Detailed description of the invention

Below, by reference to the accompanying drawings and detailed description of the invention, the present invention is described further:

As shown in figures 2-6, be the syndeton of cutting die of the present invention and cutter shaft, comprise cutting die 30, the cutter shaft 40 in hollow form, driver part 20, pull bar 10; The lower end of described cutter shaft 40 is provided with location division 50; Described cutting die 30 comprises cutting die plate 31, the cutting knife 32 be connected on cutting die plate 31; Described cutting die plate 31 offers the locating hole 33 for location division 50 setting-in; Described location division 50 is provided with the central through hole with cutter shaft 40 cavity connects; Several joint-cuttings 51 are shown around the central axis circumferential row of cutter shaft 40 in described location division 50; Each joint-cutting 51 all extends inwardly to its medial surface from location division 50 lateral surface, and location division 50 is divided into by each joint-cutting 51 base portion 52 that several medial extremitys are connected with cutter shaft 40; Described pull bar 10 is movably arranged in cutter shaft 40, and drives pull bar 10 moving axially along cutter shaft 40 by driver part 20; The lower end of described pull bar 10 is connected with when being positioned at central through hole inside for by each base portion 52, towards making away from cutter shaft 40 central axial direction pushing tow, the inner hole wall of location division 50 lateral surface and locating hole 33 is friction tight struts portion 60.Wherein, in the present embodiment, this location division 50 is inner side near the side of cutter shaft 40 central axis, and the side away from cutter shaft 40 central axis is outside.

In connection procedure, first location division 50 is inlaid in locating hole 33, then driver part 20 is started, driver part 20 works and struts portion 60 by pull bar 10 drive and moves up, and when strutting portion 60 and moving to the central through hole inside of location division 50, by each base portion 52 towards away from cutter shaft 40 central axial direction pushing tow with the inner hole wall tight fit of the lateral surface and locating hole 33 that make location division 50, thus the connection of cutter shaft 40 and cutting die 30 can be realized.And in unloading process, driver part 20 struts portion 60 by pull bar 10 drive and moves down, and away from location division 50, now, the thrusting action power strutting the 60 pairs of base portions 52 in portion is cancelled, and location division 50 can be shifted out in locating hole 33, thus can realize the dismounting of cutter shaft 40 and cutting die 30 easily.

The present invention struts portion 60 by each base portion 52 towards away from cutter shaft 40 central axial direction pushing tow by utilization, the lateral surface of location division 50 and the locating hole 33 inner hole wall tight fit of cutting die 30 can be made, to realize the connection of cutter shaft 40 and cutting die 30, thus, the size of cutting die plate 31 can set according to the size of material to be cut, and set without the need to the size according to card holding trough, effectively can reduce the sheet material consumption of cutting die plate 31, reach the object of saving resource; And, only utilize driver part 20 driving to strut portion 60 and move up and down, just can realize the clamping of location division 50 and locating hole 33, unclamp, thus make cutter shaft 40 comparatively simple and convenient with the dismounting of cutting die 30; And, being connected firmly of cutter shaft 40 and cutting die 30, stable, be conducive to promoting.

Preferably, each joint-cutting 51 all extends upwardly to the circumferential wall of cutter shaft 40 from the lower surface of location division 50.And by joint-cutting 51 being extended upwardly to the circumferential wall of cutter shaft 40, the amplitude that base portion 52 struts can be increased.

Preferably, the cross section of described locating hole 33 is polygon, and the cross section of described location division 50 and the cross section of locating hole 33 match.By utilizing the restriction of locating hole 33 and location division 50, cutting die 30 can be rotated along with cutter shaft 40.

Preferably, the rectangular in cross-section of described locating hole 33.And by adopting said structure, processing can be convenient to.

Preferably, described driver part 20 is fixed on the cylinder on cutter shaft 40 upper end for cylinder body; Described pull bar 10 is connected on the piston rod of cylinder.And by adopting said structure, assembling can be convenient to, to be conducive to reducing assembly cost.

Preferably, portion 60 is strutted described in up-small and down-big taper.And by adopting said structure, when strutting portion 60 and being moved upward to the central through hole of location division 50 gradually, location division 50 progressively can be strutted, to reduce probability base portion 52 being caused to damage.

Preferably, described cutting die plate 31 is plank.Concrete, the inner hole wall of described locating hole 33 tilts towards near the direction of locating hole 33 center line gradually from upper end to lower end, and the bearing of trend of described locating hole 33 center line is consistent with the short transverse of cutting die plate 31.Because the lateral surface of each base portion 52 is all in heeling condition when softened state under effect of stress, and by rationally arranging the inner hole wall of locating hole 33, the fiting effect of location division 50 and cutting die plate 31 can be improved.

To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the claims in the present invention.
