(1) Consider the strength of the punch; when there is a risk of longitudinal bending and deformation, take measures such as making the punch have a step, changing the punch material, and consider the interchangeability of the punch to try to make it comply with standards.
(2) When punching holes on an inclined surface, when the inclination is less than 15°, make the end of the punch flat; when it is more than 15°, make the end of the punch have a shearing angle, and make it have rigidity and effectively conduct cold stamping.
(3) Use cylindrical recess dies as much as possible within the scope of possibility.
(4) When high-speed punching, due to the heat effect, there is a possibility of gap variation, so make it have rigidity and effectively conduct cooling.
(5) Have a spacer when mass-producing.
(6) When punching multiple holes simultaneously, have a step difference in the punch.
(7) When punching holes in thick plates, have a shearing angle on the punch.
(8) To prevent the occurrence of current cutting chips, take corresponding measures in advance.
(9) Since the sharpening of the punch head for the punching die causes wear on the cutting edge, remove the sharpening blade or base and consider the ease of observation during operation.
(10) When sharpening the punching die, when there are deep multi-punch projections, sharpen the cutting edge of each multi-punch projection individually before sharpening the entire cutting edge.
(11) When the hole position is too close to the R part, the trimming line or other similar holes of the workpiece.
(12) When there is a risk of chip blocking in the mold structure, it is necessary to force discharge.
(13) The standard entry depth of the punch into the recess die is 1-3mm.
(14) When there are strict restrictions on the wall of the hole and requirements for dimensional accuracy, consider special punching such as polished punching and ultra-precision punching, as well as precision machining.
