The waist of isosceles trapezoid and two bases form the first acute angle and the first obtuse angle respectively；First acute angle is 1 ° -60 °；First isosceles ladder
A height of 0.1-25mm of shape；The vertical section in the second round platform portion is the second isosceles trapezoid, the waist of the second isosceles trapezoid and two bases
The second acute angle and the second obtuse angle are formed respectively；Second acute angle is 70 ° -89.9 °；Height and the first isosceles trapezoid of second isosceles trapezoid
High sum be 1-50mm.
First handle in the first round platform portion is shock surface, and the second largest bottom in the second round platform portion is working face, second largest bottom
Area is the area in the hole gone out.Being shaped as second round platform portion is inverted round table-like, it is therefore an objective to avoids stainless steel plate crimping.Circle
Post portion is clamping part, for being fixed on perforating press.
This programme has the beneficial effect that：Impact portion of the first round platform portion as punching, the area of its first handle is small, is easy to
Holes, the resistance of holes is reduced, reduces the active force between punching needle and stainless steel plate, reduce the consume of punching needle,
So as to extend the service life of punching needle.
Not having to material or the different size of punching for sheet material, the structure of required punching needle is also different, and first
The height of the size of acute angle and the second acute angle, the height of the first isosceles trapezoid and the second isosceles trapezoid can be adjusted suitably, to reach most
Good using effect.
Preferred scheme one：Based on scheme preferred scheme, a height of 3.5mm of the first isosceles trapezoid；Second isosceles ladder
A height of 15.7mm of shape.
Preferred scheme two：Preferably one preferred scheme, a diameter of 12mm at upper bottom；Second handle it is a diameter of
9mm.The diameter at upper bottom is more than the diameter of the second handle, and after ensureing punching, the first round platform portion and the second round platform portion pass through hole, cylinder
Portion is thick compared with the second round platform portion, and cylindrical portion can not pass through hole, be blocked.It can so ensure that the hole gauge lattice gone out are consistent.
Preferred scheme three：Preferably two preferred scheme, the first acute angle are 12.5 °；Second acute angle is 83.5 °.
The size is both easy to punching, can avoid crimping again, and the service life of punching needle is longer, is ideal size.
