iter—pf conductor four-roller single pass flat compression diameter forming machine

Abstract

The invention discloses an ITER-PF conductor four-roller single-gate flat compression reducing forming machine which comprises a forming device and a straightening device, wherein the forming device and the straightening device are mutually matched. The forming device comprises a base. An active forming device and a passive forming device are arranged on the base in an erecting mode. A square forming channel allowing a conductor to enter is formed between an inner wheel face of a roller of the active forming device and an inner wheel face of a roller of the passive forming device. The straightening device is located on the back of the forming device and comprises a support. Three sets of horizontal adjusting devices and three sets of vertical adjusting devices are matched with one another and are arranged on the support in an erecting mode. The three sets of horizontal adjusting devices and the three sets of vertical adjusting devices are arranged in a crossed mode, and a square straightening channel allowing the conductor to enter is formed among the inner wheel faces of the horizontal adjusting devices and the inner wheel faces of the vertical adjusting devices. The ITER-PF conductor four-roller single-gate flat compression reducing forming machine can monitor changes of a conductor forming state in real time and control the conductor forming speed. The plane rollers are directly stressed and are big in compressive stress affordability and even in stress. The size of a forming hole can be adjusted, injury of the conductor is avoided, the surfaces of the rollers are easy to clean and finish, and an added water lubrication system greatly improves surface smoothness of the conductor.

Description

technical field [0001] The invention relates to a necessary device in the manufacturing process of an armored superconducting conductor, in particular to an ITER-PF conductor four-roller single-pass flat compression diameter forming machine. Background technique [0002] With the development of science and technology, large-size and high-strength armored superconducting conductors are gradually applied. In the manufacturing process of armored superconducting conductors, the armor of the conductor needs to be reduced in diameter, and the armor is processed by active and passive forming rollers. Squeeze to reduce the gap between the superconducting cable and the armor, so as to achieve a good seal between the armor and the cable. During the compression process of large-sized and high-strength conductors, due to the high compressive stress between the roller and the compressed armor, the roller needs to withstand extremely high forming force, and due to the large compressive st...

AI Technical Summary

Problems solved by technology

During the compression process of large-sized and high-strength conductors, due to the high compressive stress between the roller and the compressed armor, the roller needs to withstand extremely high forming force, and due to the large compressive stress, it is easy to produce material molecular adhesion. The resultant force, the cohesive force that exists between material molecules, can cause bonding on the surface of equipment rollers and damage to the armor surface of conductors
