Description

A kind of vertical welding cladding combined process and equipment that is used to produce the composition metal pole stock

The present invention relates to a kind of vertical welding cladding Processes and apparatus, particularly a kind of material with two kinds of different metal materials vertically welds cladding combined process and equipment.

At present, the technical process of the manufacture of materials composition metal pole stock of two kinds of different metal materials is had certain limitation, for example production of copper Baogang pole stock generally is to adopt casting and roll process, copper pipe cover steel bar extrusion technology etc. to be made.But these processes, production efficiency is low, and is easily broken, lack of homogeneity, length is short, and conductance only is confined to 20-30%, and when especially using in the humid area, the very fast oxidation corrosion of steel pole that combines bag in bad the causing because of the copper layer with steel core causes broken string.

The object of the present invention is to provide a kind of production efficiency is higher, can produce big length composition metal pole stock continuously vertical welding cladding combined process and equipment.

The object of the present invention is achieved like this: with core material metal pole stock 1 unwrapping wire; cleaning; alignment; kalamein band 3 unwrapping wire; scratch brushing; cut edge; after the take-up of surplus limit; under the draw of draw-gear 12; the kalamein band 3 that cleans the core material metal pole stock 1 of alignment and scratch brushing side cut is brought in the inert gas shielding case 8 that make-up machine 7 is installed simultaneously; under the gas shield state after make-up machine 7 vertically clads moulding with kalamein band 3 and core material metal pole stock 1; adopt welder 9 to weld; 3 welding of kalamein band are encased core material metal pole stock 1; make the compound pole stock 14 that has welded enter compacting device 10 then; kalamein band 3 and core material metal pole stock 1 are fitted tightly; enter stage die 11 again; make kalamein band and core material metal pole stock reach metallurgical binding, enter the take-up mechanism 13 that rotates through draw-gear 12 and make finished product composition metal pole stock.Core material metal pole stock 1 and kalamein band 3 are different metal, and welder 9 adopts the argon arc welder, or laser soldering device, or the oxygen welding device.Be used for the vertically equipment of welding cladding combined process; it comprises straightener 2; metallic brush 4; bead cutter 5; admission machine 6; make-up machine 7; gas shield case 8; welder 9; stage die 11; draw-gear 12; take-up mechanism 13 rotates; compacting device 10 by motor or engine drive particularly is installed between welder 9 and stage die 11; compacting device 10 is opened the chuck 15 of circular hole by the centre; 3-6 claw 17 and contact roller 18 and adjust bolt 16 and form; one end of claw 17 is evenly packed in around the perforate of chuck 15 by direction along pole stock; the other end along pole stock by direction fluting and in groove, contact roller 18 is housed by axle sleeve; the diameter of contact roller 18 is greater than the thickness of the contact roller installation end of claw 17; or the outer rim of contact roller 18 is protruded the inwall of claw 17; adjustment bolt 16 by rotation and claw 17 thread connection moves each claw 17 simultaneously along the archimedean spiral groove on the chuck 15 19, and drive claw 17 radially moves in or out simultaneously along chuck 15.

In sum, advantage of the present invention is: adopt vertical welding cladding combined process of the present invention to enhance productivity, can continuously produce the composition metal pole stock of big length, because compactness improves, its conductance of the pole stock of producing and intensity all have raising (conductance can reach 20-40%), good uniformity, erosion resistant, are difficult for broken string.

The invention will be further described below in conjunction with drawings and Examples.
