Referring to fig. 2 to 5, the present embodiment is different from the previous embodiment in that the first internal corner 101 includes a mold plate 101a and a cavity 101b, the cavity 101b is surrounded by the mold plate 101a, the first connecting member 200 is embedded in the cavity 101b, the mold plate 101a is formed by extrusion molding, and the cavity 101b is left inside.

One end of the first internal corner 101 is provided with a chamfer A, the first internal corner 101 and the second internal corner 102 have the same structure, and the first internal corner 101 and the second internal corner 102 are obtained by cutting on the basis of an extruded section, wherein the chamfer is 45 degrees, and the first internal corner 101 and the second internal corner 102 are butted at the chamfer, so that the first internal corner 101 and the second internal corner 102 are perpendicular to each other to form an L shape with two equal sides.

The first connecting piece 200 comprises a first cross arm 201 and a second cross arm 202, and the first cross arm 201 and the second cross arm 202 are vertically connected; first cross arm 201 is connected to first internal corner 101 and second cross arm 202 is connected to second internal corner 102.

Further, the whole three-dimensional frame structure who takes the cavity of first connecting piece 200, its usable friction stir welding's mode is connected and is consolidated, and its welding temperature is much lower than the electric fusion welding, and welding thermal stress is little, and work piece non-deformable, and current stamping plate structural thickness is too low, can't utilize friction stir welding's mode to weld, and it can only use traditional electric fusion welding, produces various defects easily.

The first cross arm 201 comprises a peripheral plate 201a and an inner cavity 201b arranged on the inner side of the peripheral plate 201a, and a reinforcing strip 201c is arranged in the inner cavity 201 b; it should be noted that the first cross arm 201 and the second cross arm 202 are identical in structure and are symmetrically arranged.

The first cross arm 201 is used for reinforcing connection with the first internal corner 101, the same second cross arm 202 is used for reinforcing connection with the second internal corner 102, the existing connection structure with the stamping plate is too weak, the bearable stress is small, a new welding mode, namely friction stir welding, can be adopted when the first connecting piece 200 is connected with the first internal corner 101 and the second internal corner 102, and the connected first connecting piece 200 plays a role in stress dispersion.

Further, the ends of the first and second internal corners 101 and 102 are further provided with a second connector 300, and the second connector 300 is connected with the first and second internal corners 101 and 102 by friction stir welding.

It should be noted that the second connector 300 is a structure for connecting the internal corner with other internal corners, is formed by die casting, and is disposed at the end portions of the first internal corner 101 and the second internal corner 102 by welding. The second connector 300 includes an end plate 301 and a welding portion 302 disposed at one side of the end plate, and it should be noted that the welding portion is a convex structure disposed at one side of the end portion 301, which increases the connection strength between the first internal corner 101 or the second internal corner 102 while increasing a small volume.

Note that the sectional shape of the end plate 301 coincides with the sectional shape of the cavity 101b, and the end plate 301 is fitted into the cavity 101 b.

The outer side of the end plate 301 is provided with a process groove 301a, the end plate 301 is provided with a first through hole 301b in a penetrating mode, the first internal corner 101 and other internal corners are connected with each other through the end portion 301, specifically, the internal corners connected with the first internal corner 101 pass through the first through hole 301b through bolts and are connected with each other through the bolts, and the process groove 301a can prevent the influence caused by thermal barrier contraction when in connection and enables the connection to be firmer.

Furthermore, the shaping plate 101a comprises a side plate 101c, a top plate 101d and a bottom plate 101e which are connected with two ends of the side plate 101c, the top plate 101d and the bottom plate 101e are both vertical to the side plate 101c, and one end of the top plate 101d is also provided with a vertical plate 101 f; the bottom plate 101e is provided with a second through hole 101e-1, and the vertical plate 101f is provided with a third through hole 101 f-1.

In the present embodiment, the first and second internal corners 101 and 102 are both formed by extrusion because of their simple structure and low economic burden by extrusion; the first connecting member 200 is made by die casting, which is used because the first connecting member 200 has a complicated structure and cannot be obtained by an extrusion molding method.

The pressure casting is a method for filling liquid or semisolid alloy into a cavity of a die-casting die at a high speed and solidifying and molding the alloy under high pressure, has the advantages of high productivity, high product dimension precision and the like, and the molding structure of the alloy can be complex to a certain degree.

The main difference between the friction stir spot welding and the conventional friction stir welding is that a stirring head of the friction stir spot welding does not need to move left and right after being pricked into a workpiece, a contact part of the workpiece to be connected and the stirring head generates friction heat to generate a plastic softening layer, and metals in the softening layer are fully mixed together under the action of rotation of the stirring head to realize solid-state welding of materials.

The existing stamping section bar can only form a simple structure, and the plate surface of the stamping section bar is thin, so that the stamping section bar can only be welded and connected by adopting the traditional electric melting welding mode, the power consumption is high, and the defects are easy to generate.

Example 3

The embodiment provides a new method for processing a reentrant corner structure, which specifically comprises the following steps:

adding a 6061 aluminum alloy extrusion material into a die, and manufacturing a first internal corner 101 and a second internal corner 102 in an extrusion forming mode; note that, in this process, by extruding an aluminum alloy into an elongated shape, cutting the elongated shape into the shape of the first inside corner 101 by cutting, and using it as the first inside corner 101 and the second inside corner 102, a reinforcing rib is left inside the side plate 101 c.

Adding liquid or semi-solid alloy into a die, and manufacturing a first connecting piece 200 and a second connecting piece 300 by adopting a die-casting mode;

the second connection member 300 is connected by friction stir welding or friction stir spot welding at the ends of the first and second inside corners 101 and 102, respectively.

Connecting the first and second inside corners 101 and 102 with the first connecting member 200 by friction stir welding or friction stir spot welding; in the embodiment, compared with the traditional capacitor welding mode, the friction stir welding or friction stir spot welding mode has the characteristics of extremely low energy consumption, environmental friendliness, small welding thermal stress, difficult deformation of workpieces and the like, the economic benefit is higher in the actual operation process, and the rigidity of the whole internal corner is stronger.

The traditional alloy end keel overall structure is generally formed by cutting an aluminum profile, the other end of the traditional alloy end keel overall structure is a punching plate, the size of a connecting end surface part between a first internal corner 101 and a second internal corner 102 of the traditional alloy end keel overall structure is small, meanwhile, the traditional alloy end keel overall structure is also a hollow structure, the traditional alloy end keel overall structure cannot be connected in a friction stir welding or friction stir spot welding mode, and only can be connected by adopting an electric fusion welding process, so that the connecting strength of the whole end keel is not enough, the whole end keel is easy to damage in a long-time use process, at the moment, due to the space limitation of the structure, the whole internal corner is difficult to further weld by adopting capacitance welding, the whole internal corner needs to be disassembled and replaced, and the cost is very high; if the traditional internal corner of the alloy wants to adopt a welding mode of friction stir welding or friction stir spot welding, an iron block needs to be additionally welded in the hollow inner cavity of the traditional internal corner of the alloy, and the processing and transportation cost is greatly increased.

Liquid or semi-solid state alloy can be with the independent integrated into one piece of second connecting piece 200 and the third connecting piece 300 of reentrant corner, and first reentrant corner 101 and second reentrant corner 102 pass through 6061 aluminum alloy extrusion material extrusion, first reentrant corner 101 and second reentrant corner 102 have been improved, and the intensity of second connecting piece 200 and third connecting piece 300 self, make its mode that can adapt to friction stir welding or friction stir spot welding, when partial structure takes place to damage, only need demolish the part that damages, reuse friction stir welding's mode to install, need not to change whole reentrant corner, very big reduction of cost.

The second connecting piece 200 and the third connecting piece 300 are manufactured by adopting an extrusion forming mode, so that the thicknesses of the peripheral plate 201 and the end plate 301 can be matched with the thickness required by friction stir welding, and the peripheral plate can be molded in the manufacturing process without the situation of difficult impact forging; the second connecting piece 200 and the third connecting piece 300 are formed by die casting, so that the thickness of the peripheral plate 201a and the thickness of the end plate 301 can be guaranteed, the quality of the whole structure body can be reduced as much as possible on the premise that the whole bearing effect of the internal corner is not influenced, then the external plate 201a, the end plate 301 and the welding part 302 are welded by friction stir welding, the whole rigidity of the internal corner is improved, and the service life of the external plate is prolonged.
