The call method for the standard punch
The standard punch mainly includes 5 kinds of blade section shapes, among which the circular blade section shape is relatively simple with only one diameter parameter.While several other blade section shapes involve multiple parameters such as length (P), width (W) and rounded Angle (R).
Each parameter has a certain range of selection, and the blanking gap filler is also taken into account. Therefore, the mold designer needs to spend a lot of time to query data and check the blade section shape parameters when selecting the standard punch.
Because the diameter of the punch and rushed by the thickness of the sheet, punch and die, there will be a gap between the gap value is usually 6% - 8% of the material thickness, the section size of punch edge is often given to two decimal places, thus causing the standard punch specification code is very long, achieve hundred characters, even after completion of the design of complete parts list when workload is huge, decorative pattern conveyor belt and very easy to get wrong.
Standard punch blade section shapes, logic, database class functions, and has strong data filtering, call functions.Making full use of these functions and making a table of parts with the function of judgment and search will make the selection of standard punch forms a very easy job.
