Different Types of Blanking Operations
En fabrication de précision, knowing about blanking types is key. Each type has its own benefits and uses in various industries. We’ll look at conventional, fine, and progressive blanking.
Conventional Blanking
Conventional blanking uses a punch and die to cut metal into shapes. It’s great for making lots of simple parts fast and cheap. It works with many materials, from 0.5 to 13 mm thick.
But, it can leave rough edges and bends on thicker materials. So, it’s fast but might not always meet exact quality needs. For more on sheet metal making, check our guide.
Fine Blanking
Fine blanking makes parts with tight tolerances and smooth edges. It uses a special press with a punch, counter punch, and guide plate. This keeps the material flat and cuts out the need for extra finishing steps.
It can handle up to 19 mm thick materials and gets tolerances as tight as ±0.0003 to ±0.002 inches. It’s perfect for industries like auto, aerospace, and electronics where quality is key.
Progressive Blanking
Progressive blanking feeds metal through a die with many stations. Each station does a different task, like cutting or bending. This makes parts as they move through the die.
It’s good for making lots of parts quickly and with the same quality. It’s used in auto, electronics, and more. But, setting it up can be complex, and the edges might not be as smooth as fine blanking.
| Blanking Type | Caractéristiques principales | Material Thickness | Applications |
|---|---|---|---|
| Conventional Blanking | Efficient for simple parts, faster production | 0.5 to 13 mm (0.020 to 0.51 inches) | Fabrication générale |
| Fine Blanking | Tight tolerances, smooth edges | Up to 19 mm (0.75 inches) | Automotive, aerospace, electronics |
| Progressive Blanking | Multiple operations, high efficiency | 0.002 to 0.080 inches (0.05 to 2.03 mm) | Automotive, consumer goods |
Knowing about these blanking types helps understand emboutissage de métaux better. Each has its own strengths, so picking the right one is crucial for any project.
Materials Used in Sheet Metal Blanking
The materials used for blanking greatly affect the parts made in manufacturing. Each material has special properties for different uses. We look at the main materials for sheet metal blanking, their benefits, and where they are used.
Acier
Steel is a top pick for blanking because it’s strong and lasts long. It’s great for parts that need to be tough. There are many types of steel, like carbon and stainless, for different needs.
Carbon steel is cheaper, while stainless steel is better for places that rust a lot.
Aluminium
Aluminum is key in aerospace and cars because it’s light and doesn’t rust. It’s easy to shape, making it perfect for detailed parts. This makes aluminum parts last longer and easier to make.
Copper and Brass
Copper and brass are great for electronics because they conduct electricity well. They’re used in things like connectors and terminals. Brass is also good for looks, used in decorative parts of products.
This summary shows why picking the right material for blanking is important. For more on sheet metal blanking materials, see this resource on materials for blanking.
