Abstract
The utility model relates to a wing box for the front frame of the loader , which is provided with a beam structure of the elliptical tube. The utility model comprises an outer wing plate and an inner wing plate. The utility model is characterized in that the outer wing plate is connected with the inner wing plate by means of the beam of the elliptical tube. The utility model has the advantages that the utility model can solve the problem that the welding seam of the beam structure cracks , and the utility model simplifies the technology making processes and lowers the manufacturing cost.
Description
Technical field
The utility model relates to a kind of loader front vehicle frame wing case that has the oval tube beam structure, belongs to the loader technical field.
Background technology
At present, the uniform cross section structure that the frame wing case crossbeam of general-duty loader front truck welds with the sheet material compacting on the market, uniform cross section crossbeam such as Fig. 1 of welding form, shown in 2: outer wing plate 1 is connected with interior wing plate 2 by crossbeam 3, and crossbeam 3 as shown in Figure 3, be to form by welding through pressure-formed two header boards 6, profile is the uniform cross section structure, it and interior wing plate 2, outer wing plate 1 is formed front vehicle frame wing case, because crossbeam 3 structures have asymmetry, make itself and interior wing plate 2, there are two stress concentration positions in the weld seam of outer wing plate 1: weld seam position 4 easy to crack and weld seam position 5 easy to crack, causing herein, weld seam often ftractures.
Summary of the invention
The purpose of this utility model provides a kind of raising single-piece structural strength, improves the loader front vehicle frame wing case that weld cracking has the oval tube beam structure.
For realizing above purpose, the technical solution of the utility model provides a kind of loader front vehicle frame wing case that has the oval tube beam structure, comprises outer wing plate and interior wing plate, it is characterized in that outer wing plate is connected by the oval tube crossbeam with interior wing plate.
The utility model adopts solid drawn pipe, utilize compacting tool set directly to be pressed into oval or similar ellipse, both guaranteed the single-piece structural strength, simplified manufacture craft again, also reduced cost of manufacture, when particularly this crossbeam docks welding with other sheet material, can realize the arc transition of weld seam, avoid causing structure crack because of the transition of weld seam right angle occurring.
The utility model has the advantages that the phenomenon that can solve the beam structure weld cracking, simplify technology manufacturing process, reduce production costs.
Description of drawings
Fig. 1,2 is crossbeam position view in front vehicle frame wing case;
Fig. 3 is the beam structure scheme drawing;
Fig. 4 is a kind of loader front vehicle frame wing box structure scheme drawing that has the oval tube beam structure.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 4, be a kind of loader front vehicle frame wing box structure scheme drawing that has the oval tube beam structure, described a kind of loader front vehicle frame wing case that has the oval tube beam structure is made up of outer wing plate 1, interior wing plate 2 and oval tube crossbeam 7, and outer wing plate 1 is connected by oval tube crossbeam 7 with interior wing plate 2.
Crossbeam 7 is an ellipsoidal structure, can utilize compacting tool set to suppress by solid drawn pipe, this forming method technology is simply effective, and the contour structures design can guarantee the requirement of strength of whole parts again, can reduce cost of manufacture to a great extent, in addition, crossbeam 7 because crossbeam 7 outlines are arc transition substantially, has guaranteed that weld seam seamlessly transits with outer wing plate 1, when interior wing plate 2 welds, avoided weld stress to concentrate, and convenient welding.
