A consequence of this is that it is essential that the cold forming load must be disc below the tensile strength of the material but above brake the yield strength of the key material. These mechanical properties of the work-piece are directly influenced disc by its metallurgical structure of the wire and thus any pre-treatment it has undergone. Cold Forming Techniques Cold forming can be undertaken by a number of different techniques or any combination of them. brake Upsetting, Reverse Extrusion, Forward Extrusion, Piercing and Trimming. Upsetting In upsetting the billet is sheared then placed key between a punch and a die and a vertical load applied. During this stage the material flow is generally at 90degrees to the direction in which the load is applied. Reverse or Backward Extrusion is the most common method of producing tubular / hollow components. During reverse extrusion the work-piece is contained within a die while an extrusion punch/pin is forced into it in a vertical direction. This causes the material to flow parallel to the pin but in the opposite direction to the direction of travel of the pin.

During piercing a punch is forced into the extruded bore with the aim of punching a solid slug of material equal in diameter to the piercing punch form the formed component. The slug of material pierced from the work piece is normally scrap. As the punch is forced into the work-piece the material is first plastically deformed over the piercing sleeve. As there is limited clearance between the punch and die when the material deformation exceeds the plastic limit it disc and brake will suddenly shear / rupture through the remainder of its thickness.If the punch and key die have the correct clearance it will disc and brake be possible to use the pierced bore without a key further finishing operation. Orbitforming is a cold disc forming process in which an orbiting tool held brake at a fixed angle is used to progressively move malleable material into a desired, predetermined shape.

Cold forming, or cold heading, uses forces greater key than a metal''s elastic limit to form shapes without causing scrap material. Since raw material can be the most expensive aspect of a part, cold forming disc is often a lower cost alternative brake to screw machining and other manufacturing key methods. disc Benefits of Cold Forming Quality Improved strength and reliability through work hardening and an uninterrupted grain brake flow Improved key surface finish over screw machined components Design Flexibility Unique and diverse shapes, including parts with multiple diameters, extrusions, blind holes and through holes Large head to shank disc ratios without secondary machining Eccentric brake or asymmetrical bodies possible Reduced Costs Reduced scrap rates High production rates Ability to form parts to a net or near-net shape, which requires fewer secondary operations to achieve finished form Allows multi-piece assemblies to be manufactured as a single component Cold forming often key uses significantly less raw material for the same component.
