Description

Technical Field

[0001] The present application relates to the field of welding technology, and in particular to a welding device for preventing stainless steel sheets from deforming. Background Art

[0002] Stainless steel is elastic. It can deform when subjected to external force and return to its original shape after the external force is removed, which shows that it has a certain elasticity. The elasticity of stainless steel mainly comes from its internal lattice structure and the physical properties of the material.

[0003] The elasticity of stainless steel can be measured by its elastic modulus, which describes the material's ability to resist deformation when subjected to external forces. Stainless steel has a high elastic modulus, which means it can maintain the stability of its shape when subjected to force. In addition, stainless steel is also very tough and will not break easily when impacted, which also increases its durability in practical applications.

[0004] In the process of welding stainless steel plates from flat plates into coils, due to the influence of the elastic force of the stainless steel plates themselves, the two ends of the stainless steel plate joints will warp outward, making it difficult to ensure that the parts that need to be welded are aligned, resulting in misalignment and affecting the welding quality.

[0061] In one embodiment, how to align the welding surfaces at both ends of the stainless steel plate.

[0062] Specifically, the driving motor 26 is started, and the driving motor 26 drives the reverse roller 221 to reverse and drives the forward roller 222 to rotate forward, so that the inner side of one end of the stainless steel plate 3 abuts against the reverse roller 221, and the outer side abuts against the reverse roller 243, and the inner side of the other end abuts against the forward roller 222, and the outer side abuts against the forward roller 246, and the reverse roller 221 reverses and drives one end of the stainless steel plate 3 and the forward roller 222 to rotate forward, and drives the other end of the stainless steel plate to approach each other along the reverse roller 243 and the forward roller 246, so that the connection of the stainless steel plate 3 to be welded is located between the reverse roller 221 and the forward roller 222;

[0063] At the same time, when both ends of the stainless steel plate 3 approach the raised portion 231 on the positioning plate 23, the stainless steel plate 3 will approach along the top of the raised portion 231, and the stainless steel plate 3 will press the positioning plate 23 downward, thereby driving the extension rod 233 to move downward, so that the friction block 2322 on the boss 2321 moves downward, and when the raised portion 231 on the positioning plate 23 is completely pressed into the workbench 21 by the stainless steel plate 3, the bottom surface of the friction block 2322 contacts the braking surface 271, generating friction, so that the reverse roller 221 and the forward roller 222 stop rotating, and when the drive motor 26 is turned off, the reverse roller 221 and the forward roller 222 can also be prevented from rotating;

When welding from top to bottom, since the reverse rotating roller 243 and the forward rotating roller 246 block the welding port 16 from welding the outer surface of the stainless steel plate 3, the reverse cylinder 241 and the forward cylinder 244 are controlled to retract, and the reverse rotating roller 243 and the forward rotating roller 246 move toward the outer end of the workbench 21.
