This is a common production model in modern manufacturing. Through reasonable planning and optimized use of complementary equipment, a more efficient and stable production process can be achieved.

Cold Extrusion Process Employed in Cold Forging Machines

Cold forging machines are mechanical devices used for metal processing that utilize the cold extrusion process to alter the shape and size of metal materials. The basic principle of cold extrusion is to apply axial force to metal materials at room temperature, modifying their cross-sectional shape and size through extrusion. Below are the general steps involved in the cold extrusion process during cold forging machine operations:

• Preparation: The cold forging machine must first load the metal material to be processed into the feeding mechanism, typically supplied in the form of wire or steel bar.

• Feeding: The feeding mechanism delivers the metal material to the feeding position of the cold forging machine according to predetermined length and speed. The feeding mechanism generally includes feeding rollers and a clamping device to ensure stable material feed.

• Extrusion: The extrusion section of the cold forging machine contains one or more extrusion mechanisms equipped with cold extrusion dies. The metal material undergoes axial force through the extrusion mechanism, altering its cross-sectional shape.

• Cooling: During the cold extrusion process, the material's temperature rises due to frictional heat and plastic deformation. Therefore, after extrusion, the material needs to be cooled to prevent deformation or cracking.

• Shearing: In the shearing section of the cold forging machine, the material undergoes cutting through the shearing mechanism to attain the desired length.

• Discharging the Finished Product: The processed finished products are discharged through the discharging mechanism from the outlet end of the cold forging machine.

In the entire cold extrusion process, the mechanical force of the cold forging machine and the design of the die play crucial roles. Mechanical force is provided through the mechanical drive system, while the die is designed and manufactured in the desired shape and size. Advantages of the cold extrusion process include high precision, high efficiency, retention of the original material's fiber flow, and optimization of the material's physical properties. It is widely used in the production of various bolts, nuts, pins, screws, and rivets.
