Description

Technical Field

[0001] The invention belongs to the technical field of continuous casting and rolling of nonferrous metals, and particularly relates to a multi-model copper rod production line. Background Art

[0002] A continuous casting and rolling production line for copper rod typically includes a melting furnace, a continuous casting machine, a bridge approach, a haul-off machine, a shear, a roughing machine, a continuous rolling mill, a cooling system, a horizontal haul-off mechanism, a swing arm, and a rod-collecting trolley, all arranged in sequence along the strand conveying direction L. Solid copper metal is melted into liquid in the melting furnace. The liquid copper is then transported via chutes or pipes to the continuous casting machine for strand casting. The strands are then transported via the bridge approach to the haul-off machine. From the haul-off machine, the strands are fed to the shear, where they are sheared to remove any poorly crystallized front ends. The strands then enter the roughing machine for roughening. The roughened strands then enter the continuous rolling mill, where they are rolled into copper rod that meets the requirements. From the continuous rolling mill, the copper rods are fed to the cooling system for cooling and reduction. After exiting the cooling system, the copper rods enter the horizontal haul-off mechanism, which transports them to the swing arm, where they are swung into a coil. When the copper rod is wound to the appropriate number of turns, it is cut and the coiled copper rod falls into the rod collection trolley. The above production line is suitable for the production of thin copper rods, which usually have a diameter of 8 to 10 mm.

[0003] During the actual production process, the internal through-hole diameters of the cooling system, the horizontal traction mechanism, and the swing arm machine are all adapted to the diameter of the copper rods being produced to prevent the copper rods from deviating from the conveying path or causing blockage during the copper rod conveying process.

[0004] The existing continuous casting and rolling production line for copper rods has the following technical problems:

[0005] 1. Due to the limitation of the wire-winding principle, the swing-arm machine bears too much load when winding thick copper rods with larger diameters, making it difficult to wind the thick copper rods into a coil. This results in a poor winding effect on thick copper rods. The diameter of thick copper rods is usually 12.5 to 50 mm.

[0006] 2. Since the continuous rolling mill can adjust the copper rod diameter, if the diameter of the copper rod coming out of the continuous rolling mill does not match the current swing rod machine, it is impossible to take up copper rods of different diameters. Only copper rods of a single diameter can be taken up, which has the disadvantage of a small scope of application. Summary of the Invention

[0034] Compared with the existing technology, the present invention has the following advantages: it provides a multi-model copper rod production line that can realize the production and winding of both thick copper rods and thin copper rods. It also has the following advantages:

[0035] 1. During continuous production, when the thick copper rod is cut, it is easier for the head of the subsequent thick copper rod to be wound into the bending deformation channel, and it is easier for the previous roll of thick copper rod to fall into the rod-taking trolley. The basket change operation does not affect continuous production, ensuring the winding of the thick copper rod during continuous production of the production line.

[0036] 2. By setting the first mounting tube and the second mounting tube, the rod passage formed by the first mounting tube and the second mounting tube is open and closeable. When the thick copper rod is continuously cut into sections, the waste can be directly dropped from the opening of the rod passage for collection, thereby preventing the waste from entering the conveying pipeline and causing blockage.

[0037] 3. The roller shear is close to the take-up trolley. Compared with the original structure, the ingot is sheared in front of the continuous rolling mill. The amount of waste is greatly reduced during the basket change operation, which reduces production costs and increases the output of finished products.

[0038] 4. The original structure needs to go through subsequent rolling mills, cooling systems and other processes after the basket changing operation. The operation is complicated and labor-intensive. The operation of re-entering the rolling mill and entering the cooling system after the basket changing operation is reduced, reducing the labor intensity of workers.

[0039] 5. After the basket changing operation is completed, the rod-passing channel is closed and no manual traction is required. The subsequent thick copper rods will automatically enter the rear traction under the guidance of the rod-passing channel to continue the wire-collecting operation, eliminating manual operation and preventing workers from approaching the operating parts and the transported thick copper rods, thereby preventing safety accidents.

The continuous casting and rolling section L a With thin copper rod bent into shape segment L bconnected to form a thin copper rod production line, or the continuous casting and rolling section L a With the thick copper rod bent into the forming section L c They are connected to form a thick copper rod production line.

[0076] The continuous casting machine 301 casts and solidifies the molten metal flowing into the casting machine.

[0077] The approach bridge 302 guides the cast strand output from below the crystallization wheel of the continuous casting machine 301 to the first traction machine 303.

[0078] The traction machine 303 pulls the ingot to move to the next process.

[0079] The shearing machine 304 shears off the poorly crystallized portion at the front end of the ingot.

[0080] The roughening machine 305 roughens the surface of the ingot to facilitate the rolling of the ingot by the subsequent continuous rolling mill group 306.

[0081] The continuous rolling mill group 306 rolls the ingots to the required diameter and shape.

[0082] The thin copper rod cooling system 307 cools and reduces the rolled thin copper rod to lower its temperature.

[0083] The thin copper rod horizontal traction mechanism 308 tractions the thin copper rod output from the thin copper rod cooling system 307 and conveys the thin copper rod to the swing rod machine 309 .

[0084] The swing rod machine 309 rotates through the internal passage of the swing rod machine 309 and the swing rod tube of the swing rod machine 309, so that the thin copper rod is bent into a circle for output.

[0085] The thin copper rod receiving trolley 311 receives the coiled thin copper rod output from the swing rod machine 309, and the wire take-up basket of the thin copper rod receiving trolley 311 rotates to continuously coil the output thin copper rod into a circle.

[0086] The rough copper rod cooling system 312 cools and reduces the rough copper rod after rolling to lower its temperature.

[0087] The copper rod pre-bending mechanism 223 bends the thick copper rod output from the thick copper rod horizontal traction mechanism 313 into a loop and outputs it.

[0088] The thick copper rod receiving trolley 314 receives the coiled thick copper rod output from the copper rod material pre-bending mechanism 223. The wire collection basket of the thick copper rod receiving trolley 314 rotates to continuously coil the output thick copper rod into a coil.

[0089] Thick copper rod bending forming section L b With thin copper rod bent into shape segment L cIt can be switched and work at different times to realize the production and winding of copper rods with two different diameters. a With thin copper rod bent into shape segment L b When connected together, a thin copper rod production line is formed. a With the thick copper rod bent into the forming section L c When connected together, a thick copper rod production line is formed.

[0090] Since the thin copper rods are continuously discharged, in order to facilitate the basket changing operation, it is preferred that a thin copper rod storage frame 310 is provided on the wire taking-up stand. The thin copper rod storage frame 310 is located between the discharge port of the swing rod machine 309 and the thin copper rod taking-up trolley 311. The wire taking-up stand provides installation support for the thin copper rod storage frame 310. The bottom of the thin copper rod storage frame 310 is provided with an openable and closable baffle. When changing the basket, the baffle is closed, and the thin copper rods continuously output subsequently fall on the baffle. Then, the tail of the copper rods in the lower circle is cut off, and another wire taking-up basket is replaced. Then, the baffle is opened again, the thin copper rods fall down, and the wire taking-up continues.

[0091] like Figure 3 、 4 , 5, specifically, the copper rod pre-bending mechanism 223 includes a frame 200, a first mounting seat 202, a second mounting seat 206, a first roller mechanism and a second roller mechanism; the first mounting seat 202 is rotatably connected to the frame 200 via a first rotating seat 211, and a driving device 212 for driving the first mounting seat 202 to swing is installed on the frame 200; the first roller mechanism includes a first guide wheel 203 and an outer pressure wheel, and the first guide wheel 203 and the outer pressure wheel are both installed on the first mounting seat 202; the second mounting seat 206 is fixedly installed on the frame 200, and is located on the same side of the frame 200 as the first mounting seat 202; the second roller mechanism includes a first guide wheel 203 and an outer pressure wheel, and the first guide wheel 203 and the outer pressure wheel are both installed on the first mounting seat 202; the second mounting seat 206 is fixedly installed on the frame 200, and is located on the same side of the frame 200 as the first mounting seat 202; the second roller mechanism includes a first guide wheel 203 and an outer pressure wheel, and the first guide wheel 203 and the outer pressure wheel are both installed on the first mounting seat 202 It includes a second guide wheel 207 and an inner pressure wheel 208, both of which are mounted on the second mounting seat 206; the first guide wheel 203 and the second guide wheel 207 are arranged in pairs and form a pinching wheel group used in conjunction with each other; a rod feed port 201 is provided on the frame 200, and a curved deformation channel is formed between the first roller mechanism and the second roller mechanism, and the feed end of the curved deformation channel is arranged corresponding to the rod feed port 201; the outer pressure wheel is located on the outer curved side of the curved deformation channel, and the inner pressure wheel 208 is located on the inner curved side of the curved deformation channel, and the outer pressure wheel and the inner pressure wheel 208 are staggered along the direction from the feed end to the discharge end of the curved deformation channel.

[0092] The frame 200 provides mounting support for the drive device 212, the first mounting seat 202, and the second mounting seat 206. The first mounting seat 202 provides rotational mounting support for the first guide wheel 203 and the outer pressure wheel, and the second mounting seat 206 provides rotational mounting support for the second guide wheel 207 and the inner pressure wheel 208. Preferably, the first mounting seat 202 and the second mounting seat 206 are both arranged horizontally. The thick copper rod enters the bending deformation channel through the rod inlet 201. The first guide wheel 203 and the second guide wheel 207 arranged in pairs serve to clamp and feed the thick copper rod. The outer pressure wheel acts on one side of the thick copper rod axially, and the inner pressure wheel 208 acts on the other side of the thick copper rod axially. Through the cooperation of the outer pressure wheel and the inner pressure wheel 208, the thick copper rod is bent and continuously coiled. After the thick copper rod is wound to the appropriate number of turns, it needs to be cut off and the basket is changed to facilitate the collection of the next roll of thick copper rod. After the thick copper rod is cut, the thick copper rod on the continuous casting and rolling production line continues to be discharged, while the tail of the previous roll of thick copper rod is still clamped by the first roller mechanism and the second roller mechanism. The first mounting seat 202 is driven by the driving device 212 to swing around the first rotating seat 211, and the first mounting seat 202 and the second mounting seat 206 are opened in a direction away from the rod inlet 201, so that the previous roll of thick copper rod can fall into the rod collection trolley and the head of the subsequent thick copper rod to be rolled can smoothly enter the bending deformation channel. When the head of the subsequent thick copper rod to be rolled is fed between the first guide wheel 203 and the second guide wheel 207, the driving device 212 drives the first mounting seat 202 to swing around the first rotating seat 211, and the first mounting seat 202 approaches the second mounting seat 206, and the subsequent thick copper rod is clamped by the first guide wheel 203 and the second guide wheel 207. The subsequent thick copper rod to be wound is continuously transported along the bending deformation channel, and is bent and continuously coiled under the cooperation of the outer pressure wheel and the inner pressure wheel 208.

[0093] The drive device 212 can be a hydraulic cylinder, a pneumatic cylinder, or the like, preferably a pneumatic cylinder, which is driven by extending or shortening its piston rod. If the drive device 212 is a pneumatic cylinder, one end of the cylinder is connected to the frame 200 via a second rotating base 213, and the other end of the cylinder is connected to the first mounting base 202 via a third rotating base 214. The first rotating base 211, the second rotating base 213, and the third rotating base 214 are all hinged.

[0094] The first mounting base 202 is driven to swing by the driving device 212, thereby adjusting the width of the bending deformation channel. The control accuracy is low, which easily causes the width of the bending deformation channel to be smaller than the diameter of the thick copper rod. Figure 6As shown, the driving device 212 drives the first mounting seat 202 to swing in the direction F close to the second mounting seat 206. The thick copper rod located in the bending deformation channel has its main force-bearing points at its contact surface with the first guide wheel 203 and the second guide wheel 207. The thick copper rod located in the bending deformation channel is prone to deformation along its own radial direction, thereby affecting the quality of the rod material. Preferably, a pre-positioning structure is also included, the pre-positioning structure comprising a mounting plate 220, a bolt 221, and a positioning plate 222; the mounting plate 220 is connected to the second mounting seat 206 and is located below the second mounting seat 206; the positioning plate 222 is connected to the first mounting seat 202 and is located below the first mounting seat 202; the mounting plate 220 and the positioning plate 222 are respectively located on both sides of the bending deformation channel and are arranged correspondingly; the bolt 221 is installed on the mounting plate 220 and is in abutment with the positioning plate 222. The mounting plate 220 is welded to the second mounting seat 206, and the positioning plate 222 is welded to the first mounting seat 202. Threaded holes for the bolts 221 can be provided on the mounting plate 220, and nuts for the bolts 221 can be welded to the mounting plate 220. By adjusting the relative position of the bolts 221 and the mounting plate 220, and adjusting the distance between the mounting plate 220 and the positioning plate 222, the width of the bending deformation channel can be pre-defined to accommodate the winding of thick copper rods of different diameters. Figure 7 As shown, the driving device 212 drives the first mounting seat 202 to swing around the first rotating seat 211 in the direction F close to the second mounting seat 206. When the bolt 221 abuts against the positioning plate 222, the driving device 212 stops driving, and the mounting plate 220, the bolt 221 and the positioning plate 222 are the main force-bearing objects, preventing the thick copper rod located in the bending deformation channel from deforming along its own radial direction.

[0095] Preferably, the driving device 212 is located on the side opposite to the first mounting seat 202 and the second mounting seat 206 to avoid interference with the output of the thick copper rod.

[0096] There are various embodiments for the arrangement of the pinch wheel group, the outer pressure wheel and the inner pressure wheel 208:

[0097] In the first embodiment, the pinch wheel assembly includes a first pinch wheel assembly 218 disposed adjacent to the rod inlet 201; the outer pressure wheel assembly includes a first outer pressure wheel 204, which is located on a side of the first guide wheel 203 away from the rod inlet 201; and the inner pressure wheel 208 is located on a side of the second guide wheel 207 of the first pinch wheel assembly 218 away from the rod inlet 201 and cooperates with the first outer pressure wheel 204. The first pinch wheel assembly 218 clamps and conveys the rough copper rod, and then bends the rough copper rod through the cooperation of the first outer pressure wheel 204 and the inner pressure wheel 208.

[0098] In the second embodiment, the pinch wheel group further includes a second pinch wheel group 219. The first pinch wheel group 218 and the second pinch wheel group 219 are arranged in sequence in a direction away from the rod inlet 201. The inner pressure wheel 208 is located between the second guide wheel 207 of the first pinch wheel group 218 and the second guide wheel 207 of the second pinch wheel group 219. The first outer pressure wheel 204 is located between the first guide wheel 203 of the first pinch wheel group 218 and the first guide wheel 203 of the second pinch wheel group 219. The outer pressure wheel further includes a second outer pressure wheel 205, which is located on the side of the first guide wheel 203 of the second pinch wheel group 219 away from the first outer pressure wheel 204. The second pinch wheel group 219 further clamps and conveys the thick copper rod, and the second outer pressure wheel 205 further bends the thick copper rod and continuously coils it.

[0099] The axial directions of the first guide wheel 203, the first outer pressure wheel 204, the second outer pressure wheel 205, the second guide wheel 207 and the inner pressure wheel 208 are parallel to each other. The outer circumferences of the first guide wheel 203 and the second guide wheel 207 are curved surfaces that are concave along their own radial directions.

[0100] In order to adjust the coil diameter of the thick copper rod, it is preferred that it also includes a first roller seat 209, the second outer pressure wheel 205 is rotatably mounted on the first roller seat 209, the first roller seat 209 is slidably mounted on the first mounting seat 202, and is locked with the first mounting seat 202 by a first locking member; the first roller seat 209 slides in a direction approaching or away from the second mounting seat 206; it also includes a second roller seat 210, the inner pressure wheel 208 is rotatably mounted on the second roller seat 210, the second roller seat 210 is slidably mounted on the second mounting seat 206, and is locked with the second mounting seat 206 by a second locking member; the second roller seat 210 slides in a direction approaching or away from the first mounting seat 202. The first roller seat 209 provides a rotational mounting support for the second outer pressure wheel 205. The first roller seat 209 and the first mounting seat 202 are slidably matched by a first slider slot structure. When the first roller seat 209 is adjusted to a suitable position, the first mounting seat 202 and the first roller seat 209 are locked by a first locking member. The first locking member can be a bolt or a latch. The second roller seat 210 provides a rotational mounting support for the inner pressure wheel 208.

[0101] In the actual production process, when the thick copper rod is output from the second pinching wheel group 219, it tends to tilt upward, which is not conducive to the continuous coiling of the thick copper rod downward. In order to solve the above technical problems, it is preferred that a horizontally arranged pressing roller 215 is further included, and the pressing roller 215 is rotatably connected to the first mounting seat 202 through a roller seat 216; the pressing roller 215 is located below the discharge end of the bending deformation channel. The first mounting seat 202 provides mounting support for the pressing roller 215. After the front end of the thick copper rod is discharged from the second pinching wheel group 219, it is conveyed to the bottom of the pressing roller 215. The pressing roller 215 presses the continuously conveyed bent thick copper rod, which is conducive to the continuous coiling of the thick copper rod downward, and then falling into the rod collecting trolley. The pressing roller 215 and the bent thick copper rod are in rolling cooperation, and the friction is small.

[0102] Preferably, the axial directions of the first guide wheel 203 , the first outer pressure wheel 204 , the second outer pressure wheel 205 , the second guide wheel 207 and the inner pressure wheel 208 are all perpendicular to the axial direction of the pressing roller 215 .

The rear traction 3133 pulls the rough copper rod into the copper rod pre-bending mechanism 223, and is bent into a coil by the copper rod pre-bending mechanism 223. Finally, it falls into the rough copper rod collecting trolley 314 below. The wire collection basket of the rough copper rod collecting trolley 314 rotates to continuously coil the output rough copper rod into a coil. After reaching a suitable weight, the rough copper rod is cut by the roller shear 3132, completing the production of a roll of rough copper rod. During the basket changing operation, after the roller shear 3132 shears the thick copper rod, while the front traction 3131 continuously conveys the thick copper rod, the open and close wire passing tube 154 is opened with its opening direction facing downward. The roller shear 3132 continuously shears the conveyed thick copper rod into segments and then drops them from the open and close wire passing tube 154 for collection.
