Abstract
The invention provides a combined tightly-pressing device for strip steel splicing welding. The combined tightly-pressing device comprises tightly-pressing structures and upper elastic plates. The twotightly-pressing structures are located at the ends of two pieces of to-be-welded strip steel correspondingly. Each tightly-pressing structure comprises an upper pressing plate and a lower pressing plate. Each upper pressing plate and the corresponding lower pressing plate are located on two opposite planes, namely the upper plane and the lower plane, of the corresponding piece of strip steel. The two upper elastic plates are located at the positions, on the upper surfaces of the two pieces of strip steel, between the two tightly-pressing structures, and each upper elastic plate is detachablyconnected with the corresponding upper pressing plate. The invention further provides splicing welding equipment and method for strip steel splicing welding. By means of the combined tightly-pressingdevice and splicing welding equipment and method for strip steel splicing welding, it can be guaranteed that in the welding process, the lower surfaces of the left strip steel and the right strip steel are flush with each other all the time; the misalignment phenomenon of the strip steels is effectively reduced; a space can be reserved above a welding seam area; a welding device can be arranged and maintained conveniently; and the combined tightly-pressing device and the splicing welding equipment are simple in structure, and the splicing welding method is easy to implement.
Description
technical field [0001] The invention relates to the field of welding, in particular to a combined compacting device, tailor welding equipment and method for strip steel tailor welding. Background technique [0002] In the continuous production line of strip steel, the strip splicing welder welds the front and rear coils of strip steel together to realize continuous production. If the quality of the weld seam is not good, it is easy to cause the weld seam to crack or even break the belt, which will have a significant impact on the efficiency of the production line. In actual production, it is found that whether the strips on both sides of the weld are misaligned has a great influence on the quality of the weld. Therefore, improving the misalignment of the strip during tailor welding can greatly improve the quality of the weld. The research found that the reasons for the misalignment of the strip steel are mainly due to the following points: the original shape of the strip st...
