Rolling Steps – Ugigrip-Vallgrip

Like cold-forging, rolling is a metal forming process.

At Ugigrip-Vallgrip, rolling is mainly used to produce threads, knurling, grooves, etc., from a headed blank

It takes place in a second stage, after the cold-forging operation that gives the part its basic shape. This process deforms the part by pressure between two dies to obtain the final shape, according to predefined machine settings.

To provide production finishes, several options are available, such as coating (zinc plating) or heat treatment.

What should you pay attention to?

It is essential to always consider the volume of the blank in order to anticipate the deformation created during the rolling process.

Why ? Because the part will elongate during deformation, so it is necessary to have sufficient material to produce the final component.

Cold Forging Deformation Steps Ugigrip-Vallgrip

Cold-forging is a manufacturing process that uses 100% of the raw material — metal wire — to form the final part.

The part is created through the deformation of this wire: it is struck several times, across multiple stations, without any material loss.

The slug — the cut wire — is formed within successive dies. Depending on the machine, there may be between 3 and 6 or 7 stations, corresponding to the number of times the part is struck.

The final part produced by cold heading is called a “blank.”

Question

Which raw materials can be used?

Steel, copper, aluminum, and brass wire are commonly used.
It is also possible to produce simple stainless steel parts. However, when the part becomes complex, an additional heating station must be added to the machine.

To provide production finishes, several options are available, such as thread rolling.
