Working Principles

Refractory Series Electric Program-controlled screw press use the new type motor drive, the flywheel, flywheel sleeves, and the copper nut move forward and reverse frequently which drive the screw and slider down to eject.

The PLC as the hub of the press machine controlling system, designed with five work process, Ⅰ,Ⅱ,Ⅲ,Ⅳ,Ⅴ, the ejecting times and speed of the working process can be set up by PLC on Touch controlling Panel. After inputting the data, the motor begin to work from silence to start very quickly, drive the flywheel, copper nut rotate accurately, and the copper nut drive the screw and slider move up and down accurately. When the motor meets the rotate speed at the preset speed as the requested by the ejecting molding device, the press uses the stored energy by the flywheel, to make the shaped refractory bricks.The PLC controlling system can capture the state of the press work of each moment to make logical decision, complete the shaped brick and stop the motor.
After the flywheel release the stored energy, the motor drives the flywheel rotate reversely at once, and come into the stop state, the mechanical brake stop at the same time to make the slider return to the preset stroke position. The controlling system complete the brick forming process automatically based on the present preset speed and times, and then return to the preset stop position, the bricks is ejected out and wait for the next signal to start again.

Features

1.Simple structure, no friction discs, the motor drives the flywheel move forward and reverse, which drives the slider to move up and down to eject.

2.Convenient maintenance and less vulnerable consumable, low cost

3.Precises ejecting molding device which can make refractory bricks in good consistency shape and size

4.Designed with two modes: point and work .

Point mode: Using as adjusting and trial of tooling, Under this mode, the slider can go up and down very slowly.

Work mode: When inputting the start signal, the press processed the ejecting speed and times as preset on PLC, then stop and eject out the bricks. After that, waiting for the next start signal.

5.The function of adjusting slider stroke: Easily adjusting the slider stroke and the position of tooling

6.The function of setting the parameters on touch panel of PLC.

Speed parameter

Time parameter

The steps of ejecting molding device

The parameter of timing

7.Confidentiality and security: The press machine is designed with password. Only input the correct password can the press machine enter the operation system.

8.Operating safety: good brake system

Motor brake

Mechanical brake

Compressed air brake

9.Good lubrication function: designed with good lubrication to ensure the effective lubrication.

10.Expanding function: Can attach the automatic material feeding and brick ejecting system to be as automatic program-controlled screw press.

11.Designed with long-distance monitoring function: Can monitoring the operating process from afar.

advantages

1.No function discs, simple structure, low maintenance and repair cost

2.Precised ejecting molding device which can be controlled by PLC

3.High quality of refractory bricks

4.Easy PLC operation system

5.High efficient and energy saving

6.High level automation, saving labor cost, no need other operator.

7.High safety performance
