Summary of the invention
For above weak point of the prior art, the present invention aims to provide a kind of rational in infrastructure, easily manufactured welded type axle beam, and its manufacturing process is simple, with low cost.
Technical scheme of the present invention: a kind of welded type axle beam, it comprises the hollow quadratic body structure be welded by upper cover plate, lower cover and two webs, described two webs are located between described upper cover plate and lower cover, and described upper cover plate and lower cover both sides are provided with the welding reserved place welding described web.
The two ends of described hollow quadratic body structure are welded with the key seat in expense hole.
Described key seat is solid drawn pipe.
Described key seat is welded on described lower cover, and through hole is established in this lower cover position corresponding to described pin-and-hole;
Described two webs are welded on the sidewall of key seat;
Be provided with at described upper cover plate two ends the recess matched with key seat, described upper cover plate is directly welded on the top of described key seat.
Outside key seat on described hollow quadratic body structure, lower end is provided with the bevel for welding welded with described lower cover.
Described upper cover plate is welded with the flat spring bracket offering bolt hole.
Present invention also offers a kind of welding process of welded type axle beam, stamping forming upper cover plate, lower cover and two web Combination Welding are formed, by carrying out lower weldering at welding reserved place between described upper cover plate, lower cover and two webs;
Described key seat is built up on the position at described lower cover two ends, and described lower cover and key seat carry out lower weldering by the bevel for welding of key seat lower end;
Form weld bond between described two webs and described key seat, carry out lower weldering at this weld bond;
By welding up and down at described upper cover plate between described upper cover plate and key seat.
Polishing welding seams after welding.
On the basis ensureing product strength and in-use performance, the main welding processing that adopts is made, and product weight decreases 5% than this axle beam of forging, and energy resource consumption reduces greatly, and technological process simplifies, and the technique three wastes obviously reduce.
The present invention has rational in infrastructure, dependable performance, and manufacturing process is simple, the advantages such as energy consumption is low, and environmental pollution is little, is suitable for applying.

Detailed description of the invention
The present invention is further described below in conjunction with specific embodiment and accompanying drawing.
Refer to Fig. 1 to Fig. 5, described welded type axle beam, it comprises the hollow quadratic body structure be welded by upper cover plate 1, lower cover 2 and two webs 3, described two webs 3 are located between described upper cover plate 1 and lower cover 2, and described upper cover plate 1 and lower cover 2 both sides are provided with the welding reserved place 31 welding described web 3.
The upper cover plate that the present invention uses, lower cover 2 and web 3 all adopt high strength low alloy steel plate, ensure intensity and the in-use performance of product, be welded into hollow quadratic body structure, higher than " I-shape " axle beam that casting or forging are processed in structural strength, and casting or forging axle beam easily crack fracture at arm, service life is short.And adopt in the present invention four pieces of plate irons to weld vertically, effectively prevent product breakage problem, through being that the preproduction workpiece way of escape tries 30000 kilometers of detections, this welded type axle beam is without defects such as distortion, crackings.
Described two webs 3 are welded between upper cover plate 1 and lower cover 2, and on upper and lower cover plate 1,2, be installed with the welding reserved place 31 welding described web 3, as shown in Figure 2, like this, when welding, do not need additionally to offer bevel for welding at two web 3 upper and lower sides, and directly on welding reserved place 31, carry out lower weldering, decrease welding process step, save weld time, power consumption reduces.
Further, the key seat 4 in expense hole is welded with at the two ends of described hollow quadratic body structure, this example preferably key seat 4 is solid drawn pipe, see Fig. 3, Fig. 4 and Fig. 5, be welded in by key seat 4 on described lower cover 2, namely key seat 4 is on lower cover 2, weld, and described upper cover plate 1 and two webs 2 are welded with this key seat 4, finally or before welding, described lower cover 2 position that the pin-and-hole on described key seat 4 is corresponding is drilled with through hole.Due to the style characteristic of axle beam, and described web 3 is plate iron, itself has certain thickness, like this, when welding, only the bevel for welding 41 welded with described lower cover 2 need be provided with in lower end outside the key seat 4 on described hollow quadratic body structure, specifically as shown in Figure 4.The junction of web 3 and key seat 4, itself has sealing 32 between the sidewall of namely web 3 and described key seat 4, can carry out lower weldering, so do not need additionally to carry out beating bevel for welding, as shown in Figure 5.Be provided with at described upper cover plate 1 two ends the recess matched with key seat 4, described upper cover plate 1 is directly welded on the top of described key seat 4, and position while welding is on this upper cover plate 1.
Finally, described upper cover plate 1 is welded with the flat spring bracket 5 offering bolt hole.
The welding process of welded type axle beam of the present invention, specifically see Fig. 2 to 5, stamping forming upper cover plate 1, lower cover 2 and two web 3 Combination Welding are formed, particularly, by carrying out lower weldering at welding reserved place 31 between described upper cover plate 1, lower cover 2 and two webs 3; Described key seat 4 is built up on the position at described lower cover 1 two ends, and described lower cover 2 carries out lower weldering with key seat 4 by the bevel for welding 41 of key seat 4 lower end; The sealing 32 formed between described two webs 3 and described key seat 4, and carry out lower weldering at this sealing 32; By welding at described upper cover plate about 1 between described upper cover plate 1 and key seat 4, finally weld seam after welding carries out grinding process, can axle beam be drawn, after subsequent treatment of carrying out spraying paint etc., can finished product be obtained.
The foregoing is only the detailed description of present pre-ferred embodiments and graphic, be not used for limiting the present invention, the embodiment of all similar changes done according to creation spirit of the present invention or approximate construction, all should be contained among the present invention.
