As shown in Figures 1 to 5, the shaping of cross tubular member 10 and cross tubular member 20 is relatively difficult, commonly uses
Manufacturing process have：
First, part is split into upper piece and bottom sheet, be formed separately, then by upper piece 11 and 12 split of bottom sheet, at butted line
Two panels is integrally welded (as shown in Figure 3)；
2nd, part is split into three pipes by another kind, and two short tubes 21 are welded on one by unexpected misfortune with long tube 22 respectively
Rise (as shown in Figure 4)；
3rd, a four-way pipe 23 is shaped out, then four pipes 24 are welded together with four-way pipe 23 (such as Fig. 5 institutes respectively
Show).
However, the forming process of these above-mentioned common manufacturing process is all more complicated, and location difficulty, the size essence of part
Spend it is poor, manufacture cost it is higher.
The content of the invention
The technical problem to be solved in the present invention is in order to overcome in the prior art cross tubular member forming process it is complicated,
A kind of and the defects of location difficulty, there is provided forming method of cross tubular member.
The present invention is to solve above-mentioned technical problem by following technical proposals：
A kind of forming method of cross tubular member, its feature are that the forming method includes：
The first slab is made, the shape of first slab is designed to the form fit with cross tubular member, and
It is processed；
The second slab is made, stamps out the centre position shape of the top half of the cross tubular member；
First slab and second slab are combined, by the first slab after shaping and the second slab split,
And it is welded as a whole.
It is preferred that in the step of the first slab of the making, the first slab punching press is obtained into the cross part
Integrally-built lower plate portions shape, and carry vertical face.
It is preferred that in the step of the first slab of the making, the punching press again to first slab is further included, by institute
Shape of the vertical roll synthesis type needed for final part is stated, and the butted line intervolved is welded.
It is preferred that the first slab is sketch blank.
It is preferred that splicing multiple second slabs on first slab, second slab is welded on first slab
On corresponding part.
The positive effect of the present invention is：
The forming method of cross tubular member of the present invention carries out monolithic molding to the main body of part, can be to avoid because of welding
Dimensional accuracy is bad caused by the positioning and deformation of process, while also avoid the forming process of complexity, so as to reduce life
Produce cost.Good size essence can be obtained while manufacture cost is effectively reduced using forming technique of the present invention
Degree.

Embodiment
For the above objects, features and advantages of the present invention can be become apparent, the tool below in conjunction with attached drawing to the present invention
Body embodiment elaborates.
Many details are elaborated in the following description to facilitate a thorough understanding of the present invention, still the present invention can be with
Implemented using other different from other manner described here, therefore the present invention is from the limit of following public specific embodiment
System.
Fig. 6 be cross tubular member of the present invention forming method in abnormal shape slab schematic diagram.Fig. 7 is cross of the present invention
Schematic diagram in the forming method of shape tubular member after special-shaped slab punching press.Fig. 8 is the shaping of cross tubular member of the present invention

Schematic diagram.Figure 10 is the first slab in the forming method of cross tubular member of the present invention and the schematic diagram of the second slab splicing.
A kind of shaping side of cross tubular member is disclosed as shown in Fig. 6 to Figure 10, in one embodiment of the present of invention
Method, the forming method include：
The first slab 30 is made, the shape of the first slab 30 is designed to the form fit with cross tubular member, and
It is processed.Specifically, the first slab 30 uses sketch blank, and 30 punching press of the first slab is obtained the cross part
Integrally-built lower plate portions shape, and carry vertical face 31.
Then, punching press again is carried out to the first slab 30, vertical face 31 is intervolved to the shape being shaped to needed for final part
Shape, and the butted line intervolved is welded, form sealing wire 32.
The second slab 40 is made, stamps out the centre position shape of the top half of the cross tubular member.
Finally, the first slab 30 and the second slab 40 are combined, by 40 split of the first slab 30 and the second slab after shaping,
And be welded as a whole, sealing wire 41 is formed, obtains final cross tubular member.
The pipe fitting schematic diagram that Figure 11 forms for multiple cross in the forming method of cross tubular member of the present invention.Figure 12
