Description

Technical Field

[0001] The present invention relates to the technical field of copper rod processing, and particularly to a copper rod clamping and conveying mechanism and a continuous casting and rolling production line. Background Art

[0002] Copper rods are the core raw materials in fields such as wire and cable, enameled wire, and electrical equipment. Their production quality directly affects the performance and reliability of downstream products. With the acceleration of the global electrification process and the rapid development of emerging industries such as new energy and 5G communication, the market demand for high-quality copper rods continues to grow. As the mainstream process for copper rod production, the continuous casting and rolling production line for copper rods has advantages such as high efficiency, continuity, and energy conservation. However, higher technical requirements are put forward for the clamping and conveying of copper rods during its production process.

[0003] During the continuous casting and rolling production process of copper rods, the copper rods produced by the continuous casting machine need to be moved into the rolling mill with the help of a clamping and conveying mechanism. Traditional clamping and conveying mechanisms generally use structures such as steel belts and conveyor chains distributed on the upper and lower sides or front and back sides of the copper rod to squeeze the copper rod and drive it through structures such as steel belts and conveyor chains to achieve the clamping and conveying of the copper rod. However, this clamping method can only achieve a local contact effect with the copper rod. Since the shape of the copper rod is generally cylindrical, the clamping effect of the above-mentioned clamping and conveying method is not good, and it is easy to slip; in some equipment, the method of using conveying wheels or conveying rollers is also used to clamp and convey the copper rod, and it also has the above problems. Moreover, during the rolling process, since the copper rod cannot be continuously introduced into the rolling mill at a constant speed, the conveying speed of the copper rod fluctuates. This fluctuation is directly related to the rolling interval of the rolling mill and the instantaneous speed of the copper rod output by the continuous casting machine. Traditional clamping and conveying mechanisms cannot effectively buffer this fluctuation, resulting in phenomena such as local stretching and deformation of the copper rod during continuous casting and rolling, which affects the processing quality of the copper rod. Summary of the Invention

[0004] The present invention provides a copper rod clamping and conveying mechanism and a continuous casting and rolling production line, which can effectively solve the problems in the background art.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is: A copper rod clamping and conveying mechanism includes a plurality of pinch roll units arranged along the copper rod conveying direction, and the pinch roll units are used for conveying the copper rod; Each pinch roll unit includes a wire coil, the wire coil is composed of side pulling parts located on both sides and a winding part located in the middle, and the wire coil is wound around the copper rod through the winding part. The two side pulling parts are used to tighten the winding part. When the two side pulling parts rotate self - sufficiently, the winding part turns and rolls to squeeze and convey the copper rod.

[0006] In some embodiments of the present invention, the positions of the two side pulling parts are staggered.

[0007] In some embodiments of the present invention, the distance between the two side pulling parts can be adjusted.

[0008] In some embodiments of the present invention, the position of the winding part on the winding wire can be adjusted.

[0009] In some embodiments of the present invention, the number of winding wires in the clamping and feeding unit is at least two, and the winding directions of the winding parts on each winding wire are opposite.

[0010] In some embodiments of the present invention, the clamping and feeding unit further includes an outer frame and a first rotating column corresponding to each winding wire. The first rotating column is rotatably arranged in the outer frame. Two moving sleeves are relatively slidably arranged on the first rotating column, and the first rotating column and the moving sleeves rotate synchronously. A first gear is arranged on each moving sleeve, and second gears are arranged at both ends of the winding wire. The second gears are meshed and connected with the first gears; Wherein, the moving sleeve and the second gear are connected by a connecting plate.

[0011] In some embodiments of the present invention, the clamping and feeding unit further includes a second rotating column corresponding to each winding wire. The second rotating column is rotatably arranged in the outer frame. Threads are arranged on both sides of the midpoint position of the second rotating column, and the two thread directions are opposite. A threaded sleeve is screwed on each thread, and the threaded sleeve is fixedly connected with the corresponding connecting plate.

[0012] In some embodiments of the present invention, several clamping and feeding units are arranged in an arc shape, and the direction of the arc is inclined downward. A pushing and pulling unit is arranged on each outer frame, and the pushing and pulling unit is used to adjust the height position of the outer frame.

[0013] In some embodiments of the present invention, the trajectory of the telescopic movement of the pushing and pulling unit is an arc.

[0014] A continuous casting and rolling production line includes a copper rod clamping and conveying mechanism; It further includes an electric furnace, a holding furnace, a filtering device, a continuous casting machine, a primary cooling system, a continuous rolling mill, a secondary cooling system, an oiling device, and a coiling machine; The electric furnace, the holding furnace, the filtering device, the continuous casting machine, the primary cooling system, the conveying mechanism, the continuous rolling mill, the secondary cooling system, the oiling device, and the coiling machine are arranged along the copper rod conveying direction. The continuous casting machine is erected at a high place, the continuous rolling mill is placed on the ground, and the conveying mechanism conveys the copper rod in an arc shape.

[0015] Through the technical solution of the present invention, the following technical effects can be achieved: By adopting the method of winding the copper rod with a winding wire, a fully enclosed clamping method for the circumferential outer wall of the copper rod can be achieved, which effectively improves the clamping effect and avoids slipping. At the same time, by utilizing the rolling movement of the winding wire, the copper rod can be transported while being wound, thereby improving the stability of copper rod transportation. In addition, by utilizing the flexible characteristics of the winding wire, a buffering effect can be simultaneously exerted on the copper rod, thereby avoiding pulling damage to the copper rod itself due to speed fluctuations during transportation, facilitating the protection of the copper rod and improving the processing quality of the copper rod.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this invention belongs. The terms used in the description of this invention are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0021] As Figures 1 to 4 shown, a copper rod clamping and conveying mechanism of the present invention includes a plurality of pinch conveying units 200 arranged along the conveying direction of the copper rod 100, and the pinch conveying units 200 are used to convey the copper rod 100; The pinch conveying unit 200 includes a wire coil 201, the wire coil 201 is composed of side pulling parts 202 located on both sides and a winding part 203 located in the middle, and the wire coil 201 is wound around the copper rod 100 through the winding part 203. The two side pulling parts 202 are used to tighten the winding part 203. When the two side pulling parts 202 rotate self - rotatably, the winding part 203 turns and rolls and squeezes to convey the copper rod 100.

[0022] In the present invention, the conveying direction of the copper rod 100 can be various conveying modes such as linear conveying and arc conveying. Its specific conveying mode is related to the actual processing process. The arrangement mode of the plurality of pinch conveying units 200 is the same as the conveying direction of the copper rod 100. In this way, the plurality of pinch conveying units 200 can simultaneously perform clamping and conveying processing on the copper rod 100, and the plurality of pinch conveying units 200 have an intermittent supporting effect on the copper rod 100, avoiding the downward bending deformation of the copper rod 100 due to its own gravity and affecting the processing quality of the copper rod 100; The wire coil 201 is wound on the outer wall of the copper rod 100. The cross - sectional shape of the wire coil 201 is circular. The part of the wire coil 201 located on the copper rod 100 is the winding part 203, and the part of the wire coil 201 located outside the copper rod 100 is the side pulling part 202. When the two side pulling parts 202 rotate in the same direction, the two side pulling parts 202 will simultaneously drive the winding part 203 to turn and roll. At this time, the winding part 203 rolls on the outer wall of the copper rod 100. Due to the friction between the winding part 203 and the copper rod 100, the winding part 203 can continuously convey the copper rod 100. At the same time, because the winding part 203 is wound around the copper rod 100, the outer wall of the copper rod 100 can be comprehensively squeezed and fixed from the entire circumferential direction of the copper rod 100, effectively improving the clamping effect and avoiding the phenomenon of slipping; It should be noted that since the wire coil 201 itself is a flexible structure, the wire coil 201 can provide a certain buffering effect for the copper rod 100 while winding and fixing the copper rod 100. This buffering effect can offset the speed fluctuation when the copper rod 100 is conveyed, thereby improving the stability when the copper rod 100 is conveyed, and improving the processing quality of the copper rod 100, and avoiding damage to the copper rod 100 caused by its speed fluctuation; In actual use, the number of turns of the winding wire 201 wound around the copper rod 100 can be one turn or multiple turns. The specific number is related to the difficulty of turning the winding wire 201. In some common devices, the number of turns of the winding wire 201 can be set to one turn. The two side pulling parts 202 are mainly used to pull the winding part 203 so that the winding part 203 is tightened on the copper rod 100. At this time, the copper rod 100 is in a hoisting state. The winding wire 201 can be made of materials with high temperature resistance, corrosion resistance, wear resistance, and good flexibility. Specifically, it can be made of silicone rubber, fluororubber, polytetrafluoroethylene, etc. It can also be used in a way that combines a hose and a steel strand inside the hose or other ways. As long as it can meet the requirements of this case, it is within the protection scope of this case.

[0023] Since the winding part 203 is wound around the outer wall of the copper rod 100 and the winding part 203 needs to turn over and convey the copper rod 100, the movement directions of the two closest positions on the winding part 203 are opposite. If these two positions come into contact with each other, then when the winding part 203 turns over, self-abrasion will occur on the winding part 203 itself, which is likely to cause damage to the winding wire 201. Therefore, it is necessary to separate and limit the two closest positions on the winding part 203. When the number of turns of the winding part 203 is one turn, as Figure 4 shown, just staggering the positions of the two side pulling parts 202 can achieve the separation effect. When the number of turns of the winding part 203 is multiple turns, it is only necessary to separate and limit adjacent turns. In some embodiments, the separation effect can also be achieved by setting spacers, small wheels, etc.

[0024] Optimized based on the above implementation, the distance between the two side pulling parts 202 can be adjusted. When the distance between the two side pulling parts 202 changes, the diameter of the winding part 203 will change. At this time, the winding part 203 can be wound around copper rods 100 with different diameters, so as to clamp and convey copper rods 100 with different sizes and specifications. At the same time, when the copper rod 100 initially passes through the winding part 203, the diameter of the winding part 203 can also be enlarged to facilitate the passage of the copper rod 100.

[0025] When the winding portion 203 winds and conveys the copper rod 100, if the position of the winding portion 203 on the winding wire 201 remains unchanged, the winding wire 201 will only use the winding portion 203 in a specific area thereof to work. After long-term use, this position is prone to wear, while other positions of the winding wire 201 cannot be fully utilized. Therefore, in order to avoid this phenomenon, the position of the winding portion 203 on the winding wire 201 is adjustable, that is, by changing the position of the winding portion 203 on the winding wire 201, the winding wire 201 can use its own different positions to convey the copper rod 100, so that the winding wire 201 can be fully utilized; in actual use, a toggle structure can be provided to push the winding portion 203 to move, or the position of the winding portion 203 can be adjusted by pushing the copper rod 100 to move on the winding wire 201. Specifically, Figure 5 As shown, the toggle structure can be a moving platform 212, the position of the moving platform 212 can be adjusted, and two inclined arms 213 are relatively rotatably arranged on the moving platform 212, each inclined arm 213 is connected to the moving platform 212 through an elastic body 215, and an extrusion wheel 214 is rotatably arranged at the end of the inclined arm 213, and the two extrusion wheels 214 are respectively located on both sides of the copper rod 100. The two elastic bodies 215 can provide elastic force for the two extrusion wheels 214, so that the extrusion wheels 214 are in contact with the outer wall of the copper rod 100, and when the moving platform 212 is adjusted, the extrusion wheels 214 are in contact with the outer wall of the copper rod 100. When the platform 212 is in the position, the copper rod 100 is pushed by the two extrusion wheels 214 to adjust the position of the copper rod 100, and the rotating connection setting of the inclined arm 213 on the movable platform 212 can facilitate the clamping of copper rods 100 of different diameters, and at the beginning, the copper rod 100 can pass through the gap between the two extrusion wheels 214 by pushing the two inclined arms 213 apart; of course, in some embodiments, two relatively arranged cylinders, rollers and other structures can also be used to achieve the clamping and adjustment functions of the position of the copper rod 100.

[0026] Optimized in the above implementation, the number of the winding wires 201 in the pinching unit 200 is at least two, and the winding directions of the winding parts 203 on each of the winding wires 201 are opposite; In the present invention, at least two winding wires 201 can be provided in each clamping unit 200 to increase the contact area with the surface of the copper rod 100 and the number of points of action on the copper rod 100, thereby improving the conveying stability of the copper rod 100; by setting the winding direction of each winding part 203, the forces acting on the copper rod 100 by two adjacent winding parts 203 wound on the copper rod 100 can be offset each other, thereby ensuring that the copper rod 100 is smoothly conveyed along its conveying direction, and avoiding the situation where only one winding wire 201 is provided and the winding part 203 is only wound once, because the pulling parts 202 on both sides are tightened, the winding tightening force of the winding part 203 on the copper rod 100 will act obliquely on the copper rod 100, causing the force-bearing position of the copper rod 100 to tilt.

[0027] Optimized based on the above implementation, such as Figures 3 to 4 As shown, the pinch unit 200 further includes an outer frame 211 and a first rotating column 204 corresponding to each of the winding wires 201. The first rotating column 204 is rotatably arranged in the outer frame 211. Two moving sleeves 205 are slidably arranged on the first rotating column 204 relatively, and the first rotating column 204 and the moving sleeves 205 rotate synchronously. A first gear 206 is arranged on each of the moving sleeves 205. Both ends of the winding wire 201 are provided with a second gear 207, and the second gear 207 is meshed and connected with the first gear 206; Wherein, the moving sleeve 205 and the second gear 207 are connected by a connecting plate 210.

[0028] In the present invention, the outer frame 211 is mainly used to support the winding wire 201 and the structures thereon. When the first rotating column 204 rotates, the first rotating column 204 can drive the moving sleeve 205, the first gear 206 and the corresponding second gear 207 to rotate, so as to drive the winding wire 201 to roll up and down. When the two connecting plates 210 move relatively, they will drive the moving sleeve 205, the first gear 206 and the second gear 207 to move synchronously, so that the first gear 206 and the second gear 207 remain in a meshed state, and the positional relationship between the side pulling parts 202 is adjusted; Since the number of winding wires 201 can be multiple, the number of the first rotating columns 204 also needs to be set correspondingly multiple. The rotational power of the first rotating column 204 can be provided by a motor, and in order to improve the synchronization of the rotation of multiple first rotating columns 204, a traditional structure can be set to transmit power to multiple first rotating columns 204 simultaneously; The cross-sectional shape of the first rotating column 204 can be a polygon, an ellipse or other special shapes, so as to ensure that the moving sleeve 205 can slide on the first rotating column 204 while the moving sleeve 205 and the first rotating column 204 rotate synchronously.

[0029] Optimized based on the above implementation, such as Figure 4 As shown, the pinch unit 200 further includes a second rotating column 208 corresponding to each of the winding wires 201. The second rotating column 208 is rotatably arranged in the outer frame 211. Threads are arranged on both sides of the midpoint position of the second rotating column 208, and the two threads have opposite directions. A threaded sleeve 209 is screwed on each thread, and the threaded sleeve 209 is fixedly connected with the corresponding connecting plate 210.

[0030] By using the second rotating column 208 and two sets of threads with opposite directions thereon, when the second rotating column 208 rotates, the second rotating column 208 can drive the two threaded sleeves 209 to move synchronously in opposite directions, thereby enabling the two connecting plates 210 to move synchronously in opposite directions. The two connecting plates 210 adjust the positional relationship between the two pulling parts 202 on both sides; since the connecting plate 210 can move along the axis of the second rotating column 208 and the axis of the first rotating column 204 at the same time, the first rotating column 204 and the second rotating column 208 can guide the connecting plate 210, thereby guiding the moving direction of the second gear 207. Then, the second gear 207 is set in a curved shape, so that the two second gears 207 and the two pulling parts 202 on both sides can be kept in a corresponding misaligned state; the rotation of the second rotating column 208 can be provided by a motor, and in order to make multiple second rotating columns 208 move synchronously, a transmission structure can be used to achieve the decentralized transmission of power.

[0031] Optimized based on the above implementation, as Figure 1 shown, several of the pinch conveying units 200 are arranged in an arc shape, and the direction of the arc is inclined downward. A pushing and pulling unit 300 is provided on each of the outer frames 211, and the pushing and pulling unit 300 is used to adjust the height position of the outer frame 211.

[0032] In the present invention, the conveying direction of the copper rod 100 is an arc inclined downward. Several pinch conveying units 200 are also distributed in an arc shape and clamp and convey the copper rod 100. The pushing and pulling unit 300 is mainly used to adjust the position of the pinch conveying unit 200, and the pushing and pulling unit 300 can be installed on an external frame; During actual use, if the length of the copper rod 100 entering the continuous rolling mill each time is small, the coil 201 can be used for buffering and offsetting fluctuations. If the length of the copper rod 100 entering the continuous rolling mill each time is large, then a larger buffer zone needs to be set up for the copper rod 100, as Figure 1 shown, when the continuous rolling mill is performing rolling work, the conveyance of the copper rod 100 stops, and the continuous casting machine continuously produces the copper rod 100. At this time, the copper rod 100 can be in a curved state, and this curved state is used to store more copper rods 100. The pushing and pulling unit 300 can control the position of the pinch conveying unit 200 so that the pinch conveying unit 200 adapts to the bending deformation of the copper rod 100. When the continuous rolling mill stops rolling work and it is necessary to feed the copper rod 100 into the continuous rolling mill, several pinch conveying units 200 perform the feeding work. At this time, the curved copper rod 100 gradually changes towards a straight line shape, and the pushing and pulling unit 300 synchronously controls the position of the pinch conveying unit 200. When the feeding is completed and the continuous rolling mill continues to perform rolling work, since the continuous casting machine continuously outputs the copper rod 100, the copper rod 100 is deformed into an arc again, and the copper rod 100 is in a storage state again. Work is repeated in this way to achieve the buffering effect on the copper rod 100; in some embodiments, the pushing and pulling unit 300 can also be implemented by using other structures that can adjust the position of the pinch conveying unit 200.

[0033] Optimized based on the above implementation, such as Figure 1 As shown, the trajectory of the push-pull unit 300 during telescopic movement is an arc; When the copper rod 100 is fed, the degree of bending of the copper rod 100 gradually decreases, and the copper rod 100 remains in an arc state. Therefore, the distribution shape of the plurality of pinch-feed units 200 needs to always be arc-shaped, and the conveying direction of the pinch-feed units 200 needs to correspond to the conveying direction of the copper rod 100 in its natural state. Therefore, the movement trajectory of the push-pull unit 300 needs to be set as an arc so that the pinch-feed units 200 can meet the conveying work requirements of the copper rod 100; the push-pull unit 300 is mainly composed of an oil cylinder 301 and a push rod 302. Both the oil cylinder 301 and the push rod 302 are arc-shaped. One end of the push rod 302 is slidably inserted into the oil cylinder 301, and the other end of the push rod 302 is fixedly connected to the outer frame 211. The oil cylinder 301 can be fixed on the frame or other structures, and the telescopic movement of the push-pull unit 300 can be controlled by hydraulic oil; the number of push-pull units 300 arranged on the pinch-feed units 200 can be determined according to the actual situation.

[0034] A continuous casting and rolling production line, including a copper rod clamping and conveying mechanism; It also includes an electric furnace, a holding furnace, a filtering device, a continuous casting machine, a primary cooling system, a continuous rolling mill, a secondary cooling system, an oiling device, and a coiling machine; The electric furnace, the holding furnace, the filtering device, the continuous casting machine, the primary cooling system, the conveying mechanism, the continuous rolling mill, the secondary cooling system, the oiling device, and the coiling machine are arranged along the conveying direction of the copper rod 100. The continuous casting machine is installed at a high place, the continuous rolling mill is placed on the ground, and the conveying mechanism conveys the copper rod 100 in an arc shape.

[0035] In the present invention, the electric furnace is used to melt copper materials; the holding furnace is used to store molten copper liquid and maintain the temperature; the filtering device is used to remove gases and inclusions in the copper liquid. Specifically, the filtering device can be a rotary degasser, a ceramic filter, etc.; the continuous casting machine is used to cool the copper liquid and continuously produce the copper rod 100; the primary cooling system is used to perform preliminary cooling treatment on the produced copper rod 100 to make it preliminarily shaped; the conveying mechanism is used to feed the copper rod 100 into the continuous rolling mill, and the conveying mechanism needs to control the conveying speed of the copper rod 100; the continuous rolling mill is mainly used to perform continuous rolling processing on the copper rod 100. Here, the rolling processing can be divided into rough rolling, medium rolling, and finish rolling; the secondary cooling system cools the rolled copper rod 100 and restores the copper rod 100 to room temperature; the oiling device is used to apply an antioxidant or other protective layer on the surface of the copper rod 100; the coiling machine is used to wind up the copper rod 100 together and perform packaging for convenient transportation.

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principles of the present invention.
