Description

Technical Field

[0001] This utility model belongs to the field of fan manufacturing, and relates to fan blade manufacturing equipment, and in particular to an aluminum fan blade pressing production line. Background Technology

[0002] The fan blade is the rotating part of a fan. Multiple inclined surfaces are set on the fan blade. When it rotates, the inclined surfaces on the fan blade guide the airflow and push the airflow to one side to fan the air.

[0003] For small fans with lower power, the blades need to be lighter to improve energy efficiency. Using aluminum sheets to manufacture fan blades is a good option. Aluminum sheets have a smooth surface and high plasticity, allowing for direct pressing to form the blades with relatively low pressure. Traditional blade pressing equipment typically requires manual loading and unloading, as well as manual operation of the pressing equipment. For example, the one-time pressing method for steel blades disclosed in Chinese patent CN103480705A uses pressing equipment to press the steel blades. Temperature control is required during pressing to prevent the steel from springing back, making the process very complex. Furthermore, the equipment used in this method lacks continuity, and the steel sheets require intermediate heating. Therefore, it still relies heavily on manual operation, resulting in low production efficiency and high labor intensity. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing fan blades requiring manual operation, resulting in low production efficiency and high labor intensity. It provides an aluminum fan blade pressing production line that adopts an automated feeding, calibration, pressing, and discharging production line design, realizing one-time feeding and automatic processing of aluminum fan blades. Moreover, using aluminum fan blades, they can be pressed into shape in one go, resulting in high production efficiency and good product consistency.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: an aluminum fan blade pressing production line, including a frame, the frame including a feeding turntable, one or more stacking racks are arranged around the feeding turntable, the stacking racks are stacked with aluminum sheets to be pressed, a feeding station is arranged on one side of the feeding turntable, the feeding turntable rotates to make the stacking racks enter the feeding station, a lifting bracket is arranged at the feeding station; a calibration station is arranged behind the feeding station, a pressing station is arranged behind the calibration station, and a discharge conveyor belt is arranged behind the pressing station; the frame is also provided with a lifting and translating feeding arm, the feeding arm is provided with a first suction cup from front to back to convey the aluminum sheets to be pressed from the feeding station to the calibration station, a second suction cup from the calibration station to the pressing station to convey the aluminum sheets to be pressed, and a third suction cup from the pressing station to the discharge conveyor belt to convey the aluminum fan blades.

[0006] This device features multiple stacking racks on the feeding turntable. When one rack rotates to the feeding station, the others do not affect the feeding process. When all racks are full, it can operate automatically for extended periods. The feeding station utilizes a lifting bracket to support the stacked aluminum sheets from the bottom, gradually raising it to maintain a relatively stable position where the first suction cup holds the aluminum sheets. The first suction cup delivers the aluminum sheets from the feeding station to the calibration station, and the second suction cup delivers them to the pressing station. The pressing station uses traditional upper and lower pressing molds to press the aluminum sheets into aluminum fan blades. The aluminum sheets are highly malleable and can be pressed in one step. After pressing, the aluminum fan blades are gripped and conveyed to the discharge conveyor belt by a third suction cup. After a certain number of blades are stacked, they are transported to the rear for packaging. This device achieves a high degree of automation in aluminum fan blade pressing and can operate stably and fully automatically for extended periods, significantly reducing labor costs and enabling standardized production of aluminum fan blade products.

[0010] Preferably, the calibration station includes a positioning block, a first calibration cylinder, and a second calibration cylinder. The positioning block, the first calibration cylinder, and the second calibration cylinder are arranged in a triangle around the aluminum sheet to be pressed at the calibration station. The calibration station utilizes a three-point calibration method, whereby the two calibration cylinders push the sides of the aluminum sheet to be pressed from two different angles, causing the gap between two blades of the aluminum sheet to rest against the positioning block, thus achieving calibration positioning.

[0011] Preferably, the positioning block, the first calibration cylinder, and the second calibration cylinder are spaced 120 degrees apart around the circumference of the aluminum sheet to be pressed.

[0012] Preferably, the aluminum fan blade has a flat surface in the middle, with multiple arc-shaped fan blades arranged around the center.
