Description

Technical Field

[0001] The invention relates to the technical field of steel cage welding, in particular to a rolling welding machine for automatic welding of steel cages. Background Art

[0002] Steel cage welding is a widely used equipment in the field of steel bar processing. It is used for the forming and welding of steel cages. The steel bars are wound and welded into a steel cage with a strong structure. The main bars of the steel cage are passed through the corresponding template circular holes on the fixed rotating disk and fixed in the corresponding holes of the mobile rotating disk. Then, the coiled bars are wound around the main bars through the rotation and movement of the fixed rotating disk and the mobile rotating disk, and then welded to form a steel cage with a strong structure. However, in use, there are the following deficiencies in welding: as a metal material, steel bar has a certain elasticity, so that there is a gap between the coil and the main bar. When the coil is wrapped around the main bar, a certain gap will be generated at the connection welding point. The gap will cause the effective cross-sectional area of ​​the weld to be reduced, such as lack of fusion, incomplete penetration, slag inclusion, etc., which will directly affect the quality of the finished product.

[0029] By operating the position of the adjustment block 52 on the movable arc block 51, a steel cage suitable for different diameters is selected. At the same time, after adjusting the angle of the fixed welding component 53, the angle of the fixed welding component 53 is fixed by rotating the fixing knob inside the fixing hole.

[0030] A cylinder 531 is provided at the end of the fixed welding component 53, and a laser welder 532 is fixedly connected to the output end of the cylinder 531.

The cylinder 531 on the welding mechanism 5 works to drive the laser welder 532 to descend.

[0033] Specific working principle; When in use, the device is placed in a suitable position and fixed, and then the main reinforcement is sent into the auxiliary tube 241 of the auxiliary component 24. It should be noted that when the main reinforcement is on the feeding device, the extrusion rod 292 needs to be misaligned and parallel to the ground before the main reinforcement can be sent from the auxiliary tube 241. Then the first drive motor 21 is started, and the first drive motor 21 drives the first matching tooth 22 to work, and the first matching tooth 22 drives the first matching roller 25 to rotate, and then wait until the extrusion rod 292 and the first hollow cylinder 272 are on the same horizontal line, and then the second main reinforcement can be delivered. When the main reinforcement After the feeding is completed, the coiled reinforcement is wound onto the main reinforcement, or the coiled reinforcement is fed into the main reinforcement. Then, the fifth driving motor 42 on the guide body 41 is started. At this time, the fifth driving motor 42 drives the fourth matching tooth 43 to work, so that the offset mechanism 3 starts to move forward. When the diameter of the main reinforcement is of a suitable radius, the front end of the main reinforcement is inserted into the opening of the circular array of the support disk 33. If the required diameter is larger, the second driving motor 284 can be started, so that the second matching tooth 283 drives the sixth matching tooth 281 to expand the expansion block 282 outward for a distance, and then the main reinforcement is passed through the matching hole of the support disk 33. Then Start the third drive motor 293 and turn off the second drive motor 284. When the third matching tooth 294 drives the two rotating arc bodies 291 to position the main rib, start the second drive motor 284 again and turn off the third drive motor 293. At this time, the fifth drive motor 42 stops working. When the movable arc block 51 moves to a suitable position, the fourth drive motor 533, at this time, the output rate of the first drive motor 21 is reduced, so that the first matching roller body 25 moves slowly. When the position of the welding mechanism 5 is inaccurate, it can be adjusted by adjusting the front and rear distance of the adjustment block 52 and rotating the fixed welding component 53 to adjust the angle, and then The laser welder 532 is fixed again, and the fourth drive motor 533 drives the guide component 536 to work. At this time, the guide component 536 pulls the first conductor 5361 to limit the sliding of the second conductor 5362 inside the limiting arc 535. Then the pulling block 5363 tightens the cross formed by the coil reinforcement and the main reinforcement. At the same time, the cylinder 531 on the welding mechanism 5 works to drive the laser welder 532 to descend, and at the same time, the cross gap is reduced again to perform welding. Then, the fourth drive motor 533 reverses and pulls out the first conductor 5361. After the welding is completed, the output end of the cylinder 531 retracts to complete this part of the welding process.
