Abstract
The invention discloses a synchronous control system for press machines. Each press machine is provided with a PLC system. The PLC systems are connected through a communication bus. One PLC control system compares the angle and speed of multiple flywheels, and outputs signals to a variable frequency controller of one press machine to regulate the flywheel angle and speed of the press machine to sync with other press machines. The synchronous control system for press machines has the advantages that the problem of syncing multiple devices is effectively solved, production efficiency is significantly improved and maintenance time of clutches and brakes in the press machines is greatly decreased.
Description
Technical field
The present invention relates to the synchronous control system of many forcing presses that a kind of punching press uses.
Background technology
Current two above ordinary press need synchronous, are generally that forcing press adopts start stop mode realization synchronous, and efficiency can reduce more than 20%, and unfavorable to the brakes of forcing press.
Summary of the invention
Technical problem to be solved by this invention is the synchronous control system that the forcing press that a kind of production efficiency is high will be provided.
In order to solve above technical problem, the invention provides a kind of synchronous control system of forcing press, each forcing press carries PLC control system, between a plurality of PLC control systems, by communication bus, connect, the PLC control system of one is compared to a plurality of flywheel angles and the flywheel speed of input, the frequency-variable controller that outputs signal to this forcing press regulates flywheel angle and the flywheel speed of this forcing press, makes it to synchronize with all the other forcing presses.
Superior effect of the present invention is: efficiently solve the stationary problem between multiple devices, significantly improve production efficiency, and significantly reduce the maintenance time of press machine clutch-brake.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present invention;
Fig. 2 is the workflow diagram of the embodiment of the present invention.
The specific embodiment
Refer to shown in accompanying drawing, take two forcing press 1600T and 630T is example, and the invention will be further described.
1600T pressure owner motor is common alternating current generator, can not speed governing, and the number of strokes is 10 times.630T pressure owner motor is driven by frequency-variable controller, and the number of strokes is 8-14 time.Each forcing press is joined a set of three-dimensional servo feeding device, the multiple position press that is equivalent to a having electronic feed system for 1600T forcing press, combination for 630T forcing press except middle shuttle back and forth mechanism's external pressure machine and feed system, is also equivalent to a multiple position press.Because two forcing presses all adopt continuously-running duty, need to solve the stationary problem of two forcing presses.
As depicted in figs. 1 and 2, the invention provides a kind of synchronous control system of forcing press, 1600T stroke of a press angle is imported the PCL control system of 630T forcing press into through communication bus, PCL control system compares the angle of two forcing presses in real time, each stroke moving continuously at forcing press carries out the comparison of a speed speed, one of condition that should increase or reduce as 630T forcing press speed.According to the speed speed of two forcing presses and angular deviation value, 630T forcing press speed is applied to different speed correction values at different strokes, take multistage to control, little angular deviation is applied to little speed correction value, large angular deviation is applied to large speed correction value, dynamically control in real time two forcing press angular deviations, two forcing press operation angle deviations are kept within the specific limits, as 60 degree, when angular deviation exceeds set angle, stop whole line operation.
Adjusting example of the present invention:
As current 1600T, instantaneous angle 300 degree, the number of strokes is fixed value, and actual motion is slightly faster than theoretical value, and this data system is monitored actual value voluntarily;
1) angle 285 degree as instantaneous in 630T, the number of strokes is 10.37 beats/min, systematic comparison angle difference is that 630T is than slow 15 degree of 1600T, this difference is carried out and is calculated by PLC program, speed-raising output order is to 630T frequency converter, change input current, speed is brought up to 10.38 beats/min, and real system can angle adjustment complete in 1-5 stroke;
2) angle 310 degree as instantaneous in 630T, the number of strokes is 10.37 beats/min, systematic comparison angle difference is that 630T is than fast 10 degree of 1600T, this difference is carried out and is calculated by PLC program, deceleration output order is to 630T frequency converter, change input current, Speed Reduction to 10.36 beat/min, real system can angle adjustment complete in 1-5 stroke;
Because equipment is ordinary press, control system is a general configuration, and for preventing excessive adjustment, system, is progressively transitioned into soon, more progressively to slow circulation, finely tunes in adjusting in real time in from slowly from always.
