Abstract

The invention discloses an induction heating auxiliary drawing device for preparing a capillary tube. The induction heating auxiliary drawing device comprises an induction heating device, a drawing mold, a vibration generator and a cooler. The drawing mold is provided with a shaft hole for the capillary tube to pass through before drawing. The induction heating device is arranged on one side of the shaft hole, and the vibration generator is installed on the outer surface of the drawing mold. The cooler is arranged on the other side of the shaft hole relative to the induction heating device, and the induction heating device, the drawing mold and the cooler are coaxially and oppositely arranged. The deformation temperature of the tube is increased through the induction heating device, and the plasticity of the tube is improved, so that the pass deformation is finally increased and the drawing pass is reduced; meanwhile, an ultrasonic vibration device enables the mold to vibrate, improves the friction condition and reduces the drawing force, finally, the pass deformation can be increased, the drawing pass can be reduced, and large-deformation drawing of the capillary tube is achieved through the multi-energy-field combined auxiliary drawing device.

Description

technical field [0001] The invention relates to the field of capillary material preparation, in particular to an induction heating assisted drawing device for preparing capillary. Background technique [0002] Capillary, a tube with an outer diameter of less than 3.0mm and a wall thickness of less than 0.80mm, plays an extensive and irreplaceable role in military, medical, optoelectronic and other fields. Compared with rolling and extrusion, the drawing process is the most suitable production process for preparing capillary tubes. However, in the process of drawing from the tube blank to the capillary, the total deformation is close to hundreds of times. When the traditional drawing process faces such a large amount of deformation, a large number of drawing passes and intermediate annealing processes are required, which seriously affects the production efficiency. Therefore, it is necessary to design a new drawing device to improve production efficiency. [0003] At prese...
