Description

Technical Field

[0001] This utility model relates to the field of explosive welding auxiliary equipment technology, specifically an explosive hardening support base. Background Technology

[0002] Explosive hardening welding is a composite processing technology that utilizes the energy of explosive detonation to achieve metal joining and surface strengthening. Its principle involves controlling the instantaneous high-temperature, high-pressure shock wave generated by the detonation of explosives, causing high-speed collisions and atomic bonding between the surfaces of the metals to be welded. Simultaneously, the plastic deformation generated by the explosion promotes the formation of a high-hardness hardened layer on the material surface. This technology requires no external heat source, and the welding process is completed in milliseconds. It can reliably join dissimilar metals such as steel and aluminum, titanium and copper, with a hardened layer depth reaching several millimeters, significantly improving the wear and corrosion resistance of components. Compared to traditional welding, it has advantages such as a smaller heat-affected zone, higher bonding strength, and wider applicability, and is widely used in aerospace, shipbuilding, and automotive industries, especially suitable for processing complex structures or difficult-to-weld materials. However, this technology also faces certain challenges in practical applications: due to the lack of a sturdy base support, simple earthen pits are often used to mitigate the explosive impact, but this may lead to uneven diffusion of the impact force, thus affecting the finished product. Existing technologies may already have solutions to these problems, but this application aims to provide an alternative or replacement technical solution. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution: an explosive hardening support base, comprising: an underground base, a fitting support frame, and a locking key, wherein the locking key is mounted on the fitting support frame, the underground base is inserted into the ground, the fitting support frame is movably connected to the underground base, the locking key is movably inserted into the underground base, a shock wave reflection adjustment component is installed on the underground base, and a bidirectional positioning component is installed on the fitting support frame. The shock wave reflection adjustment component comprises: a honeycomb aluminum shock-absorbing layer, a ceramic-metal composite layer, and a ceramic-metal composite top.

[0004] The honeycomb aluminum shock-absorbing layer is installed inside the underground base, the ceramic-metal composite layer is installed on the honeycomb aluminum shock-absorbing layer, the ceramic-metal composite top is installed on the ceramic-metal composite layer, and the ceramic-metal composite top is installed inside the underground base;

[0005] It should be noted that, in the above process, a pit is first dug in the ground, the underground base is lowered into the pit, and the surrounding soil is filled in to secure it. Then, the fitting support frame is placed on top of the underground base, and the locking key installed on it will fit and be fixed inside the underground base. The fitting connection key on the fitting support frame and the fitting connection groove on the underground base can be precisely aligned and fitted, making the underground base and the fitting support frame a complete unit. Simultaneously, the bidirectional positioning component will stably support the metal plate to be welded. In summary, the underground base is thus properly fixed. During explosive hardening welding underground, the impact force generated by the explosion is transmitted to the interior of the underground base through the through-hole of the fitted support frame. The impact force first contacts the ceramic-metal composite top, which dissipates and disperses the force to the bottom of the underground base. Subsequently, the impact force first touches the ceramic-metal composite layer. After being blocked by it, the residual force is evenly absorbed and gradually decomposed by the honeycomb aluminum shock-absorbing layer. This process effectively avoids the problems of shock wave rebound and uneven dissipation, and ultimately enables the metal plate to be welded to be tightly bonded to the second layer of welding metal covering it.

[0006] Preferably, the bidirectional positioning support assembly includes: a plurality of side-view protrusions, a plurality of bearing triangular blocks, a plurality of conforming plastic blocks, and a metal plate to be welded;

[0007] Several of the side-view protrusions are respectively installed on both sides of the underground base, several of the bearing triangular blocks are respectively installed on the fitting support frame, several of the fitting plastic blocks are respectively installed on several of the bearing triangular blocks, and the metal plate to be welded is movably connected to several of the fitting plastic blocks.

[0008] It should be noted that, as described above, multiple supporting triangular blocks are arranged on the upper sides of the fitting support frame, and the installation directions of multiple fitting plastic blocks on both sides are opposite to each other. When the impact force generated by the explosion comes into contact with the metal plate to be welded, the multiple fitting plastic blocks, due to their opposite orientation, can effectively prevent displacement or shifting, thereby ensuring that the position of the metal plate material to be welded remains relatively fixed during the explosive hardening welding process. At the same time, multiple side-view protrusions play a key fixing role when the underground base is buried underground through their own root-like protrusions. Even when facing the violent vibration of the explosion shock wave, the underground base can still be stably rooted in the ground with the help of these protrusions, avoiding positional displacement due to impact force. This design further ensures the stability of the metal plate to be welded during the welding process, ultimately resulting in a better welded product.

[0009] Preferably, the side-view protrusions are provided with root-like protrusions;

[0010] Preferably, the supporting triangular block is provided with an explosion guide and release groove;

[0011] Preferably, the fitting support frame is provided with a fitting connection key;

[0012] Preferably, the underground base is provided with a fitting connection groove.

[0013] Beneficial effects

[0014] This utility model provides an explosive hardening support base. It offers the following advantages compared to existing technologies: This explosive hardening support base, through a shock wave reflection adjustment component, allows the residual shock waves released during explosive hardening welding of the metal plate to be welded, supported by the interlocking support frame, to diffuse and release evenly within the underground base. This effectively prevents secondary rebound of the shock waves from causing vibration damage to the metal plate to be welded. Simultaneously, the bidirectional positioning component not only firmly fixes the underground base to the ground but also stably supports the metal plate to be welded, ensuring it adheres tightly to the interlocking support frame. This guarantees efficient and stable fusion of the metal plate to be welded with the other metal plate covering it during the welding process, ultimately improving the overall quality of the welded product.

Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0021] Example

[0022] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-3 As shown, an explosive hardening support base includes: an underground base 1, a fitting support frame 2, and a locking key 3. The locking key 3 is installed on the fitting support frame 2. The underground base 1 is inserted into the ground. The fitting support frame 2 is movably connected to the underground base 1. The locking key 3 is movably inserted into the underground base 1. A shock wave reflection adjustment component is installed on the underground base 1. A bidirectional positioning support component is installed on the fitting support frame 2. The shock wave reflection adjustment component includes: a honeycomb aluminum shock-absorbing layer 4, a ceramic-metal composite layer 5, and a ceramic-metal composite top 6. The honeycomb aluminum shock-absorbing layer 4 is installed inside the underground base 1, and the ceramic-metal composite layer 5 is installed inside the underground base 1. The ceramic-metal composite top 6 is installed on the honeycomb aluminum shock-absorbing layer 4 and on the ceramic-metal composite layer 5, and is installed inside the underground base 1; the supporting bidirectional positioning component includes: a plurality of side-view protrusions 7, a plurality of bearing triangular blocks 8, a plurality of fitting plastic blocks 9, and a metal plate 10 to be welded; the plurality of side-view protrusions 7 are respectively installed on both sides of the underground base 1, the plurality of bearing triangular blocks 8 are respectively installed on the fitting support frame 2, the plurality of fitting plastic blocks 9 are respectively installed on the plurality of bearing triangular blocks 8, and the metal plate 10 to be welded is movably connected to the plurality of fitting plastic blocks 9.

[0023] According to the appendix Figure 1-3The process involves first digging a pit in the ground, lowering the underground base 1 into the pit, and then backfilling it with soil for fixation. Next, the fitting support frame 2 is placed above the underground base 1, and the locking key 3 installed on it will fit and fix itself within the underground base 1. The fitting connection key on the fitting support frame 2 and the fitting connection groove on the underground base 1 can be precisely aligned and fitted, allowing the underground base 1 and the fitting support frame 2 to be completely connected as a whole. Simultaneously, the bidirectional positioning component will stably support the metal plate 10 to be welded. In summary, the underground base 1 is properly fixed below ground. During explosive hardening welding, the impact force generated by the explosion will be transmitted to the interior of the underground base 1 through the through-hole of the fitting support frame 2. The impact force first contacts the ceramic-metal composite top 6, which dissipates and disperses the force to the bottom of the underground base 1. Subsequently, the impact force will first touch the ceramic-metal composite layer 5, which, after being blocked, will have its residual force evenly absorbed and gradually decomposed by the honeycomb aluminum shock-absorbing layer 4. This process effectively avoids the impact... The uneven rebound and dispersion of the shock wave ultimately ensures that the metal plate 10 to be welded and the second layer of welding metal covering it can be tightly bonded together. Multiple supporting triangular blocks 8 are arranged on the upper sides of the fitting support frame 2, while the multiple fitting plastic blocks 9 on both sides are installed in opposite directions. When the impact force generated by the explosion comes into contact with the metal plate 10 to be welded, the multiple fitting plastic blocks 9, due to their opposite orientation, can effectively prevent it from shifting or moving, thereby ensuring that the position of the metal plate 10 to be welded remains relatively fixed during the explosive hardening welding process. At the same time, multiple side-view protrusions 7, through their own root-like protrusions, play a key fixing role when the underground base 1 is buried underground. Even in the face of the violent vibration of the explosion shock wave, the underground base 1 can still be stably rooted in the ground with the help of these protrusions, avoiding positional displacement due to impact force. This design further ensures the stability of the metal plate 10 to be welded during the welding process, ultimately resulting in a better welded product.
