Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] Please refer to Figures 1-6In this embodiment of the present invention, a cold-cutting flying saw device capable of fixed-length cutting includes: a cutting mechanism 100 and a tube clamping mechanism 200. The cutting mechanism 100 is capable of cutting square tubes at a fixed distance; the tube clamping mechanism 200 is capable of clamping and limiting the square tubes. The tube clamping mechanism 200 includes two columns 201, each of which is slidably embedded with a lifting plate 204. A screw 202 is rotatably connected to each column 201 and screwed into the lifting plate 204. The top end of the screw 202 is fixedly connected to the output end of a servo motor 203. The ends of the two lifting plates 204 are fixedly connected to a U-shaped plate 205. A sliding frame 216 is slidably embedded at the center of the inner top wall of the C-shaped plate 205.

A positioning frame 211 is fixedly connected to the top of the C-shaped plate 205. A cylinder 212 is fixedly connected to the top of the positioning frame 211. A lower pressure frame 213 is fixedly connected to the bottom of the cylinder 212. The buffer pad 214 at the bottom of the lower pressure frame 213 can buffer the vibration generated during cutting, thereby improving the stability of square tube cutting. Two buffer pads 214 are symmetrically fixedly connected to the bottom of the lower pressure frame 213. A C-shaped plate 207 is fixedly connected to the bottom of each of the two columns 201. The C-shaped plate 207 is fixedly connected to the side wall of the sliding plate 103. A support roller 208 is rotatably connected to each of the two C-shaped plates 207. Cylinders 209 are fixedly connected to the opposite side walls of the square plate 205, and clamping wheels 210 are rotatably connected to the ends of the cylinders 209. The cylinders 209 on both sides drive the clamping wheels 210 to move horizontally and clamp the side walls of the square tube, thereby using the clamping mechanism 200 to conveniently limit the size of square tubes of different dimensions.

[0027] Specifically, the external material conveying structure continuously transports the square tube. The servo motor 203 in the cutting equipment drives the screw 202 to rotate, thereby driving the lifting plate 204 and the first C-shaped plate 205 to descend. The square tube is placed on the support roller 208 for transport. The first C-shaped plate 205 descends until it abuts against the top of the second C-shaped plate 207. Under the compression of the return spring 217, the top pressure roller 215 presses the top of the square tube. The cylinders 209 on both sides drive the clamping roller 210 to move horizontally and press against the side wall of the square tube for limiting. The clamping mechanism 200 can easily limit the square tubes of different sizes. When the square tube needs to be cut, the cylinder 212 drives the lower pressure frame 213 to descend and clamp the top of the square tube. The buffer pad 214 at the bottom of the lower pressure frame 213 can buffer the vibration generated during cutting, thereby improving the stability of the square tube during cutting and helping to maintain the quality of the square tube cut surface.
