Technical Field

[0001] The present invention relates to a pipe processing device, in particular to an umbrella pipe processing device applied to the umbrella production field. Background Art

[0002] An umbrella is a tool for providing shade or shelter from rain or snow. It is usually made of oil paper, oilcloth or plastic cloth, and has the meaning of providing shade or shelter. The materials used to make an umbrella usually include stretchable cloth and other materials that can be used as a frame and winding threads. It is raised by hand when used. Although the main purpose of the umbrella when it was first invented was to block the sunlight, it is most often used as a tool to keep out the rain on rainy days.

[0003] The existing umbrella tubes are processed by mechanical equipment. During the processing, strong bending equipment is generally used to roll the metal strip into a round tube. After the winding is completed, the seams of the steel strip are welded, and finally the round tube is cut to a fixed length, that is, the processing of the round tube umbrella tube is completed. In order to realize the processing of hexagonal and octagonal umbrella tubes, the round tube umbrella tube needs to be shaped so that the round tube umbrella tube passes through a shaping hole and is processed into the required shape. In the process of passing through the shaping hole, the weld position of the umbrella tube is easily damaged, resulting in the umbrella tube being unqualified. In the prior art, it is necessary to manually screen whether the cut umbrella tube is damaged, which consumes a lot of time.

[0004] In order to solve the problem that the weld of the umbrella tube is easily damaged during the process of passing through the shaping hole, a metal strip rolled umbrella tube processing equipment in the market adopts a one-time processing and molding process design, which has a certain market share.

The feed hole 24 extends downward and opens downward, and the width of the feed hole 24 is greater than the diameter of the punching hole 23 .

[0031] By setting the discharge hole 24, when the punching rod 4 cooperates with the punching hole 23 of the sleeve mold 2 to punch the umbrella tube, the punching rod 4 pushes the punched umbrella tube fragments into the discharge hole 24. After the staff takes off the umbrella tube, the fragments automatically fall from the lower end opening of the discharge hole 24, so that the fragments generated by punching can fall automatically, eliminating the random cleaning steps and facilitating the subsequent grooving and punching operations.
