Description

Technical Field

[0001] This utility model relates to the field of strip material technology, and more specifically, to a production unit and system for metal composite strip. Background Technology

[0002] Metal layered composite plates are a new type of metal composite material composed of two or more layers of metals or alloys with different physical, chemical and mechanical properties. They combine the performance advantages of different metal components, or become new multifunctional materials, or improve the performance of materials, or effectively save precious metal materials and reduce material costs by replacing rare and precious metals with common metals. Therefore, they have broad application prospects.

[0003] Currently, commonly used methods for preparing metal layered composite plates include rolling composite, explosive composite, extrusion composite, electromagnetic continuous casting, twin-crystal continuous casting, cladding casting, spray deposition, and reverse solidification. However, these methods generally suffer from drawbacks such as limited bonding strength, severe pollution, high energy consumption, complex forming processes, large strip deformation, and unstable forming quality, thus limiting the green, low-consumption, and high-quality production of metal layered composite plates.

[0004] Therefore, there is an urgent need to improve the production equipment and processes for metal layered composite panels to solve the problems of complex production processes and poor product stability in traditional layered composite materials.

[0005] Therefore, this application is hereby submitted. Utility Model Content

[0030] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0031] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0032] To address the problems of complex processes, high energy consumption, and unstable product forming quality in existing metal composite strip manufacturing processes, this utility model utilizes a transmission roller 003 for transmission, sequentially passing through each process segment. The operation is simple and easy, which can improve product forming quality and achieve green, low-consumption, and high-quality production of metal layered composite plates.

[0033] Please refer to Figure 1This utility model provides a metal composite strip production unit 100, including: a transmission roller 003 for transporting the strip; a first shearing device 110, a surface treatment device 120, a rolling device 130, and a second shearing device 140 sequentially arranged on the transmission line formed by the transmission roller 003; adjacent devices are connected by the transmission roller 003. By transporting the strip through multiple transmission rollers 003, the strip sequentially passes through the first shearing device 110, the surface treatment device 120, the rolling device 130, and the second shearing device 140 to complete the composite of two materials, and directly prepares a coil product. The process is simple and easy to implement.

[0034] In some embodiments, the production unit 100 further includes a first uncoiler 161 and a second uncoiler 162 disposed at the feed end of the production unit 100, for conveying a first strip 001 through the first uncoiler 161 and a second strip 002 of a different material from the first strip 001 through the second uncoiler 162. The specific materials of the first strip 001 and the second strip 002 are not limited. The production unit 100 provided by this invention can combine the two strips together to prepare a composite strip. The first strip 001 and the second strip 002 are combined in the rolling mill 130 and need to be conveyed separately before combination.

[0035] Furthermore, the production unit 100 also includes a coiler 163 located at the discharge end of the production unit 100, which cooperates with the first uncoiler 161 and the second uncoiler 162 to transport the strip material. The coiler 163, the first uncoiler 161, and the second uncoiler 162 provide the transmission power, allowing the two types of strip material to pass through the processing equipment at each stage in sequence.

[0036] Furthermore, the head of the first uncoiler 161 is provided with a first deflecting pinch roller 004, through which the first strip 001 is introduced and pinched. Similarly, the head of the second uncoiler 162 is provided with a second deflecting pinch roller 005, through which the second strip 002 is introduced and pinched. The first deflecting pinch roller 004 and the second deflecting pinch roller 005 are used to realize the deflection and transfer of the first strip 001 and the second strip 002.

[0037] Specifically, the first steering pinch roller 004 and the second steering pinch roller 005 are a form of the transmission roller 003. There are steering rollers, tension rollers and correction rollers in the entire process line. The entire process line is tens of meters long. The corresponding type of rotating roller is set at the appropriate position to achieve stable transmission of the strip.

[0038] Understandably, the transmission line before the rolling mill 130 is divided into a first transmission line 006 and a second transmission line 007, so that the first strip 001 is transmitted through the first transmission line 006 and the second strip 002 is transmitted through the second transmission line 007; after the rolling mill 130, since the two types of strips are composited, there is only one transmission line, called the third transmission line 008, so that the composite strip is transmitted through the third transmission line 008.

[0039] In some embodiments, the first shearing device 110 is a double-layer shear. A first strip 001 is transmitted through the upper part of the double-layer shear via a first transmission line 006, and a second strip 002 is transmitted through the lower part of the double-layer shear via a second transmission line 007. The double-layer shear is an existing device capable of performing shearing operations on the upper and lower parts separately. Both the first transmission line 006 and the second transmission line 007 pass through the double-layer shear.

[0040] In some embodiments, the surface treatment apparatus 120 includes a first surface treatment apparatus 121 and a second surface treatment apparatus 122. The first surface treatment apparatus 121 is located on a first transmission line 006, and the second surface treatment apparatus 122 is located on a second transmission line 007. Both the first surface treatment apparatus 121 and the second surface treatment apparatus 122 are located between a first shearing apparatus 110 and a rolling apparatus 130. The first surface treatment apparatus 121 and the second surface treatment apparatus 122 respectively perform surface treatment on the first strip 001 and the second strip 002 to remove oil stains, oxide layers, etc. from the surface of the strips.

[0041] Specifically, the specific processing methods of the first surface treatment equipment 121 and the second surface treatment equipment 122 are not limited, and can be surface treatment methods such as chemical film removal, mechanical brushing, electrochemical cleaning, and laser treatment.

[0042] like Figure 1 and Figure 2 As shown, the production unit 100 also includes a laser welding machine 150 corresponding to the rolling equipment 130. The laser welding machine 150 heats the dissimilar strip materials at the interface of the plates by irradiating them with the laser, and the rolling equipment 130 applies rolling pressure to the dissimilar strip materials. The laser welding machine 150 emits a rectangular shaping beam 009 to heat the two strip materials to be laminated, improving the bonding strength after lamination.

[0043] Specifically, the laser welding machine 150 provides a heat source during the laser layering process of dissimilar sheet and strip materials, and can be a CO2 laser welding machine, a semiconductor laser welding machine, or a fiber laser welding machine, etc. The rolling mill 130 provides pressure during the laser layering process of dissimilar sheet and strip materials, and can be a single-stand rolling mill, a multi-stand rolling mill, or a leveling mill, etc.

[0044] Furthermore, the second shearing device 140 includes a disc shear 141 and a scrap shear 142, for edge trimming by the disc shear 141 and for processing the waste material cut off by the disc shear 141 by the scrap shear 142. The disc shear 141 is used to trim the incompletely welded portions of the metal composite strip during the laser layer forming process, and the cut-off portions are further processed by the scrap shear 142 and then recycled.

[0045] Furthermore, an outlet shear 143 is provided after the second shearing device 140. The outlet shear 143 is used to process the composite strip after the disc shear 141. The outlet shear 143 can cut the head of the strip to obtain a composite strip product with strong bonding force.

[0046] Specifically, the disc shear 141, the edge trimmer 142, and the exit shear 143 can all be commercially available equipment that can perform their functions. The cutting process can be operated manually or controlled by a program.

[0047] The production method for preparing metal composite strip using the production unit 100 provided by this utility model is as follows: different strip steels enter the production unit 100 from the uncoilers (i.e., the first uncoiler 161 and the second uncoiler 162), are cut at the strip head by double-layer shears, and have oil stains, oxide layers, etc. removed from the surface of the strip by the surface treatment section. The strip is then laser-laminated and formed by the rolling equipment 130 and the laser welding machine 150 (i.e., the laser welding equipment). The strip is then cut at the edges by the disc shear 141 and the edge trimming shear 142, and then cut at the head and sampled by the exit shear 143. Finally, the metal composite strip is coiled by the coiler 163 to complete the production of the strip.

[0048] It should be noted that during the laser lamination forming process of dissimilar composite strips, the laser irradiation energy should exceed the melting point of the composite strip, and the surface of the composite strip should be slightly melted. After rolling, the deformation of the composite strip should be less than 25%, and a metallurgical bond should be formed between the dissimilar strips.

[0049] This utility model embodiment also provides a metal composite strip production system, including the above-mentioned production unit 100, and may further include packaging equipment and other equipment for post-processing the coil output from the winding machine 163. It may also include equipment for producing a first strip 001 and a second strip 002, etc.

[0050] The following is combined with Figure 1 and Figure 2 The working principle of the production unit 100 provided by this utility model is further explained as follows:

[0051] like Figure 1As shown, metal strips of different materials are uncoiled by the first uncoiler 161 and the second uncoiler 162 respectively. The heads of the uncoilers are equipped with steering pinch rollers (i.e., the first steering pinch roller 004 and the second steering pinch roller 005). The steel strip is introduced into the steering pinch rollers by the uncoiler, and the head of the strip is pinched. The strip is automatically cut to a fixed length by a double-layer shear. The portion of the strip exceeding tolerance and the portion with poor shape are automatically cut off at a fixed length as manually set. The cut steel plates are sent to the waste pit on the transmission side of the unit for collection. The cut steel strips enter the first surface treatment equipment 121 and the second surface treatment equipment 122 to perform surface treatment on the first strip 001 and the second strip 002 respectively. Surface treatment methods such as chemical decoction, mechanical brushing, electrochemical cleaning, and laser treatment are used to remove oil, oxide layers, and other substances from the surface of the strip. After surface treatment, the strip steel reaches the rolling mill 130 via the deflecting pinch rolls. A laser welding machine 150 irradiates the interface of the dissimilar strip steel to heat it, and the rolling mill 130 applies pressure to roll the dissimilar strip steel, thereby achieving laser lamination forming of the dissimilar strip steel. Figure 2 As shown. After laser layering and forming, the metal composite strip enters the disc shear 141 and edge trimming shear 142 via tension rollers and guide rollers to trim the incomplete welded parts of the metal composite strip during the laser layering process. The treated strip enters the exit shear 143 via guide rollers. This shearing machine can automatically perform operations such as shearing the strip head, collecting samples, and slitting according to the computer-set program. Waste material enters the waste collection device, and samples enter the sampling trolley. The sampling and labeling robot arm automatically stores the samples from the sampling trolley into the sample box and affixes labels. After shearing, the strip is sent to the tension coiler 163 for winding. The coiled steel strip is the finished metal composite strip coil. After being unloaded from the coil trolley, it is weighed by the weighing saddle and sent to the exit coil saddle to await crane transport to the finished product warehouse.

[0052] In summary, this utility model provides a production unit and system for metal composite strips. Through reasonable unit layout and suitable production methods, it achieves efficient, high-quality, and low-consumption production of different metal composite strips, solving the problems of complex production processes and poor product stability in traditional layered composite material production. By using common metals to replace rare and precious metals, it effectively saves precious metal materials, reduces material costs, and improves enterprise efficiency.

[0053] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
