Step S4: upper flange and lower wing plate are welded with web respectively, thus the obtained bench box bottom side beams with the second default camber;
In the present embodiment, adopt in the same way, upper flange 211 and lower wing plate 212 weld with web 213 by synchronous and that be symmetrically welded mode respectively.In the same way, when synchronous and symmetry refers to lower wing plate and web 213 on welding, the welding bead of web 213 both sides needs synchronous, in the same way, is symmetrically welded, adopt this welding manner can avoid the uneven of welding stress and the postwelding strain that causes, thus reduce and reduce crossbeam side sway.Due to the bottom side beams web 213 of bellows-shaped after welding with upper flange 211 and lower wing plate 212 owing to suffering restraints, the originally elasticity loss that produces of bellows-shaped, bottom side beams 21 becomes a buttress bracing struts body, so bottom side beams 21 can not produce elastic deformation because of extraneous applying power easily after welding.And due to the relation of welding stress, second of bottom side beams 21 after shaping presets camber c can be less than the first default camber b, when first default camber b is 50mm ~ 80mm, it is 40mm ~ 65mm that after welding fabrication second presets camber c, when first default camber b is 15mm ~ 45mm, it is 10mm ~ 30mm that after welding fabrication second presets camber c, and camber can diminish accordingly, so need when selecting default camber to consider variable quantity.
Present invention also offers a kind of method for making of bench box, the method for making of bench box comprises the method for making of above-mentioned bench box bottom side beams.
The manufacturing process of bench box directly adopts the direct bottom side beams of above-mentioned method for making.
Present invention also offers a kind of bench box bottom side beams 21, consult Fig. 7 to Figure 14, bench box bottom side beams 21 comprises: upper flange 211, lower wing plate 212 and the web 213 being connected upper flange 211 and lower wing plate 212, bottom side beams 21 is in I shape, the longitudinal direction of web 213 is bellows-shaped, bottom side beams 21 is bent to form second by lower wing plate 211 to upper flange 212 and presets camber, and the second default camber is 40mm ~ 65mm or 10mm ~ 30mm.
Principle of the present invention is described in detail below for the present embodiment.
First, the web 213 of bellows-shaped is out of shape generation camber by applying pressure, so the width a of web 213 is identical with raw MAT'L, avoid cutting operation, do not produce leftover pieces.
Secondly, bottom side beams germule supports side by cylinder 4, block 3 stops opposite side, thus bottom side beams germule is fixed, and support due to cylinder 4 and make bottom side beams germule bending laminating block 3, the camber b of such bottom side beams germule is just identical with the camber b of block 3, so just can adjust the camber of bottom side beams germule easily by the position of adjustment block 3, thus obtains the bottom side beams germule that first presets camber b.
Finally, just complete the making of bottom side beams 21 by welding, now bottom side beams 21 presets camber c because the relation of welding stress reaches second.
In sum, the present invention is by being made into ripple struction by web thus adding the elasticity of web, camber is bent to form after making the just indusium both sides clamping of whole bottom side beams, therefore namely the width of web is raw-material width, so do not need the processing mode cut, thus improve production efficiency and product design, and leftover pieces can not be produced and reduce cost, the web of bellows-shaped adds the stability of bottom side beams simultaneously, thus makes web can adopt thinner material to reduce costs.
