Decoiler

The decoiler is made of high quality steel, match the motor from overseas with small noise and high efficiency. The feed speed could be controlled by the Panasonic frequency converter, which best speed match with the core winder, besides, it can do the positive and negative turn, and the electrical sheet could be back under the negative turn function. The decoiler with expanded function to suitable for the different size sheet coil.

Industrial Computer Control System

Equipped with industrial computer control system instead of the traditional PLC system, which is more powerful, and the arithmetic speed is more faster. The function could be added greatly because of the enormous memory, besides, the software can be updated faster and convenient. This level of industrial computer can withstand bad environment such as high/low temperature or vibration.

Open the computer, user could choose the core type or angle type according to the requirements, then input the size, the computer could calculate the size of core, the class number, sheet number and the space.

In order to make the production convenient, the computer could store 20 groups core size, and user could get it from the computer easily.

Panasonic Servo Motor

SCF-400 Wound Core Folding Machine equipped with four sets Panasonic servo motors to realize the following actions:

First servo motor: it is for the feeding roller unit, which connect to the reducer and roller, to accurately feed the materials to different position for processing.

Second servo motor: it is for folding, which supply the power for fold cutter, and could adjust the folding angle by change the mechanical travel.

Third servo motor: it is for the cutting, which connect to precision reducer, then drive the tungsten carbide cutter to cut materials.

Motion Components

Ballscrews: consist of a screw spindle and a nut integrated with rolling elements that cycle through a return mechanism. Ballscrews convert rotary motion into linear motion, and are most commonly used in industrial machinery and precision machines.

Hiwin precision ballscrews are made through a grinding process of the screw spindle. Precision ground ballscrews provide high positioning accuracy and repeatability, smooth movement and long service life.

Linear guideways: provide a type of linear motion that utilizes re-circulating rolling elements between a profiled rail and a bearing block. The coefficient of friction on a linear guideway is only 1/50 compared to a traditional slide and are able to take loads in all directions. With these features, a linear guideway can achieve high precision and greatly enhanced moving accuracy.

Tungsten Carbide Tools

The folding tools and cutter both are made of the tungsten carbide material with good abrasive resistance, besides, it has good resistance to elevated temperature which improved the cutting speed. The tungsten carbide cutter edge is more sharpper then other cutter, so the sheet is more orderly.
