1. It is 1. a kind of for manufacturing the superelevation rate laser cladding method of hydraulic support column, which is characterized in that the step of this methodIncluding:



  • 1)

    To powder of stainless steel screening and purified treatment, after obtaining satisfactory powder, the then vacuum after drying and processingIt seals up for safekeeping, it is spare;



    2)

    The technological parameter of superelevation rate laser melting coating is set, concrete technology is:

    Spot diameter be 1~3mm, leg surface lineSpeed, that is, cladding rate be 20~75m/min, 0.2~0.4mm of feed of every rotation, laser power be 1100~1600KW, powder feedingRate is 5~25g/min;



    3)

    By the column matrix clamping of any surface finish zero defect, diameter less than 0.2~0.6mm of finished diameter in numerical control deviceOn swing mechanism, and adjust hot spot(

    Laser spot)

    And amyloid plaque(

    Powder of stainless steel convergent point)

    Relative to column matrix clad can fusionPosition;



    4)

    Using coaxial powder-feeding ultrahigh speed laser cladding method, step is used(

    2)

    The technique is by step(

    1)

    Gained is notPowdered steel cladding become rusty to column matrix surface, obtains the coating that thickness is 0.10~0.45mm;

    Column diameter is more than finished product at this time0.1~0.3mm of diameter;



    5)

    Keep column linear velocity, feed of every rotation and focal position of laser constant, laser power is reduced to 800~1500KW carries out laser remolten under the conditions of powder of not bothering to see me out to cladding coating, obtains smooth surface light, the painting without pit and crackleLayer.
