SUMWIC Machinery steplap core cutting machine distribution for Distribution Transformer

SCRV-series step lap cutting line have been designed and built by SUMWIC company, we use the good quality accessories with famous brand, includes Panasonic servo system and PLC (Japan), Servo Reducer(Taiwan), ball screw and linear guideway from Germany and Taiwan, other SMC Pneumatic components and electrical components from Japan. Automatically cut side leg, York and center leg with high precision and high performance.

The decoiler is made of high quality steel, match the motor from overseas with lower noise and high efficiency. The feed speed could be controlled by the Panasonic frequency converter, which best speed match with the main unit, besides, it could forward and reverse the raw material , and the electrical sheet could be back by reverse function. The decoiler with expanded function which is suitable for the different size sheet coil, and the feeding speed up to 80m/min, the max load is about 2000KG.  

Equipped with high performance Panasonic FP 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.

Using 15 inch Taiwan WEINVIEW HIM touch screen, equipped with the ARM9 400MHz CPU, and with clear and user friendly software, which boost the data processing and image display.

SCRV Series Step-lap core cutting line equipped with 12 Pcs Panasonic servo motors to realize the corresponding action. High-speed communication of 5Mbpulse/s achieves ultra-high-precision position control. It is faster and more stable than the traditional 500Kbpulse/s. It also greatly reduces the problem of interference between axis and axis. Equipped with SESAME special reducer from Taiwan, which has high efficiency, lower back lash, and lower noise. Besides, the design structure is more compact with light weight.

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.

Using Sumitomo servo reducer with zero backlash, which ensure the swing unit to accurately rotate with high efficiency and less vibration. The cutter be made of the tungsten carbide material with good abrasive resistance, besides, it has good resistance to elevated temperature which improved the cutting speed.

The hole-punch unit add the move function，which is easier to adjust the center position of raw material. Besides, the eccentric hole punch function is added which could adjust the distance freely, and thus increased the diversity of lamination sheet and enriched the production line, furthermore, it makes the replacement of moulds more convenient and faster.

The step lap core cutting machine use the unique design of dual V- notch unit and rotary shear unit, which could greatly shorten the length of the production line, and realize the multi-functional high speed cutting, meanwhile, it can notch different shape of silicon sheet, so that meets the design requirements of different transformer.

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

The machine added the grating sensor on two side of the shear, to improve the safety of operation. Besides, we also added the anti-locking device to make the material feed smoothly, which reduce the damage of feeding roller, servo motor and reducer,
