Abstract
The invention discloses a simple blanking and bending die which comprises a stamping rod, an upper die plate, a lower die plate and guide rods. The stamping rod is fixedly connected to the upper portion of the upper die plate. The upper die plate and the lower die plate are connected through the guide rods. The guide rods are sleeved with springs. An edge cutting male die, a pressing board and a bending male die are sequentially connected to the lower side of the upper die plate from left to right. The upper portion of the pressing board is connected with the upper die plate through a push rod. The push rod is sleeved with a return spring. A female die is fixedly connected to the lower die plate. The simple blanking and bending die is simple in structure, convenient to operate, safe and reliable; and due to the fact that the blanking procedure and the bending procedure are finished at a time, generation efficiency is high, and machining accuracy is high.
Description
Technical field
The present invention relates to mould applications, refer in particular to a kind of simple and easy blanking curved mould that simultaneously can complete 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, be necessary to design the one-time formed simple and easy blanking curved mould of a kind of energy.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose a kind of simple and easy blanking curved mould.
Technical solution of the present invention is achieved in that a kind of simple and easy blanking curved mould, 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.
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.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Simple and easy 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, 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 simple and easy blanking curved mode structure schematic diagram of 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.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
Simple and easy blanking curved mode structure of the present invention as shown in Figure 2, 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.
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 simple and easy blanking curved mould 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 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.
Simple and easy 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, 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.
