Cold Roll Hole Piercing
Cold roll hole piercing is a process that is used to form holes in sheet metal or plate. It is a cost-effective manufacturing process and is often used for mass-producing parts that require precise holes. Cold roll hole piercing uses a special tool, usually a carbide-tipped tool, to punch a hole in the metal. The process is very similar to punching and is used to create precise, repeatable holes.
The process involves the use of a die set, a punch and the sheet metal. The punch is forced through the metal and the die set forms a cavity that is the same shape as the punch. This forms the hole in the sheet. The sheet material is of a variety of materials and thicknesses, including aluminum, mild steel, stainless steel, copper, brass and metal alloys.
The process allows for the production of high concentrations of holes in metal sheets and plates, without creating burrs or metal chips along the edges of the hole that must be removed. In addition, the process can be used to form hole patterns, allowing for a greater number of holes to be formed in a single operation.
The process typically requires the use of a press, with the press having a relatively high-force capacity. Most presses range in capacity, with some being able to exert force up to 500 tons. The amount of force required will depend on the material being punched and the thickness of the metal.
When the process is complete, the edges of the hole will be as smooth as if they were machined from a tool room lathe. This is due to the rollers being able to minimize material displacement and minimize stress build-up during the process.
Although cold roll hole piercing has traditionally been used to form holes in steel and other metals, it is now being used to form holes in a variety of materials, including plastics, composites and even ceramic materials. This allows for the creation of very precise holes with tight tolerances, without risking damage to the material being punched.
Cold roll hole piercing is considered to be the most cost-effective process for forming holes in metal sheets and plates. The process is easy to set up and does not require complex tool design or other expensive components. In addition, it is a fast process and can be completed with very short cycle times.
Cold roll hole piercing is an excellent choice for companies that need to create precise, repeatable holes in metal sheets and plates. The process is cost-effective and can produce a wide variety of shapes and sizes of holes with high levels of accuracy. Additionally, the process can be used to form holes in a variety of materials, including plastics and ceramics, allowing for a greater degree of flexibility in the types of parts that can be produced.
