Description

Technical Field

[0001] The present invention relates to the technical field of copper rod processing, in particular 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 the fields of wires and cables, enameled wires, electrical equipment, etc. 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 communications, the market demand for high-quality copper rods continues to grow. The copper rod continuous casting and rolling production line, as the mainstream process for copper rod production, has the advantages of high efficiency, continuity, and energy saving. However, its production process puts forward higher technical requirements for the clamping and transportation of copper rods.

[0003] During the continuous casting and rolling process of copper rods, the copper rods produced by the continuous casting machine need to be moved into the continuous rolling mill with the help of a clamping and conveying mechanism. Traditional clamping and conveying mechanisms generally use steel belts, conveyor chains, or similar structures distributed on the upper and lower sides or the front and rear sides of the copper rod to squeeze the copper rod and use the steel belts, conveyor chains, or similar structures to transmit the copper rods. However, this clamping method can only achieve a partial 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 poor and slippage is prone to occur. In some equipment, conveyor wheels or conveyor rollers are also used to clamp and convey the copper rods, which also have the above-mentioned problems. In addition, during the continuous rolling process, since the copper rods cannot be continuously introduced into the continuous rolling mill at a constant speed, the conveying speed of the copper rods fluctuates. This fluctuation is directly related to the continuous rolling interval of the continuous rolling mill, the instantaneous speed of the copper rod output by the continuous casting machine, etc., and the traditional clamping and conveying mechanism cannot effectively buffer this fluctuation, resulting in local pulling and deformation of the copper rods during the continuous casting and rolling process, affecting the processing quality of the copper rods. 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 technology.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] A copper rod clamping and conveying mechanism comprises a plurality of clamping and conveying units arranged along a conveying direction of the copper rod, wherein the clamping and conveying units are used to convey the copper rod;

[0007] The clamping unit includes a wire winding, which consists of side pulling parts located on both sides and a winding part located in the middle. The wire winding 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, the winding part rolls and squeezes the copper rod.

[0008] In some embodiments of the present invention, the positions of the two side pulling parts are staggered.

[0009] In some embodiments of the present invention, the distance between the two side pulling parts is adjustable.

[0010] In some embodiments of the present invention, the position of the winding portion on the winding wire is adjustable.

[0011] In some embodiments of the present invention, the number of the winding wires in the pinching unit is at least two, and the winding directions of the winding parts on the winding wires are opposite.

[0015] In some embodiments of the present invention, the plurality of pinching units are arranged in an arc shape, and the arc direction is inclined downward, and each outer frame is provided with a push-pull unit, and the push-pull unit is used to adjust the height position of the outer frame.

[0016] In some embodiments of the present invention, the trajectory of the push-pull unit during telescopic movement is arc-shaped.

[0017] A continuous casting and rolling production line includes a copper rod clamping and conveying mechanism;

[0018] It also includes an electric furnace, a holding furnace, a filter unit, a continuous casting machine, a primary cooling system, a continuous rolling mill, a secondary cooling system, an oiling unit, and a coiler;

[0020] The technical solution of the present invention can achieve the following technical effects:

[0021] By adopting the method of winding the wire around the copper rod, a fully enclosed clamping method of the outer circumference of the copper rod can be achieved, which effectively improves the clamping effect and avoids slipping. At the same time, the winding movement of the wire can be used to transport the copper rod while winding it, thereby improving the stability of copper rod transportation.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described 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.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] like Figures 1 to 4 As shown, a copper rod clamping and conveying mechanism of the present invention comprises a plurality of clamping and conveying units 200 arranged along the conveying direction of the copper rod 100, wherein the clamping and conveying units 200 are used to convey the copper rod 100;

[0035] The clamping unit 200 includes a wire winding 201, which consists of side pulling parts 202 located on both sides and a winding part 203 located in the middle, and the wire winding 201 is wound on 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, the winding part 203 rolls and squeezes the copper rod 100.

[0036] In the present invention, the conveying direction of the copper rod 100 can be a variety of conveying modes such as linear conveying and arc conveying. The specific conveying mode is related to the actual processing process. The arrangement of the plurality of pinching units 200 is the same as the conveying direction of the copper rod 100. In this way, the plurality of pinching units 200 can simultaneously clamp and convey the copper rod 100, and the plurality of pinching units 200 have an intermittent support effect on the copper rod 100, thereby preventing the copper rod 100 from bending downward due to its own gravity, which affects the processing quality of the copper rod 100.

[0037] The winding wire 201 is wound around the outer wall of the copper rod 100. The cross-sectional shape of the winding wire 201 is circular. The part of the winding wire 201 located on the copper rod 100 is the winding part 203, and the part of the winding wire 201 located outside the copper rod 100 is the side pulling part 202. When the pulling parts 202 on both sides rotate in the same direction, the pulling parts 202 on both sides will simultaneously drive the winding part 203 to 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 transport the copper rod 100. At the same time, since the winding part 203 is wound around the copper rod 100, the outer wall of the copper rod 100 can be fully squeezed and fixed from the entire circumferential direction of the copper rod 100, which effectively improves the clamping effect and avoids slipping.

[0038] It should be noted that, since the winding wire 201 itself is a flexible structure, the winding wire 201 can provide a certain buffering effect for the copper rod 100 while being wound and fixed thereon. This buffering effect can offset the speed fluctuation of the copper rod 100 during transportation, thereby improving the stability of the copper rod 100 during transportation and improving the processing quality of the copper rod 100, thereby preventing the copper rod 100 from being damaged by the speed fluctuation.

[0039] In actual use, the number of turns of the winding wire 201 wrapped around the copper rod 100 can be one turn or multiple turns. The specific number is related to the difficulty of winding the winding wire 201. In some commonly used equipment, the number of turns of the winding wire 201 can be set to one turn; the pulling parts 202 on both sides are mainly used to pull the winding part 203 to tighten the winding part 203 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 high-temperature resistant, corrosion-resistant, wear-resistant and flexible materials, specifically silicone silicone, fluororubber, polytetrafluoroethylene and other materials, or a hose and steel stranded wire in the hose can be used in combination or other methods. As long as it can meet the requirements of this case, it is within the scope of protection of this case.

[0040] Since the winding portion 203 is wound on the outer wall of the copper rod 100, and the winding portion 203 needs to be rolled and transported, the movement directions of the two closest positions on the winding portion 203 are opposite. If the two positions are in contact with each other, the winding portion 203 itself will produce self-abrasion when the winding portion 203 is rolled, 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 portion 203. When the number of winding turns of the winding portion 203 is one turn, as shown in FIG. Figure 4 As shown, the separation effect can be achieved by simply staggering the positions of the two side pulling parts 202. When the winding number of the winding part 203 is multiple turns, it is necessary to separate and limit the two adjacent turns. In some embodiments, the separation effect can also be achieved by setting spacers, small wheels, etc.

[0041] Optimized in 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 of different diameters, thereby clamping and conveying copper rods 100 of different sizes. 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 expanded to facilitate the passage of the copper rod 100.

[0042] When the winding portion 203 is winding and conveying 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 area is prone to wear and tear, while other areas 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 rotatable on the moving platform 212. Each inclined arm 213 is connected to the moving platform 212 through an elastic body 215. The end of the inclined arm 213 is rotatably provided with an extrusion wheel 214. 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 contact the outer wall of the copper rod 100. When the moving platform 212 is adjusted, the two 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 initially, the copper rod 100 can pass through the gap between the two extrusion wheels 214 by moving 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 copper rod 100 position.

[0043] Optimizing the above embodiment, the number of the winding wires 201 in the pinching unit 200 is at least two, and the winding directions of the winding portions 203 on the winding wires 201 are opposite;

[0044] 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 exerted on the copper rod 100 by two adjacent winding parts 203 wound on the copper rod 100 can offset each other, thereby ensuring that the copper rod 100 is conveyed smoothly along its conveying direction, 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.

[0045] Optimized to the above implementation, such as Figures 3 and 4 As shown, the pinching unit 200 further includes an outer frame 211 and a rotating column 1 204 corresponding to each of the winding wires 201. The rotating column 1 204 is rotatably disposed within the outer frame 211. Two movable sleeves 205 are relatively slidably disposed on the rotating column 1 204, and the rotating column 1 204 and the movable sleeves 205 rotate synchronously. Each of the movable sleeves 205 is provided with a gear 1 206. Both ends of the winding wire 201 are provided with a gear 207, and the gear 207 is meshed with the gear 1 206.

[0046] The movable sleeve 205 and the second gear 207 are connected via a connecting plate 210 .

[0047] In the present invention, the outer frame 211 is mainly used to support the winding wire 201 and the structure thereon. When the rotating column 1 204 rotates, the rotating column 1 204 can drive the movable sleeve 205, the gear 1 206 and the corresponding gear 2 207 to rotate, thereby driving the winding wire 201 to roll. When the two connecting plates 210 move relative to each other, they will drive the movable sleeve 205, the gear 1 206 and the gear 2 207 to move synchronously, thereby keeping the gear 1 206 and the gear 2 207 in meshing state and adjusting the position between the side pull parts 202. Relationship; since the number of winding wires 201 can be multiple, the number of rotating columns 204 also needs to be set accordingly. The rotational power of the rotating column 204 can be provided by a motor, and in order to improve the synchronization of the rotation of multiple rotating columns 204, a traditional structure can be set to transmit power to multiple rotating columns 204 at the same time; the cross-sectional shape of the rotating column 204 can be polygonal, elliptical or other special shapes, so that the movable sleeve 205 can slide on the rotating column 204 while the movable sleeve 205 and the rotating column 204 rotate synchronously.

[0048] Optimized to the above implementation, such as Figure 4 As shown, the clamping unit 200 also includes a rotating column 208 corresponding to each of the winding wires 201. The rotating column 208 is rotatably arranged in the outer frame 211. Threads are provided on both sides of the midpoint of the rotating column 208, and the directions of the two threads are opposite. A threaded sleeve 209 is screwed on each thread, and the threaded sleeve 209 is fixedly connected to the corresponding connecting plate 210.

[0049] By utilizing the two threaded arrangements on the rotating column 208 and the opposite directions thereon, when the rotating column 208 rotates, the rotating column 208 can drive the two threaded sleeves 209 to move synchronously in the opposite directions, thereby causing the two connecting plates 210 to move synchronously in the opposite directions, and the two connecting plates 210 adjust the positional relationship of the pulling parts 202 on both sides; since the connecting plates 210 can move along the axis of the rotating column 208 and the axis of the rotating column 1 204 at the same time, the rotating column 1 204 and the rotating column 208 can guide the connecting plates 210, thereby guiding the moving direction of the gear 207, and then the gear 207 is set to a curved shape, so that the two gears 207 and the pulling parts 202 on both sides can maintain a corresponding staggered state; the rotation of the rotating column 208 can be provided by a motor, and in order to make multiple rotating columns 208 move synchronously, a transmission structure can be used to realize the dispersed transmission of power.

[0050] Optimized to the above implementation, such as Figure 1 As shown, the plurality of pinching units 200 are arranged in an arc shape, and the arc direction is inclined downward. A push-pull unit 300 is provided on each outer frame 211 , and the push-pull unit 300 is used to adjust the height position of the outer frame 211 .

[0051] In the present invention, the conveying direction of the copper rod 100 is an arc-shaped inclined downward, and a plurality of pinching and conveying units 200 are also distributed in an arc shape and clamp and convey the copper rod 100. The push-pull unit 300 is mainly used to adjust the position of the pinching and conveying unit 200, and the push-pull unit 300 can be installed on an external frame;

[0052] In actual use, if the length of the copper rod 100 entering the continuous rolling mill each time is small, it can be buffered by the coil 201 to offset the fluctuation. 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, such as Figure 1 As shown, when the continuous rolling mill is rolling, the copper rod 100 stops being transported, and the continuous casting machine continues to produce the copper rod 100. At this time, the copper rod 100 can be in a bent state, which is used to store more copper rods 100. The push-pull unit 300 can control the position of the pinching unit 200 so that the pinching unit 200 can adapt to the bending deformation of the copper rod 100. When the continuous rolling mill stops rolling and needs to feed the copper rod 100 into the continuous rolling mill, several pinching units 200 perform feeding work. At this time, the copper rod 100 in the bent state gradually changes towards a straight shape, and the push-pull unit 300 synchronously controls the position of the pinching unit 200. When the feeding is completed, the continuous rolling mill continues to roll. Since the continuous casting machine continues to output 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. This work is repeated, thereby achieving a caching effect on the copper rod 100. In some embodiments, the push-pull unit 300 can also be implemented using other structures that can adjust the position of the pinching unit 200.

[0053] Optimized to the above implementation, such as Figure 1 As shown, the trajectory of the push-pull unit 300 during telescopic movement is an arc;

[0054] Since the bending degree of the copper rod 100 gradually decreases when feeding, and the copper rod 100 maintains an arc-shaped state, the distribution shape of the multiple pinching units 200 needs to always be arc-shaped, and the conveying direction of the pinching unit 200 needs to correspond to the conveying direction of the copper rod 100 in the natural state. Therefore, the movement trajectory of the push-pull unit 300 needs to be set to an arc, so that the pinching unit 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 of which 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 a frame or other structure, and the telescopic movement of the push-pull unit 300 can be controlled by hydraulic oil; the number of push-pull units 300 on the pinching unit 200 can be determined according to actual conditions.

[0055] A continuous casting and rolling production line includes a copper rod clamping and conveying mechanism;

[0056] It also includes an electric furnace, a holding furnace, a filter unit, a continuous casting machine, a primary cooling system, a continuous rolling mill, a secondary cooling system, an oiling unit, and a coiler;

[0057] The electric furnace, holding furnace, filtering device, continuous casting machine, primary cooling system, conveying mechanism, continuous rolling mill, secondary cooling system, oiling device and coiler are arranged along the conveying direction of the copper rod 100, and 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 100 in an arc shape.

[0058] In the present invention, an electric furnace is used to melt copper material; a holding furnace is used to store molten copper liquid and maintain the temperature; a filtering device is used to remove gas and inclusions in the copper liquid, and the specific filtering device can be a rotary degasser, a ceramic filter, etc.; a continuous casting machine is used to cool the copper liquid and continuously produce copper rods 100; a primary cooling system is used to perform preliminary cooling treatment on the produced copper rods 100 to give them a preliminary shape; a conveying mechanism is used to feed the copper rods 100 into a continuous rolling mill, and the conveying mechanism needs to control the conveying speed of the copper rods 100; the continuous rolling mill is mainly used to perform continuous rolling processing on the copper rods 100, and the continuous rolling processing can be divided into rough rolling processing, intermediate rolling processing and finishing rolling processing; a secondary cooling system cools the rolled copper rods 100 and restores the copper rods 100 to room temperature; an oiling device is used to apply a layer of anti-oxidant or other protective layer on the surface of the copper rods 100; a coiler is used to roll the copper rods 100 together and package them for easy transportation.
