Problems solved by technology

The above improvements have improved work efficiency and reduced the labor intensity of operators. However, since the positioning frame moves horizontally, when the number of pipe expanding heads is large, the space required for the positioning frame to move is large, so each pipe expanding machine The floor area is very large; secondly, from the completion of the first expansion head to the completion of the last expansion head, since the positioning frame moves horizontally, when the last expansion head completes the operation, the first expansion head The distance from the working position is far away. Before the expansion operation of the next pipe blank, the first pipe expanding head must return to the working position empty, which takes a long time, which is a waste of time for mass-produced products. Yes, the production efficiency of the product is greatly reduced

Abstract

The invention discloses a turntable type automatic tube expander, which comprises a stander, a tube blank fixing mechanism arranged at one end of the stander, a tube expanding head driving device fixedly arranged at the other end of the stander, and a push rod connected with the tube expanding head driving device, wherein a round turntable is arranged between the tube blank fixing mechanism and the tube expanding head driving device, the center of the round turntable is fixedly connected with one end of a center shaft, and the other end of the center shaft is sleeved with a bearing fixed on the stander; and the turntable is provided with at least two tube expanding head fixing holes which are positioned on a concentric circle which intersects with the extending part of the push rod and takes the center of the round turntable as the center of a circle, a tube expanding head required by tube blank processing is movably inserted in the tube expanding head fixing holes, and the head of the push rod and the tail of the tube expanding head are provided with connecting mechanisms matched with each other. Compared with the prior art, the turntable type automatic tube expander has the advantages of simple and reasonable structure, less floor space and high working efficiency.

Description

technical field [0001] The invention relates to a pipe expanding machine, in particular to a rotary table type automatic pipe expanding machine. Background technique [0002] With the continuous development of metal pipes, the requirements for metal pipes are getting higher and higher. Many metal pipes need to enlarge the diameter of the port to meet the actual needs. In order to achieve this purpose, the following pipe expander has been developed. It usually includes a frame, a pipe blank fixing mechanism arranged at one end of the frame, a pipe expanding head drive device fixedly installed at the other end of the frame, a push rod connected to the pipe expander drive device, and a pipe expander head connected to the push rod. , Under the action of the pipe expanding head driving device, the push rod pushes the pipe expanding head to insert into the tube blank. Since the diameter of the pipe expanding head is larger than the inner diameter of the tube blank, the purpose of ...
