Description

Zinc-plated weight control system

Technical field

The utility model relates to the galvanizing field, particularly a kind of hot-dip galvanizing steel wire zinc layer weight control system.

Background technology

In the hot dip of steel wire zinc technology, when steel wire goes out the zinc pot, adopt air knife that the unnecessary zinc on the steel wire is removed, even with the zinc-plated weight that guarantees steel wire.Wire galvanization weight detects automatically by built-in unit, according to testing result air knife and tolerance is regulated during production.

In realizing process of the present utility model, the inventor finds that there is following problem at least in prior art: in the prior art, gas flow by the manual shift air knife, there is certain error in manual shift, thereby make zinc-plated weight error scope big, generation seriously influences very much to the zinc-coated wire surface quality, causes finished product zinc-coated wire rejection rate quite high.

The utility model content

The utility model is in order to solve the deficiencies in the prior art, a kind of zinc-plated weight control system is provided, this system is by detecting the steel wire diameter into and out of the zinc pot automatically, automatically control air knife tolerance size according to diameter variation, reduced the error that the manual control gas flow produces, thereby reduced zinc-plated weight error, improved the zinc-coated wire surface quality.

The technical scheme that its technical matters that solves the utility model adopts is:

A kind of zinc-plated weight control system mainly comprises with lower device:

Electromagnetic flow valve is used to change the gas flow towards air knife;

First patrols and examines mechanism, gauge of wire when being used for detection and exporting the zinc pot;

Second patrols and examines mechanism, described gauge of wire when being used for detection and exporting out the zinc pot;

Described first patrols and examines mechanism and described second patrols and examines mechanism and includes guide rail, servomotor, scrambler and caliper;

Output terminal and described second output terminal of patrolling and examining mechanism that data processing and control terminal, input end and described first are patrolled and examined mechanism are connected, and output terminal is connected with described electromagnetic flow valve and described scrambler.The beneficial effect of the technical scheme that the utility model embodiment provides is: by automatic control air knife tolerance size, reduced the error that the manual control gas flow produces, thereby reduced zinc-plated weight error, make Steel Wire Surface zinc-plated evenly, improve the zinc-coated wire surface quality, reduced rejection rate; Simultaneously, need not to rely on the manual control gas flow again, liberated the labour, saved human resources by this control system.

Specific embodiments

For making the purpose of this utility model, technical scheme and advantage clearer, the utility model embodiment is described in further detail below in conjunction with accompanying drawing.

Embodiment

With reference to Fig. 1, a kind of zinc-plated weight control system comprises that mainly electromagnetic flow valve 3, first patrols and examines mechanism 7, second and patrol and examine mechanism 6 and data processing and control terminal 9.

Electromagnetic flow valve 3 is used to change the gas flow towards air knife 5.

In hot dip galvanizing process, steel wire 8 is through being equipped with the zinc pot of zinc liquid, plate one deck zinc on steel wire 8 surfaces, referring to Fig. 1, when steel wire 8 goes out the zinc pot, in order to control the weight of steel wire 8 surperficial zinc, need to rely on air knife 5 to blow the unnecessary zinc liquid that steel wire 8 is taken out of off, air knife 5 can blowing compressed air, also can nitrogen blowing, and what present embodiment used is nitrogen.As shown in Figure 1, nitrogen is discharged from nitrogen pot 1, and the electromagnetic flow valve 3 of flowing through after 2 voltage stabilizings of voltage regulation of voltage regulation valve is regulated flow after flowmeter 4 flows to air knife 5 by electromagnetic flow valve 3, blows the unnecessary zinc liquid that steel wire 8 is taken out of off by air knife 5.

First patrols and examines mechanism 6 and second, and to patrol and examine mechanism 7 be by the displacement data of servomotor according to scrambler, drives caliper and move on precise guide rail, realizes patrolling and examining automatically.Mainly act on when many of productions or the not collinear footpath of many specifications product, regularly detect the line footpath data of every steel wire.

Data processing and control terminal 9, be PLC (Programmable Logic Controller, programmable logic controller (PLC)) Programmable Logic Controller such as, the output terminal and second output terminal of patrolling and examining mechanism 7 that its input end and first is patrolled and examined mechanism 6 are connected, and output terminal is connected with the scrambler and second scrambler of patrolling and examining mechanism 7 that electromagnetic flow valve 3, first is patrolled and examined mechanism 6.

First patrols and examines mechanism 6 detects the wire footpath that goes out the zinc pot after the wire galvanization, second patrols and examines mechanism 7 detects the wire footpath that steel wire advances the zinc pot, first patrols and examines mechanism 6 and second patrols and examines mechanism 7 line that records footpath data is sent to data processing and control terminal 9, data processing and control terminal 9 with first patrol and examine mechanism 6 and second patrol and examine online data that mechanism 7 records by analysis with calculate the gas flow of controlling electromagnetic flow valve 3, control described caliper by described scrambler and move by formulating displacement.

The control system that present embodiment provides has reduced the error that the manual control gas flow produces, thereby has reduced zinc-plated weight error by controlling air knife tolerance size automatically, makes Steel Wire Surface zinc-plated even, has improved the zinc-coated wire surface quality, has reduced rejection rate; Simultaneously, need not to rely on the manual control gas flow again, liberated the labour, saved human resources by this control system.

All or part of content in the technical scheme that above embodiment provides can realize that its software program is stored in the storage medium that can read by software programming, storage medium for example: the hard disk in the computing machine, CD or floppy disk.

The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
