Internal forward spinning nested process composite machine tool with dual metal tubes

Abstract

The invention discloses an internal forward spinning nested process composite machine tool with dual metal tubes. The internal forward spinning nested process composite machine tool comprises a tank body (7) and a machine body (31), wherein a spindle motor (29), a travel motor (27), a spindle bearing block (2), a travel wheel bearing block (10), a sliding contact (3) and a travel contact (5) are arranged on the tank body (7); a spindle (28) is arranged on the spindle bearing block (2); a front travel wheel axle (9) and a rear travel wheel axle (4) are arranged on the travel wheel bearing block (10); a travel track (26), a sliding contact linear rail (1), a travel switch (6), a pivot seat (25) and an air cylinder (23) are arranged on the machine body (31); a clamp (24) is arranged on the pivot seat (25) and is connected with the air cylinder (23); the sliding contact (3) is arranged in the sliding contact linear rail (1). The composite machine tool is reasonable in structural design and is convenient to operate; particularly, the stability of feed travel can be maintained; a clamping force has no influence on elastic deformation of an outer pipe and plastic deformation of an inner pipe; the inner pipe and the outer pipe are combined, so that high quality can be obtained; the problems that a spinning shaft is unstable in feed, the clamping force influences the elastic deformation of the outer pipe and the plastic deformation of the inner pipe and the like during the processing in the prior art can be solved.

Description

technical field [0001] The invention relates to a compound machine tool, in particular to a double internal positive spinning nested process compound machine tool in the bimetal composite pipe processing technology, especially suitable for automatic production of bimetal composite pipes. Background technique [0002] In October 2004, the state issued the "People's Republic of China Urban Construction Industry Standard" code-named CJ / T192-2004, which confirmed the status of stainless steel-lined composite steel pipes in the application of water supply. At present, the composite pipes mainly include cold rolling composite, drawing The processing method of drawing composite and explosive composite. During the compounding process, the inner tube is plastically deformed, and the outer tube is elastically deformed. When unloading, because the springback of the outer tube is greater than that of the inner tube, the outer tube tightens the inner tube, and a tension force is formed ...
