The invention discloses a centrifugal wind wheel blade manufacturing method and stamping mold, and belongs to the technical field of centrifugal wind wheels. A strip-shaped rolled material with the width similar to the length of a blade is used and is fed to the position between an upper mold part and a lower mold part through a rolling roller, according to the mold, mold cavities which are arranged in the advancing direction of the rolled material and correspond to a plurality of continuous stations are integrated on the mold, and in the one-time stroke process of downward stamping of the upper mold part, the working procedures of stamping a transverse technology limiting groove, stamping a technology guide hole, stamping heads at the two ends of blades, stamping the blades, stamping the heads at the two ends of the blades so as to enable the heads to be bent into V shapes, stamping the heads of the two ends of the blades so as to enable the heads to be bent into Z shapes, stamping the blades so as to enable the blades to be bent into R flow guide arc shapes, stamping and bending the heads of the two ends of the blades by 90 degrees along the reverse flow arc shapes so as to enable clamping feet to be molded, and blade stamping down and waste cutting off; before the secondary stroke of the downward stamping of the upper mold part, the strip-shaped rolled material is fed by a certain distance by the rolling roller, and the distance is equal to the distance between two stations. According to the method and mold, the efficiency and the machining precision are greatly improved.
Description
technical field [0001] The invention belongs to the technical field of centrifugal wind rotors, and in particular relates to a manufacturing method of centrifugal wind rotor blades and stamping dies thereof. Background technique [0002] The centrifugal wind wheel uses the motor to drive the blades to rotate at high speed, and the blades drive the air to rotate at high speed. When the air rotates at high speed, centrifugal force will be generated, and the air will move from the center of the wind wheel to the edge under the action of centrifugal force. The blades of the centrifugal wind rotor in the prior art are evenly distributed along the circumferential direction of the wind rotor. As the blades rotate, the airflow on the blades moves radially along the fan shaft. In the prior art, when manufacturing blades, the raw materials are usually first punched into pieces with the same length as the blades, and then the clips at both ends of the blades and the blades are stamped...
