Abstract
The invention discloses a water cooling device for arc skin longitudinal joint friction stir welding. The water cooling device is mainly composed of an arc plate, a cushion plate, plugging blocks, steel tubes and sealing plates. A skin is installed on the arc plate, the arc plate is provided with a groove, the cushion plate is installed in the groove in the arc plate, the cushion plate is connected with the arc plate, multiple T-type grooves are formed in the cushion plate, the steel tubes are inserted into the T-type groove and plugged through the plugging blocks, and the sealing plates are installed on the T-type grooves. The surface arc radius of the arc plate is the same as the inner diameter of the skin. The number of the T-type grooves is three. The water cooling device for the arc skin longitudinal joint friction stir welding is simple, practical, convenient to implement and particularly suitable for the friction stir welding performed on a skin longitudinal joint, and not only meets the requirement for back rigid supporting in the process of friction stir welding performed on the skin, but also improves the temperature field of the bottom of the skin weld joint, so that the skin is rapid and convenient to detach, and meanwhile service life of the water cooling cushion plate device is prolonged.
Description
Technical field
The invention belongs to cooling device, be specifically related to a kind of water cooling cushion panel assembly of arc covering longitudinal joint friction stir welding.
Background technology
Friction stir welding is a kind of solid phase interconnection technique of green, compares with traditional melting welding, has welding deformation little, pollution-free, and weld seam there will not be the common defects of melting welding such as crackle, undercut, is particularly suitable for the welding of aluminium alloy.At present, the docking longitudinal joint of the aluminum alloy arc-shaped covering of space flight type product generally adopts friction stir welding to be shaped, yet, during arc covering longitudinal joint friction stir welding, the back of weld seam must adopt the arc backing plate of rigidity to support, the quality of guarantee weld seam, in addition, the heat that covering produces when welding for a long time can conduct to backing plate, the temperature of backing plate is raise, the backing plate surface that the plasticizing metal of covering weld seam bottom and temperature are higher is pasted, and causes covering to disassemble from backing plate very difficult.
Summary of the invention
For the deficiencies in the prior art, when object of the present invention will provide a kind of arc covering longitudinal seam welding exactly, back obtains rigid support, can reduce the temperature that soldered is low, prevents from pasting arc covering longitudinal joint friction stir welding water cooling plant with backing plate bottom covering weld seam.
The object of the present invention is achieved like this: a kind of arc covering longitudinal joint friction stir welding water cooling plant, mainly by arc, backing plate, plugging block, steel pipe and shrouding, formed, covering is arranged on arc, arc is provided with groove, and backing plate is arranged in the groove on arc, and backing plate is connected with arc, backing plate is provided with a plurality of T-shaped grooves, steel pipe is inserted in T-shaped groove, and by plugging block shutoff, the top of T-shaped groove is provided with shrouding.The surperficial arc radius of arc is identical with the internal diameter of covering 6.T-shaped groove is three.
Arc covering longitudinal joint friction stir welding water cooling plant provided by the invention, simple and practical, enforcement convenience, be specially adapted to the long friction stir welding of covering longitudinal joint, back rigid support while having met covering friction stir welding, also improved the temperature field of covering weld seam bottom, fast and easy while making covering dismounting, the service life of simultaneously having improved water cooling cushion panel assembly.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention.
Fig. 2 is partial enlarged drawing of the present invention.
The specific embodiment
Structure of the present invention as depicted in figs. 1 and 2, comprise arc 1, backing plate 2, plugging block 3, steel pipe 4 and shrouding 5, covering 6 is arranged on arc 1, arc 1 is provided with groove, backing plate 2 is arranged in the groove on arc 1, and backing plate 2 is connected with arc, and backing plate 2 is provided with a plurality of T-shaped grooves, steel pipe 4 is inserted in T-shaped groove, by the top of plugging block 3 shutoff, T-shaped groove, shrouding 5 is installed.
The surperficial arc radius of arc 1 of the present invention is identical with the internal diameter of covering 6, described backing plate 2 top processing T type grooves are three, in T-shaped groove, insert steel pipe 4, the degree of depth that steel pipe 4 inserts backing plate 2 length directions is about 30mm, by plugging block 3, carry out shutoff again, adopt manual argon arc welding to seal, then shrouding 5 is covered above the T-shaped groove of backing plate, again adopt manual argon arc welding to seal, guarantee that cooling water is water-tight while circulating in the T-shaped groove of backing plate, the upper surface flush of the basic and backing plate 2 of the upper surface of shrouding 5.Backing plate 2 is assembled in the groove of arc 1, adopt manual argon arc welding that backing plate and arc is spot-welded together, assembly is filled on longitudinal seam welding fixture, at 3 oral siphons of one end of assembly access, then pick out 3 outlet pipes at the other end of assembly, two halves covering 6 is contained on pallet device, the both sides of covering adopt the hydraulic pressure qin of longitudinal joint frock to compress, adopt stirring-head 7 to carry out the friction stir welding of covering longitudinal joint, before welding, pallet device is passed into water and carry out cool cycles.
