Abstract

The invention discloses a spinning and clamping device of a spinning composite machine, aiming to solve the problems that feeding of a spinning shaft is instable in composite pipe processing, and elastic deformation of an outer pipe and plastic deformation of an inner pipe are directly affected by clamping force. A plurality of movable lifting sockets are adopted to reduce length of a cantilever of a spinning rod inside the spinning composite machine; when a spinning head passes a clamped position during spinning, a travel switch automatically opens a clamping device so that the inner and outer pipes can be clamped once again after being fully deformed. By the arrangement, feed travel can be kept stable during the spinning, the elastic deformation of the outer pipe and the plastic deformation of the inner pipe are unaffected by the clamping force, and composite quality of the inner and outer pipes can be guaranteed.

Description

technical field [0001] The invention relates to a spinning clamping device of a spinning composite machine in the bimetal composite pipe processing technology. Background technique [0002] At present, there are mainly processing methods for composite pipes, such as cold rolling composite and drawing 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 between the two tubes. , to achieve a tight mechanical bond. Generally, the length of the composite pipe is more than 6 meters. During the spinning process, the stroke of the spinning expansion head is long, and the slender spinning shaft needs to be supported in sections to maintain the stability of the feeding stroke; Multi-point clamping is required, because the clamping force of the f...
