Description

Technical Field

[0001] This utility model belongs to the technical field of lamp post processing, specifically relating to a sheet metal bending device. Background Technology

[0002] During the manufacturing process of light poles, the cut steel plates need to be bent. When bending, the steel plate is usually placed between the bending die and the pressure plate. The pressure plate squeezes the steel plate into the bending die, so that the steel plate forms a bend that is consistent with the bending die.

[0003] There are many types of light poles. Even for a single shape, such as a frustum, the number of sides of the frustum will vary depending on the usage scenario, which in turn will result in different bending angles.

[0004] However, most of the bending dies in current bending devices have fixed angles, which means that the steel plate can only form a single angle during the extrusion process, resulting in the problem of low applicability of bending devices. Utility Model Content

[0057] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0058] Please refer to the following: Figures 1 to 3 This invention describes a sheet metal bending device. The sheet metal bending device includes a bottom mold unit 10, a compaction unit 20, and a conveying unit 30. The bottom mold unit 10 includes a mold table 101, a first rotating plate 102 rotatably connected to the mold table 101, a second rotating plate 103 rotatably connected to the mold table 101, and a drive assembly drivingly connected to the first rotating plate 102 and the second rotating plate 103. The drive assembly drives both the first rotating plate 102 and the second rotating plate 103 to rotate about a first direction as their rotation axis, with the first rotating plate 102 and the second rotating plate 103 rotating in opposite directions. The compaction unit 20 includes a pressure structure disposed above the mold table 101. The pressure structure extends and retracts in the vertical direction, and the extending end of the pressure structure is used to compress the steel sheet to be bent. The conveying unit 30 is connected to the mold table 101 and is used to move the position of the steel sheet to be bent.

[0059] In the plate bending device provided in this embodiment, before bending the steel plate, the operator determines the required bending angle and drives the first rotating plate 102 and the second rotating plate 103 to rotate through the driving component, so that the included angle between the first rotating plate 102 and the second rotating plate 103 is equal to the required bending angle. Then, the operator conveys the steel plate to be bent to the preset position of the bottom mold unit 10 through the conveying unit 30. Finally, the pressure structure presses the steel plate to be bent downward to the angle between the first rotating plate 102 and the second rotating plate 103, so that the steel plate is bent to the preset angle.

[0060] Compared with the prior art, by driving the first rotating plate 102 and the second rotating plate 103 to rotate through the driving component, the first rotating plate 102 and the second rotating plate 103 are brought closer to each other or moved away from each other, realizing the stepless adjustment of the angle between the first rotating plate 102 and the second rotating plate 103, thereby adapting to different bending angle requirements and improving the applicability of the bending device.

[0061] In some embodiments, see Figure 3 The first rotating plate 102 and the second rotating plate 103 are each provided with multiple plates spaced apart along the first direction. The driving assembly includes a rotating rod 104, a first power component 105, a sleeve rod 106, and a second power component 107. The rotating rod 104 is rotatably connected to the table surface of the mold table 101 and is fixedly connected to all the first rotating plates 102. The first power component 105 is drivenly connected to the rotating rod 104 and is used to drive the rotating rod 104 to rotate around the first direction as the rotation axis. The first power component 105 is a servo motor. The sleeve rod 106 is rotatably connected to the outer periphery of the rotating rod 104. The sleeve rod 106 has arc-shaped grooves 1061 that correspond one-to-one with the first rotating plates 102 along the first direction. The second rotating plates 103 are correspondingly provided in the arc-shaped grooves 1061 and are fixedly connected to the outer wall of the sleeve rod 106. The second power component 107 is drivenly connected to the sleeve rod 106 and is used to drive the sleeve rod 106 to rotate around the first direction as the rotation axis. The second power component 107 is a servo motor.

[0062] The first power component 105 drives the rotating rod 104 to rotate, which in turn rotates the first rotating plate 102, thereby adjusting the angle of the first rotating plate 102. The second power component 107 drives the sleeve rod 106 to rotate, which in turn rotates the second rotating plate 103, thereby adjusting the angle of the second rotating plate 103. The first power component 105 and the second power component 107 work together to adjust the angle between the first rotating plate 102 and the second rotating plate 103, and also to adjust the orientation of the angle between the first rotating plate 102 and the second rotating plate 103. Since the sleeve rod 106 is sleeved on the outer circumference of the rotating rod 104, the rotation axes of the first rotating plate 102 and the second rotating plate 103 are coaxial, and the angle between the first rotating plate 102 and the second rotating plate 103 is the final finished product angle of the mold table 101.

[0063] In some embodiments, see Figure 1 and Figure 3 The bottom mold unit 10 also includes a first compensation plate 108, a third power component 109, a second compensation plate 110, and a fourth power component 111. The first compensation plate 108 is rotatably connected to the first rotating plate 102, and the rotation axis of the first compensation plate 108 is perpendicular to the axial direction of the rotating rod 104. The third power component 109 is drivenly connected to the first compensation plate 108 and is used to drive the first compensation plate 108 to rotate. The third power component 109 is a servo motor. The second compensation plate 110 is rotatably connected to the second rotating plate 103, and the rotation axis of the second compensation plate 110 is perpendicular to the axial direction of the sleeve rod 106. The fourth power component 111 is drivenly connected to the second compensation plate 110 and is used to drive the second compensation plate 110 to rotate. The fourth power component 111 is a servo motor.

[0064] The first compensation plate 108 is driven to rotate by the third power component 109, so that the gap between two adjacent first rotating plates 102 can be filled. At the same time, the second compensation plate 110 is driven to rotate by the fourth power component 111, so that the gap between two adjacent second rotating plates 103 can be filled. The first compensation plate 108 and the second compensation plate 110 increase the contact area with the steel plate to be bent, so that the steel plate to be bent is subjected to uniform force during the compression process.

[0065] In some embodiments, see Figure 2 The bottom mold unit 10 also includes support components. Multiple support components are arranged in a row along the first direction, and two rows of support components are arranged along the second direction. One row of support components is used to abut against the first rotating plate 102, and the other row of support components is used to abut against the second rotating plate 103.

[0066] The support assembly includes a first telescopic member 112 and a retaining plate 113. The first telescopic member 112 is fixed to the surface of the mold table 101. The telescopic direction of the first telescopic member 112 is perpendicular to the surface direction of the mold table 101. The first telescopic member 112 is a telescopic oil cylinder or hydraulic cylinder. The retaining plate 113 is rotatably connected to the telescopic end of the first telescopic member 112. The retaining plate 113 rotates about a first direction.

[0067] After the first compensation plate 108 and the second compensation plate 110 are both flipped to the preset position, one row of the first telescopic members 112 is activated, so that the abutting plate 113 abuts against the first rotating plate 102 and the first compensation plate 108. At the same time, the other row of the first telescopic members 112 is activated, so that the abutting plate 113 abuts against the second rotating plate 103 and the second compensation plate 110. This provides abutment support for the first rotating plate 102 and the second rotating plate 103, making the force on the steel plate more uniform during the bending process.

[0068] In some embodiments, see Figure 1 and Figure 2The bottom mold unit 10 also includes a base 114 and a fifth power component 115. The mold table 101 is rotatably connected to the base 114. A conversion slot 1011 is provided on one side of the mold table 101. The fifth power component 115 is connected to the mold table 101 for driving the mold table 101 to rotate around the first direction as the rotation axis. The fifth power component 115 is a servo motor.

[0069] The fifth power component 115 drives the mold table 101 to rotate, so that the table surface with the first rotating plate 102 and the second rotating plate 103 and the table surface with the conversion groove 1011 are interchanged, thereby realizing the conversion between the two modes of frustum bending and cylindrical bending. This can adapt to different bending requirements and further improve the applicability of the sheet metal bending device.

[0070] In some embodiments, see Figure 1 The bottom mold unit 10 also includes an arc block 116 that is detachably connected to the inner wall of the conversion groove 1011.

[0071] During the production process, the angle of the curved light poles of different heights is different during the bending process, so arc blocks 116 with different curvatures are required. The detachable arc blocks 116 are adapted to various steel plates to be bent at different bending angles, which further improves the applicability of the plate bending device.

[0072] In some embodiments, see Figure 1 The compaction unit 20 includes a mounting base 201, a sliding base 202, and a moving component 203. The mounting base 201 is located above the bottom mold unit 10. The sliding base 202 is slidably connected to the mounting base 201 and slides along a second direction. A pressurizing structure is located on the sliding base 202. The moving component 203 is drivenly connected to the sliding base 202 and is used to drive the sliding base 202 to move. Specifically, the moving component 203 is a gear and rack transmission method, which is conventional technology and will not be described in detail in this application.

[0073] The sliding seat 202 is driven to slide by the moving component 203, so that the position of the pressurizing structure is adjustable, thereby ensuring that the pressurizing structure is always in the optimal stress state under any circumstances.

[0074] In some embodiments, see Figure 1 and Figure 2 The pressurization structure includes a first pressurization component and a second pressurization component.

[0075] The first pressurizing assembly includes a first pressurizing plate 204, a second telescopic member 205, two side plates 206, and multiple third telescopic members 207. The first pressurizing plate 204 is located below the sliding seat 202. The second telescopic member 205 is fixedly connected between the sliding seat 202 and the first pressurizing plate 204, and extends and retracts in the vertical direction. The second telescopic member 205 is a telescopic oil cylinder or hydraulic cylinder. The two side plates 206 are respectively located on both sides of the first pressurizing plate 204 along a second direction. The side plates 206 are rotatably connected to the first pressurizing plate 204, and the side plates 206 are rotated about the first direction. The first pressurizing assembly has multiple third telescopic members 207 corresponding to the side plates 206. Three telescopic components 207 are arranged at least one at intervals along the first direction and grouped into a row. The third telescopic component 207 is arranged in two rows. The two rows of third telescopic components 207 are respectively arranged on both sides of the first pressure plate 204 along the second direction. One end of the third telescopic component 207 is rotatably connected to the first pressure plate 204. The rotation axis of the fixed end of the third telescopic component 207 is parallel to the first direction. The telescopic end of the third telescopic component 207 is slidably connected to the side plate 206. The sliding direction of the third telescopic component 207 is perpendicular to the first direction. The telescopic direction of the third telescopic component 207 is perpendicular to its own rotation axis. The third telescopic component 207 is a telescopic oil cylinder or hydraulic cylinder.

[0076] The second pressurizing assembly includes a fixed base 208, a fourth telescopic member 209, and a second pressurizing plate 210. The fixed base 208 is located below the sliding base 202. The fourth telescopic member 209 is fixed between the sliding base 202 and the fixed base 208. The fourth telescopic member 209 extends and retracts in the vertical direction. The fourth telescopic member 209 is a telescopic oil cylinder or a hydraulic cylinder. The second pressurizing plate 210 is detachably connected to the fixed base 208.

[0077] The sliding seat 202 is driven to slide by the moving component 203, so that the first pressing component and the second pressing component move to the top of the mold table 101 respectively, thereby corresponding to different bending modes and realizing different bending requirements.

[0078] When it is necessary to switch to a cylindrical lamp post bending, the second telescopic component 205 retracts, causing the first pressure plate 204 to move upward. At the same time, the moving component 203 drives the sliding seat 202 to slide, so that the second pressure plate 210 moves above the mold table 101. The fifth power component 115 starts synchronously to rotate the conversion slot 1011 to the top. At this time, the transformation from truncated pyramid lamp post bending to cylindrical lamp post bending is completed.

[0079] When it is necessary to switch to the frustum-shaped lamp post bending, the fourth telescopic component 209 retracts, causing the second pressure plate 210 to move upward. At the same time, the moving component 203 drives the sliding seat 202 to slide, so that the first pressure plate 204 moves above the mold table 101. The fifth power component 115 is activated simultaneously to rotate the side table with the first rotating plate 102 and the second rotating plate 103 to the top. At this time, the transformation from cylindrical lamp post bending to frustum-shaped lamp post bending is completed.

[0080] During the bending of the truncated pyramid shape of the lamp post, if the angle of the bent steel plate needs to be adjusted, the third telescopic component 207 extends and retracts, causing the side plate 206 to gradually rotate relative to the first pressure plate 204. This causes the third telescopic component 207 to slide on the side plate 206, while the side plate 206 rotates relative to the first pressure plate 204. When the included angle formed by the two side plates 206 rotates to a preset angle, the third telescopic component 207 stops moving. By extending and retracting the third telescopic component 207, the two side plates 206 can be brought closer together or moved further apart, thus achieving stepless adjustment of the included angle between the two side plates 206.

[0081] In some embodiments, see Figure 1 and Figure 2 Two conveying units 30 are provided, and the two conveying units 30 are respectively arranged on both sides of the mold table 101 along the second direction. The conveying unit 30 includes a fifth telescopic member 301, a transport table 302, and two sixth telescopic members 303. The fifth telescopic member 301 is fixed to the ground, and at least one fifth telescopic member 301 is arranged at intervals along the first direction. The fifth telescopic member 301 extends and retracts in the vertical direction. The fifth telescopic member 301 is a telescopic oil cylinder or a hydraulic cylinder. The transport table 302 is fixed to the telescopic end of the fifth telescopic member 301. The two sixth telescopic members 303 are respectively arranged at both ends of the transport table 302 along the first direction. The sixth telescopic members 303 extend and retract in the second direction. The sixth telescopic members 303 are telescopic oil cylinders or hydraulic cylinders.

[0082] During the bending process of the steel plate, due to the inconsistency of the final shape of the light pole, there are isosceles trapezoidal steel plates or rectangular steel plates. Therefore, it is necessary to mark the bending points in advance during the bending process so that the upper and lower bases of the isosceles trapezoid are on the same straight line.

[0083] Under the action of the sixth telescopic member 303, the four corners of the isosceles trapezoidal steel plate or rectangular steel plate can be pressed together. According to the marked position of the bending point, the extension length of each sixth telescopic member 303 is different, so that the bending point on the steel plate to be bent can be accurately placed in the extrusion area during the conveying process of the steel plate to be bent.

[0084] Because the first rotating plate 102 and the second rotating plate 103 rotate at different angles, while their lengths remain constant, their final heights after rotation are different. This necessitates that the highest points of the first rotating plate 102 and the second rotating plate 103 be matched during the conveying of the steel plate to be bent. The fifth telescopic component 301 ensures that the transport platform 302 is always at the same height as the first rotating plate 102 and the second rotating plate 103, guaranteeing the transport efficiency of the steel plate to be bent and preventing damage to the steel plate caused by the height difference.

[0085] In some embodiments, see Figure 1 and Figure 2 The transmission unit 30 also includes a clamping assembly corresponding to the sixth telescopic member 303. The clamping assembly includes a side abutment plate 304 and a sixth power member 305. The side abutment plate 304 is rotatably connected to the free end of the sixth telescopic member 303, and the rotation axis of the side abutment plate 304 is perpendicular to the first direction. The sixth power member 305 is drively connected to the side abutment plate 304 and is used to drive the side abutment plate 304 to rotate. The sixth power member 305 is a servo motor.

[0086] It should be noted that the side abutment plate 304 has a flexible pad on the side facing the steel plate to be bent.

[0087] During the process of the sixth telescopic component 303 pressing against the steel plate to be bent, the steel plate no longer maintains a horizontal state after being squeezed multiple times. The setting of the pressing plate 113 allows steel plates of any shape to be pressed against, and the bending state of the steel plate will not be damaged under the action of the flexible pad. At the same time, under the action of the sixth power component 305, the plate surface direction of the pressing plate 113 is always kept parallel to the side of the steel plate to be bent.

[0088] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
