Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and more particularly, to a hemming welding equipment. Background Art

[0002] Steel grating is a grid grating commonly used as a trench cover plate, a steel structure platform plate, and a tread plate of a steel ladder; steel grating is made of flat steel arranged crosswise at a certain spacing and cross bars, and welded into an iron and steel product with square grids in the middle; after the flat steel and the cross bars in the steel grating are fastened, a hemming strip needs to be welded and fixed on the outer edge of the steel grating; currently, the welding of the hemming strip and the steel grating is completed by a welding machine assembly, and the specific welding process is as follows: first, the hemming strip is placed into the welding machine assembly manually, then the hemming strip is clamped by the welding machine assembly. At the same time, the hemming strip can be in contact with the first electrode group in the welding machine assembly to conduct electricity. Then, the operator holds the steel grating and inserts the rear end of the steel grating into the welding machine assembly, and makes the rear end of the steel grating abut against the front side of the hemming strip. Immediately afterwards, the second electrode group in the welding machine assembly can move downward and clamp the steel grating and then contact the steel grating to conduct electricity. Then, the welding machine assembly starts to weld the hemming strip and the steel grating, that is, when the current flows through the first motor group, the hemming strip, the steel grating, and the second electrode group, the welding of the hemming strip and the steel grating can be achieved; by repeating the above steps, hemming strips can be welded and fixed on each side of the steel grating; however, in the above process, the hemming strip used for welding with the steel grating is placed into the welding machine assembly manually, resulting in the disadvantages of troublesome welding of the hemming strip and the steel grating, low welding efficiency, and high labor intensity of the operator. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a hemming welding equipment, which can facilitate the welding of the hemming strip and the steel grating and improve the welding efficiency of the hemming strip and the steel grating.

[0004] The present invention provides a hemming welding equipment, including a frame and a feeding component, a material handling component, a welding machine component, and a clamping component connected to the frame; the feeding component is located on one side of the welding machine component and is used to convey hemming strips to the material handling component one by one, the material handling component is used to convey the hemming strips from the feeding component to the front side of the welding machine component one by one, the clamping component is located inside the welding machine component, and the clamping component is used to clamp the hemming strip from the material handling component and drive the hemming strip to move inside the welding machine component, so that the rear side of the hemming strip contacts the first electrode group in the welding machine component to conduct electricity; when the steel grating is inserted into the welding machine component from front to back and abuts against the front side of the hemming strip located in the welding machine component, the second electrode group inside the welding machine component moves downward and clamps the steel grating and then contacts the steel grating to conduct electricity, so that the steel grating and the hemming strip are welded.

[0005] After adopting the above structure, the edging strip for welding with the steel grating can be automatically fed into the welding machine assembly, that is, there is no need to manually place the edging strip into the welding machine assembly, which can facilitate the welding of the edging strip and the steel grating, improve the welding efficiency of the edging strip and the steel grating, and at the same time reduce the labor intensity of the staff.

The plurality of magnets (51) are arranged at intervals with a plurality of first electrodes in the first electrode group (41); after the driving unit drives the plurality of magnets (51) to move forward, the plurality of magnets (51) are used to magnetically attract the edging strip (6) from the material handling component (3); when the driving unit drives the plurality of magnets (51) to move backward, the plurality of magnets (51) are used to drive the edging strip (6) to move from front to back so that the rear side of the edging strip (6) abuts against and contacts the front end of the first electrode group (41) in the welding machine component (4) to conduct electricity.
