Description
Technical field
The present invention relates to a kind of welding gun, relate in particular to a kind of welding gun of semi-automatic gas powder protection weldering.
Background technology
The welding gun structure of existing semi-automatic gas shielded arc welding comprises rifle body, gun body switch, ignition tip seat, ignition tip, gas flow guiding cover and the gas silk multiple tube that is made of metal wire-feeding pipe and snorkel.Its welding method is in welding process, to carry electricity, welding wire and protective gas by welding gun to the weld zone.This welding method carbon dioxide commonly used is as protective gas, and the droplet transfer mode of its welding process is generally bulky grain transition or short circuiting transfer, and welding process is splashed greatly, the situation of appearance of weld difference thereby cause.In order to improve this situation; application number provides a kind of welding method of gas powder hybrid protection for 200310122023.1 Chinese invention patent; so that when carrying electricity, welding wire and protective gas to the weld zone; conveying can reduce the mealy medicine that splashes and improve appearance of weld to the weld zone by snorkel, reduces the purpose that appearance of weld is splashed, improved to welding process thereby reach.But the welding gun of existing semi-automatic gas shielded arc welding, because the restriction of its gas silk multiple tube and ignition tip seat structure is unsuitable for carrying protective gas and mealy medicine to the weld zone simultaneously in welding process.
Summary of the invention
The present invention makes to the weld zone and carries the purpose of electricity, welding wire, protective gas and mealy medicine to be achieved simultaneously by the improvement to existing semi-automatic gas shielded arc welding welding gun structure.
The welding gun of semi-automatic gas powder protection weldering of the present invention comprises rifle body, gun body switch, ignition tip seat, ignition tip, gas flow guiding cover and by the metal wire-feeding pipe be sleeved on the gas silk multiple tube that the outer gas tube cell of metal wire-feeding pipe constitutes; The outer surface of described metal wire-feeding pipe is provided with plastic pipe sleeve, the top of described ignition tip seat is provided with powder storing chamber, the powder storing chamber upper end is provided with the external screw thread that connects the rifle body, the both sides of powder storing chamber are provided with radially gas powder guide hole, the bottom of described ignition tip seat is provided with the internal thread hole that connects ignition tip, the outer rim of internal thread hole is provided with the equally distributed axial gas powder guide hole of circumference, and the conical surface is processed in the junction of described powder storing chamber and internal thread hole.
Described axial gas powder guide hole has 3~10; Described radially gas powder guide hole has 2 at least; The outer shape of described ignition tip seat bottom is set to taper shape.
The invention has the beneficial effects as follows: make the burning of the welding wire, protective gas and the mealy medicine fellowship welding arc that are delivered to the weld zone, the transition and the appearance of weld process of welding wire molten drop; thereby obtain suitable arc performance and welding wire mode of metal transfer, and better appearance of weld quality.
