Description
Technical field
The present invention relates to a kind of forcing press balance bar barometric control unit, especially a kind of not only can manual adjustments, but also the device of adjustment cylinder air pressure automatically, belong to metal forming machinery technical field.
Background technology
Many small ends of large pressing machine are hinged with eccentric shaft respectively, and many connecting rod lower ends are connected with slide block respectively, and during work, eccentric shaft rotates and drives many connecting rod translations, thereby band movable slider completes pressure processing.Because the quality of many connecting rods and slide block is larger, and the speed of slide block down, there is larger impact, must, by being arranged on the descending impact of compensating cylinder buffer sliding block of slide block both sides, just can avoid mold damage.
Modern forcing press is just produced and is developed towards automation direction, many forcing presses is formed to whole production line, thereby can complete from multiple pressure processing operation such as blanking, mold pressing or stamping-out, shaping etc.Different moulds is housed in each forcing press, and the technological parameter of each forcing press is also different, and compensating cylinder air pressure corresponding to different moulds is also different.The mode that existing compensating cylinder air pressure adjustment adopts manual adjustment, not only wastes time and energy, and because the difference of workman's technical merit causes air pressure adjustment inaccurate, thereby affect the normal use of whole production line.
Summary of the invention
The object of this invention is to provide a kind of not only can manual adjustments, but also the device of adjustment cylinder air pressure automatically, for regulating respectively the different compensating cylinder air pressure of many forcing presses of press production line, meet the Production requirement of press production line.
The present invention is achieved by the following technical programs:
A kind of press balance cylinder air pressure auto-manual adjusting device, comprise the first loop being formed by the first stop valve, pressure-reducing valve, the first check valve, safety valve, discharging valve and pressure sensor, the second servo loop being formed by the second stop valve, the second check valve and 3-position-3-way solenoid valve; Air inlet source communicates with gas storage bag input by the first stop valve, pressure-reducing valve, the first check valve successively, and described gas storage bag output communicates with a pair of compensating cylinder by pipeline, and gas storage bag also communicates with safety valve, discharging valve and pressure sensor; Described the second stop valve, the second check valve are connected successively with 3-position-3-way solenoid valve, the second stop valve input communicates with air inlet source with after the first stop valve input parallel connection, and 3-position-3-way solenoid valve first end communicates with gas storage bag with after the first check valve output parallel connection.
Object of the present invention can also further realize by following technical measures.
Aforesaid press balance cylinder air pressure auto-manual adjusting device, wherein the second end of 3-position-3-way solenoid valve communicates with silencer.
The present invention is simple in structure, easy to use, both can carry out manual adjustments compensating cylinder air pressure, also can be by PLC(Programmable Logic Controller) export different analog currents, thereby automatically control the required compensating cylinder air pressure of corresponding forcing press, also the barometric information of different moulds number required correspondence in different pressures machine can be stored in PLC, only need, by input mould number, just can, by automatically regulating corresponding compensating cylinder air pressure, there is very strong practicality and economy.
Advantage and disadvantage of the present invention, the non-limitative illustration by preferred embodiment below is for illustration and explanation, and these embodiment, only provide as an example with reference to accompanying drawing.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is structural representation of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As depicted in figs. 1 and 2, the present invention includes the first loop 10 being formed by the first stop valve 11, pressure-reducing valve 12, the first check valve 13, safety valve 15, discharging valve 16 and pressure sensor 17, the second servo loop 20 being formed by the second stop valve 21, the second check valve 22 and 3-position-3-way solenoid valve 23.Air inlet source 40 communicates with gas storage bag 14 inputs by the first stop valve 11, pressure-reducing valve 12, the first check valve 13 successively, gas storage bag 14 outputs communicate with a pair of compensating cylinder 30 by pipeline 18, and gas storage bag 14 also communicates with safety valve 15, discharging valve 16 and pressure sensor 17.Discharging valve 16 is for emitting in gas storage bag 14 from the isolated water of compressed air, and when pressure sensor 17 detects the air pressure of gas storage bag 14 when too high, the safety of gas storage bag 14 is guaranteed in safety valve 15 venting in time.
The second stop valve 21, the second check valve 22 are connected successively with 3-position-3-way solenoid valve 23, the second stop valve 21 inputs communicate with air inlet source 40 with after the first stop valve 21 input parallel connections, and the A end of 3-position-3-way solenoid valve 23 communicates with gas storage bag 14 with after the first check valve 13 output parallel connections.Second end (R) of 3-position-3-way solenoid valve 23 communicates with silencer 231, the noise in the time of can reducing 3-position-3-way solenoid valve 23 commutation exhaust.
When manual adjustments is of the present invention, turn pressure-reducing valve 12, reads the air pressure of required compensating cylinder 30 in conjunction with Pressure gauge, completed manual adjustments.
Automatically regulate when of the present invention, the PLC by forcing press exports different analog currents, passes the signal along to 3-position-3-way solenoid valve 23, controls on the relief piston of 3-position-3-way solenoid valve 23 and moves or move down.In the time need to turning down the air pressure of compensating cylinder 30, on relief piston, move, seat of honour spool is opened, and A mouth and R mouth are connected exhaust, can reduce air pressure; In the time need to heightening the air pressure of compensating cylinder 30, relief piston moves down, and lower seat valve core is opened, and A mouth and P mouth are connected from 40 air inlets of air inlet source, reaches the object that increases the air pressure in compensating cylinder 30.Also the different moulds number of different pressures machine in press production line can be stored in the PLC of forcing press, according to the air pressure of the required different compensating cylinder 30 of each forcing press, set respectively corresponding analog current, after start, directly input mould number, just can automatically regulate the air pressure of corresponding a pair of compensating cylinder 30.
In addition to the implementation, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
