Description

Technical Field

[0001] This utility model relates to processing equipment for metal products, and in particular to a tabletop flanging machine suitable for large-sized metal discs. Background Technology

[0002] In the field of metal processing, the flanging process is a crucial step in shaping the edges of metal discs and meeting the diverse design and usage requirements of products, and its importance cannot be underestimated. Current flanging equipment generally uses upper and lower pressure plates to clamp the metal disc, and then relies on rotation to achieve edge flanging through a flanging device. For example, a multi-functional edge rolling machine disclosed on March 13, 2018, with publication number CN107790533A, has a frame, a rotating table for supporting the workpiece on the frame, a clamping device above the rotating table, and an edge rolling device on one side of the rotating table; its characteristic is that a trimming device is provided on the other side of the rotating table, and a flanging device is provided on a third lateral position of the rotating table. In essence, the metal disc is rotated by the pressure plates, and the flanging device flanging the edge.

[0003] To achieve precise folding only at the very edge of the metal disc during flanging, while ensuring other parts remain unaffected, the dimensions of the upper and lower pressure plates must be precisely matched to the metal disc. This ensures that the edge to be flanged is exposed precisely during clamping. However, this conventional operating method becomes extremely difficult when processing large metal discs, as the replacement of the upper and lower pressure plates becomes exceptionally challenging. Due to their large weight and size, the replacement of large pressure plates requires the coordinated efforts of multiple operators. The entire replacement process is cumbersome and highly prone to various safety accidents, seriously threatening the personal safety of the operators.

[0004] Furthermore, for metal discs of different sizes, corresponding pressure plates are required. Enterprises not only have to invest a lot of money to purchase pressure plates of various specifications, but also have to reserve enough space and resources for the storage and maintenance of these pressure plates, which undoubtedly greatly increases the production costs of enterprises. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a tabletop flanging machine suitable for large-sized metal discs. This tabletop flanging machine does not require changing the entire lower pressure plate according to the size of the metal disc during flanging, and is suitable for flanging metal discs of various sizes.

[0006] To solve the above technical problems, the following technical solution is adopted: A tabletop flanging machine suitable for large-sized metal discs includes a frame, a rotary table, a clamping device, a trimming device, and a flanging device. The rotary table, clamping device, and trimming device are respectively mounted on the frame. The flanging device is movably mounted on the frame. The upper end of the rotary table is provided with a lower pressure plate coaxially arranged with the rotary table. The clamping device is provided with an upper pressure plate, which is located above the lower pressure plate, and the axis of the upper pressure plate is collinear with the axis of the lower pressure plate. The trimming device and the flanging device are arranged radially around the rotary table. The machine is characterized by further including a tray, which is movably mounted on the frame and located inside the flanging device. Both the tray and the flanging device are located radially from the lower pressure plate. The upper surface of the tray is flat, and the upper surface of the tray is coplanar with the upper surface of the lower pressure plate.

[0007] The aforementioned inward and outward directions are determined based on the axis of the rotary table. The position closer to the axis of the rotary table is considered inward, and the position farther from the axis of the rotary table is considered outward. When using the aforementioned flanging tabletop machine, the metal disc to be flanged is placed on the lower pressure plate. The upper pressure plate in the clamping device descends and works with the lower pressure plate to clamp the metal disc. At this time, the outer edge of the metal disc protrudes beyond the edge of the lower pressure plate. At the position of the flanging device, the tray supports the outer edge of the metal disc. The flanging device initially retracts outward, not contacting the metal disc. Subsequently, the rotary table drives the metal disc to rotate, and the edge of the metal disc is first trimmed by the trimming device. When the trimmed portion of the metal disc rotates to the flanging device, the outer edge of the metal disc, supported by the tray, leaves only the edge to be flanged protruding from the tray. At this time, the flanging device moves inward and contacts the metal disc, continuously flanging the portion of the metal disc to be flanged at the tray until the entire edge of the metal disc is flanged. When flanging large metal discs, this type of desktop flanging machine can support the edge of the metal disc through a tray platform during the flanging process. Therefore, with this setting, there are no special requirements for the size of the upper and lower pressure plates. It can eliminate the need to adapt the upper or lower pressure plates to different metal disc sizes, effectively reducing costs, improving efficiency, and avoiding dangers during disassembly and assembly.

[0008] The aforementioned edge trimming device can adopt existing designs, such as the same structure as the edge trimming device in CN108213968A or CN107790533A.

[0009] In a preferred embodiment, the pallet platform includes a first translation frame and a pallet column. The frame is provided with at least one inward-facing first guide rail. The first translation frame has a first guide groove that matches the first guide rail. The first translation frame is movably mounted on the first guide rail. The lower end of the pallet column is mounted on the first translation frame, and the upper surface of the pallet column is on the same plane as the upper surface of the lower pressure plate. The position of the pallet column can be adjusted by moving the first translation frame inwards and outwards according to the flange requirements of different metal discs.

[0010] In a further preferred embodiment, the flanging device includes a second translation frame, a translation drive device capable of driving the second translation frame away from or near the rotary table, a clamping wheel, a flanging wheel, and a moving drive mechanism capable of driving the flanging wheel away from or near the axis of the clamping wheel. The translation drive device is mounted on the frame. The second translation frame is provided with a second guide groove that matches the first guide rail. The second translation frame is movably mounted on the first guide rail. The clamping wheel is rotatably mounted on the second translation frame. The moving drive mechanism is mounted on the second translation frame. The flanging wheel and the clamping wheel are arranged vertically and staggered in the inward and outward directions. The tray is located inside the clamping wheel. Depending on the required flanging position of different metal discs, the first translation device drives the second translation frame to adjust to a suitable position, so that the flanging wheel and clamping wheel correspond to the edge of the metal disc that needs to be flanged. The moving drive mechanism drives the flanging wheel closer to the axis of the clamping wheel, so that the flanging wheel partially overlaps with the clamping wheel in the horizontal direction, thereby allowing the edge of the metal disc to be flanged according to the gap shape between the clamping wheel and the flanging wheel. Both the first and second translation frames move along the first guide rail, ensuring that the tray column is always inside the flanging device and corresponds to the position of the clamping wheel.

[0011] In a further preferred embodiment, the flanging device further includes a first lifting seat and a first lifting drive device capable of driving the first lifting seat to rise and fall. The second translation frame is provided with a second guide rail running vertically, and the first lifting seat is provided with a third guide groove matching the second guide rail. The first lifting seat is movably mounted on the second guide rail, and the clamping wheel is rotatably mounted on the first lifting seat. The first lifting drive device is mounted on the second translation frame, and the first lifting seat is driven to the power output end of the first lifting drive device. The moving drive mechanism includes a second lifting seat and a second lifting drive device capable of driving the second lifting seat to rise and fall. The first lifting seat is provided with a third guide rail running vertically, and the second lifting seat is provided with a fourth guide groove matching the third guide rail. The second lifting seat is movably mounted on the third guide rail, and the flanging wheel is mounted on the second lifting seat. The second lifting drive device is mounted on the first lifting seat, and the second lifting seat is driven to the power output end of the second lifting drive device. When certain flanging requires bending to a specific angle, the edge of the metal disc can be engaged between the flanging wheel and the clamping wheel. The flanging wheel and clamping wheel are then driven to rise and fall together, achieving the special flanging of the metal disc's edge. Depending on the requirements, the flanging wheel can be rotatably mounted on the second lifting seat or fixedly mounted thereon. Furthermore, depending on the flanging requirements, the axis of the flanging wheel can be parallel to the axis of the clamping wheel or offset from it (i.e., the axis of the clamping wheel is on a horizontal plane, while the axis of the flanging wheel can be on a horizontal plane or at a certain angle to the horizontal plane). Simultaneously, the shape of the flanging wheel can also be customized, for example, it can be cylindrical or frustum-shaped.

[0012] In the preferred embodiment, the upper pressure plate is smaller than the lower pressure plate. Because the flanging tabletop machine uses the above structure and method for flanging, the size requirements for the upper and lower pressure plates are relatively low; the lower pressure plate can be larger for better support. Furthermore, this method allows the flanging tabletop machine to be adapted for flanging small metal discs by simply replacing the lower pressure plate when needed.

[0013] In a preferred embodiment, the rotary table includes a rotary base and a rotary drive device capable of driving the rotary base to rotate. The rotary drive device is mounted on the frame, and the rotary base is rotatably mounted on the frame and is connected to the power output end of the rotary drive device. The rotary drive device can employ a combination of a motor and a reducer, with the reducer mounted on the power output shaft of the motor and the rotary base mounted on the power output shaft of the reducer.

[0014] In a preferred embodiment, the pressing device includes a pressing table and a third lifting drive device capable of driving the pressing table to rise and fall. The third lifting drive device is mounted on the frame, and the pressing table is connected to the power output end of the third lifting drive device. The upper pressure plate is mounted on the lower end of the pressing table.

[0015] The aforementioned translation drive device, first lifting drive device, second lifting drive device and third lifting drive device can all be cylinders.

[0016] The beneficial effect of this utility model is that this flipping desktop machine does not require replacing the entire lower pressure plate according to the size of the metal disc when flipping, and is suitable for flipping metal discs of various sizes. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figure 1-3 The tabletop flanging machine shown is suitable for large-size metal discs and includes a frame 1, a rotary table 2, a pressing device 3, a trimming device 4, a flanging device 5, and a tray table 6. The rotary table 2, the pressing device 3, and the trimming device 4 are respectively mounted on the frame 1. The flanging device 5 and the tray table 6 are respectively movably mounted on the frame 1. The upper end of the rotary table 2 is provided with a lower pressure plate 7 coaxially arranged with the rotary table 2. The pressing device 3 is provided with an upper pressure plate 8, which is located above the lower pressure plate 7, and the axis of the upper pressure plate 8 is in the same straight line as the axis of the lower pressure plate 7. The trimming device 4 and the flanging device 5 are arranged radially around the rotary table 2. The tray table 6 is located inside the flanging device 5. Both the tray table 6 and the flanging device 5 are located radially on the lower pressure plate 7. The upper surface of the tray table 6 is flat, and the upper surface of the tray table 6 is in the same plane as the upper surface of the lower pressure plate 7.

[0019] The aforementioned inner and outer directions are determined based on the axis of the rotary table 2. The position closer to the axis of the rotary table 2 is the inner position, and the position farther away from the axis of the rotary table 2 is the outer position. When using the above-mentioned flanging tabletop machine, the metal disc to be flanged is placed on the lower pressure plate 7. The upper pressure plate 8 in the clamping device 3 descends and works with the lower pressure plate 7 to clamp the metal disc. At this time, the outer edge of the metal disc protrudes outside the edge of the lower pressure plate 7. At the position of the flanging device 5, the tray 6 supports the outer edge of the metal disc. At this time, the flanging device 5 first retracts outward and does not contact the metal disc. Then, the rotating table 2 drives the metal disc to rotate. The edge of the metal disc is first trimmed by the trimming device 4. When the trimmed part of the metal disc rotates to the flanging device 5, the outer edge of the metal disc, supported by the tray 6, only the edge to be flanged protrudes from the tray 6. At this time, the flanging device 5 moves inward and contacts the metal disc, continuously flanging the part of the metal disc to be flanged at the tray 6 until the entire edge of the metal disc is flanged. When this type of tabletop flanging machine flanging large metal discs, the tray platform 6 supports the edge of the metal disc during the flanging process. Therefore, with this setting, there are no special requirements for the size of the upper pressure plate 8 and the lower pressure plate 7. It can achieve the goal of not needing to adapt the upper pressure plate 8 or the lower pressure plate 7 to different metal disc sizes, effectively reducing costs, improving efficiency, and avoiding dangers during disassembly and assembly.

[0020] The aforementioned edge trimming device 4 can adopt existing designs, such as the same structure as the edge trimming device 4 in CN108213968A or CN107790533A.

The lower end of the pallet post 602 is mounted on the first translation frame 601, and the upper surface of the pallet post 602 is on the same plane as the upper surface of the lower pressure plate 7.

The moving drive mechanism 505 is mounted on the second translation frame 501. The flanging wheel 504 and the clamping wheel 503 are arranged vertically and staggered in the inward and outward directions. The tray 6 is located inside the clamping wheel 503. Depending on the required flanging position of different metal discs, the first translation device drives the second translation frame 501 to adjust to a suitable position, so that the flanging wheel 504 and the clamping wheel 503 correspond to the edge of the metal disc that needs to be flanged. The moving drive mechanism 505 drives the flanging wheel 504 to move closer to the axis of the clamping wheel 503, so that the flanging wheel 504 partially overlaps with the clamping wheel 503 in the horizontal direction, so that the edge of the metal disc can be flanged according to the gap shape between the clamping wheel 503 and the flanging wheel 504. Both the first translation frame 601 and the second translation frame 501 move along the first guide rail 101, which ensures that the tray column 602 is always inside the flanging device 5 and corresponds to the position of the clamping wheel 503.

When certain flanging requires bending to a specific angle, the edge of the metal disc can be engaged between the flanging wheel 504 and the clamping wheel 503. The flanging wheel 504 and the clamping wheel 503 are then driven to rise and fall together, achieving a special flanging of the metal disc's edge. Depending on the requirements, the aforementioned flanging wheel 504 can be rotatably mounted on the second lifting seat 5051 or fixedly mounted on the second lifting seat 5051. Furthermore, depending on the flanging requirements, the axis of the flanging wheel 504 can be parallel to the axis of the clamping wheel 503 or offset from it (i.e., the axis of the clamping wheel 503 is on a horizontal plane, while the axis of the flanging wheel 504 can be on a horizontal plane or at a certain angle to the horizontal plane). At the same time, the shape of the flanging wheel 504 can also be set as needed, for example, it can be cylindrical or frustum-shaped.

[0024] The upper pressure plate 8 is smaller than the lower pressure plate 7. Because the flanging tabletop machine uses the above structure and method for flanging, the size requirements for the upper pressure plate 8 and the lower pressure plate 7 are relatively low.

Furthermore, this method allows the flanging tabletop machine to be used for flanging small metal discs by simply replacing the lower pressure plate 7 when needed.
