Gear Press

Gear presses are the press machines that are designed specifically to produce gears with advanced capacity. For the gears to be pressed out, those pressed gears have to be heat treated and go through the quenching cycle, because normal thermal process would cause further distortion and in order to achieve great repeatability regarding the dimensional tolerance, those gears have to be constrained when they are in the quenching processing, or say quenching cycle. Of course, the exact steps of each gear production would be different, which is decided based on the manufacturers’ methodology so the exact production process is subject to manufacturers’ processing basis and demands. 
 

Gear Pressing Machines

The pressing of the gears are mostly conducted on hydraulic press machines. This type of metal forming machine can be used for a variety of industrial objects as well as those used on a daily basis. Regarding the industrial applications, many are applied to furniture, sports, consumer electronics, household appliances, and industrial sectors. 

Regarding the scales, the size of the die determines the corresponding sizes of the press machines to be used. As a result, manufacturers do require an item whose size is largely different from ordinary products. Nowadays, hydraulic presses are mostly used in the metalworking sectors for a variety of forming tasks, such as forging, molding, clinching, deep drawing, blanking, punching and other metal forming processes onto a wide variety of metal materials. With press machines, cycle time of the production can be minimized by a large margin, while keeping the tolerance values within an acceptable spectrum.

Compared with metal cutting processing, the procedure of metal forming provides a faster shaping process which makes mass production feasible and practical for industrial users. Besides the press models, other stable force pressing mechanics are also facilities utilizing hydraulic forces, for instance, spring machines.

 A spring coiling machine is the machinery that produces coil spring, also known as a helical spring, is a mechanical device which is typically used to store energy and subsequently release it. It can be used to absorb shock, or to maintain a force between contacting surfaces. They are usually made of an elastic material formed into the shape of a helix that returns to its natural length when unloaded. When it’s under tension or compression, the material (wire) of a coil spring undergoes torsion. The spring characteristics therefore depend on the shear modulus on the production lines.
 

Gear Production

After the primary gear work pieces are pressed and well treated, the gear work pieces are not finished at one time but need further treatment. There are a lot of types of gears, such as spur gears, helical gears, double helical gears, herringbone gears, bevel gears, worm gears, hypoid gears, etc. Those gears are made with different shapes and profile curves that need to be processed by different kinds or integrated machine tool series in order to make the gear items more accurate. 

That said, gear presses are not the one and only gear production facility that make the gears once for all, but rather, those pressed gear work pieces need to be further processed with a series of works to enhance the settled specifications by the help of different cutting based machine tools such as turning lathe machines, milling centers, grinding machines, machining centers, etc. 

For the cutting processing of the gears, for instance, the milling machines have to set all the cutting routes on the entire gear items before the real time machining begins. The edges, chamfers, angles, and many other gear related variables are thus further processed by the tooling system and eventually the grinding step comes to solve all the surface roughness issues for the gear products in order to make sure that in the future the operation of the gears can be assured within the planned scales. 

However, if the gear press can make the primary gear work piece within a certain level of accuracy, the whole processing following the forming step could be done with much more easier pace rather than a complicated series of adjustments and modifications. For the metal forming and cutting to be integrated well, the entire production line needs to be done in an integrated way that helps every next step to be set on the expected traces, so the role of the gear press is very important to the entire process.
