Description

Technical Field

[0001] This invention relates to the field of electromechanical system component processing, and in particular to a device and method for manufacturing air duct guide vanes. Background Technology

[0002] In a duct system, when airflow passes through parts with variable cross-sections, elbows, or tees, the internal airflow organization will change significantly. In order to reduce the energy loss of airflow, reduce system noise, and ensure uniform airflow velocity within the cross-section, guide vanes are usually used in the above-mentioned components.

[0003] Currently, there is a lack of automated processing equipment and operating systems for the guide vanes in air ducts. As a result, when processing components such as elbows on the construction site or in the factory, different models of guide vanes are formed by manually cutting and folding the sheet metal and then hammering it at a certain angle. This operating method has the following drawbacks.

[0004] 1. The low level of mechanization and complete reliance on manual labor leads to increased labor costs. Furthermore, the high labor intensity and cost during cutting and hammering processes result in significant costs.

[0005] 2. The manufacturing quality of the guide vanes is entirely dependent on the operator's experience. Furthermore, for guide vanes with different curvatures, excessive deviations during manufacturing can lead to improper installation or poor flow guidance, directly affecting construction efficiency and usage effectiveness.

[0006] 3. The noise from hammering and cutting on-site or in the factory is high. Due to various uncontrollable factors caused by human operation, the amount of rework is large. At the same time, the operation has a high risk factor and serious waste of materials, which does not meet the requirements of ecological benefits. Summary of the Invention

Detailed Implementation

[0048] To illustrate the technical solutions of the invention in more detail, specific embodiments are listed below to demonstrate the technical effects; it should be emphasized that these embodiments are used to illustrate the invention and are not intended to limit the scope of the invention.

[0049] The duct guide vane manufacturing device provided by this invention, such as Figures 1 to 10 As shown, it includes a sheet metal cutting mechanism 100, a stamping mechanism 200, and a bending mechanism 300. The sheet metal cutting mechanism 100 is used to cut the sheet metal to be cut into the corresponding shape (approximately a rectangle, with one set of corresponding sides being serrated, i.e., the two sides of the rectangle are serrated). The stamping mechanism 200 is used to stamp out the curvature of the guide vane. The bending mechanism 300 is used to make the folded edges on both sides of the guide vane that connect with the air duct system.

[0050] Specifically, please refer to the following: Figures 1 to 3 The sheet metal cutting mechanism 100 includes a base 110, a moving module 120, and a laser cutting module 130. The moving module 120 is fixed to the base 110, and the laser cutting module 130 is fixed to the moving module 120. The laser cutting module 130 includes a cutting head 131. The sheet metal to be cut (not shown) (in this application, the sheet metal to be cut can be waste material from the cutting of air ducts, increasing the utilization rate of waste materials, realizing low-carbon green construction, and compared with manual cutting, it does not require the use of scribing cutting, and achieves more precise cutting) is placed on the base 110 below the cutting head 131. The moving module 120 moves the cutting head 131 above the sheet metal to be cut and cuts the sheet metal according to the required shape and size.

[0051] Please refer to this carefully. Figure 1 and combined Figure 5 and Figure 6The stamping mechanism 200 includes a hydraulic module 210, a stamping plate 220, a heating module 230, an arc-shaped die 240, a stamping platform 250, and a concave tray 260. The stamping plate 220 is fixedly installed at the output end of the hydraulic module 210. The heating module 230 is installed on the stamping plate 220, and the arc-shaped die 240 is installed below the stamping plate 220. The concave tray 260 is installed on the stamping platform 250, and the shape and position of the concave tray 260 correspond to the arc-shaped die 240. The semi-finished product (not shown) processed by the sheet metal cutting mechanism 100 is placed on the concave tray 260. The hydraulic module 210 drives the arc-shaped die 240 to press downwards, fitting it against the concave tray 260. At the same time, the heating module 230 heats the semi-finished product, forming the curved arc of the guide vane.

[0052] Please refer to this carefully. Figures 7 to 9 The bending mechanism 300 includes an I-shaped slider 310, a base 320, a gate arm 330, and a gate plate 340 connected in sequence. Parallel grooves 251 are provided on both sides of the concave tray 260. The I-shaped slider 310 is confined within the grooves 251 and can slide along them. The position and direction of the gate plate 340 correspond to the folded edges of the guide vane. The concave tray 260 supports the guide vane, and the gate plate 340 presses against the edges of the guide vane, forming the folded edges on both sides of the guide vane.

[0053] This invention increases the automation level of duct guide vane manufacturing, reduces the intensity of manual operation, saves labor costs, and greatly improves manufacturing efficiency. It has a wide range of applications and can meet the processing needs of guide vanes of various sizes and curvatures. The manufacturing process is quieter, thus having less impact on the surrounding environment. The quality of guide vanes of different models is significantly improved, and the guide vanes in the same batch have high consistency and uniform curvature, which not only increases the success rate of subsequent installation but also promotes the efficient and energy-saving operation of the duct system.

[0054] In some embodiments, please refer to the following: Figure 2 and Figure 3The moving module 120 includes an X-axis motor 121, an X-axis guide rail 122, an X-axis slider 123, a Y-axis motor 124, a Y-axis guide rail 125, and a Y-axis slider 126. The X-axis guide rail 122 consists of two parallel lines. The X-axis motor 121 drives the X-axis slider 123 to slide along the X-axis guide rail 122. The two ends of the Y-axis guide rail 125 are respectively fixed to the two X-axis sliders 123. The Y-axis motor 124 drives the Y-axis slider 126 to slide along the Y-axis guide rail 125. The laser cutter module 130 is fixed below the Y-axis slider 126. Because the X-axis slider 123 (Y-axis slider 126) is restricted horizontally (Y-axis or X-axis) and vertically within the groove of the X-axis guide rail 122 (Y-axis guide rail 125), it can only move along one direction (X-axis or Y-axis) under the traction of different rotation directions of the rotating shaft. This drives the X-axis slider 123 (Y-axis slider 126) covering it to move horizontally in the X-axis or Y-axis. The X-axis slider 123 can slide within a range of 1m in the X-axis direction, and the Y-axis slider 126 can also slide within a range of 1m in the Y-axis direction. In this way, the laser cutting module 130 can move to various positions in the horizontal position according to the set programming path, so as to perform cutting at various positions along the horizontal direction.

[0055] In some embodiments, both the X-axis guide rail 122 and the Y-axis guide rail 125 can adopt a lead screw structure, which provides high control precision and strong stability.

[0056] In some embodiments, please refer to the following: Figure 4a and 4b The laser cutting module 130 also includes a lifting component. The cutting head 131 is mounted below the Y-axis slider 126 via the lifting component. Specifically, the lifting component includes a telescopic cylinder 132 and a telescopic rod 133 fixedly connected to the output end of the telescopic cylinder 132. The cutting head 131 is fixed below the telescopic rod 133. The lifting component can be adjusted within a vertical range of 0.5m to facilitate the extension and retraction of the cutting head 131 in the vertical direction. When using this equipment, the path of the cutting head 131 should be determined by programming according to the size of the guide plate and the size of the serrated edge. The cutting accuracy should not exceed 0.1mm, the repeatability should not exceed 0.02mm, the cutting speed should not be too fast, preferably between 18m / min and 24m / min; the idle speed should not be less than 40m / min; the ambient humidity should be less than 90%, preferably between 60% and 80%, and the temperature should be between 0℃ and 35℃. In addition, since the sheet material is relatively thin, laser cutting is preferred, but plasma laser cutting is not recommended for the following reasons: the cutting head wears out quickly when using plasma laser cutting for thin sheets; the sheet material may deform due to excessively high temperatures; the groove may be too wide; the perpendicularity and cutting accuracy are not as good as ordinary laser cutting; and the environmental pollution is serious.

[0057] In some embodiments, please refer to the following: Figure 1 and combined Figure 5 and Figure 6 The hydraulic module 210 includes a hydraulic top cylinder 211, a push rod 212, and a top plate 213 connected in sequence, with the stamping plate 220 fixed below the top plate 213. In some embodiments, the hydraulic top cylinder 211 can achieve hydraulic extension and retraction of not less than 0.2m in the vertical direction, facilitating the rapid application of downward pressure during stamping. In some embodiments, there are two heating modules 230, respectively located on both sides above the stamping plate 220. These modules can rapidly heat the stamping plate 220 and transfer the heat to the arc-shaped mold 240 below via heating wires inside. In some embodiments, the heating modules 230 should ensure that the arc-shaped mold 240 heats up to not less than 80°C within 10 minutes, so that the semi-finished product can be better deformed into the required shape under heating during stamping. In some embodiments, the arc-shaped mold 240 is detachably installed below the stamping plate 220 and can be customized according to the different shapes of the guide vanes to be stamped. Of course, its shape should correspond to the concave tray 260 below.

[0058] In some embodiments, the concave tray 260 can also be replaced with the required curvature and width of the guide vane to be stamped (because ducts, unless otherwise specified, are generally available in several standard sizes, and the guide vane models and sizes in the elbows that match them are also relatively uniform, so the concave tray 260 and the upper arc mold 240 do not need too many models, of course, non-standard exceptions). During stamping, the laser-cut and fully cooled semi-finished product is first taken out and fixed on a suitable concave tray 260 (the concave tray 260 and the arc mold 240 are fixed after being selected according to the guide vane model). The hydraulic module 210 located about 0.2m directly above the concave tray 260 drives the arc mold 240, which is heated to above 80°C, to quickly press the arc mold 240 onto the concave tray 260 and hold it for no less than 1 minute (the arc mold 240 can only rise after the folded edges on both sides are formed) so as to make the guide vane into a uniform arc shape.

[0059] In some embodiments, the arc-shaped mold 240 is made of carbon steel. When stamping guide plates made of stainless steel or aluminum plate, the surface of the arc-shaped mold 240 can be covered with an insulating layer (not shown) to prevent electrochemical corrosion and carburization. Of course, the insulating layer should not cause a significant reduction in the thermal conductivity of the arc-shaped mold 240. Specifically, thermally conductive silicone, thermally conductive nylon, or thermally conductive plastic can be selected.

[0060] In some embodiments, the arc mold 240 and the upper stamping plate 220, the stamping plate 220 and the upper heating module 230, and the stamping plate 220 and the top plate 213 directly above can all be connected by bolts, as long as the connection purpose can be achieved. The specific connection method is not limited here.

[0061] In some embodiments, please refer to the following: Figures 7 to 9 To bend the serrated edges on both sides of the arc-shaped guide vane at 90° so that the guide vane can form a toothed contact surface with the duct elbow during installation (facilitating the fixing of the guide vane and the elbow side), the concave tray 260 has two grooves 251 with a width of about 2cm on both sides to facilitate the installation and positioning of the I-shaped slider 310 in the bending mechanism 300. In some embodiments, in the bending mechanism 300, the I-shaped slider 310 embedded in the groove 251 can drive the base 320, the gate arm 330 and the gate plate 340 above it to move synchronously on both sides of the concave tray 260 in a relatively close or relatively separated manner. The movement path of the I-shaped slider 310 can be automatically controlled by PLC programming (including the cutting process and the stamping process can be controlled by PLC). When the I-shaped slider 310 is in operation, it slides close to the long side of the concave tray 260, leaving a gap of approximately 1mm to 1.5mm (it cannot be completely flush, otherwise the folding cannot be performed). Then, it slowly pushes upward or downward through the gate 340 to complete a 90° bend in different directions. It should be noted that the speed must be controlled during the movement; if it is too fast, it may cut off the folding edge of the guide vane. In some embodiments, the moving speed can be 1cm / s; of course, it can be slightly faster when running without contacting the guide vane. In some embodiments, the gate arm 330 can be a liftable hydraulic push rod or other types of telescopic rods to control the raising and lowering of the gate 340.

[0062] In some embodiments, please refer to Figures 7 to 9 The gate 340 has two inclined surfaces 341 on the side close to the guide plate. In some embodiments, the inclination angle of the inclined surface 341 can be 45° so that when bending, the folded edge can fit well with the inclined surface 341 under the slow lifting or lowering action of the gate 340, so as to slowly form the folded edge and ensure that the folded edge is not cut off.

[0063] In some embodiments, please refer to the following: Figure 10 The inclined surface 341 can be a circular arc surface, which allows the folded edge to bend more slowly.

[0064] Please refer to this carefully. Figure 11 and combined Figures 1 to 10 The present invention also provides a method for manufacturing a duct guide vane, which uses the duct guide vane manufacturing device described above and includes the following steps:

[0065] Step 1: Fix the plate to be cut onto the machine base 110. Before fixing, check the quality of the plate to be cut and retain sufficient plate area, that is, leave a cutting edge of at least 2mm on the plate edge.

[0066] Step 2: Import the cutting parameter information in CAD or other formats into the PLC control terminal according to the shape of the guide vane to be cut, so that the plate cutting mechanism 100 can correctly identify the cutting path.

[0067] Step 3: Adjust the laser emission power of the laser cutting machine to cut the material to be cut. After sufficient cooling, remove the material to form a semi-finished product. In some embodiments, the method for determining whether "sufficient cooling" has been achieved can be: using a temperature gun to measure the temperature and check whether the temperature is within a safe range, thereby avoiding burns to personnel when removing the material.

[0068] It is worth noting that before step three, the cutter head 131 can be run idle before cutting to observe whether the cutting path meets the requirements before resetting. The laser cutting is confirmed by the PLC, which then controls the telescopic cylinder 132 on the cutter head 131 to push the cutter head 131 downward to a distance of about 2mm from the edge of the plate. Then, after a short period of focusing laser energy, it cuts along the previously set and experimental idle path.

[0069] Step 4: Place the semi-finished product flat on the concave tray 260, and heat it with the heating module 230 so that the arc surface temperature of the arc mold 240 is not less than 80°C.

[0070] It is worth noting that the arc-shaped mold 240 and the concave tray 260 need to be selected according to the specific model and shape of different guide vanes, and then fixed to the stamping plate 220 and the stamping table 250 respectively by bolting.

[0071] Step 5: The hydraulic module 210 drives the arc mold 240 to press down and keeps the arc mold 240 and the concave tray 260 fully in contact, so that the guide plate forms a fixed arc shape and is held for a period of time (e.g., 1 minute).

[0072] Step Six: Control the I-shaped sliders 310 on both sides of the concave tray 260 to slide towards the concave tray 260, driving the gate 340 to move upward or downward, forming 90° folded edges at both ends of the guide plate. In some embodiments, the I-shaped sliders 310 can be connected to a motor (or hydraulic component), and the motor rotation (or hydraulic component push) drives the I-shaped sliders 310 to move within the slide groove 251. When the gate 340 reaches directly below or above the folded edges on both sides of the pressed guide plate (depending on the design direction of the guide plate folded edges, whether it folds upward or downward), control the gate 340 to move up and down under the drive of the vertically extendable gate rod 330, ultimately forming a 90° fold, and the folding is completed.

[0073] Step 7: After the folding is completed, the arc-shaped mold 240 slowly rises upward under the drive of the hydraulic module 210.

[0074] Step 8: Take out the completed guide vane and inspect it to see if its shape meets the requirements.

[0075] After mass production, a batch of finished air guide vanes can be randomly inspected. The inspection rate can be: no less than 10% for general air conditioning systems within the same batch; and no less than 30% for air guide vanes with acoustic requirements or used in clean environments. Inspection items may include the curvature of the air guide vane, the bending angle of the folded edges, the damage rate of the sheet material, the uniformity of the sheet material thickness, and the visual appearance. After passing inspection, the air guide vanes are registered, packaged, and stored according to standard procedures.

[0076] Application results show that using this invention can significantly reduce deformation during the fabrication of the guide vanes. Due to the use of mechanized operations, it saves approximately 80% of the labor required for fabrication. It improves the success rate of manufacturing quality acceptance by about 150%, reduces waste generation by 30%, and reduces manufacturing costs by about 60% (without using manpower, relying entirely on machinery). The fabricated guide vanes have a consistent curvature and good bending performance, increasing the success rate of on-site installation by about 30% and reducing on-site installation time by about 40%.

[0077] In summary, the duct guide vane manufacturing device and method provided by the present invention includes a sheet metal cutting mechanism 100, a stamping mechanism 200, and a bending mechanism 300.

This invention increases the automation level of duct guide vane manufacturing, reduces the intensity of manual operation, saves labor costs, and greatly improves manufacturing efficiency. It has a wide range of applications and can meet the processing needs of guide vanes of various sizes and curvatures. The manufacturing process is quieter, thus having less impact on the surrounding environment.
