Description
One, technical field:
The present invention relates to the prestress wire processing technique field, relate to specifically steel strand wires are applied antiseptic production technology and device.
Two, background technology:
By a central hair and many limit silks form and every central hair and Bian Si around all scribble epoxy resin anticorrosion prestress wire appear on the market already, it is varied that it applies antiseptic process, its master operation all is that steel strand wires are launched, make steel strand wires with open mode by spray equipment, each silk under the open mode is carried out behind the application synthetic resin powder tussling again through heating, cooling, with the limit silk on the central hair again." the anti-rust coating formation processing method and the device thereof that prestress steel is twisted thread " of ZL93108019.3 patent disclosure also is one of them.But in these methods, usually six limit silks after steel strand wires are opened are linearly advanced in process of production, article six, the elasticity of limit silk constantly changes in coating process, cause six limit thread tension inequalities, steel wire is collided, the twisting fault is many, and before application, the steel wire of opening is not carried out The pre-heat treatment, cause coating and steel wire basal body binding force not strong, influence product quality.
Three, technical scheme:
The technical problem to be solved in the present invention is: prestress wire each under open mode is carried out in the anticorrosion process of application synthetic resin, article six, limit thread tension inequality, steel wire is collided, the twisting fault is many, and coating and steel wire basal body binding force are not strong, influences the problem of product quality.
For this reason, solution of the present invention is: 1, by central hair length, elasticity and limit silk elasticity adjusting device steel strand wires central hair and Bian Si are adjusted, automatically adjust the pitch error of steel strand wires central hair and limit silk and adjust its tension force and error in length, the scope that increasing is adjusted center filament length degree, make that central hair is in two guiding that multiple bow tie is advanced between runners, the limit silk is the shape of falling S under the force-regulating device effect and advances, the central hair of steel strand wires and Bian Si be through after adjusting, and can avoid steel wire colliding or the phenomenon of twisting in spraying process;
2, before application, each steel wire under the steel strand wires open mode is carried out The pre-heat treatment, to improve the adhesion of coating and steel wire matrix.
Its concrete technical scheme is:
A kind of coating process of anti-corrosion layer of anti-corrosion prestressed twisted steel wire is characterized in that: except that pretreatment procedure, this method may further comprise the steps:
A, prestress wire is opened by institute's measured length successively;
B, the opened steel strand wires of cleaning; And it is air-dry under open mode;
C, adjust central hair length, elasticity and limit silk elasticity, make central hair be between two guiding runners that multiple bow tie is advanced, the limit silk is the shape of falling S and advances under the force-regulating device effect;
D, under the steel strand wires open mode, central hair and Bian Si are preheated;
E, central hair, limit silk are applied synthetic resin powder; Each silk of part of opening is carried out application synthetic resin, and heat melt and dissolved curing, cooling;
Limit filament winding central hair after f, the application forms the full coat of twisted and adorns anticorrosion prestress wire;
Full coat behind g, the twisted is adorned anticorrosion prestress wire after cooling off again, is wound into dish.
The device that a kind of coating process of anti-corrosion layer of anti-corrosion prestressed twisted steel wire is used, it comprises:
A, pretreating device: comprise derusting device, cleaning, air-dry apparatus;
B, steel strand wires device for opening: to temporarily alleviating through the central hair of institute's measured length with around many Gen Biansi of central hair;
C, central hair length, elasticity and limit silk elasticity adjusting device: be arranged between steel strand wires device for opening and the steel strand wires preheating apparatus, described central hair length adjuster is made up of two slidably lead runner and springs, realizes adjustment to center filament length degree, elasticity by the relative position between spring adjustment two guiding runners; Described limit silk elasticity adjusting device is made up of connecting rod and several force-regulating devices that are installed on the connecting rod, and two adjacent force-regulating device installation directions are relative, in each force-regulating device spring are installed, and adjust the tension force of steel wire automatically by spring;
D, preheating apparatus: constitute, be installed in two expansions by a cover high-frequency induction heating apparatus and open between the maintenance mould, be used for the central hair and the Bian Si of the steel strand wires under the open mode are preheated;
E, painting device: synthetic resin powder coated on the surface of every Gen Biansi and central hair, is heated and melt the synthetic resin that is applied on all limit silks and the central hair immediately, and cooling scribbles the limit silk and the central hair of synthetic resin then;
F, steel strand wires closure are turned round device again: be used to tighten and will scribble the limit silk of synthetic resin round the central hair twisted that scribbles synthetic resin;
G, cooling, wrap-up: after further cooling off steel strand wires, be wound into dish.
Advantage of the present invention:
The present invention by the continuous relieving apparatus of steel strand wires, carries out preheating, application to its central hair and Bian Si with the steel strand wires of cleaning surfaces under the steel strand wires open mode, then class coating material is heated melt and dissolved curing, cooling, again steel strand wires is twisted into original state again after air-dry.Through the steel strand wires after the application various corrosive environments are had good corrosion resistance, have strength characteristics identical and identical concrete binding intensity simultaneously, and its flexibility is preceding identical with application with the steel of base metal twisted wire.
Particularly because in the process of the present invention, by " central hair length; elasticity and limit silk elasticity adjusting device " to steel strand wires central hair length, elasticity and Bian Si elasticity are adjusted, can adjust the pitch error of steel strand wires central hair and limit silk automatically, its tension force and error in length, and the scope that center filament length degree is adjusted is big, making central hair be multiple bow tie between two guiding runners advances, the limit silk is the shape of falling S and advances under the force-regulating device effect, article six, the limit thread tension is even, has avoided in the central hair transmittance process breaking away from the transmission of guiding runner and has caused each bar steel wire in sleave and the spraying process to collide or the appearance of twisting fault; Secondly, before application, each steel wire under the steel strand wires open mode is carried out The pre-heat treatment, reached dry further processing, improved the adsorptivity of steel wire matrix, improved the adhesion of coating and steel wire matrix, guaranteed product quality powder.
