Abstract
The invention relates to a novel method for manufacturing an ultra-large type wind turbine blade rib plate die. The die consists of bonding corners, rib plates, die steel frames, glass shell dies and heating layers. During manufacturing, the die steel frames are manufactured first, two sides of each shell die are cut to form contours according to the sizes of the rib plates, and the glass shell dies are welded at the corresponding positions of the die steel frames; the heating layers and vacuum tubes are arranged underneath the glass shell dies and are used for heating and vacuum processing during manufacturing of blade rib plates; and die steel plates are manufactured by a method of spot welding and splicing, base plate spot welding and exterior coating of glass reinforced plastic in the length directions of the glass shell dies. The method has the advantages that the dies which are manufactured by using the steel plates can transfer heat quickly and uniformly, the surfaces of the dies are not deformed and high in flatness, the blade rib plates are perpendicular to the axis direction and can be adjusted, and the problem of air leakage of the connection part of a die which is manufactured by using the ultra long blade rib plate all-steel plates is solved by the method of spot welding, base plate spot welding and exterior coating of glass reinforced plastic simultaneously; the inclination angles of the bonding corners can be adjusted slightly; sheet steel is adopted, a tip part can be bent; and the method is suitable for manufacturing complex blade rib plate dies.
Description
Technical field
The present invention relates to a kind of preparation method of novel ultra-large type wind electricity blade gusset mould.
Background technology
Ultra-large type wind-powered blade mold refers to that length is greater than 50m, and one-sided weight is greater than the former of 40t.At present, the mould of the blade of domestic production manufacture is all overall manufacture.For security consideration, the length, height etc. to transporting cargo such as railway, highway is all restricted, and this just causes former transport difficult, the problem that cost of transportation is higher.Meanwhile, due to blade mold enormous size, make Making mold space requirement also comparatively large, higher to production space requirement.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of novel ultra-large type wind electricity blade gusset mould.
The preparation method of the novel ultra-large type wind electricity blade gusset mould that the present invention proposes, described mould is made up of gluing angle 1, gusset 2, mould steelframe 3, zone of heating 4 and version of die for glass envelop 5.Gusset 2 is arranged in version of die for glass envelop 5, version of die for glass envelop material adopts steel plate, steel plate adopts spot welding to add backing plate spot welding and sticks with paste fiberglass method outward, below version of die for glass envelop, surrounding is fixed with square steel, version of die for glass envelop 5 is provided with zone of heating 4 and vacuum tube one end below, and version of die for glass envelop 5 is welded in the relevant position of mould steelframe 3, and version of die for glass envelop 5 edge direction inclination certain angle forms gluing angle 1, bottom, gluing angle 1 is provided with gluing angle 1 fiberglass, and the vacuum tube other end connects pumped vacuum systems through described fiberglass; Its preparation method is as follows:
The making of mould steelframe 3 is first completed during making, then version of die for glass envelop steel plate is cut out its appearance profile by the size of blade gusset requirement in both sides, be welded to connect with it at the square steel of its lower panels surrounding 80X80X4, strengthen its rigidity, avoid version of die for glass envelop steel plate deformed.Version of die for glass envelop 5 lays zone of heating 4 and vacuum tube below, heats and is arrived on version of die for glass envelop steel plate 5 by vacuum tube carry out vacuum pumping for the zone of heating 4 when making gusset 2.Subsequently version of die for glass envelop 5(is contained zone of heating) be welded on the relevant position of mould steelframe, then in the relevant position, both sides of version of die for glass envelop 5 length direction, the sheet metal with certain altitude is welded on above version of die for glass envelop 5 to plate splicing on demand respectively, sheet metal toward the direction inclination certain angle near version of die for glass envelop 5 edge, is convenient to gusset product delivery after having welded plate.The type sheet metal referred to as gluing angle 1; Gusset mould required when laying compound glass Steel material and obtain making blade after fiberglass carries out vacuumizing process below by the vacuum tube through through hole in the middle of gluing angle 1, both sides.Described gluing angle steel-sheet height is between 40mm-160mm; The described angle of inclination, direction near version of die for glass envelop edge is between 85 degree of-130 degree.
Advantage of the present invention is: adopt the version of die for glass envelop of whole steel sheet material have heat transfer fast and evenly, surface is indeformable and flatness is high, blade gusset perpendicular to plurality of advantages such as axial dimension are adjustable, be coated with fiberglass pattern outward solve overlength blade gusset employing whole steel sheet making version of die for glass envelop junction leakage problem by adopting spot welding to add backing plate spot welding simultaneously; Adjustment slightly also can be done in the angle of inclination at gluing angle, because version of die for glass envelop can also have bending owing to adopting thin layer steel plate in tip, is applicable to complicated blade gusset Mold Making.
