Abstract

The invention belongs to the technical field of superconducting material preparation equipment and relates to a double-layer foil winding machine for preparing a superconducting wire. The machine comprises a machine body, a double-discharging mechanism and a receiving mechanism. Double layers of foil material rolls discharged by the double-discharging mechanism is connected with a corresponding brake and a whole machine control system through respective tension detection units; double deviation rectifying systems are arranged in front of the double tension detection units and are connected with the complete machine control system, and each deviation rectifying system is connected with a respective corresponding deviation-rectifying executing mechanism. A clamping mechanism is arranged in front of the double-deviation-rectifying system, an alignment mechanism is installed at a front end of the clamping mechanism, and a shearing mechanism is installed at a front end of the alignment mechanism and located at a rear end of a base metal bar. The double layers of foil material rolls pass through the alignment mechanism and the clamping mechanism to be converged and overlapped to form double layers of foil rolls, the double layers of foil rolls are rolled onto the base metal bar through the shearing mechanism and then are pressed through the pressing mechanism to form a base metal bar-double-layer foil roll. The whole machine control system integrates all control units and logic control, the automation degree is high, and the compactness of a finished product is high.

Description

technical field [0001] The invention belongs to the technical field of superconducting material preparation equipment, and relates to a double-layer foil winding machine for superconducting wire preparation. Background technique [0002] Superconductivity is the property of a metal or alloy in which the electrical resistance becomes zero at lower temperatures. In addition to the zero-resistance property, superconducting materials also have unique properties that many conventional materials do not have, such as complete diamagnetism and macroscopic quantum effects. Using these properties of superconductors can transmit large currents, obtain strong magnetic fields, etc., so superconducting materials have important applications in many fields. Bi-based materials are one of the important materials in superconducting materials. How to prepare high-performance superconducting wires has become a research hotspot in various scientific research institutions in recent years. Coiling...
