I Description of automatic copper tube end forming machine
This machine is designed in horizontal auto-changing forming station, capable for various copper tubing works, such as expanding, reducing, ribbing, beading, flaring, skirting, mouth ordering, etc.
There are six stations, five are of direct-pushing type, one stations is of spindle-rotating type which is used for chamfering. Exchanging among 6 stations is achieved by servo motor and program preset on HMI.
This machine is equipped with hopper for blank tubes, auto feeding.
This machine is PLC control, HMI operation, simple and convenient.
