An ultrasonic copper tube cutting and sealing machine

Abstract

The invention discloses an ultrasonic copper pipe cutting and sealing machine, which comprises a main body base and an ultrasonic transducer. The top of the main body base is provided with a detachable upper cover plate, and There is a horizontal U-shaped through-slot, the U-shaped through-slot on the upper cover and the U-shaped through-slot on the main body base cooperate to form a circular cavity, the circular cavity is provided with an annular step horizontal to the axis, and the ultrasonic transducer One end is matched with one side of the annular step and the end facing the annular step is connected with an amplitude modulator, one end of the amplitude modulator is connected with an upper welding head, one end of the upper welding head is matched with the side of the annular step away from the ultrasonic transducer, and the other end is connected There is a contact welding head, a swingable lower bracket swing arm is provided below the corresponding upper welding head on the base of the main body, and a lower welding bottom mold matched with the contact welding head is provided on the lower support swing arm. The invention provides an improved Ultrasonic copper tube cutting and sealing machine that improves the energy conversion rate while welding quality.

Description

technical field [0001] The invention relates to the field of pipe material sealing and cutting equipment, and more specifically relates to an ultrasonic copper pipe cutting and sealing machine. Background technique [0002] The ultrasonic copper tube cutting and sealing machine can be used in the cutting and sealing process of copper tubes and aluminum tubes, and the cutting and sealing can be completed at one time. The incision is neat and the sealing performance is good, and it has been applied in mobile air conditioners, refrigerators, and high-tech measuring instruments. The working principle of the ultrasonic copper tube cutting and sealing machine: the high-frequency vibration (tens of thousands of times per second) is transmitted to the metal surface to be welded, and under pressure, the two metal surfaces collide with each other to form a molecular layer The entire welding process is completed within 1 second, but the installation position of the ultrasonic transduc...

AI Technical Summary

Problems solved by technology

The working principle of the ultrasonic copper tube cutting and sealing machine: high-frequency vibration (tens of thousands of times per second) is transmitted to the metal surface to be welded, and under pressure, the two metal surfaces collide with each other to form a molecular layer The entire welding process is completed within 1 second, but the installation position of the ultrasonic transducer of the existing ultrasonic copper tube cutting and sealing machine is not ideal, resulting in the inability of the longitudinal wave energy of the ultrasonic vibration to be effectively converted into the welding head. The frictional energy acts on the metal surface to be welded, and the utilization rate of the energy is improved based on the above problems in this case
