Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically a safe feeding shearing machine. Background Technology

[0002] Traditional shearing machines primarily rely on manual feeding, which depends heavily on the operator's skills and experience. However, manual feeding has the following drawbacks:

[0003] Operators need to have certain skills and experience to ensure the stability and accuracy of the board during the feeding process. For operators who are not skilled enough, it is easy to cause the board cut to be tilted, affecting the cutting angle of the board.

[0004] During manual feeding, burrs on the side of the sheet can easily pierce the operator's gloves, causing cuts or more serious injuries. In addition, when the operator's hands are close to the blade, a shearing accident can easily occur if the operator is not careful. Therefore, a safe feeding shearing machine is needed to solve the above problems. Utility Model Content

[0008] The guide rail is located at the top of the frame and is symmetrically distributed about the center point of the frame. One end of the guide rail extends towards the front end of the frame and is suspended in the air. The outer surface of the guide rail is slidably connected to a front baffle and a rear baffle, and the front baffle and the rear baffle are connected to the guide rail by a slider.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a safe feeding shearing machine, comprising:

[0020] The frame 1 is the main support structure of the shearing machine. A fixed bracket 2 is set at the top of the frame 1. An upper shearing blade 3 and a lower shearing blade 17 are set inside the fixed bracket 2. The lower shearing blade 17 is suspended on the inner surface of the fixed bracket 2.

[0021] The guide rail 4 is located at the top of the frame 1 and is symmetrically distributed about the center point of the frame 1. One end of the guide rail 4 extends towards the front end of the frame 1 and is suspended in the air. The outer surface of the guide rail 4 is slidably connected to the front baffle 5 and the rear baffle 7, and the front baffle 5 and the rear baffle 7 are provided with the guide rail 4 in sliding engagement with the slider 15. The top of the front baffle 5 is symmetrically provided with concave handles 8, and the inner surface of the front baffle 5 is movably connected with a movable shaft 13. The outer surface of the movable shaft 13 is equipped with a pressure plate 12, and the outer surface of the pressure plate 12 is provided with a rod-type handle 11. A torsion spring 16 is provided between the movable shaft 13 and the front baffle 5.

[0022] The pressure plate 12 forms a rotating structure with the front baffle 5 through the movable shaft 13 and the rod handle 11. The pressure plate 12 compacts the sheet material on the surface of the front baffle 5 and the rear baffle 7 by rotating, ensuring that the sheet material will not shift during the adjustment of the distance between the front baffle 5 and the rear baffle 7, and that the sheet material will not shift during the shearing process, thereby improving the stability of the shearing process.

[0023] The rear baffle 7 has an internal movable groove 14. The bottom surface of the movable groove 14 is higher than the top surface of the lower shear blade 17. A movable bracket 6 is movably connected inside the rear baffle 7. One end of the movable bracket 6 is fixedly connected to the front baffle 5. The bottom surface of the front baffle 5 is the same as the bottom surface of the movable groove 14. The top surface of the movable bracket 6 is lower than the bottom surface of the lower shear blade 17. The movable bracket 6 is located between the front baffle 5 and the rear baffle 7 in an interlocking manner. The front baffle 5, together with the movable groove 14 of the rear baffle 7, supports the sheet metal and facilitates the adjustment of the distance between the front baffle 5 and the rear baffle 7.

[0024] A lead screw 10 is movably connected to the outer surface of one end of the movable bracket 6. The lead screw 10 is threadedly connected to the rear baffle 7, and the other end of the lead screw 10 is movably connected to the front baffle 5. The lead screw 10 and the rear baffle 7 are threadedly driven and can slide horizontally along the guide rail 4 and the outer surface of the movable bracket 6. On this basis, the rear baffle 7 can also move synchronously with the front baffle 5 and the movable bracket 6, increasing the flexibility of adjustment.

[0025] One end of the lead screw 10 passes through the interior of the front baffle 5, and a handle 9 is provided on the outer surface of one end of the lead screw 10. The height of the lead screw 10 is lower than the horizontal height of the inner surface of the front baffle 5 and the rear baffle 7. The lead screw 10 is rotated by the handle 9 to control the distance between the front baffle 5 and the rear baffle 7 by means of threaded transmission, so as to be able to fix plates of different lengths.

[0026] Working principle: The front baffle 5 and the rear baffle 7 are initially in a close-fitting state. One end of the plate is passed through the movable groove 14 and horizontally fitted to the inner surface of the front baffle 5. At the same time, the control lever handle 11 rotates the pressure plate 12. The pressure plate 12 rotates around the movable shaft 13 as the center point. The pressure plate 12 presses and fixes the plate surface by an angle. At the same time, the concave handle 8 and the lever handle 11 are held to maintain the pressure plate 12 and the plate in a compacted state. Then, according to the length of the plate, the rotating handle 9 is rotated to adjust the horizontal position of the rear baffle 7 so that the distance between the front baffle 5 and the rear baffle 7 is greater than half the length of the plate. The leverage force is used to improve the stability of the support. Then, both hands are used to grasp the concave handle 8 and the rotating handle 9 to push the rear baffle 7 and the plate. The front baffle 5 slides forward along the guide rail 4. At this time, the movable bracket 6 is located at the bottom of the lower shearing blade 17, while the plate supported between the movable groove 14 and the front baffle 5 is located between the upper shearing blade 3 and the lower shearing blade 17. The upper shearing blade 3 is cut off by the lower shearing blade 17 through the up-and-down extension and retraction of the hydraulic cylinder. The cut plate falls to the movable bracket 6 for support. The cut plate is taken out from the other end of the fixed bracket 2. Then the lever handle 11 is released, and the lever handle 11 and the pressure plate 12 are reset under the action of the torsion spring 16. The above operation is repeated to adjust the position of the plate again. This not only ensures the flatness of the plate by using a close fit, but also ensures the safety of the operator during the cutting process by preventing contact between the operator and the plate.
