Summary of the invention
The purpose of this utility model is to provide a kind of compound die counnter attack burr structure.
For achieving the above object, the technical solution adopted in the utility model is: a kind of compound die counnter attack burr structure, comprises upper die and lower die;
Described patrix comprises top board, cope match-plate pattern and upper de-plate, and cope match-plate pattern is fixedly connected with top board, and cope match-plate pattern corresponds to upper de-plate and offers assembly cavity, and upper de-plate to be located in assembly cavity and to be connected with described top board by the first spring;
Described counterdie comprises base plate, lower bolster and lower de-plate, and lower de-plate is connected with described base plate by the second spring, and lower de-plate offers lower assembly cavity corresponding to lower bolster, and lower bolster to be located in lower assembly cavity and to be fixedly connected with base plate;
Described lower bolster and upper de-plate positioned opposite;
Described cope match-plate pattern and lower de-plate be provided with anti-fore-set, anti-fore-set by cope match-plate pattern and lower de-plate spaced apart, and make the gap between cope match-plate pattern and lower de-plate be greater than the thickness of sheet material to be processed.
Related content in technique scheme is explained as follows:
1, in such scheme, in an initial condition, upper de-plate stretches out cope match-plate pattern 0.5 millimeter.
2, in such scheme, after punching press, the sheet material stayed between lower bolster and upper de-plate is product, and remainder is waste material.
3, in such scheme, the height of described anti-fore-set is 2.5 ~ 3 times of sheet metal thickness.
Utility model works principle and advantage: during punching press, sheet material to be processed is placed between upper die and lower die, patrix is close to counterdie, first anti-fore-set contacts cope match-plate pattern, patrix continues to decline, the upper de-plate of sheet material upper surface contact, patrix declines further, lower bolster is pressed into cope match-plate pattern, sheet material is cut off, product and waste material is formed with this, product is stayed on lower bolster, waste material is stayed on lower de-plate, then patrix rises, owing to being separated by anti-fore-set between cope match-plate pattern and lower de-plate, upper de-plate takes off when expecting and there is gap between product and waste material, patrix continues to rise, lower de-plate makes waste material depart from lower bolster, product is positioned at above waste material, product no longer contacts with waste material, anti-burr can not be produced.The utility model structure is simple, only need increasing anti-fore-set on existing mould, without the need to changing other structures of existing mold, can obtain beyond thought effect.
