Transformer Round Core Winding Machine

 

GWS700 Computer automatic core winding machine (5 axis)

 

The transformer Round Core Winding Machine is equipped with the latest PLC system and HMI touch screen to control the decompiler, winding machine, and laser welder. The decompiler feeds the materials to the winding machine, the material through the leveling unit, tension unit, guider unit, and deburring unit, then the machine hand will clamp and feed material from cutting molds to the mandrel, then the servo motor drives the mandrel to wind materials into the toroidal core, the laser system welds the end layer with perfect welding spot, at last, the mechanical arm picks up the cores automatically.

(2)Machine introduction

Computer-automated production provides high precision and high efficiency, reducing post-processing costs and labor requirements.

Fully closed-loop monitoring of the entire feeding, clamping, buckling, lifting, winding, cutting, welding and each process, which are completed simultaneously during the rolling production process.

The human-machine interface has clear and easy-to-understand pictures, and the control system has multiple automatic calculation functions. Input basic parameters to start production.

4) The entire machine uses world-famous imported accessories, including Taiwan Delta servo system and computer, SMC pneumatic components, Taiwan servo reducer, and other European and Japanese electrical accessories, etc.

 

(3)Introduction to the machine

1) Use five-axis Delta servo motor

A) First axis: die-cutting moving servo motor, which moves backward after the sheet is cut, allowing the clamping robot to feed the material to the spindle.

B) Second axis: material-cutting servo motor, connected to imported servo reducer and punching structure, can generate pressure below 2 tons, and can cut silicon steel sheets of 0.35mm or less.

C) Third axis: spindle servo motor, connected to imported servo reducer, drives the spindle to roll the material, with strong torque and high rotation positioning accuracy.

D) Fourth axis: material-returning servo motor, responsible for flattening and pushing out the iron core during the production process.

E) Fifth axis: clamping and feeding servo motor, which clamps the sheet to the roll die hook pin and buckles it firmly.

2) This machine uses Panasonic's high-performance PLC control system, with accurate output pulses, faster and more stable operation speed, and multiple operations written into the program, which can greatly reduce the operator's debugging time. All actions of the entire machine are equipped with self-protection programs to prevent unnecessary damage. Fully closed-loop control monitors the entire production process, including clamping, buckling, lifting, winding, cutting, welding, demoulding, etc. The human-machine interface uses a 10-inch color screen from Taiwan Vinylon, and the interface is clear, simple and easy to understand.

3) Precision ball screws are all from well-known Taiwanese brands, providing excellent precision and durability.

4) Pneumatic components use SMC series, including various cylinders, solenoid valves, magnetic sensors, precision pressure regulators, filters, air pipes and all joints, etc.

5) Electric lifting platform, in order to match coiling molds of different diameters, the workbench can be adjusted at will according to the diameter of the mold, which is convenient and quick to use.

6) Heat exchanger, in order to reduce the temperature of the control cabinet, a dedicated heat exchanger is added to cool down, which helps to slow down the aging of electrical components and keep the machine in the best operating state.

7) Carbide molds, the cutting and punching mold blades are made of carbide, and the effective shearing times can reach 300W times.

8)The machine is equipped with an automatic unloading device to facilitate operators to control and install materials.
