Abstract
The utility model relates to a contact tube used for a filament submerged arc welding machine, comprising a central wire through hole which is matched with the welding wire in diameter; the wire feeding section of the central wire through hole is a conical shape which is gradually enlarged towards the wire inlet; and the external surface of the wire discharging section of the contact tube is also a conical shape which is gradually diminished towards the wire discharging end. In the utility model, the wire feeding section of the central wire through hole adopts the conical shape which is gradually enlarged towards the wire inlet, thus being beneficial for the welding wires to pass successfully and avoiding interference; and the external surface of the wire discharging section of the contact tube adopts the conical shape which is gradually diminished towards the wire discharging end so as to avoid the interference with the soldering flux, thus being beneficial to successful flow-down of the soldering flux.
Description
Technical field
The utility model relates to a kind of filament submerged arc welding machine, particularly a kind of ignition tip that is used for the filament submerged arc welding machine.
Background technology
Artificial welding efficiency is low, of poor quality, thus in recent years automatically weldering more and more favored, especially with submerged-arc welding for.Submerged arc welding machine has a variety of, especially with the filament submerged arc welding machine use the most general, but need the crin welding in some cases,, make it to be applicable to that the crin welding is with imperative so the filament submerged arc welding machine is carried out local flow improvement if crin submerged arc welding machine of special purchase will raise the cost greatly.
Summary of the invention
The utility model provides a kind of ignition tip that is used for the filament submerged arc welding machine for solving the technical problem that exists in the known technology, cooperates with the pinch roller after the filament submerged arc welding machine improves, can make the filament submerged arc welding machine not be only applicable to that fine wire welding connects and can be applicable to that crin welds.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of ignition tip that is used for the filament submerged arc welding machine, it is provided with the center silk rolling hole adaptive with gage of wire, silk rolling hole, described center go into silk section a taper shape for enlarging gradually towards filament inlet, the outer surface of described ignition tip wire vent section is towards the diminishing taper shape of wire outlet end.
Advantage and the good effect that the utlity model has are: the silk section of going in silk rolling hole, center adopts the taper shape that enlarges gradually towards filament inlet, help welding wire swimmingly by and do not interfere; The outer surface of ignition tip wire vent section adopts towards going out to hold diminishing taper shape, can avoid itself and flux hopper to interfere, and helps solder flux and successfully flows down.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the pressure roller structure schematic diagram that is used with the utility model;
Fig. 3 is the side view of Fig. 2.
Among the figure: 1, center silk rolling hole, 2, silk rolling hole, center go into silk section, 3, gathering sill, 4, chamfering, 5, steel wheel, 6, collets.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
For make model be LAE 800 automatic submerged arc welding machine (manufacturer: ESAB) can use crin to implement welding, need carry out two-part transformation to it:
1) transformation of ignition tip: the hole that welding wire is crossed at former ignition tip center is an aperture, and diameter is usually less than 2mm, and global shape is cylindrical.See also Fig. 1, silk rolling hole, improved ignition tip center 1 is a macropore, and greater than 4mm, concrete size is determined according to employed welding wire, and the silk section 2 of going in this hole is made as the taper shape that enlarges gradually towards filament inlet, can make like this welding wire swimmingly by and do not interfere phenomenon.The external surface shape of ignition tip wire vent section is changed into towards the diminishing taper shape of wire outlet end by cylindrical, can avoid itself and flux hopper to interfere, and helps flowing down smoothly of solder flux.The material of ignition tip is a red copper.
2) to fixing and compress welding wire, pinch roller that welding wire is played guide effect transforms, concrete theing contents are as follows of transforming: the gathering sill cross sectional shape in the middle of the former pinch roller is 1/2nd dovetail groove, this gathering sill structure makes welding wire contact for linear with gathering sill, welding wire very easily is stuck and causes blow-out, make the welding can not be continuous, poor welding quality.See also Fig. 2～Fig. 3, improved pinch roller gathering sill 3 cross sectional shapes are the circular arc greater than 1/2nd circles, and are respectively equipped with outside chamfering 4 at the maximum gauge two ends.In the present embodiment, gathering sill 3 cross sectional shapes are 2/3rds circular arc, and edge chamfer 4 is 30 °, and it is that face contacts that this gathering sill structure makes welding wire and gathering sill, and welding wire is stable, requirement on the gage of wire direction is reduced greatly, otherwise the tolerance of welding wire on diametric(al) just must be strict especially, if gage of wire has deviation just very easily to cause the welding wire stuck phenomenon slightly, causes the welding machine blow-out, cause welding discontinuous, poor welding quality.30 ° chamfering makes welding wire successfully enter gathering sill and does not interfere.Improved pinch roller and prior art something in common are: be made up of steel wheel 5 and collets 6, both are interference fit, and material is respectively 45# steel and bakelite.
