Front double-hydraulic-cylinder wind power blade automatic mold closing device

Abstract

The invention relates to a wind power blade automatic mold closing device, in particular to a front double-hydraulic-cylinder wind power blade automatic mold closing device which comprises an upper mold and a lower mold which are used for manufacturing wind power generator blades and further comprises a turnover mechanism fixed to a base. The upper die and the lower die are arranged on one side of the base; the turnover mechanism comprises a main hydraulic cylinder, a main rocker arm, an auxiliary hydraulic cylinder and an auxiliary rocker arm; the output end of the main hydraulic cylinder is in transmission connection with the main rocker arm; the main rocker arm is rotationally connected with the base; the output end of the auxiliary hydraulic cylinder is in transmission connection with the auxiliary rocker arm; the auxiliary rocker is rotationally connected with the main rocker; the upper die is fixed on the auxiliary rocker arm, and the lower die is fixed on the base. Compared with the prior art, on the premise of ensuring the reliability, the brand-new automatic overturning and mold closing device for the wind power blade is provided from the perspectives of being stable in stress, saving space and reducing the later maintenance difficulty.

Description

technical field [0001] The invention relates to an automatic mold clamping device for wind blades, in particular to an automatic mold clamping device for wind blades with front double hydraulic cylinders. Background technique [0002] Wind blades are one of the core components of wind turbines, accounting for about 15%-20% of the total cost of wind turbines. The quality of their design will directly affect the performance and benefits of wind turbines. Wind blades are mainly lifted and flipped by mechanical cranes to realize demoulding and mold closing, but the process is discontinuous, the movement is not stable, the matching accuracy of the upper and lower molds is poor, and when the center of gravity of the blade mold passes through the center of rotation, there will be a large Vibrations and shocks are likely to cause safety accidents; in addition, manual control is difficult and the productivity is low. The automatic flip mold clamping device works smoothly and can be ...

Problems solved by technology

However, this device takes up a lot of space under the steel frame, and needs to be replaced with a steel frame that matches the phase. It cannot be used well with the original steel frame of the factory, which greatly increases the cost of the factory.

At the same time, the equipment has a hydraulic cylinder located under the steel frame, which is not conducive to the later maintenance of the hydraulic cylinder and increases the difficulty of later maintenance

At the same time, this type of equipment occupies a large space outside the steel frame.
