Tips for a Safe, Successful, and Successful Punching Mild Steel
Punches should be worn down and should not crack or chip. Several factors may contribute to punch chipping and cracking. Here's a simple list that will help minimize the chance of failure.
Loose coupling nuts
This allows the punch to "move" throughout the process of punching. This could result in unbalanced pressures.
Missalignment
If the punch is not aligned with the hole in the die, an uneven clearance can result. This could result in uneven pressure to the punch's face.
Incorrect clearance of punch and die
1/32" is the maximum acceptable clearance for form punch punch and die, which is less than 1/2" thick. The material to be punched which is 1/4" or thicker will require an additional clearance of 1/16". Punching mild steel over 3/4" thick could require greater clearance from the die.
Uneven stripping
This occurs when the stripper of the machine fails to firmly and evenly keep the plate in place in the "up" stroke. This happens when the whole plate's weight as well as the strain from stripping are concentrated on one side or edge of the punch. In extreme circumstances, as much as 1/2" of the punch can break off.
You can manage certain of the situations we have mentioned on the floor of your shop. It is our responsibility to provide you with the most effective punches. This is accomplished with the most shock-resistant tool steels. Then, we machine them to precise tolerances and to harden them and temper them using precise metallurgical processes.
Punches break and crack easily when you punch plates with an average thickness of 1/2". These conditions are extremely challenging for punches that were developed by our engineers.
The importance of longevity in Punching Tools And Why It Is Important
Quality control is crucial. Brands that are not reliable will get a bad rap from consumers. aren't reliable and consistent, regardless of their industry. Equipment that is not of the highest quality could result in a loss of credibility, lower revenues, lower productivity, and lower morale among employees. Whether your fabrication business is in its infancy or you're established and looking to increase your earnings making investments in equipment that maximizes longevity will also give you the greatest ROI.
For fabrication shops, form punch are critical to their work. FMA calls them "the Swiss Army knife of the fabrication shop." Although there are numerous process improvements to ensure quality products, the most important step in maintaining a productive and cost-effective workplace is to invest in punching equipment that last. These best practices should be followed by any producer.
As a materials consultant
The most important rule for long-lasting punch tools is to pick the material for your tool that matches the material being punched. A reputable manufacturer of punch tools will act as a materials consultant to help you determine the right material for your punch tool. For example, A2 steel is what punches have been historically constructed from. It's strong, versatile and stable in dimensionality during heat treatment. However, if you're stamping high-strength, low-alloy steel (HSLA) or another high-tech product, then A2 isn't up to the job. You require a punch with superior compression and shock resistance such as CPM-M4 or M2. For high load applications, you will see better results using M2 steel.
A change in your perspective is necessary to increase the life expectancy of your punch tools. It is possible to increase the price of your punch tool by using higher-quality materials and adding coatings. It is important to compare this with the materials that are of low quality. It is crucial to think about the cost of replacing parts and the effect on productivity.
