Abstract

The invention relates to a rotary extrusion precision drawing machine. The rotary extrusion precision drawing machine comprises a drawing machine body, a supporting part, a drawing part, a power part and a control part, wherein the supporting part comprises a guide plate and at least two groups of guide rails; one ends of the guide rails are vertically fixed on the outer surface of the drawing machine body; the guide plate slides along the guide rails; the drawing part comprises a fixing device and a rotary extrusion head, the fixing device does a linear motion along the guide rails, and the fixing device is coaxial to the rotary extrusion head in a working state; the fixing device is connected with the guide plate of the supporting part, and is used for sleeving a round billet; the rotary extrusion head is fixed with the drawing machine body, and the rotary extrusion head does a rotary motion; the rotary extrusion head comprises a rotary extrusion body and a stress body; the pipe wall is thinned in an extrusion manner preciously by ensuring the coaxiality of the round billet and the rotary extrusion head.

Description

technical field [0001] The invention relates to a pipe stretching machine, in particular to a pipe precision stretching machine using a rotary pressing method. Background technique [0002] In the prior art, it is easy to press and extend the metal sheet to achieve the purpose of thinning the sheet, but there is no equipment for processing and thinning the metal pipe. [0003] For example, a sheet stamping and stretching machine disclosed in Chinese patent CN201220177690.4 uses a driving mechanism to drive the first movable beam to move up and down, so that the sheet can be stretched twice to improve processing efficiency. But this equipment cannot stretch the pipe. Especially for thinner pipes, stretching and thinning is more difficult. It is necessary to ensure uniform thinning of the pipes and avoid wear and tear, which requires high precision in positioning processing. [0004] In view of the above-mentioned defects, the author of the present invention has finally obta...
