Abstract
The utility model discloses an intelligent switching device of a four-angle leveling system master cylinder, which comprises a main cylinder, four leveling cylinders, pressure sensors and a programmable logical controller (PLC) control unit, wherein the pressure sensors are arranged on the main cylinder and the four leveling cylinders and are respectively connected to the PLC control unit; and after data processing, the PLC control unit controls the strokes of the main cylinder and the four leveling cylinders. Pressure signals of the main cylinder and the leveling cylinders are input into the PLC control unit to be subjected to data processing through the pressure sensors, the datum master cylinder is intelligently selected, and the other slave cylinders are leveled and controlled in a master-slave control way, so precise pressing and position precision control are realized in a pressing process of a press.
Description
Technical field
The utility model relates to a kind of four-corner leveling system active cylinder device for intelligently switching, particularly a kind of four-corner leveling system active cylinder device for intelligently switching that is used for large-scale drop press.
Background technology
Large-scale drop press needs to realize the precision of compacted products in pressing process, existing mode roughly by the running precision of equipment own and operating personnel's experience, is difficult to obtain satisfied control effect.The four-corner leveling system of current popular can address the above problem.But existing four-corner leveling system chooses the aspect for active cylinder and has certain problem, generally all be directly with master cylinder or a certain leveling cylinder as active cylinder, in press decline process, the master cylinder cylinder diameter is big, and stressed big, if as active cylinder, can cause the shake of leveling cylinder, thereby influenced the parallel accuracy of pressing process, and four leveling cylinders may be in pressing process, and the stressed difference of each cylinder is only operated by rule of thumb for choosing active cylinder, also can have very mistake, thereby influence is produced.Also do not have at present a kind of intelligence between master cylinder and the leveling cylinder to be chosen the device of active cylinder, come all the other slave cylinders are carried out leveling control.
The utility model content
At above-mentioned the deficiencies in the prior art part, the utility model aims to provide and a kind ofly can solve the problem that above-mentioned prior art exists effectively to realizing the four-corner leveling system active cylinder device for intelligently switching of accurate pressing stroke and positional precision control in the large-scale drop press pressing process.
To achieve these goals, the technical solution adopted in the utility model is: a kind of four-corner leveling system active cylinder device for intelligently switching, comprise master cylinder, four leveling cylinders, pressure sensor and PLC control modules, on described master cylinder and four leveling cylinders, be equipped with pressure sensor, pressure sensor is connected respectively to the PLC control module, is carried out controlling respectively after data are handled the stroke of master cylinder and four leveling cylinders by the PLC control module again.
Further, also include modifier key and indicator lamp, this modifier key is connected with the PLC control module with indicator lamp.
Further, described PLC control module includes the data analysis processing module, control master cylinder lifting module, control leveling cylinder lifting module, test module, manual control module, indicator lamp control module.
More further, the external control of described test module, manual control module is controlled by modifier key.
Further, described PLC control module includes the data analysis processing module, control master cylinder lifting module, control leveling cylinder lifting module, test module, manual control module, indicator lamp control module.
Further, after described data analysis processing module is handled sensor input signal relatively, control leveling between master cylinder and four the leveling cylinders by control master cylinder lifting module and control leveling cylinder lifting module respectively.
Further, after described data analysis processing module was handled sensor input signal relatively, controlling four leveling cylinders by control leveling cylinder lifting module was that benchmark carries out leveling with the master cylinder.
Compared with prior art, the beneficial effect of this utility model: the utility model inputs to the PLC control module by pressure sensor with the pressure signal of master cylinder and leveling cylinder to carry out data and handles, intelligence is chosen a benchmark active cylinder, with principal and subordinate's control mode all the other slave cylinders are carried out leveling control, thereby make the press pressing process realize accurately compacting and positional precision control.

Referring to Fig. 1, this four-corner leveling system active cylinder device for intelligently switching, comprise master cylinder, four leveling cylinders, pressure sensor, modifier key, indicator lamp and PLC control modules, on described master cylinder and four leveling cylinders, be equipped with pressure sensor, pressure sensor, modifier key, indicator lamp are connected with the PLC control module respectively, are carried out controlling after data are handled the stroke of master cylinder and four leveling cylinders by the PLC control module again.Described PLC control module includes the data analysis processing module, control master cylinder lifting module, control leveling cylinder lifting module, test module, manual control module, indicator lamp control module.
Referring to Fig. 2, concrete operation principle of the present utility model is: when four-corner leveling begins, by pressure sensor the pressure signal of master cylinder and four leveling cylinders is transferred to the PLC control module, carry out analyzing and processing by the data analysis processing module in the PLC control module, the pressure that detects master cylinder and four leveling cylinders does not exceed standard, initially just establish an imaginary axis as the motion benchmark, in each sampling period, the position and the imaginary axis of master cylinder and four leveling cylinders are compared, see whether the move distance of master cylinder and leveling cylinder surpasses the distance of imaginary axis, if surpassed, then shorten the motion step-length of master cylinder and four leveling cylinders by control master cylinder lifting module and control leveling cylinder lifting module, if do not surpass, then increase the motion step-length of master cylinder and four leveling cylinders by control master cylinder lifting module and control leveling cylinder lifting module.
If whether detect the pressure of master cylinder and four leveling cylinders exceeds standard, if exceed standard, just with main shaft as the motion benchmark, in each sampling period, the position of four leveling cylinders is compared with it, see whether the move distance of four leveling cylinders surpasses the distance of main shaft, if surpassed, then shorten the motion step-length of leveling cylinder,, then increase the motion step-length of leveling cylinder by control leveling cylinder lifting module if do not surpass by control leveling cylinder lifting module.
In the PLC control module, also be provided with test module, be used in debugging test running of the present utility model; Set up manual control module, can manually select main shaft or imaginary axis realize press as the motion benchmark four-corner leveling by automatically; Described test module, the external control of manual control module can be controlled realization by various modifier keys, and it is main shaft or imaginary axis that the indicator lamp control module can be indicated the current motion benchmark of operating personnel, the handled easily personnel control.
