Description

Technical Field

[0001] This utility model relates to the field of explosive welding block technology, and in particular to a high-temperature resistant explosive welding block. Background Technology

[0002] The explosive welding block is a square ring made of aluminum and steel. The upper layer is aluminum and the lower layer is steel. The upper and lower layers are welded and fixed by explosive welding (due to process limitations, the aluminum guide rod and steel claw cannot be directly welded using this welding process). During connection, the steel plate of the explosive welding block is welded to the steel claw in the electrolytic aluminum tank, and the weld conducts electricity. The aluminum plate of the explosive welding block is welded to the aluminum guide rod in the electrolytic aluminum tank.

[0003] However, most existing explosive weld blocks are planar welds between steel and aluminum, with limited welding contact area, which cannot form a more effective interlocking connection. The welding strength is generally low. In addition, the high temperature generated by explosive welding cannot be fully conducted and released along the solid weld block, resulting in high thermal stress. Utility Model Content

[0004] The purpose of this invention is to provide a high-temperature resistant explosion welding block to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant explosive welding block, comprising an aluminum plate and a steel plate, wherein the aluminum plate is located on top of the steel plate, and the aluminum plate and the steel plate are explosively welded together. The lower surface of the aluminum plate is provided with multiple conical teeth, and the upper surface of the steel plate is provided with multiple conical teeth. Multiple sets of diamond-shaped heat dissipation channels are opened inside the aluminum plate and the steel plate. Multiple sets of through holes are opened on the front and back of the aluminum plate and the front and back of the steel plate.

[0006] The bottom of the steel plate is provided with an elastic base, and a limit plate is fixedly connected to one side wall of the elastic base. The elastic base is provided with multiple buffer grooves.

[0007] As a preferred embodiment of this utility model, the plurality of conical teeth one and the plurality of conical teeth two are arranged alternately.

[0008] The above technical solution enables the aluminum plate and the steel plate to mesh in an interlocking tooth shape, thereby increasing the interface contact area.

[0009] As a preferred embodiment of this utility model, the size and shape of the aluminum plate are consistent with those of the steel plate.

[0010] The above technical solution enables the aluminum plate and steel plate to be stably and explosively welded together.

[0011] As a preferred embodiment of this utility model, the two ends of the plurality of rhomboid heat dissipation channels correspond to the positions of the plurality of through holes, and are internally connected.

[0012] Through the above technical solution, the diamond-shaped heat dissipation channel releases heat, and the through holes expel heat and gas.

[0013] In a preferred embodiment of this utility model, one end of the aluminum plate and one end of the steel plate are both located inside the limiting plate, and one end of the aluminum plate and one end of the steel plate are both attached to the inner wall of the limiting plate.

[0014] Through the above technical solution, the limiting plate abuts the aluminum plate and the steel plate, positions them, and enhances the stability of the explosive welding process.

[0015] As a preferred embodiment of this utility model, the limiting plate is made of aluminum alloy.

[0016] The above technical solution results in high structural strength and greater stability.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model, by setting multiple conical teeth on the lower surface of the aluminum plate and multiple conical teeth on the upper surface of the steel plate, staggered with each other, allows the aluminum plate and steel plate to interlock in an interlaced tooth shape during the high-temperature fusion of explosive welding, thereby expanding the interface contact area (2 to 3 times larger than that of a planar structure), reducing resistance concentration points, and increasing the welding connection strength. It transforms the linear combination into a three-dimensional interlocking structure, improving shear resistance. The multiple diamond-shaped heat dissipation channels and through holes can release the high temperature of the explosion and discharge the gas generated during explosive welding, which can greatly reduce thermal strain.

[0019] 2. By setting a limiting plate, this utility model can position the aluminum plate and steel plate during explosive welding, avoiding misalignment of the aluminum plate and steel plate caused by the skewed force of the explosive, ensuring gradual and stable welding, improving the welding success rate and quality. The elastic base can absorb the explosive impact energy and reduce the overall vibration and deformation of the weld block. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 4 This utility model provides a technical solution for a high-temperature resistant explosion welding block:

[0027] Example 1:

[0028] according to Figure 1 , Figure 2 and Figure 3 As shown, a high-temperature resistant explosive welding block includes an aluminum plate 1 and a steel plate 2. The aluminum plate 1 is located on top of the steel plate 2, and the aluminum plate 1 and the steel plate 2 are explosively welded together. The lower surface of the aluminum plate 1 is provided with multiple conical teeth 6, and the upper surface of the steel plate 2 is provided with multiple conical teeth 7. Multiple sets of diamond-shaped heat dissipation channels 9 are opened in the interior of the aluminum plate 1 and the interior of the steel plate 2. Multiple sets of through holes 5 are opened on the front and back of the aluminum plate 1 and the front and back of the steel plate 2.

[0029] Multiple conical teeth 6 and multiple conical teeth 7 are staggered. The size and shape of the aluminum plate 1 are the same as those of the steel plate 2. The two ends of the multiple diamond-shaped heat dissipation channels 9 correspond to the positions of multiple sets of through holes 5, and are internally connected.

[0030] In practical use, this high-temperature resistant explosive welding block, during the explosive welding process of aluminum plate 1 and steel plate 2, has multiple conical teeth 6 on the lower surface of aluminum plate 1 and multiple conical teeth 7 on the upper surface of steel plate 2 staggered. During the high-temperature fusion of explosive welding, aluminum plate 1 and steel plate 2 interlock in an interlaced tooth-like meshing pattern, expanding the interface contact area (2 to 3 times larger than a planar structure), reducing resistance concentration points, and increasing the welding connection strength. It transforms the linear combination into a three-dimensional interlocking structure, improving shear resistance and stability of the explosive welding block. During explosive welding, the high temperature of the explosion causes thermal stress to be generated inside aluminum plate 1 and steel plate 2. The heat is released along multiple rhomboid heat dissipation channels 9 and discharged through the through holes 5. At the same time, the gas generated during explosive welding can be discharged. By forming rhomboid heat dissipation channels 9 inside the welding block through laser processing, thermal strain can be greatly reduced.

[0031] Example 2:

[0032] Based on Example 1, such as Figure 1 and Figure 4 As shown, the bottom of the steel plate 2 is provided with an elastic base 4, which is made of polyurethane (Shore A80 hardness). A limiting plate 3, made of 6061-T6 aluminum alloy, is fixedly connected to one side wall of the elastic base 4. The elastic base 4 has multiple buffer grooves 8. One end of the aluminum plate 1 and one end of the steel plate 2 are located inside the limiting plate 3. One end of the aluminum plate 1 and one end of the steel plate 2 are attached to the inner wall of the limiting plate 3. The limiting plate 3 is made of aluminum alloy.

[0033] In practical use, this high-temperature resistant explosive welding block, before explosive welding, places aluminum plate 1 and steel plate 2 on top of each other inside a limiting plate 3, with one end of aluminum plate 1 and one end of steel plate 2 attached to the inner wall of the limiting plate 3. This aligns and limits aluminum plate 1 and steel plate 2, preventing misalignment of aluminum plate 1 and steel plate 2 due to the explosive force during explosive welding, ensuring gradual and stable welding, and improving welding success rate and quality. The elastic base 4 can absorb the explosive impact energy and reduce the overall vibration and deformation of the welding block. The multiple buffer grooves 8 effectively ensure that the elastic base 4 can fully deform and absorb the explosive impact force, while reducing the counterweight mass.
