Description

Technical Field

[0001] The utility model relates to the field of pipe cutting, in particular to a pipe clamping device and cutting equipment. Background Art

[0002] The common pipe cutting process generally uses a conveying structure to transport the pipe, and then a laser cutting mechanism automatically cuts the pipe.

[0003] In order to prevent the pipe from swinging during the cutting process, in the prior art, a material protection device is usually provided to clamp the cut end of the pipe. The material protection device is usually composed of two clamping arms, and the two clamping arms are respectively provided with independent cylinders for driving. When the clamping arms clamp, the cylinders respectively drive the corresponding clamping arms to make the two clamping arms approach each other to clamp the pipe. Since the two clamping arms are driven by independent cylinders, the synchronization rate of the two cylinders is more important. When the synchronization rates are different, the clamping arms will cause the cut end of the pipe to shift. However, due to their respective friction and different air intake states, the synchronization rates between the cylinders are also different, which makes it difficult for the staff to debug and delays the subsequent pipe processing procedures.
