Description

Technical Field

[0001] The utility model relates to the technical field of bar processing, in particular to a sawing device for bar processing. Background Art

[0002] With the rapid development of aerospace, electronic communications, nuclear power generation and other industrial fields, metal bars, especially aluminum bars, are increasingly used. Depending on the actual working conditions, long bars often need to be cut into the required length.

[0003] The feeding mechanism of existing sawing machines is mostly a translation feeding mechanism. After sawing a workpiece, it needs to be disassembled and clamped for processing, which wastes manpower and time and has low work efficiency. At the same time, the workpiece will not be firmly positioned, causing the workpiece to rotate, and the saw blade to bend and deform. Some sawing machines also place the workpieces side by side in the feeding mechanism, sawing multiple workpieces at a time, and batch sawing. Although this improves work efficiency, it will cause the sawing mechanism to be subjected to greater force and higher temperature, affecting its service life. For this reason, we propose a sawing device for bar processing. Utility Model Content
