What is what is what is the toothed?
Cogging is a method of processing metal used to change the grain of a piece of metal. It is a technique of fitting hot fittings including two anvils with shaped surfaces. This kind of shaped anvil is called "die". The term "circulation" may come from the fact that the metal is to be pushed into the shape of the matrix in the same way as two wheels fit together, although the shape of the matrix is not always rectangular.
COGGING is often a temporary stage of the process of metal processing. It is used to change the internal structure of ingots. For the first time, ingot is formed after the first melting of the raw metals and then poured into the molds. The metal is easier to handle, but will have to undergo further fittings and temperament before it can be used. After kogging, the finished ingots, now called the Sochors, are refined pieces of metal, which can then be forged or thrown into more complex ingredients.
The process of cogging begins with heating metal ingots until they are marty but not molten. Ingots are located between two shaped dies. AfterThe hill of dies is shaped to stimulate the metal to form a certain shape. The hot ingot then turns and repeatedly interferes between two dies. Depending on the shape of the used anvils, the finished ingot, now called Sochort, can attract many different shapes. It can be rounded, square or even hexagonal.
During the orbiting process, ingot with each blow slightly longer. As the ingot extends, the metal grain changes and is longer and homogenized. The rotation of ingot between the strikes promotes even shaping and extension. This effect associated with the compression of the center of ingot, as is repeatedly affected, further strengthens metal. In the variant in this process, the metal is sometimes shaped by cylinder pressure into the shape of the matrix and then rotates to the final form.
Cogging metal is a long process that requires many modifications. The metal will have to be re -heated between the strikes to remain tradable. Ingot may need a hundredVKY strokes after its length before reaching the desired shape and strength. Some machine fittings have been developed to make this process easier. The number of strokes and the amount of force used can be programmed so that the ingot remains uniform.
