Abstract
The invention discloses a hot-dipping-plastic steel-plastic curve composite pipe production technology which comprises the steps that a steel belt with a designed width is sent into a rolling machine to form a pipe body in a spiral-winding-connecting mode; a designed length is obtained by cutting; through a transmission conveying belt, the pipe body is sent into a heater for heating; the pipe body is placed into a dipping plastic well for high-pressure adsorbing type dipping coating; and the pipe body is hung on a conveying frame for conveying, and after the pipe body is naturally cooled to normal temperature, a product is obtained by packaging. The pipe body is formed by the steel belt in the spiral-winding-connecting mode, the steel belt with one specification can be used for producing a steel pipe body with any length and diameter so that the stored number and kinds of raw materials can be obviously reduced, production cost is effectively lowered, convenience is brought to practical production, the pipe body is provided with a spiral protrusion, high-pressure adsorbing type dipping plastic PE powder is combined, corrosion resistance is improved, and anti-pressure ability is greatly improved.
Description
Technical field
The present invention relates to a kind of production technology of engineering tubing, be specifically related to a kind of hot-dip plastic steel and mould curve technique of composite tube production.
Background technique
Existing steel-plastic composite pipe by steel plate to rolling into body, anticorrosive coating and make steel-plastic composite pipe again, the composite pipe of this structure, body is by steel plate to rolling into, and body length and diameter are limited to respectively steel plate length and width, therefore, need to prepare the steel plate of a large amount of different models, could meet the user demand of the composite pipe of producing various diameters and length, the not only corresponding cost of production that improved, and make troubles to production.The steel-plastic composite pipe of existing production technology, also has the defects such as corrosion-resistant, anti-pressure ability be low.
Summary of the invention
Object of the present invention is exactly the defect existing for prior art, provides a kind of hot-dip plastic steel to mould curve technique of composite tube production.
Its technological scheme is: provide a kind of hot-dip plastic steel to mould curve technique of composite tube production, its method step is as follows:
(1) by the steel band of design width, by steel band unwinding and winding mechanism, to send into winding machine spiral winding and engage, the both sides of joint close place steel band oppositely fasten rolling after turnover and form body closely knit connection, that form helical raised on outer wall;
(2) body spiral winding being engaged, is cut into design length, makes a call to a circular hole its two end part one side is each;
(3) through the body of step (2), by chain driving conveyor belt, send into heater and heat, make body heating-up temperature reach 160-280 DEG C;
(4) by the body after heated, the circular hole by its end also utilizes hanging to sling, and vertically puts into soak and moulds well and carry out High Pressure Absorption formula and soak and mould;
(5) by through soaking the body after moulding, hang on transmission rack by the circular hole of its end, carry and be naturally cooled to after normal temperature, be packaged into product.
Described steel band is Galvanized Steel Strip, and its width is 150-160mm.The height of described helical raised is 5-7mm, and its helix pitch is 120-130mm.Described High Pressure Absorption formula is soaked and is moulded as adopting pressurized gas to brush the PE powder of design powder size, and PE powder is adsorbed on body.Described PE powder powder size is selected 60-80 orders.It is 0.3-1mm that described High Pressure Absorption formula is soaked the thickness of moulding PE powder.The diameter of described circular hole is 10-16mm.Described heater is cylindric high-frequency electromagnetic heating device.The described body soaking after moulding, the transporting velocity on transmission rack is 1200mm/min.
The invention has the beneficial effects as follows: body is wound around to engage by ribbon spiral and forms, a kind of steel band of specification can production random lengths and the steel tube body of diameter, thereby can obviously reduce raw-material stockpile number and kind, effectively reduce production costs, also bring convenience to actual production; Body, with helical raised, soaks and moulds PE powder in conjunction with High Pressure Absorption formula, has increased its decay resistance, and anti-pressure ability is provided greatly.
