Cold Forging In Spline Gear Production

In the manufacturing of the automobile, many parts are brought together for the machine to work. Note that the whole automobile machine is designed by bringing together multiple parts that connect to each other form a whole unit. If just one part fails to work, then the whole machine will stall. That’s how all machines are quite intricate and requires a professional to fix a fault. One of the crucial parts of the automobile system is the spline gear. The spline plays a critical role in the effective running of the machine.

Spline gears have one major role in automobiles – they connect two shafts to other components that transmit torque and rotation. If you have a car or a motorbike, the spline gears transmit the torque and rotation from the engine to the wheels. That’s how the machine starts moving. If the spline gets faulty, the torque and the rotation won’t be transmitted to the required components. This means the machine wont function properly.

Spline gears come in a variety of shapes, depending on where they are being used. They can be straight, involute, or tapered, among many other forms. So the forming of the parts may be different because of the varying shapes. The forming technologies for the automobile have been increasing over the years. But some are widely popular because of the numerous benefits that they offer to the manufacturer and the users. One of these is cold forging, also known as cold extrusion technology.

Application of Cold Forging In Spline Gear Production

Cold forging, also referred to as cold extrusion, is one of the popular forming technology in the automobile and other machine parts. As the name suggests, this is a forming technology that works on the metal at room temperature. Unlike hot forging, you don’t need to heat the material to be formed to crystallization temperature to form it.

Forging technology makes use of compression force to create a plastic deformation. When the metallic material is in this condition, it is easy to form it to the desired shape. That’s simply how the spline gears are formed using cold forging technology. But the modern cold extrusion technology is using one of the most advanced machines. Today, most manufacturers have adopted the use of hydraulic press machines for cold forging these parts.

The hydraulic press machine for cold forging has three main parts: the press system, press chamber, and the mold. The mold or the die is the one that produces the kind of spline gears needed. The hydraulic system produces the compression force that’s needed to press the material to produce plastic deformation. Several factors, such as the amount of compression force, also matters.

How To Cold Forge Spline Gears

The cold forging of spline gears is a pretty straightforward process. If you have a perfect cold extrusion machine, it will be easy to handle these parts’ production. You need to get right is the compression force produced by the hydraulic system and the mold. These are two very critical aspects that determine the quality of the spline.

Make sure that the die or the mold is properly fitted in the press chamber to avoid movement when pressing. With the machine ready set, get the material you want to make the spline gear from and place it on top of the mold. Then start pressing using the punch. The material will undergo plastic deformation due to compression force. The pressed metal will take shape and the size of the mold. That’s simply how spline gears are formed.

Advantages Of Cold Forging Spline Gear

There are many advantages that come with cold forging spline greats. One of the biggest advantages is the fine surface. Cold forged machine parts require little or no finishing work. The cold extrusion also produces near-net-shape parts, which means saving the materials. Apart from the excellent surface quality, the cold forging of spline gears also produces a high dimensional accuracy level.
