Description

Technical Field

[0001] The invention relates to the technical field of metal composite strip rolling, and in particular to an anti-deformation rolling device for a copper-aluminum composite strip. Background Art

[0002] Copper-aluminum composite strip is a new type of material. It is mainly a composite material formed by combining copper plate and aluminum plate through cold rolling, hot rolling and other methods. It is usually rolled by a rolling machine. The copper-aluminum composite strip is prone to deformation during the rolling process. The deformation is generally divided into warping and rolling corrugation. The corrugation is called the wave phenomenon. In the case of excluding the material itself and equipment failure, the main reasons for the deformation of the copper-aluminum composite strip are: 1. The rolling force is too strong. During the metal rolling process, the metal material is subjected to strong tensile and extrusion forces, which will cause the deformation of the grains and intercrystalline slip. When the structure of the metal material is destroyed, it produces plastic deformation, which will change the shape of the material; 2. During the metal rolling process, there is friction between the rollers and the metal material. When the material moves, the friction will generate friction heat on its surface, causing the internal temperature to rise, causing microscopic deformation of the grains, and thus causing the shape of the material to change; 3. The temperature on the top and bottom of the composite strip is uneven. During the rolling process, the composite strip will be cooled by spraying cooling water, but the cooling water sprayed on the top of the composite strip will flow to both sides before flowing away. The contact time between the cooling water and the composite strip is longer, so the temperature on the top of the composite strip is relatively faster, and the cooling water sprayed on the bottom of the composite strip will drip directly due to the influence of gravity, making the contact time between the bottom of the composite strip and the cooling water shorter, and the cooling effect is weaker, resulting in a temperature difference between the top and bottom of the composite strip, and the temperature difference will affect the change of the grains.

[0003] After searching, the related technology (CN118080572A) discloses a rolling device for copper-aluminum composite plates, which includes a machine table, a rolling component is fixed between the inside and the top of the machine table, and moving components are fixed on both sides of the outside of the machine table. The rolling component includes a bearing, a lower roller, a first motor, a hydraulic cylinder, a first bearing seat, an upper roller and a second motor. Bearings are fixed on both sides of the inside of the machine table, and the lower roller is fixed between the inside of the bearing located in the middle of the machine table. The outer side of the lower roller is located on one side of the outside of the machine table and is connected to the first motor. Hydraulic cylinders are fixed on both sides of the top of the machine table, and a first bearing seat is fixed on the top of the hydraulic cylinder. The upper roller is fixed between the inside of the first bearing seat and the top of the lower roller.

[0004] It can be seen from the above scheme that in the prior art, in the face of the rolling deformation problem of copper-aluminum composite plates and strips, the copper-aluminum composite plates and strips are generally corrected or restricted by physical means after they are deformed, so as to avoid deformation, rather than solving the root cause of deformation during the rolling process. However, once the copper-aluminum composite plates and strips are deformed during rolling, their structure has changed. In this case, the effect of correcting or restricting them to avoid deformation is not ideal. Therefore, it is necessary to propose an anti-deformation rolling device for copper-aluminum composite plates and strips. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides an anti-deformation rolling device that allows the copper-aluminum composite plate strip to contact with cooling water more fully.

[0006] The present invention is implemented by the following technical scheme: a four-wheel rolling mill composed of a frame, two rollers installed on the frame, and two support rollers, baffles are arranged on both sides of the four-wheel rolling mill, and openings for copper-aluminum composite plates and strips to enter and exit are arranged on the two baffles, and the baffles are combined with the frame to turn the four-wheel rolling mill into a water tank for accommodating cooling water, and a water storage tank for receiving and storing cooling water is arranged at the bottom of the four-wheel rolling mill, and a first water filling structure and a second water filling structure are respectively arranged on the water storage tank, the first water filling structure is connected to the upper half of the four-wheel rolling mill, and the second water filling structure is connected to the lower half of the four-wheel rolling mill, so that the cooling water in the water storage tank is transported to the four-wheel rolling mill to cool and lubricate the copper-aluminum composite plates and strips being rolled.

[0007] As a further improvement of the above scheme, the first water filling structure includes a first delivery pump fixedly installed on one side of the water tank, the water inlet of the first delivery pump is connected to a first water suction pipe extending into the water tank, and the water outlet of the first delivery pump is provided with a first delivery pipe extending to the upper half of the interior of the frame, and the second water filling structure includes a second delivery pump fixedly installed on the other side of the water tank, the water inlet of the second delivery pump is connected to a second water suction pipe extending into the water tank, and the water outlet of the second delivery pump is connected to a second delivery pipe extending to the lower half of the interior of the frame.

[0008] As a further improvement of the above solution, a half shell is provided on one side of each of the two baffles, and one side of the two half shells are in contact with each other to form a complete partition inside the frame.

[0009] As a further improvement of the above solution, a drain port is provided on one of the baffles, and the position of the drain port is higher than the through port.

[0010] As a further improvement of the above scheme, a first support frame corresponding to the through opening is arranged on the corresponding baffle, and two upper and lower shaft rollers are arranged on the first support frame, and the distance between the two shaft rollers is the same as the distance between the two rolling rollers.

[0011] As a further improvement of the above solution, a second support frame corresponding to the through opening is arranged on the corresponding baffle, and two mutually transmitting steel brush rollers and a motor for driving the two steel brush rollers to rotate are rotatably mounted on the second support frame.

[0012] As a further improvement of the above solution, a guide groove is provided at the bottom of the second support frame, and the guide groove is used to guide the cooling water to drain downward.

[0013] As a further improvement of the above solution, a cover for shielding the steel brush roller is provided on the second support frame.

[0014] As a further improvement of the above scheme, a partition is provided in the water storage tank to separate the water storage tank into a clean water area and a sewage area. A filter tank is set up on the partition, and the filter tank corresponds to the guide tank. Two connecting ports are provided on the partition, and filter screens are provided on both connecting ports.

[0015] As a further improvement of the above solution, two drainage flanges are provided on one side of the water storage tank, and a water supply flange is provided on the other side of the water storage tank.

[0016] Compared with the prior art, the present invention has the following beneficial effects: By arranging a water storage tank at the bottom of the frame and baffles on both sides of the frame, cooling water can be continuously transported into the four-wheel rolling mill through the water filling structure, so that the cooling water in the lower part of the four-wheel rolling mill increases the water level in a gushing manner, so as to continuously contact the back side of the copper-aluminum composite plate. Compared with the traditional method of spraying cooling water onto the copper-aluminum composite plate strip to cool it, this method belongs to immersion cooling, which allows both the front and back sides of the copper-aluminum composite plate to be fully in contact with the cooling water, so that the temperatures of the front and back sides of the copper-aluminum composite plate strip are closer when cooling, and deformation will not occur during rolling due to temperature differences. Moreover, when the rollers and the copper-aluminum composite plate strip are both in the cooling water, the lubrication effect between the two is better, which can reduce the friction between the two during rolling, thereby reducing deformation caused by friction; Compared with directly introducing the copper-aluminum composite plate into water for rolling, the immersion cooling method does not need to change the rolling path of the copper-aluminum composite plate, nor does it need to bend the copper-aluminum composite plate due to immersion, so that the copper-aluminum composite plate can always be in a straight state to avoid deformation due to bending. At the same time, due to its stronger fluidity and cyclic flow, the cooling effect of the copper-aluminum composite plate is relatively more ideal. When the cooling water flows down from both sides of the copper-aluminum composite plate, a water waterfall will be formed, so that the cooling water itself is easier to cool; The first support frame cooperates with two shaft rollers, the second support frame and two steel brush rollers, which can block the cooling water overflowing from the through port without affecting the normal rolling and transportation of the copper-aluminum composite plate and strip, so that the cooling water will not flow along the copper-aluminum composite plate and strip to the outside of the receiving range of the water storage tank, causing overflow and affecting the surrounding environment and waste, and the two steel brush rollers can not only block the cooling water when rotating, but also clean the impurities and oxide scale on the copper-aluminum composite plate and strip, so as to avoid affecting the rolling quality, and at the same time, it also avoids impurities entering the frame and causing large-scale pollution to the cooling water, and the cooling water overflowing from the through port cooperates with the steel brush roller, and the hedging produced by the two can improve the cleaning effect of the oxide scale, and can also flush the cleaned impurities and oxide scale from both sides of the copper-aluminum composite plate and strip into the guide groove, and then flow into the filter tank, so as to complete the separation of cooling water sewage and clean water, and also complete the separation of sewage and impurities, so as to increase the number of times the cooling water is used and improve its utilization rate.

[0019] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Please combine Figures 1 to 10 The anti-deformation rolling device of the copper-aluminum composite plate and strip comprises: a four-wheel rolling mill consisting of a frame 1, two rollers 2 and two support rollers 3 installed on the frame 1, baffles 11 are arranged on both sides of the four-wheel rolling mill, and the two baffles 11 are fixed to the frame 1 by screws, which are easy to disassemble and assemble, and will not affect the maintenance of the four-wheel rolling mill. The two baffles 11 are provided with openings 12 for the copper-aluminum composite plate and strip to enter and exit. The baffles 11 are combined with the frame 1 to make the four-wheel rolling mill a water tank for accommodating cooling water. A water storage tank 4 for receiving and storing cooling water is arranged at the bottom of the four-wheel rolling mill, and a first water filling structure and a second water filling structure are respectively arranged on the water storage tank 4. The first water filling structure is connected to the upper half of the four-wheel rolling mill, and the second water filling structure is connected to the lower half of the four-wheel rolling mill, so that the cooling water in the water storage tank 4 is transported to the four-wheel rolling mill to cool and lubricate the copper-aluminum composite plate and strip being rolled.

[0021] The first water filling structure includes a first delivery pump 5 fixedly installed on one side of the water storage tank 4, the water inlet of the first delivery pump 5 is connected to a first water suction pipe 6 extending into the water storage tank 4, and the water outlet of the first delivery pump 5 is provided with a first delivery pipe 7 extending to the upper half of the interior of the frame 1, and the second water filling structure includes a second delivery pump 8 fixedly installed on the other side of the water storage tank 4, the water inlet of the second delivery pump 8 is connected to a second water suction pipe 9 extending into the water storage tank 4, and the water outlet of the second delivery pump 8 is connected to a second delivery pipe 10 extending to the lower half of the interior of the frame 1.

[0022] Through the above technical scheme, the first water filling structure and the second water filling structure can respectively transport cooling water to the upper and lower areas of the four-wheel rolling mill. This allows the two sets of water filling structures to supply water to the front and back sides of the copper-aluminum composite strip respectively when the four-wheel rolling mill is rolling the copper-aluminum composite strip, so that both sides of the copper-aluminum composite strip can be fully in contact with the cooling water, and the design of the water supply being greater than the water discharge ensures that the back side of the copper-aluminum composite strip will not be unable to contact with the cooling water.

[0023] A half shell 111 is disposed on one side of each of the two baffles 11 , and one side of the two half shells 111 is in contact with each other to form a complete partition inside the frame 1 .

[0024] Through the above technical solution, the two half shells 111 are respectively arranged on the two baffles 11, which can limit the internal space of the lower half of the four-wheel rolling mill without affecting the normal disassembly and assembly of the two baffles 11, so that the incoming cooling water can be in the area between the two half shells 111, and thus flow up and be discharged through the two openings 12, thereby alleviating the water supply burden of the first water filling structure by reducing the space.

[0025] A water drain port 13 is provided on one of the baffles 11 , and the position of the water drain port 13 is higher than the through port 12 .

[0026] Through the above technical solution, since the water supply in the four-wheel rolling mill is greater than the water discharge, the excess cooling water in the four-wheel rolling mill can be discharged smoothly under the premise that the copper-aluminum composite plate and strip are fully immersed in water.

[0027] A first support frame 14 corresponding to the through opening 12 is disposed on the corresponding baffle 11 , and two shaft rollers 15 at upper and lower positions are disposed on the first support frame 14 , and the distance between the two shaft rollers 15 is the same as the distance between the two rollers 2 .

[0028] Through the above technical solution, since the copper-aluminum composite plate is in a planar state, the cooling water overflowing from the through port 12 will flow along the copper-aluminum composite plate strip, which not only easily leads to a waste of cooling water, but also the overflowing water will affect the surrounding working environment. The two first support frames 14 can block the cooling water overflowing from the through port 12 without affecting the normal rolling and transportation of the copper-aluminum composite plate strip, so that the cooling water will not flow along the copper-aluminum composite plate strip to outside the receiving range of the water storage tank 4.

[0029] A second support frame 16 corresponding to the through opening 12 is disposed on the corresponding baffle 11 , and two mutually transmitting steel brush rollers 18 and a motor 17 for driving the two steel brush rollers 18 to rotate are rotatably mounted on the second support frame 16 .

[0030] Through the above technical scheme, the two steel brush rollers 18 can not only block the cooling water when rotating, but also clean the impurities and oxide scale on the copper-aluminum composite plate and strip to avoid affecting the rolling quality. In addition, the cooling water overflowing from the through port 12 cooperates with the steel brush roller 18, and the offset produced by the two can improve the cleaning effect of the oxide scale.

[0031] A guide groove 20 is provided at the bottom of the second support frame 16 , and the guide groove 20 is used to guide the cooling water to drain downward.

[0032] Through the above technical scheme, the overflow of cooling water can prevent the cleaned impurities from entering the four-wheel rolling mill, and the guide groove 20 can pour the impurities and the cooling water that cleans the impurities into the sewage area of ​​the water storage tank 4, so as to achieve the separation of cooling water sewage and clean water, thereby increasing the number of times the cooling water is used and improving its utilization rate.

[0033] A blocking cover 19 for shielding the steel brush roller 18 is provided on the second support frame 16 .

[0034] Through the above technical solution, the blocking cover 19 can shield the steel brush roller 18 and the two gears, which can improve safety on the one hand and prevent water splashing when the steel brush roller 18 rotates at high speed on the other hand.

[0035] A partition 21 is provided in the water storage tank 4 to separate the water storage tank 4 into a clean water area and a sewage area. A filter tank 22 is set on the partition 21. The bottom of the filter tank 22 is a filter screen plate. The filter tank 22 corresponds to the guide tank 20. Two connecting ports are provided on the partition 21, and filters 23 are provided on both connecting ports.

[0036] Through the above technical solution, simple filtration of cooling water sewage can be achieved, thereby improving the utilization rate of cooling water.

[0037] Two drainage flanges are arranged on one side of the water storage tank 4 , and a water supply flange is arranged on the other side of the water storage tank 4 .

[0038] Through the above technical solution, the water supply flange and the two drainage flanges are in a closed state under normal circumstances and will only be opened when the cooling water needs to be replaced.

[0039] The implementation principle of a deformation-proof rolling device for a copper-aluminum composite plate and strip in the embodiment of the present application is: The rolling work of the copper-aluminum composite strip is carried out by multiple rolling devices in a step-by-step manner, and the rolling device of the present application is mainly responsible for the rolling work in the intermediate stage and the final stage. After the copper-aluminum composite strip is heat-treated and annealed, it is firstly rough-rolled to make the copper-aluminum composite strip initially composited, and then the initially composited copper-aluminum composite strip is finely rolled by this device; Before use, connect the external cooling water supply pipe to the water supply flange on the water storage tank 4, and then connect the two drainage flanges to the sewage pipe, and deliver cooling water to the water storage tank 4 through the cooling water supply pipe. Then, start the first delivery pump 5 and the second delivery pump 8 to continuously deliver cooling water to the frame 1. The cooling water in the frame 1 is discharged through the two ports 12, and the drainage volume of the two ports 12 is less than the water supply volume of the two irrigation structures, so that the water level in the frame 1 is higher than the two ports 12, so that the copper-aluminum composite plate and strip can fully contact with the cooling water during rolling, and when the water level overflows the drain port 13, it can be discharged through the drain port 13 to maintain the water level in the frame 1; When the copper-aluminum composite plate and strip enters the four-wheel rolling mill for rolling, it will fully contact with the cooling water in the four-wheel rolling mill, and the four-wheel rolling mill will be divided into two parts, the upper and lower parts, so that the cooling water in the upper part of the copper-aluminum composite plate and strip can cool and lubricate the front of the copper-aluminum composite plate and strip, and the cooling water in the lower part of the four-wheel rolling mill will be in a gushing state under the influence of continuous water filling by the second water filling structure, so that the cooling water is always in contact with the back part of the copper-aluminum composite plate and strip, so that the front and back sides of the copper-aluminum composite plate and strip are always in contact with the cooling water, so that when the copper-aluminum composite plate is rolled, the temperature difference between the front and back sides is smaller, thereby avoiding deformation caused by excessive temperature difference between the two. Subsequently, the cooling water in the four-wheel rolling mill will be discharged from the two ports 12 and returned to the water storage tank 4. During this process, the two shaft rollers 15 can block the cooling water flowing onto the copper-aluminum composite plate and prevent it from flowing out of the receiving range of the water storage tank 4 along the copper-aluminum composite plate. At the same time, the two steel brush rollers 18 are driven by the motor 17 to rotate in the direction of the water flow to prevent the cooling water from flowing out of the receiving range of the water storage tank 4 along the copper-aluminum composite plate. Since one side of the steel brush roller 18 is the inlet end of the four-wheel rolling mill, the two rotating steel brush rollers 18 can not only be used to intercept the overflow from the frame 1 The cooling water discharged can also clean the oxide scale produced by heat treatment on the surface of the copper-aluminum composite plate and strip, and the cleaned oxide scale flows into the guide groove 20 with the overflowing cooling water, and then flows into the filter groove 22, and then the oxide scale remains in the filter groove 22, and the cooling water infiltrates into the sewage area of ​​the water storage tank 4 from the bottom of the filter groove 22, wherein the double-filtered sewage will infiltrate the filter screen 23 into the clean water area, thereby improving the utilization rate of the cooling water, allowing the cooling water to be recycled for multiple times, and when the cooling water needs to be replaced, the cooling water in the sewage area can be discharged, and new cooling water can be transported to the water storage tank 4.

[0040] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
