Metal welding auxiliary pressing mechanism

Abstract

The utility model discloses a kind of metal welding auxiliary compression mechanisms, belong to metal welding device technical field. Including fixed pipe, welding pipe, support plate, support plate is equipped with the positioning cylinder for being positioned different diameter welding pipe and being provided with several openings;Positioning cylinder is hollow cylinder, several positioning cylinders are mutually sleeved;Support plate side surface is equipped with several insertion slots, positioning cylinder is inserted into insertion slot, and support plate is equipped with the fixed screw rod that can simultaneously fix all positioning cylinders;Air inlet pipe is connected on support plate, and air inlet pipe is inserted into the positioning cylinder of smallest diameter;Air outlet is opened on support plate, and air outlet is communicated with the positioning cylinder of smallest diameter. Through single fixed screw rod, all sleeve can be simultaneously disassembled or locked, compact structure. Through by air inlet pipe introduction, air outlet exhaust airflow path, air can be transported to form convection after welding. This significantly accelerates the heat dissipation in pipeline, solves the problem of slow cooling.
