Description

Technical Field

[0001] The utility model relates to the field of forging manufacturing, in particular to a forging device used for producing metal fasteners. Background Art

[0002] Metal fasteners are important industrial parts used to connect and fix two or more components. They are usually made of metal materials and have excellent strength and durability. Common metal fasteners include bolts, nuts, screws, studs, etc., which are used to achieve mechanical connections in engineering and construction fields. The selection of metal fasteners needs to be considered based on factors such as application environment, load requirements, and corrosion resistance to ensure the safety and reliability of the connection.

[0003] Forging is a metal processing process that heats the metal and places it in a mold under pressure and impact to undergo plastic deformation, thereby obtaining parts or products of the desired shape and size. This process can increase the density and strength of the metal and improve its mechanical properties, making forged parts generally more durable and reliable than casting or machining. Forging is widely used in the manufacture of automotive parts, aerospace parts, engineering machinery and other heavy machinery parts, as well as forging high-strength, high-precision tools and equipment.

[0004] The forging device applies pressure to the fixing blank to cause it to undergo plastic deformation to obtain a forging with certain mechanical properties, shape and size. However, when the blank is forged, the oxide scale on the blank usually falls off, and the traditional forging device cannot clean the fallen oxide scale debris in time. The oxide scale debris is pressed into the forging, which will cause depressions on the forging surface and uneven forging structure, affecting the processing accuracy of the forging. Therefore, a forging device for metal fastener production is proposed to solve the above problem. Utility Model Content
