Abstract
The utility model relates to a laser cladding device, in particular to a coaxial protective gas conveying device for laser cladding. According to the technical scheme, the coaxial protective gas conveying device comprises an outer sharp-nose tube, an inner sharp-nose tube, a flow divider, an air inlet and a tail tube, wherein the inner sharp-nose tube is sleeved with the outer sharp-nose tube; the outer sharp-nose tube and the inner sharp-nose tube are respectively connected with one end of the flower divider; an air inlet and a plurality of air outlets are formed in the flow divider; the other end of the flow divider is connected to a laser device through the tail tube. The coaxial protective gas conveying device has the benefits as follows: coaxial gas protection is introduced in the cladding process, a molten pool can be protected by inert gas, and the burning loss of additional elements in a cladding layer is reduced, so that more additional elements in powder can enter the cladding layer, and thus the performance of the cladding layer is ensured; moreover, the cladding layer can also be protected by the inert gas in the solidification process, so that the surface oxidation of the cladding layer is prevented, and attractive appearance of forming is ensured.
Description
Technical field
The utility model relates to a kind of laser cladding apparatus, particularly a kind of laser cladding coaxial protection gas e Foerderanlage.
Background technology
Laser melting and coating technique refers to places the coated material of selecting on coated matrix surface with different adding material modes, make it to melt with matrix surface thin layer through high energy laser beam simultaneously, and it is extremely low after rapid solidification, to form thinning ratio, become the top coat of metallurgical binding with body material, thereby significantly improve the technique of wear-resisting, anti-corrosion, heat-resisting, oxidation-resistance of substrate material surface etc.Laser melting coating is as a kind of emerging technology of field of surface engineering technique, is metallurgical binding, organizes the advantage of many uniquenesses such as superfine, cladding layer thinning ratio is low, and thickness is controlled, heat distortion is little because it has interface, become more active research field.In Laser Cladding Treatment process, sometimes need molten bath to carry out protection of inert gas, prevent the interference of oxygen to cladding process in air, thereby ensure the superperformance of cladding layer.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, a kind of easy and simple to handle, environmental protection is provided and does not affect the laser cladding coaxial protection gas e Foerderanlage of laser processing.
Its technical scheme is: comprise sharp mouth outer tube, sharp mouth inner tube, splitter, inlet mouth, tail pipe, described sharp mouth outer tube inner sleeve has sharp mouth inner tube, described sharp mouth outer tube is connected with one end of splitter respectively with sharp mouth inner tube, splitter is provided with an inlet mouth and multiple air outlet, and the other end of splitter is connected to laser apparatus by tail pipe.
Above-mentioned splitter comprises inner housing, body skin and air outlet, between described inner housing and body skin, forms annular cavity, connects inlet mouth in a side of body skin; In annular cavity between inner housing and body skin, be provided with one and iris out gas port, described air outlet is connected to the cavity between sharp mouth outer tube and sharp mouth inner tube, makes gas convert ring dress air-flow to.
The beneficial effects of the utility model are: in cladding process, introduce coaxial gas protection, can make molten bath in protection of inert gas, reduce the scaling loss of adding element in cladding layer, make the cladding layer that enters into that interpolation element in powder can be more, thereby ensure the performance of cladding layer; And cladding layer also can be subject to protection of inert gas in process of setting, prevent cladding layer surface oxidation, ensure that moulding is attractive in appearance.
