Description
Technical field
It is specially spark-erosion sinking lathe automatic fire extinguishing system trigger device the invention belongs to technical field.
Background technology
Spark-erosion sinking lathe is often accompanied by strong spark discharge, while lathe uses in electric discharge machining process
Flammable working solution (kerosene), during processing when finished surface and the very close flammable working solution surface of workpiece, once electrode
Discharged with workpiece, the working solution that ignites is easy in the presence of oxygen in atmosphere because electric spark exposes, furthermore due to
Electrical process machine long processing time, one will control more lathes, if can not take measures in time will cause serious consequence, because
This sets rational spark-erosion sinking lathe automatic fire extinguisher very necessary.
Traditional spark-erosion machine tool fire extinguisher is commonly called as 1211 extinguishing chemicals using difluorochlobromo-methane more, although it has
Good extinguishing effect, left no trace after fire extinguishing and the advantages that boiling pressure is small, but its heavy damage ozone layer, then there are 1211 to go out
Firearm internal pressure 1.3MPa, triggering use magnet control Φ 4mm needle-like iron cores, directly pierce through sealing 0.5mm thickness stainless steels
Paper tinsel discharges the mode of extinguishing chemical, because electromagnet core needs the high material of magnetic conductivity, it is impossible to from stainless steel material, therefore
The phenomenon that iron core rust stubbornly refuses to trigger often occurs for the big area of coastal air humidity, reduces the reliability of system.Dioxy
Change carbon as excellent fire extinguishing material, it is very low to obtain easy cost, is widely used in manual flammable liquid fire-extinguishing apparatus and works as
In, but (general 3Kg carbon dioxide extinguishers internal pressure 20MPa is left because carbon dioxide extinguisher internal pressure is larger
It is right), triggering manually can meet triggering requirement by the way of the arm of force is increased, and for automatic electric pole core, due to
It is difficult to directly obtain sufficiently large power triggering carbon dioxide extinguisher that power, which limits,.
The content of the invention
The purpose of the present invention is：Overcome the deficiencies in the prior art, using carbon dioxide extinguisher, there is provided a kind of electric spark into
Shape lathe automatic fire extinguishing system trigger device, is realized and is reliably touched using small power electric magnet valve cooperative mechanical link gear and spring
Send out carbon dioxide extinguisher, especially with spring bearer plate structure avoid in wet condition electromagnet core rust stubbornly refuse it is active
The influence of work, improve the reliability of total system.
The present invention technical solution be：
To achieve the above object, spark-erosion sinking lathe automatic fire extinguishing system trigger device be provided with electromagnetic link mechanism,
Spring-compressed mechanism and auxiliary support mechanism three parts.Electromagnetic link mechanism is installed on the outside of auxiliary support mechanism, mainly
By being mainly made up of magnetic valve, magnetic valve installing plate, iron core, hook and two spring gim pegs, its function is to utilize outside temperature
Spend sensor signal drive magnetic valve and hook completes the trigger action of spring-compressed mechanism；Spring-compressed mechanism is installed on auxiliary
Help between the medial and lateral fixed plate of supporting mechanism, mainly by unitary spring guider, guide blot, spring, support, spring pressure
Plate, supporting roller, sliding cylinder, startup cylinder, major axis, short axle and pressing plate short axle composition, its function mainly utilize above-mentioned group
Part completes the compression of spring and keeps operation, realizes that spring produces certain precompression for spring bearer plate, is deposited for trigger device
Energy storage capacity；Auxiliary support mechanism is made up of inner side fixed plate, outside fixed plate, lower connecting plate, safety pin and upper junction plate, its
Function is mainly used to fixed and positioned spring-compressed mechanism and electromagnetic link mechanism.
The present invention compared with prior art the advantages of be：
(1) triggering mode selected by the present invention is that small power electric magnet cooperative mechanical link gear and spring trigger titanium dioxide
Carbon fire extinguisher, difluorochlobromo-methane can be substituted with carbon dioxide extinguishing agent, the destruction to environment is avoided, reduce simultaneously
The cost of equipment.
(2) magnetic valve power is reduced from spring bearer plate structure, while spring bearer plate can not consider magnetic conductivity, select
Stainless steel material avoids the phenomenon that magnetic valve iron core rust is dead in conventional trigger mode, improves the reliability of system.
