Description

Technical field

The invention relates to the technical field of welding devices, specifically a fully automatic steel pipe welding device.

Background technique

As the name suggests, steel pipes refer to steel materials with hollow sections. In the process of industrial production and processing, it is often necessary to use a welding device to weld two steel pipes to extend the length of the steel pipes or to make the two steel pipes achieve a certain angle. Usually before welding, The steel pipe to be welded also needs to be cut and fixed so that the two sections of the steel pipe can fit better.

However, the traditional steel pipe welding device has a relatively single function. It cannot realize automatic docking, fixing and cutting of steel pipes. During operation, the staff needs to cut the two steel pipes to be welded into mirror-fitting sections in advance, and then put them together. The two cut steel pipes are fitted and fixed, and finally a welding gun is used to completely weld the welding seam of the two steel pipes. In this process:

It requires workers to use multiple sets of tools to operate, which requires a large amount of human labor, low efficiency, and low automation. It cannot adapt to the efficient production of modern industry. In addition, cutting and welding are highly dangerous, and frequent manual operations can easily increase the risk of workshop accidents. incidence;

Manual cutting is difficult to ensure the quality of the two sections, especially when two steel pipes need to be connected at a certain angle. Manual cutting can easily lead to inconsistent and uneven cut angles, which in turn affects the fit of the two sections and affects the steel pipe. Welding quality.

In view of this, we propose a fully automatic steel pipe welding device.

A welding method of a fully automatic steel pipe welding device according to any one of claims 1 to 8, characterized in that: two steel pipes to be welded are placed in two clamping assemblies (35) respectively, and the first The second motor (351) causes the output end of the second motor (351) to drive the bidirectional screw rod (352) to rotate, and the bidirectional screw rod (352) drives the first splint (353) and the second splint (354) to move simultaneously through thread transmission. Intermediate movement, after the two steel pipes are clamped and fixed, if the two steel pipes need to be welded at a certain angle, the first motor (21) needs to be started, and the output end of the first motor (21) drives one of the steering gears (2) Rotate, the steering gear (2) drives the other steering gear (2) to rotate in the opposite direction by the same angle through meshing, and the two steering gears (2) drive the guide through the first connecting platform (31) when rotating The table (32) rotates, the guide table (32) drives the sliding seat (33) to rotate, the sliding seat (33) drives the support frame (34) to rotate, and the support frame (34) drives the clamping assembly (35) to rotate. After the angle is adjusted, Start the second cylinder (41) and the two cutting motors (45). The two cutting motors (45) drive the two cutting knives (44) to rotate at high speed respectively. The output end of the second cylinder (41) drives the movable plate (42) Moving forward, the movable plate (42) drives the two baffles (43) to move at the same time, and then drives the two high-speed rotating cutting knives (44) to move forward at the same time. The two cutting knives (44) cut the two steel pipes respectively. , the cut waste material falls into the material receiving groove (61) on the support plate (6). After the cutting is completed, the two first cylinders (38) are started at the same time, and the output ends of the two first cylinders (38) drive the sliding The seat (33) moves to the middle, and then drives the two support frames (34) to move. The two support frames (34) drive the two cut steel pipes to move to the middle through the clamping assembly (35), so that the two cut surfaces fit together. Finally, start the third cylinder (53), the output end of the third cylinder (53) drives the first welding gun seat (55) to move downward, and the first welding gun seat (55) drives the first arc plates (59) on both sides of it Moving downward, the first arc plate (59) pushes the round rod (58), so that the round rod (58) moves toward the center of the rotating ring (52) along the second limiting groove (521), and the round rod (58) ) drives the second arc plate (510) to move during the movement. Since one end of the second arc plate (510) is limited by the second welding gun seat (57), it can drive the second welding gun seat (57) Move toward the center of the rotating ring (52) along the first limiting groove (522), causing the four welding gun holders to move toward the center of the rotating ring (52) at the same time, and driving the four welding gun bodies (56) to move at the same time. A second spring (551) and a buffer plate (552) are provided inside the welding gun seat, so that the four welding gun bodies (56) can contact the welding seams of the steel pipe at the same time, weld the welding seams, and then start the welding gun body (56) and the third motor (512). The output end of the third motor (512) drives the transmission gear (513) to rotate. The transmission gear (513) drives the rotating ring (52) to rotate through the teeth (514), and then drives the welding gun body (56 ) rotates to achieve continuous welding of the butt weld seam.
