The invention relates to a large-diameter multiphase material cold heading preprocessing device which comprises a material cutter, a positioning base, a medium-frequency induction heating device, a digital counting guide wheel set, a numerical control linear transferring device and a steel wire rod straightening device. A steel wire rod is straightened through the steel wire rod straightening device and then becomes a bar material, then the bar material is linearly transferred through the numerical control linear transferring device, moving distance counting control of the bar material is carried out through the digital counting guide wheel set, the bar material penetrates through an induction coil in the medium-frequency induction heating device for induction heating, then the heated bar material undergoes a cold heading cutting process through the positioning base and is cut off through the material cutter, the surface of the bar material is quickly heated to reach a recrystallization temperature through the medium-frequency induction heating device, and accordingly strainless new crystalline grains are generated. Material surface weakening processing can be reasonably carried out before cold heading in an online state so that forming quality of a manufactured product can be guaranteed through best deformation control in the whole operation process and accurate size control.
Description
technical field [0001] The invention relates to the technical field of pre-processing for cold heading, in particular to a pre-processing device for cold heading of large-diameter composite-phase materials, which is used for overcoming the cold-heading operation of large-size and high-strength composite-phase materials. Background technique [0002] For large-scale multi-phase alloy cold heading parts, it is a special part in wind power, shipbuilding, and military industries. With the rapid development of aviation, aerospace, automobile, energy and other fields, various requirements have been put forward for product parts and materials in the industrial process. Various new or special requirements. Subsequently, many high-strength multi-phase alloys such as high-strength and ultra-high-strength steel, high-manganese steel, hardened steel, high-temperature alloys, titanium alloys, chilled cast iron, alloy wear-resistant cast iron, and hardened steel have appeared in modern en...
