Description

Technical Field

[0001] This utility model relates to the field of metal sheet stamping technology, and in particular to a multi-station stamping device for metal sheets. Background Technology

[0002] Photovoltaic modules are the core equipment for solar power generation, converting light energy into direct current (DC) through the photovoltaic effect. They consist of solar cells, encapsulation materials, glass, backsheets, frames, and junction boxes, and come in various types, including monocrystalline silicon, polycrystalline silicon, PERC, N-type, bifacial, and thin-film, each with different efficiencies, costs, and applicable scenarios. Their core performance parameters include power output, efficiency, temperature coefficient, and warranty period, and they are widely used in various photovoltaic power generation systems.

[0003] Metal sheets typically refer to flat metal products with a certain thickness and shape, made by processing metal through processes such as rolling, forging, and stamping. Generally speaking, the processing technology for thin metal sheets is called sheet metal processing, and the resulting parts are sheet metal parts. Metal sheets are commonly used in photovoltaic modules, and during the processing of metal sheets, stamping equipment is usually used to stamp them.

[0004] In stamping production, to achieve simultaneous processing of multiple workpieces, it is often necessary to install multiple upper dies on the equipment. The current method of fixing the upper dies with bolts has a significant efficiency bottleneck. Every time a set of upper dies is replaced, the operator must tighten or loosen a large number of bolts one by one. The cumbersome bolt operation process seriously prolongs the die replacement time, directly affecting equipment utilization and production efficiency, and impacting production flexibility. Because the replacement is time-consuming and labor-intensive, it is not conducive to achieving rapid die changeover in small-batch, multi-variety production scenarios, reducing the response speed and flexibility of the production line. The repetitive bolt tightening / loosening work increases the physical burden on operators and the potential risk of fatigue. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Refer to Figures 1-4This utility model provides a technical solution: a multi-station stamping device for metal sheets, including a worktable 1. Support columns 19 are fixedly installed at the bottom of the worktable 1, with four sets of support columns 19 arranged in an array. A placement groove 2 is opened at the top of the worktable 1, and a lower pressing die 3 is placed on the inner wall of the placement groove 2. A mounting frame 4 is fixedly installed at the top of the worktable 1. A lifting plate 7 is installed on the inner wall of the mounting frame 4 via a lifting mechanism. The lifting mechanism includes an electric push rod 5 fixedly installed on the inner wall of the mounting frame 4. A push plate 6 is fixedly installed at the output end of the electric push rod 5. The bottom of the push plate 6 and the top of the lifting plate 7 are fixedly installed to facilitate lifting and lowering the lifting plate 7. An upper pressing die 11 is installed on one side of the lifting plate 7 via a positioning mechanism. The positioning mechanism includes a positioning groove 8 opened on one side of the lifting plate 7. A positioning block 9 is slidably installed on the inner wall of the positioning groove 8, and a mounting groove 10 is opened on one side of the positioning block 9. The bottom of the positioning block 9 and the top of the upper mold 11 are fixedly installed. The number of positioning grooves 8, positioning blocks 9, mounting grooves 10 and upper molds 11 are multiple and arranged in an array, which facilitates the positioning of the upper mold 11 and makes the installation of the upper mold 11 more accurate. One side of the lifting plate 7 is equipped with a mounting column 15 through a moving mechanism. The moving mechanism includes a motor 12 fixedly installed on one side of the lifting plate 7. A lead screw 13 is fixedly installed at the output end of the motor 12. A moving plate 14 is threaded on the surface of the lead screw 13. One side of the moving plate 14 and one end of the mounting column 15 are fixedly installed. The number of moving plates 14 and mounting columns 15 are multiple and arranged in an array, which facilitates the movement of multiple sets of mounting columns 15. A sliding groove 18 is opened inside the lifting plate 7. The inner wall of the sliding groove 18 fits against the surface of the moving plate 14 to limit the movement of the moving plate 14 and make the movement of the moving plate 14 more stable.

[0022] Specifically, the inner wall of the mounting frame 4 is provided with a limiting mechanism, which includes a limiting groove 16 formed in the inner wall of the mounting frame 4. A limiting block 17 is slidably installed on the inner wall of the limiting groove 16. One side of the limiting block 17 and one side of the lifting plate 7 are fixedly installed to limit the lifting plate 7, making the lifting of the lifting plate 7 more stable. By installing multiple metal plates on the top of the workbench 1 and above the three lower dies 3, the lifting mechanism drives multiple sets of upper dies 11 to descend. Multiple metal plates can be stamped by the cooperation of multiple lower dies 3 and multiple upper dies 11, thus realizing multi-station stamping. Multiple sets of lower dies 3 can be slid out and new ones can be installed. The lower die 3 is placed on the inner wall of the placement groove 2 to complete the positioning and installation of the lower die 3. The moving mechanism drives the multiple sets of mounting columns 15 to move, so that the multiple sets of mounting columns 15 leave the inner wall of the multiple sets of mounting grooves 10, and the multiple sets of upper dies 11 can be slid off. The positioning mechanism can position the multiple sets of new upper dies 11. The moving mechanism drives the multiple sets of mounting columns 15 to insert into the inner wall of the mounting groove 10, so that the multiple sets of upper dies 11 can be limited and installed. This eliminates the need to install and remove bolts one by one, and achieves the purpose of easy replacement of upper dies 11. It can stamp metal plates of different shapes. The structure is simple and easy to use.

[0023] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0024] In use: When using this multi-station stamping device for metal sheets, multiple metal sheets are installed on the top of the worktable 1, above the three lower dies 3. The electric push rod 5 drives the push plate 6 to descend, the push plate 6 drives the lifting plate 7 to descend, and the lifting plate 7 drives multiple sets of upper dies 11 to descend. Multiple lower dies 3 and multiple upper dies 11 work together to stamp multiple metal sheets, thus achieving multi-station stamping. When stamping metal sheets of different shapes is required, multiple sets of lower dies 3 are slid out, and a new lower die 3 is placed on the inner wall of the placement slot 2 to complete the positioning and installation of the lower die 3. The motor 12 drives the lead screw 13 to rotate, and the lead screw 13 drives... Multiple sets of movable plates 14 move, driving multiple sets of mounting columns 15 to move, causing the mounting columns 15 to leave the inner wall of the mounting grooves 10, thus releasing the limiting installation of multiple sets of positioning blocks 9. This allows multiple sets of upper pressing dies 11 to be slidably removed. Then, the positioning blocks 9 on the top of multiple sets of new upper pressing dies 11 are inserted into the inner wall of the positioning groove 8 to position the multiple sets of upper pressing dies 11. The motor 12 drives the multiple sets of mounting columns 15 to be inserted into the inner wall of the mounting groove 10 to limit the installation of the multiple sets of upper pressing dies 11. This eliminates the need to install and remove bolts one by one, making it easy to replace the upper pressing dies 11. This allows for stamping of metal plates of different shapes, with a simple structure and easy use.
