[0060]

[0061] The low-temperature ultrasonic rolling impact device used is such as figure 1 , figure 2 , image 3 and Figure 4 As shown,

[0062] The device includes a closed liquid cooling temperature control mechanism, a traction transmission mechanism and an ultrasonic rolling impact mechanism;

[0063] The airtight liquid cooling temperature control mechanism includes an airtight container 4 containing a cooling liquid 7 inside. The outer shell of the airtight container 4 has a double-layer structure, and the inner layer is an insulating layer made of an insulating material; the airtight container 4 The two opposite sides in the length d...

Embodiment 2

[0080] The 304 austenitic stainless steel wire rod with a width and thickness of 300 μm was subjected to a multi-pass liquid-cooled temperature-controlled ultrasonic rolling continuous impact treatment, and the low-temperature ultrasonic rolling impact device was the same as that in Example 1.

[0081] The above-mentioned ultrasonic transducer 3 converts the electric oscillation into 20kHz ultrasonic, the ultrasonic horn further amplifies the amplitude, and drives the GCr15 bearing steel rigid impact roller 11 on the top of the ultrasonic tool head 12 (diameter 6mm, width 10mm; surface groove width 300μm, Depth 1mm; surface roughness (Ra): 0.1μm, hardness: 64HRC) produce longitudinal high frequency vibration; use laser displacement sensor to measure the vibration amplitude, the end amplitude is 30μm; the ultrasonic horn is fixed to impact the rigid roller The distance between 11 and the rigid roller 8 is the sum of the ultrasonic amplitude and half the thickness of the wire, that ...

Abstract

The invention discloses process method and device for high-performance wire rod production, and belongs to the technical field of severe plastic deformation fine grains. The process method can obtaina finished product with an invariable section size through the steps of material selection and cleaning, ultrasonic impact strengthening treatment preparation, ultrasonic impact strengthening treatment, two-piece welding and multi-pass rolling treatment, and a finished product with a uniformly thinned section size can be obtained after one-time ultrasonic impact strengthening treatment; and a low-temperature ultrasonic rolling impact device comprises a closed container filled with cooling liquid, an ultrasonic transducer, an ultrasonic tool head, a rigid impact roller column, an ultrasonic power supply, a rigid roller, a roller driving motor, a pressure cylinder, a spring and a traction transmission mechanism. According to the process method, uniform and efficient grain refinement can be realized on a wire rod or a strip with the micron-sized thickness, and the comprehensive mechanical property of the material is obviously improved; and the device can realize the low-temperature ultrasonic impact SPD strengthening treatment of the wire rod or the strip and can meet requirements of two impact treatment modes.

Description

Technical field [0001] The invention relates to the technical field of Severe Plastic Deformation (SPD) fine crystals, and in particular to a high-performance wire production process method and device for ultra-fine metal wires or ultra-thin strips. Background technique [0002] Sever Plastic Deformation (SPD) has great potential to refine the grains of coarse-grained materials to the nanometer level. It is a unique ultra-fine crystal (nanocrystalline or submicron) that has gradually developed in recent years. Crystal) metal and its alloy material preparation process. It means that the material is at a lower temperature (usually lower than 0.4T m ) In the environment, severe plastic deformation occurs under the action of large external pressure, so as to refine the grain size of the material to a sub-micron or nano-level process. Strong strain and large plastic deformation can significantly refine the microstructure of metal materials under low temperature conditions, thereby gr...
