In order to more clearly understand the embodiments of the present application, the embodiments of the present application will be described in detail with reference to fig. 1 to 8.

As shown in fig. 1 to 8, the present application provides a bending apparatus 1 for bending a member to be bent 2, the member to be bent 2 including a body portion 21 and a connecting portion 22, and the bending apparatus 1 including a movable member 11, a pressing member 13 and a fixed member 12. The movable part comprises a moving part 111 and a rotating part 112, the moving part 11 can move along a first direction X, the moving part 11 and the rotating part 12 are rotatably connected, the pressing part 13 is arranged corresponding to the moving part 11 along the first direction X, the body part 21 and the connecting part 22 are respectively arranged on one side of the moving part 111 and one side of the rotating part 112, which are close to the pressing part 13, and the fixed part 12 is arranged on one side of the rotating part 112, which is away from the pressing part 13, along the first direction X.

The piece to be bent 2 may be any piece to be bent, and the material may be metal, alloy, etc., which is not limited in the present application. The shape of the bending member 2 is not limited in the present application. For example, in some embodiments the bending member 2 may be a connection tab in the battery, through which the battery is connected to an external power device or other battery to output electrical power or form a series-parallel circuit. The member to be bent 2 includes a body portion 21 and a connecting portion 22. For example, in some embodiments, the bending member 2 is a connecting piece in the battery, the body portion 21 in the bending member 2 communicates with the cell in the battery, and the connecting portion 22 communicates with the output electrode (positive electrode or negative electrode) of the battery to output the electric energy in the cell to the positive electrode or the negative electrode of the battery.

The movable member 11 includes a moving portion 111 and a rotating portion 112. The moving part 111 is moved in the first direction X by the pressing member 13 at the time of bending, and the movement of the moving part 111 in the first direction X may be realized by a slide rail or by a rack in a rack-and-pinion mechanism. The rotatable connection between the moving part 111 and the rotating part 112 may in some embodiments be achieved by a rotation shaft to achieve a relative rotation of the moving part 111 and the rotating part 112. In some embodiments, the relative rotation of the moving part 111 and the rotating part 112 is also achieved by a snap connection, for example, a convex part is provided on the moving part 111 and a concave part is provided on the rotating part 112 correspondingly, and the relative rotation of the moving part 111 and the rotating part 112 can be achieved by the snap connection of the convex part and the concave part.

As shown in fig. 6 to 8, as the moving distance of the moving portion 111 in the first direction X increases, the larger the angle through which the rotating portion 112 rotates, the smaller the angle between the rotating portion 112 and the moving portion 111, and the smaller the angle at which the bending member 2 is to be bent. Therefore, it is possible to realize different bending angles of the member to be bent 2, which are 90 ° or more and 180 ° or less, by controlling the moving distance of the moving portion 111.

The pressing piece 13 is disposed corresponding to the moving portion 111 along the first direction X, and the pressing piece 13 may apply a pressure along the first direction X to the moving portion 111 when bending, so as to drive the moving portion 111 to move along the first direction X. In some embodiments, the pressure applying member 13 is also in driving connection with a driving member such as an electric cylinder, an air cylinder, a hydraulic cylinder, or the like to provide driving force to the pressure applying member 13.

The body portion 21 and the connecting portion 22 are respectively disposed on the sides of the moving portion 111 and the rotating portion 112 near the pressing member 13, that is, the body portion 21 is disposed on the side of the moving portion 111 near the pressing member 13 while the connecting portion 22 is disposed on the side of the rotating portion 112 near the pressing member 13. The positioning of the to-be-bent member 2 is achieved by fixing the body portion 21 of the to-be-bent member 2 between the pressing member 13 and the positioning 111 when the pressing member 13 moves in the first direction X at the time of bending due to the body portion 21 being disposed on the side of the moving portion 111 near the pressing member 13. Meanwhile, the connecting portion 22 is disposed on a side of the rotating portion 112 near the pressing member 13, and when the rotating portion 112 rotates relative to the moving portion 111, the connecting portion 22 is driven to rotate relative to the body portion 21, so as to realize bending of the to-be-bent member 2.

The fixing member 12 is a member that is fixed relative to the movable member 11 during bending, and may be a member that is fixedly connected to the frame or may be a part of the frame. The fixing member 12 is disposed on a side of the rotating portion 112 away from the pressing member 13 along the first direction X, so that the moving portion 111 moves along the first direction X, and the fixing member 12 can restrict the moving portion 112 from moving along the first direction X, so that the moving portion 111 and the rotating portion 112 rotate relatively.

Firstly, the pressing member 13 moves along the first direction X and applies pressure to the moving portion 111 during bending, so that the body portion 21 is fixed between the pressing member 13 and the moving portion 111, and positioning of the to-be-bent piece 2 in the bending device is achieved, secondly, because the distance of the moving portion 111 moving along the first direction X directly determines the rotating angle of the rotating portion 112 relative to the moving portion 111 (that is, determines the angle after bending between the body portion 21 and the connecting portion 22 in the to-be-bent piece 2), bending of different angles of the to-be-bent piece 2 can be achieved through the bending device 1, and compatibility is good. Third, the pressing member 13 continues to move in the first direction X, so that the moving portion 111 moves in the first direction X, and the rotating portion 112 rotates relative to the moving portion 111 under the restriction of the fixing member 12, thereby causing the connecting portion 22 disposed on the rotating portion 112 to rotate relative to the main body portion 21 to be bent. In the bending process, the connecting part 22 of the piece to be bent 2 is a free end, so that the connecting part 22 of the piece to be bent 2 can be stretched in the bending process, thereby releasing stress, preventing the piece to be bent 2 from generating cracks in the bending process, and improving the yield.

As shown in fig. 3 and 4, in some embodiments, the movable member 11 further includes a rotating shaft 113, and the moving portion 111 and the rotating portion 112 are rotatably connected through the rotating shaft 113.

The end portion of the torsion spring 114 may be connected to the moving portion 111 and/or the rotating portion 112 by a non-detachable manner such as welding or by a detachable manner such as a clamping connection, which is not limited in the embodiment of the present application.

By providing the torsion spring 114, the moving portion 111 moves along the first direction X during bending to deform the torsion spring 114 to store energy, and when the pressing member 13 is removed after bending is completed, the bending spring returns to the original shape to release the stored energy, so as to drive the moving portion 111 to return to the original position.

As shown in fig. 1, in another aspect, the present application provides a floating bending apparatus, which includes a bending device 1 and a floating device 3, the floating device 3 being connected to a pressing member 13.

The floating device 3 refers to a device that can realize movement in any direction in a plane perpendicular to the first direction X. The floating device 3 is connected with the pressing piece 13, and the pressing piece 13 can be floated in any direction in a plane perpendicular to the first direction X in the bending process, so that the alignment of the relative positions of the pressing piece 13 and the movable piece 11 is realized, and the bending precision of the bending device 1 is improved.

The bending device 1 and the floating bending apparatus described above, firstly, the pressing member 13 moves along the first direction X during bending to apply pressure to the moving portion 111, so that the body portion 21 is fixed between the pressing member 13 and the moving portion 111, thereby realizing positioning of the to-be-bent member 2 in the bending device, secondly, because the distance that the moving portion 111 moves along the first direction X directly determines the angle by which the rotating portion 112 rotates relative to the moving portion 111 (i.e., the angle after bending between the body portion 21 and the connecting portion 22 in the to-be-bent member 2) is determined, bending of different angles of the to-be-bent member 2 can be realized through the bending device 1, and compatibility is good. Third, the pressing member 13 continues to move in the first direction X, so that the moving portion 111 moves in the first direction X, and the rotating portion 112 rotates relative to the moving portion 111 under the restriction of the fixing member 12, thereby causing the connecting portion 22 disposed on the rotating portion 112 to rotate relative to the main body portion 21 to be bent. In the bending process, the connecting part 22 of the piece to be bent 2 is a free end, so that the connecting part 22 of the piece to be bent 2 can be stretched in the bending process, thereby releasing stress, preventing the piece to be bent 2 from generating cracks in the bending process, and improving the yield.

Specifically, as shown in fig. 1 to 8, during feeding, the pressing member 13 and the movable member are in a separated state, the movable member 11 is located at an initial position under the constraint of the elastic member 15 and the limiting member 19, at this time, the bottom surface of the first accommodating groove 1111 and the bottom surface of the second accommodating groove 1121 are located at the same plane, the member 1 to be bent is fed into the bending device 1, the member 2 to be bent falls into the accommodating groove to enable the body portion 21 to be accommodated in the first accommodating groove 1111, the connecting portion 22 is accommodated in the second accommodating groove 112, the pre-positioning of the member 2 to be bent is completed, and then the negative pressing member 18 is started to enable the member 2 to be bent to be adsorbed and fixed in the bending device 1.

In operation, the pressing member 13 moves in the first direction X to approach the movable member 11, and applies pressure in the first direction X to the movable member 11 while sandwiching the body portion 21 of the member to be bent 2 between the pressing member 13 and the moving portion 111. The pressing member 13 continues to move in the first direction X, so that the body portion 21 moves in the first direction X together with the moving portion 111, and the connecting portion 22 is bent under the restriction of the fixing member 12 until the member to be bent 2 is bent to a predetermined angle, and the pressing member 13 stops moving. Then, the pressing member 13 moves in the direction away from the first direction X, the pressure applied to the movable member 11 is gradually removed, and at the same time, the movable member 11 is also driven by the elastic force provided by the elastic member 15 and the torsion spring 114 to move in the direction away from the first direction X, and finally stops moving under the limit of the limit member 19 to restore to the initial position.

When the material is discharged, the negative pressure piece 18 stops working, and the negative pressure environment formed on the surface of the moving part 111, which is close to the pressing piece 13, disappears, so that the folded piece 2 to be folded can be easily removed.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
