Abstract

The utility model discloses laser melting coating sand target, it includes covering on target shell and target handle, the inwall of the target shell and forms laser cladding layer；The inwall covering of the sand target forms the laser cladding layer, that is, the inwall of the sand target has all carried out Laser Cladding Treatment, so that its inwall is all formed with the laser cladding layer, so as to improve the performances such as wear-resisting, anti-corrosion, heat-resisting, the anti-oxidant and electrical characteristic of inwall of the sand target；So that the inwall of the sand target has good anti-wear performance, the service life of the target shell is improved.

Description

Laser melting coating sand target

Technical field

The utility model is related to laser technology field, more particularly to a kind of laser melting coating sand for being related to laser melting and coating technique Target.

Background technology

Laser melting coating（Laser Cladding) laser cladding or laser cladding are also known as, it is that a kind of new surface is modified skill Art；It refers to that selected coating material is placed on by cladding matrix surface with different adding material modes is allowed to through laser irradiation Melted simultaneously with matrix surface a thin layer, and formation dilution factor is extremely low after rapid solidification, is applied with matrix into the surface of metallurgical binding Layer, significantly improves wear-resisting, anti-corrosion, heat-resisting, anti-oxidant and electrical characteristic the process of substrate surface, so as to reach that surface changes Property or the purpose of reparation, had both met the requirement to material surface particular characteristic, cost have been saved again；With built-up welding, spraying, plating With gas phase sedimentary facies ratio, there is laser melting coating small dilution factor, dense structure, coating and matrix to be combined, suitable cladding material is more, The features such as granularity and big changes of contents, therefore laser melting and coating technique application prospect is very wide.

Sand target is used for sand preparing machine or production, cleaning and the powder collection for reclaiming each operation of other powder body materials, by In substantial amounts of abrasive wear for a long time, sand target easily wear out failure is caused..

Therefore, now provide a kind of anti-wear performance good laser melting coating sand target.

Utility model content

Therefore, a kind of laser melting coating sand target is now provided, and laser melting coating sand target of the present utility model, it includes target shell and target Covering forms laser cladding layer on handle, the inwall of the target shell.

The target shell includes conical section and cylindrical portions, and the target handle is fixedly connected with the outer wall of the conical section.

Through hole is formed on the target handle.

The thickness of the target handle is more than the thickness of the target shell.

The laser cladding layer is spliced by some laser melting coating circles.

Surface molten solidifying shape of the laser melting coating circle by cladding material under laser melting coating effect with the inwall of the target shell Into.

The laser melting coating is set to presetting system or synchronous mode laser melting coating.

The cladding material is set to antifriction alloy powder.

The thickness H of laser cladding layer value range is met：1.5≤H≤3.0mm.

The hardness of the target shell is not less than HRC50.

Above-mentioned technical proposal of the present utility model has advantages below compared with prior art：

In the utility model, the inwall covering of the sand target forms the laser cladding layer, that is to say, that the sand The inwall of target has all carried out Laser Cladding Treatment so that its inwall is all formed with the laser cladding layer, so as to improve described The performances such as wear-resisting, anti-corrosion, heat-resisting, the anti-oxidant and electrical characteristic of the inwall of sand target；So that the inwall of the sand target has well Anti-wear performance, improve the service life of the target shell.

Brief description of the drawings

In order that content of the present utility model is more likely to be clearly understood, below according to specific implementation of the present utility model Example and with reference to accompanying drawing, the utility model is described in further detail, wherein

Fig. 1 is laser melting coating sand target schematic diagram described in the utility model；

Fig. 2 is laser melting coating sand target sectional view described in the utility model；

Reference is expressed as in figure：1- target shells；2- target handles；3- laser cladding layers；4- through holes.

Embodiment

Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.It should be appreciated that herein Described embodiment is merely to illustrate and explained the utility model, is not limited to the utility model.

As illustrated in fig. 1 and 2, the laser melting coating sand target of the present embodiment, it includes target shell 1 and target handle 2, the target shell 1 it is interior Covering forms laser cladding layer 3 on wall.

In the present embodiment, the inwall covering of the sand target forms the laser cladding layer 3, that is to say, that the sand The inwall of target has all carried out Laser Cladding Treatment so that its inwall is all formed with the laser cladding layer 3, so as to improve described The performances such as wear-resisting, anti-corrosion, heat-resisting, the anti-oxidant and electrical characteristic of the inwall of sand target；So that the inwall of the sand target has well Anti-wear performance, improve the service life of the target shell 1.

Specifically, the target shell 1 includes conical section and cylindrical portions, the target handle 2 and the outer wall of the conical section It is fixedly connected；Through hole 4 is formed on the target handle 2, the thickness of the target handle 2 is more than the thickness of the target shell 1.

Further, the laser cladding layer 3 is spliced by some laser melting coating circles；For example, in the present embodiment, it is described Laser cladding layer 3 includes N number of laser melting coating circle, and the width of the laser cladding layer 3 is set to L to length, then described in each The width of laser melting coating circle is L/N.

On the basis of above-described embodiment, the laser melting coating circle by cladding material laser melting coating effect under with the target The surface cladding of the inwall of shell 1 is formed, and the laser melting coating is set to presetting system or synchronous mode laser melting coating, and the cladding material is set For antifriction alloy powder；I.e. in the present embodiment, the antifriction alloy powder is placed on the surface of the inwall first, so Laser melting coating is carried out using laser again afterwards, so that the surface of the antifriction alloy powder and the inwall is molten to congeal into one Form the laser cladding layer 3.

In the present embodiment, the thickness H of the laser cladding layer 3 value range is met：1.5≤H≤3.0mm；As excellent The embodiment of choosing, the thickness H of the laser cladding layer 3 is set to 2.5mm.Meanwhile, the target shell 1 after Laser Cladding Treatment Hardness be HRC50 between HRC70, the hardness of the target shell 1 is preferably set to HRC55.

Obviously, above-described embodiment is only intended to clearly illustrate example, and the not restriction to embodiment.It is right For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or Among changing still in the protection domain of the invention.
