Preferably, described guide post has 4, is separately positioned on corner.
Preferably, the lower surface of described bending punch is lower than the lower surface of trimming punch.
Preferably, described trimming punch is bent limit trimming punch.
Preferably, rectangular U-shaped of described locating piece.
Preferably, the left side edge of described die is within the scope of row's slug hole.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Blanking curved mould of the present invention, structure is simple, easy to operate, safe and reliable, and because stamping-out, distortion two procedures once complete, and can get rid of waste material in time, formation efficiency is high.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the workpiece schematic diagram after machining;
Accompanying drawing 2 is the blanking curved mode structure schematic diagram that working (machining) efficiency of the present invention is high;
Accompanying drawing 3 is the top view of lower die structure in the present invention;
Wherein: 1, punch rod; 2, cope match-plate pattern; 3, lower bolster; 4, guide post; 5, spring; 6, trimming punch; 7, holding pad; 8, bending punch; 9, push rod; 10, returning spring; 11, die; 12, workpiece; 13, upper limit post; 14, lower limit post; 15, locating piece; 16, slug hole is arranged.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
The high blanking curved mode structure of working (machining) efficiency of the present invention, as shown in accompanying drawing 2,3, comprises punch rod 1, cope match-plate pattern 2, lower bolster 3 and guide post 4; Described punch rod 1 is fixedly connected on the top of cope match-plate pattern 2; Described cope match-plate pattern 2 is connected by guide post 4 with lower bolster 3; Described guide post 4 is outer is also arranged with spring 5; Described guide post has 4, is separately positioned on corner, and guiding accurately, and can utilize the screen resilience of spring 5 to make upper bolster up, saves power; The downside of described cope match-plate pattern 2 is from left to right connected with trimming punch 6, holding pad 7 and bending punch 8 in turn; The top of described holding pad 7 is connected with cope match-plate pattern 2 by push rod 9; Described push rod 9 is arranged with returning spring 10; Described lower bolster 3 is fixedly connected with die 11; Described cope match-plate pattern 2 lower surface is also provided with upper limit post 13, is provided with lower limit post 14 in the relevant position of the upper surface of lower bolster 3, for limiting the descending extreme position of cope match-plate pattern 2; Described die shoe 3 is also provided with locating piece 15, is positioned at the right of die 11, and be positioned at the lower right of bending punch 8; Described lower bolster 3 offers row's slug hole 16; Described row's slug hole 16 is positioned on the left of die 11, and the left side edge of die 11 is in row's slug hole 16 scope, and the waste material being conducive to cutting off is discharged rapidly from row's slug hole 16.
Further instruction, the lower surface of described bending punch is lower than the lower surface of trimming punch.
Further instruction, described trimming punch is bent limit trimming punch, and the bent limit of the part that its Qu Bianyu processes is identical.
Further instruction, rectangular U-shaped of described locating piece 15, its Internal periphery is identical with straight flange one end of processing work, and the distance between locating piece 15 and die 11 equals the length of workpiece straight flange one end.Therefore, the design of locating piece 15, namely ensure that the Working position of workpiece is accurate, in turn ensure that the accurate of bending position.
The blanking curved mould that the working (machining) efficiency of the present invention program is high, its course of work is: mix suitable forcing press first to the high blanking curved mould of working (machining) efficiency, and install on the table; Band processing work is placed on die.Operationally, cope match-plate pattern is descending with forcing press for mould, one end of workpiece first under the relativity of bending punch holding pad and concave-convex mold, by one end of workpiece slowly press shaping die; When after trimming punch and absorption surface, waste material excises by workpiece under the relativity of trimming punch, holding pad and concave-convex mold, the limit travel of the cope match-plate pattern of this mould is also the extreme position of the push rod above holding pad, but the design of limited post effectively prevents the damage of push rod and returning spring; The design of row's slug hole, the waste material being conducive to cutting off is discharged rapidly from row's slug hole, and on certain workbench, slug hole also must be offered in corresponding position, just facilitates waste material directly to drop and is with under workbench, can collect waste material with frame.Forcing press backhaul is up, and cope match-plate pattern is up together with holding pad with punch, and finished work-piece by releasing, takes off by the workpiece of blanking curved shaping under the effect of recoil of spring power, namely completes the processing of a workpiece.
The blanking curved mould that working (machining) efficiency of the present invention is high, structure is simple, easy to operate, safe and reliable, and because stamping-out, distortion two procedures once complete, formation efficiency is high.
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.
