A Heading machine is a piece of machinery that can shape metal into components that are net-shaped or nearly so without the use of heat. It uses a series of punches and dies to make these types of parts, and it is used to create headed fasteners such as screws, bolts, rivets, and more. These fasteners are commonly used in automotive manufacturing and electronics as well as bridge construction, and they can be made out of a wide variety of materials. This type of forming process is also called cold working, and it is often used to save money when compared to other machining processes.
A heading machine can be used to produce various parts out of iron, aluminum, and other metals. It can also be used to produce fasteners that are too complex or long to be manufactured using a regular machining process. The heading machine can be used to make these parts in a much more efficient manner, and it can save on production time and costs as well. It can also be used to make parts that are too complex or expensive for a typical machine, such as fasteners that are designed for specialized uses in bridges and aircraft.
The heading machine is an automatic system that can produce a large number of fasteners at high speeds. It starts with a coil of wire, which is then fed into the machine and passed through several dies to form it into the desired part. It can also perform secondary operations such as piercing and trimming to complete the job.
While most people associate the heading machine with making screws, it can be used to make a variety of different kinds of fasteners. It can be used to make everything from small nails to large bolts and rivets. This is because the process is able to produce parts in a much more efficient manner than other methods, such as machining. It can also be used to make parts out of a wide variety of metals, including titanium and super alloys that cannot be produced through normal machining processes.
The machine itself can be modified to fit the specific needs of a customer. This can include the addition of a pre-heating system to handle difficult-to-machine alloys. This is an important modification because it can allow the machine to achieve a higher level of performance and produce more durable parts, which are essential for many applications.
Another type of metal forming process is called upset forging, which can be done at both hot and cold working temperatures. It is similar to head forming, but it involves a larger amount of material and a much more complex geometry. The material can be forged either with open or closed dies, and it can be upset with a single blow or multiple blows.
The most common and basic technique for heading is called an extrusion. This is the most common method for forming the head of a screw or bolt, and it can be done in two ways: forward and backward. Forward extrusions force the material through a die cavity that is smaller than the starting diameter of the wire, which compresses it. Backward extrusions, on the other hand, force the material to flow around a penetrating punch while being contained in a die or punch insert.
