Description
Technical field
The present invention relates to a kind of stack-press device, be specifically related to a kind of stack-press device that integral body laminates the stator silicon steel sheet of large-scale wind driven generator that is used for.
Background technology
In order to respond the call of national energy-conserving and environment-protective, development and use clean energy resource, the application of wind-driven generator is popularized just gradually.For example: Chinese patent literature notification number CN200996357Y discloses a kind of wind-driven generator, comprises fan blade, generator, rechargeable battery, inverter controller and underframe.
According to the specification requirement of aerogenerator stator, stator comprises: main shaft, be located at front end-plate and end plate on the main shaft; Silicon steel sheet is formed by stacking and is located between front end-plate and the end plate by layer disjunction, evenly be distributed with a plurality of stator pull bars on the internal perisporium of silicon steel sheet, the edge of forward and backward end plate is provided with and the corresponding pull bar installing hole of each stator pull bar, and the two ends of each stator pull bar pass from the pull bar installing hole of described forward and backward end plate respectively.
Wherein, necessary no gap between each silicon steel sheet that laminates mutually, and in the prior art, for the stator of large-scale wind-driven generator, especially diameter is at 4 meters and above stator, and the ring-shaped silicon steel sheet on the stator has about 1100 layers, the thick 0.5mm of each silicon steel sheet, whole stator weighs about 20 tons.Simultaneously, for easy for installation, every layer of silicon steel sheet is divided into multistage, and the segments of each layer is identical, for example: 24 sections, every section radian is 15 °, and when laying, the laying of staggering of each layered suture; Be provided with 48 positioning tie bars between the front end-plate of stator and the end plate, be used for welding mutually with described front end-plate, end plate and the silicon steel sheet that laminates mutually.Therefore these silicon steel sheets are laminated and weld, the specification requirement in above-mentioned to satisfy " no gap " and the assembling requirement of stator obviously are technical barriers.
If thinking routinely: adopt 24 and be arranged in the oil cylinder that covers, laminating from top to bottom by bearing ring, is about 1600 tons, therefore owing to need applied pressure, described loam cake must be all very firm abundant, can bear the moment of flexure of pressure dwell to guarantee loam cake; Thisly cover the consequence that structure caused that 24 oil cylinders are set on abundant and be: the opening that being used to of can reserving welded stator is very little, cause construction space also very little, so can't carry out welding job, thereby can't produce the stator that qualified large-scale wind driven generator is used.
Summary of the invention
Technical problem to be solved by this invention provides a kind of stack-press device, is used for the satisfied needs that the silicon steel sheet of large-scale wind driven generator stator is laminated and welds.
For solving the problems of the technologies described above, the invention provides a kind of stack-press device, comprising: base, a plurality of pull-down oil cylinder, bearing ring and loam cake; During use, described base is provided with the main shaft of stator to be laminated, and main shaft is provided with front end-plate; Described bearing ring and loam cake are used to be arranged on the front end-plate top of stator, and on be covered on the bearing ring inboard; Described each oil cylinder is fixed on the outer wall of base, and the piston rod of each oil cylinder and bearing ring are fixedly linked.
In the technique scheme, described loam cake comprises: the pull bar locating ring of being located at the main shaft retainer ring of main shaft upper end, linking to each other by 3 to 12 tie-beams with the main shaft retainer ring; The pull bar locating ring is provided with a plurality of pull bar installing holes.
One side of described pull bar installing hole is provided with the last clamp of the position that is used to proofread and correct each stator pull bar upper end; Described base is provided with ring flange, and the edge of ring flange is provided with the following clamp of the position that is used to proofread and correct each stator pull bar bottom.
The present invention has positive effect: in (1) stack-press device of the present invention, each oil cylinder is fixed on the outer wall of base, and the piston rod and the bearing ring of oil cylinder are fixedly linked, and in use, the piston rod of each oil cylinder pulls down bearing ring simultaneously, and reliability is better; Simultaneously, because this moment, loam cake was not laminated pressure, and only be to be the location of the stator pull bar on the stator, therefore loam cake can design relatively lightlyer, cover the opening that to open enough big welding usefulness thereby make, because do not have other shelters, the staff can enter by this opening and carry out welding job in the stator.Adopt seamless steel pipe to be connected between the Hydraulic Station of oil cylinder voltage supply and the oil cylinder, because oil cylinder need not dismounting after being installed on the base, the generation of problems such as the oil leakage that has produced when having avoided dismantling oil cylinder, air inlet, exhaust.(2) in the stack-press device of the present invention, the pull bar locating ring of loam cake is provided with a plurality of pull bar installing holes.When assembling stator, each stator pull bar is inserted and is located on the stator by the pull bar installing hole, when welding, each stator pull bar is welded on the front end-plate of stator simultaneously by each pull bar installing hole.(3) in the stack-press device of the present invention, last clamp and following clamp are respectively applied for the position of proofreading and correct each stator pull bar upper end and bottom, thereby the stator pull bar is close on the internal perisporium of silicon steel sheet, in convenient welding, further be beneficial to each stator pull bar is accurately located, radially all keeping alignment to guarantee silicon steel sheet.(4) in the stack-press device of the present invention, main shaft is fixedly installed on the spindle hole of base central authorities, is beneficial to the fixed stator main shaft, is beneficial to end plate, silicon steel sheet and front end-plate are installed; In addition, guaranteed when silicon steel sheet is laminated that whole stator has stability preferably, is beneficial to the work of laminating.(5) in the stack-press device of the present invention, front end-plate and stator main shaft are unfixing, and the many root posts on the base are provided with spring, are used for upspringing before laminating and locating front end-plate, reserve enough spaces for the placement of silicon steel sheet.(6) in the stack-press device of the present invention, the main shaft retainer ring of loam cake matches with the upper end of described main shaft, so that loam cake is fixed on the main shaft, to stablize loam cake.(7) in the stack-press device of the present invention, the pressure ring step on the medial surface of bearing ring is used to that loam cake is installed or carries the pull bar locating ring of loam cake when the demoulding, is in level all the time to guarantee loam cake; When laminating, the lower surface of pressure ring step laminates the root of front end-plate (being the edge), to guarantee to laminate effect simultaneously.The top bolt of stator main shaft is connected with shrouding disc, and the external diameter of shrouding disc is not less than the open-topped internal diameter of described main shaft retainer ring.During the demoulding, unclamp the locating piece of described upper and lower clamp earlier, unload the upright nut at each column top, control each oil cylinder jack-up bearing ring then, because the drive of the pressure ring step on the bearing ring, the loam cake quilt is jack-up together, go up simultaneously tops and withstand described shrouding disc, make shrouding disc pulling stator main shaft, and then make together jack-up of bearing ring, loam cake and whole stator quilt, thereby finish demoulding work.
