Abstract
The present invention relates to a preparation method of a resistance spot welding electrode. The technology method comprises the following steps: firstly, fine copper powder is mixed with superfine aluminium oxide powder by a mechanical alloying method; secondly, the mixture is manufactured into a cylindrical blank by cold pressing; thirdly, the blank is cast into chromium-zirconium-copper to obtain a composite cast ingot; finally, the cast ingot is processed by a hot extrusion method to obtain a rod material, so the chromium-zirconium-copper rod material containing dispersed and reinforced copper is obtained. The extruded chromium-zirconium-copper rod material with dispersed and reinforced copper in the centre replaces traditional chromium-zirconium-copper rod materials, and is used as a resistance spot welding electrode. The present invention has the advantages of simple technology method and easy production. In the present invention, a large amount of chromium-zirconium-copper material is saved, the time of repairing and renewing electrodes in the production lines is saved, and production efficiency is greatly improved.
Description
The present invention relates to a kind of making method of resistance welding electrode material.
At present, electrode materials be manufactured with several different methods, there is the mechanical alloying of employing method to make the oxide dispersion intensifying material, also there is employing that the oxide dispersion intensifying copper billet is set in copper matrix head in the prior art and makes the resistance welding material, the shortcoming of this method is that fine copper matrix hot strength is poor, the inlay complexity is unsuitable for big industrial production, so production cost is higher.
For solving the deficiency of above producing and manufacturing technique, the invention provides a kind of continuous rod material production technology method of chromium zirconium copper that contains oxide dispersion intensifying copper with central part, utilize between oxide dispersion intensifying copper and the body material chromium zirconium and form metallurgical binding, to reach the bonding strength height, the resistance to elevated temperatures of outer chromium zirconium copper is good, is fit to big industrial purpose.
Technical scheme of the present invention is achieved in that at first spot-wedling electrode is for casting the powder green bodies of oxide dispersion intensifying copper at chromium zirconium copper central part, must arrive the continuous bar of chromium zirconium copper that oxide dispersion intensifying copper is contained at the center by hot extrusion then, its processing method is illustrated in conjunction with the embodiments, at first granularity is carried out pre-mixing less than the atomized copper powder of 75 μ m and aluminum oxide powder less than 3 μ m, then with the powder that mixes ball milling 3～4 hours in high energy ball mill, the powder that mill is good is cold-pressed into φ 70mm in punching block, the base substrate of high 150mm, this base substrate is placed on φ 180mm, in the chromium zirconium casting in bronze ingot mould of high 340mm, in vacuum oven, smelt chromium zirconium copper, Cu content 0.6%, Zr content 0.3%, the alloy of smelting is cast in ingot mould, carry out surface-conditioning after the demoulding, the ingot casting that cleaning is good is heated to 850 ℃ of insulations 2 hours, be hot extruded into the bar of φ 38mm then, this bar is heated to 980 ℃ of insulations 2 hours, shrend then, this is for outer field chromium zirconium copper is carried out solution treatment, after the solution treatment bar is cold-rolled to the bar of φ 16mm, again these bars are heated to 480 ℃ of insulations 4 hours, cladding material is carried out ageing treatment, and this bar direct mechanical is processed into spot-wedling electrode.
Advantage of the present invention: the chromium zirconium copper rod that has oxide dispersion intensifying copper with this kind extruding heart portion has replaced the chromium zirconium copper bar material of traditional use to do resistance welding electrode, processing method is simple, make easily, can save a large amount of chromium zirconium copper products, also can save the time of production line, improve production efficiency greatly because of reconditioning and replacing electrode.
