The upper die plate and the lower die plate are connected through the guide pillars; the female die is arranged on the lower die plate, and the male die component is arranged under the upper die plate through the symmetric connecting pillars; the driving device is further arranged under the upper die plate and connected with the male die component; straight slots enabling the male die component to pass through are arranged in the lower die plate and the female die; the male die component is of an integral structure comprising a male die and a boss; the section of the male die is an isosceles trapezoid; an included angle between two oblique edges of the isosceles trapezoid is 90 degrees; the boss is arranged on the outer side face of the female die; the bottom surface of the boss is located under the bottom surface of the male die; the outer side face of the boss is flush with the outer side walls of the straight slots; the positioning block is arranged on the female die. The support punching device is used for punching angle steel small in size and is high in punching precision and punching efficiency, and punching quality is improved.
Description
Technical field
The present invention relates to a kind of blanking units, particularly a kind of support blanking units used in making pony support process.
Background technology
When making support as described in Figure 1, comprise the processing step that a following step is die-cut, namely on the angle steel 11 shown in accompanying drawing 2, the breach 12 of die-cut 2 isosceles trapezoid shape.In order to make clicking technique quick, carrying out accurately, needing to use die cutting die.Diel is in the past simpler and easy, but die-cut accuracy is not high, and the quality of die-cut technique directly affects the carrying out of lower step process, if when the stent size made is less, then needs to design a kind of die-cut accurate blanking units.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose the high and support blanking units that die-cut efficiency is high of a kind of die cutting accuracy.
Technical solution of the present invention is achieved in that a kind of support blanking units, comprises cope match-plate pattern, lower bolster, guide pillar, die, joint pin, punch assemblies, drive unit and locating piece; Described cope match-plate pattern is connected by guide pillar with lower bolster; Described lower bolster is provided with die; The below of described cope match-plate pattern is provided with punch assemblies by symmetrically arranged joint pin; The below of described cope match-plate pattern is also provided with drive unit; Described drive unit is connected with punch assemblies; Described lower bolster and die have the groove that punch assemblies is passed through; Described punch assemblies is the integral structure comprising punch and boss; The cross section of described punch is isosceles trapezoid; Two waist angles of described isosceles trapezoid are 90 °; Described boss be arranged on punch lateral surface; The bottom surface of described boss is positioned at the below of punch bottom surface; The lateral surface of described boss is mutually concordant with the lateral wall of groove; Described die is provided with locating piece.
Preferably, described drive unit is cylinder; Described cylinder is arranged on the below of cope match-plate pattern; The end of the expansion link of described cylinder is connected with punch assemblies.
Preferably, described cylinder is provided with two.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Support blanking units of the present invention, carries out die-cut for the angle steel less to size.Guiding and location all rely on boss, and the lateral surface of boss is mutually concordant with the lateral wall of groove, subjects the side force in blanking process, die cutting accuracy is guaranteed, improves stamping quality, and ram efficiency is high, are applicable to batch die-cut.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
Of the present invention a kind of support blanking units as shown in accompanying drawing 3,4, comprises cope match-plate pattern 1, lower bolster 2, guide pillar 3, die 4, joint pin 5, punch assemblies, drive unit and locating piece 6; Described cope match-plate pattern 1 is connected by guide pillar 3 with lower bolster 2; Described lower bolster 2 is provided with die 4; The below of described cope match-plate pattern 1 is provided with punch assemblies by symmetrically arranged joint pin 5; The below of described cope match-plate pattern 1 is also provided with drive unit; Described drive unit is connected with punch assemblies; Concrete drive unit is cylinder 7; Described cylinder 7 is arranged on the below of cope match-plate pattern 1; The end of the expansion link of described cylinder 7 is connected with punch assemblies; Described lower bolster 2 and die 4 have the groove 8 that punch assemblies is passed through; Described punch assemblies is the integral structure comprising punch 9 and boss 10; The cross section of described punch 9 is isosceles trapezoid; Two waist angles of described isosceles trapezoid are 90 °; Described boss 10 be arranged on punch 9 lateral surface; The bottom surface of described boss 10 is positioned at the below of punch 9 bottom surface; The lateral surface of described boss 10 is mutually concordant with the lateral wall of groove 8; Described die 4 is provided with locating piece 6.
Of the present invention a kind of support blanking units as shown in Figure 5, during use, needs die-cut face to be placed on die 4 by angle steel 11, another side is then near locating piece 6, open cylinder 7, the expansion link of cylinder 7 stretches out, and drives punch assemblies descending, the lateral surface of boss 10 is mutually concordant with the lateral wall of groove 8, boss 10 plays the effect of guiding and location, subjects the side force in blanking process, the die-cut angle steel 11 of punch 4 simultaneously, punch out breach, waste material then spills from groove 8; After one-step punching terminates, the expansion link of cylinder 7 is regained, and drive punch assemblies to get back to initial position, so repeatedly die-cut, die-cut efficiency is high.
Support blanking units of the present invention, carry out die-cut for the angle steel less to size, die cutting accuracy is high, improves stamping quality, and ram efficiency is also high, is applicable to batch die-cut.
Above-mentioned support blanking units, described cylinder is provided with two and makes, and die-cut effect reaches optimization.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
