Abstract
A welding torch spray nozzle for automatic welding of consumable electrodes belongs to the technical field of welding torch spray nozzles of automatic welding apparatus for the consumable electrodes protected by inactive or mixed gases. The spray nozzle is characterized in that a ring pipe is formed by an internal sleeve and an external sleeve; the ring pipe is sealed by baffles arranged at the two ends thereof; a water inlet pipe and a water outlet pipe are mounted on the ring pipe; and a partition board is fixed in the ring pipe formed by the internal and the external sleeves, and is positioned between the water inlet pipe and the water outlet pipe. The utility model has the beneficial effects that due to the rapid and efficient temperature reduction function of recirculated cooling water, the spray nozzle is always in a low temperature status, thereby avoiding welding splashes from adhering to the inner wall surface of the spray nozzle, saving the auxiliary time of welding in cleaning up the welding splashes on the inner surface of the spray nozzle, reducing the labor intensity of operators and improving the production efficiency.
Description
Technical field
The utility model belongs to inert gas or mixed gas protected consumable electrode automatic welding and connects in the equipment welding torch and use the nozzle technology field.
Background technology
Consumable electrode automatic welding torch is that a kind of inert gas or mixed gas protected consumable electrode automatic welding connect the welding torch in the equipment, uses rated current more than 1000A.After protective gas enters welding torch by the rectification chamber,,, thereby form inert gas or the mixed gas protected district isolated with air in the welding pool region surface finally by the nozzle ejection via current divider, protective sleeve.Consumable electrode automatic welding connects the welding torch that disposes on the equipment at present, and the cooling effect of its recirculated water is not obvious; Welding tip is in the condition of high temperature, and the spatter thing sticks on the inner wall surface of nozzle, need often stop welding operation and clear up, and has influenced welding efficiency.
The utility model content
The utility model provides a kind of consumable electrode automatic welding torch nozzle, and recirculated cooling water is lowered the temperature rapidly and efficiently, and nozzle is in low-temperature condition, need not clear up nozzle specially during welding operation, thereby improve welding efficiency.
The utility model is achieved in that by inner sleeve and outer sleeve forms ring pipe, the two ends of ring pipe are provided with baffle plate ring pipe are sealed, ring pipe is provided with water inlet pipe and outlet pipe, be fixed with dividing plate in the ring pipe of inner sleeve and outer sleeve composition, dividing plate is between water inlet pipe and outlet pipe.
The beneficial effects of the utility model are: be fixed with dividing plate in ring sleeve, because recirculated cooling water cooling effect rapidly and efficiently, nozzle is in low-temperature condition all the time, therefore, the spatter thing can not stick on the inner wall surface of nozzle, save the welding non-cutting time of nozzle clearing inner surface spatter thing, alleviated operator's labour intensity, improved production efficiency.
Description of drawings
Fig. 1 the utility model consumable electrode automatic welding torch structure of nozzle schematic diagram;
Fig. 2 is the side view of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, the consumable electrode automatic welding torch structure of nozzle is: the ring pipe of being made up of inner sleeve 4 and outer sleeve 5, the two ends of ring pipe are provided with baffle plate ring pipe are sealed, ring pipe is provided with water inlet pipe 3 and outlet pipe 1, be fixed with dividing plate 2 in the ring pipe of inner sleeve 4 and outer sleeve 5 compositions, dividing plate 2 is between water inlet pipe 3 and outlet pipe 1.
During automatic welding torch work, recirculated cooling water enters the annular cavity of nozzle from water inlet pipe 3, because stopping of dividing plate 2, recirculated cooling water can only flow to the other end in by the annular cavity between inner sleeve 4 and the outer sleeve 5, flow out from outlet pipe 1 then, thereby the heat that inner sleeve 4 outer walls absorb is absorbed the discharge welding torch by recirculated cooling water quickly and efficiently.
Claims (1)
1, consumable electrode automatic welding torch nozzle, comprise the ring pipe that inner sleeve (4) and outer sleeve (5) are formed, the two ends of ring pipe are provided with baffle plate ring pipe are sealed, ring pipe is provided with water inlet pipe (3) and outlet pipe (1), it is characterized in that: be fixed with dividing plate (2) in the ring pipe of inner sleeve (4) and outer sleeve (5) composition, dividing plate (2) is positioned between water inlet pipe (3) and the outlet pipe (1).
