Description

Technical Field

[0001] This application relates to the field of refrigerator parts manufacturing, and in particular to bending equipment. Background Technology

[0002] When manufacturing refrigerator door panels, sheet-like products, such as aluminum foil, need to be pasted at the corners for insulation and moisture protection. Since the refrigerator door panel is L-shaped, the aluminum foil needs to be folded into an L-shape to fit the shape of the door panel. Furthermore, there is a layer at the edge of the door panel; the edge of the aluminum foil needs to be folded over and tucked into this layer for secure pasting.

[0003] The existing production process is as follows: operators use folding equipment to fold the edges of aluminum foil to form a flange, and then use manual or pressure equipment to press creases in the middle of the aluminum foil to complete the pre-forming of the aluminum foil; then the pre-formed aluminum foil with creases and flanges is pasted onto the refrigerator door panel.

[0004] However, completing the above process requires operators to manually transfer the aluminum foil to various devices. Because aluminum foil is relatively soft, it is easily damaged and deformed during transfer. Furthermore, the crease pressing process can easily deform the already formed edges, reducing the accuracy of the pre-forming of the aluminum foil. Additionally, positioning is required before edge folding and crease pressing, and this double positioning reduces production efficiency and increases the possibility of inaccurate positioning, further reducing the accuracy of the pre-forming of the aluminum foil. Therefore, improvements are needed. Summary of the Invention

[0005] To improve the accuracy of sheet product preforming, this application provides bending equipment.

[0006] The bending equipment provided in this application adopts the following technical solution: A bending machine includes a frame on which an operating table for placing sheet products is mounted. A bending assembly is provided on the frame, which is capable of forming creases on the sheet products. An edge-flanging assembly is provided on the bending assembly, which is capable of forming edges on the sheet products.

[0007] By adopting the above technical solution, the aluminum foil is partially placed on the operating table and partially located within the bending assembly. The bending assembly presses a crease in the center of the aluminum foil in one operation, while simultaneously driving the flanging assembly to perform a first right-angle fold on the edge of the aluminum foil; subsequently, the flanging assembly performs a second right-angle fold to form the flange. This application enables automated bending and flanging of aluminum foil; only one positioning is required to accurately press the crease and fold at the designed position, improving the precision of aluminum foil bending and flanging. This facilitates the operator in installing the formed aluminum foil onto the refrigerator door panel, improving production accuracy and efficiency. Furthermore, the flanging assembly is located on the bending assembly, combining the crease pressing and the first folding actions, shortening the required cycle time, and further improving production efficiency.

[0008] Optionally, the bending assembly includes a bending table, a pressure plate, and a bending drive. The bending table is mounted on a frame, and the sheet product is placed on the operating table and the bending table. The bending drive is mounted on the frame, and a lifting plate is connected to the bending drive. The pressure plate is mounted on the lifting plate, and the lifting plate drives the pressure plate to move closer to or away from the bending table in a vertical direction.

[0009] Optionally, a buffer is provided between the bending table and the frame. One end of the buffer is connected to the frame and the other end is connected to the bending table. The bending table can move vertically relative to the operating table. The pressure plate can contact the bending table and drive the bending table to move.

[0010] By adopting the above technical solution, the bending table is initially flush with the top wall of the operating table, facilitating the placement of aluminum foil. The bending drive mechanism drives the lifting plate to descend, which in turn drives the pressure plate to descend until the pressure plate and bending table together clamp a portion of the aluminum foil placed on the bending table. Subsequently, the pressure plate drives the bending table to descend together, compressing the buffer component. The top wall of the bending table is now lower than the top wall of the operating table, and creases are formed at the edges of the clamped portion of the aluminum foil. The buffer component allows for relative displacement between the bending table and the operating table and cushions the descent of the pressure plate, effectively reducing the descent speed of the pressure plate and minimizing the possibility of the aluminum foil being torn.

[0011] Optionally, the flanging assembly includes a flanging plate and a flanging drive component. A guide rail is horizontally mounted on the bottom wall of the lifting plate, and a track corresponding to the guide rail is mounted on the flanging plate. The guide rail and the track slide together, and the lifting plate drives the flanging plate to move vertically. The flanging plate is located on the side of the pressure plate away from the operating table. The flanging drive component is mounted on the frame and can drive the flanging plate to move horizontally relative to the pressure plate.

[0012] Optionally, a buffer is provided between the pressure plate and the lifting plate. One end of the buffer is connected to the pressure plate, and the other end is connected to the bending drive. There is a vertical relative movement between the pressure plate and the bending drive.

[0013] By adopting the above technical solution, when the pressure plate just touches the bending table, the bottom wall of the pressure plate is flush with the bottom wall of the flanging plate. The lifting plate continues to descend, compressing both the pressure plate and the buffer on the bending table. At this point, the top wall of the bending table is lower than the top wall of the operating table, and the top wall of the flanging plate is lower than the bottom wall of the bending table, completing the crease pressing and the first flanging. The lifting plate remains stationary, and the flanging drive propels the flanging plate horizontally towards the bending table for a second fold to form the flanging. Combining the crease pressing and the first flanging actions shortens the required cycle time and improves production efficiency. Compared to using two cylinders, this equipment can reduce equipment costs. The buffer on the pressure plate allows for relative displacement between the pressure plate and the flanging plate, creating a buffer that effectively reduces the descent speed of the pressure plate and decreases the possibility of the aluminum foil being torn.

[0014] Optionally, the pressure plate is provided with a locking component, one end of which is connected to the pressure plate and the other end is movably connected to the flange plate; a movable plate is movably provided on the flange plate, and a buffer is provided between the movable plate and the lifting plate; the locking component can lock the movable plate and the flange plate together, the flange driving component can contact the movable plate, and the flange driving component drives the movable plate to move the flange plate in the horizontal direction.

[0015] By adopting the above technical solution, the locking assembly locks the movable plate and the flange plate only when the relative displacement between the pressure plate and the flange plate in the vertical direction reaches the design value, allowing the flange driving component to push the movable plate and move the flange plate. If the pressure plate and the flange plate have not reached the designated position, the flange driving component can only push the movable plate, and the flange plate remains stationary. By setting up the locking assembly, damage to the flange plate, pressure plate, and bending table is avoided, improving the safety of equipment use.

[0016] Optionally, the locking assembly includes a locking plate, a connecting rod, and a wing plate. One end of the wing plate is connected to the flange plate, and the other end extends to the movable plate. There is a gap between the wing plate and the movable plate. The locking plate is elliptically mounted on the flange plate and can be inserted between the wing plate and the movable plate, so that the movable plate is connected to the flange plate. One end of the connecting rod is connected to the pressure plate, and the other end is connected to the locking plate.

[0017] By adopting the above technical solution, when the pressure plate rises relative to the flange plate, the pressure plate drives the connecting rod and the locking plate to rise, so that the locking plate is inserted between the movable plate and the wing plate, locking the movable plate and the wing plate together. The flange drive pushes the movable plate to move, and the movable plate drives the locking plate, the wing plate and the flange plate to move.

[0018] Optionally, a first slide rail is horizontally mounted on the bottom wall of the bending table, a driving component is slidably mounted on the first slide rail, and an elastic component is connected to the end of the first slide rail near the operating table. The elastic component is connected to the side wall of the driving component near the operating table. A slope column is mounted on the frame, and the driving component has an inclined surface that is in contact with the slope surface of the slope column. The slope surface of the slope column is inclined downwards towards the operating table. An adjusting component is detachably mounted on the driving component, and a material ejector plate is mounted on the adjusting component. The top wall of the material ejector plate is in contact with the bottom wall of the bending table.

[0019] By adopting the above technical solution, the operator installs the ejector plate onto the drive unit using the adjusting component and adjusts the ejector plate to a suitable position. When the bending table is flush with the operating table, the drive unit is located at the right end of the first slide rail; the bending table descends, applying a downward thrust to the drive unit, and the reaction force exerted by the slope column forces the drive unit to slide downward along the slope, causing the drive unit to slide to the left relative to the first slide rail, compressing the elastic component. The drive unit drives the adjusting component and the ejector plate to slide to the left relative to the bending table, causing the side wall of the ejector plate to move away from the side wall of the bending table. When the flanging plate is flanging, the possibility of collision between the ejector plate and the flanging plate is reduced; after the flanging is formed, the bending table rises, and the drive unit resets under the action of the elastic component, causing the adjusting component and the ejector plate to slide to the right relative to the bending table, so that the side wall of the ejector plate contacts the flanged edge of the aluminum foil and pushes the aluminum foil to detach from the bending table. By setting the ejector plate and the bending table to work together, the aluminum foil is assisted in detaching from the bending table, improving production efficiency. It can also reduce the possibility of aluminum foil being damaged when operators manually unload the material, thus improving safety.

[0020] Optionally, a groove is formed on the top wall of the operating table, and a mounting plate is installed on the inner side wall of the groove. A flip plate is movably arranged on the operating table, and the bottom wall of the flip plate can abut against the top wall of the mounting plate. A rotating seat is installed in the middle of the bottom wall of the flip plate, and a support rod is rotatably connected to the rotating seat. The end of the support rod away from the rotating seat is rotatably connected to the operating table. A rotating shaft is installed on the side wall of the flip plate near the bending table, and a second hinge is rotatably connected to the rotating shaft. A second slide rail is horizontally installed on the operating table, and the second hinge is slidably connected to the second slide rail. The second hinge is in contact with a driving member, and the driving member can drive the second hinge to move in the horizontal direction, so that the rotating shaft moves in the horizontal direction.

[0021] By adopting the above technical solution, when the driving component is located at the right end of the first slide rail, the second hinge component is also located at the right end of the second slide rail. The edge of the flip plate rests on the platform, and the top wall of the flip plate is flush with the top wall of the operating table. The aluminum foil is in contact with the top wall of the flip plate. When the driving component moves downward and to the left, it drives the second hinge component to move to the left along the second slide rail. The second hinge component drives the rotating shaft to move to the left relative to the operating table. The support rod applies an upward thrust to the rotating seat, driving the rotating seat to move upward around the rotating shaft, causing the flip plate to flip up and lift up part of the aluminum foil placed on it. When pressing creases, part of the aluminum foil is clamped and moved downward by the pressure plate and the bending table. The part of the aluminum foil placed on the operating table is lifted with the assistance of the flip plate, reducing the possibility of the aluminum foil being torn when pressing creases. When the driving component resets, the gravity of the flip plate itself drives the support rod and the second hinge component to reset, and the flip plate falls back onto the platform. The relative position of the unloading plate and the bending table can be adjusted by setting an adjustment component, improving the practicality and safety of the unloading plate. The flipping plate is moved in conjunction with the second hinge component and the drive component.

[0022] Optionally, the second hinge includes a movable frame, a short rod, and a control wheel. The bottom end of the movable frame is slidably connected to the second slide rail via a slider, and the top end of the movable frame is rotatably connected to the rotating shaft. The short rod is mounted on the side wall of the movable frame near the bending table. A through hole is provided on the side wall of the operating table for the short rod to pass through. The control wheel is rotatably connected to the end of the short rod away from the movable frame. The control wheel is vertically arranged, and the outer peripheral wall of the control wheel is in contact with the side wall of the driving component near the operating table.

[0023] By adopting the above technical solution, when the driving component is located at the right end of the first slide rail, the movable frame is also located at the right end of the second slide rail, and the outer peripheral wall of the control wheel contacts the side wall of the driving component near the operating table. When the driving component moves downward and to the left relative to the operating table, the driving component drives the control wheel to rotate under the action of friction; at the same time, the control wheel transmits the leftward thrust to the short rod through the shaft, driving the movable frame to move to the left along the second slide rail.

[0024] In summary, this application includes at least one of the following beneficial technical effects: Aluminum foil is partially placed on the operating table and partially located within the bending assembly. The bending assembly presses a crease in the center of the aluminum foil in one operation. Simultaneously, the bending assembly drives the flanging assembly to perform a first right-angle fold on the edge of the aluminum foil; subsequently, the flanging assembly performs a second right-angle fold to form the flange. This application enables automated bending and flanging of aluminum foil; only one positioning is required to accurately press the crease and fold at the designed position, improving the precision of aluminum foil bending and flanging. This facilitates the operator's installation of the formed aluminum foil onto the refrigerator door panel, improving production accuracy and efficiency. Furthermore, the flanging assembly is located on the bending assembly, combining the crease pressing and the first folding actions, shortening the required cycle time, and further improving production efficiency. When the pressure plate just touches the bending table, its bottom wall is flush with the bottom wall of the flanging plate. The lifting plate continues to descend, compressing both the pressure plate and the buffer on the bending table. At this point, the top wall of the bending table is lower than the top wall of the operating table, and the top wall of the flanging plate is lower than the bottom wall of the bending table, completing the crease pressing and the first flanging. The lifting plate remains stationary, and the flanging drive propels the flanging plate horizontally towards the bending table for a second fold to form the flanging. Combining the crease pressing and the first flanging actions shortens the required cycle time and improves production efficiency. Compared to using two cylinders, this equipment can reduce costs. The buffer on the pressure plate allows for relative displacement between the pressure plate and the flanging plate, creating a buffer that effectively reduces the descent speed of the pressure plate and minimizes the possibility of the aluminum foil being torn. The locking assembly locks the movable plate and the flange plate in place only when the relative vertical displacement between the pressure plate and the flange plate reaches the design value. Only then can the flange plate drive the movable plate to move the flange plate. If the pressure plate and the flange plate have not reached the designated position, the flange plate drive can only push the movable plate, and the flange plate remains stationary. By incorporating the locking assembly, damage to the flange plate, pressure plate, and bending table is prevented, thus improving the safety of equipment operation. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0037] Reference Figure 1 To fit the refrigerator door panel, the aluminum foil to be folded needs to be cut into 100mm pieces as follows: Figure 1 The shape shown is used, and a crease 101 is pressed into the middle of the aluminum foil 100, and a flange 102 is folded into the edge of the aluminum foil 100.

[0038] This application discloses a bending device. (Refer to...) Figure 2 The bending equipment includes a frame 1, which is placed on the ground. An operating table 2 for placing aluminum foil 100 is installed inside the frame 1, and the operating table 2 is horizontally mounted on the frame 1 by bolts. Multiple positioning elements 7 are provided on the operating table 2 to limit the position of the aluminum foil 100 on the operating table 2. A bending assembly 3 is provided on the frame 1, and the bending assembly 3 is located on one side of the operating table 2. A portion of the aluminum foil protrudes from the edge of the operating table 2 and is placed within the bending assembly 3. The bending assembly 3 can cooperate with the operating table 2 to press a crease 101 into the aluminum foil 100. A flange assembly 4 is also provided on the bending assembly 3, located on the side of the bending assembly 3 away from the operating table 2. The edge of the aluminum foil 100 that needs to be flanged protrudes from the bending assembly 3, and the flange assembly 4 can cooperate with the bending assembly 3 to fold the edge of the aluminum foil 100 to form a flange 102.

[0039] The operator takes an unclamped sheet of aluminum foil and places it on the operating table 2. Positioning component 7 assists in positioning. At this point, the portion of the aluminum foil closest to positioning component 7 rests on the operating table 2, while the portion furthest from positioning component 7 is located within the bending assembly 3, with the edge of the aluminum foil protruding from the bending assembly 3. The bending assembly 3 works once to press a crease in the center of the aluminum foil. Simultaneously, the bending assembly 3 drives the flanging assembly 4 to perform a first right-angle fold on the edge of the aluminum foil; subsequently, the flanging assembly 4 performs a second right-angle fold to form a flange. This application enables automated bending and flanging of aluminum foil; only one positioning is needed to accurately press a crease and fold at the designed position, improving the accuracy of aluminum foil bending and flanging. This facilitates the operator installing the formed aluminum foil onto the refrigerator door panel, improving production accuracy and efficiency. Furthermore, the flanging assembly 4, located on the bending assembly 3, combines the crease pressing and the first folding actions, shortening the required cycle time and further improving production efficiency.

[0040] Reference Figure 3 Multiple positioning elements 7 surround the edge of the aluminum foil located on the worktable 2. Each positioning element 7 includes a positioning plate 71 with a through hole extending through its thickness. A positioning hole extending through its thickness is also provided on the top wall of the worktable 2. A fixing bolt 73 passes through the positioning plate 71 via the through hole and is threaded onto the inner wall of the positioning hole. The nut of the fixing bolt 73 abuts against the top wall of the positioning plate 71 at the through hole, thus fixing the positioning plate 71 to the worktable 2. The through hole on the positioning plate 71 is a slotted hole 72. The fixing bolt 73 can slide horizontally along a straight section of the inner wall of the through hole, moving the positioning plate 71 within the confines of the slotted hole 72. The sidewalls of the multiple positioning plates 71 can simultaneously contact the edge of the aluminum foil. In this embodiment, four positioning plates 71 are provided according to the shape characteristics of the aluminum foil.

[0041] Positioning holes are pre-drilled on the workbench 2 according to the dimensions of the aluminum foil. The operator installs the positioning plate 71 on the workbench 2 using fixing bolts 73, but does not tighten them immediately. The angle and position of the positioning plate 71 are adjusted so that the side wall of the positioning plate 71 is just in contact with the edge of the aluminum foil. The fixing bolts 73 are then tightened to secure the positioning plate 71. During production, the operator takes an unclamped sheet of aluminum foil, places it on the workbench 2, and moves the aluminum foil so that the edge closest to the operator is against the side wall of the four positioning plates 71. This facilitates the positioning of the aluminum foil and improves the accuracy of the positioning, thereby improving the accuracy of crease pressing and edge turning of the aluminum foil.

[0042] Reference Figure 3 and Figure 4The bending assembly 3 includes a bending table 31, which is located on the side of the operating table 2 near the interior of the frame 1. The bending table 31 is movably mounted on the frame 1, and multiple buffers 5 are provided between the bending table 31 and the frame 1. In this embodiment, eight buffers 5 are provided between the bending table 31 and the frame 1. Each buffer 5 includes a sleeve, a column, and a buffer spring. The column is inserted into the sleeve, and both ends of the buffer spring are glued to the column and the sleeve, respectively.

[0043] The sleeve is bolted to the frame 1, and the column is bolted to the bottom wall of the bending table 31. The bending table 31 can move vertically relative to the operating table 2. Part of the aluminum foil is placed on the operating table 2, and the other part is placed on the bending table 31. The edges of the operating table 2 and the bending table 31 that are close to each other have the same shape as the desired crease.

[0044] A gantry frame is bolted inside the frame 1, and a bending drive component 33 is mounted on the gantry frame. In this embodiment, the bending drive component 33 includes a cylinder and a lifting plate 331. The cylinder is mounted upside down on the top wall of the gantry frame, and its cylinder shaft passes through the top plate of the gantry frame and is bolted to the lifting plate 331 to drive the lifting plate 331 to reciprocate in the vertical direction.

[0045] A pressure plate 32 is installed on the bottom wall of the lifting plate 331, and the pressure plate 32 is located directly above the bending table 31. Multiple buffers 5 are provided between the pressure plate 32 and the lifting plate 331; in this embodiment, eight buffers 5 are provided between the pressure plate 32 and the lifting plate 331. The column is bolted to the bottom wall of the lifting plate 331, and the sleeve is bolted to the top wall of the pressure plate 32. The pressure plate 32 can reciprocate vertically relative to the lifting plate 331. The edge of the pressure plate 32 near the operating table 2 has the same shape as the desired crease. A rubber pad is attached to the contact surface between the pressure plate 32 and the aluminum foil.

[0046] When the buffer 5 on the bending table 31 is in a relaxed state, the top wall of the bending table 31 is flush with the top wall of the operating table 2. The operator places aluminum foil on the operating table 2, with the position where the crease needs to be pressed corresponding to the gap between the operating table 2 and the bending table 31. The lifting plate 331 descends, driving the pressure plate 32 to descend until the pressure plate 32 presses the aluminum foil tightly onto the bending table 31. The lifting plate 331 continues to descend, and both the pressure plate 32 and the buffer 5 on the bending table 31 begin to be compressed. The pressure plate 32 and the bending table 31 together clamp the portion of aluminum foil placed on the bending table 31 and move it downward relative to the operating table 2. At this time, the top wall of the bending table 31 is lower than the top wall of the operating table 2, and the portion of aluminum foil placed on the operating table 2 flips up along the edge of the pressure plate 32, completing the crease pressing. Subsequently, the flanging assembly 4 performs the flanging.

[0047] Reference Figure 4 and Figure 5The flanging assembly 4 includes a flanging plate 41, which slides in conjunction with a lifting plate 331. The flanging plate 41 is an L-shaped plate. A track 43 is bolted to the top wall of the horizontal plate of the flanging plate 41, and a guide rail 44 corresponding to the track 43 is bolted to the bottom wall of the lifting plate 331. Both the track 43 and the guide rail 44 are horizontally arranged, and the length direction of the guide rail 44 extends from the flanging plate 41 toward the pressure plate 32. The flanging plate 41 is located on the side of the pressure plate 32 away from the operating table 2. The edges of the bending table 31 and the pressure plate 32 away from the operating table 2 are adapted to the edge of the aluminum foil that needs to be flanged, and the edge of the flanging plate 41 near the pressure plate 32 is adapted to the edge of the aluminum foil that needs to be flanged.

[0048] A notch is provided on the vertical plate of the flange plate 41, and a movable plate 64 is installed at the notch. A baffle 332 is integrally formed on the bottom wall of the lifting plate 331. The baffle 332 is vertically arranged, and two buffers 5 are provided between the baffle 332 and the movable plate 64. The sleeve is connected to the baffle 332 by bolts, and the column is connected to the movable plate 64 by bolts. A locking assembly 6 is provided on the pressure plate 32, which can lock the movable plate 64 and the flange plate 41.

[0049] A flanging drive component 42 is provided on the frame 1. In this embodiment, the flanging drive component 42 is a cylinder. The flanging drive component 42 is bolted to the frame 1 and is located on the side of the flanging plate 41 away from the pressure plate 32. The cylinder shaft of the flanging drive component 42 can abut against the side wall of the movable plate 64 away from the baffle 332.

[0050] The lifting plate 331 descends, causing the pressure plate 32 and the flange plate 41 to descend vertically. Under the action of the bending table 31, the pressure plate 32 moves upward relative to the flange plate 41. At this time, the top wall of the flange plate 41 is lower than the bottom wall of the bending table 31. The flange plate 41 bends the aluminum foil paper downwards for the first time, protruding from the edge of the bending table 31. Until the lifting plate 331 descends to its lowest point, the pressure plate 32 drives the locking assembly 6 to lock the movable plate 64 and the flange plate 41. At this time, the flange driving component 42 is facing the movable plate 64. The flange driving component 42 pushes the movable plate 64 to move closer to the bending table 31. The buffer 5 connected to the movable plate 64 is compressed. The movable plate 64 drives the flange plate 41 to move closer to the bending table 31. The edge of the flange plate 41 is inserted below the bending table 31, and the edge of the aluminum foil paper is bent a second time after the first bend, forming a flange.

[0051] After the flanging is completed, the cylinder shaft of the flanging drive component 42 retracts and disengages from the movable plate 64. The buffer component 5 connected to the movable plate 64 springs back and drives the movable plate 64 to reset. The movable plate 64 then drives the flanging plate 41 to reset. The lifting plate 331 rises, and the pressure plate 32 and the bending table 31 are both reset under the action of the buffer component 5 connected to them. The locking component 6 releases the connection between the movable plate 64 and the flanging plate 41.

[0052] Reference Figure 5 and Figure 6 The locking assembly 6 includes a connecting rod 62. A movable groove 65 is formed on the top wall of the pressure plate 32, and a round rod is fixed within the movable groove 65. A slider is mounted on the bottom wall of the connecting rod 62, and the slider is fitted onto the round rod and slides in cooperation with it. The slider is connected to the inner wall of the movable groove 65 away from the flange plate 41 by a spring. The length direction of the movable groove 65 is parallel to the driving direction of the flange drive component 42. A locking plate 61 is integrally formed at the end of the connecting rod 62 away from the pressure plate 32, and the locking plate 61 is vertically positioned.

[0053] A wing plate 63 is installed on the side wall of the flange plate 41 near the pressure plate 32. One end of the wing plate 63 is bolted to the flange plate 41, and the other end extends to the movable plate 64. There is a horizontal gap between the wing plate 63 and the movable plate 64. A locking plate 61 can be inserted between the wing plate 63 and the movable plate 64, and the two side walls of the locking plate 61 are respectively attached to the wing plate 63 and the movable plate 64.

[0054] In the initial state, when the pressure plate 32 is flush with the horizontal plate of the flange plate 41, the locking plate 61 is located below the wing plate 63. If the flange drive component 42 is activated at this time, it can only push the movable plate 64, and the flange plate 41 will not be pushed, thus preventing the flange plate 41 from colliding with the pressure plate 32 and the bending table 31.

[0055] Under the action of the bending table 31, the pressure plate 32 rises relative to the flange plate 41. At this time, the slider is located at the right end of the movable groove 65 under the action of the return spring. The pressure plate 32 drives the connecting rod 62 and the locking plate 61 to rise relative to the flange plate 41 through the slider, so that the locking plate 61 is inserted between the wing plate 63 and the movable plate 64. At this time, the flange driving component 42 pushes the movable plate 64, and the movable plate 64 pushes the wing plate 63 through the locking plate 61. The wing plate 63 drives the flange plate 41 to move horizontally. The connecting rod 62 drives the slider to slide to the left along the movable groove, and the return spring is compressed.

[0056] After the flanging is completed, the flanging drive component 42 retracts, and the movable plate 64 resets under the action of the buffer component 5 connected to it, driving the locking plate 61, wing plate 63 and flanging plate 41 to reset, and the connecting rod 62 also resets. Subsequently, the bending drive component 33 drives the lifting plate 331 to rise, and the pressure plate 32 moves downward relative to the pressure plate 32 under the action of the buffer component 5 connected to it. The pressure plate 32 drives the connecting rod 62 and the locking plate 61 to move downward relative to the flanging plate 41 through the slider, so that the locking plate 61 disengages from between the wing plate 63 and the movable plate 64, releasing the lock on the wing plate 63 and the movable plate 64.

[0057] By setting the locking component 6, when the pressure plate 32 and the bending table 31 have not reached the designated position, the flanging drive component 42 can only push the movable plate 64 to move, preventing the flanging plate 41 from colliding with the pressure plate 32 and the bending table 31, thus improving the safety of the equipment.

[0058] Reference Figure 4 and Figure 7 After the aluminum foil is folded over, the folded edge wraps around the edge of the bending table. The operator needs to push the aluminum foil forward to detach it from the bending table 31 before it can be removed. To simplify this process, a ejector plate 9 is slidably mounted on the bottom wall of the bending table 31. The ejector plate 9 is adapted to the shape of the folded edge of the aluminum foil. Multiple ejector plates 9 are provided, and the shape of each ejector plate 9 is the same as the edge shape of the bending table 31 in its corresponding area.

[0059] Reference Figure 7 and Figure 8 The bending table 31 has a driving component 81 on its bottom wall for driving the unloading plate 9. The driving component 81 is a rectangular frame structure with a base plate. A first slide rail 84 is horizontally mounted on the bottom wall of the bending table 31. The top of the driving component 81 has a groove that mates with the first slide rail 84, and the driving component 81 is slidably connected to the first slide rail 84. An elastic element 85 is mounted on the side wall of the driving component 81 near the operating table 2. The end of the elastic element 85 away from the driving component 81 is connected to the first slide rail 84. The elastic element 85 is a spring, and it is stretched when the driving component 81 moves away from the operating table 2. A sloping column 82 is provided directly below the driving component 81 and is fixed to the frame 1 by bolts. The top wall of the sloping column 82 is inclined downwards towards the operating table 2. A rectangular through groove 811 is provided on the base plate of the drive component 81. The rectangular through groove 811 is inclined near the inner wall of the operating table 2 and parallel to the top wall of the slope column 82. The top wall of the slope column 82 is always in contact with the inclined surface of the rectangular through groove 811.

[0060] Reference Figure 8 and Figure 9 A rectangular groove is formed on the top wall of the operating table 2, and a mounting plate 25 is installed on the inner side wall of the groove away from the bending table 31. A flip plate 21 is movably mounted on the operating table 2, and the flip plate 21 has a horizontal state and a flipped state. In the horizontal state, the top wall of the flip plate 21 is flush with the top wall of the operating table 2, and the bottom wall of the flip plate 21 abuts against the top wall of the mounting plate 25 to support the flip plate 21. A rotating seat 212 is fixed to the middle of the bottom wall of the flip plate 21 by bolts. A support rod 22 is rotatably connected to the rotating seat 212. The support rod 22 is inclined downward in the direction away from the bending table 31. The end of the support rod 22 away from the rotating seat 212 is rotatably connected to the inner wall of the groove of the operating table 2 by a shaft. A rotating shaft 211 is fixedly installed on the side wall of the flip plate 21 near the bending table 31, and a second hinge 23 is rotatably connected to the rotating shaft 211.

[0061] The second hinge 23 includes a movable frame 231, the top of which is rotatably connected to a rotating shaft 211. A second slide rail 24 is horizontally mounted on the inner wall of the groove, and the bottom end of the movable frame 231 is slidably connected to the second slide rail 24 via a slider. A short rod 233 is horizontally mounted on the side wall of the movable frame 231 near the bending table, and a through hole is provided on the side wall of the operating table 2 for the short rod 233 to pass through, and the short rod 233 slides along the inner wall of the through hole. A control wheel 232 is provided at the end of the short rod 233 away from the movable frame 231, and the control wheel 232 is rotatably connected to the short rod 233 via a shaft. The control wheel 232 is vertically arranged, and its outer peripheral wall is always in contact with the side wall of the drive member 81 near the operating table 2.

[0062] Reference Figure 7 and Figure 8 A crossbar 812 is installed on the side wall of the drive unit 81 away from the operating table 2. The length of the crossbar 812 is the same as the length of the bending table 31. The drive unit 81 drives the crossbar 812 to reciprocate between the two rows of buffer members 5. The ejector plate 9 is installed on the crossbar 812 through an adjusting member 83. One end of the adjusting member 83 is connected to the ejector plate 9, and the other end is movably connected to the crossbar 812.

[0063] When the top wall of the bending table 31 is flush with the top wall of the operating table 2, the drive component 81 is located at the right end of the first slide rail 84, the side wall of the ejector plate 9 is flush with the side wall of the bending table 31, and the inclined surface of the drive component 81 contacts the highest point of the top wall of the slope column 82; the movable frame 231 is located at the right end of the second slide rail 24, the rotating shaft 211 is located at the right end of the groove, the edge of the flip plate 21 is placed on the mounting plate 25, the top wall of the flip plate 21 is flush with the top wall of the operating table 2, and the aluminum foil is attached to the top wall of the flip plate 21.

[0064] As the bending table 31 begins to descend, a downward thrust is applied to the drive member 81. The slope column 82 applies an upward reaction force to the drive member 82, forcing the drive member 81 to slide downward along the slope. The drive member 81 slides to the left relative to the first slide rail 84, and the elastic member 85 is compressed. The drive member 81 drives the adjusting member 83 and the ejector plate 9 to slide to the left relative to the bending table 31, causing the sidewall of the ejector plate 9 to move away from the sidewall of the bending table 31. Under the action of friction, the drive member 81 drives the control wheel 232 to rotate; at the same time, the control wheel 232 transmits the leftward thrust to the short rod 233 through the shaft. The short rod 233 moves to the left, causing the movable frame 231 to move to the left along the second slide rail 24.

[0065] The movable frame 231 drives the rotating shaft 211 to move to the left relative to the operating table 2. The support rod 22 applies an upward thrust to the rotating seat 212, driving the rotating seat 212 to move upward around the rotating shaft 211 as the center. This causes the flip plate 21 to flip upward, lifting up part of the aluminum foil placed on it. When pressing creases, part of the aluminum foil is clamped and moved downward by the pressure plate 32 and the bending table 31. The part of the aluminum foil placed on the operating table 2 is lifted with the assistance of the flip plate 21, reducing the possibility of the aluminum foil being torn when pressing creases.

[0066] When the bending table 31 rises again, the drive component 81 moves away from the operating table 2 along the first slide rail 84 under the action of the elastic component 85; the flip plate 21 falls back onto the mounting plate 25 under the action of gravity, driving the movable frame 231 back to the right end of the second slide rail 24. The drive component 81 drives the crossbar 812 to move away from the operating table 2, and the crossbar 812 drives the adjusting component 83 and the ejector plate 9 away from the operating table 2. The side wall of the ejector plate 9 contacts the flange of the aluminum foil and pushes the aluminum foil to detach it from the bending table 31.

[0067] Reference Figure 7 and Figure 10 The adjusting component 83 includes a sliding rod 831, which is fixedly mounted on the ejector plate 9. A through hole is formed on the side wall of the crossbar 812, and the sliding rod 831 is slidably disposed within the through hole. The sliding rod 831 is hollow internally, and a through groove is formed on its side wall. An abutment block 832 is telescopically disposed within the through groove, protruding from the side wall of the sliding rod 831 and abutting against the inner wall of the through hole in the crossbar 812. A movable rod 833 is slidably disposed inside the sliding rod 831, and the movable rod 833 engages with the abutment block 832, with the engagement point featuring a beveled fit. The end of the movable rod 833 furthest from the abutment block 832 is connected to the ejector plate 9 via a spring.

[0068] The operator pulls the movable rod 833, causing it to move closer to the ejector plate 9. Under the action of the inclined plane, the abutment block 832 retracts into the sliding rod 831. The operator can then control the sliding rod 831 to insert into the through hole of the crossbar 812. When the ejector plate 9 moves to the appropriate position, the movable rod 833 is released. The movable rod 833 resets, causing the abutment block 832 to extend out of the sliding rod 831 and abut against the inner wall of the through hole. Under the action of friction, the sliding rod 831 is installed on the crossbar 812. The movement of the crossbar 812 causes the sliding rod 831 and the ejector plate 9 to move. When the drive component 81 controls the ejector plate 9 to be in the retracted state, the ejector plate 9 will not collide with the flange plate 41. By setting the adjustment component 83, the relative position of the ejector plate 9 and the bending table 31 can be adjusted, improving the practicality and safety of the ejector plate 9.

[0069] The operating principle of the bending equipment in this application is as follows: Aluminum foil is placed on the operating table 2 and the bending table 31. The pressure plate 32 and the flanging plate 41 descend, driving the bending table 31 below the operating table 2 and the flanging plate 41 below the bending table 31, completing the crease pressing and the first bend. At this time, the flanging plate 21 lifts, assisting the aluminum foil to flip up; the ejector plate 9 retracts; the locking assembly 6 locks the movable plate 64 to the flanging plate 41, and the flanging drive component 42 pushes the movable plate 64 to drive the flanging plate 41 for a second bend, forming a flanged edge. When the bending table 31 resets, the drive component 81 resets, driving the ejector plate 9 to move, assisting the aluminum foil to detach from the bending table 31.

[0070] This application enables automated bending and flanging of aluminum foil, improving the accuracy of these processes. By integrating the flanging component 4 onto the bending component 3, the actions of pressing the crease and the first fold are combined, shortening the work cycle. A locking component 6 reduces the possibility of damage between the flanging plate 41 and other components; the flanging plate 21 is linked to the bending table 31, and the unloading plate 9 is also linked to the bending table 31 to assist in unloading the aluminum foil; thus improving the safety and practicality of the equipment.

[0071] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
