[0006] Second, it transports and feeds the plate through the driving wheels. In actual use, the positions of the upper and lower pairs of driving wheels cannot be adjusted, so that it is impossible to ensure that there is sufficient pressure and friction between the upper and lower driving wheels and the plate. The conveying and feeding effect of the plate cannot be guaranteed
[0007] Third, during the welding process, the two butt plates do not have a pressing force pointing to the weld seam, which makes the welding effect not good

Abstract

The invention discloses bidirectional friction stir welding equipment suitable for butt joint of dissimilar plates, which comprises the dissimilar alloy plates to be in butt joint and a friction stir welding body, and further comprises a base plate, a material base, a conveying device, a motor and a transmission device, wherein the conveying device comprises a driving conveying roller and a driven conveying roller; a first rubber strip and a second rubber strip are arranged on the two conveying rollers respectively, a welding bin is fixedly connected to the base plate, a clamping plate is arranged in the welding bin; the transmission device comprises a transmission shaft and a driving bevel gear, the adjusting device comprises a track plate, an adjusting screw rod, an adjusting seat and a connecting plate, and the tensioning device comprises a tensioning roller and a guide roller. The bidirectional friction stir welding equipment has the beneficial effects that conveying and feeding of the plates are reliable, the upper sides and the lower sides of the butted plates are subjected to two-way welding, the problems of large upsetting force, incomplete back welding, root defects and the like are solved; in the welding process, the two plates have pressure pointing to the welding position, and the welding effect is improved.

Description

technical field [0001] The invention relates to plate butt joint equipment made of dissimilar alloy materials, in particular to a bidirectional friction stir welding equipment suitable for butt joint of dissimilar plate materials. Background technique [0002] Plates made of two different alloy materials are generally butt-jointed by welding. Compared with traditional gas shielded welding, friction stir welding, as a new solid-phase joining method, effectively overcomes the problems of aluminum alloy fusion welding joints. Pores, cracks and other defects, and has the advantages of small joint residual stress and deformation, environmental protection and no pollution. [0003] The patent publication number is: CN201410135852.1 Chinese patent discloses a friction stir welding device, which includes a magnetic adsorption type automatic trolley carrying platform and a friction stir welding mechanism; The size is no longer limited by the size of the machine tool, and the on-site...
