Automatic feeding structure of pipe cutting machine

Abstract

The utility model discloses a pipe processing device, which aims to provide an automatic feeding structure of a pipe cutting machine which can automatically feed and process and store pipes at the same time, and has high processing efficiency. The key points of the technical solution are that pipes are stacked inside a feeding rod, so that the pipe cutting machine can temporarily store a plurality of pipes before processing, and can feed the pipes in the feeding rod through a traction member and send them to a driving assembly for clamping. At the same time, during the feeding process, the movement of the pipes is limited by a material blocking assembly, so that a single pipe can be directly fed with the next pipe after processing, which greatly improves the processing efficiency of the pipes and has good practicality. In the process of clamping the pipes, the two ends of the pipes are fixed by claws and a clamping arm, and the processing process is stable. At the same time, the roller on the clamping arm can reduce the friction of the pipes when they move in the clamping assembly, thereby improving the use effect. The utility model is suitable for the technical field of pipe cutting machines.

Description

Technical Field

[0001] The utility model relates to a pipe processing device, more specifically, it relates to an automatic feeding structure of a pipe cutting machine. Background Art

[0002] In the process of round tube production, in order to make the round tube meet the production needs, it is usually necessary to cut the round tube into a suitable length. Therefore, the cutting of the round tube is an important process in the production of round tubes. A grinding wheel saw is usually used for cutting the round tube. Although the grinding wheel saw has a fast cutting speed, it is easy to deviate during the cutting process of the round tube, the cutting accuracy is low, and the flatness of the incision is poor. After the cutting is completed, the incision needs to be polished, which reduces the production efficiency.

[0003] The existing technology also has a laser tube cutting machine, which cuts round tubes through a high-power density laser beam. The cutting efficiency is high and the surface of the round tube is not damaged during the cutting process. It has been widely used in the field of round tube processing.

[0004] At present, before pipe processing, the cutting machine needs to be loaded with pipes. Citizens usually use manual loading and clamping, which is difficult to operate. In addition, the pipes are usually processed individually, resulting in low processing efficiency. At the same time, when the pipe mass is large or the pipe diameter is thick, manual loading is difficult and danger may easily occur during transportation. Utility Model Content

The telescopic cylinder 82 can adjust the relative height of the ejecting wheel 81, and the ejecting wheel 81 is a cam. During the rotation of the ejecting wheel 81, the pipe fittings placed on the upper end thereof can be driven to rise, so that the pipe fittings can correspond to the rotating cylinder 33, thereby facilitating the clamping of the pipe fittings by the claws 34.
