❈ Machine  Introduction

Custom toroid core winder sheet Supply for industry-1
Toroidal Core Winder

The automatic core winder for the manufacture of toroidal core made from grain oriented steel or non-oriented steel for small transformers, transmitters, instrument and voltage transformers, chokes and variable voltage transformers. The machine with the highest quality components and materials, and through the application of an advanced design, very significant economies are provided in low running costs, high speed operation and low maintenance.

The machine is equipped with the latest PLC system and HMI touch screen to control the decoiler, winding machine and laser welder. The decoiler feeds the materials to winding machine, the material through the leveling unit, deburring unit, pinch roller unit, then machine hand clamp the sheet and hook it on the mandrel, then the servo motor drive the mandrel to wind sheet into toroidal core, the laser system welds the end layer with perfect welding spot, at last, the mechanical arm pick up the cores automatically.

Laser Welder
The laser welding machine make use of the laser sources to heat and spot weld the electrical sheet, and the nominal power up to 200 watts at fundamental model beam quality. The Laser transferred by 5 meters or 10 meters fiber cable which expand working area of machine, and the weld penetration can be 0.1-1.5mm, more firm welding effect than traditional TIG welder, besides, the supply of energy can be well monitored, regulated and maintained or precisely controlled.

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, and the feeding speed up to 200m/min, the max load is about 100KG.

PLC system and HIM touch screen

Adopt high performance Panasonic FPΣ Series control system, which be able to generate accurate output pulse, and make the instruction cycle more faster and stable.

The program is designed to integrate sophisticated function to greatly reduce the time used by operator for data input. Besides, the self protecting program for all actions performed by the machine to avoid the damage.

HMI Touch Screen

The entire core making process is being monitored by the encoder, includes feeding, clamping, hooking, winding, winding, cutting, welding and pushing. The movement of the sheets can also be tracked. With the help of welding monitoring technology, the product quality is greatly enhanced to reduce failure and waste.

Using 10 inch Taiwan WEINVIEW HIM touch screen,equipped with the Cortex A8 600MHz CPU, and with clear and user friendly software.

Panasonic Servo Motor and Reducer

RC-Series core winder equipped with five sets Panasonic servo motors to realize the following actions:

First servo motor: it is for the move of moulds, which connect to the ball screw and drive the moulds of cutting and punching front and back on the linear guideway.

Second servo motor: it is for the cutting and hole punch, which connect to the reducer and punching unit, to cut and punch the less than 0.35mm silicon sheet under 2T pressure.

Third servo motor: it is for the winding, which connect to precision reducer, then drive the mandrel to wind the silicon sheet under powerful torque, and with the high positional accuracy.

Fourth servo motor: it is for pushing, which connect to the ball screw and drive the metal plate to close to the core and push the core out.

Fifth servo motor: it is for clamping, which connect to the ball screw and drive the machine hand to clamp the silicon sheet and feed it to the hook on the mandrel.

Equipped with SESAME special reducer from Taiwan, which has high efficiency, lower back lash, and lower noise.

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.

Cutting and Punching moulds- It is made of the tungsten alloy to greatly enhance the durability and cutting quality. In addition, the assembly and disassembly of cutting and punching mould can be done without any tools, which will easily replace the moulds.

Custom toroid core winder sheet Supply for industry-12
Mandrel moulds- It is installed on the winding spindle, and the hook pin on the mandrel moulds to hook the silicon sheet. Professional design of mandrel moulds allow the winder to produce toroidal cores efficiently and precisely.

Machine hand

Clamping machine hand: Some of sheets are not smooth or too narrow so that difficult hooking on the mould cause the feeding failure. Therefore the clamping and feeding hand is designed to increase the hooking opportunity.

Receiving machine hand: When the silicon core is completed,the machine hand will receive the core and take it on the chute or conveyor, which avoid the damage or out of shape by the impact.

Heat exchanger
In order to reduce the temperature of the control cabinet, we added the industrial heat exchanger for cooling, which could slow down the aging rate of the electrical components and makes the machine run at the best condition.
