Manufacturing die of unmanned aerial vehicle blade

Abstract

The invention discloses a manufacturing die of an unmanned aerial vehicle blade. The manufacturing die comprises an upper die, a lower die and positioning pins I; the lower die cuts cutting blocks rightwards from the left reflex angle zero-degree line position on the front wall of a lower die cavity corresponding to the trailing edge of the blade, the right end face of each cutting block corresponds to the starting position of the arc transition of the tail end of a blade body and the tail end of a blade tip, the lower end face of each cutting block is lower than the lowest point of the intersection line of the front wall of the lower die cavity and the bottom face of the lower die cavity, the rear end face of each cutting block are the inner end face of the front wall of the lower die cavity, and the front end face of each cutting block is not larger than the outer end face of the front wall of the lower die cavity; the symmetrical positioning pins I are arranged at the left end and the right end of the upper end face of a lower die block, positioning holes I are formed in the lower end face of the upper die, and after die is closed, the positioning pins I are located in the positioning holes I correspondingly; fixing mechanisms are evenly arranged on the front walls and the rear walls of the upper die block and the lower die block, and after die is closed, the upper die blockand the lower die block are fixed together through the fixing mechanisms. The manufacturing die is easy to manufacture, low in manufacturing cost, high in manufacturing precision and low in rejectionrate; and the unmanned aerial vehicle blade manufactured by the manufactured die is easy to demold, low in manufacturing cost and high in blade quality.

Description

technical field [0001] The invention belongs to the technical field of making drone blades, and relates to a mold for making drone blades. Background technique [0002] UAV is an emerging industry, which is widely used in military and civilian fields. The blades of the UAV are the main moving parts to meet the power of the UAV. With the development of my country's aviation industry, drones have become one of the new development industries of the aviation industry. [0003] Generally, the blade is made by a mould. The blade mold is generally separated on the curved surface formed by the line connecting the largest contour line of the front and rear edges of the blade body. According to the placement position, it is divided into an upper mold and a lower mold. Due to the requirements of high performance and fast speed of the UAV, the blade is a sheet structure, and the length of the blade is small, generally about 1-3 meters, so the twist angle of the blade body is relativel...

AI Technical Summary

Problems solved by technology

The positioning pin is mechanically formed with the positioning sleeve, and the forming process is complicated

The leaf body of the blade is integrated with the petiole when the mold is formed; when the mold is formed, the positioning of the blade is processed by machining, and the angular positioning deviation is large. On the other hand, it is not easy to ensure the consistency of the installation angle between the blade body and the positioning pin, which leads to the poor consistency of the angle between the blade positioning pin and the blade body, and it is difficult to ensure the balance and safety of the high-speed rotating blade
