[0043] In order to more clearly understand the embodiments of the present application, the following Figures 1 to 8 The embodiments of the present application are described in detail.

[0044] like Figures 1 to 8 As shown, the present application provides a bending device 1 for bending a member 2 to be bent, the member 2 to be bent includes a main body 21 and a connecting part 22, and the bending device 1 includes: a movable member 11, a pressure member 13 and a fixed member 12. The movable member includes a moving part 111 and a rotating part 112, the moving part 11 can move along a first direction X, and the moving part 11 and the rotating part 12 can be rotatably connected; the pressure member 13 is arranged along the first direction X corresponding to the moving part 11, the main body 21 and the connecting part 22 are respectively arranged on the side of the moving part 111 and the rotating part 112 close to the pressure member 13; the fixed member 12 is arranged along the first direction X on the side of the rotating part 112 away from the pressure member 13.

[0045] The part to be bent 2 can be any part that needs to be bent, and its material can be metal, alloy, etc., and this application does not impose any restrictions on this. This application also does not impose any restrictions on the shape of the bending part 2. For example, in some embodiments, the bending part 2 can be a connecting piece in a battery, and the battery and an external electrical device or other batteries are connected through the connecting piece to output electrical energy or form a series-parallel circuit. The part to be bent 2 includes a main body 21 and a connecting part 22. For example, in some embodiments, the bending part 2 is a connecting piece in a battery, and the main body 21 in the bending part 2 is connected to the battery cell in the battery, and the connecting part 22 is connected to the output pole (positive or negative pole) of the battery to output the electrical energy in the battery cell to the positive and negative poles of the battery.

[0046] The movable member 11 includes a moving part 111 and a rotating part 112. When bending, the moving part 111 moves along the first direction X driven by the pressure member 13. The movement of the moving part 111 in the first direction X can be achieved by a slide rail or by a rack in a gear rack mechanism. The moving part 111 and the rotating part 112 are rotatably connected. In some embodiments, the relative rotation of the moving part 111 and the rotating part 112 can be achieved by a rotating shaft. 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 corresponding concave part is provided on the rotating part 112. The relative rotation of the moving part 111 and the rotating part 112 can be achieved by snapping the convex part and the concave part.

[0047] like Figures 6 to 8 As shown, as the moving distance of the moving part 111 along the first direction X increases, the larger the angle of rotation of the rotating part 112, the smaller the angle between the rotating part 112 and the moving part 111, and the smaller the bending angle of the to-be-bent part 2. Therefore, different bending angles of the to-be-bent part 2 can be achieved by controlling the moving distance of the moving part 111, and the bending angle is greater than or equal to 90° and less than 180°.

[0048] The pressure member 13 is disposed along the first direction X corresponding to the moving part 111 , and when bending, the pressure member 13 can apply pressure along the first direction X to the moving part 111 to drive the moving part 111 to move along the first direction X. In some embodiments, the pressure member 13 is also connected to a driving member such as an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder to provide a driving force for the pressure member 13 .

[0049] The main body 21 and the connecting part 22 are respectively arranged on the side of the moving part 111 and the rotating part 112 close to the pressure member 13, that is, the main body 21 is arranged on the side of the moving part 111 close to the pressure member 13 and the connecting part 22 is arranged on the side of the rotating part 112 close to the pressure member 13. The main body 21 is arranged on the side of the moving part 111 close to the pressure member 13, which will result in the main body 21 of the part 2 to be bent being fixed between the pressure member 13 and the positioning part 111 when the pressure member 13 moves along the first direction X during bending, thereby achieving the positioning of the part 2 to be bent. At the same time, the connecting part 22 is arranged on the side of the rotating part 112 close to the pressure member 13, and when the rotating part 112 rotates relative to the moving part 111, it will drive the connecting part 22 to rotate relative to the main body 21, thereby achieving the bending process of the part 2 to be bent.

[0050] The fixing member 12 refers to a component that is fixed relative to the movable member 11 during the bending process, and can be a component fixedly connected to the frame or a part of the frame. The fixing member 12 is arranged along the first direction X on the side of the rotating part 112 away from the pressure member 13, so when the moving part 111 moves along the first direction X, the fixing member 12 can constrain the movement of the rotating part 112 along the first direction X, so that the moving part 111 and the rotating part 112 can rotate relative to each other.

[0051] First, when bending, the pressure member 13 moves along the first direction X and applies pressure to the moving part 111, so that the main body 21 is fixed between the pressure member 13 and the moving part 111, thereby realizing the positioning of the part 2 to be bent in the bending device; second, because the distance that the moving part 111 moves along the first direction X directly determines the angle that the rotating part 112 rotates relative to the moving part 111 (that is, determines the angle between the main body 21 and the connecting part 22 in the bending part 2 after bending), the bending device 1 can realize bending of the part 2 to be bent at different angles, and has good compatibility. Third, the pressure member 13 continues to move along the first direction X, so that the moving part 111 moves along the first direction X, and the rotating part 112 rotates relative to the moving part 111 under the restriction of the fixing member 12, thereby causing the connecting part 22 placed on the rotating part 112 to rotate relative to the main body 21 and be bent. During the bending process, the connecting portion 22 of the part to be bent 2 is a free end, so that the connecting portion 22 of the part to be bent 2 can be extended during the bending process, thereby releasing stress, preventing the part to be bent 2 from cracking during the bending process, and improving the yield rate.

[0052] like Figure 3 and Figure 4 As shown, in some embodiments, the movable member 11 further includes a rotating shaft 113 , and the movable portion 111 and the rotating portion 112 are rotatably connected via the rotating shaft 113 .

[0053] The movable part 111 and the rotating part 112 are rotatably connected by the rotating shaft 113 , which has a simple structure and is easy to install and disassemble, thus facilitating daily maintenance and replacement of the bending device 1 .

[0054] like Figure 3 and Figure 4 As shown, in some embodiments, the movable member 11 further includes a torsion spring 114 , which is sleeved on the rotating shaft 113 , and at least one end of the torsion spring 114 is connected to the moving portion 111 and / or the rotating portion 112 .

[0055] At least one end of the torsion spring 114 is connected to the moving part 111 and / or the rotating part 112, which means that, in some embodiments, one end of the torsion spring 114 is connected to the moving part 111 or the rotating part 112, and in some embodiments, the two ends of the torsion spring 114 are respectively connected to the moving part 111 and the rotating part 112. The connection method of the end of the torsion spring 114 to the moving part 111 and / or the rotating part 112 can be a non-detachable method such as welding, or a detachable method such as clamping, which is not limited in the embodiments of the present application.

[0056] By providing the torsion spring 114, the movable part 111 moves along the first direction X during bending, causing the torsion spring 114 to deform and store energy. When the bending is completed and the pressure member 13 is removed, the bending spring will return to its initial shape and release the stored energy, driving the movable part 111 to return to its initial position.

[0057] like Figures 3 to 8 As shown, in some embodiments, the surface of the moving portion 111 close to the pressure member 13 is recessed along the first direction X to form a first receiving groove 1111 , and the main body 21 is received in the first receiving groove 1111 .

[0058] By providing the first receiving groove 1111 to receive the main body 21, the main body 21 can be positioned before bending to ensure the bending accuracy;

[0059] like Figures 3 to 8 As shown, in some embodiments, the first receiving groove 1111 is a recessed portion that gradually decreases along the first direction X.

[0060] The first receiving groove 1111 is a recessed portion that gradually decreases along the first direction X, that is, the first receiving groove 1111 is a groove with a gradually increasing opening, which can form an inclined guiding slope to guide the main body 21 into the first receiving groove 1111, thereby facilitating the positioning of the main body 21.

[0061] like Figures 3 to 8As shown, in some embodiments, the surface of the rotating portion 112 close to the pressure member 13 is recessed along the first direction X to form a second receiving groove 1121 , and the connecting portion 22 is received in the second receiving groove 1121 .

[0062] By providing a second accommodating groove 1121 to accommodate the connecting portion 22, on the one hand, the connecting portion 22 can be positioned before bending to ensure bending accuracy; on the other hand, during the bending process, the second accommodating groove 1121 can limit the connecting portion 22 to ensure that the connecting portion 22 will not deviate, thereby providing bending accuracy.

[0063] like Figures 3 to 8 As shown, in some embodiments, the second receiving groove 1121 is a recessed portion that gradually decreases along the first direction X.

[0064] The second receiving groove 1121 is a concave portion that gradually decreases along the first direction X, that is, the second receiving groove 1121 is a groove with a gradually increasing opening, which can form an inclined guiding slope to guide the connecting portion 22 into the second receiving groove 1121, so as to facilitate the positioning of the connecting portion 22.

[0065] like Figures 3 to 8 As shown, in some embodiments, the bottom surface of the first receiving groove 1111 and the bottom surface of the second receiving groove 1121 are on the same plane.

[0066] In some embodiments, in order to facilitate manufacturing and simplify the manufacturing process, the main body 21 and the connecting portion 22 of the part to be bent 2 are usually of the same thickness. At this time, the bottom surface of the first accommodating groove 1111 and the bottom surface of the second accommodating groove 1121 are in the same plane. On the one hand, it can ensure that when the main body 21 contacts the bottom surface of the first accommodating groove 1111, the connecting portion 22 can also contact the bottom surface of the second accommodating groove 1121, thereby ensuring the positioning accuracy of the part to be bent 2; on the other hand, it can prevent the part to be bent 2 from warping or shifting when the pressure-applying member 13 applies pressure to the moving portion 111 due to the fact that one of the bottom surfaces of the main body 21 and the first accommodating groove 1111 and the bottom surfaces of the connecting portion 22 and the second accommodating groove 1121 are not in contact, thereby affecting the positioning accuracy and bending quality of the part to be bent 2.

[0067] like Figures 6 to 8 As shown, in some embodiments, the surface of the fixing member 12 close to the moving portion 111 is the first surface 121 , and the surface of the fixing member 12 close to the rotating portion 112 is the second surface 122 , and there is an arc transition between the first surface 121 and the second surface 122 .

[0068] The arc transition between the first surface 121 and the second surface 122 can, on the one hand, ensure that the rotating part 112 slides smoothly from the first surface 121 to the second surface 122; on the other hand, setting the edge formed between the first surface 121 and the second surface 122 as an arc transition can not only reduce the stress concentration on the edge, prevent the edge from breaking and affecting the bending quality, but also reduce the force of the edge on the rotating part 112, preventing the rotating part 112 from being damaged due to excessive force.

[0069] like Figures 6 to 8 As shown, in some embodiments, the bending device 1 further includes a base 14 , which is spaced apart along the first direction X at a side of the movable member 11 away from the pressure member 13 , and an elastic member 15 is disposed between the base 14 and the movable member 11 .

[0070] The base 14 can be a part of the frame or a part fixedly connected to the frame. The shape of the base 14 is not limited, and the material of the base is not limited.

[0071] The elastic member 15 refers to a part made of elastic material, and the elastic member can be a spring or a part made of rubber material.

[0072] By arranging an elastic member 15 between the base 14 and the movable member 11, on the one hand, it can play a buffering role to prevent the pressure applied by the pressure member 13 from being too large and damaging the bending device 1. On the other hand, the compressed elastic member 15 can provide the movable member 11 with an elastic force that deviates from the first direction X, so that after the bending is completed, the movable member 11 can return to its initial position and prepare for the next bending.

[0073] like Figures 6 to 8 As shown, in some embodiments, the elastic member 15 is a spring, one end of the spring abuts against the base 14 , and the other end of the spring abuts against the movable member 11 .

[0074] Similarly, the spring can play a buffering role on the one hand, and can provide elastic force for the movable part 11 on the other hand to restore the movable part 11 to the initial position.

[0075] like Figures 1 to 8 In some embodiments shown, the bending device 1 further includes a guide 16 , and the guide rail 16 is arranged along the first direction X. One end of the guide rail 16 is fixedly connected to the base 14 , and the other end is slidably connected to the movable member 11 .

[0076] One end of the guide rail 16 is fixedly connected to the base 14. The so-called fixed connection means that there is no relative motion relationship between the guide rail 16 and the base 14. The fixed connection between the guide rail 16 and the base 14 can be achieved by non-detachable connections such as welding and riveting, or by detachable connections such as snap-on and bolt connections.

[0077] The other end of the guide rail 16 is slidably connected to the movable part 11. In some embodiments, a slider can be provided on the movable part 11, and the sliding connection between the guide rail 16 and the movable part 11 is achieved through the slider and the guide rail 16; in some embodiments, a through hole can be provided on the movable part 11, and the through hole is sleeved on the slide rail 16 to achieve the sliding connection between the guide rail 16 and the movable part 11.

[0078] The guide rail 16 can be cylindrical or square, which is not limited in the present application. The guide rail 16 is arranged along the first direction X, so that the movable member 11 can move along the first direction X under the constraint of the guide rail 16. In some embodiments, there are multiple guide rails 16, and multiple guide rails 16 can increase the constraint effect on the movable member 11 along the first direction X, thereby increasing the stability of the bending device 1.

[0079] In some embodiments, the elastic member 15 can be sleeved in the guide rail 16, and the movement of the elastic member 15 except along the first direction X can be limited to achieve the positioning of the elastic member 15. Of course, in some embodiments, grooves can also be provided on two opposite surfaces of the movable member 11 and / or the base 14, and at least one end of the elastic member 15 can be accommodated in the groove to achieve the positioning of the elastic member 15.

[0080] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the bending device 1 further includes a linear bearing 17 , and the movable member 11 is slidably connected to the guide rail 16 via the linear bearing 17 .

[0081] The linear bearing 17 has the characteristics of low friction and high stability. The sliding connection between the movable part 11 and the guide rail 16 is achieved through the linear bearing 17, which can ensure that the movable part 11 moves smoothly on the guide rail 16.

[0082] like Figure 3 and Figures 6 to 8 As shown, in some embodiments, the bending device 1 further includes a negative pressure member 18 , and the negative pressure member 18 is connected to a surface of the moving portion 111 close to the pressure member 13 .

[0083] The negative pressure member 18 is also an exhaust device. When the negative pressure member 18 is connected to the surface of the movable portion 111 close to the pressure member 13, a negative pressure environment can be formed on the surface of the movable portion 111 close to the pressure member 13 so that the main body 21 of the part to be bent 2 is adsorbed on the movable portion 111, thereby further improving the positioning accuracy of the part to be bent 2.

[0084] In some embodiments, the negative pressure member 18 may also be a vacuum device, so that a vacuum environment is formed on the surface of the movable portion 111 close to the pressure member 13, thereby improving the adsorption capacity of the negative pressure member 18 and enhancing the adsorption and fixing reliability of the main body 21 and the movable portion 111.

[0085] like Figures 6 to 8 As shown, in some embodiments, a communication channel 115 is further provided on the movable member 11 , one end of the communication channel 115 is connected to the negative pressure member 18 , and the other end is connected to the surface of the moving portion 111 close to the pressure member 13 .

[0086] The communication channel 115 can be a circular through hole or a square through hole, and the present application does not limit this. In some embodiments, there are multiple communication channels 115, and the multiple communication channels 115 are evenly distributed on the surface of the moving part 111 close to the pressure member 13, which can increase the adsorption capacity of the negative pressure member 18 on the one hand, and make the main body 21 evenly stressed on the other hand, avoiding damage to the main body 21.

[0087] By arranging the communication channel 115 on the movable member 11, the number of pipelines to be laid can be reduced, so that the volume and floor space of the bending device 1 are reduced.

[0088] like Figure 1 , Figure 4 and Figures 6 to 8 As shown, in some embodiments, the bending device 1 further includes a limiting member 19, and the limiting member 19 is used to limit the movement of the movable member 11 away from the first direction X.

[0089] like Figure 1 As shown, in some embodiments, the limiting member 19 includes a first limiting portion 191 and a second limiting portion 192, the first limiting portion 191 is fixedly connected to the movable member 11, and the first limiting member 191 has a first protrusion protruding toward the direction close to the limiting member 19; one end of the second limiting portion 192 is fixedly connected to the base 14, and the other end is provided with a second protrusion protruding toward the direction close to the movable member 11, the surface of the second protrusion facing away from the pressure member 13 abuts against the surface of the first protrusion close to the pressure member 13, so as to limit the movement of the movable member 111 along the direction X away from the first direction.

[0090] like Figure 4 and Figures 6 to 8 As shown, in some embodiments, the limit member 19 is a stop block, which is fixed to the end of the guide rail 16 away from the base 14, and abuts against the linear bearing 17 and / or the side of the movable member 11 close to the pressure member 13, thereby limiting the movement of the movable member 111 away from the first direction X.

[0091] It should be noted that the above two methods for limiting the movement of the movable member 111 in the direction away from the first direction X can be used simultaneously or separately, and the present application does not limit this.

[0092] like Figure 4 and Figures 6 to 8As shown, in some embodiments, the movable member 11 further includes a mounting portion 116 , the mounting portion 116 is provided with an avoidance hole 117 , and the fixing member 12 is disposed in the avoidance hole 117 .

[0093] By providing the avoidance hole 117 , the movable member 11 can move along the first direction X without being blocked by the fixed member 12 .

[0094] In some embodiments, the guide rail 16 may be disposed on the mounting portion 113 .

[0095] like Figure 1 As shown, the present application provides a floating bending device on the other hand, which includes a bending device 1 and a floating device 3 , and the floating device 3 is connected to a pressure member 13 .

[0096] 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 to the pressure member 13, and the pressure member 13 can float in any direction in a plane perpendicular to the first direction X during the bending process, so as to realize the relative position alignment of the pressure member 13 and the movable member 11, thereby improving the bending accuracy of the bending device 1.

[0097] The above-mentioned bending device 1 and floating bending equipment, firstly, when bending, the pressure member 13 moves along the first direction X and applies pressure to the moving part 111, so that the main body 21 is fixed between the pressure member 13 and the moving part 111, thereby realizing the positioning of the part 2 to be bent in the bending device; secondly, because the distance that the moving part 111 moves along the first direction X directly determines the angle that the rotating part 112 rotates relative to the moving part 111 (that is, determines the angle between the main body 21 and the connecting part 22 in the bending part 2 after bending), the bending device 1 can realize bending of different angles of the part 2 to be bent, and has good compatibility. Thirdly, the pressure member 13 continues to move along the first direction X, so that the moving part 111 moves along the first direction X, and the rotating part 112 rotates relative to the moving part 111 under the restriction of the fixing member 12, thereby causing the connecting part 22 placed on the rotating part 112 to rotate relative to the main body 21 and be bent. During the bending process, the connecting portion 22 of the part to be bent 2 is a free end, so that the connecting portion 22 of the part to be bent 2 can be extended during the bending process, thereby releasing stress, preventing the part to be bent 2 from cracking during the bending process, and improving the yield rate.

[0098] Specifically, Figures 1 to 8As shown, when loading, the pressure member 13 and the movable member are in a separated state, and the movable member 11 is in the initial position under the constraint of the elastic member 15 and the limit 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 in the same plane, and the part 1 to be bent is loaded into the bending device 1, and the part 2 to be bent falls into the accommodating groove so that the main body 21 is accommodated in the first accommodating groove 1111, and the connecting part 22 is accommodated in the second accommodating groove 112, completing the pre-positioning of the part 2 to be bent; then start the negative pressure member 18 to adsorb and fix the part 2 to be bent in the bending device 1.

[0099] During operation, the pressure member 13 moves along the first direction X and approaches the movable member 11, and applies pressure along the first direction X to the movable member 11, while clamping the main body 21 of the member 2 to be bent between the pressure member 13 and the movable portion 111. The pressure member 13 continues to move along the first direction X, so that the main body 21 and the movable portion 111 move along the first direction X together, and the connecting portion 22 is bent under the restriction of the fixing member 12 until the member 2 to be bent is bent to a predetermined angle, and the pressure member 13 stops moving. Then the pressure member 13 moves away from the first direction X, gradually removing the pressure applied to the movable member 11, and at the same time, the movable member 11 also moves away from the first direction X driven by the elastic force provided by the elastic member 15 and the torsion spring 114, and finally stops moving under the restriction of the limit member 19 and returns to the initial position.

[0100] When unloading, the negative pressure member 18 stops working, and the negative pressure environment formed on the surface of the moving portion 111 close to the pressure member 13 disappears, so that the bent workpiece 2 can be easily removed.

[0101] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0102] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
