The rectangular area of a pair of of opposite side.
Preferably, above-mentioned a pair of of bar shaped location hole is all vertical through holes.
Advantages and beneficial effects of the utility model lie in that quadrangle distribution through-hole can be gone out on sheet metal component by providing one kind
Punching die can go out four through-holes on the mainboard body of sheet metal component, which is distributed in quadrangle, and four through-holes
Position it is adjustable；Lower template is equipped with a pair of of bar shaped location hole, can position to sheet metal component, the precision of punching can be improved；Punching
Mainboard body is also waited for that the region of punching is pressed in lower template, the precision of punching also can be improved by Kong Shi, washer.
Each material-dropping hole is located on same circumference, and each material-dropping hole is arranged at equal intervals on the circumference, due to screw hole and blanking
Hole corresponds, therefore each screw hole also is located on same circumference, and each screw hole is arranged at equal intervals on the circumference；Simple inference can
Know, cope plate bottom surface any four screw hole is all in quadrangle distribution (i.e. four screw holes are located on four vertex of a certain quadrangle).
Four formed punches can be spirally connected with four screw holes of cope plate bottom surface, from the foregoing, it will be observed that cope plate bottom surface any four screw hole
All it is distributed in quadrangle, therefore four formed punches are also in quadrangle distribution (i.e. four formed punches are located on four vertex of a certain quadrangle),
Four through-holes being distributed in quadrangle can be gone out (i.e. four through-holes are located on four vertex of a certain quadrangle).
Four formed punches can be spirally connected with any four in the multiple screw holes in cope plate bottom surface, i.e., the position of four formed punches can be flexible
Adjustment can go out four holes of different size (position distribution that the difference of different size essentially consists in four through-holes is different).
The application method of the utility model punching die is as follows:
First four formed punches and previously selected four screw holes in cope plate bottom surface are spirally connected one by one.
Sheet metal component is lain against in lower template, the bottom surface of sheet metal component mainboard body and the top surface of lower template recline, and sheet metal component
A pair of side plates body be inserted into corresponding bar shaped location hole, sheet metal component is positioned by a pair of of bar shaped location hole.
Cope plate decline four formed punches of driving move down, and each formed punch is respectively installed with compressed spring and the washer (internal diameter of washer
Greater than the outer diameter of corresponding formed punch, and the internal diameter of washer is less than the outer diameter of corresponding bulge loop), since the bottom surface of washer is located at corresponding formed punch
The lower section of bottom end end face, therefore washer is first contacted with sheet metal component mainboard body, after washer contacts mainboard body, corresponding compressed spring is pressed
Washer can be pressed on mainboard body by contracting, compressed spring, i.e., mainboard body is waited for that the region of punching is pressed in lower template by washer；Four
The mainboard body of a ram impacts sheet metal component, goes out four through-holes on mainboard body, and the waste material swept away is exported by corresponding material-dropping hole.
After the completion of punching, cope plate, which rises, to be resetted, and is resetted respectively after each washer and the disengaging of sheet metal component mainboard body.

21 be the rectangular area of a pair of of opposite side.
Preferably, above-mentioned a pair of of bar shaped location hole 21 is all vertical through holes.
The utility model punching die can go out four through-holes on the mainboard body 31 of sheet metal component 30, four through-holes
It is distributed in quadrangle, and the position of four through-holes is adjustable；Lower template 20 is equipped with a pair of of bar shaped location hole 21, can be to sheet metal component 30
It is positioned, the precision of punching can be improved；When punching, mainboard body 31 is also pressed on lower template 20 to the region of punching by washer 14
On, the precision of punching also can be improved.
Each material-dropping hole 22 is located on same circumference, and each material-dropping hole 22 is arranged at equal intervals on the circumference, due to screw hole with
Material-dropping hole 22 corresponds, therefore each screw hole also is located on same circumference, and each screw hole is arranged at equal intervals on the circumference；Simply push away
Reason is it is found that 10 bottom surface any four screw hole of cope plate is all in that (i.e. four screw holes are located at four tops of a certain quadrangle for quadrangle distribution
Point on).
Four formed punches 11 can be spirally connected with four screw holes of 10 bottom surface of cope plate, from the foregoing, it will be observed that 10 bottom surface of cope plate any four
A screw hole is all in quadrangle distribution, therefore four formed punches 11 are also in that (i.e. four formed punches 11 are located at the four of a certain quadrangle for quadrangle distribution
On a vertex), four through-holes being distributed in quadrangle can be gone out (i.e. four through-holes are located on four vertex of a certain quadrangle).
Four formed punches 11 can be spirally connected with any four in the multiple screw holes in 10 bottom surface of cope plate, i.e., the position of four formed punches 11
It can be adjusted flexibly, can going out four holes of different size, (difference of different size essentially consists in the position distribution of four through-holes not
Together).
The application method of the utility model punching die is as follows:
First four formed punches 11 and previously selected four screw holes in 10 bottom surface of cope plate are spirally connected one by one.
Sheet metal component 30 is lain against in lower template 20, the bottom surface of 30 mainboard body 31 of sheet metal component and the top surface of lower template 20 are pasted
It leans on, and a pair of side plates body 32 of sheet metal component 30 is inserted into corresponding bar shaped location hole 21, sheet metal component 30 is by a pair of of bar shaped location hole 21
Positioning.
Decline four formed punches 11 of driving of cope plate 10 move down, and each formed punch 11 is respectively installed with compressed spring 13 and washer 14
(internal diameter of washer 14 is greater than the outer diameter of corresponding formed punch 11, and the internal diameter of washer 14 is less than the outer diameter of corresponding bulge loop 12), due to pad
The bottom surface of circle 14 is located at the lower section of corresponding 11 bottom end end face of formed punch, therefore washer 14 is first contacted with 30 mainboard body 31 of sheet metal component, washer
After 14 contact mainboard bodies 31, corresponding compressed spring 13 is compressed, and washer 14 can be pressed on mainboard body 31 by compressed spring 13,
I.e. mainboard body 31 is pressed in lower template 20 by washer 14 to the region of punching；Four formed punches 11 impact the mainboard body of sheet metal component 30
31, four through-holes are gone out on mainboard body 31, the waste material swept away is exported by corresponding material-dropping hole 22.
After the completion of punching, cope plate 10, which rises, to be resetted, and multiple respectively after each washer 14 and the disengaging of 30 mainboard body 31 of sheet metal component
Position.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
