As shown in the figure:

W: Indicates the width of the carrier belt. Generally: 12mm, 16mm, 24mm, 32mm, 44mm, 56mm, etc

T: Indicates that the thickness of the material belt is generally 0.3mm, 0.35mm, 0.4mm

0.5mm, etc

A0: indicates the length of the bottom of the carrier slot. Determined by the size of the part

B0: indicates the width of the bottom of the carrier slot. Determined by the size of the part

D: Indicates the diameter of a positive circular hole. Its value is 1.5mm

D1: diameter of center hole. 1.5mm below 32mm and above 32mm

2.0mm

D2: diameter of elliptical hole. 1.75MM*1.55MM

E: Indicates the distance from the horizontal bisector of the positive circular hole to the upper boundary.

Fixed size: 1.75mm

F: Indicates the distance from the horizontal bisector of the positive circular hole to the B0 bisector. By bandwidth

The decisions are: 5.5mm, 7.5mm, 11.5mm, 14.2mm, 20.2mm and 26.2mm respectively

K0: indicates the depth of the slot. Determined by the thickness of the part

K1: indicates the first level depth of the slot

P0: refers to the distance between the vertical bisectors of two adjacent side holes of the punching die joint.

Fixed value: 4.0mm

P: Distance between two adjacent slots A0 bisector.

P2: indicates the distance from the A0 bisector of the slot to the vertical bisector of the adjacent side holes on both sides.

Fixed value: 2.0mm
