Abstract

The utility model relates to a thin wall metal pipe auto-welding device, belonging to the technical field of the metal plate reel pipe welding machinery. The utility model is composed of a welding pipe chucking mechanism, the supporting of a welding trolley, a running mechanism and a host machine seat. The utility model is characterized in that a welding mandrel 2 used for loading pipe blanks 17 and a cross beam 8 used for loading the welding trolley 9 are double supporting point mechanisms, and two transverse sides of the lower part of the welding mandrel 2 are provided with hydraulicoperated pressing plates 16 which can press the pipe blanks firmly and tightly. The utility model has the advantages of good rigidity of the machine, good welding quality, etc., and the utility model is especially suitable for welding the longer pipe blanks.

Description

The metal thin wall pipe automatic soldering device

The utility model belongs to metallic plate pipe crimping electroplating equipment wielding machine technical field, is specifically related to a kind of metal thin wall pipe automatic soldering device.

The bonding machine that adopts for the welding of metal plate coils tube seam both at home and abroad is cantilevered at present, resemble the appearance of radial drilling machine, promptly be on a big rocking arm, movably welding tractor to be installed, welding torch is equipped with in the bottom of dolly, the seam of welding torch being aimed at pipe crimping moves welding tractor, welds automatically.The shortcoming of this bonding machine is: welding tractor is adorned on the at one end unsettled rocking arm, this is for the bigger weld seam of length, because oversize its rigidity of rocking arm is just relatively poor, makes that the distance between welding torch and the pipe seam just is difficult to reach accurate requirement, will influence the quality of welding.In addition, prior art is also lacking effective safeguard measure aspect pipe is installed, and secondly, prior art has certain rigidity and intensity in order to guarantee machine, and then its size is huge, the structure heaviness.

The utility model purpose is in order to overcome the shortcoming that above-mentioned prior art exists, and a kind of new solution that is provided with supporting base at its crossbeam and welding mandrel two ends is provided.

The purpose of this utility model is achieved in that this machine is made up of the be installed supporting of mechanism, welding tractor and walking mechanism and main engine bed thereof of pipe, and (as Fig. 1-shown in Figure 4) is characterized in that:

-described pipe the mechanism that is installed, be to give the left end that core wire axle 4 cantilevers are fixed on bearing 3, welding mandrel 2 cantilevers that will be with cushion block 20 again are fixed on the right-hand member of bearing 3, be provided with simultaneously by hydraulic drive, can regulate the movable bearing support 18 of its fulcrum height, be provided with in two horizontal sides of the bottom of welding mandrel 2 and be shaped on the combined oil cylinder 14 that combines by several hydraulic jacks 15 in its chamber in the bottom of the right-hand member of welding mandrel 2.

But the supporting of-described welding tractor and walking mechanism thereof be with the bottom welding torch 13 is installed, up and down roller 12 is housed, the welding tractor 9 that drives move left and right by worm-and-wheel gear 7 be installed in top and the bottom be provided with raceway 23, about be provided with on the box-shaped beam 8 of slideway 24, but box-shaped beam 8 left and right sides two supports are on expansion bearing 6 of its height of up-down adjustment.

Advantage of the present utility model and good effect are:

(1) because welding tractor 9 that welding torch 13 is housed is to be contained on the box-shaped beam 8 that is being supported by expansion bearing 6 at two ends, so overcome the shortcoming of cantilever beam rigidity difference, can guarantee has spacing accurately between welding torch 13 and the seam 19, can guarantee the quality of weld seam.

(2) after pipe 17 is contained on the welding mandrel 2, can be compressed securely by the pressing plate 16 that hydraulic cylinder 15 drives, therefore can guarantee that the weldment quality is good by several.

(3) crossbeam 8 of welding mandrel 2 and installation welding tractor 9 has all adopted the two point supporting, therefore, except that the strength and stiffness that guaranteed machine, also can reduce the size and the weight of machine.

Embodiment:

With sheet metal give be rolled on the core wire axle 4 tubular, and spot welding tube seam by hand, the pipe 17 that to put postwelding again is sleeved on the welding mandrel 2 that is with cushion block 20, adjustment is aimed at the seam on the pipe 17 19 with welding torch 13 and groove 21, expansion bearing 18 is compressed by hydraulic drive and welding mandrel 2, handle assembled hydraulic cylinder 14 again pressing plate 16 is pushed down pipe 17 tightly, regulate the movable bearing support 6 that constitutes by wedge mechanism by handle 5 then, make and reach desired spacing between the seam 19 of welding torch 13 and pipe 17, turn on the power switch then, drive welding tractor 9 by worm-and-wheel gear 7 and on the raceway 22 of box-shaped beam 9, move, realize welding automatically.Be shaped on slideway 23 on the two sides of box-shaped beam 8, match, can guarantee the accuracy of welding tractor 9 move left and right with slideway on the welding tractor 9.

The power supply of bonding machine and hydraulic power unit are installed in the chamber of main engine bed 1 all.
