[0001] This application relates to the technical field of sheet metal shearing, and particularly relates to a shearing mechanism for a plate shearing machine. Background Art

[0002] A plate shearing machine is a mechanical device used for cutting metal sheets and is commonly found in the metal processing industry. Its working principle is based on mechanical cutting, where a tool is used to shear the metal sheet to achieve the required size and shape. A plate shearing machine usually consists of a frame, a tool, a transmission system, a control system, and other components.

[0003] In the prior art, after the operator loads the sheet, the upper blade is pressed down by a hydraulic press and acts on the pre-shearing position of the sheet. Then, it acts together with the lower fixed blade to cut off a part of the sheet, and this process repeats.

[0004] Regarding the above related technology, the inventor believes that during the above operation process, after the operator places the sheet on the shearing table, it is necessary to adjust it as the sheet is continuously sheared. In this process, it is necessary to ensure that the pushing distance is the same each time, which requires high skills from the operator, is difficult to operate, has a high labor intensity, and is accompanied by certain risks.

[0021] The following will further elaborate on this application in conjunction with the attached Figures 1 - 3 drawings.

[0022] An embodiment of this application discloses a shearing mechanism for a plate shearing machine. Referring to Figures 1 - 3 , a shearing mechanism for a plate shearing machine includes a shearing box 1. A ramp groove 2 for automatically pushing materials by the gravity of the plate is installed on the upper part of the shearing box 1. Two first limiting mechanisms 3 for limiting the sides of the plate are symmetrically installed on the surface of the ramp groove 2. And a second limiting mechanism 4 for controlling the shearing length of the plate each time is installed at the end of the ramp groove 2 on one side of the shearing box 1. And a shearing mechanism 5 for shearing the plate is also installed at the end of the upper ramp groove 2 of the shearing box 1; when the plate is placed on the ramp groove 2, when the end of the plate is sheared off and falls, the plate will move downward along the ramp groove 2 under the action of gravity until the end is re-limited by the second limiting mechanism 4, and then shearing is performed again. In this way, automatic feeding can be realized and the feeding distance each time can be ensured to be the same, greatly saving manpower and improving safety.

[0023] Referring to Figure 3 , the first limiting mechanism 3 includes a first sliding component 301 installed on the ramp groove 2, which mainly includes a screw. A slider is threadedly installed on the screw. Two first chutes are symmetrically opened on the upper part of the ramp groove 2. The screw on the first sliding component 301 is rotatably installed in the first chute, and the corresponding slider is slidably installed in the first chute. And this slider is fixedly connected to the first limiting plate 302. A number of balls are movably installed on the surface of the first limiting plate 302; by rotating the screw, the two first limiting plates 302 can approach or move away from each other according to the width of the plate, so that the balls on the first limiting plate 302 are in contact with the side surface of the plate, and can limit the position on the horizontal plane.

[0024] Referring to Figure 3, the second limiting mechanism 4 includes a slide rail 401 fixedly arranged on one side of the shearing box 1 and below the end of the ramp groove 2. There is a certain distance between the slide rail 401 and the ramp groove 2 to ensure that the end of the plate can fall smoothly after being sheared. A second sliding component 402 with the same structure as the first sliding component 301 is installed on the slide rail 401. It mainly includes a screw rod, on which a slider is threadedly installed. A second chute is provided on the slide rail 401. The screw rod on the second sliding component 402 is rotatably installed in the second chute, and the corresponding slider is slidably installed in the second chute, and this slider is fixedly connected to the second limiting plate 403. The end of the plate is abutted and limited by the second limiting plate 403, so that the plate cannot slide down. The distance between the first limiting plate 302 and the lower cutting knife can be adjusted by rotating the screw rod to drive the slider to drive the first limiting plate 302 to move, so as to facilitate adjustment according to the shearing length of the plate, making it more convenient to use.

[0025] Referring to Figures 1 - 2 , a notch groove 6 is provided at the end of the ramp groove 2. The shearing mechanism 5 includes a lower blade 501 fixedly installed in the notch groove 6. The top surface of the lower blade 501 is flush with the ramp surface of the ramp groove 2. A bracket 502 is installed above the lower blade 501 in the upper part of the shearing box 1. Two hydraulic rods 503 are installed on the bracket 502. An upper blade 504 is connected to the output shafts of the two hydraulic rods 503. Guide rods 506 are fixedly arranged on both sides of the upper blade 504. One end of the guide rod 506 is movably installed on the ramp groove 2. A positioning mechanism 505 is connected to the side surface of the upper blade 504. The bottom of the plate is in contact with the blade part of the lower blade 501. The upper blade 504 is driven by the hydraulic rod 503 to move downward, so that the plate is sheared by the shearing force of the upper blade 504 and the lower blade 501.

[0026] Referring to Figure 2 , the positioning mechanism 505 includes a connecting plate 5051 fixedly arranged on one side of the upper blade 504. Two telescopic rods 5052 are installed at the bottom of the connecting plate 5051. A pressing plate 5053 is installed at the bottom ends of the telescopic rods 5052. A return spring 5054 is sleeved on the surface of the telescopic rods 5052. When the upper blade 504 is driven by the hydraulic rod 503 to move downward, the pressing plate 5053 moves downward accordingly, and the pressing plate 5053 will contact the surface of the plate prior to the upper blade 504. Under the action of the telescopic rods 5052 and the return spring 5054, the pressing plate 5053 exerts a certain pressure on the plate, so as to limit and fix the plate in the vertical direction.

[0027] The implementation principle of a shearing mechanism for a plate shearing machine in an embodiment of this application is as follows: Place the plate on the ramp groove 2, limit the end through the second limiting plate 403, and at the same time limit both sides through the second limiting plate 403. Then, the hydraulic rod 503 drives the upper blade 504 to move downward, and the pressing plate 5053 follows to move downward. Moreover, the pressing plate 5053 will contact the surface of the plate prior to the upper blade 504, and under the action of the telescopic rod 5052 and the return spring 5054, the pressing plate 5053 exerts a certain pressure on the plate, thereby limiting and fixing the plate in the vertical direction. The plate is sheared by the shearing force of the upper blade 504 and the lower blade 501. Then, the hydraulic rod 503 retracts. After the end of the plate is sheared, it drops from the second limiting plate 403. Then, the plate whose end loses support moves downward along the ramp groove 2 under the action of gravity until it abuts against the second limiting plate 403 again, and then repeat the shearing until the plate is completely sheared.
