because the one end of fagging 26 towards carousel 21 slides in spout 211, when promoting the bag 251 inflation and make guide head 23 remove, guide head 23 drives fagging 26 through articulated rod 261 and outwards removes, when expanding, the one end that fagging 26 is located in spout 211 slides along with, at this moment, the one end that is located in spout 211 on the fagging 26 and the fagging 26 on with articulated rod 261 junction form two limit points, stress point, thereby in fagging 26 removal process, guarantee fagging 26 to be parallel to each other with guide rod 24 all the time, prevent fagging 26 only with articulated rod 261 interconnect, the atress, lead to fagging 26 to appear crooked in the in-process of expanding, influence the location to the flange when fagging 26 expandes, fixed effect, and then lead to welding precision low, the deviation is big, influence welding quality.
As an embodiment of the present invention, a positioning bag 25 is installed between the baffle 241 and the guide head 23, the positioning bag 25 and the pushing bag 251 are concentrically distributed, and the positioning bag 25 and the pushing bag 251 are communicated with each other through a communication pipe 252;
the outer diameter of the positioning bag 25 before expansion is the same as that of the guide head 23;
after the straight pipe section 51 is sleeved on the guide rod 24, the guide head 23 is located inside the straight pipe section 51, after the pushing bag 251 is expanded, the positioning bag 25 and the pushing bag 251 are communicated with each other through the communicating pipe 252, so that the positioning bag 25 is also inflated with gas to start to expand, meanwhile, after the positioning bag 25 is expanded, the outer side surface of the positioning bag 25 can contact the inner wall of the straight pipe section 51, so that the straight pipe section 51 is positioned by the positioning bag 25 to further ensure that the straight pipe section 51 is overlapped with the center line of the positioning rod, the straight pipe section 51 and the flange plate 5 are concentric, meanwhile, after the positioning bag 25 is expanded and contacts the inner wall of the straight pipe section 51, the straight pipe section 51 can be fixed through the positioning bag 25, and the phenomenon that the straight pipe section 51 slides on a V-shaped frame formed by the rollers 32 in the welding process, so that the seam between the straight pipe section 51 and the flange plate 5 deviates and gaps occur, welding precision is affected, welding quality is poor, and the use of the straight pipe section 51 after welding is affected.
As an embodiment of the present invention, the positioning bag 25 is fixedly installed on the side of the guide head 23 facing the baffle 241, and the positioning bag 25 and the pushing bag 251 are not in contact with each other;
because the positioning bag 25 is mounted on the guide head 23 and the pushing bag 251 is mounted on the baffle 241, when the positioning bag 25 and the pushing bag 251 are expanded, relative movement can occur between the positioning bag 25 and the pushing bag 251 in the axial direction, that is, the positioning bag 25 moves along with the guide head 23 towards the direction of the turntable 21, meanwhile, because the positioning bag 25 is in contact with the inner wall of the straight pipe section 51 after being expanded, when the positioning bag 25 moves along with the guide head 23, the positioning bag 25 can also generate acting force pointing to the turntable 21 on the straight pipe section 51, so as to ensure that the straight pipe section 51 is tightly attached to the flange plate 5, ensure that the straight pipe section 51 is tightly contacted with the flange plate 5, and the positioning is accurate, thereby improving the welding precision, reducing the deviation and ensuring good welding quality;
meanwhile, as the positioning bag 25 is an air bag, when the positioning bag 25 is expanded and contacts the inner wall of the straight pipe section 51 and the positioning bag 25 moves opposite to the guide head 23, the positioning bag 25 can deform to a certain extent, so that the guide head 23 is ensured to continue moving towards the direction of the turntable 21, and the problem that the guide head 23 cannot continue moving when the straight pipe section 51 contacts the flange plate 5 and cannot continue moving is avoided, and the guide head 23 drives the supporting plate 26 to move and the supporting plate 26 is expanded to position and fix the flange plate 5 is solved.
As an embodiment of the present invention, a pressure valve is installed on the connection pipe 252, and the pressure valve is opened when the pressure exceeds a preset value;
because the positioning bag 25 and the pushing bag 251 are connected with each other through the communication pipe 252, the pressure valve is installed on the communication pipe 252, so that after the pushing bag 251 is filled with gas and expands to a certain extent, the gas in the pushing bag 251 begins to enter the positioning bag 25, and the positioning bag 25 expands, so that after the positioning bag 25 contacts the inner wall of the straight pipe section 51, the expansion amplitude of the pushing bag 251 is relatively small, the distance that the guide head 23 moves towards the direction of the turntable 21 under the action of the pushing bag 251 after the positioning bag 25 contacts the inner wall of the straight pipe section 51 is reduced, the deformation degree of the positioning bag 25 is reduced after the straight pipe section 51 contacts the flange plate 5, and the positioning bag 25 is prevented from being deformed in a large size, so that the positioning bag 25 is damaged and aged;
meanwhile, after welding is completed, along with the pumping and discharging of the gas in the pushing bag 251 by an external gas source, the pressure in the pushing bag 251 is reduced, the gas in the positioning bag 25 is discharged similarly, the positioning and fixing of the positioning bag 25 to the straight pipe section 51 are released, the welded straight pipe section 51 is convenient to take down from the welding flange device, meanwhile, in practical use, two communicating pipes 252 are provided, two check valves in opposite directions are connected to the two communicating pipes 252 respectively, it is ensured that certain pressure needs to be kept when the positioning bag 25 is inflated, when the gas in the positioning bag 25 is discharged, the gas is smoothly and conveniently discharged, and the problem that the gas in the positioning bag 25 is difficult to discharge due to the action of the pressure valve is avoided, and the fact that a worker takes down the welded straight pipe section 51 from the welding flange device is influenced.
As an embodiment of the present invention, a restriction net 253 is embedded in a sidewall of the push bag 251;
because the limiting net 253 is embedded in the side wall of the pushing bag 251, when the pushing bag 251 expands, the diameter of the pushing bag 251 is limited by the limiting net 253 and cannot be increased, so that the pushing bag 251 can only expand along the axial direction, and further the guide head 23 is pushed to move, so as to drive the supporting plate 26 to expand, position and fix the flange plate 5, and ensure good welding quality;
meanwhile, the limiting net 253 embedded in the pushing bag 251 avoids the diameter change of the pushing bag 251 when the pushing bag 251 is expanded, so that the outer side surface of the pushing bag 251 contacts the inner side surface of the positioning bag 25, and when the guide head 23 moves, the pushing bag 251 and the positioning bag 25 move relatively, so that friction occurs between the pushing bag 251 and the positioning bag 25, and the service lives of the pushing bag 251 and the positioning bag are influenced.
As an embodiment of the present invention, a buffer layer is installed on the side of the supporting plate 26 far away from the guide rod 24, and the buffer layer is made of aluminum silicate cotton or ceramic fiber cotton;
when using, through the surperficial buffer layer of fagging 26, avoid fagging 26 direct contact and extrude the internal surface on the flange board 5, avoid fagging 26 to produce the damage to the internal surface of flange board 5, and simultaneously, because flange board 5 uses the electric welding to weld with the seam crossing of straight tube section 51, the temperature is higher during the welding, prepare the buffer layer through using aluminium silicate cotton or ceramic fibre cotton, improve the buffer layer to the tolerance of high temperature, when avoiding flange board 5 and straight tube section 51 welding, the high temperature that the welding produced produces the damage to the buffer layer on the fagging 26, lead to the buffer layer impaired.
The specific working process is as follows:
during welding, a worker places the flange plate 5 on the guide rod 24 and contacts the surface of the rotary table 21, the guide head 23 penetrates through a hole in the middle of the flange plate 5, the hinged supporting plate 26 is located in the hole of the flange plate 5, then the worker places the straight pipe section 51 to be welded on a V-shaped frame consisting of the rollers 32 on the mounting plate 31, and meanwhile, the worker pushes the straight pipe section 51 towards the mounting frame 2 until the straight pipe section 51 abuts against the flange plate 5;
at this time, the operator controls an external air source to inflate the push bag 251 from the air pipe 221, the through hole 22 and the connecting hole 222 through the controller, so that the push bag 251 expands and pushes the guide head 23 to move towards the direction of the turntable 21, and when the guide head 23 moves, the hinge rod 261 drives the supporting plate 26 to move towards the direction far away from the guide rod 24 along the radial direction, so that the supporting plate 26 contacts and presses the inner side surface of the flange plate 5;
then, the worker adjusts the height of the lifting rod 4 through the controller to enable the welding gun 41 to be aligned to the joint of the straight pipe section 51 and the flange plate 5, and then the worker starts the motor 33 through the controller to enable the motor 33 to drive the roller 32 to rotate to start welding;
after welding, the worker raises the lifting rod 4 through the controller to drive the welding gun 41 to be far away from the welding position, and simultaneously, an external air source is used for pumping out and discharging the gas filled into the pushing bag 251 through the controller, so that the pushing bag 251 is shrunk, the pushing bag 251 does not push the guide head 23 any more, the supporting plate 26 does not extrude the inner side surface of the flange plate 5 any more, and the welded straight pipe section 51 is convenient to take down;
meanwhile, the support frame 3 and the lifting rod 4 are both electric telescopic rods; meanwhile, a rubber layer is covered on the surface of the roller 32;
because the baffle 241 has magnetism, the guide head 23 is subjected to the magnetic attraction of the baffle 241, and the guide head 23 is ensured to be positioned close to the baffle 241 on the guide rod 24;
because one end of the supporting plate 26 facing the rotating disc 21 slides in the sliding groove 211, the supporting plate 26 is always parallel to the guide rod 24 in the moving process of the supporting plate 26;
after the pushing bag 251 is expanded, because the positioning bag 25 and the pushing bag 251 are communicated with each other through the communicating pipe 252, the positioning bag 25 is also inflated with gas to start to expand, and meanwhile, after the positioning bag 25 is expanded, the outer side surface of the positioning bag 25 contacts the inner wall of the straight pipe section 51 to position and fix the straight pipe section 51;
when the positioning bag 25 and the pushing bag 251 are expanded, the positioning bag 25 and the pushing bag 251 can move relatively in the axial direction, and meanwhile, as the positioning bag 25 is expanded and contacts the inner wall of the straight pipe section 51, when the positioning bag 25 moves along with the guide head 23, the positioning bag 25 can also generate acting force which points to the rotary table 21 on the straight pipe section 51;
a pressure valve is arranged on the communicating pipe 252, so that after the push bag 251 is filled with gas and is expanded to a certain extent, the gas in the push bag 251 starts to enter the positioning bag 25, and the positioning bag 25 is expanded;
because the limiting net 253 is embedded in the side wall of the pushing bag 251, when the pushing bag 251 is expanded, the diameter of the pushing bag 251 is limited by the limiting net 253 and cannot be increased, so that the pushing bag 251 can only be expanded along the axial direction, and the guide head 23 is further pushed to move;
when using, through the buffer layer on fagging 26 surface, avoid fagging 26 direct contact and extrude the internal surface on the flange board 5, simultaneously, because the seam crossing of flange board 5 and straight tube section 51 uses the electric welding to weld, the temperature is higher during the welding, prepares the buffer layer through using aluminium silicate cotton or ceramic fiber cotton, improves the buffer layer to the endurance capacity of high temperature.
