Abstract
The utility model relates to 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.The utlity model has and guarantee planeness of flange and welding fabrication of tapering, the advantage of enhancing productivity.
Description
Technical field
The utility model 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 purpose of this utility model is in order to overcome above deficiency, provides 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.
The purpose of this utility model 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 utility model 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 utility model is: 0～0.5 ° of described frock flange flare, 0～0.5 ° of pylon shell ring flange introversion.
The utility model 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 utility model;
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 understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1 shows the specific embodiment of an a kind of welding fabrication frock for planeness of flange and tapering of the utility model, 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 described in the utility model 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.
