Current, as the ceaseless development of mould industry and application. And the product rises ceaselessly to the requirement of the mould, mould investment uses more and more high end nicety, in the use process with ceaseless mould, inevitable conference appears the harm to the mould, such as wears away, cut, pinhole, crackle and be short of the blemish such as caustic. Traditional repair equipment another decides degree to go up, help client has repair to the mould with managing cost. But inevitable also occurrence a few problems, if the pattern is created after repair mould,be out of shape, hardness is reduced, internal stress, trachoma, injury discards as useless even. Our company product nicety model repairs cold welding plane, it is to use principle of discharge of high frequency electric spark, undertake notting have heating up v to the mould, in order to assure the in good condition sex of the mould, also can use aggrandizement function to undertake to the mould aggrandizement is handled, the wearability that will realize a mould, hear resistance, be able to bear or endure corrode sex is waited a moment. Facility work principle is become electrode club (welding rod) rotate in working surface, when certain place clearance very hour, make loop of lead plane discharge forms access. The small area instantaneous that contacts each other in them has shed electric current, current density can achieve 105~106/cm2, and discharge time only 10-6~10-5 second, because put electric energy to go up to be centered highly with the space on time, arose to make an appointment with the high temperature of 8000~10000 ℃ inside the area with small discharge, make the local material of this area high-energy ionization, electrode club (welding rod) below plasma metallurgy condition high speed changes workpiece face, diffuse enter workpiece surface layer, form the deposit layer of metallurgy firm union. Cycle of discharge of lead plane power source is 10-3~10-1 second, high-frequency discharge and electrode club (welding rod) rotate in the high speed of workpiece surface scanning, can realize bedding face to accumulate efficient deposit coating. Why can you come true " cold welding " (is hot input low) ? Because discharge,this is time (Pt) than discharge time interval (It) short, quantity of heat is rapid during discharge is removed diffuse the other part of workpiece, because this quantity of heat won't be centered in the processing part of workpiece, realize the cold welding of real significance. Why to combine strength tall? Electrode club (welding rod) the instant is transferred by electric arc ionization above the workpiece that contacts with its, give the high temperature with plasma electric arc at the same time (8000-10000 ℃ ) form below workpiece surface layer be like dish of solid diffusion layer like section following a fault, because this union strength is high,won't fall off. Exact pattern repairs characteristic of equipment of cold welding aircraft: ¤ equipment is advanced and reliable, german mainland technology, argon gas protects international level high-power, can work for long. ¤ rotates type from caustic electrode, efficiency of deposit, v is tall, metallurgy union, coating is qualitative close. One machine of ¤ is multi-purpose, can have the function such as aggrandizement of v deposit, surface. Through adjusting the spark voltage of equipment, with discharge frequency, the ply that can obtain the v that must beg or aggrandizement coating and bright and clean degree. ¤ operates simple, low hot input, when the mould is repaired beardless warm-up, the instant of v does not have hot input in the process, consequently the mould is not out of shape, not anneal, bite edge and leftover stress, do not change mould or position of product metal organization. ¤ electrode origin is wide, economy is practical. ¤ applicable base material is wide, include tungsten alloy of alloy of aluminium of steel of steel of mild steel, medium carbon steel, mould, stainless steel, tool, cast-iron, cast steel, casting, aluminium alloy, copper alloy, nickel, carbon to wait, and all OK and electric electric system. Sex of ¤ environmental protection, any pollution are not had in working process. ¤ economy, but the spot is online repair, improve manufacturing efficiency, save time and cost. ¤ rehabilitate precision is tall, coating ply arrives from a few micron a few millimeter, simply burnish, polish. Also can have car, mill, planing machine, grind wait for of all kinds machining, and eletroplate wait for later period treatment. CNC Milling
