[0002] The development of CNC punching technology began in the 1950s. my country gradually established its own CNC industry by introducing and absorbing advanced foreign technologies. Currently, CNC punching machines are widely used in aerospace, automotive, and electronics industries, becoming an important part of modern manufacturing. A CNC punching machine is an automated machine tool equipped with a program control system, controlling the machining process through digital information. All operations are completed within this CNC unit, featuring high machining accuracy, large machining area, and high automation, effectively improving production efficiency and product quality. CNC punching machines are widely used in the processing of thin metal sheet parts, including various complex hole shapes and shallow drawing forming. Through simple mold combinations, significant mold costs can be saved, making them suitable for small-batch, diversified product production, meeting the rapidly changing market demands. During programming, attention must be paid to the accuracy and safety of the program to ensure machining quality.

[0003] With the rapid development of the manufacturing industry, CNC punching machines are being used more and more widely in metal sheet processing. However, traditional CNC punching machines suffer from significant vibration and impact during use, leading to a decrease in processing accuracy. Therefore, we propose a stable support CNC punching machine to solve this problem. Utility Model Content

The first buffer is provided by a spring three sleeved on the outside of the round rod. When the support leg moves the round rod, it compresses the large spring sleeved on the outside of the round rod. At the same time, the support leg drives two blocks and a pair of small springs to compress, providing a second buffer.
