Curve cutting machine for amorphous alloy strips

Abstract

The invention relates to a curve cutting machine for amorphous alloy strips. The curve cutting machine comprises a strip discharging zone, a shearing zone and a strip collecting zone which are sequentially arranged. The strip discharging zone comprises a strip discharging servo motor, a hoisting device and a strip discharging zone pressure sensor, and the rolled amorphous strips are arranged on the hoisting device and can be driven by the strip discharging servo motor to rotate so as to be discharged; the shearing zone comprises a servo motor, a cutting blade group, a cutting sliding table, a speed sensor, a rubber wheel pressure group, an absorption worktable, a displacement worktable, a displacement table feeding system and a pressure regulating mechanism; the strip collecting zone comprises strip collecting servo motors, strip collecting wheels, strip collecting zone pressure sensors and a positioning clamp plate. The curve cutting machine has the advantages that the amorphous alloy strips can be conveyed under the linkage effects of the multiple groups of servo motors, can be shorn and machined in the shearing zone and can be wound and collected in the strip collecting zone after being shorn; requirements on transversely and longitudinally shearing the amorphous alloy strips can be met by the cutting machine which is applicable to the amorphous alloy strips.

Description

technical field [0001] The invention relates to the field of mechanical processing, and more particularly, to a curve cutting machine for amorphous alloy strips. Background technique [0002] Compared with crystalline alloys, amorphous alloys have undergone significant changes in physical, chemical and mechanical properties. Amorphous alloys dominated by iron have the characteristics of high saturation magnetic induction and low loss. Due to these characteristics, amorphous alloys have broad applications in electronics, aviation, aerospace, machinery, microelectronics and many other fields. application space. The preparation of amorphous alloys adopts a rapid solidification process. High-temperature molten steel in a molten state is sprayed onto a high-speed rotating cooling roll. The molten steel at 1300°C is lowered to below 200°C within the same time to form an amorphous strip. [0003] Compared with ordinary silicon steel sheet transformers, amorphous alloy transforme...

Problems solved by technology

However, due to the high hardness of the amorphous alloy strip (about 5 times that of the silicon steel sheet, difficult processing), easy transverse tearing during longitudinal shearing and transmission, and high brittleness, and other processing bottlenecks, and the existing silicon steel sheet three-dimensional wound core production The equipment cannot meet the manufacturing requirements of the amorphous alloy three-dimensional wound core, which greatly limits the field application and market promotion of the amorphous alloy transformer
