Abstract
The invention relates to a tool for one-step welding forming of flange flatness and taper. The tool comprises a tower shell ring flange. The tower shell ring flange is connected with a tool flange through connecting bolts and nuts. A bolt hole corresponding to the tower shell ring flange is formed in the tool flange. A plurality of connecting blocks are distributed outside the tool flange. The tool has the advantages that one-step welding forming of flange flatness and taper is guaranteed, and production efficiency is improved.
Description
Technical field
The present invention relates to a kind of wind-power electricity generation special-purpose field, particularly an a kind of welding fabrication frock for planeness of flange and tapering.
Background technology
In wind power tower drum installation process, generally all can adopt flange to connect, therefore need to welded flange be installed respectively in the both sides of tower cylinder, but while being flange and barrel soldering in welding process, impact due to the thermal stress of welding, can cause flange to turn up, produce welding deformation, thereby affect the installation of tower drum flange.
Summary of the invention
The object of the invention is in order to overcome above deficiency, provide a kind of assurance planeness of flange and tapering a welding fabrication, a welding fabrication frock for planeness of flange and tapering of enhancing productivity.
Object of the present invention is achieved through the following technical solutions: an a kind of welding fabrication frock for planeness of flange and tapering, comprise pylon shell ring flange, pylon shell ring flange is connected with frock flange with nut by connecting bolt, frock flange is provided with and bolt hole corresponding on pylon drum flange, and the outside of frock flange is distributed with a plurality of contiguous blocks.
Further improvement of the present invention is: one end introversion that described pylon shell ring flange is connected with frock flange, and frock flange flare, pylon shell ring flange matches with frock flange.
Further improvement of the present invention is: 0～0.5 ° of described frock flange flare, 0～0.5 ° of pylon shell ring flange introversion.
The present invention compared with prior art has the following advantages: the joint face flatness processing request of frock flange is consistent with pylon shell ring flange, the technical parameter of joint face upper bolt hole is also consistent with flange, according to reversible deformation principle, joint face is processed with the amount of turning over (evagination) in advance.Together with frock being joined with bolts with flange before flange welding, the rigidity of logical frock self restriction flange welding deformation, thus guarantee planeness of flange and welding fabrication of tapering, greatly improved production efficiency.
accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
Number in the figure: 1-pylon shell ring flange, 2-connecting bolt, 3-nut, 4-frock flange, 5-bolt hole, 6-contiguous block.
the specific embodiment:
in order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
As Fig. 1 shows the specific embodiment of an a kind of welding fabrication frock for planeness of flange and tapering of the present invention, comprise pylon shell ring flange 1, pylon shell ring flange 1 is connected with frock flange 4 with nut 3 by connecting bolt 2, frock flange 4 is provided with and bolt hole 5 corresponding on pylon drum flange 1, the outside of frock flange 4 is distributed with a plurality of contiguous blocks 6, one end introversion that pylon shell ring flange 1 is connected with frock flange 4, frock flange 4 flares, pylon shell ring flange 1 matches with frock flange 4, 0～0.5 ° of frock flange 4 flare, 0～0.5 ° of pylon shell ring flange 1 introversion.
Welding fabrication frock of the present invention is according to the specifications design of pylon shell ring flange 1, the joint face flatness processing request of frock flange 4 is consistent with pylon shell ring flange 1, the technical parameter of joint face upper bolt hole is also consistent with flange, according to reversible deformation principle, joint face is processed with the amount of turning over (evagination) in advance.Before being welded with flange and shell ring circumferential weld, together with frock is joined with bolts with flange, the rigidity restriction flange welding deformation of logical frock self, thereby guarantee welding fabrication of planeness of flange and tapering, greatly improved production efficiency, before being welded with flange and shell ring circumferential weld, flange is connected fastening with frock flange, flange is had after an actual reversible deformation, then the circumferential weld of shell ring and flange is welded with, remove again frock flange after waiting weld inspection qualified, cooling.
