For example, the first set of roller assemblies 21 near the side of the feeding port 101 is disposed in the transverse direction perpendicular to the wire rod, so that the roller assemblies 21 roll in the transverse direction of the wire rod; the second set of roller assemblies 21, which are adjacent to the first set of roller assemblies 21, are disposed in a direction perpendicular to the longitudinal direction of the wire material so that the second set of roller assemblies 21 roll in the longitudinal direction of the wire material. By providing two sets of roller assemblies 21 as described above, the wire rod can be rolled in the transverse and longitudinal directions thereof in sequence. When the roller set 20 includes a plurality of roller assemblies 21, the roller assemblies 21 may be sequentially arranged in the transverse and longitudinal directions perpendicular to the wire material to perform the rolling of the wire material in all directions. When the wire passes through each roller assembly 21, the wire can be uniformly pressed around the periphery thereof to improve the drawing effect of the wire.

Referring to fig. 2 to 4, in one embodiment, the roller assembly 21 includes a roller bracket 22 and two rollers 24 mounted on the roller bracket 22 in parallel by a roller shaft 23. The wire passes through the roller assemblies 21 in sequence as it passes through the drawing chamber 11 of the die box 10, and the wire passes through two rollers 24 of the roller assemblies 21 to drag the two rollers 24 to rotate around the corresponding roller shafts 23, so that the rollers 24 roll while the wire is drawn to extrude the wire.

Referring to fig. 1 to 5, in one embodiment, the rollers 24 have drawing grooves 241, and the drawing grooves 241 of the rollers 24 surround to form a drawing area 242 for drawing the wire. By utilizing the drawing groove 241 on the roller 24, the drawing grooves 241 of the two rollers 24 arranged in parallel together enclose to form a drawing area 242, when a wire is drawn, the wire moves in the drawing area 242, and the wire and the drawing groove 241 support have friction force to drag the rollers 24 on two sides to rotate, so that the rollers 24 rotate simultaneously to roll the wire during wire drawing.

Referring to fig. 1 to 5, in one embodiment, the drawing area 242 of each roller assembly 21 is gradually reduced along the drawing direction of the wire. The drawing areas 242 of the roller assemblies 21 are set to be different in size, namely the drawing area 242 of the first group of roller assemblies 21 close to the feeding port 101 is larger than the drawing area 242 of the second group of roller assemblies 21 close to the first group of roller assemblies 21, and so on, the drawing area 242 of the front group of roller assemblies 21 is larger than the drawing area 242 of the rear group of roller assemblies 21, when the wire is drawn, the wire sequentially passes through the roller assemblies 21 at all levels, namely, the drawing areas 242 through which the wire passes are continuously reduced, the force borne by the wire is gradually increased, and therefore, the rolling force borne by the wire is gradually increased in the wire drawing process, the drawing effect of the wire is effectively improved, and the wire forming is easy to realize.

Referring to fig. 1 to 5, in an embodiment, the roller frame 22 includes a bottom frame 221 and side frames 222 disposed on the same side of the bottom frame 221 and spaced apart from each other, opposite ends of the roller shaft 23 are mounted on the side frames 222, and the bottom frame 221 is provided with a through hole 223 engaged with the material inlet 101. Opposite ends of the roller shaft 23 are mounted on the side brackets 222 at both sides to mount the rollers 24 on the bottom frame 221, and the bottom frame 221 is provided with through holes 223 through which the wire can enter the drawing area 242 between the two rollers 24. The bottom frame 221 may be a planar plate-shaped bracket, and when the roller assembly 21 is installed, the bottom frame 221 is inserted against the inner wall of the drawing chamber 11 on the side close to the material inlet 101, so that the through hole 223 of the bottom frame 221 is aligned with the material inlet 101. When the number of the roller assemblies 21 is two, the chassis 221 of the other roller assembly 21 is inserted against the inner wall of the drawing chamber 11 on the side away from the material inlet 101, so that the through holes 223 of the chassis 221 are aligned with the holes into the lubrication chamber 12, and the roller shafts 23 of the two roller assemblies 21 are arranged in a cross shape with respect to each other and the drawing areas 242 of the two roller assemblies 21 are arranged opposite to each other. When the wire rod enters the die box 10, the wire rod firstly enters the drawing chamber 11 through the feeding port 101, passes through the perforation 223 of the bottom frame 221 of the first roller assembly 21, penetrates into the drawing area 242 of the second roller assembly 21 through the drawing area 242, enters the lubricating chamber 12 and the die chamber 13 through the perforation 223 of the bottom frame 221, and is removed from the die box 10 through the discharging port 102 to finish the drawing work.

Referring to fig. 1 to 3, in one embodiment, a blow-off hole 111 is formed in the drawing chamber 11 of the die box 10. During the wire drawing process, a large amount of dust and oil stains exist. Through opening the blowoff hole 111 in drawing room 11, when rolling and mould drawing device 100 carry out drawing work, because there are dust and greasy dirt on the wire rod, running roller 24 can extrude foul such as greasy dirt at the in-process of extrusion wire rod, can be with foul discharge drawing room 11 through blowoff hole 111, avoid the foul to pile up, running roller 24 receives the influence of foul and influences the wire rod effect of drawing at the in-process that the roll rolled the wire rod.

Referring to fig. 1 to 5, in one embodiment, the side bracket 222 is provided with an avoiding groove 224 for discharging dirt. By providing the escape groove 224 in the side bracket 222, when the rolling and die drawing apparatus 100 performs the drawing operation, dirt such as oil stain extruded when the wire is pressed by the roller 24 can flow out of the inside of the roller assembly 21 through the escape groove 224, and the influence of the dirt accumulation on the drawing operation can be prevented. Because the bottom frame 221 is a planar plate-shaped structural support, after the side frames 222 are installed on the two opposite sides of the bottom frame 221, the side frames 222 and the side walls of the drawing chamber 11 form a closed structure, and dirt can flow out of the closed structure by forming the avoiding groove 224 on the side frame 222 and be discharged through the sewage discharge hole 111 of the drawing chamber 11 to avoid dirt accumulation to influence the wire drawing effect. Specifically, the escape groove 224 of the side bracket 222 may be opened at a side close to the bottom frame 221, and when the side bracket 222 is mounted on the bottom frame 221, the escape groove 224 prevents the side bracket 222 from being folded and closed with the bottom frame 221. The side bracket 222 may be chamfered to form the avoiding groove 224, or the side bracket 222 may be perforated, which may be selected according to the actual situation.

Referring to fig. 1 to 5, in one embodiment, the material inlet 101 is in a bell-mouth structure with a small opening facing the drawing chamber 11. Wherein, the small opening refers to the end with smaller caliber of the bell mouth. Set pan feeding mouth 101 to the horn mouth structure, when the wire rod wire drawing, the wire rod will at first get into die box 10 through the pan feeding mouth 101 of horn mouth structure when getting into die box 10, and the wire rod is squeezed when pulling out from its osculum through the structure of horn mouth when passing through pan feeding mouth 101 and is tightened up, then rolls through each roller subassembly 21 again and draw, and the effectual effect of drawing that has improved.

Referring to fig. 1 to 5, in an embodiment, a drawing die 30 for drawing the wire is installed in the die chamber 13, the drawing die 30 is opened with a drawing passage 31 for the wire to pass through, and a diameter of the drawing passage 31 gradually decreases along a drawing direction of the wire.
