[0002] The cutting machine is used for the cutting and cutting of sheets in various industries, and for winding or unwinding coils. The air expansion shaft on the cutting machine is the key to the curling of materials. It is a device used to wind or unwind coils. It uses the principle of air pressure to provide support and fastening of the coil. The air expansion shaft usually consists of a hollow metal shaft and two closed end covers. There are multiple air holes inside the shaft. When using the air expansion shaft, insert the shaft into the inner diameter of the coil and transmit the air pressure to the inside of the shaft through the air source. When the air pressure increases, the shaft will expand, so that the coil is tightly fixed on the shaft.

[0003] The clamping range of the existing pneumatic shaft of the cutting machine is relatively fixed, and the position of the clamping head cannot be fine-tuned, and pneumatic shafts with different inner diameters cannot be clamped. Therefore, we propose a pneumatic shaft for the cutting machine. Utility Model Content
