At present, the flange welding of building pipe pile end plates mainly adopts manual CO2 welding, which requires manual flattening, spot welding positioning, welding, turning over and re-welding.
The disadvantages of flange welding on the end plate of the artificial pipe pile are that the quality of the weld is unstable, the consistency of the weld is poor, the welding material is wasted, and the efficiency is low. Moreover, due to the poor welding operation environment, the wages of welders have increased rapidly year by year, and the staff mobility is not good. management!
Anjia has developed a fully automatic robotic welding line for pipe pile end plate flanges according to customer needs. It can automatically slice, seam weld, and automatically cut materials, completely replacing manual welding, and greatly improving the quality of pipe pile end plate flange welding. And efficiency.
I. Equipment working principle and mechanism description:
The equipment is based on two welding robots equipped with intelligent weld seam tracker, which automatically follows the seam, compacts, and welds on two sides, one long and one short two welds, and automatically unloads. In addition to manual winding, the entire process of fully automatic pipe pile end plate flange welding does not require personnel to participate.
The equipment is mainly composed of a segmentation mechanism, a roller line, a seam-stitching mechanism, a pressing mechanism, a welding robot, an automatic turning mechanism, an off-load loading mechanism, a cutting mechanism, a control system, an automatic gun cleaning, and welding dust removal.
1.Automatic feeder , consisting of frame, silo, jacking slicing, hydraulic station, slideway, detection sensor, etc., can adapt to 400 ~ 600 diameter pipe pile end plate flange automatically slicing into the drum line;
2. The automatic drum line is composed of a frame, a drum, an AC motor, a reducer, a sensor, a pushing cylinder, etc., and is responsible for pushing the flange of the pipe pile end plate to the transfer station on standby.
3. The transfer mechanism is composed of a lifting cylinder, a lifting guide, a clamping mechanism, a translation mechanism, etc., and is used to transfer the flange of the pipe pile end plate to be welded to the welding station.
4. The automatic compaction mechanism adopts servo or oil cylinder compaction to ensure the flatness of the welded front end surface of the pipe pile end plate flange.
5. Welding robot , adopting six-axis welding robot, equipped with digital inverter CO2 welding machine and welding seam tracker, can automatically adapt to changes in welding seam length, welding seam offset, and width of welding seam when welding of pipe pile end plate flange , And guide the welding gun to automatically adjust the position welding current and welding speed to achieve a perfect weld!
6. The transfer and transfer mechanism is composed of a clamping cylinder, a rotating cylinder, a buffer, a guide rail, the gear rack, a servo motor, etc., which automatically turns the flange on one side and moves it to the next station to weld the other side. .
7. The unloading mechanism adopts a three-axis handling module, which is responsible for putting the welded pipe pile end plate flange and a small number of out-of-tolerance unwelded parts into different silos, respectively.
8. The control system controls the sequence of actions of the actuators of the whole set of equipment. It consists of control box, PLC, touch screen, detection switch, etc. The main functions are as follows:
1) Set basic welding parameters, such as position, pressure, welding frequency, transfer speed, etc .;
2) Display and monitor basic welding parameters and key data of equipment operation, such as pressure, speed, output, etc., alarm and shutdown when exceeding limits to ensure welding quality;
3) Store multiple sets of welding specifications to facilitate quick call when welding different end plates.
9. Gun cleaning mechanism . When welding the flange of the pipe pile end plate, the robot welding gun can automatically perform slag cleaning, wire cutting and oil injection to ensure the continuous welding and quality of the welding seam.
10. Welding and dust removal equipment , automatically sucks welding smoke and welding dust to ensure that the environment in the working area meets environmental protection requirements.

The successful development and smooth commissioning of a fully automatic pipe pile end plate flange robot welding line has greatly improved the efficiency and quality of pipe pile end plate flange welding. Through expansion, it can also be combined with automatic flattening, automatic car outer circle, automatic drilling, tapping, countersinking, and fully automated production of the entire pipe pile end plate flange from hot coiling!
