Description
Technical field
The invention belongs to welding field, and in particular to a kind of welding piece anti-deformation device.
Background technology
Before bearing device and structural steelwork construction, generally require to weld a large amount of technique test specimens to formulate welding procedure.Examination
Part causes temperature distributing disproportionation on weldment even in welding process because localized hyperthermia heats, so that Specimen Shape and size
Precision changes, it is difficult to reach technical requirements.Prestrain method and multiple inversion method being used typically in welding more, but these are only
The method of test piece deformation is prevented by experience can not meet requirement.This is accomplished by increasing weldment using the method for rigidly fixing
Rigidity or constraint (restraint) degree, so as to reach the purpose of Reducing distortion.
At present, making complexity, high cost that the rigid fixation means commonly used in construction production have, though the simple structure having,
But anti-deformation effect is bad, mostly disposable application apparatus.
The content of the invention
It is an object of the invention to provide a kind of welding piece anti-deformation device, the device anti-deformation effect is good, operation letter
Single, repeatable to utilize, welding effect is good, low cost.
The technical solution adopted in the present invention is：
A kind of welding piece anti-deformation device, including base plate, two backing plates and two pressing plates, two backing plates are placed on bottom
On the top surface of plate, two pressing plates are individually positioned on two top surfaces of backing plate, and gap A, two pressing plates are formed between two backing plates
Between formed gap B, gap A and gap B be parallel to each other and be respectively positioned on the middle position of base plate, base plate, backing plate and pressing plate pass through
The bolt and nut component positioned at four angles of base plate position is connected respectively；During welding, two welding pieces are fixed respectively
At two groups between backing plate and pressing plate, welding groove is located at gap A and gap B in the range of the coincidence that base plate is projected.
Further, two pressing plate sides facing each other are equipped with groove diagonally downward.
Further, base plate, backing plate are identical with pressing plate length.
The beneficial effects of the invention are as follows：
1. when welding, the fastening face that the fastening force and backing plate and pressing plate formed using bolt and nut component are formed is to welding
Test specimen is rigidly fixed, and only welding groove stretches out, and can effectively reduce the angle change that welding piece is produced because local heating is uneven
Shape, flexural deformation, can especially effectively reduce wave transformation of the thin plate caused by inequality of being heated, and anti-deformation effect is good；By tightening
It is simple to operate, repeatable to utilize with release bolt and nut component, you can welding piece is fixed and is taken out, efficiency high；Backing plate makes
Welding piece leaves certain space (gap A) in bottom in welding, facilitates weld reinforcement part to shape or add liner part, welds
Connect effect good；The device is made up of several blocks of plates and bolt and nut component, makes simple, low cost.
2. the swing of welding gun leaves enough operating spaces when groove is welding.
3. base plate, backing plate are identical with pressing plate length, and base plate, backing plate and pressing plate can be in length direction and widths simultaneously
Row, has two identical true edges when so setting bolt hole, and locating and machining is simple, easy to make.
Brief description of the drawings
Fig. 1 is the front view of the embodiment of the present invention.
The top view of Fig. 2 Fig. 1
In figure：1- base plates；2- backing plates；3- welding pieces；4- pressing plates；5- bolts；6- packing rings；7- nuts.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, a kind of 1, two backing plates 2 of the anti-deformation device of welding piece 3, including base plate and two pressures
Plate 4, two backing plates 2 are placed on the top surface of base plate 1, and two pressing plates 4 are individually positioned on two top surfaces of backing plate 2, two pads
Formation gap B, gap A and gap B between gap A, two pressing plates 4 is formed between plate 2 to be parallel to each other and be respectively positioned in base plate 1
Centre position, base plate 1, backing plate 2 and pressing plate 4 are by respectively positioned at bolt and nut component (including the spiral shell of 1 four angles of base plate position
Bolt 5, packing ring 6 and nut 7) connection；During welding, two welding pieces 3 are pressed abd fixed between two groups of backing plates 2 and pressing plate 4 respectively,
Welding groove is located at gap A and gap B in the range of the coincidence that base plate 1 is projected.
During welding, the fastening face that the fastening force and backing plate 2 and pressing plate 4 formed using bolt and nut component are formed is to welding
Test specimen 3 is rigidly fixed, and only welding groove stretches out, and can effectively reduce welding piece 3 because of the uneven angle for producing of local heating
Deformation, flexural deformation, can especially effectively reduce wave transformation of the thin plate caused by inequality of being heated, and anti-deformation effect is good；By twisting
Tight and release bolt and nut component, you can welding piece 3 is fixed and taken out, simple to operate, repeatable to utilize, efficiency high；Pad
Plate 2 makes welding piece 3 leave certain space (gap A) in bottom in welding, facilitates weld reinforcement part to shape or add pad
Part, welding effect is good；The device is made up of several blocks of plates and bolt and nut component, makes simple, low cost.
As shown in figure 1, in the present embodiment, two sides facing each other of pressing plate 4 are equipped with groove diagonally downward.Slope
The swing of welding gun leaves enough operating spaces when mouth is for welding.
As shown in Fig. 2 in the present embodiment, base plate 1, backing plate 2 are identical with the length of pressing plate 4.Base plate 1, backing plate 2 and pressing plate 4
Length is identical, and base plate 1, backing plate 2 and pressing plate 4 can have in length direction and width side by side when so setting bolt hole
Two identical true edges, locating and machining is simple, easy to make.
In the present invention, the groove type of welding piece is not limited to the V-butt shown in Fig. 1, X-shaped, the Y for thus extending
The groove types such as shape are effectively applicable, when two-sided welding is needed, can be after side welding be completed and is cooled sufficiently, and upset weldering
Connect opposite side.In the present invention, it is not only limited to the downhand position shown in Fig. 1, it is adaptable to horizontal, vertical, overhead position, specifically does
Method is that this device base plate 1 is fixed on corresponding upset moulding bed.
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
