Abstract
The present invention discloses a processing method for metal wires and a wire drawing machine for implementing the method. The method comprises the following steps that the drawing is carried out by fine wires which are plated with brass; the drawing with 25 tracks is carried out from the wire inlet to the wire outlet; the method can be achieved by a wire-drawing machine which is composed of a turnover box body, a transmission system, a lower box body (3), a shaft, cone pulleys, a mould frame, a wire drawing mould and a motor (2) and has six shafts and 24 cone pulleys. Thus, the compression ratio of tracks can be reduced so that the drawing stress can be reduced; thereby, the friction resistance of a steel wire and the mould wall can be reduced, the efficiency of the drawing and the quality of a single wire are improved, and the production cost is reduced.
Description
Technical field
The present invention relates to a kind of metal wire rod processing method, particularly the filament behind brass plating carries out the method for drawing, and the wire drawing machine of implementing this method.
The prospect technology
Above-mentioned traditional wire rod wire-drawing processing method is to adopt the filament of brass plating by 19 or 21 passes of drawing, it is by the drawing moulding of water tank drawbench by 4 axle two sections, because its overall compression ratio is little, the passage compression ratio is big, the toughness that causes goods is with temperature improving simultaneously, in addition because drawing stress is big, cause that on the one hand coefficient of friction increases, thereby influence die life, mold heat increases on the other hand, cause lubricant, power consumption, the loss of copper layer to increase, drawing speed is little.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can make goods have a kind of wire rod wire-drawing processing method that toughness and intensity preferably and drawing speed increase and the as above wire drawing machine of method of a kind of enforcement is provided.
For achieving the above object, a kind of metal wire rod processing method of the present invention, be to carry out drawing with the filament behind the brass plating, from the inlet wire to the outlet through 25 passes of drawing, wire drawing die drawing between 24 cone pulleys that wire rod is provided with by 6 axles gets finished product, 6 axles be arranged in parallel, and every axle is provided with 4 cone pulleys that are in series, and every diaxon is a drawing section.
A kind of metal wire rod processing method of the present invention, the speed difference is than being 8: 7 between the diaxon of each drawing section, and speed progressively increases progressively between the section of three sections, and velocity ratio is 3.325 between its section.
A kind of wire drawing machine of the present invention mainly is made up of overturning cabinet, transmission system, lower box, axle, cone pulley, mould bases, wire drawing die and motor, is provided with the axle that is parastate in the overturning cabinet, and every axle is provided with 4 cone pulleys that are series connection.
A kind of wire drawing machine of the present invention, its arrangement is suitable to be II axle, I axle, IV axle, III axle, VI axle, V axle.
The present invention adopts the filament through brass plating to utilize the cold drawn plastic deformation of steel wire by 24 cone pulleys of 25 passages, the metal steel wire is strengthened, the drawing of its 25 passage reduces Reduction per draft, and the cementite that prevents steel wire inside breaks and causes steel wire to produce fragility, has guaranteed product toughness preferably.Make overall compression ratio increase owing to passed through three drawing sections, thereby the passage compression ratio reduces drawing stress, the frictional resistance of steel wire and die wall is reduced, the flow heat reduces.In addition, increase the mould number that immerses in the emulsion, also enlarged cooling range simultaneously.Because adopt the layout of six shaft types, the heat that more helps in the drawing distributes, mould and lubricated condition of work are well improved, reduced lubricant quantity, reduced power consumption, reduced the loss of brass plating.
Because the speed difference of adjacent reel is fixed, guaranteed to equate that by the flow of each mould the established technology ratio of elongation is slightly larger than mechanical ratio of elongation, makes continuous drawing be achieved, thereby has improved drawing speed and monofilament quality, has reduced production cost.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is explained.
Fig. 1 is the front view of a kind of wire drawing machine of the present invention
Fig. 2 is the transmission diagram of a kind of water tank drawbench of the present invention
The specific embodiment
According to shown in Figure 1, main frame have two main partly, i.e. the lower box 1 of splendid attire emulsion and overturning cabinet 4 that cone pulley wire drawing die assembly, main motor 2, belt wheel, synchronous cog belt and final capstan 3 are housed.As wearing the workbench of material and crawl foot pedal 5 in front, electrical control panel is assemblied on the power distribution cabinet in main frame left side.Main motor 2 and final capstan 3 are installed in the top of overturning cabinet 4, and so as to averaging out with the cone pulley assembly, handle reverse 6 provides enough moment, make overturning cabinet 4 rotatable 90 degree.
According to shown in Figure 2, wire drawing machine is provided with parallel six roots of sensation axle, putting in order of six roots of sensation axle is II axle 11, I axle 12, IV axle 13, III axle 14, VI axle 15, V axle 16, every axle is provided with four cone pulleys that are series connection, its every group four cone pulleys are respectively A cone pulley 7, B cone pulley 8, C cone pulley 9 and D cone pulley 10.
Cone pulley is fixed by the cone pulley bearing assembly, and step pulley shaft and main motor 2 are respectively by relevant belt wheel, and synchronous cog belt carries out Synchronous Transmission.Before silk mould bases 17 and back silk mould bases 18 between two pairs of cone pulleys, each mould bases centering is independently regulated, and can keep wearing that each section steel wire and die channel drop on the same axis when expecting.
Each cone pulley is combined by the steel loop that high rigidity is taper slightly, the steel wire of traction is endwisely slipped along the cone pulley generation, avoid steel wire to concentrate the wearing and tearing cone pulley, because cone pulley rotates traction steel wire, make steel wire and be fixed on actionless mould relativity in the mould bases, thereby reach the purpose of drawn steel wire.(last the 25th wire drawing die is vertically mounted on the above adjustable whole die holder of liquid level.)
Whole drawing be finer wire with brass plating from the inlet wire to the outlet through 25 passes of drawing, realize by the wire drawing die drawing that is immersed between 24 cone pulleys on 6 axles in the emulsification lubricating fluid.Every diaxon is a drawing section, and velocity ratio is 8: 7 between the diaxon of each drawing section, and the speed between the section of three drawing sections progressively increases progressively, and its overall travel speed ratio is 3.325.
It is 19,21 and the effect comparison table of the present invention's 25 passages that drawing passes is provided below.(its cord monofilament phosphorus content 0.72%, steel wire patenting intensity 1220Mpa before wet the drawing.)
