First, the introduction of the tile press
Many modern factories, warehouses, high-rise building construction and large-scale gas stations use colored steel tiles, and even glazed tile-style colored steel tiles, making the appearance of these buildings vivid and beautiful. These colored steel tiles are produced by a special tile press using colored steel plates. The colored steel plate enters the tile press, is pressed into various shapes through various types of rollers, and cut into a certain length by the cutter. If you need a glazed tile-like one, you can also press it. In this way, a variety of colored steel tiles can be made.
Second, the introduction of processing technology
The tile press is divided into two parts, the roller table forming part and the cutter part. The forming part of the roller table is dragged by the motor, and the chain drives the rollers to rotate. The cutter part is driven by a hydraulic cylinder to move the cutter up and down, which can cut off the colored steel tile.
The production process is as follows: the colored steel plate enters the forming part of the roller table, the roll is driven by the conveyor motor for transmission, and the length is counted by the encoder at the same time, and when the processing length reaches the set length, it is cut by the hydraulic cutter part.
Third, the status quo of the tile press control system
At present, the control system of the tile press adopts the scheme of PLC + text + inverter, PLC is responsible for various logic control and length calculation, the text can complete the parameter setting, alarm display, help information, production data display, etc., the inverter controls the transmission of the roll motor, only to implement the start-stop control and speed control that accepts the PLC.
The problem with the current method is low efficiency and poor accuracy. Because the inverter uses two stages of speed to approximate and complete the length control, it is easy to overshoot when the set speed is high, the accuracy is difficult to control, and the processing efficiency cannot be satisfied when the set speed is low. Moreover, the start and stop of the inverter is slow, which also affects the production efficiency.
In order to solve the problem of production efficiency and accuracy of tile press, Saifude launched ASD600 series servo drive, which has been unanimously recognized by customers after a large number of successful applications on site. The new control system adopts the scheme of PLC + touch screen + servo, the servo accepts the pulse signal of the PLC to control the transmission of the roll, because the servo has the characteristics of fast start and stop, and the speed is higher than the inverter control, so the processing efficiency is high, and the servo accepts the pulse using position control, so the machining accuracy is high.
Fourth, the advantages of Saifrid servo applied to tile press
After using Saifs servo, there are 10 filament gaps in the lap gap of the construction process after the color plate is formed and pressed, while the lap gap after the ordinary tile press is pressed and formed will be 0.04mm to 0.1mm. The accuracy has been greatly improved.
The production and molding speed of ordinary tile press is 6 meters per minute, and the production and molding speed of the tile press using Safu servo can be doubled, and the application of Safu servo in the tile press is greatly improved from the processing efficiency and accuracy compared with the traditional control scheme.
