Abstract
The utility model discloses a kind of hand-held type oxy-acetylene blowpipe, it includes torch body, the clip being placed on torch body and the handle being welded and fixed with clip, it is obliquely installed between handle one end and clip face, connection through hole is provided with the flanging of clip, be fixed on clip on torch body by the fastener in connection through hole.Welded using hand-held type oxy-acetylene blowpipe of the present utility model, operation is light, can preferably reduce the weld defect such as burn-through, lack of penetration, undercut, steady quality, while improve production efficiency.It is particularly well-suited to the oxy-acetylene welding of the relatively thin part such as aluminium alloy.
Description
Technical field
The utility model is related to a kind of welding torch, more particularly to a kind of hand-held type type oxygen-acetylene welding torch.
Background technology
During the relatively thin parts such as oxy-acetylene welding aluminum alloy, welding torch should constantly with Part temperature with the angle of piece surface
Height be adjusted at any time, the angle of welding torch and weldment is generally 10 ° -45 °, and weldment is thinner, thermal conductivity and fusing point are lower, weldering
The inclination angle of torch should be smaller, has disperseed flame, conversely, then using larger angle of inclination, flame is more concentrated.Welding torch inclines
Rake angle will be changed as the case may be in welding process, usually because common type oxygen-acetylene welding torch is inclined in actual production
Angle change misoperation produces the weld defect such as burn-through, undercut, lack of penetration.
The current actually used type oxygen-acetylene welding torch of welder is usually portable, and this portable torch operation is special to be taken
Strength, low production efficiency；The angle change of welding torch is slow, so that easily cause the welding such as burn-through, lack of penetration, undercut lacking
Fall into.
Accordingly, it would be desirable to design a kind of type oxygen-acetylene welding torch for being easy to operation solve the above problems.
Utility model content
The utility model provides a kind of light hand-held type type oxygen-acetylene welding torch, and this welding torch can solve portable oxy-acetylene
Torch operation is especially hard, operation angle change is slow and low production efficiency problem, can preferably reduce weld defect,
Ensure Product jointing quality.It is particularly well-suited to the oxy-acetylene welding of the relatively thin part such as aluminium alloy.
In order to solve the above technical problems, a kind of hand-held type type oxygen-acetylene welding torch of the present utility model, it include torch body,
The clip being placed on torch body and the handle being welded and fixed with clip, are obliquely installed between handle one end and clip, clip
Connection through hole is provided with flanging, be fixed on clip on torch body by the fastener in connection through hole.
Angle between the handle and clip is 60 °.
The material manufacture that the handle and clip choose aluminium alloy is formed.
Distance of the clip center away from the tip of torch body is 250 mm-300 mm.
Welded using hand-held type type oxygen-acetylene welding torch of the present utility model, operate it is light, can preferably reduce burn-through,
The weld defects such as lack of penetration, undercut, steady quality, while improve production efficiency.It is particularly well-suited to the relatively thin part such as aluminium alloy
Oxy-acetylene is welded.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the side view of clip and handle.
Wherein：1st, handle, 2, clip, 3, bolt, 4, torch body, 5, connection through hole, 6, tip.
Specific embodiment
In order to deepen to understanding of the present utility model, further is made to the utility model below in conjunction with embodiment and accompanying drawing
Describe in detail, the embodiment is only used for explaining the utility model, does not constitute the restriction to protection domain of the present utility model.
As illustrated in fig. 1 and 2, a kind of hand-held type type oxygen-acetylene welding torch of the present utility model, it includes torch body 4, is placed on weldering
Clip 2 in torch main body 4 and the handle 1 being welded and fixed with clip 2, are obliquely installed between the one end of handle 1 and clip 2, clip 2
Connection through hole 5 is provided with flanging, the internal clamp of through hole 5 is connected（Bolt 3）Clip 2 is fixed on torch body 4.This
Design causes that the hand-held welding torch of welding operation personnel is changed to hand-held type by portable.
For the ease of operating and mitigating weight, the material manufacture that handle 1 and clip 2 choose aluminium alloy is formed.
Handle 1 is held when welder operates, handle 1 and clip 2 pass through together with Tig Welding, handle 1 during welding
Angle is 60 ° between clip 2, and two connection through holes 5 of Φ 4mm are provided with the crimp of clip 2, and bolt 3 is used for logical by connection
Be fixed on clip 2 on torch body 4 by hole 5, according to operating personnel's operating habit, can move forward and backward clip 2 and adjust, clip
Distance of 2 centers away from tip 6 is typically about 250 mm-300 mm.
For the ease of operating and mitigating weight, the material selection LF2 rust-preventing aluminum alloy tubing of handle 1, pipe specification is Φ
20 mm, the mm-1.5 mm of tubing thickness 1, processing are pressed into elliptic cross-section, and length is 120mm-150mm；Clip 2 is chosen
LF3 rust-preventing aluminum alloy sheet materials, the mm-1.5 mm of thickness 1.0.
Weldment material：LF21 aluminum alloy materials, thickness=0.5mm, using neutral flame and leftward welding.When snapping, welding torch master
Body 4 uses larger angle of inclination（With the angle of part）, flame is more concentrated.The angle of inclination of torch body 4 is in welding process
In respective change is carried out according to the situation of change of specific weldment temperature, when weldment temperature is raised, for avoid burn, do not weld
Thoroughly, the weld defect such as undercut, promptly operation handle 1 makes the inclination angular strain of torch body 4 small to welder, disperses flame, weldering
Part temperature drop.
