Description

Technical Field

[0001] This utility model relates to the field of explosive welding technology, and in particular to a positioning structure for explosively welded nickel-steel composite plates. Background Technology

[0002] Explosive welding utilizes the high pressure, high temperature, and high-speed shock wave released instantaneously by an explosive explosion to cause two metal surfaces to collide at high speed. The jet generated by the shock wave washes away the oxide film and impurities, and forms metallic bonds through plastic deformation, melting, and atomic diffusion, ultimately achieving welding. It is mainly used to manufacture metal composite plates, etc.

[0003] Currently, in the process of explosive welding of nickel-steel composite plates, there is a lack of inter-plate positioning structure. The explosive shock wave may cause misalignment between the plates, affecting the welding quality and making it difficult to quickly pick up and put away the welded composite plates, resulting in low welding efficiency. This paper proposes a positioning structure for explosive welding of nickel-steel composite plates to solve the above problems. Utility Model Content

[0004] To address the shortcomings and defects in existing technologies, this utility model proposes a positioning structure for explosive welding of nickel-steel composite plates. This structure solves the technical problems in the background technology where, during the explosive welding of nickel-steel composite plates, the lack of an inter-plate positioning structure leads to misalignment between plates caused by the explosive shock wave, affecting the welding quality and hindering the rapid handling and placement of the welded composite plates, resulting in low welding efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A positioning structure for explosively welded nickel-steel composite plates includes a frame-shaped base. From bottom to top, a steel substrate, a nickel alloy layer, and an explosive layer are placed sequentially on the upper end of the frame-shaped base. A detonator is installed at one corner of the explosive layer. A sliding assembly is provided at the upper end of the frame-shaped base, and the steel substrate abuts against the sliding assembly. Clamping and positioning mechanisms are provided on the upper left and right sides of the center of the frame-shaped base, and these mechanisms abut against and press against the sides of the steel substrate and the nickel alloy layer. Two limiting baffles are fixedly connected to the upper end of the frame-shaped base near the rear side.

[0006] Preferably, the two limiting baffles are respectively disposed near the left and right sides of the frame base, and both limiting baffles are welded and fixed to the frame base.

[0007] Preferably, the sliding component includes a plurality of rectangular grooves disposed on the upper end of the frame base, the plurality of rectangular grooves being distributed at equal intervals, each of the plurality of rectangular grooves having a pulley fixedly installed therein, and each of the plurality of pulleys slidingly abutting against the lower end of the steel substrate.

[0008] Preferably, the clamping and positioning mechanism includes strip grooves respectively disposed on the upper left and right sides of the center position of the frame base. Connecting rods are horizontally rotatably inserted through the inner walls of both strip grooves away from the steel substrate. A lead screw is fixedly connected to one end of each connecting rod within the strip groove. The two lead screws are rotatably connected to the other inner wall of the strip groove. A connecting block is fixedly connected to one end of each connecting rod outside the strip groove. A turntable is fixedly connected to one end of each connecting block away from the connecting rod. Movable blocks are threaded onto both lead screws. Both movable blocks are slidably connected to the bottom of the strip groove. Positioning clamps are fixedly connected to the upper ends of both movable blocks.

[0010] Preferably, each of the two strip grooves has a sliding groove at its bottom, and each of the two sliding grooves has a matching slider slidably connected to it. The upper ends of the two sliders are respectively fixedly connected to the lower ends of the two movable blocks.

[0011] Compared with the prior art, the advantages of this utility model are as follows: 1. By moving the steel substrate to the upper surface of the frame base with several pulleys, and stacking the nickel alloy layer and explosive layer on the steel substrate, it is convenient to quickly pick up and put down the welding composite plate, thereby improving the welding efficiency.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4 A positioning structure for explosively welded nickel-steel composite plates includes a frame-shaped base 1. From bottom to top, a steel substrate 2, a nickel alloy layer 3, and an explosive layer 4 are placed sequentially on the upper end of the frame-shaped base 1. A detonator 5 is installed at one corner of the explosive layer 4. A sliding assembly is provided at the upper end of the frame-shaped base 1. The steel substrate 2 abuts against the sliding assembly. The sliding assembly includes several rectangular grooves 7 arranged at equal intervals on the upper end of the frame-shaped base 1. Each of the rectangular grooves 7 has a pulley 8 fixedly installed within it. The pulleys 8 slide against the lower end of the steel substrate 2. The steel substrate 2 is moved to the upper surface of the frame-shaped base 1 using the pulleys 8 in the rectangular grooves 7, and the nickel alloy layer 3 and explosive layer 4 are then stacked sequentially on the steel substrate 2. This facilitates quick and easy handling of the welded composite plate, improving welding efficiency.

[0018] A clamping and positioning mechanism is provided on the upper left and right sides of the center position of the frame-shaped base 1. The clamping and positioning mechanism abuts and presses against the sides of the steel substrate 2 and the nickel alloy layer 3. The clamping and positioning mechanism includes strip grooves 9 respectively set on the upper left and right sides of the center position of the frame-shaped base 1. A connecting rod 10 is horizontally rotatably inserted through the inner wall of the two strip grooves 9 away from the steel substrate 2. The ends of the two connecting rods 10 located in the strip grooves 9 are fixedly connected to the lead screws 11. The two lead screws 11 are rotatably connected to the inner wall of the other side of the strip grooves 9. The ends of the two connecting rods 10 located outside the strip grooves 9 are fixedly connected to the connecting blocks 12. The ends of the two connecting blocks 12 away from the connecting rods 10 are fixedly connected to the turntables 13. The two lead screws 11 are threaded with movable blocks 14. All 4 are slidably connected to the bottom of the strip groove 9. Rotating the two turntables 13 and connecting blocks 12 drives the two connecting rods 10 to rotate, so that the two connecting rods 10 drive the two lead screws 11 to rotate simultaneously. The rotation of the two lead screws 11 drives the two threaded movable blocks 14 to move horizontally along the strip groove 9 under the limiting action of the slide groove 16 and the slider 17. The two movable blocks 14 drive the positioning clamps 15 to clamp and position the steel substrate 2 and the nickel alloy layer 3, preventing the explosion shock wave from causing misalignment between the plates and ensuring the quality of the explosion welding. The upper ends of the two movable blocks 14 are fixedly connected to the positioning clamps 15. The two positioning clamps 15 are respectively pressed against the left and right sides of the steel substrate 2 and the nickel alloy layer 3. The limiting baffle 6 and the positioning clamps 15 are both made of alloy steel.

[0019] Both strip grooves 9 have a sliding groove 16 at their bottom. Each sliding groove 16 has a matching slider 17 slidably connected to it. The upper ends of the two sliders 17 are fixedly connected to the lower ends of the two movable blocks 14. When the sliders 17 move in the sliding groove 16, they can prevent the screw 11 from rotating and causing the movable blocks 14 to rotate at the same time, so that they can only move horizontally with the rotation of the screw 11. Two limiting baffles 6 are fixedly connected to the upper end of the frame base 1 near the rear side. The two limiting baffles 6 are respectively set near the left and right sides of the frame base 1. Both limiting baffles 6 are welded and fixed to the frame base 1. The two limiting baffles 6 can provide a limit for the steel substrate 2 placed on the frame base 1, preventing the steel substrate 2 from slipping off the frame base 1.

[0020] In use, the steel substrate 2, along with pulleys 8 in several rectangular grooves 7, is moved to the upper surface of the frame base 1. The nickel alloy layer 3 and explosive layer 4 are then stacked sequentially on the steel substrate 2, facilitating quick and easy placement and removal of the welding composite plate and improving welding efficiency. Rotating the turntables 13 on both sides, along with the connecting blocks 12, drives the two connecting rods 10 to rotate, causing the two connecting rods 10 to drive the two lead screws 11 to rotate simultaneously. The rotation of the two lead screws 11 causes the two threaded movable blocks 14 to move horizontally along the strip groove 9 under the limiting action of the sliding groove 16 and the slider 17. The two movable blocks 14 then drive the positioning clamp 15 to clamp and position the steel substrate 2 and the nickel alloy layer 3, preventing misalignment between the plates due to the explosive shock wave and ensuring the quality of the explosive welding.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
