Description
Technical field
The present invention relates to a kind of welding protection instrument, particularly relate to a kind of welding oxygen-proof protecting device.
Background technology
Protection weldering is the abbreviation of gas shielded arc welding, is the class in electric welding, mainly contains argon arc welding and carbon dioxide gas arc welding.During welding, the temperature in weld seam molten bath is very high, and the mother metal of weld metal and weld seam periphery can have a strong impact on weld strength and welding quality, so need butt welded seam protection because of oxidation.
When welding, some wlding self can discharge protective gas, protection weld seam, anti-oxidation.But in the welding processes such as picture argon arc welding, need to provide protective gas, just can reach protected effect.In argon arc welding operating process, the safeguard measure taked is that welding gun provides protective gas and back of weld to add protective cover two kinds of modes.Common welding protection cover is by manually hand-held, and when welder welds, the trend with weld seam moves, in operation, and workman's fatiguability of hand-held protective cover and the human resources of at substantial.
Summary of the invention
The present invention, in order to overcome deficiency of the prior art, provides a kind of welding oxygen-proof protecting device.
The present invention is achieved through the following technical solutions:
A kind of welding oxygen-proof protecting device, comprises protective cover portion and clamping part, described protective cover has trachea, by air pipe sleeve on trachea, connects source of the gas, can for protection gas in protective cover, described protective cover portion comprises protective cover and journal stirrup, and journal stirrup is connected to protective cover both sides, and journal stirrup has circular hole, can overlap on slide bar on the holder portion, described clamping part comprises chuck A, chuck B, chuck C, chuck D and slide bar, chuck A, chuck D are at relative position, and through a slide bar between two chucks, in like manner, chuck B, chuck C are at relative position, and through a slide bar between two chucks, chuck A and chuck B is fixed together, chuck C and chuck D is fixed together, and the position of two slide bars is parallel to each other, described chuck there is grip block A and grip block B, grip block A there is screwed hole, the two ends of plate A are placed in respectively the grip block A on chuck A and chuck D, between grip block B, tighten the hold-down screw on grip block A, get final product fixed plate A, in like manner, the two ends of plate B are placed in respectively the grip block A on chuck B chuck C, between grip block B, tighten the hold-down screw on grip block A, get final product fixed head B, gap between plate A and plate B is weld zone, now protective cover is positioned at the back side of weld zone, in welding operation, protective cover covers weld seam, weld seam is among the protection of protective gas, the weld seam of the isolated condition of high temperature contacts with air, protection weld seam can be reached, the effect of anti-oxidation, described slide bar is through journal stirrup, and protective cover along sliding bar, before exceeding the protection domain of protective cover, can move protective cover to welding direction at weld seam, can continue to protect the weld seam welded.
As the preferred technical solution of the present invention, the length >=100mm of described protective cover, when the length of protective cover is too short, cannot protect just shaping weld seam and cooling in weld seam, just at shaping weld seam temperature more than 1000 DEG C, if run into air, be very easily oxidized; Meanwhile, the weld seam in cooling, due to the impact of cooling velocity, if withdraw protection zone immediately after appearance of weld, also can be oxidized, and therefore extends the length of protective cover to 100mm, can reach protect simultaneously shaping in weld seam and cooling in the double effects of weld seam.
As the preferred technical solution of the present invention, described protective cover is rectangle or ellipse.
Compared with prior art, the invention has the beneficial effects as follows: the present invention, by being placed between two parallel slide bars by welding protection cover, utilizing chuck protective cover to be clamped in the side of bevel for welding, is convenient to welding operation, effectively protects weld seam, prevent weld seam to be oxidized.
