Abstract
The utility model relates to a male die extrusion protecting mechanism used for a self-control type automatic forging press machine. The mechanism mainly aims at solving the problem that during abnormal upsetting of a male die extrusion mechanism, machine parts are damaged due to delayed shutdown caused by the absence of automatic fracture monitoring signals. The mechanism is characterized in that a through air inlet port (5) is formed on a swing rod (6) in the direction perpendicular to a safe pin (2), a cylindrical compressed air storage chamber (3) is arranged between the air inlet port (5) and the swing rod (6) in the direction parallel to the safe pin (2), a pressure switch (8) is connected at one end of the air inlet port (5), and a throttle valve (9) and a gas source (11) are connected at the other end in sequence. The protecting mechanism enhances the safety during machine operation, avoids the damage of machine parts, and realizes automatic control and safety production.
Description
Technical field:
The utility model belongs to forging press cold-forge forming field, relates in particular to a kind of autocontrol forging press formpiston and releases protection mechanism.
Background technology:
The formpiston ejecting mechanism is the important mechanism of automatic forging press cold-forging forming.Automatic forging press formpiston ejecting mechanism all is to adopt cam mechanism to drive the fork swing at present, and cold forging goods shaped portion in formpiston is released, and has an accident to prevent that product from moving with formpiston.But occur wrong or upsetting takes place when unusual in debugging, need very big power the shaped portion of goods in formpiston could be released, the as easy as rolling off a log mechanism element that causes damages.In order not damage major part in this case, adopt the version of breaking safety plug usually, what at first rupture when release power is very big is safety plug.After the safety plug fracture; because of the formpiston ejecting mechanism does not have automatic control unit; machine can't monitor break signal still in operation, only could manually shut down when parts such as smashing machine tool sends abnormal noise, and there are great potential safety hazard in people and machine.
The utility model content:
Technical problem to be solved in the utility model is at the problem that exists in the background technology; and provide a kind of autocontrol automatic forging press formpiston to release protection mechanism; this protection mechanism sends signal of telecommunication assurance machine and in time shuts down in the time of can realizing the fracture of formpiston ejecting mechanism safety plug; to avoid mechanism element to damage, automatic control and safety in production have been realized.
The invention for solving the technical problem can reach by following technical solution: this autocontrol automatic forging press formpiston is released protection mechanism and is comprised the fork that connects safety plug; on a fork, open the air admission hole of perforation with the safety plug vertical direction; be parallel to the safety plug direction between air admission hole and another fork and have cylindrical compression air apotheca; air admission hole one end connects pressure switch, and the other end is connected to choke valve, source of the gas successively.
Described compressed air apotheca connects the fork place sealing ring is housed.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: this autocontrol automatic forging press formpiston is released protection mechanism owing to use the compressed air apotheca; pressure switch; occur wrong or upsetting takes place when unusual in debugging; under safety plug crack conditions between fork; compressed air abrupt release in the air apotheca; air pressure descends near the air apotheca the pipeline; pressure switch is sent the signal of telecommunication; machine is received signal and is in time shut down; avoided machine parts impaired; improved the machine works security; improve the service behaviour of lathe, realized automatic control.This structural safety reliability height has excellent popularization and is worth.

Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is structural representations of the utility model fork 1,6;
Accompanying drawing 3 is structural representations behind fork 6 half-twists in the accompanying drawing 2;
Accompanying drawing 4 is that the A-A of fork 6 in the accompanying drawing 2 is to partial sectional view;
Accompanying drawing 5 is that the B-B of fork 6 in the accompanying drawing 2 is to cutaway view;
Accompanying drawing 6 is Automatic Control Theory figure of the present utility model.
Among the figure: 1-fork, 2-safety plug, 3-compressed air apotheca, 4-joint, 5-air admission hole, 6-fork, 7-sealing ring, 8-pressure switch, 9-choke valve, 10-safety plug connecting hole, 11-source of the gas.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
As Fig. 1 in conjunction with Fig. 2; Fig. 3; Fig. 4; shown in Figure 5; this autocontrol automatic forging press formpiston is released protection mechanism and is comprised fork 1 and the fork 6 that connects safety plug 2; the fork 1 that safety plug 2 connects by safety plug connecting hole 10; fork 6 can be swung together with the form of integral body on the bolster of forging press slide block; on fork 6, open air admission hole 5 (see figure 2)s of perforation with safety plug 2 vertical direction; it is to have cylindrical compression air apotheca 3 (see figure 4)s on safety plug connecting hole 10 directions that 1 of air admission hole 5 and fork are parallel to safety plug 2 directions; be compressed air apotheca 3 and the vertical (see figure 5) of air admission hole 5 directions; air admission hole 5 is connected pressure switch 8 by flexible pipe with joint 4 one ends; the other end is connected to choke valve 9 successively; source of the gas 11; flexible pipe is the polyurethane flexible pipe; durable, be difficult for aging.In order to reach the effect of sealing better, compressed air apotheca 3 is equipped with sealing ring 7 with fork 1 faying face place, sealing ring 7 is an O-ring seals, utilizes safety plug 2 and sealing ring 7 that fork 1, fork 6 are not leaked in conjunction with the compressed air in tight and the air apotheca.Pressure switch 8 is a kind of simple pressure control devices, and when being reached rated value by measuring pressure, pressure switch can give the alarm or control signal.When safety plug 2 fractures when unusual take place in upsetting; under the cam mechanism effect; make fork 1 and fork 6 separately; cause the compressed air abrupt release of 3 li of compressed air apothecas, air pressure descends near the pipeline the air apotheca, when air pressure drops to certain value; 8 of pressure switches are sent the signal of telecommunication; machine is in time shut down after receiving signal, and the effect of choke valve 9 is to prevent that gas replenishes to the compressed air apotheca fast in the source of the gas 11, to reduce the reaction speed of pressure switch 8.
Fig. 6 is Automatic Control Theory figure of the present utility model.Described in the figure is 4 cover formpiston ejecting mechanisms, and every cover mechanism has designed compressed air apotheca 3 respectively, and the quantity of formpiston ejecting mechanism is the forming station number of lathe.Pressure switch 8 and choke valve 9 are installed near near the fuselage static the compressed air apotheca, the air apotheca is too far away if the position tripping of installing contracts, gas pressure then can take place in this pipeline to descend slower, safety plug 2 fracture back pressure switches 8 can not be sent signal at once, have reduced security reliability.
This autocontrol automatic forging press formpiston is released the service behaviour that protection mechanism has improved lathe, and the security that has improved machine works avoids machine parts impaired, has realized automatic control and safety in production.
