Abstract
The utility model belongs to the field of steel material manufacture, in particular to a centering device of a laser welder of a steel strip continuous production line. A centering oil cylinder of the centering device is connected with a first rack with a first clamping plate. The first rack is connected with a second rack with a second clamping plate through a gear at an axially fixed position. The centering device of the laser welder of the steel strip continuous production line has the advantages that the centering accuracy is high, the centering speed is fast, the pressure of a centering block in contact with a steel strip is small, the edge of the steel strip is not bent and the like. The centering device can be widely used for the centering of welders of other types on the steel strip continuous production line, and can also be popularized for splicing in other fields and processes which have high requirements on accuracy.
Description
Technical field
The utility model belongs to steel and makes the field, is specially a kind of centralising device with steel tinuous production laser welder.
Background technology
During belt steel rolling is produced continuously, when taking the lead the magnetic tape trailer laser weld, if take the lead and the center line of the center line of magnetic tape trailer and unit does not overlap or error is larger, the steel band after welding is crooked with making, and may make steel belt deviation; Because stressed irregular, steel plate is torn in the commissure, cause the serious consequence of broken belt.Therefore, in continuous production welding process, need a kind of effective high-precision center support system of stablizing, further reduce broken belt rate, improve the reliability of welding.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of simple in structure, high-precision centralising device with steel tinuous production laser welder is provided.
For realizing above-mentioned technical purpose, the scheme that the utility model provides is: a kind of centralising device with steel tinuous production laser welder, wherein, the centering oil cylinder connects the first tooth bar with first clamping plate, and the gear that the first tooth bar is fixed by axial location is connected with the second tooth bar with second clamping plate.
And described centering oil cylinder connects with controller by pressure proportioning valve and reversal valve successively, and controller connects with pressure switch on described centering oil cylinder by holding wire.
And described controller is based on the PLC that PID controls.
The utlity model has accuracy of alignment high, fast to medium velocity, centering piece contact zones steel pressure is little, the advantages such as strip edge edge of can not bending, can be widely used in other types welding machine centering on band steel tinuous production, more extend to other field to spelling and the higher technical process of precision prescribed.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1.1 first clamping plate, the 1.2, second clamping plate, the 2.1, first tooth bar, the 2.2, second tooth bar, 3 gears, 4, the centering oil cylinder, 5, pressure proportioning valve, 6, reversal valve, 7, controller, 8, holding wire, 9, pressure switch, 10, steel plate.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The present embodiment provides a kind of centralising device with steel tinuous production laser welder, wherein, centering oil cylinder 4 connects the gear 3 that the first tooth bar 2.1, the first tooth bars 2.1 with first clamping plate 1.1 fix by axial location and is connected with the second tooth bar 2.2 with second clamping plate 1.2.Like this, under the push-and-pull action of centering oil cylinder 4, the first clamping plate 1.1 and the second clamping plate 1.2 can be moved or opposing separating in opposite directions.
As preferably, above-mentioned centering oil cylinder 4 connects with controller 7 by pressure proportioning valve 5 and reversal valve 6 successively, and controller 7 passes through holding wire 8 and connects with pressure switch 9 on described centering oil cylinder 4.
As preferably, above-mentioned controller 7 is based on the PLC that PID controls.PID controls, and claims again PID to regulate, and is the adjuster control law that is most widely used, for ratio, integration, differential are controlled.The PLC full name is Programmable Logic Controller, it is the FPGA controller, it adopts a class programmable memory, be used for its internally stored program, actuating logic computing, sequential control, regularly, the user oriented instructions such as counting and arithmetical operation, and by numeral or analog pattern input/output various types of machineries of control or production process.
General cylinder centering or oil cylinder centralising device use electromechanical stop to locate, and precision is not high, can not automatically control by data.Servomotor centering can be controlled automatically by data, has error between the plate of steel plate 10 width datas of still inputting and reality is wide, if carry out by steel plate 10 width datas of nominal, may press from both sides bad steel plate 10; If set certain error amount, the precision of centering can't guarantee again so.The utility model adopts hydraulic centralizing, can establish altogether 4 these centralising devices of cover, and 1# and 2# centralising device are at entrance side, and 3# and 4# centralising device are at outlet side.The speed of every cover centralising device is all used the automatically adjustment independent of steel plate 10 width datas of input of a pressure proportioning valve 5.Wherein the 3# centralising device is inner at the entrance clamp, and the 4# centralising device is inner at the outlet clamp, and they are parts of main frame.This center line (being also the unit centre line) that has guaranteed steel plate 10 center lines after the centering and welding machine is consistent, and the centering effect has reached the best.Centering oil cylinder 4 is anti-dressings, and when oil cylinder stretched out, the centering clamp separated, and when oil cylinder was retracted, the centering clamp closed up.When two clamps are all encountered steel plate 10, oil cylinder stops (because the speed of centering and pressure are all controlled automatically according to steel plate 10 data, can not crush steel plate 10), the pressure of rodless cavity is close to zero, the electron pressure switch 9 that be contained on centering oil cylinder 4 rodless cavities this moment sends signal, and centering is completed.Welding machine can carry out next step action.
