Problems solved by technology

The presence of welds leads to problems such as cracks and high wire breakage during the drawing and forming process of double metal wires, especially for the continuous manufacturing of small-sized wires (diameter less than 3mm), and this manufacturing method is also difficult to achieve large-scale continuous production
[0006] Moreover, for the processing of bimetallic composite wire, most of them currently use a single processing and manufacturing technology, and no continuous processing method from blank to wire has been found.

Embodiment 1

[0030] This embodiment relates to a continuous mixing manufacturing method of a bimetallic composite wire, comprising the following steps:

[0031] 1) Blank material selection. In this embodiment, the core material is 65Mn steel, the size is 1.6m long, and the diameter is 20mm; the stainless steel casing is 304 stainless steel, the inner diameter of the stainless steel casing is 21mm, the tube thickness is 5mm, and the length is 1.62m. After cleaning the surface of the core material 65Mn steel and the inner side of the stainless steel casing, the core material is implanted inside the stainless steel casing, and one end is lightly forged to make the core steel and the surface stainless steel tightly bonded, not easy to fall off, and ensure that the 65Mn steel is placed in the center of the 304 stainless steel tube .

[0032] 2) The billet is formed by hot swaging. Put the blank in a heating furnace and heat it to 100°C-550°C, preferably 150°C-450°C. In this embodiment, heat i...

Embodiment 2

[0036] 1) Blank material selection and processing. In this embodiment, the core material is No. 35 steel, the size is 1.6m long, and the diameter is 16mm; the stainless steel sleeve is 304 stainless steel, the inner diameter of the stainless steel sleeve is 17mm, the tube thickness is 4mm, and the length is 1.62m. After cleaning the surface of the core material No. 35 steel and the inner side of the stainless steel sleeve, implant the core material into the stainless steel sleeve, and one end is slightly forged to make the core steel and the surface stainless steel sleeve tightly fit, not easy to fall off, and ensure that the No. 35 steel is placed 304 stainless steel tube center.

[0037] 2) The billet is formed by hot swaging. Place the blank in a heating furnace and heat it to 100°C-550°C, preferably 150°C-450°C. In this embodiment, heat it to 200°C and keep it warm for 3 minutes. The total area reduction rate is 1%-99%, preferably 50%-99% %, swaging forming, the 304 stai...

Abstract

The invention relates to a continuous mixing manufacturing method from a blank to a bimetal composite wire. The method comprises the following steps: step 1, selecting and treating a blank material, wherein metal oxide layers and the like on the outer surface of a core material and the inner wall of a sleeve are cleaned and dried, the core material is implanted into the sleeve, and one end of thecore material is slightly forged to enable the core material to be tightly attached to the sleeve; step 2, processing the blank, wherein the heating temperature is selected according to the metal of the composite wire, the bimetal composite blank is heated, a bar with the small diameter is manufactured through a single-pass or multi-pass hot rotary forging process, and the single-pass rotary forging area reduction rate ranges from 1% to 99%; step 3, performing primary continuous hot rolling forming, wherein the bar processed in step 2 is processed into a wire rod with a certain specification diameter through a hot rolling forming technology; and step 4, carrying out heat treatment on the wire rod formed by hot rolling forming, and carrying out cold drawing forming by a mold. The method caneasily realize large-scale production of continuous manufacturing from the blank to the double-metal-wire wire rod.

Description

technical field [0001] The present invention relates to a continuous hybrid manufacturing method from billet to bimetallic composite wire. It belongs to the technical field of metal product processing. Background technique [0002] Bimetal composite wire has gradually become a development trend in the field of metal wire products due to its advantages in good mechanics, efficient use of surface material properties, and material cost. [0003] At present, the processing of bimetallic composite wire is mainly hot-extruded and coated followed by drawing, such as the processing of aluminum-clad steel wire, copper-clad aluminum wire, etc. For the processing of bimetallic rods, hot extrusion is often used. For some materials with small difference in melting point of metal materials, such as stainless steel / carbon steel bimetallic wire, aluminum alloy / magnesium alloy wire, it is difficult to process by hot extrusion coating technology. [0004] Applying for an invention patent "a...
