Abstract
The invention relates to a windproof nozzle for welding a double-layer gas shield, comprising a connecting sleeve (2), an inner nozzle (3), an outer nozzle (4), vent holes (5) and a current contact nozzle (6). The nozzle is characterized in that the current contact nozzle (6) and the inner nozzle (3) are fixedly connected; an annual die space (7) is formed between the current contact nozzle (6) and the inner nozzle (3), wherein one end of the annual die space (7) is closed and the other end is open; the outer nozzle (4) is fixedly connected with the current contact nozzle (6) through the connecting sleeve (2), and a die space (8) is formed between the current contact nozzle (6) and the connecting sleeve (2) as well as the outer nozzle (4) and the inner nozzle (3); and parts of the current contact nozzle (6), which are arranged in the annual die space (7) and the die space (8), are provided with vent holes. The double-layer gas shield is formed by CO2 gas in welding, thereby of the welding work can be smoothly done outdoors at high position above the ground when the wind speed is more than 2m/sec and crater can not be caused.
Description
Technical field
The present invention relates to a kind of welding equipment, especially relate to a kind of nozzle that welds usefulness.
Background technology
Welding is usually carried out outdoor, and the outdoor work that wind speed reaches more than the 2m/sec is more, and wind speed is when 2.5m/sec is above, and plain nozzle just has arc crater and taken place, and operation Influences on Wind Velocity aloft is with regard to easier generation arc crater.Patent 200620133644.9 relates to a kind of double layers of arc welding gun protecting spray nozzle.
Summary of the invention
The object of the invention provides a kind of reaching at wind speed and does not still have the windproof nozzle for welding double-layer gas shield that arc crater takes place more than the 2m/sec.
The technical scheme that the present invention is adopted for achieving the above object is:
A kind of windproof nozzle for welding double-layer gas shield, comprise joint sleeve, inner nozzle, outer nozzle, passage, ignition tip, it is characterized in that: described ignition tip is fixedlyed connected with inner nozzle, forms the annular die cavity that one one end seals, the other end is uncovered between ignition tip and the inner nozzle; Outer nozzle is fixedlyed connected with ignition tip by joint sleeve, forms a die cavity between ignition tip, joint sleeve, outer nozzle and the inner nozzle; Described ignition tip is equipped with passage in the part of annular die cavity and die cavity inside.
Described ignition tip is threaded with inner nozzle.
Described outer nozzle is threaded with ignition tip by joint sleeve.
The diameter of described ignition tip in annular die cavity is less than the diameter of ignition tip in die cavity.
Described joint sleeve is that insulating materials is made.
Between described inner nozzle and the ignition tip insulate in the coupling part.
The invention has the beneficial effects as follows: use CO2 gas to form double-deck gas shield in when welding, operation and aloft during operation out of doors, wind speed reach 2m/sec when above welding job can carry out smoothly, and can avoid taking place arc crater.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 structure chart of the present invention.
The specific embodiment
As shown in Figure 1, a kind of windproof nozzle for welding double-layer gas shield, comprise joint sleeve 2, inner nozzle 3, outer nozzle 4, passage 5, ignition tip 6, described ignition tip 6 is fixedlyed connected with inner nozzle 3, forms the annular die cavity 7 that one one end seals, the other end is uncovered between ignition tip 6 and the inner nozzle 3; Outer nozzle 4 is fixedlyed connected with ignition tip 6 by joint sleeve 2, forms a die cavity 8 between ignition tip 6, joint sleeve 2, outer nozzle 4 and the inner nozzle 3; Described ignition tip 6 is equipped with passage 5 in the part of annular die cavity 7 and die cavity 8 inside.Ignition tip 6 is threaded with inner nozzle 3.Outer nozzle 4 is threaded with ignition tip 6 by joint sleeve 2.The diameter of ignition tip 6 in annular die cavity 7 is less than the diameter of ignition tip 6 in die cavity 8.Joint sleeve 2 is made for insulating materials.Between inner nozzle 3 and the ignition tip 6 insulate in the coupling part.
The gas passage of nozzle inner nozzle and two paths of outer nozzle have been divided into; the gas flow of 1 layer of original set is divided into 1; 2 is two-layer; utilize the 1st layer of protective gas protection welding position and increase flow; utilize the 2nd layer of protective gas to stop the wind speed of outside, and then form protection the 1st layer of gas.Operation and aloft during operation out of doors, wind speed reaches the above work of 2m/sec can carry out smoothly.At the CO2 gas pressure is 1.5Kgf, and when flow velocity was 40l/min, the flow velocity of plain nozzle can reach 2.3m/sec, and when the sectional area of nozzle butt was reduced 1/2 times, the flow velocity of nozzle was 3.7m/sec.So the sectional area of nozzle is reduced, wind speed also arc crater can not occur when 4.5m/sec.
