Description

Technical Field

[0001] The utility model relates to the field of clamping devices, and specifically to a clamping device for a numerical control cutting machine. Background Technique

[0002] The working principle of the clamping device for a numerical control cutting machine generally involves the following steps:

[0003] Clamping preparation: Before the clamping operation, the workpiece needs to be placed in the working area of the clamping device, and it is ensured that the relative position of the workpiece and the clamping device is correct;

[0004] Clamping action: The clamping device generates a clamping force through mechanical, pneumatic, hydraulic or electric means to fix the workpiece in a specified position; Common clamping methods include chuck clamping, jaw clamping, suction cup clamping, etc.;

[0005] Positioning adjustment: During the clamping process, it may be necessary to perform positioning adjustment on the workpiece to ensure the accuracy of cutting; This may involve fine-tuning the position, angle or clamping force of the clamping device, etc.;

[0006] Cutting operation: After the clamping and positioning are completed, the numerical control cutting machine can start the cutting operation; During the cutting process, the clamping device needs to keep the workpiece stable to avoid cutting deviation;

[0007] Loosen the clamping: After the cutting is completed, the clamping device needs to loosen the workpiece so as to take out the processed workpiece or replace the next workpiece to be processed;

[0008] Different types of clamping devices for numerical control cutting machines may have different working principles and characteristics, but generally speaking, their purpose is to stably clamp the workpiece and ensure the accuracy and safety of the cutting process;

[0009] When the cutting operation of the metal plate is completed, the metal plate covers the flat cutting table surface, and the flat surface of the metal plate is in full contact with the surface of the cutting table, generating a large frictional force; The frictional force is related to the contact area and surface roughness. The flat surface increases the contact area, thereby increasing the frictional force, making it difficult to remove the metal plate from the cutting table surface, increasing the cutting time cycle, and reducing the working efficiency of the cutting device.
