Description

Technical Field

[0001] The present invention relates to the technical field of traction equipment, and in particular to a SCR continuous casting copper billet traction clamping and conveying mechanism and a traction method. Background Art

[0002] Continuous casting technology is one of the core processes in the modern metal processing industry, especially in the production of copper and copper alloys. Due to its high efficiency, continuity and energy saving, continuous casting technology is widely used in the manufacture of copper rods, copper bars and other products. As a mature copper rod production technology, SCR continuous casting technology has become the mainstream process for the production of electrical copper rods with its high production efficiency, stable product quality and excellent conductivity.

[0003] In the SCR continuous casting process, the copper liquid is cooled and solidified into a copper billet through a crystallizer, and then the copper billet is pulled out and sent to the rolling equipment through a traction mechanism. As a key equipment in the continuous casting process, the performance of the traction mechanism directly affects the forming quality, production efficiency and stability of the equipment operation of the copper billet. Traditional traction mechanisms mostly use similar structures such as conveyor wheels for extrusion and conveying or similar structures such as clamping and pulling. When using similar structures such as conveyor wheels, the pressure of the conveyor wheels on the copper billet is large due to the small contact area with the surface of the copper billet, which can easily cause deformation and damage to the surface of the copper billet. In addition, due to the small contact area, the clamping force on the copper billet is unstable, and it is easy to slip, which makes it difficult to meet the high-precision and high-efficiency production requirements. When using similar structures such as clamps for pulling, multiple sets of clamps are required to reciprocate and alternately pull the copper billet. Its running and operation methods are cumbersome, the structure is complex, and the copper billet pulling speed is unstable. Summary of the invention

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 those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0021] like Figures 1 to 5 As shown, a SCR continuous casting copper billet traction clamping and conveying mechanism of the present invention comprises a plurality of pressing and conveying units 100 distributed circumferentially around the copper billet conveying axis, and the pressing and conveying unit 100 comprises a conveying assembly 200 and a pressing assembly 300; The conveying assembly 200 includes two conveying wheels 201 and a soft belt 202 which is arranged on the two conveying wheels 201 for transmission; The pressing assembly 300 is a plurality of pressing rollers 301 arranged along the conveying direction of the copper billet. The plurality of pressing rollers 301 are used to press part of the conveying assembly 200 on the surface of the copper billet so that the conveying assembly 200 and the copper billet are in surface contact. The pressing rollers 301 are in the shape of U-shaped wheels.

[0022] In the present invention, a plurality of pressure-feeding units 100 are used to clamp and pull the copper billet generated by solidification of the crystallizer, so that the copper billet is slowly and continuously removed from the crystallizer, thereby realizing a continuous casting processing method. In order to facilitate the clamping of the copper billet, a plurality of pressure-feeding units 100 need to be distributed circumferentially around the copper billet, so as to squeeze the surface of the copper billet in multiple directions, and the extrusion method is relative extrusion to improve the clamping stability; the number of the plurality of pressure-feeding units 100 is at least two groups. If the plurality of pressure-feeding units 100 are set as one unit, then at least one unit can be arranged along the conveying direction of the copper billet; when the cross-sectional shape of the copper billet is circular, the plurality of pressure-feeding units 100 can be distributed circumferentially. When the shape of the copper billet is square or other shapes, the plurality of pressure-feeding units 100 can be relatively distributed around the copper billet circumferentially. The specific distribution form can be determined according to the mouth shape of the crystallizer; It should be pointed out that the conveying assembly 200 mainly plays a conveying role, and the pressing assembly 300 mainly plays a pressing role. The two conveying wheels 201 in the conveying assembly 200 can continuously convey the soft belt 202, and the pressing assembly 300 can be located on the inner side of the soft belt 202, and the pressing assembly 300 can generate an extrusion force toward the copper billet on the part of the soft belt 202 close to the copper billet, so that the part of the soft belt 202 is deformed and attached to the surface of the copper billet, so as to achieve a surface contact state between the soft belt 202 and the copper billet, which can increase the contact area, and then utilize the conveying wheel 201 to press the soft belt 202. The soft belt 202 continuously and evenly rotates, so that the soft belt 202 provides continuous and stable conveying power for the copper billet, realizing a surface contact rotary traction working mode; the rotary traction mode can make the traction work simpler, convenient to operate, and simplify the structure mode, and the mode of increasing the contact area can avoid slipping, improve the traction stability, and reduce the local pressure on the surface of the copper billet, which is convenient for protecting the surface of the copper billet and improving the surface flatness of the copper billet during traction; the cross section of the conveying wheel 201 can be a straight line or an arc surface, and the soft belt 202 has a certain elasticity and deformation; Since the soft belt 202 needs to continuously perform transmission motion, the pressing assembly 300 can use a plurality of pressing rollers 301, and the pressing rollers 301 can rotate synchronously with the soft belt 202, so that the plurality of pressing rollers 301 can continuously provide extrusion force for the soft belt 202, and the soft belt 202 and the pressing rollers 301 will not have relative friction motion; the plurality of pressing rollers 301 can realize multi-point contact with the soft belt 202, so that the soft belt 202 can be attached to the surface of the copper billet within a certain length range, so as to realize the surface contact state between the soft belt 202 and the copper billet, which not only ensures the stability of transmission, but also realizes the effect of increasing the contact area; by setting the shape of the pressing roller 301 to be U-shaped, the local soft belt 202 can be deformed and its shape is consistent with the surface shape of the copper billet, thereby improving the contact effect; in some embodiments, when the cross-sectional shape of the copper billet is a square or other shape, the shape of the pressing roller 301 can also be adjusted to a corresponding shape, so that the deformed shape of the soft belt 202 keeps corresponding to the outer shape of the copper billet; By adopting the surface contact traction method, the contact area between the mechanism and the copper billet surface can be effectively increased, thereby reducing the local force on the copper billet surface, facilitating the protection of the copper billet and preventing it from deformation and damage. At the same time, the increase in contact area can also help to increase friction, avoid slipping, and make the copper billet evenly stressed, thereby improving the stability of copper billet traction; by adopting the rotary traction method, the traction work can be made simpler and more convenient to operate, the structural method can be simplified, and the traction speed can be made more stable.

[0023] Since the temperature of the copper billet is relatively high, the soft belt 202 needs to have the characteristics of high temperature resistance, high wear resistance, good friction, certain flexibility and strength, so that the soft belt 202 can smoothly pull the copper billet. To achieve this purpose, the following measures can be adopted: The soft belt 202 can be made of at least one of high temperature resistant rubber, wire braiding, ceramic fiber composite material, and graphene reinforced composite material, and the style of the soft belt 202 is at least one of a multi-layer composite structure, a modular structure, or a surface texture design; High temperature resistant rubber, such as silicone rubber and fluororubber, can maintain stable performance in high temperature environment, and has good flexibility and friction; metal wire braided belt is woven from high temperature resistant metal wire, such as stainless steel, nickel alloy, etc., and the surface can be covered with high temperature resistant coating; ceramic fiber reinforced composite material is a composite of ceramic fiber and high temperature resistant resin, and has excellent high temperature resistance and wear resistance; graphene reinforced composite material has excellent strength, wear resistance and thermal conductivity, and can be used to reinforce composite materials; The multi-layer composite structure is composed of a high temperature resistant surface layer, a reinforced middle layer and a flexible bottom layer. The surface layer is made of high temperature resistant rubber or ceramic fiber for direct contact with the copper billet. The middle layer is made of metal braid or high strength fiber for enhancing the strength of the conveyor belt. The bottom layer is made of flexible material, such as silicone rubber, for adapting to the shape of the copper billet. The modular design refers to designing the soft belt 202 into multiple modules, each module is made of high temperature resistant material, and the modules are connected by hinges or flexible connectors. The surface texture design is to design concave and convex textures or grooves on the surface of the soft belt 202 to increase the friction with the copper billet and the heat dissipation performance. Of course, in addition to the above-mentioned materials and styles, other methods that can achieve the purpose of this case can also be used, which are all within the scope of protection of this case.

[0024] Optimized to the above implementation, such as Figure 1 and Figure 5 As shown, the distance between the pressing unit 100 and the copper billet conveying axis can be adjusted, and the angle between the rotation axis of the pressing roller 301 and the copper billet conveying axis can be adjusted; Since the sizes of copper billets produced by different crystallizers are inconsistent in actual use, it is necessary to flexibly set the pressure unit 100 and the pressure roller 301 to adapt to copper billets of different sizes; taking a copper billet with a circular cross-sectional shape as an example, when the diameter of the copper billet is different, the space size between the several pressure units 100 can be adjusted by adjusting the distance between the pressure unit 100 and the copper billet conveying axis, so as to facilitate the copper billet to pass through the space between the several pressure units 100, and facilitate the soft belt 202 on the pressure unit 100 to extrude and pull the copper billet. The specific adjustment work of the pressure unit 100 can be completed by the oil cylinder 402. Of course, other structures such as motors, screws, electromagnetic thrusters, etc. can also be used to achieve the position adjustment of the pressure unit 100. work; and due to the different diameters of the copper billets, in order to ensure that the local deformation shape of the soft belt 202 corresponds to the outer shape of the copper billet, it is necessary to adjust the outer curvature of the pressing roller 301 to change the local deformation curvature of the soft belt 202. Here, the pressing roller 301 can be tilted by adjusting the angle between the axis of the pressing roller 301 and the axis of the copper billet conveying. In this way, the projection of the pressing roller 301 onto the surface perpendicular to the axis of the copper billet conveying will be deformed, and the curvature of the projection will change, thereby changing the local shape of the copper billet squeezed by the soft belt 202 to achieve the purpose of deformation; in some embodiments, in order to change the local curvature of the soft belt 202, it can also be achieved by replacing the pressing roller 301 with different curvatures, or by other methods. As long as the purpose of this case can be achieved, it is within the protection scope of this case.

[0025] Optimizing the above implementation, the arrangement of the plurality of pressing rollers 301 is one of the following: unidirectional arrangement, staggered arrangement one by one, and grouped relative arrangement; Figure 7 As shown, a plurality of rollers 301 are arranged in the same direction. This arrangement is simple, easy to assemble, and has uniform traction, which can avoid local stress concentration. Figure 8 As shown, it is a relative arrangement of groups, where the groups can be two or more groups, and this arrangement can achieve a two-way balance of traction; Fig. 9 As shown, it is a staggered arrangement one by one, which can effectively prevent the copper billet from shifting or twisting during the traction process and improve the traction stability; each arrangement method has its outstanding characteristics and can be flexibly selected and used when in use, and the specific arrangement number of the pressure rollers 301 can be flexibly selected, which will not be elaborated here.

[0026] Optimized to the above implementation, such as Figure 2 and Figure 5 As shown, the arrangement of the plurality of pressing rollers 301 is arranged in the same direction; The pressing assembly 300 also includes two side strips 302 and two adjusting wheels 303. The two side strips 302 are parallel to each other. The two ends of the pressing roller 301 are rotatably mounted on the side strips 302 through connecting joints 304. Two extension plates 305 are arranged opposite to each other on each adjusting wheel 303. The two extension plates 305 on the adjusting wheel 303 are along the radial direction of the adjusting wheel 303, and the two extension plates 305 are collinear. A connecting column 306 is arranged on each extension plate 305. The two connecting columns 306 on each adjusting wheel 303 are rotatably connected to the two side strips 302 respectively. The two adjusting wheels 303 are driven by a driving wheel 307 .

[0027] In the present invention, the motor 308 can be adjusted to provide power to the driving wheel 307, so that the two adjusting wheels 303 can rotate synchronously in the same direction, and the extension plates 305 on the two adjusting wheels 303 are parallel to each other. In this way, when the two adjusting wheels 303 move synchronously, the two adjusting wheels 303 will use the corresponding two extension plates 305 and two connecting columns 306 to drive a side strip 302 to move in translation, that is, the movement form of the side strip 302 can be regarded as a similar parallelogram movement mode, and the side strips 302 on both sides will move synchronously in opposite directions, thereby driving a plurality of pressure rollers 301 to rotate, and the axis angle of the pressure roller 301 is generated. The two adjusting wheels 303 rotate synchronously, so that each roller 301 can rotate around the axis of its own center point, and each roller 301 moves synchronously, thereby limiting the center point position of several rollers 301, and avoiding that when the rotation adjustment axis of the roller 301 deviates from the center point of the roller 301, the projection of the roller 301 on the vertical plane perpendicular to the copper billet conveying axis is tilted and offset, resulting in the roller 301 being unable to extrude the shape of the local soft belt 202 into a shape corresponding to the outer surface of the copper billet, and the several rollers 301 remain parallel to each other; It should be pointed out that since the pressure roller 301 needs to rotate around its own axis, and the pressure roller 301 needs to change its angle through adjustment of the side strip 302, the connecting section 304 needs to simultaneously satisfy these two forms of movement of the pressure roller 301, that is, one end of the connecting section 304 needs to be rotatably connected to the end of the pressure roller 301, and the rotation axis coincides with the rotation axis of the pressure roller 301, and the other end of the connecting section 304 needs to be rotatably connected to the side strip 302, and the rotation axis is parallel to the axis of the connecting column 306.

[0028] Optimized to the above implementation, such as Figure 4 As shown, the conveying assembly 200 further includes a rotating motor 204 , the output end of which transmits power to a conveying wheel 201 via a torque meter 203 , and the torque meter 203 is used to detect the torque between the rotating motor 204 and the conveying wheel 201 .

[0029] The rotating motor 204 can provide a rotating power for a conveying wheel 201, thereby driving the two conveying wheels 201 and the soft belt 202 on the conveying assembly 200 to drive synchronously. The torque measuring instrument 203 is used to measure the torque between the rotating motor 204 and the corresponding conveying wheel 201. When the torque increases, the force of the soft belt 202 pulling the copper billet increases, the amount of copper billet formed in the crystallizer increases, the pulling speed is too slow, and the pulling speed needs to be increased to avoid the formed copper billet blocking the crystallizer; when the torque decreases, the force of the soft belt 202 pulling the copper billet decreases, the forming amount of the copper billet in the crystallizer decreases, the pulling speed is too fast, and the pulling speed needs to be slowed down so that the copper billet can be formed in the crystallizer; judging the forming state of the copper billet in the crystallizer by the magnitude of the pulling force is an efficient and reliable method, and the change of the pulling force directly reflects the solidification of the copper billet and the state in the crystallizer, and the dynamic adjustment of the pulling speed can be realized to ensure the stability of production and product quality; of course, in some embodiments, the above method can also be used in conjunction with real-time monitoring, automatic control systems, etc. to improve the detection accuracy, thereby improving the copper billet processing quality.

[0030] Optimizing the above implementation, the distance between the two conveying wheels 201 in the conveying assembly 200 can be adjusted.

[0031] Since the soft belt 202 will be partially deformed when being pressed by the pressing assembly 300, the distance between the two conveying wheels 201 needs to be adjustable so as to meet the traction work of copper billets of different specifications; in actual use, such as Figure 2 As shown, a fixed plate 400 and a movable plate 401 can be provided, the movable plate 401 can slide on the fixed plate 400, the two conveying wheels 201 are rotatably mounted on the fixed plate 400 and the movable plate 401 respectively, the rotating motor 204 and the adjusting motor 308 are both provided on the fixed plate 400, the movable end of the oil cylinder 402 is connected to the fixed plate 400, and the adjusting wheel 303 and the adjusting motor 308 are both rotatably mounted on the fixed plate 400; of course, in some embodiments, structures such as mounting frames and racks can also be used to support and install the above structures.

[0032] Optimized in the above implementation, both end surfaces of each conveying wheel 201 are provided with fan-shaped baffles 205 , and the baffles 205 are away from the copper billet conveying axis, and the baffles 205 are fixed relative to the axis of the conveying wheel 201 .

[0033] When the soft belt 202 is transmitted on the conveying wheel 201, in order to prevent the soft belt 202 from being separated from the conveying wheel 201, the baffle 205 can be used to block the soft belt 202. Figure 4As shown, the baffle 205 cannot be in contact with the copper billet, so the shape of the baffle 205 can be set to be fan-shaped, so that the baffle 205 and the copper billet are away from each other, and the baffle 205 and the axis of the conveying wheel 201 are relatively fixed to avoid the baffle 205 following the movement of the conveying wheel 201 and causing the baffle 205 to contact with the copper billet; of course, the shape of the baffle 205 can also be a long strip or other shapes that can have the above-mentioned functional characteristics.

[0034] Optimized to the above implementation, such as Figure 6 As shown, each baffle 205 is provided with an ear plate; A connecting rod 206 is arranged between the two baffles 205 on the same side of the two conveying wheels 201 in the conveying assembly 200. One end of the connecting rod 206 is fixed to the ear plate on one baffle 205, and the other end of the connecting rod 206 slides through the ear plate on the other baffle 205 and is connected to each other through a spring 207.

[0035] In the present invention, the arrangement of the connecting rod 206 can play a supporting effect on the two baffles 205. In actual use, each conveying wheel 201 can be supported and driven by a core shaft, and the baffle 205 can be rotatably sleeved on the core shaft. In this way, with the support of the connecting rod 206, the baffle 205 can be kept relatively fixed with the axis of the corresponding conveying wheel 201, thereby preventing the baffle 205 from rotating at will; the arrangement of the spring 207 is mainly to generate a mutually repulsive force on the two baffles 205, and the force is transmitted to the two conveying wheels 201 through the core shaft, so that a repulsive force is generated between the two conveying wheels 201, so that the two conveying wheels 201 can be conveniently opened to the soft belt 202 by the two conveying wheels 201, so that the soft belt 202 is kept in a taut state. This structural method can not only limit the direct positional relationship between the two baffles 205, so that they remain relatively stationary with the axis of the corresponding conveying wheel 201, but also allow the connecting rod 206 to slide relative to one baffle 205, and also keep the soft belt 202 in a taut state.

[0036] A traction method of a SCR continuous casting copper billet traction clamping and conveying mechanism, comprising the following steps: Adjust the angle between the axis of the pressing roller 301 and the conveying axis of the copper billet so that the pressing roller 301 changes the curvature of the part of the soft belt 202 when pressing the part of the soft belt 202, so that the curvature matches the shape of the copper billet; The copper billet processed by continuous casting passes through a plurality of pressure feeding units 100; A plurality of pressing units 100 are brought close to each other and the surface of the copper billet is pressed by using the soft belt 202; The conveying wheels 201 on each pressing and conveying unit 100 are synchronously rotated to make the plurality of soft belts 202 synchronously run in the same direction and pull and convey the copper billet; The rotation torque of the conveying wheel 201 is detected in real time, so as to detect the force applied by the pressing unit 100 when pulling the copper billet. When the pulling force is large, the amount of copper billets formed in the external crystallizer is large and cannot be pulled out of the crystallizer in time. The rotation speed of the conveying wheel 201 needs to be increased, otherwise the rotation speed of the conveying wheel 201 needs to be reduced.

[0037] By adopting this traction method, the rotation torque of the conveying wheel 201 can be detected in real time, the traction force can be indirectly monitored, and the rotation speed of the conveying wheel 201 can be dynamically adjusted. When the traction force is large, the rotation speed of the conveying wheel 201 is increased to timely pull out the copper billet in the crystallizer. When the traction force is small, the rotation speed of the conveying wheel 201 is reduced to avoid the copper billet being broken or the surface quality being reduced, thereby ensuring a stable and efficient traction process. Through surface contact traction and dynamic adjustment of the traction speed, the local stress and damage on the surface of the copper billet are reduced, the dimensional accuracy and surface quality of the copper billet are improved, the continuous and stable production process is ensured, and the production efficiency is improved.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
