Description

Technical Field

[0001] The utility model relates to a pipe cutting machine, more specifically, it relates to a pipe clamping driving device. Background Art

[0002] With the development of mechanical processing technology, pipes are used in various machinery and construction projects. However, in order to make the pipes suitable for current processing needs, the pipes need to be cut to the corresponding length. After the pipes are cut, a single pipe is divided into pipes of the same length. At present, the cutting method for pipe fittings is usually to mark the surface of the pipe fittings along a fixed length and cut at the mark. The commonly used cutting tool is a grinding wheel saw, which has a fast cutting speed, but will generate a large interaction force with the pipe fittings during the cutting process, so that the pipe fittings will jump more during the cutting process, resulting in low cutting accuracy and poor flatness of the incision. The staff is required to grind the incision after cutting, which reduces the production efficiency.

[0003] When using the above-mentioned cutting method, since the cutting position is manually marked, the length of the pipe is inconsistent after cutting, and a grinding distance needs to be reserved during cutting. During the cutting process, a strong force is required to fix the pipe. If the clamping force is insufficient during the cutting process, danger may easily occur, thereby endangering the life safety of the staff. Utility Model Content
