[0027] Reference Figures 1 to 5, an embodiment of the present application provides a sheet metal bending device, which includes a mounting base 1, a rotating part 2, a pressing rod 3, two sets of driving components and an adjusting component. The mounting base 1 has a first seat surface and a second seat surface oppositely arranged in a first direction, and the first direction is the same as the thickness direction of the mounting base 1; the rotating part 2 is rotatably connected to a side of the mounting base 1 and has a degree of freedom of rotating around a second direction, and the second direction is perpendicular to the first direction; the pressing rod 3 is arranged on the side of the first seat surface facing away from the second seat surface and extends along the second direction. Among them, in a third direction, the side of the pressing rod 3 close to the rotating part 2 and the side of the mounting base 1 close to the rotating part 2 are in the same plane, and the third direction is perpendicular to the first direction and the second direction respectively; the two sets of driving components are oppositely arranged at both ends of the pressing rod 3 in the second direction and are connected to the mounting base 1, and the driving components provide a driving force for the pressing rod 3 to move along the first direction, so as to clamp the sheet metal 7 to be bent through the pressing rod 3 and the mounting base 1; the adjusting component is arranged on the side of the first seat surface facing away from the second seat surface and has a degree of freedom of moving along the third direction. Among them, the adjusting component extends or retracts along the third direction in response to the transmission force from the side of the mounting base 1 connected to the rotating part 2.
[0028] For a sheet metal bending device proposed in an embodiment of the present application, the adjusting driving component controls the pressing rod 3 to move away from the mounting base 1 in the first direction, inserts the sheet metal 7 to be bent into the gap between the pressing rod 3 and the mounting base 1, and then the adjusting driving component controls the pressing rod 3 to move close to the mounting base 1 in the first direction to clamp and fix the sheet metal 7 to be bent; then control the length of the adjusting component extending out of the mounting base 1, and rotate the rotating part 2 until the rotating part 2 abuts against the adjusting component, then the bending can be completed, and the angle of the sheet metal bending changes with the length of the adjusting component extending out of the mounting base 1, which is convenient for accurately controlling the bending angle of the sheet metal and makes the use more convenient.
[0029] Specifically, as Figure 1 shown, the first direction is the X direction, the second direction is the Y direction, and the third direction is the Z direction. Taking the mounting base 1 as a reference, the first direction X is the thickness direction of the mounting base 1, the second direction Y is the length direction of the mounting base 1, and the third direction Z is the width direction of the mounting base 1.
[0030] It should be noted that the included angle at the bent part of the sheet metal is a. As Figure 1 shown, the longer the length of the adjusting component extending out of the mounting base 1, the larger the value of a; when the adjusting component does not extend out of the mounting base 1, a = 90°.
[0031] Furthermore, as Figure 1 shown, a grip rod is arranged on the side of the rotating part 2 facing away from the mounting base 1. It is more convenient to drive the rotation of the rotating part 2 through the grip rod, and the distance from the force application point to the rotation area is farther, so it is more labor-saving to rotate the rotating part 2 to bend the sheet metal.
[0032] Among them, as Figure 1As shown, a plurality of support legs are provided on the side of the second seat surface facing away from the first seat surface. The support legs support the mounting seat 1. When the iron sheet bending device is in use, the first direction X can be the direction of gravity.
[0033] It should be understood that when bending, the rotating part 2 rotates towards the side of the first seat surface facing away from the second seat surface.
[0034] Reference Figure 4 , in an exemplary embodiment, the driving assembly may include a first support block 41 and a first threaded rod 42. The first support block 41 is fixed to one end of the extrusion rod 3; the first threaded rod 42 is rotatably connected to the mounting seat 1 and has the freedom to rotate about its own axis. The axis of the first threaded rod 42 is the same as the first direction X and penetrates through the first support block 41. The first threaded rod 42 is threadedly connected to the first support block 41.
[0035] Specifically, if there are two sets of driving assemblies, then there are two first threaded rods 42. In this way, both ends of the extrusion rod 3 are respectively connected to a first threaded rod 42. The extrusion rod 3 cannot rotate about the first direction X. When the two first threaded rods 42 are rotated, the extrusion rod 3 can be driven by the first support block 41 to move along the first direction X, so as to clamp or loosen the iron sheet 7 to be bent.
[0036] Furthermore, the driving assembly may further include a spring 43. The spring 43 is sleeved on the outer periphery of the first threaded rod 42 and its two ends are respectively connected to the first support block 41 and the mounting seat 1. In this way, when the first threaded rod 42 is rotated to drive the first support block 41 away from the mounting seat 1, the spring 43 applies a force to the first support block 41 to move away from the mounting seat 1, without the need to overcome the gravity of the extrusion rod 3 through the first threaded rod 42 to drive the extrusion rod 3 away from the mounting seat 1, which is more labor-saving.
[0037] Reference Figure 5 , in an exemplary embodiment, the adjusting assembly may include a second support block 51 and a second threaded rod 52. The second support block 51 is fixed to the mounting seat 1; the second threaded rod 52 penetrates through the second support block 51 and is threadedly connected to the second support block 51. The axis of the second threaded rod 52 is the same as the third direction Z and has the freedom to rotate about its own axis; wherein, one end of the second threaded rod 52 extends or retracts along the third direction Z from the side of the mounting seat 1 connected to the rotating part 2 in response to the driving force.
[0038] Specifically, since the second threaded rod 52 is threadedly connected to the second support block 51, the length of the second threaded rod 52 extending out of the mounting seat 1 can be controlled by rotating the second threaded rod 52, and thus the bending angle of the iron sheet can be controlled.
[0039] Furthermore, the adjustment assembly may also include a rotating section 53 and a contact block 54, wherein the rotating section 53 is rotationally connected to one end of the second threaded rod 52 close to the rotating part 2 and has the freedom to rotate around the axial direction of the second threaded rod 52; the contact block 54 is rotationally connected to one end of the rotating section 53 away from the second threaded rod 52 and has the freedom to rotate around the second direction Y.
[0040] Among them, the contact block 54 can move in the third direction Z following the second threaded rod 52, and the position of the contact block 54 extending out of the mounting seat 1 can be controlled to make the rotating part 2 contact with the contact block 54 to adjust the bending angle of the iron sheet. Compared with the contact between the rotating part 2 and the second threaded rod 52, the contact area between the rotating part 2 and the contact block 54 is greatly increased, and the pressure applied to the rotating part 2 is smaller. When the force applied to rotate the rotating part 2 to bend the iron sheet is large, it is effectively prevented that the rotating part 2 is damaged by the large pressure caused by the collision with the second threaded rod 52.
[0041] Furthermore, the contact block 54 can rotate around the second direction Y, so that the contact block 54 can fit with the rotating part 2 to ensure that the area of the interference region does not change due to the different positions of the contact block 54.
[0042] The rotating section 53 can rotate around the axial direction of the second threaded rod 52, so that the contact block 54 will not be driven to rotate synchronously when the second threaded rod 52 is rotated, ensuring that the contact block 54 can always rotate around the second direction Y.
[0043] like Figure 5 As shown, the rotating section 53 and the contact block 54 are clearance-fitted and the fitting area is close to the side of the contact block 54 away from the mounting seat 1, so that the contact block 54 always sags due to gravity. Therefore, when the second threaded rod 52 rotates, even if it drives the contact block 54 to rotate, the second contact block 54 will also drive the rotating section 53 to rotate around the axial direction of the second threaded rod 52 due to its own gravity, so that the contact block 54 rotates back to its original position.
[0044] refer to Figure 5 In an exemplary embodiment, the side of the contact block 54 facing away from the rotating section 53 is connected to the side of the contact block 54 close to the mounting seat 1 through an arc surface structure, so that when the rotating part 2 contacts the contact block 54, it will first contact the arc surface structure and further push the contact block 54 to rotate around the second direction Y until it fits with the rotating part 2, and the rotation process of the contact block 54 is more stable.
[0045] refer to Figure 2, in an exemplary embodiment, a plurality of limiting grooves 21 with a depth direction the same as the third direction Z are provided on one side of the mounting base 1 facing the rotating part 2, and the limiting grooves 21 are spaced apart in the second direction Y; the iron sheet bending device may further include a plurality of moving rods 61 and a baffle 62, and the plurality of moving rods 61 are respectively inserted into the plurality of limiting grooves 21; the baffle 62 is arranged at one end of each moving rod 61 outside the corresponding limiting groove 21; wherein, the iron sheet 7 to be bent has a projection on the baffle 62 along the third direction Z; a through groove for the moving rod 61 to pass through is formed on the rotating part 2.
[0046] Specifically, when pulling the baffle 62 along the third direction Z, the moving rod 61 slides in the corresponding limiting groove 21 to adjust the position of the baffle 62 in the third direction Z, so that the iron sheet 7 to be bent abuts against the baffle 62. In this way, the bending position of the iron sheet 7 to be bent in the third direction Z can be controlled, making it more convenient to use.
[0047] As Figure 2 shown, a through groove for the moving rod 61 to pass through is formed on the rotating part 2 to ensure that the rotating part 2 does not affect the movement of the baffle 62.
[0048] Furthermore, the iron sheet 7 to be bent has a projection on the baffle 62 along the third direction Z, ensuring that the iron sheet 7 to be bent can abut against the baffle 62 when it is clamped between the pressing rod 3 and the mounting base 1.
[0049] Refer to Figure 2 , in an exemplary embodiment, a moving rod 61 and the corresponding limiting groove 21 are both elliptical. The cross-section of the elliptical moving rod 61 perpendicular to the third direction Z is a first ellipse, and the cross-section of the corresponding limiting groove 21 perpendicular to the third direction Z is a second ellipse; the major axis length of the first ellipse is greater than the minor axis length of the second ellipse; the elliptical moving rod 61 is rotatably connected to the baffle 62 and has a degree of freedom of rotating around its own axis.
[0050] Specifically, when the baffle 62 moves to the target position, rotate the elliptical moving rod 61 so that the outer periphery of this moving rod 61 is pressed against the inner wall of the corresponding limiting groove 21, thereby fixing the position of this moving rod 61 and further fixing the position of the baffle 62. When it is necessary to move the baffle 62 again, just rotate the elliptical moving rod 61.
[0051] It should be noted that the major axis length of the first ellipse is greater than the minor axis length of the second ellipse, which can ensure that when the elliptical moving rod 61 is rotated, the outer periphery of this moving rod 61 can be pressed against the inner wall of the corresponding limiting groove 21.
[0052] Refer to Figure 3, in an exemplary embodiment, a connection hole extending along the third direction Z is provided on the baffle 62. The iron sheet bending device may further include a bearing 81 and a connection ring 82. The bearing 81 is disposed on the inner circumference of the connection hole and has the same axial direction as the third direction Z; the connection ring 82 is disposed on the inner circumference of the bearing 81 and sleeved on the outer circumference of the elliptical moving rod 61.
[0053] As Figure 3 shown, when the elliptical moving rod 61 rotates, it drives the connection ring 82 to rotate. The connection ring 82 realizes relative rotation with the baffle 62 through the bearing 81, and finally realizes the rotation of the elliptical moving rod 61 around its own axis.
[0054] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, can similarly be included in the patent protection scope of the present application.
