BRJ - type foil winding machine is applicable to the winding of the foil type round and rectangular coil of the transformers and electrical industries.According to the different working width, it can be divided into three types - BRJ -I / 1400 type, BRJ - II / 1100 type and BRJ - III / 800 type.Besides, it can also be manufactured according to the user requirements.
The foil winding takes the copper or aluminum foil bands of different thickness as the conductor, the broadband - like insulating material as layer insulation and the narrowband - like material as the end insulation, it can complete the winding on the foil winding machine at a time and then form the roll shape coil and realize the welding of the outside lead wire inside the coil and the wrapping of the outside surface at the same time.Each function of the equipment provides sufficient support for the production of foil coil in line with the requirement.The machine is considered as the essential equipment to produce the components of such electrical products.
Control System
Electronic Control System
The electronic control system adopts the self - developed source code and operating procedure, where all the production factors such as winding, bias adjusting, turns number control, various types of displays are given different instructions after the operation by the PLC control system.
Pneumatic system
The pneumatic system adopts the modular centralized control with an extensive use of silencers, getting the machine noise level lower than the similar imported equipment.The shunt pressure and flow can be independently adjusted.All the pneumatic actions are implemented and controlled by the PLC implementation program and the pneumatic piping arrangements are reasonable and reliable.
Structure and Function
Decoiling unit
As the decoiling unit of the foil band, it is provided with the follow - up function of bias adjustment in addition to supporting the coil stock and emptying.
Winding machine
The output torque realizes the winding of the coil through the winding shaft.
Foil band shearing mechanism
It is used to cut the foil band after the coil winding is completed.
Automatic welding equipment
The welding equipment can be used to complete two kinds of welding work, wherein one is to complete the welding of the lead and the foil band, while the other is the to complete the butt welding between the foil bands.
Layer insulation decoiling device
It is used to support the insulation material roll and make the insulation material generate tension in winding.
End insulation decoiling device
It is composed of the guide bar frame, the emptying frame and the swinging carriage on the upper side of the foil winding machine.
Main frame
Main frame is a frame structure formed by the combination of related components assembled together after finishing by the thick steel plate.
Technical characteristics
The equipment actuating mechanism adopts the pneumatic component control other than the motor, avoiding the phenomenon of hydraulic oil leakage;
The welding system adopts the imported linear guide rail and ball screw;
It adopts the photoelectric servo motor to control the planes of the coil face with fast response;
The decoiling machine is equipped with five alloy coating friction plates with the maximum tension of 20000 N;
The electrical appliances of the machine are controlled by PLC with frequency control.
Tension adjustment can be made on the control panel on demand and the operation is divided into manual mode and linkage mode.
