Abstract
The present invention provides a stepped compound winding support and insertion type structural wall pipe, which has a basic structure that a pipe with a large caliber is compounded, wound and formed from plastic belts and steel belts. The present invention is characterized in that the structural wall pipe is formed by the following procedures: A, the plastic belts are used as basic layers and are formed by screw heat winding and bonding on a mould core pipe; B, a layer of V-shaped steel belt is wound and bound outside the plastic belts; C, a layer of plastic belt is wound outside the steel belts through heat, online wires are wound around the mould core pipe which turns and moves in a parallel mode in an axial direction through screw heat in sequence, and the pipe with a large caliber is bound and formed. The present invention only needs to use the extrusion equipment of the existing plastic belts, and the production cost of the structural wall pipe is reduced greatly. The pipe with a large caliber is formed by adopting the three-step winding of heat, cold and heat, and both ends of the pipe are provided with a support and insertion opening. Polyethylene coats the steel belts, and the strength is increased. Product transportation and site operation are convenient, and the product specification is widened.
Description
Technical field
The present invention relates to a kind of stepped combined winding and socket fitting type structure wall tubing and processing method and mould, belong to plastic tube processing technique and equipment technical field.
Background technique
At present; large-diameter plastic pipe belongs to chemical building material; be to mould Dai Gang,, to be applied to municipal drainage to mould update product for cement; remote low-pressure water delivery; mine and chemical industry draining, the making of irrigation and water conservancy irrigation and ventilation duct and pressure vessels for the chemical industry etc. are to saving the energy; reduce and pollute, the protection environment is significant.Unit (extruder) mode of production is generally adopted in this production of moulding pipe at present, the pipe of moulding that is used to twine skeleton is to extrude the coated polypropylene plastics pipe of U type circular arc band (being called for short the pp pipe) mode with mould to produce, do on the tubing of basic unit as stiffening rib by the online polyethylene flat rubber belting that is wrapped in, the tubing of Sheng Chaning has following defective in this way: 1, in order to guarantee its quality of product, flat rubber belting twines very thick that basic unit often designs; 2, coated pp pipe diameter is unsuitable excessive, the size-constrained system of skeleton; In order to improve the ring stiffness of product, used the technology of plastic tape and steel band co-extrusion processing heavy caliber pipe abroad, adopt the shortcoming of this processing method to be, 1, equipment and mold all needs special making, manufacturing mechanism is than higher; 2, the quantity-produced heavy caliber pipe can't be provided with joint socket, and oversize being not easy to again of tubing transported, and adopts welding manner in the site operation, and how construction cost improves the ring stiffness of product and reduce manufacture cost than higher, becomes the subject matter of puzzlement enterprise.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of stepped combined winding and socket fitting type structure wall tubing and processing method of extruding with hot Wiring apparatus that have now at China is provided, to form new product structure, under the prerequisite of the ring stiffness that increases final products, reduce production costs.
Technological scheme of the present invention is achieved in that this stepped combined winding and socket fitting type structure wall tubing, and its basic structure is the compound Wrapping formed heavy caliber pipe of plastic tape, steel band, it is characterized in that: it is by the following steps moulding:
A, plastic tape twine molding bonded as basic unit's spiral heat on the mold core pipe;
B, the outside bonding one layer of V-shaped steel of twining of plastic tape;
One deck plastic tape is twined in C, steel band outside heat again, and the online heat of spiral successively is wrapped on the mold core pipe of rotation and axial translation, the molding bonded heavy caliber pipe.
Described stepped combined winding and socket fitting type structure wall tubing, described tubing two ends are provided with bell and spigot joint.
The processing method of described stepped combined winding and socket fitting type structure wall tubing, the plastic tape of described steps A and C are the polyethylene band.
The processing method of described stepped combined winding and socket fitting type structure wall tubing, described step C plastic tape heat are twined the back and are adopted the roller pressing that it is coated on the steel band.
Adopt processing method of the present invention, only need to utilize existing plastic tape extrusion equipment, reduce production costs significantly, adopt " heat "-" cold "-" heat " to twine for three times, form the heavy caliber pipe that two ends are provided with joint socket, the polyethylene coated steel band has increased intensity, Product transport and site operation are all more convenient, make product specification obtain expanding.
Description of drawings
Fig. 1 is a stepped combined winding and socket fitting type structure wall tubing schematic representation of the present invention
Among the figure:
1, pipe outer wall coating plastic band 2, V-arrangement steel band 3, plastic tape basic unit 4, mold core pipe 5, joint socket
Embodiment
The structure of socket type structure-wall pipe material of the present invention shown in Figure 1, main innovate point of the present invention is to utilize existing plastic tape extrusion equipment and Wiring apparatus with plastic tape 3,1, steel band 2 stepped combined windings, the mode of production that first layer plastic tape heat is twined is that an extruder is given flat rubber belting extrusion die feed, extrudes flat rubber belting and twine out semi-finished product tubing on core 4; By milling train and bender steel band is processed into needed cross section, cold being wrapped on the semi-finished product tubing as skeleton; Utilize original equipment that plastic tape heat winding for the third time is coated on the steel band again, roll extrusion becomes the production tube material.
Foregoing description only proposes as a kind of enforceable technological scheme of stepped combined winding and socket fitting type structure wall tubing of the present invention and processing method, not as the single restrictive condition to its structure itself.
