Electric adjusting device for pipe shaping

Abstract

The invention discloses an electric adjusting device for pipe shaping. The device comprises a machine frame plate, a pipe diameter adjusting mechanism and a wall thickness adjusting mechanism, whereinthe pipe diameter adjusting mechanism and the wall thickness adjusting mechanism are arranged on the machine frame plate; the pipe diameter adjusting mechanism comprises a first screw rod adjusting device, a shaping wheel supporting disc, a plane spiral driving device, a supporting seat positioning disc, a rack, a transmission gear set, supporting seat positioning pull rods and a supporting seat;the wall thickness adjusting mechanism comprises a second screw rod adjusting device, a material blocking block, a driven calender roll and a driving calender roll. The electric adjusting device forthe pipe shaping can be applied to a polymer melt jet piling and forming process to realize electric adjustment of a pipe diameter and a wall thickness in the pipe forming process, so that the pipe forming efficiency is improved, the production cost and the labor intensity are reduced, and the effect of flexible production of pipes is achieved.

Description

technical field [0001] The invention relates to the technical field of polymer material processing and molding, in particular to an electric adjustment device for pipe shaping. Background technique [0002] Compared with traditional pipelines such as metal pipelines, polymer pipelines have the advantages of corrosion resistance, easy installation, energy saving, small resistance to conveying fluid, environmental protection, small heat loss when conveying heat medium, long service life and low cycle cost. Therefore, polymer pipes are widely used in water supply and drainage, natural gas transmission, building heating, power communication sheathing pipes, water-saving irrigation and other fields. [0003] At present, in addition to extrusion molding and winding welding molding, there are scholars who have proposed a polymer melt injection stacking molding process that can be used to form polymer pipes. The principle of the process is as follows: firstly, under the extrusion p...
