The specific embodiment
Technical scheme provided by the utility model is at CO
2On the basic platform of protection weldering, provide reinforcing bar to regulate the spacing and device for fastening of adjusting that clamps; Also provide a kind of copper mold to solve the enclosed environment and the welding pool of welding protection gas.
The technical scheme that the utility model provides is by CO
2Protection welding machine, CO
2Gas cylinder, wire-feed motor, U-shaped copper mold (comprise U-shaped copper mold base and band CO
2The U-shaped copper mold top cover of the middle opening square hole of rubber tube) and regulate spacing and device for fastening constitutes.CO wherein
2All there is off-the-shelf hardware in protection welding machine, wire-feed motor market; The utility model provides reinforcing bar to regulate anchorage clip, CO
2The design of protection bit copper mould.Fig. 1 a-Fig. 1 f is the view of U-shaped copper mold base, has wherein shown bolt M6.Fig. 2 a-Fig. 2 d is the view of U-shaped copper mold caping, has wherein shown internal diameter 5mm copper pipe M1.Fig. 3 a-Fig. 3 b is a view of regulating spacing and device for fastening.
Reinforcing bar is regulated anchorage clip: be that reinforcing bar is regulated the spacing device for fastening of adjusting that clamps, it can clamp the reinforcing bar that needs butt welding in narrow and small position, and by regulating bolt, makes reinforcing bar centering.
CO
2Protection bit copper mould: the enclosed environment and the welding pool that form welding protection gas.
The reinforcing bar CO that the utility model provides
2The weldering jockey comprises CO as shown in Figure 4
2Gas cylinder 1, ventilation leather hose 2, CO
2Welding machine 3, sealing wire 4 is regulated spacing and fastener 7 and reinforcing bar 8.Ventilation leather hose 2 connects U-shaped copper mold and CO
2Gas cylinder 1, sealing wire connects CO
2Welding machine 3 and reinforcing bar 8, reinforcing bar 8 are arranged to be regulated on spacing and the fastener 7, and U-shaped copper mold 6 provides the enclosed environment and the welding pool of welding protection gas, and reinforcing bar 8 passes from U-shaped copper mold 6.Be with ceramic gasket on U-shaped copper mold 6 bases.
The U-shaped copper mold is that copper plate compacting or cathode copper are cast after a little processes; The copper mold size should with adapted by welding steel muscle diameter.A kind of copper mold only is used for a kind of diameter reinforcing bar welding, and the steel seal of suitable bar diameter is arranged on the U-shaped copper bed die, and the copper lid is standard member.The thickness of U-shaped copper bed die is about 18mm, and the thickness of copper lid is about 5-8mm.
Require the rebar surface of welding must be smooth (adopt reinforcing bar that the gas pressure welding cutter special cuts off, adopt the reinforcing bar of abrasive machine cut-out can directly use substantially), first wire brushing surface before the welding, the rust cleaning oil removing, with regulating spacing and device for fastening carries out fastening to neutralizing (design reinforcing bar gap is generally 10mm) to reinforcing bar, put U-shaped copper mold (the heat insulation porcelain pad of cover in the base, this heat insulation porcelain pad can be bought from market) back and regulate CO
