Description

Technical Field

[0001] This utility model belongs to the field of rounded corner production technology, specifically a rounded corner sheet metal equipment. Background Technology

[0002] Sheet metalworking is a processing technique, and there isn't a single, comprehensive definition. According to a definition published in a foreign professional journal, it can be defined as: Sheet metalworking is a comprehensive cold-working process for thin metal sheets (usually less than 6mm), including shearing, punching / cutting / combined cutting, bending, riveting, splicing, and forming (such as car bodies). Its most significant characteristic is that the thickness of the same part is consistent.

[0003] Currently, some existing rounded corner sheet metal equipment bends metal sheets to fit the surface of a bending mold using bending components. However, the shape of the bending mold is relatively fixed. When the bending angle needs to be changed, the bending mold needs to be replaced. Changing the bending angle is relatively time-consuming and labor-intensive, and relatively inconvenient to use. Therefore, we propose a rounded corner sheet metal equipment to solve or improve the above problems. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a rounded corner sheet metal equipment, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a rounded corner sheet metal equipment, comprising a workbench, a support plate fixed to the top of the workbench, a first mold plate rotatably mounted on the surface of the support plate via a rotating shaft, a second mold plate rotatably mounted on the top of the first mold plate via a rotating shaft, a first connecting plate rotatably mounted on the bottom of the first mold plate via a rotating shaft, a second connecting plate inserted inside the first connecting plate, a first threaded rod rotatably mounted on the top of the workbench via a bearing, an mounting plate sleeved on the surface of the first threaded rod, a connecting rod inserted inside the mounting plate, a placement plate fixed to the top of the connecting rod, a spring sleeved on the surface of the connecting rod, and a second threaded rod inserted inside the workbench.

[0007] Furthermore, a first limiting rod is fixed to the top of the worktable. Several sets of the first limiting rods are symmetrically fixed to the top of the worktable, and the top of the first limiting rod passes through the interior of the mounting plate and is slidably connected to the mounting plate.

[0008] Furthermore, a second limiting rod is fixed inside the worktable. Several sets of the second limiting rods are symmetrically fixed inside the worktable. The second limiting rods pass through the interior of the second connecting plate and are slidably connected to the second connecting plate.

[0009] Furthermore, the second threaded rod passes through the interior of the second connecting plate and is threadedly connected to the second connecting plate.

[0010] Furthermore, several sets of connecting rods are symmetrically inserted inside the mounting plate, and the number of springs is the same as the number of connecting rods.

[0011] Furthermore, a limiting plate is fixed to the top of the first limiting rod, and a limiting plate is fixed to the bottom of the connecting rod.

[0012] Compared with the prior art, the present invention has the following advantages: by setting a second threaded rod, a second connecting plate, a first connecting plate, a first mold plate, and a second mold plate, when it is necessary to change the bending angle, the second threaded rod can be rotated to drive the two sets of second connecting plates to move towards each other, thereby causing the second connecting plate to drive the first connecting plate to move. When the first connecting plate moves, it will drive one end of the second mold plate and the first mold plate to move towards each other, thereby adjusting the angle between the first mold plate and the second mold plate, thus adjusting the bending angle. Changing the bending angle is relatively time-saving and labor-saving, and is relatively convenient to use. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figure 1-5As shown, this utility model is a rounded corner sheet metal equipment, including a workbench 1, a support plate 10 fixed to the top of the workbench 1, and two sets of first mold plates 6 rotatably mounted on the surface of the support plate 10 via a rotating shaft, and second mold plates 8 rotatably mounted on the top of the first mold plate 6 via a rotating shaft. The positions of the second mold plate 8 and the first mold plate 6 are symmetrical. The tops of the first mold plate 6 and the second mold plate 8 share a set of rotating shafts, and a first connecting plate 11 rotatably mounted on the bottom of the first mold plate 6 via the rotating shafts. When the first connecting plate 11 moves, it will drive one end of the first mold plate 6 to move. Simultaneously, the first connecting plate 11 is also rotatably mounted on the bottom of the second mold plate 8 via a rotating shaft. The positions of the first connecting plates 11 are symmetrical. Similarly, when the other set of first connecting plates 11 moves, it will drive one end of the rotatably connected second mold plate 8 to move. The second connecting plate 13 is inserted inside the first connecting plate 11. The first connecting plate 11 and the second connecting plate 13 are slidably connected. The number of second connecting plates 13 is the same as the number of first connecting plates 11. A limit block is provided inside the first connecting plate 11. The limit block is located inside the second connecting plate 13 and is slidably connected to the second connecting plate 13. The limit block can restrict the position of the second connecting plate 13 to prevent the second connecting plate 13 from falling out of the inside of the first connecting plate 11. When the second connecting plate 13 moves, it will drive the slidably connected first connecting plate 11 to move. A second limit rod 12 is fixed inside the worktable 1. Several sets of second limiting rods 12 are symmetrically fixed inside the worktable 1. The second limiting rods 12 pass through the interior of the second connecting plate 13 and are slidably connected to the second connecting plate 13. The second limiting rods 12 can restrict the position of the second connecting plate 13, preventing the second connecting plate 13 from tilting or shaking when moving, thus improving the stability of the second connecting plate 13 when moving. The second threaded rod 14 is inserted inside the worktable 1. The surface of the second threaded rod 14 is symmetrically provided with two sets of threads in opposite directions. The second threaded rod 14 passes through the interior of the second connecting plate 13 and is threadedly connected to the second connecting plate 13. The second threaded rod 14 passes through the interior of two sets of second connecting plates 13 and is threadedly connected to both sets of second connecting plates 13, and the two sets of second connecting plates 13 are respectively located at the first... On both sides of the surface of the second threaded rod 14, when the second threaded rod 14 rotates, it will drive the two sets of threaded second connecting plates 13 to move towards each other, thereby causing the second connecting plates 13 to drive the two sets of rotatably connected first connecting plates 11 to move towards each other, and causing the two sets of first connecting plates 11 to drive the rotatably connected first mold plate 6 and second mold plate 8 to move one end, so that they rotate around the pivot at the top end of the second mold plate 8. The first threaded rod 7 is rotatably mounted on the top of the worktable 1 through bearings. Two sets of first threaded rods 7 are symmetrically mounted on the top of the worktable 1. The mounting plate 2 is sleeved on the surface of the first threaded rod 7 and is threadedly connected to the first threaded rod 7. When the first threaded rod 7 rotates, it will drive the threadedly connected mounting plate 2 to move. A first limit rod 9 is fixed on the top of the worktable 1.Several sets of first limiting rods 9 are symmetrically fixed on the top of the workbench 1. The top of the first limiting rods 9 passes through the interior of the mounting plate 2 and is slidably connected to the mounting plate 2. The several sets of first limiting rods 9 can restrict the position of the mounting plate 2, preventing the mounting plate 2 from tilting or shaking when moving, thus improving the stability of the mounting plate 2 when moving. A limiting plate is fixed to the top of the first limiting rods 9, which can restrict the position of the mounting plate 2 and prevent the mounting plate 2 from detaching from the surface of the first limiting rods 9 from the top side. Connecting rods 4 are inserted into the interior of the mounting plate 2. Several sets of connecting rods 4 are symmetrically inserted into the interior of the mounting plate 2. A limiting plate is fixed to the bottom of the connecting rods 4, which can restrict the position of the connecting rods 4 and prevent the connecting rods 4 from detaching from one side of the mounting plate 2. Placement plates 5 are fixed to the top of the connecting rods 4. Two sets of placement plates 5 are symmetrically arranged on the inner side of the mounting plate 2. When the placement plates 5 move, they will drive the fixed connecting rods 4 to move. The surfaces of the two sets of placement plates 5 contact the surfaces of the first mold plate 6 and the second mold plate 8, respectively. Spring 3 is sleeved on the... On the surface of the connecting rod 4, one end of the spring 3 contacts the surface of the mounting plate 2, and the other end contacts the surface of the placement plate 5. When the placement plate 5 moves, it compresses the spring 3, causing the spring 3 to deform. When there is no external interference, the spring 3 pushes the placement plate 5 to move. At the same time, the spring 3 can apply a certain pressure to the placement plate 5, keeping it always in close contact with the surface of the first mold plate 6 or the second mold plate 8. The number of springs 3 is the same as the number of connecting rods 4. By rotating the first threaded rod 7, the first threaded rod 7 can drive the threaded mounting plate 2 to move, thereby causing the mounting plate 2 to drive the internally inserted mounting plate 2 to move. When the mounting plate 2 moves, it will drive the internally inserted connecting rod 4 to move, thereby causing the connecting rod 4 to drive the fixed placement plate 5 to move, thus changing the height of the placement plate 5. This allows the placement plate 5 to adapt to metal sheets of different sizes, making it easier for personnel to place metal sheets of different sizes on the surface of the placement plate 5 and tilt it against the surface of the first mold plate 6 or the second mold plate 8, facilitating sheet metal operations and improving the equipment's adaptability to metal sheets of different sizes.

[0022] Working principle: When it is necessary to produce a rounded corner, a thin metal sheet is placed on the surface of the placement plate 5 and made to rest against the surface of the first mold plate 6 or the second mold plate 8. At this time, the metal sheet is pressed against the surface of the second mold plate 8 and the first mold plate 6 by bending and pressing it through the bending component (existing technology, not shown in the figure), so that it is bent at a certain angle, thereby completing the production of the rounded corner. When it is necessary to change the bending angle, the second threaded rod 14 is rotated to drive the two sets of second connecting plates 13 to move towards each other, thereby causing the second connecting plate 13 to drive the first connecting plate 11 to move. When the first connecting plate 11 moves, it will drive one end of the second mold plate 8 and the first mold plate 6 to move towards each other, so that the first mold plate 6 and the second mold plate 8 rotate around the pivot at the top of the first mold plate 6, thereby adjusting the angle between the first mold plate 6 and the second mold plate 8, thereby adjusting the bending angle. Changing the bending angle is relatively time-saving and labor-saving, and is relatively convenient to use.

[0023] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
