Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum panel processing technology for curtain walls, specifically a forming equipment for processing aluminum panels for curtain walls. Background Technology
[0002] Aluminum panels for curtain walls are commonly used in building exterior decoration. Their main characteristics are waterproofness, corrosion resistance, and good weather resistance. During the production process, due to the construction drawings, some aluminum panels may need to be shaped, such as bending them into arcs or bending them into multiple right angles to improve aesthetics or facilitate installation. For example, bending the four sides of the aluminum panel into right angles makes it easier to drill holes for screw fixing. Or bending the aluminum panel into arcs or right angles makes the entire curtain wall shape more three-dimensional and beautiful. In these cases, stamping dies are needed to stamp the aluminum panels into shape.
[0003] An adjustable lower die device for bending irregularly shaped plates, application number 202321700606.7, includes a die base with a slot inside. On both sides of the slot are a set of adjustment plates (I), and on opposite sides of each of the two sets of adjustment plates (I) are connected non-marking inserts. The non-marking inserts have threaded through holes. Pads are fixedly installed on both sides of the die base, and on each of the pads are a set of adjustment plates (II). Both sides of the die base have through holes, and connecting screws are also connected to the die base. The connecting screws pass sequentially through the corresponding set of adjustment plates (II), the through holes, and the adjustment plates (I), and are threadedly connected to the non-marking inserts through the threaded through holes. This invention, through the design of adjustment plates (I and II), allows adjustment of the lower die opening and the spacing between the two non-marking inserts, enabling bending of workpieces of different thicknesses. The non-marking insert design avoids interference with irregularly shaped bending parts, resulting in higher versatility, ease of use, and low cost.
[0004] Most existing molds use similar technical solutions for adjusting the opening, which achieve the adjustment effect by adjusting the number of shims. However, the large number of shims makes it time-consuming and labor-intensive to remove and place them, and they also need to be tightened with bolts. This makes the operation of adjusting the mold opening by removing and installing shims cumbersome and labor-intensive. Utility Model Content
[0005] Therefore, the purpose of this utility model is to provide a forming equipment for processing aluminum panels for curtain walls, so as to solve the technical problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a forming device for processing aluminum panels for curtain walls, comprising a lower mold base, on one side of which are installed two servo motors and two worm gear reducers, and the output ends of the two worm gear reducers are connected to bidirectional lead screws. The tops of the two bidirectional lead screws are connected to two support seats, and the bottoms of the two support seats are each equipped with an electromagnet. The two support seats are respectively connected to two templates and two baffles on their sides. One of the support seats is connected to a laser rangefinder on its outer surface, back, and bottom, and the other support seat is connected to a reflector on its outer surface, back, and bottom. Four scales are respectively connected to the top two sides of the lower mold base.
[0007] By adopting the above technical solution, after the two servo motors are started, their output ends drive two bidirectional lead screws to rotate through two worm gear reducers. At this time, both sides of the two support seats are simultaneously subjected to force and begin to displace, thus facilitating the automatic adjustment of the mold opening size. During this process, the distance between the two sides and the middle of the two support seats can be measured by three laser rangefinders and reflectors, respectively. When the support seats shift due to errors, a single servo motor can be activated. The output end of the servo motor is decelerated through a worm gear reducer to improve the adjustment accuracy. Afterward, the corresponding bidirectional lead screw rotates independently, causing one side of the support seat to be slightly displaced by force, making it easier to adjust the two support seats to a level position. In operation, if the laser rangefinder is damaged, staff can manually adjust the servo motor by visually switching it on and off using a ruler. The presence of a stop prevents tools from falling into or aluminum plates from being placed in the gap between the support base and the lower mold base. After adjustment, the electromagnet is activated to firmly hold the support base onto the lower mold base, increasing the resistance to support base displacement. The worm gear reducer has a self-locking property, and the aluminum plate has low hardness; as a curtain wall, its thickness is not very large, so the force exerted on the template and support base during bending is not very large. Due to the combination of these factors, the phenomenon of support base displacement affecting bending accuracy during bending is effectively avoided.
[0008] Furthermore, the support base is slidably connected to the lower mold base, and the support base is threadedly connected to a bidirectional lead screw.
[0009] By adopting the above technical solution, when it is necessary to bend curtain wall aluminum plate blanks of other thicknesses or other alloy types, the staff turns on the servo motor. After the two servo motors start, the output ends drive the two bidirectional lead screws to rotate through the two worm gear reducers respectively. At this time, the two sides of the two support seats are simultaneously subjected to force and begin to displace, which facilitates automatic adjustment of the mold opening size.
[0010] Furthermore, the template is made of hard alloy steel and the surface of the template is polished.
[0011] By adopting the above technical solution, the high hardness and smooth surface of the template effectively reduce the occurrence of creases, improve the aesthetics after bending, and reduce the impact on the appearance and quality of the curtain wall aluminum panel.
[0012] Furthermore, the top side of the template is provided with rounded corners, and the two templates are mirror images of each other.
[0013] By adopting the above technical solution, and by setting rounded corners on the bent contact surface, the contact pressure between the filter plate and the template is reduced, thereby reducing the generation of indentations.
[0014] Furthermore, the cross-section of the baffle is in the shape of a "7", and the two baffles are set in a mirror image.
[0015] By adopting the above technical solution, the presence of the baffle prevents tools from falling into or aluminum plates from being placed in the gap between the support base and the lower mold base, thus facilitating use.
[0016] Furthermore, the three laser rangefinders correspond to the three reflective blocks respectively.
[0017] By adopting the above technical solution, the distance between the two sides and the middle of the two support seats is measured by three laser rangefinders and reflectors respectively. When the support seats are offset due to errors, a servo motor can be turned on individually. The output of the servo motor is reduced in speed by a worm gear reducer to improve the adjustment accuracy.
[0018] Furthermore, a control cabinet is installed on one side of the outer surface of the lower mold base, and the servo motor, laser rangefinder and electromagnet are all electrically connected to the control cabinet.
[0019] By adopting the above technical solution, three laser rangefinders and a reflector block are used to measure the distance between the two sides and the middle of the two support bases respectively. The three laser rangefinders convert the measured distance information into signals, and then output analog signals or digital pulse signals to the control cabinet. After receiving the signals, the control cabinet processes and calculates the information, compares the set value with the feedback value, and compares the differences between the three laser rangefinders. When the support base shifts due to error, the control cabinet outputs analog voltage or analog current signals to control the speed or torque of the servo motor, thereby activating a specific servo motor.
[0020] Furthermore, the template is connected to the support base by a plurality of first bolts, and a plurality of nuts are fixed to the lower side of one side of the support base. The template is detached and connected to the support base by the first bolts.
[0021] By adopting the above technical solution, when the template is severely worn, the staff can remove the first bolt with an Allen wrench to stop the template from being restricted. At this time, the staff can replace the template. After the template is placed, the staff only needs to screw the first bolt in. The first bolt will cooperate with the nut fixed on the side of the support to tighten and restrict the template, preventing the template from loosening and falling off.
[0022] Furthermore, the laser rangefinder and the reflector are both connected to the support base by a second bolt, and the support base has threaded holes on its outer surface, back, and bottom. The laser rangefinder and the reflector are detachably connected to the support base by the second bolt.
[0023] By adopting the above technical solution, when the laser rangefinder or reflector is damaged, the staff can remove the second bolt with an Allen wrench to stop the laser rangefinder or reflector from being restricted. At this time, the staff can replace the laser rangefinder or reflector. After the replacement is completed, the staff only needs to screw in the second bolt. The second bolt will cooperate with the threaded hole on the outer surface, back or bottom of the support to complete the fastening work.
[0024] In summary, the present invention has the following main advantages:
[0025] 1. This utility model utilizes a servo motor, bidirectional lead screw, laser rangefinder, and reflector. After the two servo motors are started, their outputs drive the two bidirectional lead screws to rotate via two worm gear reducers. Simultaneously, both sides of the two support seats are subjected to force and begin to displace, facilitating automatic adjustment of the mold opening size. During this process, the distance between the two sides and the middle of the two support seats can be measured using three laser rangefinders and the reflector. If the support seats shift due to error, a single servo motor can be activated. The servo motor's output is reduced in speed by a worm gear reducer to improve adjustment accuracy. The corresponding bidirectional lead screw then rotates independently, causing a slight displacement on one side of the support seat, facilitating the adjustment of the two support seats to a parallel state. If the laser rangefinder is damaged, the operator can also manually switch the servo motors on and off using a ruler and visual inspection. Furthermore, the presence of a stop prevents tools from falling into or aluminum plates from being placed in the gap between the support seat and the lower mold seat. This facilitates electric adjustment and effectively reduces the time and effort required to adjust the mold opening size.
[0026] 2. This utility model, through the setting of a worm gear reducer and an electromagnet, after adjustment, activates the electromagnet to firmly attach the support seat to the lower mold base, increasing the resistance to support seat displacement. Furthermore, the worm gear reducer has a self-locking property, and the aluminum plate has low hardness, and its thickness as a curtain wall is not very large, so the force applied to the template and support seat during bending is not very large. Due to the combination of these factors, the phenomenon of support seat displacement affecting bending accuracy during bending is effectively avoided; it also facilitates limiting and prevents support seat displacement during bending forming.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0034] The embodiments of this utility model will be described below based on its overall structure.
[0035] Example 1:
[0036] A forming device for processing aluminum panels for curtain walls, such as Figures 1-5As shown, the assembly includes a lower mold base 1. Two servo motors 2 and two worm gear reducers 3 are mounted on one side of the lower mold base 1. The output ends of both worm gear reducers 3 are connected to bidirectional lead screws 4. Two support seats 5 are connected to the top of the two bidirectional lead screws 4. The support seats 5 are slidably connected to the lower mold base 1 and threadedly connected to the bidirectional lead screws 4. Electromagnets 11 are mounted on the bottom of both support seats 5. Two templates 6 and two retainers 7 are connected to the sides of the two support seats 5 respectively. The templates 6 are made of hard alloy steel and have a polished surface. A circular... At the corner, two templates 6 are mirrored, and the cross-section of the support frame 7 is "7" shaped. Two support frames 7 are mirrored. One support base 5 has laser rangefinders 8 connected to its outer surface, back, and bottom. The other support base 5 has reflective blocks 9 connected to its outer surface, back, and bottom. Three laser rangefinders 8 correspond to three reflective blocks 9. Four scales 10 are connected to the top two sides of the lower mold base 1. After the two servo motors 2 start, their output ends drive two bidirectional lead screws 4 to rotate through two worm gear reducers 3. At this time, both sides of the two support bases 5 are simultaneously subjected to force and begin to displace, thus… To facilitate automatic adjustment of the mold opening size, three laser rangefinders 8 and reflector blocks 9 can be used to measure the distance between the two sides and the middle of the two support seats 5 respectively. When the support seats 5 shift due to errors, a single servo motor 2 can be activated. The output of the servo motor 2 is reduced in speed through a worm gear reducer 3 to improve the adjustment accuracy. Then, the corresponding bidirectional lead screw 4 rotates independently, causing a slight displacement on one side of the support seat 5, making it easy to adjust the two support seats 5 to a parallel state. If the laser rangefinder 8 is damaged, the operator can also manually adjust it by visual inspection using a ruler 10. The servo motor 2 is adjusted by switching on the switch; and the presence of the stop 7 prevents tools from falling into or aluminum plates from being placed in the gap between the support base 5 and the lower mold base 1; after adjustment, the electromagnet 11 is turned on to firmly attract the support base 5 onto the lower mold base 1, increasing the resistance to the displacement of the support base 5. In addition, the worm gear reducer 3 has a self-locking property, and the aluminum plate has low hardness and its thickness is not very large when used as a curtain wall, so the force applied to the template 6 and the support base 5 when bending is not very large. Due to the combination of these factors, the phenomenon of displacement of the support base 5 during bending, which affects the bending accuracy, is effectively avoided.
[0037] See Figure 1 and Figure 2In the above embodiment, a control cabinet 14 is installed on one side of the outer surface of the lower mold base 1. The servo motor 2, laser rangefinder 8, and electromagnet 11 are all electrically connected to the control cabinet 14. The distance between the two sides and the middle of the two support bases 5 is measured by the three laser rangefinders 8 and the reflector block 9 respectively. The three laser rangefinders 8 convert the measured distance information into signals. Then, the three laser rangefinders 8 output analog signals or digital pulse signals to the control cabinet 14. After receiving the signals, the control cabinet 14 processes and calculates the information, compares the set value with the feedback value, and compares the difference between the three laser rangefinders 8. When the support base 5 is offset due to error, the control cabinet 14 outputs analog voltage or analog current signals to control the speed or torque of the servo motor 2, thereby turning on a certain servo motor 2 individually.
[0038] Example 2:
[0039] Based on the above embodiment one, the following settings are made to facilitate structural replacement.
[0040] See Figures 1-4 In the above embodiment, multiple first bolts 12 connect the template 6 and the support base 5. Multiple nuts are fixed to the lower side of one side of the support base 5. The template 6 is detached from the support base 5 via the first bolts 12. When the template 6 is severely worn, the worker removes the first bolts 12 using an Allen wrench, thus ending the limitation on the template 6. At this time, the worker can replace the template 6. After placing the template 6, the worker only needs to screw in the first bolts 12. The first bolts 12 will cooperate with the nuts fixed to the side of the support base 5 to tighten and limit the template 6, preventing the template 6 from loosening and falling off; the laser rangefinder 8 and the reflector block 9 are connected with... Each support base 5 is connected by a second bolt 13. Threaded holes are provided on the outer surface, back, and bottom of the support base 5. The laser rangefinder 8 and the reflector block 9 are detachably connected to the support base 5 via the second bolt 13. When the laser rangefinder 8 or the reflector block 9 is damaged, the operator can remove the second bolt 13 with an Allen wrench, thereby ending the limitation on the laser rangefinder 8 or the reflector block 9. At this time, the operator can replace the laser rangefinder 8 or the reflector block 9. After replacement, the operator only needs to screw in the second bolt 13. The second bolt 13 will cooperate with the threaded holes on the outer surface, back, or bottom of the support base 5 to complete the fastening work.
[0041] The implementation principle of this utility model is as follows: First, the worker places the blank of the curtain wall aluminum panel on the top of the baffle 7. The presence of the baffle 7 prevents tools from falling in or the aluminum panel from being placed in the gap between the support seat 5 and the lower mold seat 1. After adjusting the bending position, the worker opens the stamping and bending device. The hydraulic structure drives the upper mold to move down and apply force to cooperate with the template 6 to bend the blank of the curtain wall aluminum panel to a specified angle, the specific angle of which is controlled by the worker. During the stamping process, the electromagnet 11 is activated so that the support seat 5 is firmly attracted to the lower mold seat 1, increasing the resistance to the displacement of the support seat 5. In addition, the worm gear reducer 3 has a self-locking property. The aluminum panel has low hardness and its thickness is not very large when used as a curtain wall, so the force applied to the template 6 and the support seat 5 during bending is not very large. Due to the combination of these factors, the phenomenon of displacement of the support seat 5 during bending, which affects the bending accuracy, is effectively avoided. Furthermore, because the template 6 has high hardness, a smooth surface, and rounded corners, the occurrence of creases is effectively reduced, improving the aesthetics after bending and reducing the impact on the appearance and quality of the curtain wall aluminum panel.
[0042] Different building curtain walls are designed for different scenarios. In some areas, the wind is strong, or the seaside is alkaline. Therefore, the specific grade and thickness of the aluminum panels used for the curtain wall will be changed accordingly. Rare metals and thickness parameters may be added to achieve better structural strength, weather resistance, and corrosion resistance. To optimize bending force and control precision, it is usually necessary to adjust the opening size of the mold. When bending aluminum panel blanks of other thicknesses or alloy types are required, the operator turns on the servo motor 2. After the two servo motors 2 are started, their output ends drive the two bidirectional lead screws 4 to rotate through the two worm gear reducers 3. At this time, the two sides of the two support seats 5 are simultaneously subjected to force and begin to displace, which facilitates the automatic adjustment of the mold opening size.
[0043] During this process, the distance between the two sides and the middle of the two support seats 5 can be measured by three laser rangefinders 8 and reflector blocks 9 respectively. The three laser rangefinders 8 convert the measured distance information into signals, and then output analog signals or digital pulse signals to the control cabinet 14. After receiving the signals, the control cabinet 14 processes and calculates the information, compares the set value with the feedback value, and compares the difference between the three laser rangefinders 8. When the support seat 5 is offset due to error, the control cabinet 14 outputs analog voltage or analog current signals to control the speed or torque of the servo motor 2, thereby turning on a certain servo motor 2 individually. The output end of the servo motor 2 is decelerated through the worm gear reducer 3 to improve the adjustment accuracy. Then the corresponding bidirectional lead screw 4 rotates individually, so that one side of the support seat 5 is slightly displaced by force, which makes it easy to adjust the two support seats 5 to a parallel state. If the laser rangefinder 8 is damaged, the staff can also manually switch the servo motor 2 on and off by visual means using the scale 10.
