Embodiment 1

[0034] Such as figure 1 shown.

[0035] A method that can make full use of friction stir welding materials. While completing friction stir welding, a brand new part is manufactured by using the material extruded by the stirring head, so as to achieve the dual purpose of obtaining welding plates and new parts in one friction stir welding. Specific steps are as follows:

[0036] First, use the clamps on the friction stir welding backing plate to fix the plates to be welded by friction stir welding; the clamps set around the backing plate are adjustable, and the clamps are placed on both sides of the backing plate to prevent excessive deformation of the plates during processing. The backing plate is steel plate, titanium alloy plate, tungsten alloy plate or molybdenum alloy plate. Such as figure 1 shown.

[0037] Secondly, a molding die is set at the end of the welding seam path, and the mold is fixed, and the feed port of the mold is opposite to the welding seam; the molding...

Embodiment 2

[0041] Such as Figure 2-4 shown.

[0042] A device that can make full use of friction stir welding materials. When the friction stir welding is completed, the material extruded by the stirring head is used to manufacture parts. The device uses the clamp 3 on the friction stir welding backing plate 2 to fix the friction stir welding plate 1 ,Such as figure 2 , 3 And set a set of specific forming molds 5 at the end of the welding seam path, place the plate to be welded on the fixture 3 to fix it, when the stirring head rotates and extends into the seam of the plate to be welded, the temperature of the plate is raised and softened, The extrusion process of the stirring head causes the end of the plate to deform, and a bulge appears. The bulge is squeezed into the forming die 5 at the end, and finally the welded plate 1 and the processed part 7 are obtained by cutting and grinding, such as Figure 4 . In order to facilitate demoulding, the forming mold 5 can be designed as a...

Embodiment 3

[0046] Such as Figure 5-7 shown.

[0047]A device that can make full use of friction stir welding materials, which includes a special mold 5 arranged at the end of the backing plate center direction; as Figure 5 , 6 As shown, the steel backing plate 2 (also can be titanium alloy plate, tungsten alloy plate, molybdenum alloy plate and other metal material plates), such as Figure 5 As shown, the size of the backing plate 2 is 800mm×400mm×30mm; the diameter of the stirring head is 5-100mm; there are adjustable clamps 3 around the backing plate 2, which are placed on both sides of the backing plate to prevent excessive deformation of the plate during processing.

[0048] Such as Figure 5 shown. Before the friction stir welding, place the 3.2mm thick 2024 aluminum alloy plate 1 to be welded on the backing plate 2, and adjust the clamp 3 to clamp the plate so that the end of the joint is aligned with the mold 5, and the mold 5 is a rectangle inside The concave mold of the g...

Abstract

A method and device capable of sufficiently utilizing a friction stir welding material are characterized in that the device is composed of a special mold arranged at the end of the center direction ofa base plate, the base plate and adjustable fixtures. In the friction stir welding process, when a stirring head moves to a welding terminal part, an expansion part occurs, an expansion part materialis squeezed into the mold to be formed, the tail end of a plate material is cut and polished, and finally, a welded plate material and a machined part are obtained.

Description

technical field [0001] The present invention relates to a method and device that can make full use of friction stir welding materials, especially a method and device for friction stir welding that can use materials extruded by a stirring head to manufacture parts while completing friction stir welding. The use of the method and the device increases the utilization rate of materials while ensuring the quality of the friction stir welding, and improves the economic performance. Background technique [0002] Friction stir welding (FSW) is a new solid-phase joining technology invented by The Welding Institute (TWI) in 1991 (US 5460317). FSW uses frictional heat as the welding heat source. In the FSW welding process, a cylindrical stirring head is inserted into the joint of the workpiece. Through the high-speed rotation of the stirring head, it rubs against the material of the welding workpiece, so that the material temperature at the joint Elevate and soften, and complete the w...
