Description

Technical Field

[0001] This utility model relates to the field of metal sheet processing technology, specifically to a metal sheet punching equipment with waste recycling function. Background Technology

[0002] Metal sheets, as a widely used material, have a flat surface and relatively thin thickness, and are usually made of various metal materials, such as steel, aluminum, copper, and stainless steel. Metal sheets can be manufactured through hot rolling, cold rolling, or other processing techniques, and have different thicknesses, dimensions, and surface treatments. Metal sheet stamping equipment with waste recycling capabilities has significant practical value and significance in terms of resource reuse, cost reduction, and environmental protection. According to CN222094468U, a metal sheet punching device with waste recycling is disclosed. This technology discloses "a metal sheet punching device with waste recycling, including a support frame, a first support block fixedly connected to the upper surface of the support frame, a first motor fixedly connected to the outer wall of the first support block, a gear fixedly connected to the output end of the first motor, a rack meshing with the lower surface of the gear, a scraper fixedly connected to the outer wall of the rack, a lower surface of the rack slidably connected to the inner wall of the support frame, a limit block fixedly connected to the upper surface of the support frame, a rack slidably connected to the inner wall of the limit block, and a punching assembly provided on the upper surface of the support frame". It has the technical effect of "the first motor drives the gear to rotate, thereby driving the rack to slide. When the rack slides, it can drive the scraper to slide. Then, the limit block limits the rack, so the waste can slide to the inner wall of the second storage bin, thereby achieving the effect of waste recycling". The above-mentioned solution mainly targets the recycling of scrap and waste generated during the processing. However, in actual production, workpieces are often cut into multiple finished products from a long raw metal plate through continuous punching. The resulting waste is not scattered scrap, but still maintains a size similar to or even the same as the raw metal plate, resulting in a large space occupation and making it difficult to process through conventional scrap recycling. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a metal sheet punching equipment with waste recycling. After punching, the remaining waste is fed into the shearing unit through the positioning unit to cut the waste metal sheet into regular fragments.

An upper mounting base 235 is mounted on the output end of the second hydraulic cylinder 234. An upper cutter head 236 is fixed to the lower end of the upper mounting base 235.

[0016] In this embodiment, after the metal sheet 3 is punched by the punching unit 22, the remaining waste material continues to be fed into the shearing unit 23 through the positioning unit 21. The upper cutter head 236 on the upper mounting base 235 is driven to descend by the output end of the second hydraulic cylinder 234, so that the upper cutter head 236, together with the lower cutter head 233, can cut the waste metal sheet 3 into fragments, which is convenient for subsequent recycling.

[0017] Specifically, the positioning unit 21 includes a material inlet 211 located in the middle of the upper end of the platform 1, a guide rail 212 fixed on the right side of the top of the platform 1, a slide block 213 slidably mounted on the guide rail 212, a positioning plate 214 fixed at the rear end of the top of the slide block 213, clamps 215 mounted on both sides of the front end of the top of the slide block 213, and a standard cylinder 219 mounted on the right end of the top of the platform 1 for driving the slide block 213.

[0018] In this embodiment, by placing the metal sheet 3 on the slide 213 and positioning it with the positioning plate 214, then fixing it with the clamp 215, and then driving the slide 213 to slide along the guide rail 212 with the standard cylinder 219, the metal sheet 3 on the slide 213 is continuously fed, ensuring the accurate positioning and stable feeding of the metal sheet 3 during the processing, and improving the processing accuracy and efficiency.

[0019] Specifically, the positioning unit 21 also includes an extension frame 216 fixed to the right end of the platform 1. A bearing seat 217 is fixed to the top of the extension frame 216, and a roller 218 is rotatably mounted on the bearing seat 217.

[0020] In this embodiment, the conveyed metal sheet 3 is supported by the roller 218, which reduces the friction of the metal sheet 3 during the conveying process.

[0021] Specifically, the punching unit 22 includes a first base 221 fixed in the middle of the top of the table body 1. A lower die base 222 is fixed inside the lower end of the first base 221. A die 223 is fixed on the top of the lower die base 222. A first hydraulic cylinder 224 is installed on the top of the first base 221. An upper die base 225 is fixed at the output end of the first hydraulic cylinder 224. A die head 226 is fixed at the bottom of the upper die base 225.

[0022] In this embodiment, when the metal sheet 3 is fed into the punching unit 22 through the positioning unit 21, the upper die holder 225 is driven by the first hydraulic cylinder 224 to drive the die head 226 to descend, so that the die head 226 cooperates with the mold 223 to punch the metal sheet 3.

[0023] Specifically, the shearing unit 23 also includes a hopper 237 fixed to the left end of the lower mounting base 232.

[0024] In this embodiment, the waste material cut by the shearing unit 23 can slide into the waste bin 5 through the hopper 237.

[0025] Specifically, the finished parts box 4 is placed inside the platform 1 and is located directly below the material inlet 211, and the waste material box 5 is placed on the left side of the platform 1.

[0026] In this embodiment, the workpieces punched by the metal sheet 3 by the punching unit 22 fall into the finished product box 4 through the material outlet 211 for collection. The remaining waste material of the metal sheet 3 is cut into fragments by the shearing unit 23 and falls into the waste box 5 for recycling, thus realizing the automatic separation and collection of workpieces and waste.

[0027] The working principle and usage process of this utility model are as follows: First, the metal plate 3 is placed on the slide 213 and positioned by the positioning plate 214, then fixed by the clamp 215, and then the slide 213 is driven to slide along the guide rail 212 by the standard cylinder 219 to realize continuous feeding of the metal plate 3 on the slide 213; at the same time, the conveyed metal plate 3 is supported by the roller 218, and the friction of the metal plate 3 during the conveying process is reduced. Then, when the metal sheet 3 is fed into the punching unit 22 through the positioning unit 21, the upper die base 225 is driven by the first hydraulic cylinder 224 to drive the die head 226 to descend, so that the die head 226 cooperates with the mold 223 to punch the metal sheet 3; the punched workpiece falls into the finished part box 4 through the material port 211 for collection. Finally, the remaining scrap after punching continues to be fed into the shearing unit 23 through the positioning unit 21. The upper cutter head 236 on the upper mounting base 235 is driven to descend through the output end of the second hydraulic cylinder 234, so that the upper cutter head 236, together with the lower cutter head 233, can cut the scrap metal sheet 3 into fragments; the scrap fragments slide down into the scrap bin 5 through the hopper 237 for recycling.
