A forging machine is used to apply pressure to a metal blank to cause plastic deformation to obtain a forging having a certain mechanical property, a certain shape and size. One of the two major components of forging. By forging, it can eliminate the looseness of the as-cast state of the metal, weld the hole, and the mechanical properties of the forging are generally superior to those of the same material. For important parts with high load and severe working conditions in machinery, forgings are often used except for rolled sheets, profiles or welded parts that are simple in shape. Forging can be divided into: 1 open forging (free forging) according to the forming method. The impact force or pressure is used to deform the metal between the upper and lower two irons (anvil) to obtain the required forgings, mainly hand forging and mechanical forging. 2 closed mode forging. The metal blank is subjected to compression deformation in a forging die having a certain shape to obtain a forged piece, which can be classified into die forging, cold heading, rotary forging, extrusion, and the like. Forging at deformation temperature can be further divided into hot forging (processing temperature is higher than recrystallization temperature of billet metal), warm forging (below recrystallization temperature) and cold forging (normal temperature). The forging materials are mainly carbon steel and alloy steel of various compositions, followed by aluminum, magnesium, titanium, copper and the like and alloys thereof. The raw state of the material is bar, ingot, metal powder and liquid metal. The ratio of the cross-sectional area of ​​the metal before deformation to the area of ​​the die after deformation is called the forging ratio. Proper selection of forging ratios has a lot to do with improving product quality and reducing costs.

Lock washers with external teeth, also known as external tooth lock washers or external serrated lock washers, are a type of fastener used to prevent loosening or rotation of bolts, screws, or other threaded fasteners.
These washers have serrations or teeth on the outer edge, which bite into the mating surface or the underside of the fastener head when tightened. This creates friction and helps to prevent the fastener from loosening due to vibrations or other forces.
The external teeth on these washers are designed to dig into the material, providing a more secure grip compared to regular flat washers. They are commonly used in applications where there is a risk of fastener loosening, such as automotive, machinery, or construction industries.
Lock washers with external teeth are typically made from materials like steel, stainless steel, or other metal alloys. They are available in various sizes and can be used with different types of fasteners, depending on the specific requirements of the application.
