The mould has all in all effect in modern industry, its quality decides the quality of the product directly. Raise the service life of the mould and precision, shorten the production of the mould is periodic, it is the technical issue that a lot of enterprises are badly in need of solving, but in the mould regular meeting of the classics in use process appears collapse horn, be out of shape, wear away, break off even wait for invalidation form. Accordingly, also be necessary to the rehabilitate of the mould. The method of repair mould is very much, be like method of plating of technology of v of rehabilitate of solder of arc of electric spark craft, argon, laser, brush. Flaming electric arc makes heat source between the welding wire that repair uses argon arc solder to send continuously and workpiece, by solder fire nozzle ejective gas protects electric arc to undertake soldering. At present argon arc solder is commonly used method, applicably at major main metal, include carbolic steel, alloy steel. Extremely fused solder of inert gase protection applies to stainless steel, aluminous, magnesian, copper, titanium, zirconium and nickel alloy, because the price is low, be used extensively at mould rehabilitate solder, but solder big, solder nods hot influence area to wait for defect greatly, revamp a side in exact pattern at present progressively already filling laser beam welding is replaced. Technology of plating of brush of brush plating rehabilitate is to use device of a kind of special direct current source, the anode of power source receives plating pen, the negative pole that regards the zincous; when brushing plating as power source receives work, as the cathode when brushing plating.

Plating pen is used normally high pure thin black lead piece as zincous material, wrap outside black lead piece on the cleanse a cotton-padded covering for keeping sth warm of cotton and wear-resisting.

When the job, power source component adjusts appropriate voltage, the plating pen that makes invade full plating fluid is in with fixed opposite motion rate be come up to wind campaign by repair work surface, maintain constant pressure, till the metallic deposit that forms even ideal till the layer.

As a result of plating pen and the place that are contacted by repair work surface, the metallic ion in plating fluid diffuses below the action of electric field force workpiece apparently, in apparently obtain an electron reductive into metallic atom, thereby crystallization of these metallic atom deposit form film, be in namely by the even deposit layer that repair obtains a need on working face of plastic mould antrum.

Laser beam welding of laser v rehabilitate is the laser that uses monochromatic of high-power be concerned with to photon sheds focusing and be become bundle solder for what heat source undertakes. This kind solders the method has permanent power laser beam welding and pulse power laser beam welding normally. Advantage of laser beam welding is not to need to undertake in vacuum, defect is penetration not as strong as electron beam solder. Can undertake accurate energy is controlled when laser beam welding, can realize rigid parts of an apparatus consequently solder. It can apply at a lot of metals, can solve what metal of a few difficult solder reachs heterogeneous metal to solder especially. At present wide already model the rehabilitate that is used at the mould. CNC Milling CNC Machining
