Abstract
A wet drawing method for manufacturing the aluminium clad steel wire used for electric engineering is characterized by that the semi-finished aluminium clad steel wire is drawn through multi-pass drawing die by drawing machine while the lubricating oil is applied.
Description
Technical field
What electrician of the present invention related to the wet daraf(reciprocal of farad) of aluminum cald steel wire is a kind of method of utilizing lubricating oil to come the drawing aluminum cald steel wire as lubricant medium, and the aluminum cald steel wire of this method drawing is widely used in bridge, railway, electric power.Can make special-shaped aluminium-clad steel wire material according to demand.
Background technology
Aluminum current Baogang product generally is used in electric power, bridge, railway.Concerned power has: lead, aluminium Baogang core aluminum stranded wire, aluminum-cladding stranded wire; Bridge railway aspect has: have high-intensity anti-oxidation carrying suspension cable etc.The drawing mode of existing employed aluminum cald steel wire is for making the drawing mode of lubricant medium of powdered lubricant.This product when producing because powdered lubricant enters the amount of wire drawing die can not remain the same from beginning to end, thereby make the external diameter of this product constantly produce fluctuation, the stress that product bore is seriously uneven, in the next procedure production process, exist certain hidden danger, it is easy fracture of wire, simultaneously product glossiness is poor, and the next procedure that circulates of attaching surface such as dust foreign material is arranged.Because particularly the cost cost of OPGW is than high for power cable, the next procedure of being everlasting during this hidden danger causes production accident, causes very high economic loss to enterprise, from several ten thousand to hundreds of thousands.
Summary of the invention
The purpose of utility model of the present invention is at above-mentioned weak point, a kind of electrician is provided the wet daraf(reciprocal of farad) with aluminum cald steel wire, promptly utilize a kind of Hubbing method of lubricating oil as lubricant medium, with original powder contact becoming oil contact, because the oil film that lubricating oil forms is very uniform, therefore solved the defective that powdered lubricant is caused owing to the charging inequality in greasing under pressure constant state.The product surface that goes out with wet daraf(reciprocal of farad) drawing is mellow and full, fine and smooth, smooth, bright, no-sundries is detained; Because the external diameter of product is consistent evenly in drawing process, same product each several part stressed also very evenly, therefore improved the quality of product greatly, reduced wire broken rate, improved economic benefit of enterprises.
The electrician takes following scheme to realize that its method is as follows with the wet daraf(reciprocal of farad) of aluminum cald steel wire:
1, semi-finished product aluminum cald steel wire (coating good aluminum cald steel wire on the coating assembly line) is placed on the pay off rack;
2, the semi-finished product aluminum cald steel wire is carried out drawing by wire drawing machine and multiple tracks wire drawing die, in the wire drawing die cavity, charge into constant voltage lubricating oil continuously during drawing, make to remain balanced oil film between aluminum cald steel wire and wire drawing die but not directly contact; Wire-drawing die and wire drawing oil all must cool off in process of production;
3, carry out the take-up of finished product aluminum cald steel wire through admission machine.
The advantage of the wet daraf(reciprocal of farad) of aluminum cald steel wire:
1, mellow and full, fine and smooth, smooth, bright, the no-sundries of the product surface that goes out of drawing is detained, and can not influence the production of next procedure because of being detained foreign material.
2, the product external diameter high conformity that draws out, the stress unanimity that each several part bore in drawing process has improved rate of finished products, has reduced wire broken rate, for the production of next procedure provides safety guarantee.
Embodiment:
The electrician is as follows with the wet daraf(reciprocal of farad) technological process of aluminum cald steel wire:
1, on coating assembly line, produces the semi-finished product of aluminum cald steel wire according to different conductances; (coating good aluminum cald steel wire on the coating assembly line) places on the pay off rack of wire-drawing production line with the semi-finished product aluminum cald steel wire;
2, the semi-finished product aluminum cald steel wire is carried out the drawing in 6-12 road by wire drawing machine and wire drawing die, in the wire drawing die cavity, charge into constant voltage lubricating oil continuously during drawing, make to remain balanced oil film between aluminum cald steel wire and wire drawing die but not directly contact; Wire-drawing die and wire drawing oil all must carry out cooling processing with cooling water in process of production;
3, carry out the take-up of finished product aluminum cald steel wire through admission machine.
Claims (1)
1, a kind of electrician is characterized in that with the wet daraf(reciprocal of farad) of aluminum cald steel wire:
(1) will place on the pay off rack at the semi-finished product aluminum cald steel wire that coating is good on the coating assembly line;
(2) the semi-finished product aluminum cald steel wire is carried out drawing by wire drawing machine and multiple tracks wire drawing die, in the wire drawing die cavity, charge into lubricating oil continuously during drawing, make to remain balanced oil film between aluminum cald steel wire and wire drawing die but not directly contact; Wire-drawing die and wire drawing oil all must cool off in process of production;
(3) carry out the take-up of finished product aluminum cald steel wire through admission machine.
