Identifying Common Problems with Punch and Dies for Better Productivity
October 11, 2022When it comes to punches and dies, many elements contribute to the difficulties that arise. If you have issues with punches chipping, breaking, or cracking, we will provide you with some advice or remedies that may be applicable to your specific issues. You can also get in touch with our seasoned professionals, and we would be pleased to assist you.
The following are some contributing elements that lead to your punch and die having the poorest performance. You need to identify these issues to get the most out of your punch and die set and achieve optimal performance.
Ringing
Occurs often with each stroke of the press, deforming the material further with each pass. When the material being cut is of a thickness greater than the punch’s working length or when the punch is entering the die to an excessive extent, the punch will “ring.” Again, adjusting the stroke to enter the die at a maximum of 1/16 of an inch is the most effective way to resolve issues of this nature.
Failure In Stripping
Failure to strip occurs when the stripper has too much clearance, which allows the material to be punched to move around and disrupts the stripping process. Because of this, the punch may suffer an angular fracture. The solution is to modify the stripper to be closer to the material to prevent any unnecessary movement of the substance.
Misalignment
If the punch is not properly aligned with the hole in the die, the clearance from the die will not be uniform. This can cause problems. Checking if the punch and die are aligned is the solution to this problem.
The Process of Chipping And Galling
Regarding punches and dies, some of the issues we run into include face chipping and excessive galling in a single region. This is because the punch and dies are not aligned properly, causing the punch to drag. One potential option is to modify the alignment of the punch and die so that they have the same amount of clearance all the way around.
Loose Nut on The Coupler
If the coupling nut is not tightened properly, the punch may move during the punching operation, resulting in chipping or breaking.
Comprehensive Failure
When the punch and die are used for things that are too difficult for them to punch through, they finally shatter and are destroyed. This issue arises from the punch attempting to punch through materials that are both incredibly tough and extremely thick. Additionally, misalignment is a component that contributes to the failure of the comprehensive approach. The solution is to locate punch and die of good quality.
Breaking of the Head
The loosening of the coupling nut is the most common cause of head breakage. Fracture of the head might be caused by a punch system worn out or by the coupling nut. The solution is to re-tighten the connection nut after several hits and at regular intervals during the day. In addition, you need to check that the front of the system is smooth and has a level surface.
Maintenance is the greatest course of action when preventing issues like these from occurring in the first place.
