Embodiment Construction

[0022] The specific embodiments of the present invention will be further described with reference to the accompanying drawings.

[0023] Plastic double wall corrugated pipe winding equipment such as figure 2 , image 3 shown. The equipment consists of a bulge winding device, front and rear brackets, a power transmission device, a rotating mechanism, and a screw adjustment part. The specific structure is as follows:

[0024] 1) The uplift winding device includes a circular stick group, and a plurality of circular sticks 3 are formed into a circular stick group evenly arranged in a circle, and the diameter of the circumscribed circle of the circular stick group matches the inner diameter of the plastic pipe. Due to the phenomenon of cold shrinkage during the processing of the plastic tube, the design diameter of the circumscribed circle is slightly larger than the diameter of the product plastic tube, the front and rear diameters of the circle are also different, and the dia...

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...
