Energy storage plug cold heading

What is cold heading?

Cold heading is strictly high volume, generating parts by the hundreds of thousands. Figure 6.10. Sequential forming of bolt head by cold heading. Because it is done cold, strain hardening plays a major role in this method, with peculiar consequences for form freedom.

What is the difference between cold heading and hot heading?

While Cold Heading (Forging) is done at room temperature, there also exist the methods of Warm or Hot Heading where heat is applied to the material before the actual processing. As all these methods hold advantages and disadvantages over each other, the right choice of method should be made depending on the desired application of the product.

How can cold-heading reduce costs compared to press-working and cutting?

Pin and terminal processing by cold-heading, which is processed from metal wire, can reduce costs compared to press-working and cutting. we presented a comparison table of each processing method. It is important to select the processing method for each application.

What is a good cold heading condition for a steel die?

Corners are critical. It is difficult to force or flow metal into sharp corners of the die so generous fillets and 1/32 in. minimum corner radii repre-sent best cold heading conditions for most low-carbon and alloy steels. Nickel alloys are likely to gall, and both nickel and stainless steel parts

What are the different types of cold heading operations?

More complex shapes also can be made, including some that are not in the fastener or shaft categories, such as spark plug shells. Additional operations enhance cold heading versatility: trimming, piercing, extrusion, and warm heading. For parts having other than round heads, an additional heading operation called trimming (Figure 4) is performed.

Which chromium stainless steels are processed on a cold heading machine?

The straight-chromium stainless steels, such as Types 410 and 430 are quite often processed on such machines. (Figure 12). Double-Blow Headers—The most commonly used cold heading machine for the chromium-nickel stainless steels such as Types UNS-S30430, 304, 384, and 305 is the double-stroke header. Figure 12.
