Description
Technical field
The utility model relates to punching machine mold, relates in particular to the one-time formed stretching of sheet material hole flanging and pierces through mould.
Background technology
In sheet material processing, often relate to the flange processing in hole, traditional method is with numerical control press elder generation punching flange again, two procedures is porose die-cut intact institute earlier, carries out flange more one by one.Yet, because numerical control press is located and had error, reach sheet deformation, cause the hole of processing earlier qualified, cause the flange hole secundly of back processing easily, be uneven, do not reach predetermined effect.
State Intellectual Property Office is in the CN202028682U of 2011.11.09 bulletin, and name is called the patented technology of " the hole flanging mould of high flange on the thin plate ".The extruding earlier of a kind of patrix is provided, and counterdie is the mould of hole flanging again, in use, the breaking of material when having prevented back hole flanging, simple in structure.But be not difficult to find out that the extruding punching pin in use damages easily in this structure patrix, need often to change; And only be provided with in the counterdie and take off the material spring, the phenomenon of skew takes place easily.
The utility model content
The utility model provides a kind of assurance upper mold core structural strength to above problem, strengthens the stretching of the one-time formed numerical control press of guiding and pierces through mould.
The technical scheme of the utility model is: comprise upper die and lower die; Said patrix comprises mould body, upper mold core, top board, connecting rod and patrix unloading mechanism; The said mould body of going up is provided with stepped hole, and said upper mold core is provided with adaptive step circle and connects the said stepped hole of going up mould body; Said top board and connecting rod are fixedly connected sequentially on said on the mould body, and said connecting rod is fixedly connected through connecting bolt with last mould body; Said counterdie is provided with the hole flanging thimble; Said upper mold core bottom face is the plane; Said counterdie comprises mould body, holding pad and counterdie unloading mechanism down, and said holding pad is located at down mould body top; Said counterdie unloading mechanism comprises material returned spring and guide pin, and said material returned spring and guide pin connect between said holding pad and the following mould body.
Said patrix unloading mechanism is located in the hole of said upward mould body, comprises spring and spring pad post, and said spring is located between said spring pad post and the said upper mold core.
Also comprise holding screw, said mould body bottom surface down is provided with mesopore; Said hole flanging thimble bottom is bar shape, and said holding screw connects said hole flanging thimble from the said mesopore of mould body down.
Said top board is provided with dogbolt, and the said mould body of going up is provided with keyway.
The utility model has been simplified two procedures before at work, has realized one-shot forming, earlier sheet material is stretched, and then it is being pierced through, and can not have the error that exists owing to reorientating.The bottom of upper mold core is set as the plane than the extruding punching pin, has guaranteed the intensity and the service life of core rod.On counterdie, be provided with guide pin, avoided the guiding problem in motion process.The utility model is simple in structure, and working time has been practiced thrift in the time processing moulding, has improved operating efficiency.
