Description

Technical Field

[0001] The invention belongs to the technical field of pipe processing, and in particular relates to a pipe conveying device used for cutting square and rectangular pipes. Background Art

[0002] Metal square tubes include metal square tubes and metal rectangular tubes. They are a type of hollow structural steel and are widely used in construction, vehicle manufacturing and other fields. However, there are currently no good methods and dedicated equipment for cutting metal square tubes in China. They can only be cut using an intersecting line cutting machine for cutting round tubes, or even by manual cutting. This results in poor quality and low efficiency in cutting metal square tubes, and cannot meet the requirements of cutting large quantities of workpieces.

[0003] A Chinese patent with publication number CN103753074B provides an efficient automatic metal square tube cutting machine, which realizes cutting of the workpiece by setting a cutting head that can move around the tube. A Chinese patent with publication number CN108465989A provides an efficient automatic metal square tube cutting machine, which provides a cutting head that can move around the tube after improving the drag chain structure. However, both solutions allow the entire cutting mechanism to move. However, the cutting mechanism involves pneumatic control and electric control pipelines, which is more troublesome than rotating the tube. Therefore, a tube conveying device that can rotate the tube is proposed. Summary of the invention

[0021] In this embodiment, a conveying channel 101 penetrating along the pipe conveying direction is formed on the conveyor body 1. Three rotating grooves 102 are formed inside the conveyor body 1. An annular frame 4 is installed in each of the three rotating grooves 102. The pipe positioning support 2 is fixedly installed on the inner side walls of the annular frames 4 on both sides. A driving motor 5 is fixedly installed on the inner side wall of the annular frame 4 at the middle position. The output end of the driving motor 5 is drivingly connected to a driving wheel 51.
