Description

Technical Field

[0001] This application relates to the field of metal composite plate forming technology, and in particular to an interlayer support device for metal composite plates. Background Technology

[0002] Metal composite panels are composite panels formed by combining two or more different metal materials through a specific process. They combine the advantages of each component metal, such as strength, corrosion resistance, and thermal conductivity. Common types include titanium-steel composite panels, aluminum-steel composite panels, and copper-steel composite panels. Titanium-steel composite panels combine the corrosion resistance of titanium with the strength of steel and can be used in chemical equipment and seawater desalination plants. Aluminum-steel composite panels utilize the lightweight of aluminum and the load-bearing capacity of steel, making them suitable for transportation and building structures. Copper-steel composite panels leverage the electrical conductivity of copper and the mechanical properties of steel, and are used in power transmission and electronic equipment.

[0003] Currently, the composite processes for metal composite panels include explosive bonding, rolling bonding, and diffusion welding. Explosive bonding utilizes the shock wave generated by an explosive explosion to cause the metal plates to collide at high speed, achieving metallurgical bonding. Rolling bonding presses the metal plates together through hot or cold rolling. Diffusion welding involves the diffusion of metal atoms under high temperature and pressure to form a bond. Explosive forming is a highly efficient process in the production of metal composite panels, especially suitable for manufacturing large-area, irregularly shaped, or high-strength composite panels. It is widely used in metal plate composites. Its principle involves placing explosives between the base plate and the cladding plate using the impact of an explosion. The resulting high-pressure shock wave causes the cladding plate to impact the base plate at extremely high speed, forming plastic deformation and metallic bonding at the impact interface.

[0004] Currently, the explosive forming process for composite panels involves applying a predetermined amount of explosive to the lower panel, followed by the placement of support strips (usually copper strips) to create an impact gap between the upper and lower panels after the upper panel is placed, allowing for the release of impact force during the explosion. The structure of the metal composite panel before the explosion is as follows: Figure 1-4 As shown. Currently, during the post-explosion compounding process, due to the significant impact of the explosive, this impact force acts upwards on the upper plate (the lower plate is usually placed on the ground or an explosion platform, providing stability). Because the surface flatness of the explosive laid on the lower plate is often not precise enough, the impact force across the entire plate surface is inconsistent. Therefore, after acting on the upper plate, it causes it to shift laterally on the copper strip, resulting in misalignment between the sides of the upper and lower plates after the explosive forming process (e.g., ...). Figure 5-6 As shown in the diagram, the width of the misalignment is only a single layer of plate, and no explosive bonding has been performed. Therefore, it is necessary to saw off the misalignment area. Figure 7 As shown in the figure, this results in material waste and affects the final size of the composite board, easily leading to the rejection of composite boards that do not meet the size requirements, thus increasing production costs. Summary of the Invention

[0005] To address the aforementioned problems, this application aims to provide a metal composite plate interlayer support device. By setting continuous blocking teeth on the surface of the copper strip, the contact resistance with plate A can be effectively increased, thereby blocking the displacement of plate A after it is subjected to an explosive impact and reducing the impact displacement of plate A.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: a metal composite plate interlayer support device, wherein the support device is a copper strip arranged between plate A and plate B, the copper strip suspends and supports plate A on plate B, and forms an impact gap between plate A and plate B, and a blocking structure is provided on the upper surface of the copper strip that contacts plate A on the upper side to block the horizontal displacement of plate A after being impacted.

[0007] Furthermore, the blocking structure consists of continuous blocking teeth on the upper surface of the copper strip.

[0008] Preferably, the blocking teeth are inclined toward one side of the horizontal direction, and the blocking teeth on adjacent copper bars are arranged in opposite directions.

[0009] Preferably, the blocking teeth are also provided on the bottom surface of each copper strip, and the blocking teeth on the bottom surface are arranged in opposite directions to the blocking teeth on the top surface.

[0010] Preferably, resistance grooves are formed between the continuous resistance teeth.

[0011] The beneficial effects of this application are: by setting continuous blocking teeth on the surface of the copper strip, compared with the planar structure of the copper strip surface, it can effectively increase the contact resistance with plate A, thereby blocking the displacement of plate A after it is subjected to an explosive impact, and reducing the impact displacement of plate A.

[0012] The damming teeth are angled towards the horizontal direction, opposite to the offset direction of plate A, which further reduces the impact offset of plate A. Furthermore, the damming teeth on the lower surface of the copper strip improve its stability when placed on plate B, further enhancing its offset-damping effect on plate A.

[0031] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] See attached document Figures 1-15 The diagram illustrates an interlayer support device for a metal composite plate. This support device consists of copper strips 3 arranged between plate A (1) and plate B (2). Plate A (1) is made of titanium, and plate B (2) is made of steel, forming a titanium-steel composite plate after explosion molding. The copper strips 3 suspend and support plate A (1) on plate B (2), creating an impact gap 'a' between them. Simultaneously, the copper strips 3, acting as an intermediate layer, promote atomic diffusion between plate A (1) and plate B (2), resulting in a stronger metallurgical bond, and also improve the electrical conductivity of the composite plate.

[0033] To address the problem of material waste caused by inconsistent impact forces of explosives during explosive lamination, which leads to lateral displacement of the upper A plate 1 relative to the lower B plate 2 and necessitates sawing to correct side misalignment in the final composite board, this application provides a restraining structure on the upper surface of the copper strip 3 where it contacts the upper A plate 1. This structure hinders the horizontal displacement of the A plate 1 after impact. This restraining structure prevents the A plate 1 from sliding on the copper strip 3, increasing the sliding resistance and reducing the horizontal displacement of the A plate 1 after the explosive impact. Ultimately, this reduces the cutting width of the composite board's sides and minimizes material waste.

[0034] Specifically, such as Figure 8-9 As shown, the blocking structure consists of continuous blocking teeth 31 on the upper surface of the copper strip 3. Compared to the planar structure of the copper strip 3 surface, its toothed structure can effectively increase the contact resistance with plate A 1, thereby blocking the displacement of plate A 1 after it is subjected to an explosive impact, thus reducing the impact displacement of plate A 1.

[0035] Because plate A shifts horizontally on copper strip 3 under the impact of the explosion, in order to increase the resistance to plate A 1, such as... Figure 9 As shown, the blocking teeth 31 are inclined towards the horizontal side. When plate A is deflected in the direction of arrow b1 in the figure, the blocking teeth 31 will achieve the reverse blocking effect in the direction of arrow b2, thereby further reducing the impact displacement of plate A.

[0036] In the actual explosion process, the direction in which the impact force causes plate A to shift left and right cannot be determined, therefore... Figure 10 As shown, the blocking teeth 31 on adjacent copper strips 3 are arranged in opposite directions. With this opposite arrangement, when plate A shifts to the left or right, the blocking teeth 31, with their opposite directions of shift, effectively block the shift. When plate A shifts longitudinally back and forth, the copper strips 3 can be arranged in... Figure 11 The shape shown is designed to impede the offset of plate A in the longitudinal direction.

[0037] During the impact displacement process, plate A, while being resisted in the opposite direction by the resisting teeth 31, also acts on the copper strip 3, causing the copper strip 3 to move on plate B 2. Therefore, to improve the positional stability of the copper strip 3 on plate B 2, such as... Figure 12-13 As shown, the bottom surface of each copper strip 3 is also provided with the blocking teeth 31. The blocking teeth 31 on the bottom surface can restrict the movement (sliding) of the copper strip 3 by utilizing the increased contact resistance with the surface of the B plate when the copper strip 3 is offset by the A plate, and further restrict the displacement of the A plate.

[0038] Furthermore, the blocking teeth 31 on the bottom surface of a single copper strip 3 are arranged in opposite directions to the blocking teeth 31 on the top surface, which enables the copper strip 3 to maintain a relatively stable position in both the left and right directions, thus avoiding an increase in the displacement of plate A due to the sliding of the copper strip 3.

[0039] After supporting plates A and B with copper strip 3 to form an impact gap a, the reagent is laid in this impact gap a. Copper strip 3 is located within the reagent, which creates resistance to displacement of copper strip 3. Therefore, to increase the resistance to displacement of copper strip 3 using the reagent, such as... Figure 8 As shown, a resistance groove 3a is formed between the continuous blocking teeth 31. The applied agent can fill the resistance groove 3a. Compared with the planar copper strip 3, the agent can further increase the displacement resistance to the movement of the copper strip 3 when it is filled into the resistance groove 3a, thereby improving its stability on the surface of plate B and increasing the blocking effect on plate A, thereby further reducing the displacement of plate A and the amount of cutting on the side of the composite plate during the explosion impact.

[0040] To avoid uneven distribution of copper strips 3 on the board surface due to displacement of plate A at different locations, which would result in unequal spacing of the copper strips 3. Figure 14 As shown in the diagram, the copper strips exhibit uneven dispersion after being integrated into the composite board, which affects the consistency of the composite board's quality. Therefore, to solve this problem, such as... Figure 15 As shown, this application arranges copper strips 3 in both horizontal and vertical directions, and fixes the copper strips 3 together to form an integral copper strip frame III structure. Thus, when the A plate is displaced, the spacing between each copper strip remains consistent, so that the copper strips have high uniformity after being exploded and integrated into the A and B plates, thereby improving the consistency of the internal structure of the composite plate.

[0041] The principle of this application is as follows: During the explosive forming of the composite plate, the copper strips used have hindrance teeth. The hindrance teeth on the upper and lower surfaces of each copper strip are arranged in opposite directions. At the same time, the hindrance teeth on the same surface of adjacent copper strips are also arranged in opposite directions. Then, the copper strips are supported between plate A and plate B. Under the explosive impact, the hindrance teeth on the surface of the copper strips increase the offset resistance to plate A, thereby reducing the offset of plate A relative to plate B and reducing the amount of sawing on the side of the composite plate, thus reducing material waste.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope of protection, and all such changes and modifications fall within the scope of protection claimed by this utility model.
