Description

Technical Field

[0001] The invention relates to the technical field of wire drawing machines, and in particular to a continuous wire drawing machine with a wire tensioning device. Background Art

[0002] During the operation of the wire drawing machine, the wire passes through the wire drawing die of the wire drawing machine and is then wound on the wire drawing wheel. The unwinding mechanism and the reeling mechanism are in operation to provide traction for the wire. Under the action of the traction tension, the metal wire is wound through the reel and then passes through the wire drawing die where the specifications are drawn step by step, thereby continuously changing the metal wire from thick to thin. Most of the existing continuous wire drawing machines use straight-line wire drawing machines to obtain metal wires of different wire gauges.

[0003] For example, a Chinese patent with application number CN202311245517.2 discloses a straight-in wire drawing machine that can quickly wind up the wire, including an anti-coking mechanism, which is arranged on the top of the device body. The surface of the winding roller is spirally wound with steel wire, and one end of the steel wire passes through the anti-coking mechanism. The anti-coking mechanism squeezes and necks the steel wire, and then the steel wire is wound on the surface of another winding roller. The winding roller controls the steel wire to pass through the anti-coking mechanism to reduce its diameter, which solves the problem that the steel wire cannot be vertically extruded and drawn, causing the steel wire to be torn. However, in this wire drawing machine, although vertical extrusion wire drawing can be achieved, when the steel wire is continuously drawn, since the die in the anti-coking mechanism is fixed on the lubricating wall, as the lubricant is consumed, the heat at the extrusion neck cannot dissipate in time, resulting in uneven flow of the steel wire material, uneven mechanical properties of the inner and outer layers of the metal, and easy peeling on the surface of the wire; and since the wire diameter of the steel wire changes after passing through each stage of drawing, the working line speed of each drawing head should also change, and the various drawing heads cannot keep in sync. The steel wire is only pulled by the guide roller, and the wire between the drawing units cannot maintain the tension effect during the drawing process, affecting the wire drawing quality. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a continuous wire drawing machine with a wire tensioning device to solve the technical problems of poor heat dissipation at the extrusion necking point in the prior art and difficulty in maintaining the wire tensioning effect between the wire drawing units during the wire drawing process.

[0050] The wire tensioning device is used to drive the swing arm 7 to rotate, and the wire tensioning device is also used to drive the stirring member 10 to slide back and forth in the lubricant box 5.

[0051] In this embodiment, the wire drawing die assembly includes:

[0052] A mounting seat 11, the mounting seat 11 is installed in the lubricant box 5;

[0053] A split-type drawing head 12, both sides of the mounting seat 11 are provided with mounting openings 13, the split-type drawing head 12 is installed on the mounting opening 13 facing the side of the incoming wire end, and a splicing gap 14 is provided on the split-type drawing head 12;

[0054] A closing plate 15 is detachably mounted on one side of the inlet end of the lubricant box 5. The inlet port of the split-type drawing head 12 is assembled on the closing plate 15 through a shielding ring 16. The shielding ring 16 shields the splicing gap 14 on one side of the inlet end of the split-type drawing head 12. A lubricant receiving opening 17 is provided on the mounting seat 11. The splicing gap 14 is placed directly below the lubricant receiving opening 17.

[0055] A movable pulling head 18, which is slidably placed in the middle of the mounting seat 11 through a guide rail 19;

[0056] The wire drawing lead-out head 20 and the wire outlet end of the lubricant box 5 are installed with a closing plate 21 , and the wire drawing lead-out head 20 is installed on the closing plate 21 .

[0057] In this embodiment, the wire tensioning device comprises:

[0058] The cylinder 22 is mounted on the closing plate 15, and a relief opening is provided on the mounting seat 11. A slider 23 is slidably arranged in the relief opening. The movable drawing head 18 is mounted on the slider 23. The lower end of the slider 23 passes through the relief opening and is connected to the output end of the cylinder 22.

[0059] A mounting bracket 24 is provided at the lower end of the slider 23 and is placed on the other side of the connection between the output end of the cylinder 22 and the slider 23. The agitator 10 is mounted on the mounting bracket 24;

[0060] A push rod 25, one end of which is mounted on the mounting bracket 24, and the other end of which passes through the closing plate 15 and is rotatably mounted with a telescopic upper rod 26;

[0061] The telescopic lower rod 27 and the lower end of the telescopic upper rod 26 are telescopically arranged on the telescopic lower rod 27 . A slide groove 28 is provided at the upper end of the swing arm 7 , and the lower end of the telescopic lower rod 27 is slidably arranged in the slide groove 28 .

[0062] In this embodiment, the elastic part includes a base wheel 29 and a spring 30. The base wheel 29 is installed on the rotating shaft 8. There are several springs 30. One ends of the several springs 30 are evenly distributed on the outer surface of the base wheel 29, and the other ends of the several springs 30 are connected to the take-up I-shaped wheel 9.

[0063] In this embodiment, when in use, the steel wire to be drawn is spirally wound along the spiral grooves on the surface of each winding drum 4. Since the upper surface of the wire accumulation docking platform 6 is inclined, and the winding drum 4 and the lubricant box 5 are both installed on the upper surface of the wire accumulation docking platform 6, the winding drum 4 and the lubricant box 5 are also inclined, so that during the drawing and conveying process of the steel wire, the output height on the upper winding drum 4 is consistent with the entry height on the next winding drum 4, avoiding the height difference of the steel wire conveying, reducing the unbalanced force degree between the surface and the core of the steel wire, and passing through multiple wire drawing units so that the steel wire is gradually drawn into a thin diameter steel wire. In a wire drawing unit, the steel wire is placed into the split drawing head 12 through the wire inlet port of the closing plate 15, and the lubricant in the lubricant box 5 passes through the various splicing gaps 14 on the split drawing head 12, which can completely cover the surface of the wire during the continuous drawing process of the wire, so as to achieve the timely dissipation of the heat generated by the squeezed neck, so as to ensure that the mechanical properties of the inner and outer layers of the wire are more uniform, and avoid the peeling phenomenon on the surface of the wire. Under the non-comprehensive pre-drawing effect of the split drawing head 12, the drawing action does not completely thin the wire, and the wire entering the lubricant box 5 has a concave and convex cross-section;

[0064] At the same time, under the reciprocating drive of the extension and reset of the output end of the cylinder 22, the movable drawing head 18 on the slider 23 can slide reciprocatingly along the guide rail 19. During the reset return process of the output end of the cylinder 22, the movable drawing head 18 will be driven to slide toward one side of the split drawing head 12, and the raised section of the wire that has not completed the drawing action in the pre-drawing process can be further dynamically squeezed and necked to complete the overall thinning operation of the wire. In the subsequent squeezing and necking stage, the surface of the wire will be completely covered by the lubricant in the lubricant box 5, and the heat generated at the squeezing and necking place in the pre-drawing stage is lower and dissipated in time.

[0065] Moreover, during the sliding process of the movable drawing head 18 in this direction, the wire material on the front side of the first closing plate 15 in the wire feeding direction will be blocked during transportation, resulting in the slack of the wire material in this wire drawing unit. During the reset return process of the output end of the air cylinder 22, the top push rod 25 will drive the telescopic upper rod 26 to move in the wire material feeding direction, and drive the swing arm 7 to swing outward through the sliding of the lower telescopic lower rod 27 in the sliding groove 28, and drive the wire winding spool 9 at the top to swing synchronously through the rotating shaft 8, so as to solve the problem of wire material slack in this wire drawing unit, and cooperate with the elastic part in the wire winding spool 9 to ensure the tensioning effect. The movable drawing heads 18 and the split drawing heads 12 in each wire drawing unit can be kept synchronous to match the speed changes of each wire drawing unit during the wire drawing process. Moreover, the reciprocating sliding of the slider 23 will drive the stirring part 10 to move reciprocally synchronously in the lubricant box 5 through the mounting bracket 24, and then continuously stir the lubricant in the lubricant box 5 to prevent the lubricant from caking. Finally, the wire material after being drawn thinner enters the next wire drawing unit through the wire drawing outlet head 20 on the second closing plate 21 for further extrusion and necking down.

[0066] In this embodiment, as Fig. 9 shown, the side of the stirring part 10 facing the split drawing head 12 is evenly distributed with agent passing openings 31. During the process of the stirring part 10 sliding towards the first closing plate 15, the lubricant can pass through the agent passing openings 31 and enter the inner cavity of the stirring part 10, and push the lubricant in the lubricant box 5 towards the side of the splicing gap 14 on the split drawing head 12, so that during the consumption process of the lubricant in the lubricant box 5 during continuous wire drawing, the heat generated at the spreading and squeezing necking place during the pre-drawing process can be guaranteed to the greatest extent.

[0067] In this embodiment, as Fig. 9 shown, the side of the stirring part 10背离 the split drawing head 12 is a closed structure 32. During the process of the stirring part 10 sliding towards the second closing plate 21, the lubricant is blocked by the closed structure 32 at the side end to stir the lubricant in the lubricant box 5.

[0068] In this embodiment, as Figure 1 、 Figure 2 、 Fig.10 shown, there are several driving mechanisms, and several driving mechanisms respectively drive several drums 4 to rotate. The driving mechanism includes a driving motor 33 and a mounting frame 34. The mounting frame 34 is a U-shaped structure, and the two ends of the mounting frame 34 are mounted on the lower end of the machine frame 3 in a height difference manner. The driving motor 33 is mounted on the mounting frame 34, and the output end of the driving motor 33 penetrates through the machine frame 3 and the wire accumulating and docking platform 6 and is coaxially mounted with the drum 4, so that the rotation speed of each drum 4 can be independently controlled, and can be flexibly controlled according to different wire material specifications and production requirements to ensure that the wire tensions in different wire drawing units are consistent and improve the quality of the wire drawing products.

[0069] In this embodiment, if Figure 7 As shown, a vacuum cleaner 35 is installed inside the wire docking platform 6, and a dust suction pipe 36 is installed at the dust suction port of the vacuum cleaner 35. A dust collecting port is opened at the other end of the dust suction pipe 36, and the dust collecting port extends to the wire inlet end of the split pulling head 12. When the wire diameter of the wire at the wire inlet end of the split pulling head 12 changes suddenly, dust is very likely to fall on the surface of the wire, and the fallen dust will be directly placed in the dust collecting port below under the suction force and collected.

[0070] In this embodiment, if Figure 2 As shown, a visual sensor 37 is installed on the closing plate 21, and the observation range of the visual sensor 37 is toward the reel 4. The visual sensor 37 directly observes the winding situation of the wire on the reel 4 to avoid the overlap of the wire in the spiral groove on the surface of each reel 4.
