Problems solved by technology

Most of the existing friction stir welding equipment fixes the workpiece to be welded on the equipment workbench, and relies on the movement of the equipment workbench or the equipment spindle to realize the feed movement of the workpiece, thereby completing the welding process, which makes the welded workpiece The welding width is limited by the travel of the equipment, making it impossible to weld wide-format workpieces

Embodiment Construction

[0012] The invention provides a friction stir welding feeding device, so that the friction stir welding can realize the welding of ultra-wide workpieces. The device adopts lateral positioning to realize welding of super-width workpieces, and makes the workpiece abut against a side guide wheel for lateral positioning while the workpiece is fed along the welding direction.

[0013] refer to figure 1 , the workpiece 9 to be welded is placed on the work table 01 of the friction stir welding feeding device; the front end of the workpiece to be welded 9 is provided with a traction device 8 for pulling the workpiece forward, and below the workpiece to be welded The lower idler 1 is provided with a plurality of upper pressing rollers 3 parallel to the lower idler 1 above the workpiece 9 to be welded;

[0014] refer to figure 2 , on one side of the workpiece to be welded 9, there are also two side guide wheels 11, the angle between the axis direction of the lower idler 1 and the pul...

Abstract

The invention provides a friction stir welding feeding device. The device comprises a plurality of lower supporting rollers arranged in parallel below a workpiece to be welded, a plurality of upper compressing rollers parallel to the lower supporting rollers arranged above the workpiece to be welded, a drawing device used for drawing the workpiece to move and arranged at the front part of the workpiece to be welded, and a side pull guide also arranged on the work surface, wherein the included angle between the drawing direction of the drawing device and the axial direction of the lower supporting roller and at one side adjacent to the side pull guide is an obtuse angle. Because a dip angle is formed by the axial direction of the upper compressing rollers and the lower supporting rollers and the forward direction of the workpiece , a force which enables the workpiece to be welded to approach the side pull guide is generated and the welding of the wide-size workpiece is realized.

Description

technical field [0001] The invention relates to the technical field of friction stir welding, in particular to a friction stir welding feeding device. Background technique [0002] Since Friction Stir Welding (FSW) was invented by The Welding Institute (TWI) in 1991, due to its many application and economic advantages, such as smooth welds, no welding consumables, Small weldment stress, wide welding range, easy to grasp welding process, low welding cost, etc., have made friction stir welding have reached the level of large-scale and industrialized application in the manufacturing field, and have been used in shipbuilding, rail vehicle manufacturing, world aerospace manufacturing, The world's auto industry and other fields have achieved remarkable results. [0003] With the increasingly widespread application of friction stir welding, people continue to research and improve its process parameters and the shape of the stirring head. However, due to the limitations of the fric...
