Sneer use coalesce type capillary drawing formation system

摘要

The present invention provides better and more robust drawing quality when drawing integrated capillary tubes (refrigerant pipes), as well as noises, cracks, cracks, etc. due to rough inner walls, which have high internal roughness. In addition, the present invention relates to an integrated capillary drawing apparatus for a refrigerant provided with a production cost reduction effect due to a simpler and simplified structure / process.;That is, the inner diameter guide portion 201 for guiding the inside diameter of the large diameter copper pipe P, which is a drawing material, is inserted into one end of the inlet side of the die 100 formed in the capillary drawing molding apparatus A, and the guide portion thereof. An inclined guide portion 202 for gradual and smooth guiding when the large diameter copper pipe guided to the tip of the 201 is drawn to a smaller diameter, and a large diameter copper pipe at the end of the inclined guide portion 202. Is to install the inner diameter jig bar 200 for drawing the pipe is composed of the inner diameter support 203 that can securely hold / maintain the inner diameter when drawn / molded into a small diameter capillary pipe.;Drawing die, drawing groove, pipe slope guide groove, drawing molding groove, drawing inner diameter jig bar, inner diameter guide part, inclined guide part, inner diameter support part
