Description

Technical Field

[0001] The utility model relates to the technical field of high-speed band sawing machines, in particular to a clamping mechanism for sawing materials. Background Art

[0002] Band saws are machine tools used for sawing various metal materials. They are divided into horizontal and vertical types according to their structure. The materials are cut by saw teeth. However, before that, special devices are needed to limit the workpiece to keep it stable.

[0003] A conveniently adjustable material clamping device for plasma cutting equipment disclosed in the Chinese utility model patent application disclosure CN207155151U is used to adjust the material clamping device according to the length or width of the material by adding a long strip, a pipe fitting, a fixing rod, a second through hole, a second pin and a connecting rod, so as to facilitate the adjustment and fixing of the material; by adding a concave plate, a groove, a universal ball, a first through hole and a first pin, it is used to fix the material according to the length or width, and the universal ball can also reduce the friction of the concave plate when sliding, so as to facilitate the movement and adjustment of the concave plate. The utility model has a simple structure and is easy to use. It is not only convenient to adjust and fix according to the size of the material, but also convenient for the operation of the staff, and improves the practicality of the clamping device. However, the existing high-speed band sawing machine has a relatively single limit device for the workpiece, which can only limit the workpiece on both sides, and cannot press and clamp the periphery according to different processing positions, resulting in the workpiece being easily offset when being sawed, and the overall limit effect is poor.
