Specific embodiment
Hereafter to the detailed description of exemplary embodiment of the present invention with reference to attached drawing, which forms one of description
Point, it has been shown as example enforceable exemplary embodiment of the invention in the figure.Although these exemplary embodiment quilts
Sufficiently describe in detail so that those skilled in the art can implement the present invention, it is to be understood that can realize other embodiments and
Can without departing from the spirit and scope of the present invention to the present invention various changes can be made.Hereafter to the embodiment of the present invention
More detailed description is not limited to required the scope of the present invention, and just to be illustrated and do not limit pair
The description of the features of the present invention and feature to propose to execute best mode of the invention, and is sufficient to make those skilled in the art
It can implement the present invention.Therefore, the scope of the invention is only defined by the appended claims.
Hereafter detailed description of the present invention and example embodiment are more fully understood in combination with attached drawing, wherein of the invention
Element and feature are identified by appended drawing reference.
Large welded structures part is used widely in metallurgy industry, but metallurgy industry working environment itself is severe, large-scale
Welding structural element needs to bear huge pressure again during the work time, easily causes the deformation of structural member welding position, influences
The service performance of structural member leaves hidden danger for safety in production.Straightening machine base in continuous casting process needs to bear huge pressure
Power, and due to the isostructural influence of crystallizer, withdrawal straightening machine base top surface generally requires to be arranged to the top surface that a part is in cambered surface.It adopts
With whole arc top surface, due to steel stress can deformation occurs, be not without comprovincial stress it is uniform, can to push up
Face deforms unevenness in use, causes the dimensional discrepancy of top surface and default top surface increasing, cannot be bonded with withdrawal straightening machine,
It is easy to cause safety accident.Therefore in the selection course of withdrawal straightening machine top surface, the general folding that similar arc is formed using muti-piece plate
Line.
But in the production process of straightening machine base, weld seam is more, structure is complicated, welding stress and distortion is larger, is welding
Occurs the phenomenon that deforming and changing former package size in termination process, resulting even in machined surface does not have surplus and scrap.For upper
Problem is stated, needs to be designed and improve from structure and processing technology, so that straightening machine base is finally reached requirement, In
In use process, the generation of security risk is reduced, increases the service life of withdrawal straightening machine.
On the welding structural element of straightening machine base, pedestal bilateral symmetry, up and down due to top panel is arc,
There is extremely asymmetry in upper and lower weld seam, be easy to happen the bending deformation scratched, and due to the box-structure of straightening machine base, it is whole
Body is rigidly larger, can not carry out correction process to deformation occurs position.
The main reason for generation of welding deformation is mainly caused by the internal stress that welding thermal process generates, and internal stress generates
Have: welding temperature it is uneven；Molten condition is covered on the contraction of metal at pad；Welding position metal structure transformation and
The rigid constraint of associated workpiece；Welding capacity and welding position not at or it is unreasonable.
Welding deformation is mainly contraction distortion, and the cooling procedure of weld seam is that weld seam by liquid is converted into solid process, is turned
The phenomenon that welding stress and weld seam volume-diminished will be generated during change, so as to cause the reduction of postwelding weldment outer dimension.
(1) welding is shunk, and there are two types of situations for long box bed welding contraction distortion: 1. parallel box bed longitudinal axis side
To contraction, i.e. longitudinal contraction；2. perpendicular to the contraction in box bed longitudinal axis direction, i.e. cross-direction shrinkage.
The Stress calculation of longitudinal contraction can be estimated by following formula:
In above formula: ΔIt is verticalThe longitudinal shrinkage of single layer welding, mm；FHSection of weld joint product, mm2；F- member section accumulates mm2；
L- component length, mm；ξ3Coefficient, ξ3Value is related with welding method and material, is shown in Table 1.
1 ξ of table3The relationship of value and welding method and material
Under the same terms, the mode ξ of using gas protection welding3It is worth smaller, deformation quantity caused by corresponding welding
It is smaller.
In the welding process for carrying out straightening machine base, due to needing to bear the weight of withdrawal straightening machine, the plate thickness of pedestal is chosen
Thicker, so that the weld seam in welding should not use single layer welding, the welding manner of single layer welding is not able to satisfy intensity requirement, uses multilayer
The longitudinal contraction of weldering, FHIt is calculated according to one-pass weld, and by one-pass weld longitudinal shrinkage multiplied by K2。
K2=1+85 εsN, in which: εsThe yield strength of material strains accordingly；The n- number of plies.
Wherein: σsThe yield strength of material；The elasticity modulus of E- material.
The shrinkage of cross-direction shrinkage is smaller compared with the shrinkage of longitudinal contraction, smaller for welding deformation entire effect,
It is negligible.
(2) influence of welding direction and welding sequence
Straightening machine base is that long box structure can generate the bending deformation along bead direction when being welded on panel.
When since plate on one side welded seam, heat affected area is first from here beginning to cool contraction, and the another side of plate is by front weld seam
The effect for assembling power has become tensile region.I.e. the plate welds under tension stress state.The welding deformation when welding of tensile region
It is smaller.
Welding deformation can be divided into the uniform shrinkage along weld seam after being decomposed, so that plate shortens；Another part is formed
Bending deformation, so that plate is bent to welding direction.As shown in figure 4, leftmost side arrow direction is the welding direction of plate, along
It is available along the uniform shrinkage power β of weld seam and bending deformation to carry out stress decomposition to α by welding direction, overall stress such as α
Power γ.
By rationally changing welding direction, bending deformation power γ can be reduced or eliminated, finally makes welding whole more steady
Gu being not susceptible to deformation.Using be symmetrically welded or backstep (i.e. segmented welding, every section of welding direction with welding promote it is total
It is contrary), skip welding, multi-pass welding etc., the residual stress of each welding and the contrary of deformation can be made and mutually offseted
Disappear.
In addition because the difference of size up and down of straightening machine base cross section is larger, weld seam distribution is asymmetric, and board dimensions are uneven
It is even, if not considering welding sequence, the lesser weld seam of shrinkage is first welded, rear to weld the biggish weld seam of shrinkage, the straight-through long weldering of first weldering
Seam, weld the short weld seam being staggered afterwards, can cause the direction of weld seam internal stress is inconsistent, size is uneven, weldment deforms position and
Torsional deformation is presented it is difficult to predict final in direction.
Embodiment 1
As shown in Figure 1-3, a kind of straightening machine base of the present embodiment, including bottom plate 1, side plate 2, panel 3, gusset 4, vertical plate
5 and mounting plate 6.Between mounting plate 6 and bottom plate 1 by the way of being fixedly connected, connection is all made of welding between remaining each plate
Mode.As large-scale structural member, connection type between each component is relatively simple using welding, and more firm
Connection type, so that whole use intensity is higher.
Bottom plate 1 is one block of whole plate, without using the mode of Split type welding, reduces the presence of weld seam, reduction welding is answered
Power, 1 surface of bottom plate are in rectangle, and bottom plate 1 is symmetrically arranged with side plate 2, side along the center line two sides of side square surface length direction
2 quantity of plate is two pieces, and 2 side of side plate is vertical with bottom plate 1 to be connect, and the opposite other side is vertical with panel 3 to be connect.Side plate 2 and bottom
Plate 1 and side plate 2 are all made of the mode of vertical welding, are to make stress at weld seam place huge in order to avoid oblique weld, appearance
Easily in commissure, there is a phenomenon where crack.
Side plate 2 is connected with gusset 4 close to 1 edge of bottom plate on one side, and gusset 4 is welded with bottom plate 1, side plate 2 and panel 3 respectively
It connects, panel 3 includes horizontal segment and segmental arc, and horizontal segment is parallel with bottom plate 1, and horizontal segment and segmental arc are split type, and horizontal segment
It contacts but is not connected to segmental arc.By designing structure, bottom plate 1, side plate 2 and panel 3 provide structure for straightening machine base
Basis, panel 3 are to adapt to the structure of withdrawal straightening machine to be segmented, and contact but unconnected setting, subtract between horizontal segment and segmental arc
Few bending stress as caused by welding, reduces the possibility that deformation occurs of panel 3.
