Description

Technical Field

[0001] The present invention relates to the field of industrial ceiling fan blade processing, and specifically to an industrial ceiling fan and its manufacturing method. Background Art

[0002] An industrial ceiling fan is a fan specifically designed for large spaces, mainly used to improve air circulation and temperature control. Such fans are usually used in factories, warehouses, commercial premises and other large spaces to maintain a comfortable environment and work efficiency. Industrial ceiling fans are generally larger than household ceiling fans, and the blade diameter can reach 2 meters or more; they are usually equipped with high-performance motors that can generate strong airflows at low rotational speeds. Many industrial ceiling fans are made of sturdy materials and can withstand harsh working environments. Compared with traditional air conditioners, industrial ceiling fans have lower energy consumption and are suitable for long-term use.

[0003] The structure of the industrial ceiling fan blade determines the strength of the fan's heat dissipation. Many existing industrial ceiling fans are either made of aluminum by one-piece molding or formed by rolling thick cold pressing plates. The fan blades formed by these two methods are not only relatively heavy, but also reduce the heat dissipation efficiency of the entire fan and increase industrial electricity consumption.

[0015] In an embodiment, the fan blade of the industrial ceiling fan produced by the corresponding method and processing equipment divides the fan blade of the industrial ceiling fan into a first chamber structure 1 and a second chamber structure 2, and the entire interior of the fan blade of the industrial ceiling fan is "divided into two" (into the first chamber structure 1 and the second chamber structure 2) by the reinforcing rib plate 3 integrally formed with the first chamber structure 1 and the second chamber structure 2. At the same time, due to the different bending and inclination directions and positions of the reinforcing rib plate 3, the produced fan blade of the industrial ceiling fan can be applied to different environments (such as the force on the industrial ceiling fan, the magnitude of the wind force, etc.).

[0016] Embodiment 2 As Figure 2 shown, further, in order to manufacture the fan blade of the industrial ceiling fan, the method for manufacturing this type of fan blade of the industrial ceiling fan is as follows: First, perform fan blade punching: First, punch the fan blade plate according to the design requirements and positions. During the implementation process, the fan blade plate is extruded into shape by using a mold and a forming roller at one end that can be movably adjusted, and then the fan blade plate is punched by a milling machine.

[0017] Subsequently, preform the fan blade: Pass the fan blade plate to be processed through the flattening mechanism of the forming processing equipment to flatten the fan blade plate, and then bend the flattened fan blade plate into the designed preliminary shape structure by the forming processing equipment.

[0018] In an embodiment, the flattening mechanism provided includes a first flattening roller and a second flattening roller which are rotatably arranged and relatively movable (not marked in the attached drawings). A first rotating shaft is passed through the first flattening roller. Two ends of the first rotating shaft are respectively rotatably connected to a first movable frame through bearings, and one end of the first rotating shaft is connected to the output end of a first servo motor. The housing of the first servo motor is mounted and connected to the first movable frame through a motor bracket.

The cylinder body of the first air cylinder is fixed to the frame on one side of the inlet of the molding and processing equipment through bolts; a second rotating shaft is passed through the second flattening roller. Two ends of the second rotating shaft are respectively rotatably connected to a second movable frame through bearings. The second movable frame is arranged on the side of the inlet of the molding and processing equipment away from the first movable frame, and the bottom end of the second movable frame is slidably mounted and connected to the frame on the side of the inlet of the molding and processing equipment away from the first movable frame through a sliding guide rail; one end of the second rotating shaft is connected to the output end of a second servo motor.

A second air cylinder for pushing the second movable frame to move is mounted and connected to the second movable frame. The cylinder body of the second air cylinder is fixed to the frame on the side of the inlet of the molding and processing equipment away from the first movable frame through bolts.

[0019] When processing the fan blade plate to be processed through a molding and processing equipment (existing fan blade molding and processing equipment), in order to flatten the fan blade plate to be processed and thus ensure the appearance and structural quality of the processed fan blade, a flattening mechanism, namely the "flattening mechanism" described above, is installed at the inlet of the molding and processing equipment; when the fan blade plate to be processed passes through the flattening mechanism, the relative position between the first flattening roller and the second flattening roller of the flattening mechanism is adjusted in real time according to the thickness, length, etc. of the fan blade plate to be processed actually, so as to flatten the fan blade plate.

[0020] Embodiment 3 On the basis of Embodiment 2, that is, after pre-forming the fan blade processing, the fan blade is processed and welded into shape: The preliminarily formed fan blade is processed through the molding and processing equipment to bend the reinforcing rib plate 3, and then the fan blade is separated into a first chamber structure 1 and a second chamber structure 2 by the bent reinforcing rib plate 3 through the molding and processing equipment; then the end of the fan blade plate is preliminarily welded to the bent reinforcing rib plate 3 by a welding equipment.

[0021] In this embodiment, when the forming and processing equipment separates the fan blade into the first chamber structure 1 and the second chamber structure 2 through the bent reinforcing rib plate 3, one side of the flattened fan blade plate is bent into the first chamber structure 1 through the forming roller of the forming and processing equipment. Among them, the upper arc plate of the first chamber of the first chamber structure 1 and the lower surface plate of the first chamber are bent into the form of a windward fold angle through the forming roller, and the upper arc plate of the first chamber and the lower surface plate of the first chamber are integrally bent and formed through the windward fold angle. At the same time, the other side of the flattened fan blade plate is also bent into the second chamber structure 2 through the forming roller of the forming and processing equipment. Among them, the upper arc plate of the second chamber of the second chamber structure 2 and the lower surface plate of the second chamber are bent into the form of a diversion fold angle through the forming roller, and the upper arc plate of the second chamber and the lower surface plate of the second chamber are integrally bent and formed through the diversion fold angle. In addition, during the process of the forming and processing equipment bending and processing the reinforcing rib plate 3, according to the design requirements, the reinforcing rib plate 3 with different inclined forms is bent, and the end of the reinforcing rib plate 3 is also bent with a bent end that is adapted to contact the streamline structure of the first chamber structure 1 or the second chamber structure 2, so as to support and stabilize the formed fan blade.

[0022] Further, in the specific implementation, when the flattened fan blade plate is passed through the forming and processing equipment to form the preliminary shape structure of the required fan blade. During the preliminary forming process, the reinforcing rib plate 3 is bent into different inclined direction positions according to the needs; the attached drawing is only one of the bending methods, that is, the reinforcing rib plate 3 is integrally formed with the upper arc plate of the first chamber of the first chamber structure 1, and the other end of the reinforcing rib plate 3 is inclined towards one end of the second chamber structure 2, and it can also be bent into: a. The reinforcing rib plate 3 is integrally formed with the upper arc plate of the first chamber of the first chamber structure 1, and the other end of the reinforcing rib plate 3 is inclined away from one end of the second chamber structure 2; b. The reinforcing rib plate 3 is integrally formed with the lower surface plate of the first chamber of the first chamber structure 1, and the other end of the reinforcing rib plate 3 is inclined towards one end of the second chamber structure 2; c. The reinforcing rib plate 3 is integrally formed with the lower surface plate of the first chamber of the first chamber structure 1, and the other end of the reinforcing rib plate 3 is inclined away from one end of the second chamber structure 2; d. The reinforcing rib plate 3 is integrally formed with the upper arc plate of the second chamber of the second chamber structure 2, and the other end of the reinforcing rib plate 3 is inclined towards one end of the first chamber structure 1; c. The reinforcing rib plate 3 is integrally formed with the upper arc plate of the second chamber of the second chamber structure 2, and the other end of the reinforcing rib plate 3 is inclined away from one end of the first chamber structure 2; e. The reinforcing rib plate 3 is integrally formed with the lower surface plate of the second chamber of the second chamber structure 2, and the other end of the reinforcing rib plate 3 is inclined towards one end of the first chamber structure 1; f. The reinforcing rib plate 3 is integrally formed with the lower surface plate of the second chamber structure 2 of the second chamber structure, and the other end of the reinforcing rib plate 3 is inclined away from one end of the first chamber structure 1; The above are only some implementation structural examples of integral processing and forming, and there are other implementation examples, which are not listed exhaustively one by one.

[0023] By integrally forming the reinforcing rib plate 3 with the entire processed fan blade plate and bending it, although the operation steps are much more complicated and troublesome, it can ensure the overall quality, reduce the welding seams and welding time, and can form the required fan blade structure type by integral bending according to needs. While ensuring the quality, it is also applicable to different environmental requirements, achieving multiple benefits at once.

[0024] After bending the reinforcing rib plate 3, then the first chamber structure 1 and the second chamber structure 2 are further relatively pressed and brought closer together by a forming processing device, so that the other end of the fan blade plate abuts against the reinforcing rib plate 3, and the bent fan blade is welded by a welding device. Specifically, the end of the welded fan blade plate abuts against the position of the reinforcing rib plate 3. It should be noted here that the welding device uses a laser welding gun, and the laser welding gun is installed and connected to a robot arm with full automatic control. In this way, by controlling the automatic robot arm to drive the laser welding gun, the position where the end of the fan blade plate abuts against the reinforcing rib plate 3 is welded all at once, reducing the welding seams and ensuring the overall quality.

[0025] Embodiment 4 Further, after welding the fan blade, then the structure of the fan blade is qualitatively processed: the welded fan blade is cut into the required fan blade length by a cutting machine; then the fan blade is processed, polished and buffed: the formed fan blade after cutting is polished and buffed by a polishing and buffing device for the welded part, the end and the corner parts of the formed fan blade to remove burrs and the like.

[0026] In the embodiment, the cutting machine is installed and connected to a robot arm, and by controlling the robot arm to drive the cutting machine to move freely, the fan blade is cut into the required shape structure.

[0027] Since there are many burrs and the like on the fan blade after cutting, it is necessary to polish and buff the fan blade. The polishing and buffing device used for polishing and buffing the fan blade includes a buffing mechanism; the buffing mechanism includes several pairs of buffing roller groups, and each buffing roller group includes an upper buffing roller and a lower buffing roller; the upper buffing roller is rotatably installed and connected to an upper sliding support through a rotating shaft, and the upper sliding support is movably installed and connected to the frame of the polishing and buffing device through an electric guide rail; the lower buffing roller is rotatably installed and connected to a lower sliding support through a rotating shaft, the lower sliding support is arranged to be relatively movable with the upper sliding support, and the lower sliding support is movably installed and connected to the side of the frame of the polishing and buffing device far from the upper sliding support through an electric guide rail.

[0028] The industrial fan blades produced by this method can not only ensure the quality of the produced fan blades and reduce the overall weight of the ceiling fans in production and processing, but also, through this method, quickly produce the fan blades of the industrial ceiling fans with guaranteed quality and quantity, saving costs while improving the production and processing efficiency, and having higher economic benefits.
