Abstract

The invention discloses a rotating pipe shaping and pulling device and method, and relates to the field of pipe production equipment. The device comprises a pulling sleeve arranged on a rotating pipein a sleeving manner; the two ends of the pulling sleeve are sleeved with hooping devices; a key groove is formed in the outer wall of the pulling sleeve; the key groove is fixedly connected with a rotating wheel through a key; the rotating wheel meshes with a driving wheel; one end of the driving wheel is connected with a motor through a driving shaft; the rotating wheel and the driving wheel arearranged on a transmission box body through bearings; the pulling sleeve penetrates through the rotating wheel and the transmission box body; friction blocks are evenly arranged on the inner wall ofthe pulling sleeve; and the friction blocks make contact with the outer wall of the rotating pipe. With the adoption of the shaping and pulling method of the rotating pipe shaping and pulling device,spiral pulling of the pipe in the axial direction is realized, and the pulling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of pipe production equipment, in particular to a rotating pipe shaping traction device and a method thereof. Background technique [0002] Winding molding equipment can process pre-produced plastic sheets / plates, and manufacture pipes through winding, bonding, steel embedding, glue coating and other processes, and then unload the pipes from the frame, pull out the mandrel, and obtain pipe products . In addition, there is an active-driven pulsating deformation forming equipment for ultra-high molecular weight polymer pipes, which can use the main extruder to plasticize and extrude the polymer raw materials, preform them into sheets, and then send the sheets into the pipe forming auxiliary The machine is wound into a pipe, and the pipe product is produced while rotating. Winding molding can obtain composite materials with excellent properties, process high-viscosity materials, and make full use of the excell...
