It is fixed together and forms discharging part, predominantly give as security material and acted on discharging；Using closely two holes exist in above-mentioned achievable product
The mould structure for carrying out while being punched in the same process punching die.
It is small for the pushing area of spacer bar between two holes that backboard is taken off but using above-mentioned Dies ' Blanking, in blanking process,
Insufficient clamping force is easy to generate recess between two holes of product.
Utility model content
One of the purpose of this utility model is to overcome defect existing in the prior art, provides a kind of quality loop closely
Punching die is punched component by setting twice, improves and lead to the problem of recess between two holes of product.
In order to realize the above technical effect, the technical solution of the utility model are as follows: a kind of quality loop short distance punching die,
It is characterized in that, including the first station punching die and second station punching die, the first station punching die and second station punching
Punch die includes upper die and lower die and at least two adjacent formed punches, the first station punching die and second station punching die
Punch shape it is consistent, the formed punch of the first station punching die is dimensioned slightly smaller than the formed punch of second station punching die.
Preferred technical solution is, it is corresponding that the first station punching die with formed punch in second station punching die cuts face
Dimensional parameters ratio is (0.7~0.95): 1.
Preferred technical solution is, it is corresponding that the first station punching die with formed punch in second station punching die cuts face
Dimensional parameters ratio is (0.8~0.9): 1.
Preferred technical solution is that formed punch is round punch, and dimensional parameters are the diameter that formed punch cuts face.
Short distance hole-punching method in quality loop the following steps are included:
S1: will be placed in the first station punching die to punching processing product, and the formed punch of the first station punching die pushes
To form short distance blind hole on punching processing product, semi-finished product is obtained；
S2: semi-finished product obtained by S1 is placed in second station punching die, under the formed punch of second station punching die
The outer rim for being pressed in blind hole forms short distance through-hole, obtains finished work-piece.
Preferred technical solution is that the hole depth of blind hole is less than the thickness to punching processing product.
Preferred technical solution is that the hole depth of blind hole is (0.6~0.83) with the ratio between the thickness to punching processing product: 1.
Preferred technical solution is that the hole depth of blind hole is (0.7~0.8) with the ratio between the thickness to punching processing product: 1.
Preferred technical solution is, is (2~5) to the ratio between the thickness of punching processing product and adjacent through-holes interval width:
1。
Advantages and beneficial effects of the utility model lie in that
The utility model short distance punching die includes the first station punching die and second station punching die, band punching
Workpiece forms smaller blind hole by the punching of the first station punching die, then is punched to be formed by second station punching die
Through-hole；
Due to first time punching formed punch between interval it is larger, upper and lower mould and to the contact area between punch workpiece compared with
Greatly, upper and lower mould and piece-holder are stablized；Blind hole forms reinforcement structure to workpiece；The punching side of second of punching is relatively thin, workpiece institute
It is smaller by shearing force；Above-mentioned three kinds of factors each contribute to the technical issues of solving short distance punching interval deformed depression on workpiece.
Detailed description of the invention
Fig. 1 is the schematic perspective view of 1 cover plate ontology of the utility model quality loop short distance punching die embodiment；
Fig. 2 is the structural schematic diagram of finished work-piece.
In figure: 1, the first station punching die；2, second station punching die；A, upper mold；B, lower die；C, formed punch；D, half
Finished work-piece；E, through-hole；F, finished work-piece.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and cannot be used as a limitation the protection model of limitation the utility model
It encloses.
[formed punch]
Formed punch includes but is not limited to round punch, further includes triangle, ellipse and abnormal-shaped punch, and abnormal-shaped punch is existing
There is known punch structure.The formed punch of first station punching die is dimensioned slightly smaller than the formed punch of second station punching die: formed punch
