Description

Technical Field

[0001] This utility model relates to the field of metal cutting technology, specifically to a double-cylinder shear for metal cutting. Background Technology

[0002] With the advancement of global industrialization, the demand for recycling metal waste (such as scrap steel, auto parts, and construction waste) is increasing daily. Metal dismantling and shearing, as a crucial step in waste processing, requires efficient and precise equipment to crush and separate materials. For example, in the dismantling of end-of-life vehicles, high-strength car body frames need to be sheared into reusable metal blocks, but traditional equipment is inefficient when processing high-hardness, large-sized metals.

[0003] Traditional metal shearing equipment has evolved from mechanical lever type, single-cylinder hydraulic type to multi-cylinder hydraulic type. It achieves shearing through the mechanical lever principle. The structure is simple but the shearing force is limited. It is only suitable for thin metal materials and has high energy consumption and noise. Therefore, a double-cylinder shear for metal dismantling and shearing is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a double-cylinder shear for metal cutting, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a double-cylinder shear for metal disassembly and cutting, comprising a connecting metal plate, on which a disassembly and cutting assembly is disposed, the disassembly and cutting assembly comprising two first rotating shafts rotatably connected to the connecting metal plate, the two first rotating shafts being symmetrically arranged, a drive cylinder being rotatably connected to the outer side of each of the two first rotating shafts, and a second rotating shaft being rotatably connected to the other end of each of the two drive cylinders, a triangular drive plate being rotatably connected to the outer side of the second rotating shaft near the middle position, a third rotating shaft being rotatably connected to the triangular drive plate, and the third rotating shaft being rotatably connected to the connecting metal plate.

[0006] As a further improvement to this technical solution, a limiting ring is fixedly connected to the outer side of the third rotating shaft, and the limiting ring is used to limit the position of the triangular drive plate.

[0007] As a further improvement to this technical solution, a plurality of snap-fit ​​posts are provided on one side of the triangular drive plate, and an arc-shaped scissor blade is fixedly installed on the plurality of snap-fit ​​posts.

[0008] As a further improvement to this technical solution, a circular connecting plate is fixedly connected to the center of the top side of the connecting metal plate, and a rotating ring is fixedly connected to the center of the top side of the circular connecting plate. A connecting column is rotatably connected inside the rotating ring, and the connecting column is used for equipment connection.

[0009] As a further improvement to this technical solution, two reinforcing ribs are fixedly connected to both sides of the connecting metal plate, and the top side of the reinforcing ribs is fixedly connected to the bottom side of the circular connecting disc.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] In a double-cylinder shear for metal cutting, two drive cylinders in the cutting assembly drive two triangular drive plates to rotate on the connecting metal plate. When the two triangular drive plates rotate in opposite directions, the arc-shaped shear blades on the two triangular drive plates clamp or cut the metal, thereby solving the defects caused by a single drive cylinder, improving the efficiency of metal cutting, and solving the problems of high energy consumption and high noise.

[0018] Please see Figures 1-2 As shown, this embodiment provides a double-cylinder shear for metal dismantling and cutting, including a connecting metal plate 1. A dismantling and cutting assembly 2 is mounted on the connecting metal plate 1. The dismantling and cutting assembly 2 facilitates metal dismantling and cutting by workers, thereby increasing work efficiency. The dismantling and cutting assembly 2 includes two first rotating shafts 21, which are rotatably connected to the connecting metal plate 1. The two first rotating shafts 21 are symmetrically arranged. A drive cylinder 22 is rotatably connected to the outer side of each of the two first rotating shafts 21. The two drive cylinders 22 rotate on the connecting metal plate 1 via the two first rotating shafts 21. A second rotating shaft 23 is rotatably connected to the other end of each of the two drive cylinders 22. A triangular drive plate 24 is rotatably connected to the outer side of the second rotating shaft 23 near the center. The two second rotating shafts 23 cause the two drive cylinders 22 to drive two triangular drive plates respectively. The rotating plate 24 drives the two triangular drive plates 24 to rotate in opposite directions, thereby clamping or shearing the metal. A third rotating shaft 25 is rotatably connected to the triangular drive plate 24 and is rotatably connected to the connecting metal plate 1. The two third rotating shafts 25 ensure that the two triangular drive plates 24 rotate stably on the connecting metal plate 1. A limiting ring 26 is fixedly connected to the outer side of the third rotating shaft 25. The limiting ring 26 is used to limit the triangular drive plate 24 and prevent it from shifting when rotating on the connecting metal plate 1. Multiple locking posts 27 are provided on one side of the triangular drive plate 24. Arc-shaped shear blades 28 are fixedly installed on the multiple locking posts 27. The multiple locking posts 27 allow the arc-shaped shear blades 28 to be detachably installed, making it convenient to replace the arc-shaped shear blades 28.

[0019] Please see Figure 1 As shown, a circular connecting plate 4 is fixedly connected to the center of the top side of the connecting metal plate 1. A rotating ring 5 is fixedly connected to the center of the top side of the circular connecting plate 4. A connecting column 6 is rotatably connected inside the rotating ring 5. The connecting column 6 is used for equipment connection. The circular connecting plate 4, rotating ring 5 and connecting column 6 enable the double cylinder shear to rotate, increasing the flexibility of the double cylinder shear. Two reinforcing ribs 3 are fixedly connected to both sides of the connecting metal plate 1. The top side of the reinforcing rib 3 is fixedly connected to the bottom side of the circular connecting plate 4. The multiple reinforcing ribs 3 can strengthen the connection between the connecting metal plate 1 and the circular connecting plate 4.

[0020] In this embodiment, the double-cylinder shear for metal cutting is fixedly connected to the equipment. Two drive cylinders 22 drive two triangular drive plates 24 to rotate on the connecting metal plate 1. When the two triangular drive plates 24 rotate, two limiting rings 26 limit the two triangular drive plates 24 to prevent them from shifting when rotating on the connecting metal plate 1. When the two triangular drive plates 24 rotate towards each other, the arc-shaped scissor blades 28 on the two triangular drive plates 24 clamp or cut the metal. Multiple locking posts 27 on the triangular drive plates 24 facilitate the disassembly of the arc-shaped scissor blades 28. The circular connecting plate 4, rotating ring 5 and connecting post 6 enable the double-cylinder shear to rotate, increasing the flexibility of the double-cylinder shear.
