Description

Technical Field

[0001] The utility model relates to the technical field of cold-cut flying saw machines, in particular to a sawing component of a cold-cut flying saw machine. Background Art

[0002] Cold-cut flying saws use a high-speed steel saw blade to slowly rotate and cut welded pipes, resulting in burr-free, noiseless, and highly efficient cutting. Coolant is sprayed between the steel saw blade and the pipe to lubricate and protect it. Cold-cut flying saws are commonly used in the steel pipe cutting industry, performing continuous cutting of pipes, profiles, and other workpieces.

[0003] The prior art discloses a cold-cut flying saw machine with a coolant collection structure (publication number: CN218476094U), which includes a main support and a circulation component. A purification pool is provided on the upper left side of the main support, a collection trough is provided below the saw blade, and a drain outlet is provided at the bottom of the collection trough. The collection trough is connected to the purification pool through the drain outlet. When in use, the material is placed on a clamp provided inside the collection trough, and the material is clamped and fixed by the contraction of the clamp before cutting.

[0004] However, the above technical solutions and the prior art still have the following defects:

[0005] In the steel pipe cutting industry, after the steel pipe is produced, it is cut into sections of different lengths by a cooling flying saw. During the use of this utility model, since the length of the steel pipe before being cut into sections is long, the clamp is installed in the collection tank, which makes the process of cutting and segmenting the steel pipe limited by the length of the collection tank, making it inconvenient to continuously cut steel pipes of different lengths and sizes, thereby reducing the applicability and working efficiency of the device.

After moving to the designated cutting position, the clamping and conveying rollers 705 on both sides are driven by the servo motor 701 to approach each other to clamp and fix the workpiece. After the fixation is completed, the sawing mechanism 6 moves downward to cut the workpiece. During the cutting process, the spray head 809 sprays coolant to the cutting position for cooling. After the cutting is completed, the motor above the clamping and conveying roller 705 is driven to rotate the clamping and conveying roller 705, and the middle workpiece is conveyed to the next process through the guide roller 2 on the other side of the bottom box 1.
