Description

The painting device of anti-corrosion layer of anti-corrosion prestressed twisted steel wire
One, technical field:
The present invention relates to the prestress wire processing technique field, relate to specifically steel strand wires are applied antiseptic process units.
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 applies antiseptic process and installs varied, its master operation all is that steel strand wires are launched, make steel strand wires with open mode by spray equipment, to each silk the state of scattering under carry out behind the application synthetic resin powder again through heating, cool off, on the central hair that the limit silk is tussled again.The enlarged diameter of each after the general steel strand wires spraying, the length of central hair will substantially exceed the limit silk when causing turning round again, for this reason, the applicant has invented " steel strand wires alleviation slow closing device " steel strand wires central hair length has been adjusted, because the adjustment to center filament length degree realizes by pulley, central hair is multiple bow tie and advances between two guiding runners, adjusting range is big, for steel strand wires central hair is worn smoothly around pulley, must be in advance the limit silk of 20～25 meters steel strand wires be blocked, only stays central hair, so as to wear around, this has just caused raw-material waste, secondly, the central hair repeated multiple times be passed two guiding runners, also be a quite loaded down with trivial details job; The 3rd, usually six limit silks after steel strand wires scatter 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 that scatters is not carried out The pre-heat treatment, cause coating and steel wire basal body binding force not strong, influence product quality.
Three, summary of the invention
The technical problem to be solved in the present invention is: prestress wire each under the state of scattering is carried out in the anticorrosion process of application synthetic resin, Bian Si must be blocked so that wear around reaching six limit thread tension inequalities, steel wire is collided, the twisting fault is many, coating and steel wire basal body binding force are not strong, influence the problem of product quality.
For this reason, solution of the present invention is: 1, the central hair length adjuster with the sister block formula changes the central hair length adjuster of being made up of a storage line tube and a cover tension force damping adjusting device into; 2, expand in preceding expansion die sinking and back and install additional by connecting rod between the die sinking and be installed in the limit silk elasticity adjusting device that 2～10 force-regulating devices on the connecting rod are formed; 3, 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 painting device of anti-corrosion layer of anti-corrosion prestressed twisted steel wire, 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 adjusting device: be arranged on and expand die sinking before the steel strand wires device for opening and open between the maintenance mould with expansion;
D, 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;
E, 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;
F, cooling, wrap-up: after further cooling off steel strand wires, be wound into dish.
It is characterized in that: described being arranged on expanded die sinking before the steel strand wires and opened the central hair length adjuster that keeps between the mould and overlap tension force damping adjusting device by a storage line tube and and form with expanding, and described storage line tube is the spindle thin cylinder; Described tension force damping adjusting device is by the carrying cylinder of tubular, gusset piece, bolt, guide pad, spring, briquetting, guide pipe is formed, tetragonal guide pipe is positioned at the carrying cylinder middle part, be fixed in the carrying cylinder by gusset piece, the bottom of the briquetting of band Baltimore groove respectively has semicircular groove, spring places the Baltimore groove of briquetting, guide pad is symmetrically located at the guide pipe two ends, bolt passes gusset piece respectively, guide pad holds out against spring, the end that tension force damping adjusting device can be socketed in storage line tube fuses with it by welding manner or other mechanical connection manners, also can be installed in two expansions and open between the maintenance mould.
As a kind of conversion of the present invention, to open in preceding expansion die sinking and expansion and to keep between the mould limit silk elasticity adjusting device being installed also, this device is made up of connecting rod and 2～10 force-regulating devices being installed on the connecting rod, and two adjacent force-regulating device installation directions are relative.
As another conversion of the present invention, open maintenance mould 12 in two expansions 1, 12 2Between install additional by the preheating apparatus device 14 that constitutes of cover high-frequency induction heating apparatus, under open mode, central hair 2a and Bian Si 2b are preheated.
Advantage of the present invention:
Because in the device of the present invention, " central hair length, elasticity adjustment " is to be undertaken by a storage line tube and a cover tension force damping adjusting device, limit silk elasticity adjusting device also is installed in addition, increase along with the central hair cumulative length, central hair in storage line tube is progressively that random coil is linear to advance, and the Bian Sicheng shape of falling S is advanced, 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 the work, needn't be at every turn all the limit silk of 20～25 meters steel strand wires to be blocked, avoided raw-material waste, the 3rd, simple to operate, during work, only needing that central hair is passed storage line tube once gets final product, simple, convenient, the 4th, before application, each steel wire under the steel strand wires open mode is carried out The pre-heat treatment, reached the dry further adsorptivity of steel wire matrix of handling, improved to powder, improve the adhesion of coating and steel wire matrix, guaranteed product quality.
