Description

Technical Field

[0001] The utility model belongs to the technical field of fan blade main beam molds, and in particular relates to a fan blade main beam forming mechanism. Background Art

[0002] At present, wind turbine blades are developing in the direction of "large", and large blades have higher requirements for production quality and weight. The main beam is a key component in blade production. Usually, the main beam of a large blade is difficult to be formed in one time due to the thick cloth layer and large width, and there is a risk of impurities and auxiliary materials being mixed in during the pouring molding process. In order to reduce the risk of quality defects in blade manufacturing and improve the quality stability and reliability of new products, the utility model provides a mold that can effectively prevent impurities from entering the mold, and the auxiliary materials will not affect the pouring.

[0003] To this end, a wind turbine blade main beam mold with a notice number of "CN211807263U" is disclosed, which includes a positioning plate, a rib is provided on both sides of the positioning plate, and a guide net, a porous membrane and a demoulding cloth are laid in sequence from the bottom in the cavity surrounded by the positioning plate and the rib, wherein the porous membrane and the demoulding cloth are U-shaped and are both located on the guide net, and the main beam product is placed in the demoulding cloth, and the porous membrane and the demoulding cloth openings are simultaneously facing a rib, so that the three auxiliary materials of the porous membrane, the guide net and the demoulding cloth are integrated, and the porous membrane and the demoulding cloth openings face one side, which prevents the auxiliary materials from being clamped into the mold without affecting the pouring work. The utility model can effectively prevent impurities or auxiliary materials from being clamped into the pouring mold during the main beam pouring process, thereby reducing product quality defects and ensuring the stability and reliability of the pouring process.

[0004] However, for the above-mentioned wind turbine blade main beam mold, although the upper and lower layers of demoulding cloth and the porous membrane are both opened on both sides, the two sides can be easily clamped in the mold during the injection process, which greatly reduces this risk, there are still the following obvious defects during use: when the above-mentioned mold is used to close the mold for wind turbine blade molding, a gantry hanger is used to close the mold of two layers of blades. During the hoisting and closing of the mold, the template is easily shaken due to the suspension, and the two templates cannot be accurately closed, which easily leads to the problem of mold offset.

[0009] Preferably, a pneumatic jacking block is fixed to the top of the piston rod of the lifting cylinder arranged on one side of the fixed template and is lifted up at the same time as the stable mounting seat on the lifting cylinder on the other side of the fixed template, so as to lift the flip template away from the fixed template.

[0010] Preferably, positioning seats are equidistantly provided on one side of the fixed template, and a positioning hole is provided at the midline position of the end of the positioning seat, which is adapted to be plugged into the positioning pin for mold closing positioning, so that the two templates can remain stable and firm after the mold closing process to avoid position deviation.

[0013] By arranging the lifting cylinders on both sides of the fixed template and the top block fixed on one side of the flipping template, after the fixed template and the flipping template are combined to assemble the fan blades, the lifting cylinders on both sides of the fixed template can push the pneumatic top block and the stable mounting seat to move up respectively. When the flipping template is subjected to the upward pushing force, the flipping template is separated from the formed fan blades, and the flipping motor group is used to drive the flipping template to flip to one side at an angle to the end of the step template, thereby avoiding the problem of shaking and hitting the surface of the fan blade during the demoulding process of the template hoisting, thereby improving the stability of the flipping template demoulding and flipping.

Lifting cylinders 4 for lifting and demolding the flip template 3 are equidistantly provided on both sides of the fixed template 2, so that the flip template 3 can maintain a stable rise without friction and collision with the surface of the fan blade. The lifting cylinder 4 provided on one side of the fixed template 2 is provided with a The L-shaped stable mounting seat 5 allows the stable mounting seat 5 to be supported by the lifting cylinder 4 on one side, which not only maintains stability but also facilitates the demoulding of the flip template 3. The inner bottom end of the stable mounting seat 5 is provided with a flipping motor group 6 for driving the flip template 3 to flip and open. The multiple designs of the flipping motor group 6 can enable multiple flipping motor groups 6 to rotate simultaneously to generate a larger flipping torque for flipping the flip template 3, and can ensure the stability of the flipping. The rotating shaft of the flipping motor group 6 is rotatably connected to the inner side of the upward extending end of the stable mounting seat 5 through a bearing and is connected to a flip frame 7 for flipping the flip template 3, which can enable the flip template 3 to be flipped and play a protective role in the flipping process of the flip template 3.

[0020] The stabilizing flip rod 8 is evenly provided with the outwardly extending stabilizing flip rod 8 on one side end of the flipping frame 7. The stabilizing flip rod 8 is made of hard steel material with anti-bearing capacity to ensure that there will be no breakage during flipping. The stabilizing flip rod 8 is sleeved and fixed on the rotating shaft of the flipping motor group 6 to drive the stabilizing flip rod 8 to flip the flipping frame 7.

This mold-closing method can prevent the flipping template 3 from shaking during the flipping process and achieve the effect of precise mold-closing. When the flipping template 3 is subsequently demolded, the lifting cylinders 4 on both sides of the fixed template 2 use the top block 10 and the stable mounting seat 5 to push the entire flipping template 3 vertically upward, so that the flipping template 3 can be safely separated from the fan blade main beam, and the occurrence of collision can be effectively avoided.
