Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figure 1-6 As shown, the present invention proposes a forging and welding additive manufacturing device, including an air hammer 1. The workbench of the air hammer 1 has a fixed cavity 2. The top of the workbench of the air hammer 1 is provided with two L-shaped plates 3 extending into the fixed cavity 2. The fixed cavity 2 is provided with a driving structure 4. The output end of the driving structure 4 is connected to the L-shaped plates 3 to drive the L-shaped plates 3 to move. Sliding blocks 5 are provided on opposite sides of the two L-shaped plates 3. Spacing adjustment structures 6 are provided on opposite sides of the two L-shaped plates 3. Spacing adjustment structures 6 are connected to the sliding blocks 5 to adjust the spacing between the two sliding blocks 5. Clamping plates 8 are provided on opposite sides of the two sliding blocks 5. Disassembly and assembly structures 7 are provided on opposite sides of the two sliding blocks 5. Disassembly and assembly structures 7 are connected to the clamping plates 8 to disassemble and assemble the clamping plates 8.

[0027] In this invention, the air hammer 1 can be used to perform additive forging and welding on metal. Before the metal is forged and welded, the drive structure 4 can move the two L-shaped plates 3 to opposite sides. Under the action of the sliding block 5, the spacing adjustment structure 6, and the disassembly and assembly structure 7, the two clamping plates 8 will move to opposite sides. The two clamping plates 8 can clamp and fix the metal, ensuring the stability of the metal during forging and welding. At the same time, no operator is required, avoiding injury to the operator caused by the force generated by the hammer.

[0028] The clamping plate 8 is one of the following: V-shaped clamping plate, arc-shaped clamping plate, and flat clamping plate. Before fixing the metal, the clamping plate 8 can be quickly installed and removed through the disassembly structure 7, so that the clamping plate 8 can be quickly replaced and adapted to metals of different shapes.

[0029] It should be noted that the shape of the clamping plate 8 can be adjusted according to the shape of the additive metal to be forged and welded, and is not limited to the above-mentioned shapes.

[0030] The spacing between the two sliding blocks 5 can be adjusted by the spacing adjustment structure 6. Under the action of the disassembly and assembly structure 7, the spacing between the two clamping plates 8 can be adjusted, thereby expanding the clamping range of the original two clamping plates 8, so that the two clamping plates 8 can clamp and fix metal of larger or smaller size.

[0031] In embodiment 1, the disassembly and assembly structure 7 includes mounting blocks 71 installed on opposite sides of the two sliding blocks 5. The top of each mounting block 71 is provided with a connecting groove 72. A horizontal plate 73 is installed on opposite sides of the two clamping plates 8. A connecting block 74 is installed at the bottom of each of the two horizontal plates 73. The two connecting blocks 74 are slidably connected to the inside of the two connecting grooves 72 respectively. A positioning component 75 for fixing the connecting block 74 is provided on the back of each mounting block 71.

[0032] When the clamping plate 8 needs to be replaced, first use the positioning component 75 to release the fixing of the connecting block 74, then pull the clamping plate 8 upward. The clamping plate 8 will drive the horizontal plate 73 and the connecting block 74 to move upward. When the connecting block 74 is disengaged from the connecting groove 72, the clamping plate 8 can be removed. At the same time, after installing clamping plates 8 of different shapes, the positioning component 75 can fix the connecting block 74, thereby ensuring the stability of the connecting block 74 and the clamping plate 8 after installation, and preventing the clamping plate 8 from sliding up and down due to the impact force on the metal during forging and welding.

[0033] In embodiment 2, the positioning component 75 includes a U-shaped plate 751 installed on opposite sides of two mounting blocks 71. Positioning grooves 752 are provided on opposite sides of the two connecting blocks 74. Positioning rods 753 extending into the positioning grooves 752 are slidably connected to opposite sides of the two U-shaped plates 751. The positioning rods 753 are slidably connected to the positioning grooves 752. Springs 754 are provided on the outer side of the two positioning rods 753. The opposite sides of the two springs 754 are respectively connected to the outer side of the two positioning rods 753. The opposite sides of the two springs 754 are respectively connected to the opposite side wall of the inner cavity of the two U-shaped plates 751. Pull rings 755 are installed on opposite ends of the two positioning rods 753.

[0034] When it is necessary to disengage the connecting block 74, pull the pull ring 755 to the side away from the clamping plate 8. The pull ring 755 will drive the positioning rod 753 to move away from the positioning groove 752. When the positioning rod 753 disengages from the positioning groove 752, the connecting block 74 will be disengaged. At the same time, the positioning rod 753 will compress the spring 754. When the pull ring 755 is released, the positioning rod 753 will move towards the positioning groove 752 under the rebound force of the spring 754. When installing clamping plates 8 of different models, first pull the pull ring 755, then make the connecting block 74 slide into the interior of the connecting groove 72. Finally, release the pull ring 755. The positioning rod 753 will slide into the interior of the positioning groove 752 under the rebound force of the spring 754, thus ensuring the stability of the installation of the connecting block 74, thereby ensuring the stability of the installation of the clamping plate 8.

[0035] In embodiment three, the spacing adjustment structure 6 includes a sliding groove 61 opened on the opposite side of two sliding blocks 5, two L-shaped plates 3 are slidably connected to the inside of the two sliding grooves 61 respectively, and multiple adjustment grooves 62 are opened on the top of the L-shaped plates 3. An adjustment rod 63 extending into the sliding groove 61 is slidably connected to the top of the sliding block 5. The adjustment rod 63 is slidably connected to the adjustment groove 62. A pull block 64 is installed on the top of the adjustment rod 63. A limit component 65 is provided inside the sliding groove 61.

[0036] When the distance between the two sliding blocks 5 needs to be adjusted, pull the pull block 64 upward. The pull block 64 will drive the adjusting rod 63 to move upward. When the adjusting rod 63 disengages from the corresponding adjusting groove 62, the sliding block 5 can slide on the outside of the L-shaped plate 3, thereby adjusting the distance between the two sliding blocks 5. After the adjustment is completed, when the adjusting rod 63 passes through the sliding block 5 and slides into the corresponding adjusting groove 62, the stability of the sliding block 5 after the distance adjustment can be ensured. By adjusting the distance between the two sliding blocks 5, the clamping range of the original two clamping plates 8 is expanded, so that the two clamping plates 8 can clamp and fix metal of larger or smaller size.

[0037] The limiting component 65 includes limiting grooves 651 formed on the front and rear side walls of the inner cavity of the sliding groove 61. Limiting blocks 652 are installed on the front and back of the L-shaped plate 3. The two limiting blocks 652 are slidably connected to the inside of the two limiting grooves 651 respectively. The limiting grooves 651 and the limiting blocks 652 can limit the sliding block 5, preventing the sliding block 5 from separating from the L-shaped plate 3 when it slides on the outside of the L-shaped plate 3.

[0038] In embodiment four, the drive structure 4 includes a servo geared motor 41 mounted on the right side of the air hammer 1. A bidirectional screw 42 extending into the interior of the fixed cavity 2 is mounted on the output shaft of the servo geared motor 41. Threaded blocks 43 are threaded to both ends of the fixed cavity 2 with opposite thread directions. The bottoms of the two L-shaped plates 3 are respectively connected to the tops of the two threaded blocks 43. Two sliding rods 44 are installed between the left and right side walls of the inner cavity of the fixed cavity 2. The two threaded blocks 43 are slidably connected to the outside of the two sliding rods 44.

[0039] When the servo geared motor 41 is started, the output shaft of the servo geared motor 41 will drive the bidirectional screw 42 to rotate. Under the action of the thread thrust, the two ends of the bidirectional screw 42 with opposite thread directions will drive the two threaded blocks 43 to move to the opposite side or the opposite side respectively. The two threaded blocks 43 will drive the two L-shaped plates 3 to move to the opposite side or the opposite side respectively, so that the two clamping plates 8 can move to the opposite side or the opposite side, so that the two clamping plates 8 can clamp and fix the metal.

[0040] When the two threaded blocks 43 move, the two slide rods 44 can limit and guide the threaded blocks 43, ensuring the stability of the movement of the threaded blocks 43 while preventing the threaded blocks 43 from rotating.

[0041] It should be noted that the air hammer 1 has a complete control system in the prior art, and the servo geared motor 41 is electrically connected to the control system, so the servo geared motor 41 can be controlled through the control system.

[0042] Working principle:

[0043] In use, the metal to be forged and welded is placed on the worktable of the air hammer 1. According to the shape of the metal, the clamping plate 8 is quickly disassembled by the disassembly and assembly structure 7, and then the clamping plate 8 that matches the shape of the metal is installed. At this time, according to the size of the metal, the distance between the two clamping plates 8 is adjusted by the distance adjustment structure 6. Then, the servo reduction motor 41 is started, so that the two clamping plates 8 move to the opposite side, thereby clamping and fixing the metal to be forged and welded. At this time, the air hammer 1 can be used to perform additive forging and welding on the metal.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
