Abstract

The utility model discloses a cubic apparatus press protection system, including protect function control system, analog input output module, switching value input output module, execution terminal and pressure sensor, analog input output module collect the pressure signal that pressure sensor sent to reach to protection among the control system, protection control system comes control execution terminal through control simulation volume input and output modules and switching value input and output modules. The utility model discloses a to the sampling of the actual operating duration between two data of every group among pressure sensor accumulative total, just, begin warning shut down processing if exceed the standard time scope of setting for, be in the occurence of failure that low super pressure -high temperature state led to the fact when having avoided equipment to break down always.

Description

A kind of cubic hinge press protection system

Technical field

The utility model belongs to field of mechanical technique, is specifically related to a kind of cubic hinge press protection system.

Background technology

At present, at home in superhard material process equipment, cubic hinge press is still occupied an leading position, and the loss of top hammer occupies larger ratio in production cost, ensures that the stability of control system of cubic hinge press is of crucial importance for this reason.Have also been made a large amount of precautionary measures, to reach comparatively perfect defencive function the engineers and technicians of the industry for this reason.Now with regard to pressure protect, this stresses; common cubic hinge press is only limitted to upper pressure limit and downscale protection in equipment running process in pressure protecting function; in real work; can run in super-pressure process; the faults such as oil circuit is obstructed are blocked in oil pump fault stall, hydraulic valve, make pressure be in stopping always and do not rise state, cause the long-time low-voltage high-temperature of system; blow out when operating personnel find not in time and split hammer accident, loss greatly.

Utility model content

Invention of the present utility model is exactly the generation in order to overcome the above problems.Be specially: control in real time because oil pump during super-pressure is not dragged by variable-frequency motor, the huge discharge shaft orientation plunger variable pump used at the beginning pump housing flow is changeless in theory after setting up, along with situations such as the vibrations wearing and tearing in running, the flow adjustment degree of pump body can change to some extent, pressure curve during super-pressure also offsets to some extent, again because different process curves arranges different pressure parameter points, so a constant slope curve strictly can not be fixed in the boost process of real work do tracking standard.

The technical scheme that the utility model adopts is: a kind of cubic hinge press protection system; comprise defencive function control system, analog input and output module, On-off signal output module, perform terminal and pressure sensor; the pressure signal that described analog input and output module collection pressure sensor sends; and send to in Protection control system, Protection control system controls to perform terminal by control simulation amount input/output module and On-off signal output module.

Further, the employing point of described pressure sensor is two.

The beneficial effect that the utility model produces is: the utility model have employed method the most economic, in each section of superpressure process when working operation, to be sampled two pressure reference point by pressure sensor, these two data are designed to automatically change with the different process change of system, can automatically adapt to different process curves, every section superpressure process sampling two points be one group, accumulative to the actual run time sampling between two data often organized at work, if exceed established standards time range just start shutdown process of reporting to the police, be in the accident generation that low-voltage high-temperature state causes when avoiding device fails always.

Accompanying drawing explanation

Fig. 1 is control principle drawing of the present utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1; in cubic hinge press synthesis running; host computer defencive function control system 1 carries out real-time sampling by analog input and output module 2 pairs of pressure sensors 4 to the pressure signal performed in terminal 5, feeds back to the defencive function control system 1 of control centre.In defencive function control system 1, crucial sampled point is run and start accumulation timing; and then and the standard time data comparison operation process that sets on picture of operating personnel; if comparative result just sends instruction to analog input and output module 2 and On-off signal output module 3 beyond setting range; drive execution terminal 5 to go to perform warning shutdown task, reach good protected effect.
