Description

Technical Field

[0001] The utility model relates to the technical field of pipe processing, in particular to a pipe feeding device for a pipe processing machine and a pipe processing machine using the pipe feeding device. Background Art

[0002] In the processing of pipes, semi-automatic pipe feeding devices are increasingly widely used due to their flexibility and cost-effectiveness. The current semi-automatic pipe feeding devices can usually only feed pipes into the processing area of ​​the pipe processing machine at a fixed height and a fixed conveying posture, and then lift the pipes to the height of the chuck through the pipe support that floats and rises along the arc at the pipe processing machine. However, in the process from the pipe leaving the pipe feeding device to being lifted to the chuck height by the pipe support, especially in the case of non-circular pipes, the pipe axis position and pipe posture usually change. Specifically, when the pipe support rises along the arc and lifts the pipe from the pipe feeding device, the pipe usually deflects or even rolls to a certain extent due to the change of the support point, resulting in a change in the pipe axis position; and as the pipe support continues to be lifted along the arc, the pipe as a whole will also move along the pipe axis direction. Due to this at least partially uncontrolled change in the position and posture of the pipe, it is difficult to make the axis of the pipe transported to the chuck position coincide with the center of the chuck, which brings trouble to the clamping of the pipe.

Thereafter, the driving component 21 is similarly operated to make the material placement component 23 descend and leave the pipe, and the material placement component 23 automatically restores the initial loading posture with the help of the elastic retaining member in the process of leaving the stopper, and then the driving component 21 and / or the posture adjustment component 24 are operated to make the material placement component 23 return to the original loading posture.
