There are factors to consider when it comes to successful
punching and today we’re going to enumerate some of them. Successful punching
depends on the quality and feature of your punching tools. With these, we can
maximise productivity and the efficiency of the fabrication operation one step
at a time.
Tool Design
There are four essential parts of tool design namely the punch,
die,
stripper and the tool holder system. Successful punching depends on these parts
and relies with the features of the components.
Punch
During the process of punching, the punch
encounters both compressive and tensile forces. As the punch connects with the
surface of the material, it applies pressure until it overcomes the material’s
tensile strength. The material fractures releasing the comprehensive forces on
the punch and producing a hole within the material.
Successful punching depends on the features and design of
the tool that mitigates the forces during the process of punching. Using quality
steel made tools with metallurgic process can endure the extreme process.
Stripper
Performs two important functions; it holds the
work material against the die as the punch penetrates and retracts and the
second function is to hold the punch tip as it punches the hole in the
material.
Die
It requires efficient fit between the punch
and die. A good alignment of the punch
and die ensures the safety and efficiency of the process. Another thing to
remember is the clearance; difference between dimensions of the punch and die.
Die clearance around the punch’s peripherals is important along corners. As
clearance increases with the material’s thickness, so does the radius. With
proper radius the quality of improves the strength and the quality of work when
it comes to punching.
Proper Maintenance
Proper tool maintenance also contributes to successful punching.
With proper lubrication, sharpening using grinding equipment and regular
maintenance of the punch
press to ensure the turret alignment will really make things different when it
comes to punching.
Tooling manufacturers designs tooling for maximum longevity.
Maximising the interval between the regrinds with the use of high-quality
tools, near polished punch flanks and back taper helps the machines up-time and
improving the part quality.
