Patent ID: 8413874

Claim:
A synchronous ultrasonic metal welding device with double-heads which comprises two sets of corresponding ultrasonic welding mechanisms, characterized in that the two sets of corresponding ultrasonic welding mechanisms are installed side by side on a middle frame; the middle frame comprises assembling flanges and two sliding stop rods which are in parallel to each other; the ultrasonic welding mechanisms are disposed on the assembling flanges which are connected with driving devices respectively; the two sets of ultrasonic welding mechanisms are driven by the driving devices to move synchronously in opposite directions towards each other for synchronous double-sided welding of a workpiece; the driving devices are double-head cylinders, and output shafts of the double-head cylinders are coupled with the assembling flanges of the middle frame; the ultrasonic welding mechanisms comprise ultrasonic energy converters, assembling flanges and weld molds; the ultrasonic welding mechanisms are disposed on the assembling flanges; the assembling flanges are mounted on the middle frame; the ultrasonic welding mechanisms are perpendicular to the middle frame; the weld molds are roll weld molds; motors are disposed on the ultrasonic welding mechanisms; the motors are coupled to each other via synchronizing wheels for synchronized operation of the two sets of ultrasonic welding mechanisms.
