D control man-machine interface and PLC application in the tile press equipment - Industrial control -

A, profile tile press equipment can also be called roll type cold bending forming, namely in a row of forming mill series, contact through the metal plate and metal plate, bending, in order to make it to turn tablet need cross section shape of the plastic processing method. Before equipment arrive through encoder position, stop feeding shaft for punching and shearing operation, efficiency is low. This scheme adopts the constant feed shaft under the situation of punching and shearing.

2, technological requirements tile press in the process of punching, cutting the main feed shaft does not stop. In the forming of sheet on the pitch and the number of holes can be set, the length of the plate can be set. The main feed shaft speed is more than 30 m/min, plate length error and pitch error is less than + / - 1 mm, feeding shaft can stop at any time, after the start stop position to continue running.

3, the control system mainly adopts LEVI - d accused of man-machine interface Host the LX3VE - 700 lk two, PLC 1412 mt4h two units. Brief plan is as follows: through two sets of PLC and touch screen independent of punching and shearing part, easy to use alone. Punching parts because of using different size aperiodic model by comparing high-speed start external start signal. Through comparison external sensors and high-speed shear part start external start signal. Four, solution 1

. Relative before stop cutting way to improve the efficiency.

2。 Choose two separate sets of equipment to facilitate use, easy to produce different devices.

3。 Through data processing, the realization of electric equipment to continue running on electricity does not need to start from scratch.

5, program are briefly introduced, HMI program: run images, data, Settings, system Settings, etc.

part of PLC program:

punching part data processing

punching parts electronic CAM running start

shear part data processing

punching parts electronic CAM running start

6, project summary 1, precision punching parts meet customer requirements, speed can meet customer requirements, the speed limit by how much the number of single plate hole and the influence of hydraulic cylinder motion time

shear part 2, the system can meet customer's request, due to the independent use in order to make the punching and shearing external sensor is affected by scan cycle by changing the fixed parameters can meet the requirements.

3, the project with the modification parameters can produce different size of the plate.
