Description

Technical Field

[0002] The utility model relates to a metal pipe welding device for building construction, which is a device used for welding metal pipes during the process of building construction.

[0003] The existing metal pipe welding device usually directly places the pipe on the welding table, and then the staff uses a welding gun to weld the pipe.

The warping will also cause the welding point to tilt, resulting in the pipe to be more bent after welding, thereby affecting the subsequent use of the pipe. Therefore, we propose a metal pipe welding device for construction. Utility Model Content

At this time, the U-shaped frame 124 moves downward together, so that the transmission roller 241 contacts the surface of the pipe 13. At the same time, continuous pressing will cause the inner rod 251 to drive the protrusion 252 to squeeze the spring 1 253. At this time, the transmission roller 241 is in close contact with the surface of the pipe 13 under the action of elasticity, so that the pipe 13 can be pressed, which can reduce the situation that the pipe 13 is tilted, thereby improving the welding accuracy and reducing the problem of bending of the pipe 13 after welding.

A rectangular long plate 143 and two limiting rods 144 are fixedly connected to the side of the connecting rod 142 close to the placement table 11; the arc-shaped supporting block 141 is pulled outward, and the connecting rod 142 drives the rectangular long plate 143 and the limiting rod 144 to move together, so that the arc-shaped supporting block 141 can be extended.

[0029] The rectangular long plate 143 is arranged at the center of the connecting rod 142, and the two limit rods 144 are distributed on the front and rear sides of the rectangular long plate 143. The bottom of the arc-shaped support block 141 is fixedly connected with an arc-shaped frame 411, and one end of the bottom of the arc-shaped frame 411 is fixedly connected to the surface of the connecting rod 142.

[0032] A specific application of this embodiment is:

[0033] When in use, the two pipes 13 are placed on the two placing tables 11 respectively, and the opposite sides of the two pipes 13 are in contact, and then the electric push rod 123 is started to drive the outer rod 125 to move downward. At this time, the outer rod 125 will drive the U-shaped frame 124 to move downward together through the inner rod 251, so that the transmission roller 241 contacts the surface of the pipe 13. At the same time, continuous pressing will cause the inner rod 251 to drive the protrusion 252 to slide in the outer rod 125, thereby squeezing the spring 1 253. At this time, the transmission roller 241 is in close contact with the surface of the pipe 13 under the action of elasticity, and then the electric push rod 123 stops, and the pipe 13 can be pressed. Then the staff can use the welding gun to weld the two pipes 13 at the joint. When it is necessary to rotate the pipe 13, the motor 243 is started to drive the middle transmission roller 241 to rotate. Since the surface of the transmission roller 241 is uneven, the friction force can be increased, thereby smoothly driving the pipe 13 to rotate, and welding can be performed on other positions;

[0034] When the length of the tube 13 is long, the arc-shaped support block 141 can be pulled outward, and the arc-shaped support block 141 will drive the connecting rod 142 to move through the arc-shaped frame 411, and the connecting rod 142 will drive the rectangular long plate 143 and the limiting rod 144 to move together, so that the arc-shaped support block 141 can be extended. At this time, the longer tube 13 can be placed on the arc-shaped support block 141, so as to lift the tube 13 and play a good supporting role. When the rectangular long plate 143 moves, the spherical clamping block 452 will be pushed downward, and the telescopic rod 451 will slide in the fixed tube 145 and stretch the spring 2 453, so as to smoothly move the rectangular long plate 143. After the movement is completed, the rectangular long plate 143 will be fine-tuned so that the spherical clamping block 452 will pop into the spherical clamping groove 431, which can play a simple limiting and fixing role for the rectangular long plate 143 to avoid deviation.
