Problems solved by technology

Electromagnetic riveting and friction stir riveting technology are emerging stable connection technologies for plates. When friction stir riveting is followed by rivet rotation welding, a raised structure will appear at the bottom due to deformation of the plate. Therefore, it is necessary to set a top mold at the bottom of the plate. , so that the bottom of the plate is kept flat or the raised structure forms a certain shape, but the forming speed and effect of the ordinary top die on the plate are far inferior to the forming effect of electromagnetic riveting, and these two riveting methods are usually used separately when used , can not be combined processing according to the needs

Embodiment 1

[0050] Please refer to the accompanying drawings, the present invention provides a technical solution: a plate composite forming processing equipment based on electromagnetic riveting and friction stir welding, including a frame and a workbench 102, the frame includes a base 1, and the top surface of the base 1 is evenly fixed There are a plurality of vertical support columns 101, and are fixedly connected to the bottom surface of the workbench 102 through the support columns 101. Two vertical support plates 103 are symmetrically fixed to the middle position of the workbench 102 on both sides of the frame, and the two Mounting seats 105 are fixed between the bottoms of the two support plates 103, and top plates 104 are fixed between the top surfaces. The top faces of the mounting seats 105 are provided with electromagnetic riveting mechanisms 3, and the bottom surfaces of the top plates 104 are provided with stir friction mechanisms, and one of them supports The middle part of ...

Embodiment 2

[0076] The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that the top inner side of the side block 201 is provided with plate grooves corresponding to the two sides of the first positioning plate 4, and the two sides of the first positioning plate 4 are slidably connected to the plate. In the groove, a threaded shaft 407 is respectively fixed in the middle of both sides of the first positioning plate 4, and a horizontal shaft groove is correspondingly provided on the side wall of the plate groove, and the outer end of the threaded shaft 407 protrudes from the shaft groove, and is sleeved with Nut 408.

[0077] The position of the inner side of the plate on the adjustment plate 206 is determined by the inner side of the positioning block 402 below the first positioning plate 4. When the position of the inner side of the plate 206 needs to be adjusted, the nut 408 is loosened and the first position is moved along the direction of th...

Abstract

The invention discloses plate composite forming processing equipment based on electromagnetic riveting and friction stir welding in the technical field of riveting equipment, which comprises a worktable, a mounting seat and a top plate, a movable screw and two positioning seats are arranged on the worktable, an electromagnetic riveting mechanism is arranged on the mounting seat, and a friction stir mechanism is correspondingly arranged on the top plate. A feeding assembly is arranged on one side of the friction stir mechanism. By cooperation of the stirring friction mechanism and the electromagnetic riveting mechanism, stable deformation locking structures are formed on the two sides of the bottom while a rivet and two plates are subjected to stirring friction solid-phase welding, and the plate riveting stability is improved; the protruding structures at the bottoms of the plates form an outer wrapping structure in a certain shape, and the problems of breakage and the like caused by the fact that the bottoms of rivets penetrate through the plates are solved; and riveting machining, feeding and discharging of the plate can be conducted at the same time through the two positioning bases, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of riveting equipment, in particular to a plate compound forming processing equipment based on electromagnetic riveting and friction stir welding. Background technique [0002] Riveting technology is a method of connecting two or more parts with one rivet, which has the advantages of easy operation, reliable connection strength and no pollution. The traditional riveting method mostly uses axial force to thicken the nail rod in the rivet hole of the part and form a nail head to form a connection between multiple plates. Electromagnetic riveting and friction stir riveting technology are emerging stable connection technologies for plates. When friction stir riveting is followed by rivet rotation welding, a raised structure will appear at the bottom due to deformation of the plate. Therefore, it is necessary to set a top mold at the bottom of the plate. , so that the bottom of the plate is kept flat or the rais...
