Description

Technical Field

[0001] The invention relates to the technical field of bending of lightning protection lightning strips on roofs, and in particular to a bending device and a bending method for a lightning strip. Background Art

[0002] During thunderstorms, buildings (e.g., the edges and protruding parts of building roofs) are easily struck by lightning. Therefore, lightning-attracting components (e.g., lightning conductors) are usually installed on the buildings. The lightning conductors can conduct the current applied to the buildings by lightning into the earth, thus avoiding safety hazards caused by lightning strikes on the buildings.

[0003] Currently, due to the different shapes of buildings, the lightning rods installed on them need to adapt to the shapes of the buildings.

[0004] In the prior art, the lightning conductor can be obtained by bending the workpiece to be processed (i.e., the raw material of the lightning conductor) by mechanical bending (e.g., mechanical bending, hot bending, or cold bending), or by manually bending the workpiece to be processed.

[0005] However, firstly, if the mechanical bending method is used, the bending cost will be increased, the bending process requires professional personnel to operate, the high temperature in the hot bending method will cause a certain degree of damage to the workpiece to be processed, and the cold bending method has low processing accuracy. Secondly, the processing accuracy of the manual bending method is also low. Thirdly, the shape of the lightning rod obtained by the above method is single and cannot be well adapted to the shape of the building.

[0006] In summary, the processing accuracy of the lightning termination strip obtained by the existing method is low, which will cause a certain degree of damage to the lightning termination strip. Professional equipment and professionals will increase the bending cost, and the lightning termination strip has a single shape.

[0007] Therefore, there is an urgent need for a lightning rod bending device and a bending method, which can not only improve the processing accuracy of the lightning rod, but also have simple operation steps (i.e., no professional technicians are required), and can bend lightning rods of various forms so that the lightning rods can be well adapted to the shape of the building. At the same time, the bending process will not damage the lightning rod, and the device cost is low. Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides a lightning rod bending device and a bending method, which can greatly improve the bending accuracy of the lightning rod and widen the curvature and shape of the lightning rod after bending.

[0009] The present invention provides a lightning rod bending device, characterized by: a first bending mechanism for changing the arc length of the bending arc of the lightning rod, a second bending mechanism for changing the bending shape of the lightning rod, and a supporting mechanism for supporting or placing the first bending mechanism and the second bending mechanism;

[0010] The support mechanism includes a first support plate, a pair of bearing seats fixedly arranged on the upper surface of the first support plate for fixing the first bending mechanism, four first support columns fixedly arranged at the four corners of the lower surface of the first support plate, a pair of second support plates symmetrically fixedly arranged on the outer surface of the first support column for placing the lightning termination strip, and a third support plate fixedly arranged below the first support column for placing the second bending mechanism;

[0011] The first bending mechanism comprises a first bending assembly for bending the lightning termination strip clamped in the bearing seat, the first bending assembly comprises an arc mold for bending the lightning termination strip clamped in the bearing seat, a limiting groove for limiting the bending direction of the lightning termination strip is circumferentially arranged on the outer surface of the arc mold, a driving rod fixedly arranged on the arc mold for driving the arc mold to rotate, an L-shaped guide piece arranged below the arc mold for guiding the bending direction of the lightning termination strip, and an angle rotating disk fixedly arranged at the center of the arc mold for measuring the bending curvature of the lightning termination strip;

[0012] The second bending mechanism includes an angle mold arranged below the first support plate for abutting against the lightning rod, the angle mold includes a first angle mold fixedly arranged below the first support plate and a second angle mold arranged below the first angle mold, the lightning rod is arranged between the first angle mold and the second angle mold, and a jack for lifting the lightning rod upwards is fixedly arranged below the second angle mold.

[0013] The above-mentioned lightning strip bending device is characterized in that the inner diameter of the arc mold is 165mm, 114mm or 90mm.

[0014] The above-mentioned lightning strip bending device is characterized in that the shape of the angle mold is an U-shaped bend, a 135° bend or a 120° bend.

[0015] The above-mentioned lightning strip bending device is characterized in that the second support plate is an L-shaped support plate.

[0016] The above-mentioned lightning-termination strip bending device is characterized in that it also includes a support assembly fixedly arranged on the second support plate for upwardly supporting the lightning-termination strip, and the support assembly includes a bolt passed through the second support plate for adapting the height of the lightning-termination strip, and a nut passed through the bolt for fixing the bolt.

[0017] The present invention also provides a method for bending a lightning conductor using the lightning conductor bending device, which is characterized by comprising:

[0018] The first bending mechanism is used to change the arc length of the bending arc of the lightning termination strip, and the second bending mechanism is used to change the bending shape of the lightning termination strip;

[0019] When the first bending mechanism changes the arc length of the bending arc of the lightning rod, the lightning rod is placed on the L-shaped guide plate, the two ends of the lightning rod are located on the upper surface of a pair of second support plates, the lightning rod is clamped in the limiting groove, the driving rod is rotated, and the arc mold fixedly connected to the driving rod rotates synchronously. When the rotation angle measured by the angle rotating disk is π / 2, the lightning rod arranged on the L-shaped guide plate is bent to form a right-angle bend with an arc of π / 2.

[0020] When the second bending mechanism changes the bending shape of the lightning rod, the lightning rod is placed between the first angle mold and the second angle mold. After the jack fixedly connected to the second angle mold is lifted upward, the lightning rod takes a shape that matches the angle mold.

[0021] The beneficial effect reasoning analysis is as follows:

[0022] In the prior art, the processing precision of the lightning termination strip obtained by the existing method is low, which will cause a certain degree of damage to the lightning termination strip. Professional equipment and professionals will increase the bending cost, and the lightning termination strip has a single shape.

[0023] In the technical solution provided by the present invention, firstly, during the process of the first bending mechanism changing the bending curvature of the lightning rod, when the driving rod drives the arc mold to rotate, the L-shaped guide plate fixedly arranged under the arc mold can rotate synchronously, and the cooperation between the L-shaped guide plate and the second support plate can make the lightning rod arranged thereon rotate synchronously (that is, realize the bending of the lightning rod), when the bending curvature of the lightning rod measured by the angle rotating disk is π / 2, the lightning rod is bent to π / 2, and during the above-mentioned bending process of the lightning rod, the limiting groove can make the two ends of the lightning rod in the width direction be tightly clamped in the above-mentioned limiting groove, so as to avoid displacement of the lightning rod during the bending process.

[0024] Secondly, in the process of changing the bending shape of the lightning rod by the second bending mechanism, the first angle mold fixedly arranged under the first support plate and the second angle mold fixedly arranged above the jack can bend the lightning rod between the first angle mold and the second angle mold into a shape compatible with the angle molds when the jack is lifted upward.

[0025] It is precisely because of the provision of the driving rod, arc mold, limiting groove, angle rotating disk, L-shaped guide plate and second support plate in the first bending mechanism that the bending accuracy of the lightning rod is improved when the lightning rod is bent into a certain arc.

[0026] It is precisely because of the provision of the first angle mold, the second angle mold, and the jack in the second bending mechanism that the bending accuracy of the lightning rod is improved when the lightning rod is bent into a shape that matches the angle mold.

[0027] This avoids the problems in the prior art of bending the lightning conductor through a bending device, such as low bending precision of the lightning conductor, damage to the lightning conductor, high cost of the bending device, high difficulty coefficient of the operation process (i.e., professional technicians are required to operate), and the lightning conductor has a single form and cannot be well adapted to the shape of the building.

[0028] Therefore, the technical solution of the present invention can not only improve the processing accuracy of the lightning rod, but also simplify the operation steps (i.e., no professional technicians are required), and can also bend various forms of lightning rods so that the lightning rods can be well adapted to the shape of the building. At the same time, the bending process will not damage the lightning rod, and the device cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] In the prior art, firstly, if the mechanical bending method is used, the mechanical bending method will increase the bending cost, the bending process requires professional personnel to operate, the high temperature in the hot bending method will cause a certain degree of damage to the workpiece to be processed, and the cold bending method has low processing accuracy.

[0054] Combination Figure 1 4, a lightning conductor bending device provided by the present invention comprises: a first bending mechanism for changing the arc length of the bending arc of the lightning conductor, a second bending mechanism for changing the bending shape of the lightning conductor, and a supporting mechanism for supporting or placing the first bending mechanism and the second bending mechanism;

[0055] The support mechanism comprises a first support plate 1, a pair of bearing seats 2 fixedly arranged on the upper surface of the first support plate 1 for fixing the first bending mechanism, four first support columns 3 fixedly arranged at the four corners of the lower surface of the first support plate 1, a pair of second support plates 4 symmetrically fixedly arranged on the outer surface of the first support column 3 for placing the lightning strip, and a third support plate 5 fixedly arranged below the first support column 3 for placing the second bending mechanism;

[0056] The first bending mechanism comprises a first bending assembly for bending the lightning rod and is clamped in the bearing seat 2. The first bending assembly comprises an arc mold 6 for bending the lightning rod and is clamped in the bearing seat 2. A limiting groove 7 for limiting the bending direction of the lightning rod is circumferentially arranged on the outer surface of the arc mold 6, a driving rod 8 for driving the arc mold 6 to rotate and fixedly arranged on the arc mold 6, an L-shaped guide piece 9 for guiding the bending direction of the lightning rod and arranged below the arc mold 6, and an angle rotating disk 15 for measuring the bending curvature of the lightning rod is fixedly arranged at the center of the arc mold 6.

[0057] The second bending mechanism includes an angle mold arranged below the first support plate 1 for abutting the lightning rod, the angle mold includes a first angle mold 10 fixedly arranged below the first support plate 1 and a second angle mold 11 arranged below the first angle mold, the lightning rod is arranged between the first angle mold 10 and the second angle mold 11, and a jack 12 for lifting the lightning rod upwards is fixedly arranged below the second angle mold 11.

[0058] The lightning termination strip may be a galvanized round steel with an inner diameter of 10 mm to 12 mm.

[0059] The first support plate 1 may be a steel plate with a size of length*width*height=230mm*100mm*10mm, and the size of the second support plate 4 is the same as that of the first support plate 1 .

[0060] The bearing seat 2 is fixedly connected to the first bending mechanism. The specific connection method can be to insert a connecting shaft with a length of 170 mm and an inner diameter of 15 mm into the bearing seat 2, and clamp the first bending mechanism in the bearing seat 2 through the connecting shaft.

[0061] The first supporting column 3 may be an angle steel with a length*width*height=350mm*40mm*40mm.

[0062] The limiting groove 7 can be a groove with a width of 15 mm and a depth of 2 mm (ie, a circumferential circular groove located on the outer surface of the arc mold 6) chiseled out by a groove machine.

[0063] The connection between the L-shaped guide piece 9 and the arc mold 6 can be a detachable threaded connection. In a specific implementation, the lightning rod can be first clamped in the limiting groove 7, and then the L-shaped guide piece 9 and the arc mold 6 are threadedly connected, so that the lightning rod is tightly clamped in the limiting groove 7 and the L-shaped guide piece 9. When the driving rod 8 rotates a certain arc, the lightning rod is also bent by a corresponding arc.

[0064] The driving rod 8 may be a short tube with an inner diameter of 20 mm.

[0065] Optionally, the second angle mold 11 and the jack 12 may be fixedly connected via a connector (pipe cap).

[0066] The angle rotating disk 15 can verify or check whether the actual bending arc is consistent with the expected bending arc.

[0067] It can be understood that the first bending mechanism and the second bending mechanism in the lightning rod bending device provided by the present invention can bend different lightning rods at the same time (that is, the two mechanisms work simultaneously) or independently (that is, the two mechanisms work separately) to bend the lightning rods.

[0068] The beneficial effect reasoning analysis is as follows:

[0069] In the prior art, the processing precision of the lightning termination strip obtained by the existing method is low, which will cause a certain degree of damage to the lightning termination strip. Professional equipment and professionals will increase the bending cost, and the lightning termination strip has a single shape.

[0070] In the technical solution provided by the present invention, firstly, during the process of the first bending mechanism changing the bending curvature of the lightning rod, when the driving rod 8 drives the arc mold 6 to rotate, the L-shaped guide plate 9 fixedly arranged under the arc mold 6 can rotate synchronously, and the cooperation between the L-shaped guide plate 9 and the second support plate 4 can make the lightning rod arranged thereon rotate synchronously (that is, realize the bending of the lightning rod), when the bending curvature of the lightning rod measured by the angle rotating disk 15 is π / 2, the lightning rod is bent to π / 2, and during the above-mentioned bending process of the lightning rod, the limiting groove 7 can make the two ends of the lightning rod in the width direction be tightly clamped in the above-mentioned limiting groove 7, so as to avoid displacement of the lightning rod during the bending process.

[0071] Secondly, in the process of changing the bending shape of the lightning rod by the second bending mechanism, the first angle mold 10 fixedly arranged under the first support plate 1 and the second angle mold 11 fixedly arranged above the jack 12 can bend the lightning rod between the first angle mold 10 and the second angle mold 11 into a shape compatible with the angle molds when the jack 12 is lifted upward.

[0072] It is precisely because of the provision of the driving rod 8, arc mold 6, limiting groove 7, angle rotating disk 15, L-shaped guide plate 9 and second support plate 4 in the first bending mechanism that the bending accuracy of the lightning rod is improved when the lightning rod is bent into a certain arc.

[0073] It is precisely because of the first angle mold 10, the second angle mold 11, and the jack 12 in the second bending mechanism that the bending accuracy of the lightning rod is improved when the lightning rod is bent into a shape that matches the angle mold.

[0074] This avoids the problems in the prior art of bending the lightning conductor through a bending device, such as low bending precision of the lightning conductor, damage to the lightning conductor, high cost of the bending device, high difficulty coefficient of the operation process (i.e., professional technicians are required to operate), and the lightning conductor has a single form and cannot be well adapted to the shape of the building.

[0075] Therefore, the technical solution of the present invention can not only improve the processing accuracy of the lightning rod, but also simplify the operation steps (i.e., no professional technicians are required), and can also bend various forms of lightning rods so that the lightning rods can be well adapted to the shape of the building. At the same time, the bending process will not damage the lightning rod, and the device cost is low.

[0076] In the embodiment described above, a lightning strip bending device is introduced. In another embodiment of the present invention, the specific dimensions of the arc mold 6 are introduced.

[0077] See also Figure 5 The inner diameter of the arc mold 6 is 165mm, 114mm or 90mm.

[0078] The arcs of the lightning termination strips bent by the arc mold 6 with the above inner diameter are the same (for example, both are π / 2), and the arc lengths corresponding to the equal arcs are different. For example, the larger the inner diameter, the longer the arc length.

[0079] Optionally, the length of the arc mold 6 can be 50 mm.

[0080] In a specific implementation, the specific connection process between the bearing seat 2 and the arc mold 6 in the first bending mechanism can be: first, insert the connecting shaft into the bearing seat 2. Second, use a galvanized short pipe with an inner diameter of 90 mm as the shaft and weld three galvanized steel pipes with a length of 30 mm at 120° in the circumferential direction. Third, weld the components welded in the second step into the internal cavity of the arc mold 6. Fourth, clamp the galvanized short pipe with an inner diameter of 90 mm in the center of the arc mold 6 with the connecting shaft to realize the clamping of the first bending mechanism with the bearing seat 2.

[0081] It is understandable that the arc mold 6 with the corresponding inner diameter can be replaced according to actual needs.

[0082] In the above-mentioned embodiment, the specific size of the arc mold 6 is introduced. In another embodiment of the present invention, the specific shape of the angle mold is introduced.

[0083] Referring to FIG. 6 , the shape of the angle mold is an U-shaped bend, a 135° bend or a 120° bend.

[0084] Among them, different angle molds can bend the lightning rod into different shapes to meet the needs of different buildings. See Figure 6. The second angle mold 11 and the jack 12 are connected by a pipe cap (detachable connection), and the angle mold of the corresponding shape can be replaced according to actual needs.

[0085] Optionally, the angle mold can be cut from a steel plate with length*width*height=230mm*100mm*20mm.

[0086] In the above-mentioned embodiment, the specific shape of the angle mold is introduced. In another embodiment of the present invention, the specific shape of the second support plate 4 is introduced.

[0087] See also Figure 1 , the second support plate 4 is an L-shaped support plate.

[0088] The L-shaped support plate is used to provide an upward supporting force to the lightning strip before and during the bending process of the lightning strip by the first bending mechanism.

[0089] In the embodiment described above, the specific shape of the second support plate 4 is introduced. In another embodiment of the present invention, before the first bending mechanism bends the lightning conductor and during the bending of the lightning conductor, the lightning conductor and the second support plate 4 are brought into close contact, thereby making the bending more accurate and highly adaptable.

[0090] Continue to see Figure 1 , and also includes a support assembly fixedly arranged on the second support plate 4 for upwardly receiving the lightning strip, the support assembly includes a bolt 13 passed through the second support plate 4 for adapting the height of the lightning strip, and a nut 14 passed through the bolt 13 for fixing the bolt 13.

[0091] In a specific implementation, the height of the bolt 13 can be adjusted to a degree of close contact with the lightning rod, and then the bolt 13 can be fixed with the nut 14. The lightning rod is in close contact with the bolt 13 directly and with the second support plate 4 indirectly. Therefore, when the first bending mechanism bends the lightning rod into a certain arc, the bending accuracy is high.

[0092] In the embodiment described above, it is introduced that before the first bending mechanism bends the lightning conductor and during the bending process, the lightning conductor is brought into close contact with the second support plate 4, so that the bending is more accurate in the height adaptation component. In another embodiment of the present invention, a method for bending a lightning conductor using the lightning conductor bending device described above is introduced, and the method comprises the following steps:

[0093] The first bending mechanism is used to change the arc length of the bending arc of the lightning termination strip, and the second bending mechanism is used to change the bending shape of the lightning termination strip;

[0094] When the first bending mechanism changes the arc length of the bending arc of the lightning rod, the lightning rod is placed on the L-shaped guide plate 9, the two ends of the lightning rod are located on the upper surface of a pair of second support plates 4, the lightning rod is clamped in the limiting groove 7, the driving rod 8 is rotated, and the arc mold 6 fixedly connected to the driving rod 8 rotates synchronously. When the rotation angle measured by the angle rotating disk 15 is π / 2, the lightning rod set on the L-shaped guide plate 9 is bent to form a right-angle bend with an arc of π / 2;

[0095] When the second bending mechanism changes the bending shape of the lightning rod, the lightning rod is placed between the first angle mold 10 and the second angle mold 11. After the jack 12 fixedly connected to the second angle mold 11 is lifted upward, the lightning rod takes on a shape that matches the angle mold.

[0096] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0097] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
