[0050] Refer to Figures 1 to 6, an argon arc welding machine for steel beam processing is proposed, which is used to vertically weld steel plate 101 and steel plate 102, and then weld triangular stiffeners 103 to obtain a steel beam 1. It includes a first circulating chain 2 and a second circulating chain 3. The first circulating chain 2 and the second circulating chain 3 are arranged in a circulating and conveying manner, and are arranged vertically, with an interval space 4 formed therebetween; there are several first clamping members 5, which are arranged in a circular pattern on the first circulating chain 2 and are used to clamp steel plate 101 to keep it vertical; there are several second clamping members 6, which are arranged in a circular pattern on the second circulating chain 3 and are used to clamp steel plate 102 to keep it horizontal. And the height of the interval space 4 is configured such that when steel plate 101 and steel plate 102 are located in the interval space 4, steel plate 101 overlaps steel plate 102; the first argon arc welding head 7 is movably arranged on one side of the interval space 4 and enters the interval space 4 after moving, and welds steel plate 101 and steel plate 102 together.

[0051] In this embodiment, by setting the first circulating chain 2 and the second circulating chain 3, steel plate 101 and steel plate 102 can be automatically conveyed, reducing manual operation. Compared with the prior art where manual labor uses tools for clamping and welding, the processing method of the assembly line significantly improves the welding efficiency. The use of the circulating chain reduces manual operation and significantly improves the welding efficiency. By setting the first clamping members 5 and the second clamping members 6 on the first circulating chain 2 and the second circulating chain 3, the correct positions of steel plate 101 and steel plate 102 can be ensured, thereby improving the welding quality. The use of the clamping members ensures the accurate position of the steel plate and improves the welding quality. By setting the first argon arc welding head 7, the welding work can be automatically completed, further improving the degree of automation of welding.

[0052] Working principle: The first circulating chain 2 and the second circulating chain 3 are arranged in a circulating and conveying manner and are arranged vertically, and are used to automatically convey steel plate 101 and steel plate 102. The first clamping members 5 are arranged in a circular pattern on the first circulating chain 2 and are used to clamp steel plate 101 to keep it vertical, and the second clamping members 6 are arranged in a circular pattern on the second circulating chain 3 and are used to clamp steel plate 102 to keep it horizontal. After the circulating and conveying arrangement, steel plate 101 and steel plate 102 can overlap in the interval space 4 between the first circulating chain 2 and the second circulating chain 3, cleverly realizing the correct position of steel plate 101 and steel plate 102 before welding, ensuring that steel plate 101 and steel plate 102 overlap and are perpendicular to each other to achieve automatic welding. The first argon arc welding head 7 is movably arranged on one side of the interval space 4 and enters the interval space 4 after moving, and welds steel plate 101 and steel plate 102 together, ensuring the stable realization of automatic welding.

[0053] Further, it further includes a first feeding component 8. The first feeding component 8 is arranged above the first circulating chain 2 and includes an inclined feeding plate 801 which is located above the first circulating chain 2; a baffle plate 802 is located on one side of the inclined feeding plate 801. After the first clamp 5 clamps the first steel plate 101, the uppermost end of the first steel plate 101 is lower than the lowermost end of the baffle plate 802.

[0054] In this embodiment, by arranging the first feeding component 8, the first steel plate 101 can be automatically fed into the first circulating chain 2, reducing manual operation and further improving the automation degree of welding. By arranging the inclined feeding plate 801 and the baffle plate 802, it can ensure that the first steel plate 101 is accurately fed onto the first circulating chain 2, improving the welding efficiency. The inclined feeding plate 801 is located above the first circulating chain 2 and is used to guide the first steel plate 101 to slide into the first circulating chain 2. The baffle plate 802 is located on one side of the inclined feeding plate 801 and is used to block the position of the first steel plate 101 to ensure that the first steel plate 101 will not continue to move after being clamped by the first clamp 5. And the uppermost end of the first steel plate 101 is lower than the lowermost end of the baffle plate 802, so that after the first steel plate 101 is sent to the first clamp 5, the baffle plate 802 will not block the movement and transportation of the first steel plate 101. Therefore, it ensures that the first steel plate 101 is blocked by the baffle plate 802 to avoid tipping during feeding, and also ensures that the first steel plate 101 is no longer blocked by the baffle plate 802 after being clamped by the first clamp 5.

The first moving clamping member 503 and the first unlocking push block 505 respectively have a first inclined surface 506 and a second inclined surface 507, and the first inclined surface 506 abuts against the second inclined surface 507.

[0058] In this embodiment, by providing the first unlocking push block 505 and the inclined surface structure, the first steel plate 101 can be quickly unlocked, improving the unlocking efficiency. By providing the first unlocking push block 505 and the inclined surface structure, the first steel plate 101 can be automatically unlocked, further improving the degree of automation of welding.

[0059] Further, the second clamping member 6 includes a second main body 601 which is disposed on the second endless chain 3 and has a second clamping groove 602. Second moving clamping members 603 are movably disposed on both sides of the second clamping groove 602, and the two second moving clamping members 603 are used for clamping the second steel plate 102. One end of a second elastic member 604 acts on the second moving clamping member 603, and the other end acts on the second main body 601 to provide a force for the second moving clamping member 603 to clamp the second steel plate 102.

[0060] In this embodiment, by providing the second moving clamping member 603 and the second elastic member 604, the stable clamping of the second steel plate 102 in the second clamping groove 602 can be ensured, improving the reliability of clamping. By providing the second moving clamping member 603 and the second elastic member 604, the second steel plate 102 can be automatically clamped, further improving the degree of automation of welding.

[0061] Further, the second clamping member 6 further includes a second unlocking push block 605 which is slidably disposed within the second main body 601. The second moving clamping member 603 and the second unlocking push block 605 respectively have a third inclined surface 606 and a fourth inclined surface 607, and the third inclined surface 606 abuts against the fourth inclined surface 607.

[0062] In this embodiment, by providing the second unlocking push block 605 and the inclined surface structure, the second steel plate 102 can be automatically unlocked, further improving the degree of automation of welding.
