The specific embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
As Figure 1-Figure 4, the present embodiment metal box prestretched welding deflection machine, comprising: frame 1, rotating frame 3 and motor 2; The both ends of frame 1 are provided with rotating shaft 11, and motor 2 is in transmission connection with rotating shaft 11; Rotating frame 3 comprises and encloses frame 31, bracket 32, compactor 33, top-fastener 34 and strainer 35, the end of enclosing frame 31 is connected in rotating shaft 11, the both sides of enclosing frame 31 are respectively arranged with a plurality of brackets 32, and bracket 32 is perpendicular to enclosing frame 31, and an end of bracket 32 is provided with supporting plate 321; The other end of bracket 32 is provided with compactor 33, compactor 33 comprises and is fixed frame 331 and clamping screw 332, be fixed on frame 331 and offer the first screwed hole (not shown), clamping screw 332 is threaded in the first screwed hole, is fixed frame 331 and is fixed on bracket 32; Be positioned at and enclose frame 31 and wherein on the bracket 32 of a side, be provided with top-fastener 34, top-fastener 34 comprises and holds out against fixed mount 341 and fastening screw 342, hold out against and on fixed mount 341, offer the second screwed hole (not shown), fastening screw 342 is threaded in the second screwed hole, holds out against fixed mount 341 and is fixed on bracket 32; The both ends of enclosing frame 31 are provided with relative strainer 35, strainer 35 comprises the frame 351 that is strained and fixed, stretching screw 352 and nut 353, be strained and fixed on frame 351 and offer through hole (not shown), stretching screw 352 is inserted in through hole, and nut 353 is threaded on stretching screw 352.
Particularly, the present embodiment metal box prestretched welding deflection machine can be assembled in metal box to be welded in rotating frame 3 in advance, after the assembled moulding of metal box to be welded, be placed on to enclose in frame 31 and by supporting plate 321 and support, and by adjusting clamping screw 332 and fastening screw 342, metal box to be welded is positioned fixing, under the effect of compactor 33 and top-fastener 34, the gap that can guarantee weld seam to be welded in the metal box after assembled can keep uniformity, to improve formed weldquality after welding.And in order to alleviate welding deformation, strainer 35 in the present embodiment applies pulling force by the both ends at metal box to metal box, metallic plate in metal box is carried out to prestretched, thereby in the welding process of long weld seam, weld seam is all the time in being subject to state of tension, after welding completes, the pre-tension deformation with is before offset in the distortion that the cooling contraction of weld seam produces, thereby effectively alleviates the deformation extent of metal box.
Further, for convenient, assembled good metal box is placed in rotating frame 3, be fixed frame 331 and comprise holder 3311 and cursor 3312, cursor 3312 is rotating to be connected on holder 3311, on cursor 3312, offer the first screwed hole, on holder 331 and cursor 3312, be respectively arranged with pin hole (not shown), in pin hole, be inserted with latch 3313.Concrete, in the time need to assembled good metal box being put in rotating frame 3, latch 3313 to be extracted out from pin hole, rotation cursor 3312 opens metal box to be placed in rotating frame 3 easily; Then, rotation cursor 3312 resets, and latch 3313 is inserted in pin hole, just can metal box be squeezed on supporting plate 321 by compactor 33.And for the more effective sidewall to metal box positions fixingly, the both ends up and down of bracket 32 are provided with respectively top-fastener 34.Preferably, on supporting plate 321, be provided with the first cushion pad 322, on the opposite face of bracket 32, be provided with the second cushion pad 323, by the first cushion pad 322 and 323 pairs of extruded metal boxes of the second cushion pad, support, can avoid metal box because of stressed excessive deforming.
The present invention also provides a kind of metal box prestretched welding method, adopts above-mentioned metal box prestretched welding deflection machine, and concrete steps comprise:
Step 1, metal box to be welded is placed in rotating frame, the bottom surface of metal box is supported by supporting plate, and the compacted device of end face of metal box pushes, and a side of metal box is resisted against on bracket, and the another side of metal box is pushed by top-fastener;
Stretching screw in step 2, strainer is welded on metal box, and by rotating nut, metal box is carried out to prestretched processing;
Step 3, metal box is carried out to soldering.
