Description
Technical field
The present invention relates to technical field of wind power generation, in particular to a kind of blade mold and its molding method for turning.
Background technique
Wind power generating set is the equipment for converting wind energy into electric energy, usually by the main portion such as tower, blade and generator
Part composition is rotated using wind-force band movable vane piece, then drives generator rotary electrification.
Production blade is needed using blade mold at present, blade mold usually by mold steelframe, suction surface housing mould and
Pressure face housing mould composition is made suction surface shell using suction surface housing mould, is made and pressed using pressure face housing mould
After power face-piece body, then molding assembly is carried out to the two, completes the production of blade.
Existing blade mold uses upper and lower clamping system, i.e., in suction surface housing mould and pressure face housing mould
It is lower die that it is motionless, which to be fixed on ground, for one, and another one is then upper mold, and overturning 180 degree is molded after being placed in the top of lower die.
Specifically, lower die is fixedly connected with the supporter of turnover mechanism, the flip body of upper mold and hydraulic turnover mechanism is solid
Fixed connection.In original state, upper and lower mould is horizontally arranged on the ground, and turnover mechanism flip angle is 0 degree at this time.Need into
When row molding, turnover mechanism overturns 180 degree, and upper mold is overturn to the top of lower die, and is declined under self weight with lifting body, pastes
The land area of nearly lower die, is then locked with retaining mechanism.
The process of die sinking then with mold it is substantially opposite, first release retaining mechanism, by lifting body by upper mold jack up to
Certain distance, then by turnover mechanism reverse flip 180 degree, upper mold overturning is restored to initial level placement location.
Existing upper and lower clamping system has the following problems:
(1) upper mold is placed by turnover mechanism cantilever, and upper mold is outstanding by flip body in initial position and switching process
Arm support, steel frame deformation is big, and frp layer is easy to cause to deform；
(2) turnover mechanism needs to overturn 180 degree, and each turnover mechanism generally assembles two overturning oil cylinders, there is dead point
Position is easy to cause to deform because of impact or destroy；
(3) turnover mechanism assembly concentricity requires high, and operation synchronization accuracy requirement is high, designs and produces and maintenance cost height；
(4) turnover mould-matching process about 7.5 minutes, take a long time, production efficiency is lower.

On the second support base 231.
The process of leaf production is illustrated with reference to the accompanying drawing, to further illustrate the specific structure of blade mold
And molding method for turning.
When making blade shell, blade mold is first in original state shown in FIG. 1, as shown in Figure 1, first shell mould
Tool 1 is placed horizontally in the first die supports and mold 11 and second shell mold 2 is placed horizontally in the second die supports and mold 21, at this time
First overturning actuator 12 and the second overturning actuator 22 are in retrieving position, first shell mold 1 and second shell mold 2
Installation site according to blade mold design width value be determined.
In the initial state complete blade shell production, and complete blade web lifting after, molding step need to be carried out.
At this point, the first overturning actuator 12 of starting and the second overturning actuator 22 realize extending action, by first shell mould
Tool 1 and second shell mold 2 turn in opposite directions to be turn 90 degrees, specific as shown in Figure 2.At this point, the first supporting mechanism and second can be passed through
Level height after support mechanism overturns first shell mold 1 and second shell mold 2 is adjusted, to guarantee the two height one
It causes, so that it is guaranteed that the accuracy of die-closed position.
It, need to be using displacement adjustment device to first shell mold 1 and second shell mold 2 next, before molding
Relative distance is adjusted, as shown in figure 3, jacking actuator 25 first stretches out, will jack the peace of seat 251 release and retaining mechanism
241 docking are shelved, actuator 242 is then locked and protracts, driving locking connecting rod 243 acts, and the latch hook for locking connecting rod 243 is pushed into
Withhold the locking bar 252 on jacking seat 251.
Then jacking actuator 25 acts, and pushes second shell mold 2 to first shell mold 1 side, with first shell
Mold 1 close to, be ready for molding, it is specific as shown in Figure 4,5.
Terminate in molding, after completing leaf production, first shell mold 1 and the die sinking of second shell mold 2 need to be resetted,
The operating procedure of die sinking and molding are substantially opposite.Specifically, jacking actuator 25 is retracted first, thus by second shell mould
Tool 2 retracts the position of original state, realizes that second shell mold 2 and first shell mold 1 are detached from.
Then the second overturning actuator 21 retracts, and by 90 degree of 2 reverse flip of second shell mold, returns to original state position
It sets.
Blade is hung into mold, then starts the first overturning 12 retraction movement of actuator, first shell mold 1 is reversely turned over
It turn 90 degrees, returns to original state position.
When making blade shell using the blade mold of the present embodiment, first shell mold and second shell mold are horizontal
It is placed in corresponding die supports and mold, when molding, is acted together by overturning actuator, by first shell mold and second shell
Mold is synchronized to turn in opposite directions and be turn 90 degrees.The present embodiment has abandoned traditional clamping system up and down, proposes an a kind of completely new left side
Right clamping system has apparent advantage, is mainly manifested in:
(1) turnover mechanism structure is simple, easy for installation, and overturning concentricity requirement is lower, has saved the manufacturing and maintenance
Cost；
(2) flip angle is only 90 degree, and dead-centre position is not present in overturning actuator, and switching process is more steady；
(3) on the ground, hinged between housing mould and die supports and mold, entire turnover mechanism is without cantilever for turnover mechanism installation
Structure, housing mould deform small in switching process；
(4) switching process is changed to left and right mold by traditional upper mold overturning and overturns together, and burn close time shortens half, mentions
High production efficiency.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
