Abstract

The invention provides a small-diameter pipe extrusion and soldering sealing device. The small-diameter pipe extrusion and soldering sealing device is characterized in that a square soldering machine head driven by an air cylinder is matched with a unique soldering tool, so that extrusion and soldering sealing of a small-diameter pipe are achieved; a medium frequency inversion soldering power source can accurately, stably and reliably meet soldering parameters needed by extrusion and soldering sealing; an air path system provides adjustable air pressure needed by the soldering tool driven by the air cylinder; a control system based on a PLC guarantees logical accuracy and adjustment of parameters and programs of the device.

Description

technical field [0001] The invention belongs to the field of welding technology, in particular to a small-diameter pipe extrusion welding sealing device. The invention can realize small-diameter pipe extrusion, resistance spot welding, and finally realize sealing, and the outer envelope size of the sealing part is not larger than the diameter of the small-diameter pipe. Background technique [0002] Extrusion welding technology is essentially a special resistance welding technology, which is generally used to seal small diameter stainless steel pipes. In order to meet the needs of sealed gas containers, the United States proposed and studied the extrusion welding sealing technology. At present, this technology is mainly used in the sealing of certain small-diameter gas pipelines in nuclear energy and related fields in the United States. [0003] Extrusion welding sealing technology performs electric welding and sealing directly on the catheter. After the welding position i...
