[0047] The above is a specific embodiment of the utility model, which significantly improves the deficiencies in the prior art, has significant shearing stability and efficiency advantages, and through structural optimization, ensures the durability and adaptability of the equipment.

[0048] Working principle and use process of the utility model:

[0049] The working principle is as follows:

[0050] Hydraulic Drive and Torque Amplification: The hydraulic cylinder 410 in the shear drive assembly provides the initial power. The output end of the hydraulic cylinder is connected to the lever link 440, which rotates the lever link on the shear frame 100. One end of the lever link amplifies the torque of the hydraulic cylinder through the lever principle, pushing the moving bar seat 420 to move horizontally, so that the cutter 300 moves downward along the guide rod 110. Through this torque amplification mechanism, the shearing force of the cutter is significantly enhanced, so that it can more stably shear harder or thicker blanks.

[0051] Vibration-assisted shearing: During the downward movement of the cutter 300, the vibration motor group 230 in the pillow bar assembly 200 is started. The vibration motor group generates high-frequency vibration through the relative movement of the vibration core rod 232 and the tooth disc seat 233. This vibration is transmitted to the blank through the pillow bar 220, so that the blank can better resist deformation and fracture when subjected to shearing force, thereby achieving more precise and clean shearing effect and reducing the generation of burrs and irregular edges.

[0052] Guiding and supporting during shearing process: The cutter 300 is guided by the guide rod 110 inside the shear frame 100 to move downward in a straight line, and cooperates with the pillow bar 220 to shear the blank. The spring 240 in the pillow bar assembly acts as a buffer and absorbs impact force, ensuring smooth operation of the entire shearing process and reducing wear and tear of the equipment.

[0053] Usage process

[0054] Preparation: Place the blank to be sheared on the pillow bar 220, aligning it with the shearing position of the cutter 300. Start the equipment, ensure that the hydraulic cylinder 410 and the vibration motor group 230 are in standby state, and check the status of the guide rod 110 and the connection parts.

[0055] Start shearing: Start the hydraulic system, the hydraulic cylinder 410 starts to work, rotates the lever link 440, and then drives the moving bar seat 420 and the cutter 300 to move downward. At the same time, start the vibration motor group 230, the meshing movement between the vibration core rod 232 and the tooth disc seat 233 generates high-frequency vibration, which is transmitted to the blank.

[0056] Shearing process: During the downward movement of the cutter 300, the vibration-assisted effect improves the shearing efficiency, so that the blank can better withstand the shearing force and ensure the neatness of the sheared surface. As the cutter continues to move downward, the blank is supported by the pillow bar 220, and through the cooperation of the hydraulic cylinder and the guide rod, the blank is precisely sheared.

[0057] Shearing is completed: After the cutter 300 completes the downward movement, the hydraulic cylinder 410 drives the cutter to return to the original position, and the equipment returns to the initial state.

[0058] Take out the sheared blank and check the shearing effect to ensure that the shearing quality of the blank meets the requirements.

[0059] Device reset and maintenance: after completing a shearing operation, the device will automatically reset to the initial state. Turn off the device, check the status of each component, especially the guide rod 110, spring 240 and the working condition of the vibration motor set 230, and regularly maintain to ensure long-term stable operation of the device.

[0060] Through the above working principle and use process, the die blank shearing machine of the utility model can effectively improve the shearing precision and efficiency of the blank, adapt to the blank processing requirements of different materials and thicknesses, and meet the diversified application in industrial production.
