Punch and dies are a type of cutting tool equipment utilized in the high-heat metal forming process known as forging and punching. A die is a supplementary object that the punch press dies to the cutting workpiece during this process. The workpiece portion that the punch press dies down aids in the die-cutting process.
Why is Punch and Die Tooling used?
Greater flexibility in terms of size, proportions, and effectiveness is possible with punches and dies. The dimensions and size of the hole that needs to be drilled may restrict the drilling options available. For larger diameter holes, pre-drilling and additional motor drives are required. On the other hand, punch and die operations allow a wide variety of forms and sizes to be cut out, such as a square or oval shape.
By precisely fracturing the material, the punch operation separates the metal particles. In contrast, a drill’s or hole saw’s cutting action produces a lot of swarf, which covers the work surface in filings and sharp swarf.
A punch and die works by using a solid metal component called the “punch,” which is positioned vertically above the “die.” The die is fixed right below the punch and is the same size and shape as the punch. Typically, a hydraulic drive is used to align the punch with the die.
Punch-and-die Production is Best Suited to Certain Types of Production
When making parts with a punch and die, the workpiece is typically produced or punched, requiring consistency and accuracy across all pieces.
Cutting Process For:
Blanking
By using a strong enough shearing force, a piece of sheet metal is cut from a larger piece of stock during the cutting process known as “blanking.” The “blank,” which is the portion that is removed in this operation, is not scrap but rather the desired component. However, blanking is most frequently used to cut workpieces with simple geometries that will be subsequently modified in the following processes.
Blanking can be used to slice parts into practically any 2D shape. Multiple sheets are frequently blanked in a single operation. Gears, jewels, and components for watches or clocks are some of the final elements that can be made utilizing blanking.
Piercing
Shearing force is one of the several cutting techniques used to cut sheet metal. However, the word “shearing” by itself refers to a particular cutting technique that separates a piece of sheet metal by making straight-line cuts. Shearing is most frequently used to cut a sheet along an existing edge that is held square, although it can also be used to make angled cuts. Because of this, shearing is generally used to reduce sheet stock’s size in order to prepare it for other procedures.
Punching
By using a strong enough shearing force, the material is cut away from a sheet of metal during the cutting process known as punching. Punching and blanking are extremely similar, with the exception that the removed material, known as the slug, is discarded and leaves the desired internal feature, such as a hole or slot, in the sheet. Punching can be used to create cutouts and holes in a variety of sizes and forms. Simple geometric shapes (such as circles, squares, rectangles, etc.) or combinations of these shapes make up the majority of punched holes.
Conclusion
Punch and die are the fundamental tools for sheet metal product processing. To make sure punches and dies function well, manufacturers should first pay attention to their own pro-efficiency well, manufacturers should first pay attention to their own proficiency. Then the punch and die materials that are right in terms of hardness, wear resistance, ductility, and mechanical property factors will influence the perfect process result.
