Abstract
The invention relates to an air-pressure regulating automatic alarm device for a laser cutter. The air-pressure regulating automatic alarm device comprises a cutter body, wherein a laser head is arranged on the cutter body; the laser head is connected with an auxiliary gas container; the air-pressure regulating automatic alarm device is characterized in that a solenoid valve is connected between the laser head and the auxiliary gas container, wherein the solenoid valve is connected with the cutter body; an air-pressure regulating alarm display meter is connected between the solenoid valve and the laser head; the air-pressure regulating alarm display meter is connected with an alarm lamp. The air-pressure regulating automatic alarm device has the benefits that when the air pressure is higher than or lower than a set range during working, the solenoid valve controls the machine body to stop working; meanwhile, the air pressure regulating device alarms to a give warning to the operation staff, so that the working air can be checked as soon as possible, the problem that the working effect of the machine is not good due to insufficient air pressure or excessively high air pressure can be effectively solved, potential safety hazards can be effectively eliminated, the working efficiency is improved, and the potential safety hazards are lowered.
Description
(1) technical field
The present invention relates to a kind of Local Members of laser cutting machine, automatic particularly to a kind of laser cutting machine air pressure adjustment
Alarm device.
(2) background technology
With the continuous improvement of laser technology, especially cut developing rapidly of industry in sheet metal, for sheet metal
Cutting and the hybrid laser cutting machine that produced and optical-fiber laser cutting machine are required for assisting gas such as oxygen, nitrogen etc. to enter
Row cutting, oxygen, nitrogen broadly fall into hazardous gas, and either bottled gass or hydraulic pressure gas, are required in machine operation
Gas in one air pressure range is assisted, the high and low job demand that all cannot meet machine, but in the market
Hybrid laser cutting machine and optical-fiber laser cutting machine are all direct uses, have no any safeguard procedures.Air pressure is higher than normal range
When, dangerous to client and operator very big；When air pressure is less than normal range, can lead to not cut through, sheet material can be caused
Damage, or even waste monoblock sheet material.
(3) content of the invention
The present invention is in order to make up the deficiencies in the prior art, there is provided a kind of structure is simple and convenient to operate, safe and reliable, can
Improve the laser cutting machine air pressure adjustment autoalarm of work efficiency.
The present invention is achieved through the following technical solutions:
A kind of laser cutting machine air pressure adjustment autoalarm, including cutting body, cutting body is provided with laser head,
Laser head is connected with auxiliary gas box, it is characterized in that: is connected with electromagnetism between described laser head and auxiliary gas box
Valve, electromagnetic valve is connected with cutting machine body phase, is connected with air pressure adjustment alarm indicator table between electromagnetic valve and laser head, and air pressure is adjusted
Section alarm indicator table is connected with alarm lamp.
It is connected with regulating valve between described auxiliary gas box and electromagnetic valve.
Described air pressure adjustment alarm indicator table is provided with pointer.
Described air pressure adjustment alarm indicator table is provided with positive normal pressure minimum graticule, positive normal pressure peak graticule, low pressure pole
Limit value graticule and high-pressure stage limit value graticule.
The invention has the beneficial effects as follows: during work, when gas pressure is more or less than in set scope, solenoid valve control
Body quits work, and barometric control unit can be reported to the police to operator to warn simultaneously, as early as possible to work with gas look into
See, can efficiently solve because of the not enough or too high problem leading to machine operation effect bad of air pressure, can effectively exclude safety again
This pass of hidden danger；Not only improve work efficiency but also reduce the problem of potential safety hazard.
(4) brief description
The present invention is further illustrated below in conjunction with the accompanying drawings.
Accompanying drawing 1 is the structural representation of the present invention；
In figure, 1 cutting body, 2 laser heads, 3 auxiliary gas box, 4 electromagnetic valves, 5 air pressure adjustment alarm indicator tables, 6 reports
Warning lamp, 7 regulating valves, 8 pointers, 9 positive normal pressure minimum graticules, 10 positive normal pressure peak graticules, 11 lower-pressure limit value graticules, 12 is high
Pressure ultimate value graticule.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment includes cutting body 1, and cutting body 1 is provided with sharp
Shaven head 2, laser head 2 is connected with auxiliary gas box 3, is connected with electromagnetic valve 4 between laser head 2 and auxiliary gas box 3,
Electromagnetic valve 4 is connected with cutting body 1, is connected with air pressure adjustment alarm indicator table 5, air pressure between electromagnetic valve 4 and laser head 2
Adjust alarm indicator table 5 and be connected with alarm lamp 6.It is connected with regulating valve 7 between auxiliary gas box 3 and electromagnetic valve 4.Air pressure
Adjust alarm indicator table 5 and be provided with pointer 8.Air pressure adjustment alarm indicator table 5 is provided with positive normal pressure minimum graticule 9, positive normal pressure
Peak graticule 10, lower-pressure limit value graticule 11 and high-pressure stage limit value graticule 12.
Using the laser cutting machine air pressure adjustment autoalarm of the present invention, gas is assisted to go out from auxiliary gas box 3
To transmit to regulating valve 7 through trachea, after air pressure adjustment alarm indicator table 5, enter trachea, import through lathe bed tank chain
Laser head 2.Normal atmospheric pressure value scope is between positive normal pressure minimum graticule 9 and positive normal pressure peak graticule 10, when auxiliary gas
When body container 3 internal gas pressure is less than positive normal pressure minimum, when not arriving lower-pressure limit value, alarm lamp 6 will be bright, works as auxiliary gas box
When atmospheric pressure value in 3 is higher than positive normal pressure peak, alarm lamp 6 also can be bright, and when atmospheric pressure value is less than lower-pressure limit value, (i.e. pointer 8 surpasses
Cross low pressure ultimate value graticule 11) or higher than high-pressure stage limit value (i.e. pointer 8 exceedes high-pressure stage limit value graticule 12) when, electromagnetic valve 4 meeting
Control cutting body 1 starting protection system, work stoppage.
