Description

Technical Field

[0001] This invention relates to the field of steel structure fabrication technology, and in particular to a container corrugated plate welding device and welding method. Background Technology

[0002] The steel plates used for corrugated steel sheets in shipping containers are typically between 1.4mm and 1.8mm thick, which is standard container material. A typical corrugated steel sheet is made by welding together several standard corrugated steel sheets; for example, the roof of a 40-foot high cube container requires eight standard corrugated steel sheets. To ensure the structural quality of the container meets the IICL international standard (no light leakage, no water leakage, and intact doors and floor), the appearance and quality of the weld seams in the corrugated steel sheet assembly are crucial for ensuring the container's airtightness. However, currently, most container manufacturers use commercially available corrugated steel sheet welding equipment for assembly and welding. These devices are relatively complex in structure and have high procurement costs; furthermore, they suffer from low welding efficiency and require improvement in terms of convenience.

The semi-automatic trolley 15 forms a reciprocating linear motion on the semi-automatic trolley track 17. The gas-shielded welding torch 19 is adjusted by the welding torch adjustment device 18, which makes a reciprocating linear motion in the Y-axis and Z-axis directions, thereby adjusting the appropriate welding position of the gas-shielded welding torch 19.

[0051] The aforementioned container corrugated sheet welding device can ensure the appearance and quality requirements of the weld seam during the assembly welding process of container corrugated sheets, meet the quality requirements of single-sided welding with double-sided forming and weld seam sealing of container corrugated sheet assembly weld seams, and make the assembly welding work of container corrugated sheets more efficient and convenient.

[0052] Example 2:

[0053] The present invention also discloses a method for welding corrugated sheets for containers, based on the above-mentioned welding apparatus for corrugated sheets for containers, the method comprising the following steps:

[0054] Step S1: Place two corrugated plates on the feeding platform and, after aligning them, fix them together by spot welding. Specifically, first place two corrugated plates on the feeding platform, then align them, ensuring that the edges of the two plates are flush and without gaps. Then spot weld the two plates together with a welding gun, with a spot welding distance of 80mm per spot. After spot welding both plates, grind the spot weld seam smooth.

[0055] Step S2: Convey the two spot-welded corrugated plates toward the discharge platform so that the joint between the two corrugated plates is aligned with the center line of the copper busbar of the corrugated plate clamping device; convey the spot-welded corrugated plates toward the discharge platform so that the joint between the two corrugated plates is directly above the copper busbar of the corrugated plate clamping device; then manually fine-tune the relative position of the joint between the two corrugated plates and the copper busbar so that the joint between the two corrugated plates is aligned with the center line of the copper busbar of the corrugated plate clamping device.

[0056] Step S3: The wave plate pressure plate is driven to move downward by the lifting mechanism to press the wave plate; specifically, the wave plate pressure plate is driven to move downward by the cylinder and then press the wave plate.

[0057] Step S4: Adjust the position of the semi-automatic trolley on the automatic corrugated plate welding platform on the semi-automatic trolley track and adjust its straightness so that the semi-automatic trolley can move along the direction parallel to the butt joint of the two corrugated plates; in order to avoid the weld seam from being crooked during welding.

[0058] Step S5: Adjust the welding torch adjustment device so that the welding wire extending from the gas shielded welding torch is positioned directly above the butt joint of the two corrugated plates.

[0059] Step S6: Begin welding the butt joint of the two corrugated sheets. If using a YD-500FR power supply, adjust the current and voltage parameters to 120A and 18V respectively. Adjust the movement speed of the semi-automatic trolley to 40cm / min. After the butt joint is welded, use the lifting mechanism to move the corrugated sheet pressure plate upward to release the corrugated sheet and push the assembled corrugated sheet onto the discharge platform. Before this, the discharge platform needs to adjust the gap between the two discharge platform jigs according to the width of the corrugated sheet to ensure that the welded corrugated sheet does not deform due to its own weight. Then, begin splicing the third corrugated sheet until all the corrugated sheets of the container are spliced.
