Problems solved by technology

According to the current sales price, even the best quality stainless steel wire is sold at 1300 yuan / kg, and the defective product is 1000 yuan / kg, so the mold fee is 900 yuan and it will lose money. Almost no factories are willing to take this kind of work. The reason is that the cost is too high, the input and output are out of proportion, and there is no profit at all.

Embodiment 1

[0008] Embodiment 1: colored stainless steel ultrafine wire production process, it comprises stainless steel microwire process and stainless steel wire drawing machine, described stainless steel ultrafine wire drawing process is on the basis of stainless steel wire drawing process: (1) raw material selection: select φ0. 2mm stainless steel wire is used as raw material and drawn to φ0.035mm by a stainless steel wire drawing machine, as a billet wire drawn from φ0.018mm to 0.015mm; The inner diameters of the drawing dies are 0.030, 0.027, 0.025, 0.023, 0.021, 0.020, 0.019; , the billet is drawn through the above-mentioned set die and forming die to obtain microfilaments. (3) The microfilament passes through the high-temperature oxidizing atmosphere at a speed of less than 10 meters per second, and a transparent film with a thickness of tens to hundreds of nanometers is formed on the surface of the microfilament. Films with different thicknesses and different compositions present...

Abstract

The invention relates to a production process of colored stainless steel microwires capable of drawing φ0.018mm stainless steel microwires, which includes a stainless steel wire drawing machine, and raw material selection: select φ0.2mm stainless steel wires as raw materials and draw them to φ0.035mm by the stainless steel wire drawing machine , as a blank wire drawing φ0.018mm~0.015mm; mold matching: a set of multiple wire drawing dies is matched with the forming die, and the inner diameters of the multiple wire drawing dies are 0.030, 0.027, 0.025, 0.023, 0.021, 0.020 , 0.019; Or 0.030, 0.027, 0.025, 0.023, 0.021, 0.020, 0.019, 0.018, 0.017, 0.016, the inner diameter of the forming die is 0.018 or 0.015, and the blank wire is drawn to obtain microfilaments through the above-mentioned cover die and forming die. The microfilaments pass through the high-temperature oxidizing atmosphere at a speed of less than 10 meters per second, and a transparent film with a thickness of tens to hundreds of nanometers is formed on the surface of the microfilaments. Films with different thicknesses and different compositions present different colors.

Description

technical field [0001] The invention relates to a production process of colored stainless steel superfine wires capable of drawing φ0.018mm stainless steel microwires, belonging to the field of stainless steel wire drawing technology. Background technique [0002] At present, the stainless steel wire drawing process is very serious due to the improper ratio of the mold matching. For example, if a 100g stainless steel wire is drawn at a time, it will be repaired almost once every time it is drawn. For wire drawing, a mold is 180 yuan, and the mold fee for 1kg stainless steel wire is 600 yuan. If it is out of tolerance for the second repair, it can only be pulled twice. The mold fee for 200g and 1kg stainless steel wire is 900 yuan. According to the current sales price, even if the best quality stainless steel wire is sold at 1300 yuan / kg, the defective product is 1000 yuan / kg, so the mold fee is 900 yuan and it will lose money. Almost no factories are willing to take this ki...
