Accompanying drawing explanation
Fig. 1 is the composition structural principle schematic diagram of the tonnage monitoring device of multi-link lever press of the present invention.
Fig. 2 is the schematic diagram of the front panel of tonnage controller.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
Please refer to shown in Fig. 1, the tonnage monitoring device of multi-link lever press of the present invention comprises tonnage controller 1, sensing chip 2, host computer 3 and alarm relay 4.
Described sensing chip 2 is arranged on forcing press 5, and sensing chip 2 is connected to tonnage controller 1 by cable, and tonnage controller 1 is connected to host computer 3 by Ethernet.Tonnage controller 1 is by alarm relay 4 controlled pressure machine 5.
Described sensing chip 2 is resistive foil gauge.
The type of described sensing chip 2 and installation site are selected according to the actual machine situation of forcing press, and as being arranged on the guide pillar of forcing press 5, then sensing chip 2 selects pressure sensitive sheet, and as being arranged on the column of forcing press 5, then sensing chip 2 selects pulling force sensing chip.
If tonnage controller 1 is binary channels monitor, allow 2 sensor signal inputs, be mainly used in open-type inclinable press or gap-framepress, then described sensing chip 2 is 2, is arranged on the frame both sides of forcing press 5 respectively.If tonnage controller 1 is four-way monitor, allow 4 pressure sensor inputs, be mainly used in straight side press, then described sensing chip 2 is 4, is arranged on respectively on four columns of forcing press 5.
As shown in Figure 2, for allowing the front panel of the tonnage controller 1 of 4 pressure sensor inputs, wherein digital watch shows up-to-date peak load and setting of just reporting to the police.In Fig. 2, " 500 " in centre position are the gross tonnage of forcing press 5 punching press, and four of corner correspond respectively to four stud of forcing press 5.Button on panel is used for carrying out the setting of parameter and warning.The bezel of perpendicular row shows the tonnage trend situation at each angle.
If tonnage controller 1 adopts 24VDC system, then alarm relay 4 comprises two independent relays: one is capacity alarm relay, one is trend alarm relay, and tonnage controller 1 makes lathe stop by capacity alarm relay and trend alarm relay.If tonnage controller 1 adopts 110/200VAC system, then alarm relay 4 only has one, once any one value exceedes restriction of reporting to the police (capacity or trend are reported to the police), alarm relay 4 is connected, even if stopped by alarm relay 4 lathe.
For normal forward load, adjustable high power capacity is reported to the police as all passages of press provide overload protection.Capacity is reported to the police effective all the time, if exceed capacity warning settings, reports to the police and starts immediately.Any one passage generation capacity is reported to the police, and has corresponding trend alarm relay to connect.
For normal forward load, it is that all passages provide mould protection and improve part quality that adjustable high/low trend is reported to the police.Comprise three kinds of different patterns: peak value trend is reported to the police, adaptive peak trend is reported to the police and accommodation curve Zone Alerts.All trend is reported to the police all based on the pressure curve starting the qualified parts trend sample value of storing up in memory.Later each part force value is compared with the sampled value of storage.Any one passage occurrence tendency is reported to the police, and has corresponding trend alarm relay to connect.It not is start immediately that trend is reported to the police, but starts at the end of each stroke of lathe " TimingWindow ".Selected by the switching of operator, three kinds of trend only have one to be effective in reporting to the police.Trend is reported to the police only effective when monitoring mode, invalid at bypass mode.
Described tonnage controller 1 is connected to host computer 3 by Ethernet, described ethernet module is arranged on the inside of the door of forcing press 5, the data of the tonnage controller 1 received are changed by host computer 3, and host computer 3 obtains the corresponding peak value of forcing press 5, tonnage signal, alarm threshold are arranged and alert if.Tonnage signal data is stored in host computer 3 li, and with the form of user interface close friend display current curves figure.Equally, host computer 3 also long-rangely can arrange the alarm threshold of forcing press 5, mode of operation and trend alarm mode (peak value, adaptive peak and accommodation curve region).
The tonnage monitoring device of this multi-link lever press can also comprise palm PC 6, and described palm PC 6 connects tonnage controller 1 by infrared ray, is carried out the transmitting and receiving of signal by infrared-ray communication between tonnage controller 1 and palm PC 6.Palm PC 6 obtains some data from tonnage controller 1, data comprise: peak value tonnage, capacity are reported to the police and tonnage signal, these data can show on the palm PC 6 of individual, or also download to host computer 3 li to check, tonnage signal data is stored in host computer 3 li, and with the form of user interface close friend display current curves figure.
The foregoing is only the preferred embodiment of the invention; not in order to limit the invention; the any amendment done within all spirit in the invention and principle, equivalently to replace and improvement etc., within the protection domain that all should be included in the invention.
