Specific embodiment
For making the object, technical solutions and advantages of the present invention become more apparent, below in conjunction with specific embodiment, and reference
Accompanying drawing, the present invention is described in further detail.
The present invention is directed to problem on deformation when being welded between cathode steel bar as shown in Figure 1 and blast welding steel plate, if
Count one kind and rigidly fix fixture.It is the dimensional drawing of cathode steel bar as shown in Figure 2.Wherein, the length of described cathode steel bar is
2000mm, highly for 220mm about, thickness is 80mm；It is the dimensional drawing of blast welding steel plate as shown in Figure 3, described blast welding steel
The length of plate is 300mm, and highly for 220mm, described blast welding steel plate is welded by aluminium sheet and steel plate, between steel plate and aluminium sheet
There is steel al blasting weld seam, wherein aluminium plate thickness is 12mm, and steel plate thickness is 40mm.Fig. 4 is cathode steel bar and blast welding steel plate dress
Ligand sizes figure, two cathode steel bars are placed in parallel, centerline 207mm, and blast welding steel plate is apart from cathode steel bar end face
Apart from 20mm.Above-mentioned be only used for illustrate, the invention is not restricted to above-mentioned size and structure, actual size and structure need to be according to realities
Depending on the situation of border.
As shown in figure 5, the present invention proposes a kind of weld jig.Described weld jig includes：Fixture pedestal 1, fixture wedge
Son 2, anti-deformation plate 3 and welding backing frame 4.
Described fixture pedestal 1 is the benchmark of whole weld jig, relative with cathode steel bar for determining blast welding steel plate
Position.As shown in fig. 6, described fixture pedestal 1 is an axisymmetric welding structure, including：Benchmark frame 5, rigidity reinforced plate 6,
Hook-shaped seat 7, electrode holder frame 8, anti-deformation panel seat 9 and gasket base 10.
Described benchmark frame 5 and rigidity reinforced plate 6 are the main parts of described fixture pedestal 1.Described benchmark frame be one U-shaped
The entirety that plate and two corner brackets are welded.The both sides of U-shaped plate form two U-shaped frames, two cathode steels with two corner brackets respectively
Rod is placed in described U-shaped frame, and is clamped from the both sides of described U-shaped frame by 4 bolts, to ensure that in welding process, benchmark is steady
Fixed, position does not change.And due to benchmark frame 5 structural instability, poor rigidity, therefore it is welded with rigidity reinforced frame at its back side
6, mechanically deform and welding thermal deformation can be prevented.Cooperation between benchmark frame 5 and cathode steel bar will leave enough gaps, benchmark
The distance arriving cathode steel bar face inside the U-shaped frame of frame 5 is more than 5mm, can allow the position that cathode steel bar is installed and the later stage deforms
Deviation.
Additionally, the two of benchmark frame 5 U-shaped frame outermost lower ends are respectively welded a hook-shaped seat 7, for placing clamp wedge
Son 2, similar to hook, compact conformation is compact, but rigidity prevents Welding Angular Deformation enough for hook-shaped seat 7 profile.
The outermost of two described hook-shaped seats 7 is symmetrically welded with electrode holder frame 8, for clamping source of welding current ground wire.Hook-shaped seat 7
And thereon the electrode holder frame 8 that welds in both sides symmetrically relation, its symmetrical structure can prevent arc blow, improve welding matter
Amount.
Hook-shaped seat 7 obliquely downward is welded with anti-deformation panel seat 9, for placing anti-deformation plate 3.
Hook-shaped seat 7 bottom is provided with gasket base 10, for placing welding backing frame 4.
In sum, fixture pedestal is the core component of whole fixture.As weldment, each weld requires full weld,
Ensure sufficient intensity, note welding sequence and position, and ensure that welding must not deform.
Fixture chock 2 is also a weldment, by bolt, it is fixed together with aluminum steel explosion welding plate, insertion
Welding Angular Deformation is prevented in fixture pedestal.Its structure is as shown in fig. 7, be mainly welded by U-shaped frame 12 and voussoir 13.U-shaped
Frame 12 both sides respectively have two bolts to determine the position with aluminum steel explosion welding plate.Voussoir 13 is welded in U-shaped frame both sides, is inserted directly into
The surface of the hook-shaped seat 7 of fixture pedestal, leaves 0.1～0.2mm gap between the two, prevents U-shaped frame 12 in welding process
To both sides distending so as to reduce to the pressure of steel plate, lead to the overall angular deformation to cathode steel bar side of aluminum steel explosion welding plate.
Dismantle after additionally welding to be ensured terminates.
Anti-deformation plate 3 as shown in figure 8, its relatively simple for structure it is simply that making a call to two intersecting sizes not on one block of steel plate
The same hole, is shaped like calabash, therefore also referred to as anti-deformation plate.Its size is according to the chi of the anti-deformation panel seat of fixture pedestal
Very little, the plank set on anti-deformation panel seat 9 can be entered by the Assurance of Size of macropore, then moves down anti-deformation plate 3, relies on
The tight fit of aperture, can prevent welding process further from machinery, fixture pedestal and fixture chock distending laterally, protect
Card pressure is enough it is ensured that frictional force can prevent Welding Angular Deformation.
Welding backing frame 4 is as shown in figure 9, in order to avoid itself and welding rod iron, aluminum steel explosion welding plate is welded together, leads to
Fixture takes to get off, and except composition backing, remaining all adopts stainless steel to whole welding backing frame.Welding backing frame 4 includes U
Shape connector 14, support bar 15, sawtooth liner 16, wherein composition backing 17 are directly placed above sawtooth liner 16, as weldering
The bottom of seam, described sawtooth liner is zigzag with the contact surface of described composition backing.Described support bar is used for supporting welding
Backing plate 17；Described U-shaped connector is used for connecting two composition backings 17.Whole welding backing frame 4 is placed on the lining of fixture pedestal
On base.
During aluminium electroloysis overhaul, new cathode steel bar is arranged on it is ensured that the two is substantially parallel on aluminium cell station, position
Error is less than 1mm.
(1) by fixture pedestal frame directly over cathode steel bar, it is fixed by bolt.(2) fixture chock and aluminum
Steel explosion welding plate is positioned by bolt, and inserts in the hook-shaped seat of fixture pedestal.(3) anti-deformation plate is buckled in fixture pedestal
The anti-deformation panel seat of hook-shaped seat obliquely downward on.(4) welding backing frame is arranged on the gasket base of fixture pedestal.
During installation, confirm that fixture and welding gun do not interfere, and apply one layer of kerosene in chucking surface, prevent from welding
Stick together in journey.
After the completion of welding, treat that workpiece cools down, dismantled according to the order contrary with installation process.(1) first will
Welding backing frame takes out.(2) anti-deformation plate is taken off from anti-deformation panel seat.(3) 4 bolts of fixture chock are unclamped, will
Fixture chock takes off, and when welding completes, aluminum steel explosion welding plate is welded as a whole with cathode steel bar.(4) unclamp fixture pedestal
8 bolts, by fixture pedestal from top take out.
In sum, the weld jig invented can be realized being rapidly assembled and disassembled, and effectively prevents welding deformation.
Particular embodiments described above, has carried out detailed further to the purpose of the present invention, technical scheme and beneficial effect
Describing in detail bright it should be understood that the foregoing is only the specific embodiment of the present invention, being not limited to the present invention, all
