Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a shearing machine with a sheet metal limiting structure. Background Technology

[0002] A shearing machine is a machine that uses one blade to reciprocate linearly relative to another blade to shear sheet metal. It utilizes a moving upper blade and a fixed lower blade, with a suitable blade gap, to apply shearing force to metal sheets of various thicknesses, causing the sheet metal to break and separate to the required dimensions. Shearing machines belong to the category of forging and pressing machinery, primarily used in the metal processing industry. Their products are widely used in aerospace, light industry, metallurgy, chemical industry, construction, shipbuilding, automotive, power, electrical appliances, decoration, and other industries, providing the necessary specialized machinery and complete sets of equipment.

[0003] In Chinese utility model patents, such as CN218503442U, an environmentally friendly sheet metal shearing machine with a limiting function is disclosed. It has the advantages of being able to adjust the position of the limiting columns on both sides according to the size of the sheet metal, which facilitates the positioning and limiting of the sheet metal, and the adjustment is convenient, quick and stable.

[0004] The above-mentioned technology can limit the two sides of the board during use, thereby ensuring the stability of the board during processing. However, the top surface of the board is not limited and fixed during processing. When the board is subjected to the force of the upper and lower cutting blades, it is prone to vibration, resulting in burrs and unevenness at the cutting edge. In view of this, this application proposes a shearing machine with a board limiting structure. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a shearing machine with a plate limiting structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A shearing machine with a plate limiting structure includes a worktable. A first gantry frame is fixedly installed on the top surface of the worktable. Multiple second electric telescopic rods are symmetrically installed on the bottom surface of the first gantry frame. A sliding seat is installed at the bottom end of the multiple second electric telescopic rods. An upper cutter is fixedly installed on the bottom surface of the sliding seat. A connecting plate is fixedly installed on the side of the sliding seat. An assembly seat is slidably connected to the bottom surface of the connecting plate. The connecting plate drives the assembly seat to slide up and down through an adjustment mechanism. Two threaded sleeves are symmetrically slidably connected to the bottom surface of the assembly seat. The assembly seat drives the two threaded sleeves to slide towards each other through a driving mechanism. A spring telescopic rod is fixedly installed on the bottom surface of each threaded sleeve. A pressure plate is fixedly installed on the bottom surface of each spring telescopic rod.

[0008] Preferably, the driving mechanism includes a double-ended screw, which is rotatably connected to the side wall of the mounting base, and two threaded sleeves are symmetrically threaded onto the double-ended screw. A rocker arm is rotatably connected to one side of the mounting base, and one end of the double-ended screw passes through the mounting base and is connected to the rocker arm.

[0009] Preferably, the adjusting mechanism includes two threaded rods, which are symmetrically distributed at both ends of the top surface of the connecting plate. Each threaded rod is threadedly connected to the connecting plate, and the other end of each threaded rod passes through the connecting plate and is rotatably connected to the mounting base.

[0010] Preferably, a plurality of second gantry frames are symmetrically installed on the top surface of the workbench, and a first electric telescopic rod is fixedly installed on both inner sides of each second gantry frame. The other ends of the plurality of first electric telescopic rods located on the same side are all equipped with a side plate.

[0011] Preferably, T-shaped blocks are fixedly installed at both ends of the sliding seat, and T-shaped grooves are opened on both inner sides of the first gantry frame, and each T-shaped block is slidably connected in the corresponding T-shaped groove.

[0012] Preferably, the top surface of the workbench is symmetrically equipped with multiple support legs, and each threaded rod has a knob installed at its top.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model, through devices such as a second electric telescopic rod, a sliding seat, an upper cutter, a spring telescopic rod, and a pressure plate, realizes that when the second electric telescopic rod drives the sliding seat to slide and the upper cutter cuts the plate, it will simultaneously adjust the mounting seat to slide downward, and the spring telescopic rod will drive the pressure plate to squeeze the top of the plate, so that the plate is tightly attached to the worktable, reducing vibration during cutting, thereby reducing the problems of burrs and unevenness on the cutting edge.

[0015] 2. This utility model, through devices such as a double-ended screw, a threaded rod, and a threaded sleeve, enables the height of the mounting base to be adjusted by turning the threaded rod, thereby adjusting the squeezing force of the pressure plate on the plate. This facilitates the adaptation to plates of different materials and thicknesses. Furthermore, by turning the double-ended screw, the threaded sleeve can be driven to slide in opposite directions, allowing the two pressure plates to adapt to plates of different sizes, thus improving the practicality of the device.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] This utility model provides a technical solution: such as Figure 1-3 As shown, a shearing machine with a sheet metal limiting structure includes a worktable 1. A first gantry frame 3 is fixedly installed on the top surface of the worktable 1. Multiple second electric telescopic rods 8 are symmetrically installed on the bottom surface of the first gantry frame 3. A sliding seat 9 is installed at the bottom end of the multiple second electric telescopic rods 8. An upper cutter 12 is fixedly installed on the bottom surface of the sliding seat 9. It should be noted that a lower cutter is also provided on the worktable 1 for cooperating with the upper cutter 12 to process the sheet metal. A connecting plate 10 is fixedly installed on the side of the sliding seat 9. An assembly seat 14 is slidably connected to the bottom surface of the connecting plate 10. The connecting plate 10 can be adjusted... The joint mechanism drives the assembly base 14 to slide up and down, which facilitates the adjustment of the height of the assembly base 14. This changes the force of the spring telescopic rod 17, which drives the pressure plate 18 to limit and fix plates of different materials and thicknesses. The bottom surface of the assembly base 14 is symmetrically slidably connected to two threaded sleeves 16. The assembly base 14 drives the two threaded sleeves 16 to slide towards each other through the drive mechanism. The bottom surface of each threaded sleeve 16 is fixedly installed with a spring telescopic rod 17, and the bottom surface of each spring telescopic rod 17 is fixedly installed with a pressure plate 18. Through the threaded sleeves 16 and the drive mechanism, the two pressure plates 18 can be adapted to limit plates of different sizes.

[0022] Furthermore, the driving mechanism includes a double-ended screw 15, which is rotatably connected to the side wall of the mounting base 14. Two threaded sleeves 16 are symmetrically threaded onto the double-ended screw 15. A rocker arm 19 is rotatably connected to one end of the mounting base 14, and one end of the double-ended screw 15 passes through the mounting base 14 and is connected to the rocker arm 19. The double-ended screw 15 is rotated by manually rotating the rocker arm 19. It should be noted that a cavity is provided inside the mounting base 14, and a through groove is provided on the bottom surface of the mounting base 14. The threaded sleeves 16 are movably connected in the cavity and slidably connected to the through groove, so that the threaded sleeves 16 cannot rotate and can only slide linearly.

[0023] Furthermore, the adjustment mechanism includes two threaded rods 13, which are symmetrically distributed at both ends of the top surface of the connecting plate 10. Each threaded rod 13 is threadedly connected to the connecting plate 10, and the other end of each threaded rod 13 passes through the connecting plate 10 and is rotatably connected to the mounting base 14. By turning the threaded rods 13 at both ends, the mounting base 14 can be adjusted to slide up and down.

[0024] Furthermore, multiple second gantry frames 4 are symmetrically installed on the top surface of the workbench 1. Each second gantry frame 4 has a first electric telescopic rod 5 fixedly installed on both inner sides. The other ends of the multiple first electric telescopic rods 5 located on the same side are all equipped with side plates 6. The side plates 6 limit the two ends of the board and can adapt to boards of different sizes.

[0025] Furthermore, T-shaped blocks 11 are fixedly installed at both ends of the sliding seat 9, and T-shaped grooves 7 are opened on both inner sides of the first gantry frame 3. Each T-shaped block 11 is slidably connected in the corresponding T-shaped groove 7 to maintain the sliding stability of the sliding seat 9.

[0026] Furthermore, multiple support legs 2 are symmetrically installed on the top surface of the workbench 1, and a knob is installed at the top of each threaded rod 13. The knob is manually operated to drive the threaded rod 13 to rotate.

[0027] This utility model provides a shearing machine with a sheet metal limiting structure. The specific working principle is as follows: First, the operator places the sheet metal on the top surface of the workbench 1. Then, by activating multiple first electric telescopic rods 5 on both sides, the side plates 6 on both sides slide simultaneously. The position of the side plates 6 can be determined according to the size of the sheet metal, thus limiting the sheet metal during processing and preventing it from shifting. Next, the operator manually pushes the sheet metal to the bottom of the first gantry 3. Then, multiple second electric telescopic rods 8 are activated, causing the sliding seat 9 to slide downwards. The upper cutter 12, in cooperation with the lower cutter installed inside the workbench 1, shears the sheet metal. Simultaneously, as the sliding seat 9 slides downwards... When the plate is in use, the connecting plate 10 can be driven to slide down synchronously, and the pressure plate 18 can be pressed tightly against the plate by the force of the spring telescopic rod 17, thereby limiting the plate from the top surface and reducing the vibration during cutting. This reduces the problems of burrs and unevenness at the cutting edge. For plates of different materials and thicknesses, the position of the mounting base 14 can be adjusted by simultaneously turning the threaded rods 13 at both ends, thereby adjusting the squeezing force of the spring telescopic rod 17 on the plate by the pressure plate 18, improving the practicality of the device. Furthermore, according to the size of the plate, the rocker arm 19 can be turned to drive the double-headed screw 15 to rotate, thereby adjusting the position of the two threaded sleeves 16 so that the two pressure plates 18 can match the plates of different sizes.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
