A successful deep drawing process depends on a lot of factors. Not paying attention to even one of those factors can result in lot of problems. Take a look at these tips to help you gain a better understanding of how things work:
Get the metal flow right
It’s important that the metal flow is properly initiated. When you’re designing or building or even troubleshooting deep drawing stamping dies, make sure you work with the right type of material. Factor in the thickness along with the N and R values. Also include the part geometry, press speed and blank size as well as shape of the material. Then go with the draw ratio, draw radii and die temperature to match. The proper lubricant as well as binder pressure and binder deflection must also be considered, along with the standoff height. All these should ensure that the deep drawing process generate positive results.
Be on the lookout for defects
Defects during the process can easily prevented when you monitor the process factors carefully. Tearing is a usual result of most defects. This is caused by the excessive thinning in areas of the sheet metal where the defect is often found. Other reasons for the tearing might be a blank shape that proves inefficient. Bad geometry can also be at work, says The Library of Manufacturing. So make sure you keep an eye out for tearing and figure out what the problem is right away.
Use drawbeads
You can use this to regulate and control the metal movement when you’re deep drawing. By traveling right into the die cavity, these drawbeads can bend as well as unbend metal with ease and alter the flow, as a result.
