Description
Technical field
The utility model relates to a kind of spiral welded pipe and produces servicing unit, particularly relates to a kind of fixed structure with steel fishplate bar welding copper gasket plate.
Background technology
The effect that spiral welded pipe produces unit plate receiving device be leveling after steel plate head, tail trim, then the method for band steel toe tail welding docked.During welding, arrange copper pad below band steel joint, its effect is heat radiation and can improves the surface quality of welding.As shown in Figure 1, in the plate receiving device of current use, copper pad is fixed on the clamping device of plate receiving device by hexagon socket head cap screw, due to frequent welding, the copper pad surface contacted with the strip often is piled up weldering meat or is burnt when welding, and just needs to change after using a period of time; But because the upper surface of copper pad is working surface, therefore adopt hexagon socket head cap screw to coordinate fixing mode with dormant bolt hole, copper pad can only use once; Because copper piece cost is higher, and general plate receiving device overall length 2 meters, copper pad needs 40 bolts to fix altogether, and during replacing, demounting bolt is wasted time and energy, and causes wearing and tearing to need redrilling tapping owing to frequently changing to the screwed hole of former clamping device; Therefore, the fixed form of the copper pad adopted at present has maintenance trouble, replacing construction is long, the shortcoming that copper pad service life is short, cost is high.
Summary of the invention
The utility model provides a kind of fixed structure with steel fishplate bar welding copper gasket plate, the mode combined by being welded and fixed baffle plate and bolt fixed dam is fixed copper pad, not only fixing reliable, dismounting and change convenience, the two-sided utilization of copper pad can also be realized, its service life can be significantly improved, reduce production cost.
In order to achieve the above object, the utility model realizes by the following technical solutions:
With a fixed structure for steel fishplate bar welding copper gasket plate, comprise copper pad, be welded and fixed block and briquetting fixed by bolt, copper pad is fixed briquetting be fixed on clamping device weld pad pallet frame by being welded and fixed block and bolt; Be welded and fixed block and bolt to fix briquetting and be separately positioned on the longitudinal both sides of copper pad, the corresponding two sides of copper pad are along the symmetrical chamfering of horizontal median axis, and chamfer angle is 45 ~ 60 °; Be welded and fixed block, bolt fixes the side that briquetting matches with copper pad and be inclined-plane, angle of inclination and copper pad upper bevel angle adapt; Dormant bolt hole briquetting being also provided with and matching with hexagon socket head cap screw fixed by bolt.
The summit of described copper pad chamfering is in horizontal median axis.
Described copper pad, be welded and fixed block and bolt and fix briquetting and be segmentation structure, and be welded and fixed block, the length that briquetting fixed by bolt is equal with the length of the copper pad that matches.
Compared with prior art, the beneficial effects of the utility model are:
1) mode combined by being welded and fixed baffle plate and bolt fixed dam is fixed copper pad, fixing reliable, dismounting and change is convenient, be suitable for very much spiral welded pipe and produce on the plate receiving device of unit;
2) the two-sided utilization of copper pad can be realized, its service life can be significantly improved, reduce production cost;
3) improve the condition of work of hexagon socket head cap screw, because copper pad temperature is high in original structure, hexagon socket head cap screw stressing conditions is complicated, and deflection is large, and hexagon socket head cap screw dismounting difficulty after distortion, the screwed hole on easy butt welding backing plate stand damages; In the utility model, to be bolted the wedge surface of briquetting stressed for hexagon socket head cap screw, and hexagon socket head cap screw deflection is little, easily dismantles, and can not cause damage in double thread hole.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
Seeing Fig. 2, is structural representation of the present utility model.A kind of fixed structure with steel fishplate bar welding copper gasket plate of the utility model, comprises copper pad 3, is welded and fixed block 2 and briquetting 4 fixed by bolt, and copper pad 3 is fixed briquetting 4 be fixed on clamping device weld pad pallet frame 1 by being welded and fixed block 2 and bolt; Be welded and fixed block 2 and bolt to fix briquetting 4 and be separately positioned on the longitudinal both sides of copper pad 3, the corresponding two sides of copper pad 3 are along the symmetrical chamfering of horizontal median axis, and chamfer angle is 45 ~ 60 °; Be welded and fixed block 2, bolt fixes the side that briquetting 4 matches with copper pad 3 and be inclined-plane, angle of inclination and copper pad 3 upper bevel angle adapt; Dormant bolt hole briquetting 4 being also provided with and matching with hexagon socket head cap screw 5 fixed by bolt.
The summit of described copper pad 3 chamfering is in horizontal median axis.
Described copper pad 3, be welded and fixed block 2 and bolt and fix briquetting 4 and be segmentation structure, and be welded and fixed block 2, the length that briquetting 4 fixed by bolt is equal with the length of the copper pad 3 that matches.
The using method of a kind of fixed structure with steel fishplate bar welding copper gasket plate described in the utility model is as follows:
