Description

Technical Field

[0001] This utility model relates to the technical field of electricity metering box production equipment, specifically a metal box bending and welding integrated machine. Background Technology

[0002] In the production process of electricity metering boxes, the processing of metal boxes includes two key steps: bending and welding. In the traditional production model, these two processes are often carried out on different equipment. First, the operator bends the metal sheet on the bending equipment to obtain a semi-finished product, and then transfers it to the welding equipment for welding. This step-by-step production method requires a lot of manpower to complete the transfer of workpieces, which not only increases the company's labor costs, but also consumes extra time in the transfer process, resulting in low production efficiency. Meanwhile, during the manual transfer of semi-finished products, the workpieces are easily affected by external forces such as collisions and squeezing, which leads to a decrease in the positioning accuracy of the workpieces. When these poorly positioned workpieces enter the welding process, problems such as misalignment and incomplete welding will occur at the weld joints, which seriously affects the product quality of the electricity metering box and reduces the product qualification rate. In addition, the separate setting of bending equipment and welding equipment requires a large production space, which is not conducive to the rational layout of the production line and also increases the company's costs in terms of equipment purchase and site rental.

[0019] like Figures 1-4As shown, a second slide groove 311 is fixedly provided at the upper end of the second partition plate 302. Auxiliary rings 312 are fixedly installed at both ends of the second slide groove 311. A guide rod 313 is provided between the two auxiliary rings 312.

During the welding process, with the synergistic effect of the first drive motor 305, the second drive motor 315 and the electric push rod 319, the laser welding head 320 can be driven to move flexibly in three-dimensional space to achieve precise welding of the workpiece and effectively improve the quality of the product.

[0020] Working principle: In use, first place the metal sheet to be processed on the lower die 202, carefully adjust its position so that the part to be bent is precisely aligned with the bending groove 203 at the upper end of the lower die 202; at this time, the operator holds one end of the metal sheet with one hand to steadily maintain the stability of the sheet and prevent it from shifting during bending, while the other end of the sheet rests naturally on the bending groove 203, ready for bending. Then, the bending assembly 2 is started by controlling switch 4, and the hydraulic drive cylinder 204 begins to work, pushing the upper die 205 along the vertical... Moving downwards in a straight line, the protrusion at the lower end of the upper die 205 perfectly matches the bending groove 203 of the lower die 202. During the downward pressure of the protrusion, the operator can use their other hand to support the free end of the metal plate, assisting in bending upwards along the downward pressure of the upper die 205. This process, similar to using a lever principle, combines human and mechanical forces to allow the sheet metal to smoothly complete plastic deformation along the bending groove 203. This ensures accurate bending angles and reduces the potential for sheet metal skewing when the machine applies pressure alone. The electricity metering box body requires multiple bending processes. Operators can adjust the placement of the metal plate on the bending groove 203 multiple times according to design requirements, repeating the above-mentioned pressing and auxiliary bending actions until all bending steps are completed. After the bending process is completed, the operator carefully transfers the formed workpiece to the welding placement plate 303 of the welding assembly 3, holding the edge of the workpiece by hand to ensure that the workpiece maintains a stable positioning state during the welding process. Then, the welding assembly 3 is started. The first drive motor 305 drives the first threaded screw 306 to rotate, causing the first slider 308 sleeved on the screw to move the connecting plate 309 in the front-back direction. At the same time, the second drive motor 315 on the connecting plate 309 drives the second threaded screw 316 to rotate, causing the second slider 318 to move the laser welding head 320 in the left-right direction. Then, the electric push rod 319 at the lower end of the second slider 318 is used to adjust the vertical height of the laser welding head 320, ultimately achieving precise movement of the laser welding head 320 in three-dimensional space, and completing high-quality welding operations on the parts of the workpiece that need to be welded.
