Description
Technical field
This utility model relates to a kind of tonnage instrument, specifically a kind of hydraulic type tonnage instrument.
Background technology
Hydraulic press is the servo electrohydraulic composite pressure machine full-automatic, intelligentized of the first item in pressing equipment industry, and it is compared with tradition punch press and injection molding machine, either in frame for movement, or control system and functionally have greatly breakthrough.Hydraulic press have employed double endless loop servo system control mode of independent research, hommization degree height, whole-course automation, intelligent and powerful.Existing punch press utilizes strain-type pressure transmitter to carry out Presser Dashing pressure pressure measurement, and to have response fast, the advantage that real-time is good, but due to can not be real-time in actual punching course be used for detecting pressure by pressure instrumentataion, to influence whether to produce, thus can not effectively prevent the overvoltage appeared in production process, the accident such as under-voltage to occur.
Utility model content
The purpose of this utility model is to provide a kind of hydraulic type tonnage instrument, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of hydraulic type tonnage instrument, including cam controller, power distribution cabinet, master control panel, tonnage instrument, hydraulic cylinder and pressure transducer, described cam controller is arranged on press outer upper end, described cam controller lower end is provided with power distribution cabinet, described power distribution cabinet front end is provided with master control panel, described master control panel lower end is provided with tonnage instrument, described hydraulic cylinder is arranged on the inner side of press, described pressure transducer is arranged on hydraulic cylinder, and described tonnage instrument electrically connects with cam controller, power distribution cabinet, master control panel, tonnage instrument, hydraulic cylinder respectively.
As further program of the utility model: described pressure transducer uses splashing type pressure transducer.
As this utility model further scheme: described cam controller is connected with the wheel disc of press.
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, reliable hardware handles and software algorithm is taken by tonnage instrument, fully compensate for the deficiency of hydraulic measurement, good solve the problems such as overvoltage that user run in process of production, the burn failure caused such as under-voltage and product quality be defective, product quality and production efficiency will be greatly improved.
Accompanying drawing explanation
Fig. 1 is the structural representation of hydraulic type tonnage instrument.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1，In this utility model embodiment，A kind of hydraulic type tonnage instrument，Including cam controller 1、Power distribution cabinet 2、Master control panel 3、Tonnage instrument 4、Hydraulic cylinder 5 and pressure transducer 6，Described cam controller 1 is arranged on press outer upper end，Described cam controller 1 is connected with the wheel disc of press，Described cam controller 1 lower end is provided with power distribution cabinet 2，Described power distribution cabinet front end is provided with master control panel 3，Described master control panel 3 lower end is provided with tonnage instrument 4，Described hydraulic cylinder 5 is arranged on the inner side of press，Described pressure transducer 6 is arranged on hydraulic cylinder 5，The 4-20mA electric current that pressure alteration in hydraulic cylinder 5 becomes industrial standard exports，Described pressure transducer 6 uses splashing type pressure transducer，Described tonnage instrument 4 respectively with cam controller 1、Power distribution cabinet 2、Master control panel 3、Tonnage instrument 4、Hydraulic cylinder 5 electrically connects，Described tonnage instrument 4 is provided with high-performance microcontroller.
When this utility model uses, by threeway, splashing type pressure transducer 6 is arranged on the hydraulic cylinder 5 of press, pressure alteration in hydraulic cylinder 5 is become the 4-20mA electric current of industrial standard to export by pressure transducer 6, and the current signal exported by pressure transducer 6 by the output line cable of pressure transducer 6 is accessed the signal conditioning circuit of hydraulic type tonnage instrument 4 and is acquired signal by the CPU of tonnage instrument 4 after conditioning and processes；The wheel disc of press carries with cam controller 1(press) it is connected, the microswitch of cam controller 1 exports the position that will reflect that current wheel disc is forwarded to, i.e. upper-lower position corresponding to punching module, when wheel disc reaches lower limit, workpiece is carried out punching press, now the pressure in hydraulic cylinder 5 is maximum, being triggered signal by the normally opened contact output of the microswitch of cam controller 1 slightly in advance at this and be connected to tonnage instrument 4 by cable, the CPU of tonnage instrument 4 receives and after triggering signal samples the pressure in hydraulic cylinder 5 and process；Microcontroller on tonnage instrument 4 is by controlling the triggered time, the value of sampling is compared and corresponding algorithm process, select to calculate current maximum to show in real time, when startup alarm mechanism is processed accordingly by actual stamping press more than when setting pressure.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in this utility model.Should not be considered as limiting involved claim by any reference in claim.
In addition, it is to be understood that, although this specification is been described by according to embodiment, but the most each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should can also be formed, through appropriately combined, other embodiments that it will be appreciated by those skilled in the art that as an entirety, the technical scheme in each embodiment by those skilled in the art.
