Description
Technical field
The utility model relates to the hydraulic press field.
Background technology
High speed forging hydraulic press is mainly used in the cogging of black and non-ferrous metal and the pressure hot-working of open die forgings, also is applicable to the high alloy material and the Ti alloy material of narrow forging temperature.The relief arrangement of the hydraulic control system of tradition hydraulic forging press generally adopts the three grades of relief arrangements of magnetic valve, inserted valve of hydraulic control or the ratio relief arrangement of proportional valve control, following problems that these two kinds of relief arrangements exist: 1. the quality of its unloading performance depends on field adjustable personnel's ability and operator's operant level height, and is higher to people's dependence.There is misoperation just to be very easy to produce vibration and noise slightly, equipment failure rate is increased, as joint breaking, loosening, the fracture of pipe clamp; System's welding assembly cracking etc.These have all increased maintenance load, have reduced productivity ratio, and practicality is relatively poor.2. because the hammered work environmental pollution is serious, hydraulic oil is often contaminated, causes the proportioning valve cisco unity malfunction often, causes reliability, the less stable of this class device.
Summary of the invention
The utility model is the problem that the solution prior art exists, and provides a kind of stability high, and operation, Installation and Debugging are simply, quick and stable discharges the hydraulic forging press relief arrangement of the high-pressure energy of storage in the hydraulic system automatically.
For achieving the above object, the utility model is by the following technical solutions: a kind of hydraulic forging press hydraulic system relief arrangement based on PLC control, comprise Programmable Logic Controller PLC and integrated hydraulic valve, the integrated hydraulic valve comprises the valve piece, the one-level inserted valve is housed on the valve piece, the secondary inserted valve, level Four inserted valve and pressure sensor, three grades of inserted valves are contained in level Four inserted valve top, first magnetic valve links to each other with the one-level inserted valve, second magnetic valve links to each other with the secondary inserted valve, the 3rd magnetic valve links to each other with three grades of inserted valves, and Programmable Logic Controller PLC is by the open field network and first magnetic valve, second magnetic valve, the 3rd magnetic valve and pressure sensor link to each other.
One-level inserted valve, secondary inserted valve are the inserted valve that has adjusting rod.
The port of described Programmable Logic Controller PLC is the RS232C communication interface.
Compared with prior art, the utlity model has following advantage:
⒈In the storage of all logic control performing a programmes of the utility model and the PLC, avoid because field adjustable personnel's ability and operator's human factors such as operant level height impact, vibrations etc. raising machine operational reliability.
⒉But the off-load program of the different unloading times of storing multiple sets in the PLC compares by the analysis of pressure sensor being gathered signal, and output time is the shortest, and the performing a programme that the off-load effect is best has shortened forging time, has improved productivity ratio.
⒊Adopt resistant to pollution inserted valve, avoid being made hydraulic valve produce phenomenons such as stuck, that action is insensitive, reduced fault rate, improved the stability of machine owing to fluid pollutes.
The I/O port of ⒋ Programmable Logic Controller PLC by the open field network of Devicenet respectively with one, two, three inserted valve on magnetic valve be connected with pressure sensor, avoided outer signals to disturb and interference between signals, guarantee control signal and the reliability of gathering signal effectively, thereby guaranteed the reliability of system works.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Hydraulic forging press hydraulic system relief arrangement as shown in Figure 1 based on PLC control, comprise Programmable Logic Controller PLC 1 and integrated hydraulic valve, the integrated hydraulic valve comprises valve piece 3, one-level inserted valve 6 is housed on the valve piece 3, secondary inserted valve 8, level Four inserted valve 9 and pressure sensor 4, three grades of inserted valves 10 are contained in level Four inserted valve 9 tops, first magnetic valve 5 links to each other with one-level inserted valve 6, second magnetic valve 7 links to each other with secondary inserted valve 8, the 3rd magnetic valve 11 links to each other with three grades of inserted valves 10, and Programmable Logic Controller PLC 1 is by the open field network 2 and first magnetic valve 5, second magnetic valve 7, the 3rd magnetic valve 11 and pressure sensor 4 link to each other.One-level inserted valve 6, secondary inserted valve 8 are the inserted valve that has adjusting rod.
Load Relief System with Y13-2500 type 25MN hydraulic forging press is an example, Programmable Logic Controller PLC is the CJ1 of an OMRON company series, the port of Programmable Logic Controller PLC is the RS232C communication interface, can connect computer input performing a programme by this interface, open field network adopts the open field network of Devicenet.The pressure signal that pressure sensor 4 collects is transferred to PLC by the open field network of Devicenet, PLC passes through the corresponding performing a programme of output after the identification of pressure signal, be transferred to each magnetic valve by the open field network of Devicenet again, realize the quick and stable off-load.Behind PLC output off-load signal, first magnetic valve, second magnetic valve, the 3rd magnetic valve are docile and obedient preface and are got electric opening, one-level inserted valve, secondary inserted valve, three grades of inserted valves, level Four inserted valves are also opened thereupon successively, make system unloaded, the time length that every step valve is opened is by the program setting in the PLC.By regulating the height of the throttling adjusting rod on the I and II inserted valve, can realize adjusting to each off-load inserted valve open height, realize auxiliary adjustment, make the whole system off-load quicker, steady.
Embodiment described in the utility model is illustrative; rather than it is determinate; therefore the utility model is not limited to the embodiment described in the specific embodiment; every by those skilled in the art according to other embodiments that the technical solution of the utility model draws, belong to the scope of the utility model protection equally.
