Abstract

The invention provides a small-diameter tube extrusion solder sealing executive device with the pressure balance function. According to the small-diameter tube extrusion solder sealing executive device with the pressure balance function, two clamping heads and two electrode tips are fixed to four quick-changing bases supported by insulating plates which are fixedly connected with air cylinders respectively through clamp nuts, the clamping heads and the electrode tips are driven by the four air cylinders respectively, each clamping head and a sealing cavity body are connected into a whole, a sealing cavity is formed after the two sealing cavity bodies close up, extrusion solder sealing of a small-diameter tube is achieved in the sealing cavity, the sealing cavity is tightly clamped by a clamp with a safety structure, the sealing cavity is sealed in the mode of combination among a high-pressure sealing cavity, an integrated rubber sealing gasket and a local Teflon sealing gasket, the requirement of the two electrode tips for movement is met through two conductive soft copper strips, gas supply is carried out on the sealing cavity through a high-pressure gas path system, and it is ensured that balance between the internal pressure and the external pressure of the small-diameter tube in the welding process.

Description

technical field [0001] The invention belongs to the field of welding, and in particular relates to a small-diameter pipe extrusion welding sealing actuator with a pressure balance function. The invention can realize the extrusion welding sealing of the pressure-filled small-diameter pipe in the pipe. Background technique [0002] In the process of pressing the small-diameter tube in the extrusion-welded tube under normal pressure, the welding point of the small-diameter tube is melted and softened due to the discharge of the electrode. operator injury. At present, there is no report on extrusion welding of small-diameter tubes filled with pressure in the tube. Contents of the invention [0003] The object of the present invention is to provide a small-diameter pipe extrusion welding and sealing execution device with a pressure balance function. The feature of the invention is that by establishing a sealing cavity, the inner and outer pressures of the small-diameter tub...
