Description

Technical Field

[0001] This utility model belongs to the field of sheet metal bending and forming technology, and in particular relates to a sheet metal curvature bending device. Background Technology

[0002] The roofs of smart rest stations are usually designed with curved sides. This is not only to distribute loads such as snow or external impacts to improve overall stability, but also to promote the rapid flow of rainwater to both sides, preventing water accumulation that could lead to ceiling corrosion or leakage, and extending the service life of the station.

[0003] Existing curved bending devices cannot fix the bending position when bending sheet metal, resulting in significant errors in the bending position of the same batch of sheet metal. For example, Chinese utility model patent CN201821843500.1, entitled "Sheet Metal Bending Device," discloses a device including a base plate, a bending die, and a driving device. The bending die includes a die seat, a bending concave die, a bending convex die, and two pads. The die seat is connected to the base plate, and the bending concave die is connected to the die seat. The bending concave die has a cavity, and the two pads are located on both sides of the cavity opening, with guide arcs on the pads. The bending convex die is placed on the die seat and positioned directly in front of the cavity. The driving device includes a driving device base connected to the base and a jack. The jack is connected to the driving device base, and the piston rod of the jack is connected to the convex die. The jack can drive the bending convex die into or away from the cavity. During bending, the bending point of the sheet metal is aligned with the cavity, and the piston rod of the jack drives the bending convex die to bend the sheet metal.

[0004] Although this method is simple in structure and easy to transport, the bending position is only positioned by a positioning plate on one side. During the bending process, both ends of the board may detach from the positioning plate, which may cause the bending position to shift. This can result in a large error in the bending position of the board after bending, affecting the installation quality. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a sheet metal curvature bending device that can accurately position the bending position of the sheet metal during the bending process, reducing the error in the bending position of sheets in the same batch, thus facilitating assembly.

[0006] In order to achieve the purpose of this utility model, the following solution is proposed: A sheet metal curvature bending device includes an operating table, a bending component rotatably mounted at one end of the operating table, and a positioning component located in the middle of the operating table. The bending component includes a set of symmetrically arranged clamping plates, which are arranged along the width of the operating table. The two ends of the clamping plates are respectively connected to the same rotating rod. One end of the rotating rod is rotatably connected to the operating table through a rotating pin. One end of one of the rotating rods is equipped with a motor, which is installed on one side of the operating table. The positioning component includes a cylinder, with vertical supports at both ends of the cylinder, which are movable in the vertical direction.

[0007] Furthermore, the operating table has recessed right-angle grooves on both sides, and a rotating rod is set on the right-angle groove. One end of the rotating rod is rotatably connected to the vertical side wall of the right-angle groove, and the other end extends out of the operating table and is rotatably provided with a connecting seat. The two ends of a set of clamping plates are respectively connected to the connecting seat.

[0008] Furthermore, the rotating rod is a telescopic rod, and the connecting seat is located at the output end of the rotating rod.

[0009] Furthermore, one of the clamping plates has a vertical baffle in the middle.

[0010] Furthermore, vertical slots are provided on both sides of the top surface of the operating table. A vertical support is slidably installed in the slot. A cylinder is provided at the lower end of the vertical support. The output end of the cylinder is vertically connected to the lower end of the vertical support, and the cylinder is installed on the bottom surface of the operating table.

[0011] Furthermore, the upper end of the vertical support is provided with a threaded hole, and a connecting bolt is provided in the threaded hole. The connecting bolt is connected to both ends of the cylinder respectively.

[0012] The beneficial effects of this utility model are as follows: A vertically extendable support is installed perpendicular to the top surface of the worktable. The bending position and bending radius of the sheet metal are fixed by a cylinder between the two vertical supports. The end of the sheet metal extending from the worktable is clamped by a clamping plate, and the connecting seats at both ends of the clamping plate are rotatably connected to the rotating rod. This ensures that the distance between the bending position of the sheet metal and the end of the sheet metal extending from the worktable remains consistent during the bending process, preventing the bending position from shifting and reducing the error in the bending position between sheets in the same batch, thus facilitating subsequent assembly.

Detailed Implementation

[0019] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1-4 As shown, this embodiment provides a sheet metal curvature bending device, including an operating table 10, a bending component 20, and a positioning component 30.

[0021] Specifically, such as Figure 1 As shown, the top surface of the operating table 10 has a rectangular structure for placing the board 1. The bottom of the operating table 10 has four vertically downward-facing support legs. Right-angle grooves 11 are provided on both sides of the top surface of the operating table 10, with their inner right angles facing upwards. The right-angle grooves 11 are arranged along the length of the operating table 10. Two strip-shaped holes 12 are symmetrically provided on the top surface of the operating table 10, and the strip-shaped holes 12 are located on the inner side of the vertical sidewall of the corresponding right-angle groove 11.

[0022] The bending component 20 is used to clamp one end of the plate 1 and bend the plate 1. The bending component 20 includes a clamping plate 21, a rotating rod 22, a motor 23, and a connecting seat 24. The motor 23 is located on one side of the operating table 10. A set of rotating rods 22 is provided, and one end of each rotating rod 22 is located in a corresponding right-angle slot 11. In the initial state, the length direction of the rotating rod 22 is consistent with the length direction of the operating table 10. One end of the rotating rod 22 is rotatably connected to the vertical side wall of the right-angle slot 11, and the other end extends out of one end of the operating table 10. One of the rotating rods 22 is connected to... One end of the right-angle groove 11 is fixedly connected to the output end of the motor 23. The connecting seat 24 is located at the end of the rotating rod 22 that extends out of the operating table 10. The connecting seat 24 has a T-shaped structure. Its vertical part is set horizontally and is rotatably connected to the end of the rotating rod 22 that extends out of the operating table 10. Its horizontal part faces the long axis of the operating table 10. A set of clamping plates 21 is provided. The length direction of the clamping plates 21 is set parallel to the width direction of the operating table 10. The clamping plates 21 can move relative to or away from each other along the horizontal part of the connecting seat to clamp one end of the plate 1 to be bent.

[0023] The positioning component 30 is used to determine the bending position of the plate 1. The positioning component 30 includes a cylinder 31, a vertical support 32, and a cylinder 33. The vertical support 32 is vertically inserted into the strip hole 12. The cylinder 33 is vertically installed at the bottom of the operating table 10, and its output end is vertically connected to the lower end of the vertical support 32. The cylinder 31 is located on the top surface of the operating table 10 along the width direction of the operating table 10. The upper end of the vertical support 32 is provided with a threaded hole, and a connecting bolt 321 is installed in the threaded hole. The connecting bolt 321 is threadedly connected to both ends of the cylinder 31, so that a detachable connection is formed between the vertical support 32 and the cylinder 31, so as to facilitate the replacement of the cylinder 31 and thus adapt to the size requirements of different bending curvatures of the plate 1.

[0024] The projection of the axis connecting the upper threaded holes of the two vertical supports 32 and the axis connecting the two rotating rods 22 and the right-angle groove 11 at the rotating connection point on the operating table 10 coincides with the projection of the axis connecting the upper threaded holes of the two vertical supports 32 and the axis connecting the two rotating rods 22 and the right-angle groove 11 on the operating table 10, so as to ensure that when the clamping plate 21 clamps one end of the plate 1 and bends it, the bending point of the plate 1 is concentric with the actual bending position.

[0025] Specific operating procedures: Keep the clamping plate 21 in such a position Figure 1 In the state shown, cylinder 33 is activated, causing it to push the vertical support 32 vertically upward to a certain height, so that the distance between the lower side of cylinder 31 and the top surface of operating table 10 is greater than the thickness of the plate 1 to be bent. Plate 1 is pushed into the operating table 10 from the end away from clamping plate 21, and one end of plate 1 is pushed into clamping plate 21. Cylinder 33 is activated again, causing it to drive the vertical support 32 to move vertically downward, so that cylinder 31 presses the top surface of plate 1. Then clamping plate 21 is activated, clamping one end of plate 1. Finally, motor 23 is activated, and motor 23 drives the corresponding rotating rod 22 to rotate upward by a predetermined angle, thereby achieving the bending of plate 1.

[0026] Preferably, the rotating rod 22 is configured as a telescopic structure to accommodate the distance between the bending position of different plates 1 and one end of the plate 1.

[0027] Preferably, in order to reduce the error between the bending positions of the same batch of boards, a baffle 211 is vertically provided in the middle of the starting clamping plate 21. When in use, the end of the board 1 that extends out of the operating table 10 abuts against the baffle 211, and the bottom surface of one end of the board 1 is supported by the clamping plate 21 located on the lower side, so that the board 1 remains flush with the top surface of the operating table 10 before bending.

[0028] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
