Embodiment 1

[0042] Production of high nitrogen steel wire

[0043] A preparation method based on a heating-drawing-finishing shaping-cooling wire device is used to produce high-nitrogen steel wire, and the specific steps are as follows:

[0044] The first step, according to the diameter Φ of the material to be drawn 0 and the diameter of the target wire Φ 目标 , choose the aperture as Φ 1 , Φ 2 、Φ 3 ,...,Φ n The drawing die and fine drawing shaping mechanism, where Φ 0 >Φ 1 >Φ 2 >Φ 3 >…>Φ n = Φ 目标 , and Φi —Φ i+1 ≤ξ·Ψ·Φ i , (i=0,1,2...n-1), where ξ is a constant, generally 0.2 to 0.6, Ψ is the reduction of area of ​​the material, and n is the number of wire drawing.

[0045] The high nitrogen steel preheating temperature range is 300°C to 500°C, and nitrogen is used as the protective gas.

[0046] Determine the preheating temperature range and the type and ventilation rate of the protective gas according to the type of wire drawing material. For the wire material that is easy ...

Embodiment 2

[0053] Production of copper wire

[0054] The difference from Example 1 is that the copper wire has a relatively high requirement for temperature control during the drawing process. At the same time, the required shielding gas is also different, and argon is used here as the shielding gas.

[0055] Adopt a kind of preparation method based on heating-drawing-finish drawing shaping-cooling wire material device to produce copper wire, comprise concrete steps as follows:

[0056] The first step, according to the diameter Φ of the material to be drawn 0 and the diameter of the target wire Φ 目标 , choose the aperture as Φ 1 , Φ 2 、Φ 3 ,...,Φ n The drawing die and fine drawing shaping mechanism, where Φ 0 >Φ 1 >Φ 2 >Φ 3 >…>Φ n = Φ 目标 , and Φ i —Φ i+1 ≤ξ·Ψ·Φ i , (i=0,1,2...n-1), where ξ is a constant, generally 0.2 to 0.6, Ψ is the reduction of area of ​​the material, and n is the number of wire drawing.

[0057] The preheating temperature range of the copper wire is 25...

Abstract

The invention discloses a heating-wiredrawing-finish drawing shaping-cooling wire preparing method and device. The device mainly comprises an induction heating mechanism, a wiredrawing die, a finish drawing shaping machining mechanism, a cooling mechanism, a protection gas trough and a sealing ring. The wiredrawing device is suitable for manufacturing of high-strength welding wires and metal wires. Non-contact type induction heating is adopted, wires (or wire rods) to be drawn can be rapidly heated to a certain temperature, the ductility and toughness of the wires are improved, and wiredrawing is facilitated. The device can provide gas protection, and oxidation of the wires during heating and drawing is effectively prevented. The functions such as induction heating, wiredrawing, finish drawing shaping and structure control are integrated into the wire preparing method.

Description

technical field [0001] The invention belongs to the technical field of wire material preparation, and specifically relates to a heating-wire drawing-finish drawing shaping-cooling wire material preparation method and device, which are suitable for the production of high-strength difficult-to-draw welding wires and metal wires and other wire materials. Background technique [0002] During the drawing process, due to its high strength and hardness, high-strength welding wire is prone to problems such as brittle fracture, uneven thickness, and damage to the extrusion die. At the same time, multiple times of drawing are required to obtain a welding wire with a certain diameter, and the production efficiency is low. However, the present invention can provide induction heating and fine drawing and shaping functions, can heat the bar to the required temperature in a short time, improve the plasticity and toughness of the bar, and also reduce the friction damage of the bar to the ex...
