Abstract
The utility model discloses a laser welding machine gas mixer pressure regulating device is equipped with manometer and digital display pressure relay on gas mixer. When the actual pressure is smaller than a set value, a front reversing valve is automatically opened, the gas is filled into the gas mixing cavity, and the gas supply into the laser resonant cavity is stopped; and when the actual pressure reaches a set value, closing the front reversing valve and supplying gas into the laser resonant cavity. Therefore, the fault reason can be judged quickly, the fault extension is avoided, the service life of the gas mixer is prolonged, the shutdown time and the shutdown times are reduced, and the spare part cost is saved.
Description
Technical field
The utility model belongs to the automatic control equipment field, relates in particular to a kind of device that is used for detecting and regulating automatically laser welder gas mixer internal pressure.
Background technology
The lasing light emitter of the laser welder that cold-strip steel is used mainly be by nitrogen, carbon dioxide and three kinds of sources of the gas of helium after the hybrid chamber of gas mixer mixes, filter via choke valve and filter again, enter then in the laserresonator, excited by electricity and produce.In the actual production process,,, need investigate one by one, therefore search the reason complexity, need plenty of time and energy because its warning number of entries is many in case lasing light emitter breaks down.Especially the actual pressure numerical value of gas mixer is not readable; not only increased the complexity of searching failure cause, and very easily caused the damage of lasing light emitter gas mixer, and damaged each time; the capital is caused and is shut down more than 5 hours, has directly increased spare parts consumption and causality loss.
Summary of the invention
The purpose of this utility model aims to provide a kind of simple in structure, can detect automatically and control gaseous pressure, reduces fault, improves the gas mixer pressure-regulating device in useful life.
For this reason, the solution taked of the utility model is:
A kind of laser welder gas mixer pressure-regulating device is characterized in that, pressure switch and Pressure gauge are installed on gas mixer, and pressure switch all is connected with pressure control computer with Pressure gauge.
Described pressure switch is the digital display type pressure switch.
Adjustment process of the present utility model and effect are:
After nitrogen, carbon dioxide and three kinds of sources of the gas of helium enter the hybrid chamber of gas mixer by the road, pressure switch and the Pressure gauge be located on the gas mixer feed back to pressure control computer with the actual gas pressure value that detects, and pressure control computer carries out pressure according to set point to be regulated.When actual pressure during, open anterior reversal valve automatically, to gas mixing interacvity air-filling and stop air feed in laserresonator less than 1.4bar; When actual pressure reaches 1.7bar, close anterior reversal valve automatically, and open rear portion reversal valve air feed in laserresonator.The utility model can be read the pressure switch reading rapidly; and compare with the Pressure gauge show value; judge failure cause fast; in time take measures to solve; avoid fault to extend; thereby improve the useful life of gas mixer, reduce downtime and shut down number of times, save the spare part expense.
Description of drawings
Accompanying drawing is a laser welder gas mixer pressure-regulating device installment state schematic diagram.
Among the figure: anterior reversal valve 1, gas mixer 2, Pressure gauge 3, pressure switch 4, rear portion reversal valve 5, choke valve 6, filter 7.
Embodiment
By accompanying drawing as seen, on the supply air line of gas mixer 2, be provided with an anterior reversal valve 1, and on the outlet pipe of gas mixer 2, be parallel with two rear portion reversal valves 5, choke valve 6 and filter 7.The utility model is that a digital display type pressure switch 4 and a Pressure gauge 3 have been installed respectively on gas mixer 2, simultaneously pressure switch 4 is connected with external pressure control computer respectively with Pressure gauge 3, to realize the automatic control of gas pressure.
When three kinds of sources of the gas after anterior reversal valve 1 enters the hybrid chamber of gas mixer 2, pressure switch 4 and Pressure gauge 3 feed back to pressure control computer with the actual detected value, when actual pressure during less than 1.4bar, anterior reversal valve 1 is opened, and two rear portion reversal valves 5 cut out; When actual pressure reached 1.7bar, anterior reversal valve 1 cut out, and two rear portion reversal valves 5 are opened, and mist enters in the laserresonator through choke valve 6 and filter 7, is subjected to electricity to excite generation laser.
Claims (2)
1. a laser welder gas mixer pressure-regulating device is characterized in that, pressure switch and Pressure gauge are installed on gas mixer, and pressure switch all is connected with pressure control computer with Pressure gauge.
