Problems solved by technology

However, the electroplastic effect is currently applied mainly to wire materials, and there is no report on thin-walled capillaries. It is necessary to conduct current-assisted thin-walled capillary pull-out tests to study the influence of electroplastic effects on it.
[0004] For the electric-assisted drawing power-on device, the invention patent "A preparation method of amorphous alloy wire and electric drawing device" with the application publication number CN106807799A does not explain the specific power-on device; the invention patent with the application publication number CN102489533B Although the patent "An Electroplastic Drawing Device and Drawing Method for MgB2 Wire Rod" proposes an electrification device, due to the thin wall thickness and small diameter of the thin-wall capillary, the electrification device will cause the thin-wall capillary to generate Plastic deformation, so it cannot be applied to the electric-assisted drawing of thin-walled capillaries

Abstract

The invention discloses a device and method for loading current to a thin-wall capillary tube during electric auxiliary drawing. The device comprises a cable fixing device and an electrode contact device. A cable is rigidly fixed through the cable fixing device so as to be prevented from slightly moving along with the capillary tube in an electric auxiliary drawing process. Meanwhile, stable contact between an electrode and the capillary tube is guaranteed through the electrode contact device, so that excessive test errors caused by the change of the density of current loaded onto the capillary tube in the electric auxiliary drawing process are prevented, and the current can be stably and effectively loaded onto the capillary tube in the drawing process.

Description

technical field [0001] The invention belongs to the field of metal material forming and processing, and in particular relates to a thin-walled capillary electrically assisted drawing and charging device and method. Background technique [0002] Thin-walled capillary tubes are widely used in refrigeration equipment such as refrigerators and air conditioners, and have excellent characteristics such as high pressure resistance, high heat resistance, light weight, and high reliability. However, the traditional manufacturing process cannot solve the technical problems of difficult processing, poor dimensional accuracy, and unstable performance of thin-walled capillary tubes, so that the dimensional accuracy, microstructure, surface finish, comprehensive mechanical properties and production efficiency of thin-walled capillary tubes cannot be guaranteed. . [0003] Introducing the action of electricity into the forming process of the material can significantly reduce the deformati...
