Embodiment Construction
[0030] In order to further illustrate the present invention, introduce below in conjunction with accompanying drawing of description:
[0031] The production process of motor aluminum fan blades, specifically in the following steps:
[0032] 1) material selection, select aluminum plate;
[0033] 2) Through computer typesetting, nest cutting, and water cutting into blanks, 3mm is reserved for one side, 15mm for the end of the blade root, and 10mm for the process head of the blade crown;
[0034] 3) Milling the blade root, clamping the tip of the blade crown by a milling machine, milling the blade root to form the precise reference plane of the blade;
[0035] 4) Center hole, a round shaft is clamped on the center turntable of the milling machine, the positioning hole in the middle of the positioning tool is set on the round shaft, the base of the positioning tool is fixed on the center turntable of the milling machine by screws, and then the blank is installed in the positioni...

The invention particularly relates to a production technology for a motor aluminum fan blade. The production technology comprises the steps that a material is selected, and an aluminum plate is selected; computerized typesetting is performed, and suit cutting is performed; a blade root is milled; a center hole is drilled, drilling is started, a center rotating disc is rotated by 180 degrees, the end face of the blade root is arranged horizontally, and positioning drilling is performed on the basis of the same method; an ejector pin is used for abutting against a center hole of the blade tip end of a blank, the other end abuts against a center hole of the blade root end through an ejector pin in the middle of a one-jaw wrench, and the one-jaw wrench clamps the large blade root end; a blade passage portion of the blank is milled; whether the blank is qualified or not is judged by measuring a molded line of the blade portion of the blank through a measuring gauge, and if the blank is disqualified, milling parameters are adjusted till the blank is qualified; a reserved technological head of the blade tip is cut to obtain the finished motor aluminum fan blade. The production technology has the beneficial effects that the technology is perfect, the aluminum plate obtained through extrusion molding is selected, and suit cutting can be performed on the aluminum plate, so that materials are greatly saved; water cutting is performed on the aluminum plate to perform suit cutting to form the shape of the blade, so that the production technology is economical and affordable; the blade is clamped through the one-jaw wrench, so that a workpiece is conveniently positioned and clamped; and the center line of the blade is made to coincide with the center line of a machine tool through the one-jaw wrench, so that machining precision is ensured.
Description
technical field [0001] The invention relates to the field of wind blade production, in particular to a production process of aluminum wind blades for motors. Background technique [0002] At present, the production and processing of aluminum fan blades for motors is made of forged aluminum material, the shape is extremely special, the installation part is relatively large, and the blade body part is relatively small. Aluminum fan blades used to be forged into billets by using aluminum rods, which wastes a lot of materials. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a production process of aluminum fan blades for motors. The method design is reasonable and ingenious, saves materials, is economical and practical, has high product precision, and improves production efficiency. [0004] In order to achieve the above-mentioned purpose of the invention, the present invention proposes the following technical solutions: ...
