Abstract
The invention discloses a welding process for a stiffening beam on the middle section of a longitudinal beam of a framework vehicle. The welding process mainly includes the steps that 1), the bevel angle of the stiffening beam on the middle section of the longitudinal beam is reduced, and the root face length is increased; and 2), a left weld bead and a right weld beam of the stiffening beam on the middle section of the longitudinal beam are divided into multiple sections which are intermittently welded in an intersecting manner. The problem that a stiffening beam on the middle section of a longitudinal beam is likely to incline is solved, on the premise that the quality of a welding joint is guaranteed, the welding deformation of the stiffening beam on the middle section of the longitudinal beam is effectively reduced by means of improving the welding process and adjusting the welding sequence, the parallelism of the stiffening beam on the middle section of the longitudinal beam and a lower flange of the longitudinal beam is controlled within 1.5 mm, the percent of pass of products is increased, and the whole vehicle performance of the framework vehicle is guaranteed.
Description
Technical field
The invention belongs to Welded field, be specifically related to a kind of frame vehicle longeron stage casing buttress brace welding procedure.
Background technology
Frame vehicle mainly coordinates with container and is used for long-distance transportation, and mainly through being welded to connect between each several part, wherein, longeron stage casing buttress brace is two webs, is about 4 ~ 5.5m, is the welderings of double-deck twice during welding.
In prior art, longeron stage casing buttress brace point adopts monosymmetric welding method from the beginning to the end admittedly afterwards, more arrives its accumulative deflection of afterbody larger, and after causing welding to complete, the wing plate of longeron stage casing buttress brace tilts serious, not parallel with longeron lower wing plate.Due to these parts welded after cannot to carry out effective adjusting orthopedic, not only have impact on the welding of miscellaneous part, also reduce the mechanical property of car load.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of welding procedure that effectively can control longeron stage casing buttress brace welding deformation, improve frame vehicle vehicle performance.
For achieving the above object, the invention provides following technical scheme: a kind of frame vehicle longeron stage casing buttress brace welding procedure, mainly comprises the following steps:
1) reduce longeron stage casing buttress brace bevel angle, increase root face length;
2) two welding beads about the buttress brace of longeron stage casing are divided into some sections and the interrupted welding of intersection.
Further, described step 1) in, longeron stage casing buttress brace bevel angle is 45 °, the long 2mm of root face.
Further, described step 2) in, about the buttress brace of longeron stage casing, two every bar welding beads of welding bead are divided into 7 sections, every section of long 570 ~ 790mm of welding bead.
Further, described step 2) in the interrupted welding sequence of intersection be: section 1 → backhand welding road, section 3 → backhand welding road, section 9 → backhand welding road, section 4 → left welding bead section 5 → left welding bead section 3 → backhand welding road, section 6 → backhand welding road, left welding bead section 4 → backhand welding road section 2 → left welding bead section 7 → left welding bead section 1 → backhand welding road section 7 → left welding bead section 2 → left welding bead section 6.
Beneficial effect of the present invention is: solve longeron stage casing buttress brace and easily produce the problem of inclination in welding process, under the prerequisite ensureing weldquality, by improving welding procedure, adjustment welding sequence, effectively reduce the welding deformation amount of longeron stage casing buttress brace, the depth of parallelism of longeron stage casing buttress brace and longeron lower wing plate is controlled within 1.5mm, improves the qualification rate of product, ensure that the vehicle performance of frame vehicle.
Accompanying drawing explanation
In order to make object of the present invention, technical scheme and beneficial effect clearly, the invention provides following accompanying drawing and being described:
Fig. 1 is structural representation of the present invention;
Fig. 2 is longeron stage casing buttress brace structural representation;
Fig. 3 is longeron stage casing buttress brace welding sequence schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in the figure, the frame vehicle longeron 1 stage casing buttress brace welding procedure in the present invention, mainly comprises the following steps: 1) reduce longeron stage casing buttress brace 2 bevel angle α, increases root face length b; 2) buttress brace about 2 two welding beads in longeron stage casing are divided into some sections and intersect and intermittently weld.
Concrete, single double V-groove angle [alpha] in the present invention is reduced into 45 ° by 60 ° of the prior art, root face b extends to 2mm by 1mm, bevel angle after improvement diminishes, root face becomes large, under the prerequisite ensureing root of weld fusion effect, reduce the loading of weld metal, improve speed of welding, effectively prevent the welding deformation caused because weld metal shrinks in welding process.
In the present invention, about the buttress brace of longeron stage casing, two every bar welding beads of welding bead are divided into 7 sections, every section of long 570 ~ 790mm of welding bead, and preferably each section of welding bead length is 700mm; Interrupted welding sequence of intersecting is: section 1 → backhand welding road, section 3 → backhand welding road, section 9 → backhand welding road, section 4 → left welding bead section 5 → left welding bead section 3 → backhand welding road, section 6 → backhand welding road, left welding bead section 4 → backhand welding road section 2 → left welding bead section 7 → left welding bead section 1 → backhand welding road section 7 → left welding bead section 2 → left welding bead section 6.By welding sequence of rationally arranging, welding heat rapid dispersion can not only be made, not affect the welding of lower road weld seam simultaneously, effectively prevent the generation of welding deformation.
What finally illustrate is, above preferred embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although by above preferred embodiment to invention has been detailed description, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from claims of the present invention limited range.
