[0002] In the blade adjustment mechanism of traditional shearing machines, on the one hand, blade adjustment mostly relies on manual operation, and positioning is performed through a mechanical dial or empirical judgment. Not only is the adjustment efficiency low, but the error is also large, making it difficult to meet the shearing needs of precision plates.

The rear end of the electric telescopic bracket 813 is arranged around the top side wall of the rotating motor 3 812. The front end of the electric telescopic bracket 813 is fixedly connected to the bottom side end of the tool housing assembly 82. The transverse moving sleeve 811 of the position adjustment assembly 81 can fine-tune the transverse position along the cutting moving assembly 7.

In conjunction with the displacement sensors 822 on the rear side and bottom side of the tool housing assembly 82, the angle and position data are fed back to the display in real time. like Figure 11 As shown, the shearing assembly 83 includes an electric cylinder 1 831, a push block 832, a rotary motor 4 833 and a shearing tool 834.

The rotary motor 4 833 drives the shearing tool 834 to rotate inside the push block 832, fine-tunes the parallelism of the cutting edge with the workpiece surface, and ensures that the shearing surface is flat. like Figure 10 As shown, the measuring and adjusting assembly 84 includes an electric cylinder 841, a lifting bracket 842 and a measuring ruler 843. The top side wall of the electric cylinder 841 is fixedly connected to the front upper end of the tool housing assembly 82, the bottom end of the electric cylinder 841 is fixedly connected to the top of the lifting bracket 842, the lifting bracket 842 is slidably connected to the grooves at both ends of the front side of the tool housing assembly 82, and the measuring ruler 843 is fixedly connected to the bottom end of the lifting bracket 842. The electric cylinder 841 drives the lifting bracket 842 to slide along the groove on the front side of the tool housing assembly 82, driving the measuring ruler 843 to descend to the surface of the workpiece. During the cutting process, the shear position deviation of the workpiece can be measured in real time as the workpiece moves; like Figure 1As shown, a control panel 9 is provided on the upper outer side of the mounting assembly 5 , and a supporting slider 10 is provided on the rear side of the shearing mechanism 8 , and the rear side of the supporting slider 10 is slidably connected to the front side of the mounting assembly 5 .
[0021] Working principle: Figures 1-11 As shown, the equipment is initialized and the position is calibrated: after the equipment is started, the base 1 provides stable support for the whole, and the workbench 2 serves as the workpiece bearing reference surface; the pushing component 4 is started first: the rotating motor 41 drives the screw rod 42 to rotate on the inner side of the guide rail 3, and the mounting component 5 is driven to slide along the top side of the guide rail 3 through the screw transmission, and the support slider 10 serves as a balanced sliding support. The bottom end of the back plate frame 51 of the mounting component 5 is connected to the screw rod 42, and the scale 52 on the inner upper end thereof displays the moving distance in real time. The operator can set the initial position through the control panel 9 to ensure that the mounting component 5 is accurately docked to the position to be sheared; Workpiece clamping and positioning: After the workpiece is placed on the workbench 2, the clamping assembly 6 starts the positioning process: the electric telescopic rod 61 extends, pushing the movable plate 62 to slide along the top side of the guide rail 3, and moving the movable plate 62 forward to the edge of the workpiece. The sliding direction of the movable plate 62 is consistent with the length direction of the workpiece; The small electric cylinder 63 drives the pressing plate 64 to descend vertically. After the pressing plate 64 contacts the surface of the workpiece, the clamping pressure is preset through the control panel 9 to adapt to workpieces of different thicknesses, avoiding damage due to overpressure or slippage due to underpressure. Finally, the workpiece is firmly fixed on the workbench 2, ensuring no displacement deviation during the shearing process. Adjustment of the transverse position of the shearing mechanism: According to the shearing requirements of the workpiece, the cutting moving component 7 adjusts the transverse position of the shearing mechanism 8: The second rotary motor 71 drives the second screw rod 72 to rotate. Since the position adjustment component 81 of the shearing mechanism 8 is movably connected to the second screw rod 72, the screw transmission drives the entire shearing mechanism 8 to slide horizontally along the mounting component 5 perpendicular to the length direction of the workpiece. At this time, the support slide 10 on the rear side of the shearing mechanism 8 slides synchronously along the front side of the mounting component 5. The sliding fit reduces the shaking of the lateral movement and ensures the lateral positioning accuracy. Multi-dimensional fine adjustment of the blade: The shearing mechanism 8 achieves three-dimensional fine adjustment and angle calibration of the blade through the cooperation of the position adjustment component 81 and the shearing component 83: Lateral and height adjustment: The lateral movable sleeve 811 of the position adjustment assembly 81 can fine-tune the lateral position along the cutting movable assembly 7; the electric telescopic bracket 813 is extended and retracted, driving the tool housing assembly 82 to rise and fall vertically, adjusting the vertical distance between the shearing tool 834 and the workpiece; Angle adjustment: Rotating motor 3 812 drives the tool housing assembly 82 to rotate, achieving fine adjustment of the cutting edge angle of the shearing tool 834 to adapt to the shearing requirements of workpieces of different materials. In conjunction with the displacement sensors 822 on the rear and bottom sides of the tool housing assembly 82, real-time angle and position data are fed back to the display; Cutting edge parallelism calibration: Rotating motor 4 833 drives the shearing tool 834 to rotate inside the push block 832, fine-tuning the parallelism between the cutting edge and the workpiece surface to ensure a smooth shearing surface; Real-time measurement and cutting execution: Before cutting, the measurement and adjustment component 84 starts the pre-positioning detection: The second electric cylinder 841 drives the lifting bracket 842 to slide along the groove on the front side of the tool housing assembly 82, driving the measuring ruler 843 to descend to the surface of the workpiece. During the cutting process, the shear position deviation of the workpiece can be measured in real time as the workpiece moves; After the measurement and calibration are completed, the shearing assembly 83 is started: the electric cylinder 831 pushes the push block 832 to descend vertically, driving the shearing tool 834 to move toward the workpiece, and the rotary motor 833 drives the shearing tool 834 to rotate to complete the shearing action. During the whole process, the displacement sensor 822 and the measuring ruler 843 are continuously monitored to ensure the shearing accuracy and reduce the deviation of the blade.
