Heading machine is a metal forming process which uses a series of dies and punches to hammer metal into its desired shape. The process has numerous benefits over screw machining methods such as less waste, more strength, and faster production. The process is also less expensive and environmentally friendly, as it does not use any heat. Additionally, the ability to form material instead of cutting it enables greater control over the final product and creates stronger pieces that require no secondary operations.
The process of cold heading is most often used for producing fasteners such as screws and bolts from a coil of round metal wire. It is an effective method for creating custom components from the raw materials, since it eliminates the need for any additional machining and allows the manufacturers to produce fasteners in a variety of shapes. Cold forming can also be used to create complex parts, since the process does not introduce any thermal stresses into the metal and is able to bend and compress material with great force.
There are a few different types of cold forming, the most common being upsetting and extrusion. Upsetting is a forming technique that involves using a die to force a slug of metal into a die cavity, which is smaller than the initial slug. This can be done with open, between, or enclosed tooling, depending on the shape and location of the upset. It is also possible to form a part with a reverse extrusion, where the slug of metal is forced backward into the die.
Another type of forming is called cold forging, which combines both the upsetting and extrusion techniques to achieve a finished part that is near net shape. This means that the finished component requires very little additional work to finish, such as plating or heat treating. Cold forging is also a very efficient process, since it can be used on large coils of raw metal and can be run at high speeds.
Arai Parts own multiple 9-station parts formers, which has the largest number of stations in Japan, making it possible to perform all the processes of coiled metal forming at once. These machines can forge parts of various shapes out of metals such as steel and aluminum, and they can produce high volumes of these parts quickly and at an affordable price.
The parts formers are made with advanced technology, including a high-quality QT500-7 casting material to assure their robustness and quality. The machine has a hydraulic system that provides adequate and consistent pressure, and it uses a forced lubrication, oil pipe way, and an oil groove to ensure the equipment’s smooth operation and long service life. In addition, it has a pedrail-type slider and a high strengthened material lathe bed that further improves the equipment’s stability and working performance. The machine also has a perfect inspection system, including short material inspection and elimination, overload protection, and lightload stop. This makes the parts formers more accurate and reliable.
