping machine, cutting edge is curling, forms the form of an axle or a volume; Another kind is with smashing machine, cutting edge to be cut and is cut into segment form, recycles.
Smashing machine mainly adopts double drum type smashing machine at present, on double drum type smashing machine, there are two round rollers in relative rotation, shear knife is all installed in round roller, therefore round roller is called again cutter shaft, the shear knife of two cutter shafts is overlapping relative as scissors, the adjustment of the sideshake of two shear knives is extremely important, and difficulty is also very large.Upper and lower shear knife sideshake is excessive too smallly all can strengthen shearing force, makes shear knife quick abrasion, the phenomenon that even there will be to fall sword, collapses piece.
For this reason, Chinese patent ZL20132002456.6 discloses a kind of board rolling smashing machine, it mainly comprises frame, transmission system, cutting mechanism and opening degree adjusting device, transmission system is mainly comprised of drive motors, decelerator, power transmission shaft, drive motors is located at one end of frame, and this drive motors is passed to power transmission shaft by decelerator power; Two cutting mechanism is symmetrical, structure is identical, be located at respectively on the guide rail in frame, cutting mechanism is mainly comprised of casing, cutter shaft, compression spring, bolt, shear knife, shear plate and gripper shoe, cutter shaft is provided with internal spline, above-mentioned power transmission shaft is provided with external splines, and cutter spindle sleeve, on power transmission shaft, forms spline coupling, above-mentioned power transmission shaft drives the cutter shaft in two cutting mechanisms to rotate, and power transmission shaft and cutter shaft can mutually move axially to adapt to different openings degree and shear.One end of cutter shaft is provided with 2-4 cutter groove, and 2-4 shear knife is arranged in cutter groove by bolt and compression spring, and shear knife is helical edges, gripper shoe is fixed on casing, it is corresponding with shear knife below cutter shaft, and this gripper shoe is provided with shear plate, and shear plate adopts the low and wear-resisting material of hardness.Opening degree adjusting device is mainly comprised of buncher and leading screw, buncher is located at the other end of frame, buncher drives leading screw to rotate, and the casing of above-mentioned cutting mechanism is provided with screwed hole, and above-mentioned leading screw drives two cutting mechanisms to slide on the guide rail of frame by spiral marking connection.
The main feature of the cutting mechanism of ZL20132002456.6 patent documentation is to adopt spiral helicine shear knife, and in the two ends of spiral shear cutting knife, cutter groove below shear knife, adopt helical spring to withstand shear knife, for shear knife provide with gripper shoe on the pressure of shear plate.The spring of this cutting mechanism is the two ends that are supported on shear knife, and the stage casing of shear knife is unsettled, the width of the cutting edge simultaneously scaling off from steel plate or steel band is also irregular, cutting edge arrive cutting mechanism up and down between cutter shaft time, position between upper and lower cutter shaft is also unfixed, when cutting edge is narrower and be positioned at the stage casing of shear knife, only the stage casing of shear knife is produced to drag, make to occur bending and deformation in the middle of shear knife, and the fragile material that shear knife is all generally high rigidity is made, this distortion can make shear knife break; Even if shear knife can not break, and be only crooked, may can't cut cutting edge, and not reach the effect of smashing machine.
Utility model content
The utility model technical issues that need to address are to provide a kind of smashing machine cutting mechanism that can improve chopping effect, prevent shear knife fracture.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
The cutting mechanism of smashing machine for board rolling, comprise casing, the quill that power transmission shaft is installed in casing and is slidably matched by spline with power transmission shaft, the end of the quill of casing outside is upper cutter shaft, on upper cutter shaft, shear knife is installed, in the correspondence of casing outside, the position of cutter shaft shear knife is provided with gripper shoe, above gripper shoe, be mounted with shearing copper coin, described shear knife is that straight knife and cross section are L-type, shear knife is along the axial setting of upper cutter shaft, shear knife is that the bolt by two ends is movably connected in the cutter groove of upper cutter shaft, two leads that bolt moves up and down as shear knife, the snug engagement of the side of shear knife and cutter groove, at cutter trench bottom, below shear knife, between two bolts, be placed with elongated leaf spring, described leaf spring is M template spring or Z-shaped plate spring.
Further improvement of the utility model is: the cross section of described M template spring is M type, and M template spring button is put or faced upward in the cutter groove bottom that is placed on cutter shaft; The longitudinal length of leaf spring is between two bolts.
Further improvement of the utility model is: the cross section of described Z-shaped plate spring is Z-type, and Z-shaped plate spring is erect and is supported between the cutter groove bottom of shear knife and upper cutter shaft, and the longitudinal length of leaf spring is between two bolts.
Shear knife on above-mentioned upper cutter shaft can arrange 2~4 roads, shears copper coin and can also adopt the lower and wear-resisting material of other hardness.
Owing to having adopted technique scheme, the technological progress that the utility model is obtained is:
In the cutter groove of the upper cutter shaft of the utility model below shear knife, be provided with the leaf spring that connects shear knife length direction, leaf spring supports the mid portion of shear knife, the cutting edge of pipe plate where contacting with shear knife at shear knife not, shear knife is all whole stressed, shear knife can not produce flexural deformation, whole blade can contact with shearing copper coin integral body, not only can improve chopping effect, but also can prevent shear knife fracture.The utility model only has upper cutter shaft to establish shear knife simultaneously, compare with traditional scrap cutter mechanism, there is not the problem of two sideshake sizes between shear knife, eliminated the technical problem that sideshake is brought, also needn't adopt the subdivision gear relevant to sideshake, high-precision bearing and axial-adjustment unit, reduce cost.
The utility model by leaf spring be arranged on shear knife below, between two bolts, leaf spring not only can reduce shear knife and shear the rigid shock of copper coin, but also can control tightness degree and the strength size that shear knife contacts with shearing copper coin by the leaf spring of the leaf spring with different size, different elastic force, by adjusting shearing force size, adapt to the steel plate of different hardness or the sheared edge of steel band.In work, upper cutter shaft rotates, and shear knife periodically contacts with shearing copper coin, and Strip cutting edge is cut off, and the distance that the dynamics that shear knife contacts with shearing copper coin can also be sheared between copper coin and upper cutter shaft by adjustment regulates shearing force size.After working long hours, if shear the larger local tool marks of copper coin generation, only need suitably to adjust the relative position of shearing copper coin and upper cutter shaft, just can again guarantee shear knife and shear the tightness degree that copper coin contacts, improve the performance of shearing, easy to operate.The utility model is compared with traditional smashing machine cutting mechanism, only has upper cutter shaft to rotate, and has omitted the driving parts such as all a plurality of gears, axle and bearing.
