D LEVI70LK man-machine interface and PLC control in the application of hot bending machine - Industrial control -

A, profile, hot bending machine is to use an oven, graphite mould hot bending equipment and fixtures, such as heating the glass to softening point, first through free joint molding mold pressure molding or fixed glass after 3 d surface curvature, cooling molding again. The machine adopts programmable controller ( PLC controller） Control, human-machine interface control. Can be set to cruise mode, simply press a switch can always uninterrupted operation, every operation needs to be from the past according to the disadvantages of a switch. Easy to maintenance, equipment failure alarm and show the failure point accurately.

second, the working principle of this system is to use a two jobs running at the same time control. Using two servo do two manipulator about location of modulus and pressure. Adopt two work complementary heating and forming, make use of the least amount of resources to achieve the highest efficiency. There are two step by step, through the force sensing regulation about abrasive. More stable when the glass molding, so as to get the best effect.

three, the control system using dimensional control LEVI70LK man-machine interface, PLC controller using LX3V - 1616吨, A LX3V - add an analog input module 4 AD and LX3V - analog output module 2DA- BD。 This system by PLC and servo to cooperate, make high precision pressure membrane forming, molding best effect. Using analog acquisition infrared sensors of temperature, temperature control requirements. Through the analog output to control the output current of high frequency machine, can be modified at any time the heating speed.

4, the introduction of interface 1, operation interface: is to show the production machine, as well as the choice of three operation modes. And the current operation state of the machine

2, set up the interface: is divided into five Settings interface, motor speed setting, on the left side of the pressure setting, the right side of the pressure material setting, comprehensive set. Motor speed setting can be set stepper or servo speed and running position. On the left side of the pressure and pressure on the right material is mainly set Y axis servo position of molding pressure and pressure feeding time and frequency. Integrated servo all other Settings are set parameter Settings and time Settings.

3, manual interface: can test each motor and cylinder operation is normal.

5, 1, program control is introduced about stepping through dynamics control to adjust the height. In press forming process, the strength of the current strength is greater than the set, stepping down, until the current strength is less than the setting. Pick them and put a piece of process, the strength of the current strength is greater than the set, stepping down, until the current strength is less than setting strength or setting upward top stop.

2, start, selective operation. Because the customer is to use a high-frequency heating machine, and give two heating station, respectively. So this runtime to switch the heating each other. If automatic running condition, the two location is in the forming operation, while running in the heat. Because the heating and forming the basic running time. So a set of operation of the heating system can achieve maximum benefit.

6, project summary

1, the machine can significantly reduce the staff fatigue strength, improve the work efficiency, and avoid employee because of improper operation and cause

a series of problems.

2, staff need to cool the glass into the grinding tool, will have after forming manipulator. Make the glass won't because

out for adsorption and cause the middle circle.

3 strength and speed regulation, the machine can be carried out, to achieve the most stable forming process.

4, the machine adopts PLC programming control, touch-screen to set parameters, the operation is simple and convenient.

5, the machine is suitable for any size of glass surface, mainly abrasive transformation. Number of adjustable pressure and reach any height surface accuracy. Seven, machine photos and video
