Abstract
The invention discloses a kind of process for processing large excavator car door, it is characterized in that, first air inlet grid is integrally welded, will left stud, middle stud, upper horizontal bar, diagonal bar one, diagonal bar two, right stud, lower horizontal bar, small stud weld together composition air inlet grid；Then left reinforcement, right reinforcement, door hinge, reinforcement and door-plate are welded；Then left stud, right stud are welded with left reinforcement, right reinforcement respectively, makes two component group welderings；It is finally using high strength structural adhesion that middle stud, upper horizontal bar, lower horizontal bar, small stud is Nian Jie with door-plate.The present invention increases the process of strength structure glue sticking using welding, and strengthening, door-plate is rigid simultaneously, effectively reduces automobile door welding deformation, later stage is without polishing, scraping can just paint after ash, electrophoresis, greatly improve the presentation quality of car door and the efficiency of batch production.
Description
Technical field
The present invention relates to a kind of process for processing large excavator car door, and in particular to one kind processing large excavator
Process with air inlet grid car door.
Background technology
In excavator manufacture field, car door is the outward appearance important component of pick machine, the overall direct shadow of workmanship of car door
Ring and arrive complete machine presentation quality.Car door is to be aided with welding reinforcement by the door-plate suppressed to form, large excavator heat sink side car door
Upper major part is all welded with air inlet grid, as Figure 1-3, including the door-plate 4 with air inlet grid 14, with air inlet grid 14
Left, center, right are respectively equipped with left stud 2, middle stud 3, right stud 10, and the left side of left stud 2 is provided with left reinforcement 1, right stud 10
Right side be provided with right reinforcement 5, edge of the air inlet grid 14 at door handle 15 be provided with small stud 13, upside be provided with upper horizontal bar
6, downside is provided with lower horizontal bar 12；The downside of door-plate 4 is provided with reinforcement 11, and the side of door-plate 4 is provided with door hinge 9；Air inlet grid 14
Both sides be additionally provided with two diagonal bars, i.e. diagonal bar 1 and diagonal bar 28.
Traditional preparation method is directly to weld together air inlet grid 14 with door-plate 4, because the sheet material of door-plate 4 compares
Thin, air inlet grid 14 easily causes door-plate 4 when welding and deformed, and outer surface has crator to need manual polishing, and later stage surface treatment is needed
Scrape ash to strike off, artificial intensity is big.To reduce welding deformation, production efficiency is improved, without manual polishing, scrapes grey i.e. sprayable,
Ensure under the performance requirement that air inlet grid 14 is firmly connected with door-plate 4, it is necessary to assure air inlet grid 14 is not welded directly with door-plate 4
Connect.
The content of the invention
When problem to be solved by this invention is to provide a kind of car door process and can solve air inlet grid and door-plate and weld
The deformation caused and outside crator, improve batch production efficiency, reduce artificial surface processing man-hour.
In order to solve the above problems, the technical scheme is that there is provided a kind of technique for processing large excavator car door
Method, it is characterised in that first integrally weld air inlet grid, will left stud, middle stud, upper horizontal bar, diagonal bar one, diagonal bar two,
Right stud, lower horizontal bar, small stud weld together composition air inlet grid；Then by left reinforcement, right reinforcement, door hinge, plus
Strengthening tendons is welded with door-plate；Then left stud, right stud are welded with left reinforcement, right reinforcement respectively, makes two components
Group weldering；It is finally using high strength structural adhesion that middle stud, upper horizontal bar, lower horizontal bar, small stud is Nian Jie with door-plate.
Preferably, between the left stud and left reinforcement, the welding manner between right stud and right reinforcement is used
Intermittent weld mode is welded.
Preferably, described high strength structural adhesion is ergo 1920.
The present invention increases the process of strength structure glue sticking using welding, and strengthening, door-plate is rigid simultaneously, effectively
Automobile door welding deformation is reduced, the later stage, scraping can just paint after ash, electrophoresis without polishing, greatly improve the outward appearance matter of car door
Amount and the efficiency of batch production.
Brief description of the drawings
Fig. 1 is the front view with air inlet grid car door；
Fig. 2 is Fig. 1 top view；
Fig. 3 is Fig. 1 left view.
Embodiment
To become apparent the present invention, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment
A kind of process for processing large excavator car door：
Step 1）：By left stud 2, middle stud 3, upper horizontal bar 6, diagonal bar 1, diagonal bar 28, right stud 10, lower horizontal bar 12, small
Stud 13 welds together composition air inlet grid 14；
Step 2）：Left reinforcement 1, right reinforcement 5, door hinge 9, reinforcement 11 and door-plate 4 are welded；
Step 3）：Left stud 2, right stud 10 are carried out with left reinforcement 1, right reinforcement 5 using intermittent weld mode respectively
Welding, makes step 1）Obtained component and step 2）Obtained component group weldering；
Step 4）：High strength structural adhesion ergo 1920 is finally used by middle stud 3, upper horizontal bar 6, lower horizontal bar 12, small stud
13 is Nian Jie with door-plate 4, during processing, must ensure do not have solder joint on the big face of middle thin plate of door-plate 4.
