Summary of the invention
The object of invention is to provide that a kind of cost is low, machining accuracy is high and the magnetic conduction sheet blanking die of the difficult phenomenon that gets stuck.
In order to achieve the above object, the technical scheme that invention adopts is as follows:
A kind of magnetic conduction sheet blanking die, comprise upper mould device and lower mold apparatus, described upper mould device comprises die shank, cope match-plate pattern, outer guiding post, upper padding plate, fixed head and punch, described die shank is installed on cope match-plate pattern, described cope match-plate pattern is installed on lower mold apparatus by outer guiding post is liftable, described upper padding plate is installed on the lower end of cope match-plate pattern, and described fixed head is installed on the lower end of upper padding plate, and described punch is installed on the lower end of upper padding plate through fixed head; Described lower mold apparatus comprises die and lower bolster, and described die is installed on lower bolster and is corresponding with punch, and the diameter of described die is greater than the diameter of punch; This mould also comprises and being installed on lower bolster for regulating the governor motion of die horizontal displacement, and is located at die upper end for take off the material removing mechanism of material after punch is with respect to die punching press.
Preferably, described for regulating the governor motion of die horizontal displacement to comprise to be installed on lower bolster and be positioned at the adjusting ring in die outside, and be installed on a plurality of adjustment screw on adjusting ring circumferencial direction.
Preferably, described material removing mechanism comprises the guide plate that is installed on adjusting ring upper end, and this guide plate is positioned at the upper end of die, and is also provided with the guide hole corresponding with punch on this guide plate.
Compared with prior art, the advantage of invention is: one aspect of the present invention adopts governor motion to regulate the horizontal displacement of die, can make the gap between die and punch even, to improve section fineness and the precision of stamping-out magnetic conduction sheet, adopt on the other hand material removing mechanism after punch is with respect to die punching press, to take off material, stuck technical problem while having avoided patrix discharging.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, invention is described further.

Description of reference numerals: 1, die shank, 2, cope match-plate pattern, 3, outer guiding post, 4, upper padding plate, 5, fixed head, 6, punch, 7, stamping-out plate, 8, guide plate, 9, die, 10, adjusting ring, 11, lower bolster, 12, adjustment screw.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be described in further detail.
Consult shown in Fig. 1-Fig. 2, a kind of magnetic conduction sheet blanking die that invention provides, comprise upper mould device and lower mold apparatus, wherein, upper mould device comprises die shank 1, cope match-plate pattern 2, outer guiding post 3, upper padding plate 4, fixed head 5 and punch 6, and die shank 1 is installed on cope match-plate pattern 2, cope match-plate pattern 2 is installed on lower mold apparatus by outer guiding post 3 is liftable, upper padding plate 4 is installed on the lower end of cope match-plate pattern 2, and fixed head 5 is installed on the lower end of upper padding plate 4, and punch 6 is installed on the lower end of upper padding plate 4 through fixed head 5; And lower mold apparatus comprises die 9 and lower bolster 11, die 9 is installed on lower bolster 11 and is corresponding with punch 6, and the diameter of die 9 is greater than the diameter of punch 6; This mould also comprises and being installed on lower bolster 11 for regulating the governor motion of die 9 horizontal displacements, and is located at die 9 upper ends for take off the material removing mechanism of material after punch 6 is with respect to die 9 punching presses.Like this, one aspect of the present invention has adopted governor motion to regulate the horizontal displacement of die 9, can make the gap between die 9 and punch 6 even, to improve section fineness and the precision of stamping-out magnetic conduction sheet, adopt on the other hand material removing mechanism to take off material after punch 6 is with respect to die 9 punching presses, stuck problem while having avoided patrix discharging.
Concrete, for regulating the governor motion of die 9 horizontal displacements to comprise to be installed on lower bolster 11 and be positioned at the adjusting ring 10 in die 9 outsides, and be installed on a plurality of adjustment screw 12 on adjusting ring 10 circumferencial directions.And, die 9 and adjusting ring 10 are all arranged on lower bolster 11 by screw, and screw hole on screw and die 9, and and adjusting ring 10 on screw hole between all there is gap, like this, when regulating adjustment screw 12, can make the side of the end conflict die 9 of adjustment screw 12, and then make die 9 do in the horizontal direction the fine setting of displacement.
Concrete, above-mentioned material removing mechanism comprises the guide plate 8 that is installed on adjusting ring 10 upper ends, this guide plate 8 is positioned at the upper end of die 9, and is also provided with the guide hole corresponding with punch 6 on this guide plate 8, and guide plate 8 need to adopt the material of rigidity.Be punch 6 after the descending stamping-out of the guide hole through guide plate 8, in up process, by guide plate 8, can, by material from gear on punch 6, solve the stuck problem of patrix discharging.
Below more by reference to the accompanying drawings 1 and Fig. 2 the operation principle of magnetic conduction sheet blanking die of the present invention is described further:
This magnetic conduction sheet blanking die of the present invention is negative clearance stamping-out (being the diameter that the diameter of die 9 is a bit larger tham punch 6), during work, mould is arranged on forcing press, during mode transfer, first by adjustment screw 12, adjusts the gap of 6 of die 9 and punch, makes it even.Thereby the slide block of forcing press drives the descending punching press stamping-out of punch 6 plate 7, can obtain the product that stamping-out section fineness and precision are higher.And when mold work, patrix carries out stamping-out action with forcing press is descending, forcing press is during to bottom dead centre, punch just thrusts product (owing to being negative clearance stamping-out, punch 6 can not enter 9 li of dies), forcing press is up, and the guide plate 8 by rigidity unloads the plates that are stuck on punch 6, forcing press is got back to top dead-centre, completes an operation cycle.
Although described by reference to the accompanying drawings working of an invention mode; but the patent owner can make various distortion or modification within the scope of the appended claims; as long as be no more than the described protection domain of the claim of invention, all should be within the protection domain of invention.
