Talking about the assembling punches and assembling dies, they are special assembling components for stamping tools that was assembled by two individual components. Usually, one individual component is made of carbide material, another individual component is made of hardened steel material.
Why need to assemble two individual components together?
As we know, a set of stamping die includes many components and spare parts. Some key components are stamping punches, and stamping die inserts. They are also wearing parts. In order to prolong their lifespan, we need to use hard metal (HM), that also called tungsten carbide.
But carbide also has some shortage, one of the shortage is that it is very expensive, another shortage is its fragility that it is easily fragile.
In order to solve the problem, some stamping tool mechanical designers invent the assembling dies and assembling punches.
Assembling dies with carbide and hardened steel
For assembling die, usually a small carbide component was embedded into a bigger hardened steel component. When they were assembled together, or called installed together, A set of assembling die was finished.
As the core use area is the carbide component, it would have a longer lifespan. The outer area is hardened steel that has a lower material cost that also can save the cost.
Assembling punches with carbide and hardened steel
The same applies to assembling punches. The key use area is carbide material, the heel place or the outer place is the common hardened steel.
The carbide component and hardened steel component will be assembled together.
Assembling Methods for Assembling punches and Assembling dies
There are several methods for the assembling punches and dies.
- Soldering Method: We can solder carbide and hardened steel together by soldering. It seems easy, but how to control solder temperature and strength is a technical activity.
- Expand when heated and contract when cooled: This is a principles of physics. After the bigger hardened steel component and small carbide component both were finished machining. We can heat the bigger hardened steel component, its dimension will expand when heated, then we put the small carbide component into the bigger hardened steel component. And then wait for them to be cooled. The assembled component with carbide and hardened steel will be perfectly integrated together.
- Glue Method: This method looks simple, but also has some technical difficulties. First, we need to use the right glue with strong gluing ability to make sure the two components can stick together tightly. In some cases, we may also need to combine the thermal expansion method.
So that’s all about assembling Punches and Dies with Carbide and hardened steel Integration for stamping tools. Hope our introduction would be helpful. If you have any needs for these kinds of assembled parts, you can also contact us for a try.
