Technical Field
[0001] The utility model belongs to the technical field of explosion welding, and in particular relates to a modular combination structure based on an explosion welding composite die. Background Art
[0002] Explosive welding involves placing explosives on the base and backing plates. The resulting high-pressure shock wave, generated by the explosives, causes high-speed collisions, plastic flow, and partial melting of the metal surfaces, resulting in a metallurgical bond. Its core principle is to achieve atomic-level bonding between metals through dynamic plastic deformation. In explosive welding, composite molds are crucial for ensuring welding quality and efficiency.
[0003] The utility model patent, publication number CN 209850095 U, provides a curved metal plate explosive welding structure, comprising a box body with a hinged lid at the top; a base plate at the bottom of the box body, a support frame mounted above the base plate, and a transparent top and bottom box seated on the top of the top plate. The box contains a uniform thickness of explosive powder and a detonator for detonating the explosives, which extends above the lid. The top surface of the base plate and the bottom surface of the top plate have corresponding curved surfaces, and the bottom contour of the box aligns with the top surface of the top plate. The curved metal plate explosive welding structure is fabricated into a corresponding curved surface based on the curved surface of the base plate, with a gap set between the two. Finally, explosive powder for explosive welding is applied to the top surface of the top plate. The curved base plate and the top plate are combined by explosive welding to form a bimetallic curved explosive welding structure, breaking through the limitations of traditional flat-plate explosive welding.
[0004] In the existing technology, during the use of a curved metal plate explosive welding structure, there is no targeted control of the impact force generated by the explosion during the welding process. At the moment of the explosive explosion, the huge impact force can easily cause excessive deformation of the base plate and the composite plate, and even damage the workpiece. Therefore, it is necessary to make improvements to this and propose a modular combination structure based on an explosive welding composite mold. Utility Model Content

[0030] It should be noted that space is provided for explosion welding by setting up an explosion welding box body 1 and an explosion welding box cover 2, and the explosion welding box cover 2 set on the top of the explosion welding box body 1 adopts an inserting design and is slidingly connected to the inside of the explosion welding box body 1. This connection method facilitates the opening and closing of the explosion welding box cover 2, while ensuring the sealing of the structure.
[0031] It should be noted that a base plate 3 is provided for installing a substrate that requires explosion welding, and a Japanese-shaped through hole 4, a connecting hole 5 and a conical groove 6 are provided in the base plate 3 to facilitate the installation of an airbag 7 and the inflation and deflation of the airbag 7. During explosion welding, the huge impact force generated by the explosion acts on the airbag 7, and the airbag 7 absorbs energy by compressing the internal gas, converting the impact force into the internal energy of the gas, thereby effectively reducing the damage to the workpiece and the mold caused by the impact force.
[0032] It should be noted that by providing reinforcing ribs 8 inside the base plate 3 and on both sides of the corresponding day-shaped trough body, the structural strength of the base plate 3 is enhanced, making it less likely to deform when subjected to the huge impact force during the explosive welding process, thereby ensuring the overall stability of the mold.
[0033] It should be noted that the top plate 9 is provided for installing the composite plate that needs to be explosively welded and the explosives required for the explosive welding, and the detonator 10 is provided to facilitate ignition of the explosives.
[0034] like Figure 2 and Figure 3 As shown, in this embodiment, communication holes 11 are formed within the base plate 3 and on opposite sides of the sun-shaped trough. An air inlet pump 12 and an air outlet pump 13 for inflating and deflating the airbag 7 are fixedly mounted thereon. Dust screens 14 are provided on the exterior of the communication holes 11. The provision of communication holes 11 facilitates the installation of the air inlet pump 12 and the air outlet pump 13. The provision of the air inlet pump 12 and the air outlet pump 13 for inflating and deflating the airbag 7 enhances the energy absorption efficiency of the airbag 7. The provision of the dust screen 14 prevents dust and other impurities from entering the air inlet pump 12 and the air outlet pump 13.
[0035] like Figure 2 and Figure 5 As shown, in this embodiment, a bidirectional screw 15 and a limit rod 16 are respectively provided inside the explosive welding box body 1 and on the corresponding two sides of the bottom plate 3. The bidirectional screw 15 passes through the two side plates 17 and is threadedly connected thereto. The bidirectional screw 15 is inserted into the interior of the explosive welding box body 1 and is rotatably connected thereto. The interior of the explosive welding box body 1 is rotatably connected with a worm gear 18 and a worm 19 that mesh with each other. The worm gear 18 is fixedly connected to the bidirectional screw 15. A handle 20 is fixedly installed on one side of the worm 19, and the handle 20 passes through one side of the explosive welding box body 1 and is rotatably connected thereto. A plurality of insertion rods 21 are fixedly installed on one side of the two side plates 17 that are close to each other. The plurality of insertion rods 21 are all inserted into the interior of the bottom plate 3 and are slidably connected thereto. The explosive welding box body 1 is fixedly connected to the limit rod 16, and the limit rod 16 passes through the two side plates 17 and is slidably connected thereto. A frame structure is formed by setting a bidirectional screw rod 15, a limit rod 16 and two side plates 17, and a worm wheel 18, a worm 19 and a handle 20 are set. The handle 20 rotates to drive the worm 19 to rotate, and then the worm wheel 18 rotates to realize the rotation of the bidirectional screw rod 15, thereby adjusting the distance between the two side plates 17, and cooperating with the insertion rod 21 on the side plate 17 to be inserted into the interior of the base plate and slidably connected with it to fix the base plate.
[0036] It should be noted that the handle 20 passes through one side of the explosive welding box body 1, that is, the handle 20 is located outside the explosive welding box body 1, that is, the distance between the two side plates 17 can be adjusted by rotating the handle 20 from the outside of the explosive welding box body 1.
[0037] like Figure 1 and Figure 2 As shown, in this embodiment, the top plate 9 is a split structure, and the tops of the two top plates 9 are each provided with a threaded rod 22. The threaded rod 22 is inserted into the interior of the top plate 9 and is rotatably connected thereto. The threaded rod 22 passes through the explosive welding box cover 2 and is threadedly connected thereto. The split top plate 9 facilitates the installation of a second plate between the two top plates 9. The threaded rod 22 allows the top plate 9 to move up and down when the threaded rod 22 is rotated, thereby adjusting the height of the second plate and controlling the distance between the second plate and the base plate, thereby ensuring the effect of explosive welding.
[0038] It should be noted that the threaded rod 22 is rotatably connected to the top plate 9, that is, when the threaded rod 22 rotates, the top plate 9 will only move up and down and will not rotate with it, thereby ensuring the stability of the composite plate.
[0039] like Figure 1 and Figure 2 As shown, in this embodiment, a curved protective plate 23 is fixedly mounted on the top of the top plate 9. The protective plate 23 passes through the top of the explosive welding box cover 2 and is slidably connected thereto. An elastic layer is also fixedly mounted on the top of the top plate 9. The protective plate 23 protects the threaded rod 22. During explosive welding, the explosives are located in the area between the two protective plates 23, which helps to concentrate the explosive energy on the base plate and the composite plate. The elastic layer also provides a buffering and protective effect during explosive welding.
[0040] like Figure 2 and Figure 4 As shown, in this embodiment, a doubler support assembly is provided on each corresponding side of the two top plates 9. The doubler support assembly includes a support plate 24 rotatably connected to the top plate 9, and a support torsion spring 25 is provided at the lower portion of the connection between the top plate 9 and the support plate 24. The doubler support assembly is provided for mounting the doubler plates, and the structure of the support plate 24 and the support torsion spring 25 are designed to support the doubler plates before explosive welding. During explosive welding, the doubler plates are pressed downward and can be separated from the support plate 24.
[0041] like Figure 1 As shown, in this embodiment, a plurality of mutually cooperating buckles 26 are fixedly installed on the outer sides of the explosion welding box body 1 and the explosion welding box cover 2. By providing the buckles 26, a tight connection between the explosion welding box body 1 and the explosion welding box cover 2 is achieved, ensuring stability during the explosion welding process.
[0042] During actual use, the substrate is installed on the bottom plate 3, and the air bag 7 is blown by the air pump 12, the base plate is clamped by adjusting the handle 20, and then the threaded rod 22 is adjusted to ensure the distance between the double plate and the substrate, and the double plate and explosives are installed on the double plate support assembly and connected to the detonator 10, and then the explosion welding box cover 2 is buckled on the explosion welding box body 1, and the buckle 26 is closed, and finally the explosive is detonated by the detonator 10 to realize explosion welding. The operation is simple and easy to promote and apply.
[0043] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent variation of the above embodiment made according to the technical essence of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
