Technical field
The present invention relates to a kind of curve lace blanking units.
Background technology
Edger is the edge utilizing punch trimming process part processing, makes it have the diel of certain altitude, diameter and shape.Edger is mainly used in the edge repairing drawing part, makes end face smooth attractive in appearance, is convenient to next step assembling.The fields such as edger is widely used in machine-building, auto parts are produced, beverage bottle is processed, fastener mold is supporting.
At present, for kettle class part, the shape due to Hu Kou is curve-like, and shape is comparatively complicated, therefore, adopts conventional mould to be difficult to carry out die-cut to it, thus, needs a kind of new die cutting die to carry out the die-cut of surface curve class workpiece.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of curve lace blanking units, the present invention can fast and accurately carry out die-cut to the lace of the workpiece with curve.
Technical scheme of the present invention is as follows:
Curve lace blanking units, comprise upper bolster, punch, stripper, die, die socket, base and wedge, one end of punch is fixed on the lower surface of upper bolster, the periphery of the other end of punch is provided with the first arc-shaped recess, described stripper is provided with through hole, stripper is enclosed within punch, the lower surface of stripper is provided with the second arc-shaped recess, the camber line of 90 degree is formed after this second arc-shaped recess is connected with the first arc-shaped recess, described die is positioned at immediately below punch, die is provided with through hole, the surface of this through hole is arcwall face, the radian of this arcwall face is 90 degree, die is fixed on die socket, die socket is slidably fitted on base, die socket is also provided with back-moving spring, die socket is provided with hole, one end of described wedge is fixedly connected with upper bolster, the other end of wedge is positioned at the top in the hole on die socket.
Also comprise a reinforcing ring, this reinforcing ring is looped around around stripper, and reinforcing ring is fixedly connected with upper bolster by screw.
Also comprise a rubber blanket, this rubber blanket is clamped between upper bolster and stripper.
Have employed such scheme, when upper bolster drives patrix up-downgoing, the inclined-plane of wedge first promotes die socket and die fixed thereon moves right together along guide pillar.After die left and right two parts are merged together, patrix continues descending, and reinforcing ring is inserted in die.Patrix is descending again, stripper workpiece pressing, and and then punch is descending die-cut, is cut out by curve lace.When slide block is with patrix backhaul, reinforcing ring first departs from die, and wedge is with backed off after random.At this moment die is together with the left-half of die socket, under the return active force of left back-moving spring, die socket is resetted.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
See Fig. 1 and Fig. 2, curve lace blanking units of the present invention, comprise upper bolster 3, punch 4, stripper 6, die 8, die socket 9, base 10 and wedge 2, one end of punch 4 is fixed on the lower surface of upper bolster 3, and the periphery of the other end of punch 4 is provided with the first arc-shaped recess 1.Described stripper 6 is provided with through hole, and stripper 6 is enclosed within punch, and the lower surface of stripper 6 is provided with the second arc-shaped recess 5, and this second arc-shaped recess 5 is connected the camber line of rear formation 90 degree with the first arc-shaped recess 1.Described die 8 is positioned at immediately below punch 4, and die 8 is provided with through hole, and the surface of this through hole is arcwall face, and the radian of this arcwall face is 90 degree.Die 8 is fixed on die socket 9, and die socket 9 is slidably fitted on base 10, and base 10 is provided with guide pillar 11, and die socket 9 is provided with chute, and die socket 9 and guide pillar 11 are slidably matched.Die socket is also provided with back-moving spring 12, and when die socket 9 whole slide, back-moving spring 12 is compressed, and die socket 9 is after losing thrust, and die socket 9 resets under the return action power of back-moving spring.Die socket 9 is provided with hole, and one end of described wedge 2 is fixedly connected with upper bolster 3, and the other end of wedge 2 is positioned at the top in the hole on die socket 9.Also comprise a reinforcing ring 7, this reinforcing ring 7 is looped around stripper 6 around, and reinforcing ring 7 is fixedly connected with upper bolster 3 by screw.Also comprise a rubber blanket 13, this rubber blanket 13 is clamped between upper bolster and stripper.
The course of work of the present invention is: when upper bolster 3 drives patrix up-downgoing, and the inclined-plane of wedge 2 first promotes die socket 9 and die 8 fixed thereon moves right together along guide pillar 11.After die left and right two parts are merged together, patrix continues descending, and reinforcing ring 7 is inserted in die.Patrix is descending again, stripper 6 workpiece pressing 14, and and then punch 4 is descending die-cut, is cut out by curve lace.When slide block is with patrix backhaul, reinforcing ring 7 first departs from die, and wedge is with backed off after random.At this moment die is together with the left-half of die socket, under the return active force of left back-moving spring 12, die socket 9 is resetted.
