Description

Technical Field

[0001] This application relates to the field of sheet metal shearing technology, and for example to a sheet metal shearing device. Background Technology

[0002] A related technology (publication number: CN221158797U) discloses a positioning component for sheet metal shearing, including a cutting table. A conveying component is fixedly installed on the top of the cutting table. The conveying component includes a mounting groove formed on the top of the cutting table. An electric slide rail is fixedly installed inside the mounting groove. A track block is movably installed on the top of the electric slide rail. A C-shaped plate is fixedly installed on the top of the track block. A mounting plate is fixedly installed on one side of the C-shaped plate. A drive motor is fixedly installed on the top of the mounting plate. A movable rotating shaft is fixedly installed on one side of the drive motor. The movable rotating shaft extends into the interior of the C-shaped plate. A double-acting screw is fixedly installed at one end of the movable rotating shaft. A positioning nut is movably installed on the outside of the double-acting screw. C-shaped fixing plates are fixedly installed on the top of the two positioning nuts, and a pressing component is fixedly installed inside the two C-shaped fixing plates.

[0003] In implementing the above embodiments, at least the following problems were found in the related technology:

[0004] The positioning assembly for sheet metal shearing uses two pressing components to clamp and fix the sheet metal on both sides. The distance between the two pressing components is adjusted by controlling the drive motor, allowing for the clamping and fixing of sheets of different widths. The position of the two pressing components is synchronously adjusted by controlling the operation of an electric slide rail, thus moving the sheet metal to the shearing station for cutting. However, when the sheet metal is long, the electric slide rail needs a longer travel range to completely transport the sheet metal to the cutting position, resulting in a larger device size and a larger space requirement.

[0017] The sheet metal shearing device provided in this disclosure can achieve the following technical effects:

[0018] This disclosure provides a sheet metal shearing device, including a support frame, a linear slide, a first L-shaped plate, an electric push rod, a second L-shaped plate, a cylinder with a guide rod, a hydraulic cylinder, and a cutter. The support frame supports the entire device. The support frame includes a first support plate and a second support plate parallel to each other in their respective planes. Along the height direction of the support frame, the first support plate is located below the second support plate. The first and second support plates respectively support and install relevant components of the device. The linear slide is installed on the top surface of the first support plate along the width direction of the support frame and on both sides of the top surface of the first support plate along the length direction of the support frame. Both linear slides are used to move along the width direction of the support frame. The first L-shaped plates are respectively installed on the moving ends of the two linear slides, and under the drive of the two linear slides, they move along the width direction of the support frame. The electric push rods are respectively installed on the two first L-shaped plates along the length direction of the support frame, with their moving ends opposite to each other. Both electric push rods are used to move along the length direction of the support frame. The second L-shaped plates are respectively installed on the moving ends of the electric push rods on both sides, and move along the length of the support frame under the drive of the electric push rods. Guide rod cylinders are respectively installed on the vertical walls of the second L-shaped plates on both sides along the height of the support frame, with the moving ends of the two guide rod cylinders facing the horizontal walls of the second L-shaped plates on both sides, respectively, for pressing the two sides of the plate. A hydraulic cylinder is installed on the second support plate along the height of the support frame, with the moving end of the hydraulic cylinder facing the first support plate, for providing shearing force. A cutter is installed on the moving end of the hydraulic cylinder and moves along the height of the support frame under the drive of the hydraulic cylinder, for shearing the plate. The horizontal walls of the second L-shaped plates on both sides are located between the vertical walls of the second L-shaped plates on both sides; the horizontal walls of the second L-shaped plates on both sides support the plate, and the vertical walls of the second L-shaped plates on both sides clamp the plate.

[0019] In operation, controlling the electric push rods on both sides moves the second L-shaped plates on both sides along the length of the support frame, allowing plates of different widths to be placed on the horizontal walls of the second L-shaped plates. Simultaneously, the vertical walls of the second L-shaped plates clamp and position the plates. Then, extending the moving end of the left-side guide rod cylinder presses and secures the plates. Next, controlling the left-side linear slide moves the left-side first L-shaped plate along the width of the support frame, performing a primary conveying of the plates. When the left-side linear slide reaches its maximum stroke, retracting the moving end of the left-side guide rod cylinder and extending the moving end of the right-side guide rod cylinder presses and secures the plates again. Finally, controlling the right-side linear slide moves the right-side first L-shaped plate along the width of the support frame, performing a secondary conveying of the plates, while simultaneously resetting the moving end of the left-side linear slide. Once the right linear slide reaches its maximum stroke, the moving end of the right guide rod cylinder retracts, while the moving end of the left guide rod cylinder extends, thus pressing and fixing the sheet metal again before resuming transport. Therefore, by alternately controlling the linear slides and thumb cylinders on both sides, sheets of different lengths can be continuously transported without being affected by the sheet metal length, reducing the space occupied by the device.

The support frame 1 supports the entire device. The support frame 1 includes a first support plate 01 and a second support plate 02 that are parallel to each other in their respective planes. Along the height direction of the support frame 1, the first support plate 01 is located below the second support plate 02. The first support plate 01 and the second support plate 02 are respectively used to support and install relevant components of the device. The linear slide table 2 is installed on the top surface of the first support plate 01 along the width direction of the support frame 1, and is located on both sides of the top surface of the first support plate 01 along the length direction of the support frame 1. Both linear slide tables 2 are used to realize the function of moving along the width direction of the support frame 1. The first L-shaped plates 3 are respectively installed on the moving ends of the two linear slide tables 2, and under the drive of the two linear slide tables 2, they move along the width direction of the support frame 1. Electric push rods 4 are installed on the first L-shaped plates 3 on both sides along the length of the support frame 1. The moving ends of the electric push rods 4 on both sides are relatively distributed, and both electric push rods 4 are used to move along the length of the support frame 1. Second L-shaped plates 5 are installed on the moving ends of the electric push rods 4 on both sides, and move along the length of the support frame 1 under the drive of the electric push rods 4. Guide rod cylinders 6 are installed on the vertical walls of the second L-shaped plates 5 on both sides along the height of the support frame 1. The moving ends of the two guide rod cylinders 6 face the horizontal walls of the second L-shaped plates 5 on both sides, and are used to press the two sides of the plate. Hydraulic cylinders 7 are installed on the second support plate 02 along the height of the support frame 1. The moving end of the hydraulic cylinder 7 faces the first support plate 01, and is used to provide shearing force. Cutter 8 is installed on the moving end of the hydraulic cylinder 7 and moves along the height of the support frame 1 under the drive of the hydraulic cylinder 7, and is used to shear the plate. The horizontal walls of the second L-shaped plates 5 on both sides are located between the vertical walls of the two L-shaped plates. The horizontal walls of the second L-shaped plates 5 on both sides are used to support the plates, and the vertical walls of the second L-shaped plates 5 on both sides are used to clamp the plates.

[0037] This embodiment of the invention provides a sheet metal shearing device. Controlling the electric push rods 4 on both sides causes the second L-shaped plates 5 on both sides to move along the length of the support frame 1, allowing sheets of different widths to be placed on the horizontal walls of the second L-shaped plates 5. Simultaneously, the vertical walls of the second L-shaped plates 5 clamp and position the sheets. Then, controlling the extension of the moving end of the left-side guide rod cylinder 6 presses and fixes the sheet metal. At this time, controlling the left-side linear slide 2 causes the left-side first L-shaped plate 3 to move along the width of the support frame 1, thus conveying the sheet metal once. When the left-side linear slide 2 reaches its maximum stroke, controlling the retraction of the moving end of the left-side guide rod cylinder 6 and controlling the extension of the moving end of the right-side guide rod cylinder 6 presses and fixes the sheet metal again. At this time, controlling the right-side linear slide 2 causes the right-side first L-shaped plate 3 to move along the width of the support frame 1, thus conveying the sheet metal a second time, while simultaneously controlling the reset of the moving end of the left-side linear slide 2. When the right linear slide 2 reaches its maximum stroke, the moving end of the right guide rod cylinder 6 is retracted, and the moving end of the left guide rod cylinder 6 is extended, thus pressing and fixing the sheet metal again, and then conveying it again. Therefore, by alternately controlling the operation of the linear slides 2 on both sides and the thumb cylinder, sheets of different lengths can be continuously conveyed without being affected by the length of the sheet metal, reducing the space occupied by the device.
