Abstract

The invention discloses a blanking-bending mould precise in positioning. The blanking-bending mould comprises a stamping rod, an upper mould board, a lower mould board and a guide rod, wherein the stamping rod is fixedly connected to a position above the upper mould board; the upper mould board and the lower mould board are connected by virtue of a guide rod; a spring is further arranged outside the guide rod in a sleeving mode; from left to right, the lower side of the upper mould board is sequentially connected with a trimming convex mould, a material pressing board and a bending convex mould; the position above the material pressing board is connected with the upper mould board by virtue of a pushing rod; a return spring is arranged on the pushing rod in a sleeving mode; a concave mould is fixedly connected on the lower mould board; a positioning block is further arranged on the lower mould base; and the positioning block is positioned at the right side of the concave mould and positioned at the right lower side of the bending convex mould. The mould disclosed by the invention is simple in structure, convenient to operate, safe and reliable; and the blanking process and the bending process are completed once, so that generating efficiency is high, and processing precision is high.

Description

A kind of blanking curved mould of registration
Technical field
The present invention relates to mould applications, refer in particular to a kind of blanking curved mould that simultaneously can complete the registration of part stamping-out and bending twice technique.
Background technology
Bending process is the needs according to part shape, by mould and forcing press, blank is curved the Sheet Metal Forming Technology method of certain angle, definite shape workpiece.Part shown in accompanying drawing 1 is typical L shape part, workpiece shapes, relatively simple for structure, normally produces in enormous quantities, this part is generally by Blanking Shaping and the machine-shaping of bending twice manufacturing procedure, but two procedures just needs to use two molds, process loaded down with trivial details, and production efficiency is low.Therefore, the blanking curved mould designing the one-time formed registration of a kind of energy is necessary.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: the blanking curved mould proposing a kind of registration.
Technical solution of the present invention is achieved in that a kind of blanking curved mould of registration, comprises punch rod, cope match-plate pattern, lower bolster and guide post; Described punch rod is fixedly connected on the top of cope match-plate pattern; Described cope match-plate pattern is connected by guide post with lower bolster; Described guide post is also arranged with spring outward; The downside of described cope match-plate pattern is from left to right connected with trimming punch, holding pad and bending punch in turn; The top of described holding pad is connected with cope match-plate pattern by push rod; Described push rod is arranged with returning spring; Described lower bolster is fixedly connected with die; Described die shoe is also provided with locating piece, is positioned at the right of die, and be positioned at the lower right of bending punch.
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.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The blanking curved mould of registration of the present invention, structure is simple, easy to operate, safe and reliable, and because stamping-out, distortion two procedures once complete, 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 of registration of the present invention;
Accompanying drawing 3 is the top view of counterdie 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, locating piece.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
The blanking curved mode structure of registration 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 die shoe 3 is also provided with locating piece 13, is positioned at the right of die 11, and be positioned at the lower right of bending punch 8.
Further instruction, rectangular U-shaped of described locating piece 13, its Internal periphery is identical with straight flange one end of processing work, and the distance between locating piece 13 and die 11 equals the length of workpiece straight flange one end.Therefore, the design of locating piece 13, namely ensure that the Working position of workpiece is accurate, in turn ensure that the accurate of bending position.
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.
The blanking curved mould of the registration of the present invention program, its course of work is: mix suitable forcing press first to blanking curved mould, and installs on the table; Workpiece to be processed 12 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, and the limit travel of the cope match-plate pattern of this mould is the extreme position of the push rod above holding pad.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 of registration of the present invention, 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.
