Description

Technical Field

[0001] This application belongs to the field of metal processing equipment technology, and specifically relates to a flat steel bending processing device. Background Technology

[0002] The installation of lightning protection grounding engineering is crucial for the safety of equipment and facilities involving a large number of electronic components, such as strong and weak current rooms, air conditioning rooms, and refrigeration rooms. Among these, the exposed grounding flat steel, as a conductive grounding element, is an indispensable part of the project. In the existing technology, there are two conventional methods for horizontally bending flat steel: one is to cut and weld the flat steel on site into connectors with an included angle of 90 degrees, and weld diagonal bracing at the connection to increase the contact area and optimize the performance of the connection. This method is labor-intensive and time-consuming, and the final product has poor appearance quality, making it unsuitable for many occasions. The second method is to purchase pre-made flat steel parts for bending on the market. This is not economical and efficient, and the replaceability of purchased parts is poor, making it impossible to adapt to different working conditions according to actual construction.

[0009] Furthermore, the interlocking distance between the upper and lower discs is adjustable to accommodate different types of flat steel thicknesses.

[0010] Furthermore, the upper disc, the first rotating support, and the second rotating support are fixed by threaded connections to prevent the upper disc from loosening due to gravity and centrifugal force during rotation.

[0011] Furthermore, the first and second rotating support members are provided with shaft caps at the top of their rotating shafts to prevent axial displacement, and the shaft caps are fixed to the rotating shafts by threaded connections.

[0012] Furthermore, the fastener has a locking interface to secure the distal end of the flat steel piece.

[0031] A specific embodiment of this utility model discloses a flat steel bending processing device, comprising:

[0032] The base plate 1 can be set into various different shapes and structures, such as circular, square, and triangular, depending on the specific working environment and processing conditions. The base plate 1 is provided with a rotating shaft 101 as the rotation axis and positioning point of other structures in this utility model.

[0033] Preferably, the base plate 1 is provided with a plurality of positioning holes 102 for fixing the base plate 1 on the working plane, so as to prevent the base plate 1 from being misaligned due to the friction of the rotating plate 3 during the bending of the flat steel parts, which would lead to human error.

[0034] Fixing member 2, installed on base plate 1, is used to fix one end of the flat steel piece during bending. In this embodiment, see [reference needed]. Figure 3 The fixing component 2 is a fixing block with a clamping interface 201. The flat steel component to be processed is fixed by clamping it into the clamping interface 201.

[0035] In some other embodiments, the fixing member 2 may be a pressure plate with a groove adapted to the thickness of the flat steel member, or it may be a clamp with adjustable spacing set on the base plate 1. No specific limitation is made here.

[0036] Furthermore, the fastener clip interface 201 is provided with an adjustment device 202 for adjusting the size of the fastener clip interface 201. In this embodiment, the clip interface 201 is a U-shaped groove opened on the fixing block 2, and the surface for contacting the flat steel piece is threaded through in a direction perpendicular to the contact surface. The adjustment device 202 is a wide-mouth screw screwed into the thread of the clip interface 201. By adjusting the depth of the screw entering the groove, the working size of the clip interface 201 can be adjusted to adapt to the clamping needs of flat steel pieces of different thicknesses. In some other embodiments, the adjustment device 202 is a telescopic structure set at the bottom of the U-shaped groove, and the size of the clip interface 201 can be adjusted by the telescopic structure.

[0037] The rotating plate 3 is provided with a mounting hole 301 and a mounting shaft 302. The rotating plate 3 is rotatably mounted on the rotating shaft of the base plate 1 through the mounting hole 301, so that the rotating plate 3 can rotate around the rotating shaft 101 as the rotation center; at the same time, the mounting shaft 302 is used to position and install the second rotating support 5.

[0038] Preferably, the contact surface between the base plate 1 and the rotating plate 3 is made of low-damping materials such as cast iron, so as to avoid excessive friction between the base plate 1 and the rotating plate 3, which would prevent the rotating plate 3 from rotating smoothly and increase the difficulty of bending processing.

[0039] In some embodiments, a ring of gaskets is provided on the base plate 1 near the rotating shaft 101 to reduce the direct contact area between the rotating plate 3 and the base plate 1, thereby reducing the friction between the rotating plate 3 and the base plate 1.

[0040] Furthermore, in some embodiments, the surface of the base plate 1 facing the rotating plate 3 is provided with several support pads. The support pads are used to support the rotating plate 101 and ensure that it is located on the expected working horizontal plane. This arrangement reduces the friction between the rotating plate 3 and the base plate 1, while preventing the rotating plate from becoming unbalanced due to different support angles.

[0041] This utility model embodiment also includes: a first rotating support member 4 and a second rotating support member 5, both of which are disposed on the rotating plate 3. The flat steel piece to be processed is clamped between the two to achieve support and bending of the flat steel piece to be processed. The first rotating support member 4 is rotatably mounted on the rotating shaft 101 of the base plate 1 and rotates coaxially with the rotating plate 3. The second rotating support member 5 is rotatably mounted on the mounting shaft 302 of the rotating plate 3, so that it can rotate around the mounting shaft 302 of the rotating plate 3, while the mounting shaft 302 will revolve synchronously with the rotating plate 3 around the rotating shaft 101 of the base plate 1.

[0042] Specifically, the mounting holes 301 and mounting shaft 302 on the rotating plate 3 should be set at a certain distance to ensure that after the first rotating support 4 and the second rotating support 5 are installed, the distance between them is sufficient to clamp and support the flat steel piece to be processed.

[0043] Furthermore, the portions of the first rotating support 4 and the second rotating support 5 that come into contact with the curvature of the flat steel piece during rotation should be arcs to ensure the flatness of the curved portion of the final finished flat steel piece. In this embodiment, both the first rotating support 4 and the second rotating support 5 are cylinders. It should be noted that, depending on the specific usage requirements and appearance needs, the first rotating support 4 and the second rotating support 5 can be other geometric shapes such as semi-cylinders or irregular geometric shapes, as long as the portion that comes into contact with the expected curvature of the flat steel piece is an arc. In this embodiment, cylinders are used to pursue the overall aesthetics of the device.

[0044] In this embodiment, both the first rotating support 4 and the second rotating support 5 are fitted with an upper disc 6 and a lower disc 7. The upper disc 6 is fitted onto the top of the rotating support 4 and 5, and the lower disc 7 is fitted onto the bottom of the rotating support 4 and 5 and contacts the rotating plate 3. A gap is left between the two discs to clamp the flat steel piece to be processed in the axial direction. During the bending process, while the flat steel piece abuts against the rotating support 4 and 5, it is clamped by the upper disc 6 and the lower disc 7 to prevent the flat steel piece from axially disturbing during the bending process, which would affect the surface flatness of the final finished flat steel bent piece.

[0045] It should be noted that since the upper disc 6 and the lower disc 7 are only responsible for restricting the degree of freedom of the rotation axis of the flat steel piece to be processed, and do not directly participate in the contact with the flat steel piece to be processed in the predetermined bending direction, it is not necessary to ensure the curvature of their edges. Specifically, there is no need to restrict the shape of the upper disc 6 and the lower disc 7. According to the actual usage requirements and appearance requirements, they can be triangular discs, square discs, irregular discs, etc., and no specific limitation is made here. In this embodiment, in order to pursue the overall aesthetics of the device, they are set to a disc shape.

[0046] Preferably, the fitting positions of the upper disc 6 and the lower disc 7 onto the rotating support members 4 and 5 can be changed, thereby changing the clamping distance between the upper disc 6 and the lower disc 7 to accommodate the thickness of flat steel parts of different sizes, making the clamping of the flat steel parts by the upper disc 6 and the lower disc 7 more stable.

[0047] Preferably, the first rotating support 4 and the second rotating support 5 are detachably fixedly connected to their respective upper disks 6 to prevent misalignment and loosening between the upper disks 6 and the rotating supports 4 and 5 due to external forces such as internal friction and gravity during rotation, which would affect the mechanical efficiency of the device. In this embodiment, the fixed connection between the two is a threaded connection. In some other embodiments, other detachable connection methods can also be used, such as snap-fit ​​closure or cylindrical pin connection.

[0048] In some other embodiments, both the first rotating support 4 and the second rotating support 5 are provided with staged mounting slots for mounting clamping devices. This allows the flat steel piece to be processed to be bent and rotated against the rotating support 4 and 5 while being clamped by the clamping devices, thus preventing the flat steel piece from moving up and down during the bending process and affecting the surface flatness of the final finished flat steel bent piece. The specific installation position of the clamping devices can be adjusted within the mounting slot range to achieve stable clamping of flat steel pieces of different thicknesses. In this embodiment, the clamping devices replace the upper disc 6 and the lower disc 7, making the overall device simpler and more compact while achieving the same technical effect.

[0049] In this embodiment, the top ends of the first rotating support 4 and the second rotating support 5 are provided with shaft caps 9. The shaft caps 9 are firmly sleeved on the mounting shaft of the rotating support to prevent axial displacement, and the shaft caps 9 are fixed to the rotating shaft by threaded connection.

[0050] Preferably, the rotating plate 3 is provided with a force-enhancing grip 303, the surface of which is provided with a high-friction material, such as rubber, polyurethane, or frosted metal base. In this embodiment, the force-enhancing grip 303 is a grip handle with a frosted surface, which is welded to the end of the rotating plate 3 away from the rotating shaft 101. Depending on the specific usage scenario, the length of the grip handle is set to be as long as possible while meeting the material rigidity requirements, so as to increase the lever arm length during the bending and rotation of the flat steel piece, making it easier for the operator. At the same time, the high-friction frosted surface of the handle effectively avoids accidental situations such as slippage and loss of hand during operation.

[0051] Specifically, the specific method for bending flat steel parts in this embodiment of the present invention is as follows: one end of the flat steel part to be processed is clamped and fixed to the clamping interface 201 of the fixing part 2; according to the specific target bending angle requirements of the flat steel bending part, the rotating plate 3 is rotated so that the line connecting the rotation axes of the first rotating support 4 and the second rotating support 5 intersects the direction line of the flat steel part that is fixed with the flat steel part at a predetermined design bending angle. Unless there are special actual working needs, this angle is 90 degrees; the flat steel part is simultaneously fixed and abutted against the first rotating support 4 and the second rotating support 5, and the rotating plate 3 is rotated so that the second rotating support 5 rotates synchronously with it and bends the flat steel part to be processed. At the same time, the first rotating support 4 and the second rotating support 5 rotate along their respective rotation axes, thereby ensuring the bending flatness of the inner curve and the outer curve of the flat steel bending part. The bending part made in this way is not only quick and convenient to meet the design requirements, but also has a flat bend and is more aesthetically pleasing than the flat steel bending parts in the prior art.

[0052] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this application. It should be understood that the above description is only a specific embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
