Description

Heat casing bonding machine

Technical field

The utility model relates to welding field more particularly to a kind of welding suitable for plastic conduits such as PE pipe, pvc pipes Heat casing bonding machine.

Background technique

In the project that some progress main body water supply, drainage system are constructed, need to use a large amount of water supplying pipe.Because welded tube takes With high, time-consuming for ring flange welding, scene laying difficulty is big, weight is very much not easily installed, needs manually mostly etc., in order to save into This, and convenient for being laid using existing landform, part pipeline is laid using PE pipe.

PE pipe connection generally use hot melt plane-welding and heat casing welding two methods one of.Due to construction Site contour height rises and falls greatly, and pipeline needs are bent with landform, and water supply elevation is higher, and the pressure born required for pipeline is big, Therefore Welded Joints require high.Easily openable interface when plane-welding connector pipe bending, hydraulic pressure also easily cause greatly joint broken, Since field maintenance butt welding difficulty is big, lead to late maintenance cost height.Casing welding point is not variable in pipe bending Shape cracking, high hydraulic pressure do not easily cause casing desoldering yet, are suitable for complicated landform, and the later period does not need to safeguard substantially, maintenance cost It is low.Therefore, on construction ground in the case where height big rise and fall, water supply line generally takes the mode of hot melt casing welding to carry out Connection.

There was only plane-welding machine currently on the market, without casing welding robot.When PE pipe hot melt casing welding at present A necessary human hand held heat melting device is in centre, each minimum two human hand helds PE pipe in left and right or connector progress sweat soldering, welding process Holding pipe people must firmly keep steady PE pipe and firmly hot melt device pushing pipe or connector, careless slightly to result in PE pipe or connector connects Mouth skew, causes interface to be difficult to dock, or even causes useless pipe, and welding difficulty is big, and manpower is difficult to continue too long, often to weld Connecing 2~3 connectors will rest.Welding takes time and effort, generates the useless more, unstable quality, working efficiency bottom, at high cost of managing.

Utility model content

The utility model in view of the above-mentioned problems, propose a kind of welding efficiency it is high, it is time saving and energy saving and be suitable for PE pipe, PVC The hot melt casing bonding machine of the welding of the plastic conduits such as pipe.

The technical solution that the utility model is taken is as follows: a kind of hot melt casing bonding machine, including rack, fixed mechanism, leads To mechanism and heat melting device；The guiding mechanism and fixed mechanism are mounted on the rack；The fixed mechanism includes the fixed dress of pipe fitting It sets and sleeve fixing device, is respectively used to fixed pipe fitting and casing, the pipe fixing device are connect with guiding mechanism, can pass through The position of guiding mechanism change pipe fixing device；The fixed device of described sleeve pipe is also connect with guiding mechanism, can pass through Guiding machine The position of structure change sleeve fixing device；The heat melting device is for heating pipe fitting and casing.
