Embodiment approach

[0106]In addition to the above first embodiment, the present invention also provides a second embodiment, the difference between the second embodiment and the first embodiment is that the n-1th laser cladding tape 5, the nth laser cladding The extension direction of the cladding strip 4 and the n+1th laser cladding strip 6 is not perpendicular to the axial direction of the hydraulic support column, but spirals around the outer surface of the hydraulic support column.

[0107] third implementation

[0108] In addition to the above first embodiment, the present invention also provides a third embodiment. The difference between the third embodiment and the first embodiment is that the alloy powder used for laser cladding contains 0.08% C, 0.9 % Si, 0.6% Mn, 18.5% Cr, 23% Ni, the balance Fe and unavoidable impurities. In this embodiment, since it contains more Ni, the cost is higher, and the Rockwell hardness is only above 30. Therefore, the effect of the third embodiment is not...

Abstract

The invention provides a method of forming a laser cladding layer on the surface of an upright post of a hydraulic bracket. The method comprises the following steps of: step a). smelting a part of widths of (n-1)th laser cladding belt and laser cladding alloy powder used for forming the nth laser cladding belt through a laser beam to form the nth laser cladding belt, wherein n is an integer larger than or equal to 2; and step b). smelting a part of widths of the nth laser cladding belt and the laser cladding alloy powder used for forming (n+1)th laser cladding belt through the laser beam to form the (n+1)th laser cladding belt. The method provided by the invention can not only efficiently perform cladding, but also obtain a cladding surface with high strength.

Description

technical field [0001] The invention relates to a method for forming a laser cladding layer on the surface of a column of a hydraulic support, belonging to the field of laser processing and manufacturing. Background technique [0002] The hydraulic support column is a key component of mining equipment. In China, the hydraulic support column is usually treated with chrome plating to prevent surface rust and corrosion. However, the wear resistance of the chrome plating layer is poor. Generally, after 1 to 1.5 years, the chrome plating layer will appear peeling and peeling. Therefore, the emulsion will corrode the surface of the column, which will affect the use effect of the hydraulic support. [0003] The Chinese patent with the notification number CN101875128B discloses a laser cladding method for mining hydraulic support columns, which uses specific laser cladding process conditions to clap three layers of metallurgical materials, thereby solving the problem of the surface ...
