Plastic double-wall winding corrugated pipe forming device

Abstract

The invention belongs to the technical field of forming of plastic double-wall corrugated pipes, in particular to a plastic double-wall winding corrugated pipe forming device. The invention solves the problems that the existing plastic double-wall corrugated pipe die sucking type forming mode is not suitable for production of large-caliber tubular products, and the steel belt supporting and winding type forming mode leads the product quality and the service life to be unstable. The device of the invention comprises an uplifting and winding device, and the uplifting and winding device comprises a circular stick group; the circular stick group consists of a plurality of circular sticks which are uniformly distributed and arranged into a circle, have the same diameter and can independently rotate at a constant speed in the same direction; the excircle of the circular stick group is matched with the inner diameter of a plastic double-wall winding corrugated pipe; a plurality of supporting wheels forming uplifted spiral trajectories are arranged at the rear part of the circular stick group; an outer die head is arranged at the exterior of the rear part of the circular stick group; and an inner die head is arranged at the interior of the front part of the circular stick group. The invention has the beneficial effects of improving the production efficiency, shortening the processing cycle, greatly reducing the usage of equipment, and effectively reducing the manufacturing cost of the plastic double-wall corrugated pipe.

Description

technical field [0001] The invention belongs to the technical field of plastic double-wall corrugated pipe forming, in particular to a plastic double-wall winding corrugated pipe forming device. Background technique [0002] Plastic pipes are gradually replacing traditional pipes such as cast iron pipes and cement pipes due to a series of superior properties such as light weight, corrosion resistance, small flow resistance, convenient construction and long service life. [0003] The existing plastic double-wall corrugated pipe has two forming methods, one is a mold suction forming method, and the other is a steel belt supporting winding forming method. [0004] Mold suction molding is more suitable for the molding of small-diameter plastic double-wall corrugated pipes. It has many advantages. However, when producing large-diameter pipes, it is difficult to adjust the diameter, and expensive molds need to be replaced. The equipment is large and complex, and the investment cos...
