Description

Technical Field

[0001] This utility model relates to the field of metal product bending technology, specifically to a strip-shaped metal product bending device. Background Technology

[0002] Metal products are products made from metal. Metal products are increasingly widely used in various fields of industry, agriculture and people's lives. However, some strip-shaped metal products need to be bent by a bending device in actual use.

[0003] A search revealed that patent application CN201911130014.4 discloses a bending device for strip-shaped metal products. While this device, through the setup of a fixing device and a bending device, allows the workpiece to be detachably mounted within the fixing device, and the bending device is located on one side of the fixing device to bend the workpiece protruding above the fixing device, the device includes a bending frame positioned on the side of the fixing device away from the guide block. A driving device is located at the upper end of the bending frame, with its driving end horizontally facing the upper end of the fixing device. A bending component is horizontally mounted on the driving end, allowing the driving device to drive the bending component to move horizontally towards the upper end of the fixing device to bend the strip-shaped metal product protruding above the guide hole. However, this device can only perform bending operations at one angle, significantly limiting its application range. In actual production, metal products often require bending at multiple angles to meet different design requirements. Therefore, the device's function is relatively limited and lacks flexibility. Furthermore, due to its limitation to fixed-angle bending, the device has poor adaptability to metal products of different specifications and materials. In practice, frequent equipment changes or process parameter adjustments may be necessary, increasing production costs and operational complexity. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bending device for strip-shaped metal products, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A bending device for strip-shaped metal products includes a base plate, on which a handle and a support plate are rotatably mounted. A metal part to be processed is placed on the support plate, and the metal part is bent by pushing it with the handle.

[0007] Bolts are installed on the base plate, and the handle is rotatably mounted on the base plate via bolts. The support plate is supported and mounted on the base plate via a second pad, and the support plate is limited above the handle by bolts. A support roller is mounted on the support plate by bolts. An extrusion roller is rotatably mounted on the handle. The handle drives the extrusion roller to push the metal part along the outside of the support roller for bending operation with the bolt as the center.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, a fixing frame is installed on the support plate, and an electromagnet is installed on the support plate through the fixing frame. The electromagnet is connected to an external power source through a power line. During the bending operation, the electromagnet attracts and fixes the metal part.

[0010] The beneficial effects of adopting the above-mentioned further solutions are:

[0011] The introduction of electromagnets provides a more convenient and stable way to fix metal parts. By using electromagnetic force to attract metal parts, the fixation is not only firm but also effective for fixing metal parts of different materials and shapes, greatly improving the applicability and flexibility of the device. At the same time, the electromagnet's switching control is simple, allowing operators to quickly fix and release metal parts, thus improving work efficiency.

[0012] Furthermore, a support wheel is rotatably mounted on one side of the fixed frame on the support plate, and during the bending operation, the support wheel provides reverse support to the other end of the metal part.

[0013] The beneficial effects of adopting the above-mentioned further solutions are:

[0014] The support rollers effectively balance the forces acting on the metal parts during bending, preventing deformation or breakage caused by uneven stress. Simultaneously, the rotating design of the support rollers allows for smoother movement of the metal parts during bending, reducing friction with the equipment and extending its lifespan. Furthermore, the support rollers provide stable support for the metal parts, ensuring bending accuracy and consistency.

[0015] Furthermore, the handle is provided with a plurality of fixing holes at various positions, and the extrusion wheel is mounted on the handle by means of fixing holes at different positions as needed.

[0016] The beneficial effects of adopting the above-mentioned further solutions are:

[0017] The design with multiple fixing holes allows the position of the extrusion rollers to be flexibly adjusted according to the size of the metal part and bending requirements. This adjustability not only increases the applicability of the device, but also ensures that the extrusion rollers can apply a more uniform and stable force when pushing the metal part to bend, thereby improving the bending accuracy and consistency.

[0018] Furthermore, a first pad is installed on the handle, and the upper surface of the first pad is on the same horizontal plane as the support plate.

[0019] The beneficial effects of adopting the above-mentioned further solutions are:

[0020] The first pad allows the handle to move more smoothly when pushing the metal part to bend, preventing the metal part from wobbling or shifting due to the height difference between the handle and the support plate. At the same time, the first pad also acts as a buffer and shock absorber, reducing the impact and vibration on the metal part during bending, and protecting the surface quality and integrity of the metal part.

[0021] Furthermore, the extrusion wheel and the support wheel are respectively provided with a first limiting plate and a second limiting plate. During the bending operation, the metal part is limited from above by the first limiting plate and the second limiting plate.

[0022] The beneficial effects of adopting the above-mentioned further solutions are:

[0023] The first and second limiting plates effectively restrict the movement range of the metal part during bending, preventing inaccurate bending or equipment damage caused by the metal part wobbling. Simultaneously, the limiting plates provide additional support and guidance for the metal part, allowing it to move more stably along the predetermined trajectory during bending, thereby improving bending accuracy and consistency. Furthermore, the limiting plates also protect the metal part from excessive compression or stretching during bending, preventing damage.

[0024] This utility model provides a bending device for strip-shaped metal products. It has the following beneficial effects:

[0025] Using an electromagnet to hold metal parts in place ensures their stability during bending, preventing inaccurate bending or equipment damage caused by slippage or displacement of the metal parts. This fixing method is convenient and quick, and the electromagnet's attraction force can be adjusted as needed.

[0026] The support rollers provide reverse support to the other end of the metal part during bending operations. This helps balance the forces acting on the metal part during bending, preventing deformation or breakage due to uneven stress. Simultaneously, the support rollers reduce friction between the metal part and the equipment, extending the equipment's lifespan.

[0027] The extrusion rollers can be mounted on the handle and positioned according to different needs via fixing holes, allowing the device to adapt to the bending requirements of metal parts of different sizes and shapes. This adjustability increases the flexibility and applicability of the device.

[0028] The first and second limiting plates can limit the movement of the metal part from above during the bending operation, which helps to ensure the accuracy and consistency of the bending. By limiting the range of movement of the metal part during the bending process, inaccurate bending caused by the metal part shaking can be avoided. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1 to 3 As shown, the embodiments provided by this utility model are as follows:

[0038] Example 1

[0039] A bending device for strip-shaped metal products includes a base plate 8, a handle 1 and a support plate 7 rotatably mounted on the base plate 8, a metal part to be processed is placed on the support plate 7, and the metal part is pushed by the handle 1 to perform a bending operation.

[0040] Example 2

[0041] To facilitate bending operations of sheet metal with different degrees of curvature and to ensure bending accuracy, for example, such as Figures 1 to 3As shown, this utility model also includes: a bolt 3 installed on the base plate 8, a handle 1 rotatably mounted on the base plate 8 via the bolt 3, a support plate 7 supported on the support plate base plate 8 via a second pad 11, and the support plate 7 is limited above the handle 1 by the bolt 3, a first pad 10 is installed on the handle 1, and the upper end surface of the first pad 10 is at the same level as the support plate 7. The setting of the first pad 10 enables the handle 1 to move more smoothly when pushing the metal part to bend, avoiding the shaking or displacement of the metal part caused by the height difference between the handle 1 and the support plate 7. Meanwhile, the first pad 10 can also play a role in buffering and shock absorption, reducing the impact and vibration of the metal parts during bending, and protecting the surface quality and integrity of the metal parts. The support plate 7 is equipped with a support roller 4 by bolt 3, and the extrusion roller 2 is rotatably installed on the handle 1. The handle 1 has multiple fixing holes 101 evenly opened at multiple positions. The extrusion roller 2 is installed on the handle 1 by fixing holes 101 at different positions as needed. The design of multiple fixing holes 101 allows the position of the extrusion roller 2 to be flexibly adjusted according to the size of the metal parts and bending requirements. This adjustability not only expands the applicability of the device but also ensures that the extrusion roller 2 applies a more uniform and stable force when bending the metal part, thereby improving the bending accuracy and consistency. The handle 1 drives the extrusion roller 2 to bend the metal part along the outer side of the support roller 4, with the bolt 3 as the center. A fixing frame 5 is installed on the support plate 7, and an electromagnet 6 is mounted on the support plate 7 through the fixing frame 5. The electromagnet 6 is connected to an external power source via a power line 601. During the bending operation, the electromagnet 6 attracts and fixes the metal part. The introduction of the electromagnet 6 provides a more convenient and stable way to fix the metal part. Attracting the metal part using electromagnetic force not only provides a firm fixation effect but also enables effective fixing of metal parts of different materials and shapes, greatly improving the applicability and flexibility of the device. Meanwhile, the electromagnet 6 has simple switching control, allowing operators to quickly fix and release metal parts, improving work efficiency. A support wheel 9 is rotatably mounted on one side of the support plate 7, located on the fixed frame 5. During bending operations, the support wheel 9 provides reverse support to the other end of the metal part. The support wheel 9 effectively balances the force on the metal part during bending, preventing deformation or breakage due to uneven force. Furthermore, the rotating design of the support wheel 9 allows the metal part to move more smoothly during bending, reducing friction with the equipment and extending its service life.Furthermore, the support wheel 9 provides stable support for the metal part, ensuring bending accuracy and consistency. The extrusion wheel 2 and the support wheel 9 are respectively equipped with a first limiting plate 201 and a second limiting plate 901. During bending, the first limiting plate 201 and the second limiting plate 901 limit the metal part from above. The first limiting plate 201 and the second limiting plate 901 effectively limit the movement range of the metal part during bending, preventing inaccurate bending or equipment damage caused by metal part swaying. Simultaneously, the limiting plates provide additional support and guidance for the metal part, allowing it to move more stably along a predetermined trajectory during bending, thereby improving bending accuracy and consistency. In addition, the design of the limiting plates also protects the metal part from excessive compression or stretching during bending, preventing damage.

[0042] Working principle:

[0043] The device includes a base plate 8, a handle 1, a support plate 7, a support roller 4, a pressing roller 2, an electromagnet 6, and a support roller 9. Before operation, the metal part to be processed is placed on the support plate 7 and fixed in place by the electromagnet 6. The electromagnet 6 is connected to an external power source via a power line 601, generating magnetic force to attract the metal part and ensure its stability during the bending process.

[0044] Based on the size of the metal part and the bending requirements, select a suitable fixing hole 101 to limit and install the extrusion roller 2 on the handle 1. The position of the extrusion roller 2 is adjustable, allowing the device to adapt to the bending requirements of metal parts of different sizes and shapes.

[0045] The operator uses handle 1 to push the metal part to bend it. Handle 1 is rotatably mounted on the base plate 8 and is limited and fixed by bolt 3. During the bending process, the extrusion roller 2 pushes the metal part along the outside of the support roller 4 with the bolt 3 as the center. At the same time, the support roller 9 provides reverse support to the other end of the metal part, balancing the force on the metal part during the bending process and preventing it from deforming or breaking due to uneven force.

[0046] During the bending process, the first limiting plate 201 and the second limiting plate 901 respectively limit the metal part from above. These two limiting plates can restrict the range of movement of the metal part during the bending process and avoid inaccurate bending caused by the metal part shaking.

[0047] When the metal part reaches the desired bending angle, stop pushing the handle 1. At this point, the power supply to the electromagnet 6 can be disconnected to release the attraction force on the metal part, allowing the bent metal part to be removed from the device.
