[0038] The following is combined with Figure 2-9 This application is described in further detail. Example

[0039] The present application embodiment discloses a bending device. Figure 2 and Figure 3 The bending device includes a base 2, a positioning member 3 installed on the base 2, and a bending member 4 installed on the side wall of the base 2. The composite busbar 1 is placed on the base 2, positioned by the positioning member 3, and then the bending member 4 bends the composite busbar 1.

[0040] Reference Figure 3 and Figure 4Two arc tracks 5 are installed on the side wall of the base 2. The arc tracks 5 are nearly a quarter arc structure. The arc mouth of the arc track 5 faces upward, and the center of the arc track 5 is higher than the upper surface of the base 2 and close to the adjacent long side of the base 2. The bending member 4 includes a bending plate 41 slidably installed between the two arc tracks 5. When the composite busbar 1 is placed on the base 2, the part to be bent extends above the arc track 5. When the bending plate 41 is in a horizontal state on the arc track 5, the composite busbar 1 is located below the bending plate 41. When the bending plate 41 slides downward along the circumference of the arc track 5, the bending plate 41 can bend the part of the composite busbar 1 located above the arc track 5.

[0041] Reference Figure 4 and Figure 5 The bending member 4 also includes a positioning plate 42 slidably disposed on the lower surface of the bending plate 41, and an elastic member 43 connected between the positioning plate 42 and the bending plate 41. The positioning plate 42 slides in a direction close to the base 2, and an extension bar 6 is fixed on the positioning plate 42, and the extension bar 6 extends in a direction away from the bending plate 41, and a contact angle is formed between the positioning plate 42 and the extension bar 6. When the bending plate 41 is in a horizontal state, the positioning plate 42 is located on the lower surface of the bending plate 41, and the extension bar 6 abuts against the part to be bent of the composite busbar 1, and under the action of the elastic member 43, the composite busbar 1 is always abutted against the extension bar 6. Therefore, during the movement of the bending plate 41, the positioning plate 42 bends the composite busbar 1, and there is almost no relative offset between the positioning plate 42 and the composite busbar 1, thereby reducing the scratches on the surface of the composite busbar 1.

[0042] Reference Figure 5 The lower surface of the bending plate 41 is provided with a sliding groove 22, and a plurality of sliding grooves 22 are provided, and the cross section of the sliding groove 22 is a dovetail structure. The side wall of the positioning plate 42 is fixed with a limit block 23 adapted to the sliding groove 22, so as to realize the sliding of the positioning plate 42. The elastic member 43 is a spring and is installed in the sliding groove 22, with one end connected to the limit block 23 and the other end connected to the inner end surface of the sliding groove 22.

[0043] Reference Figure 4 and Figure 5Sliding blocks 8 are fixed on both sides of the bending plate 41. The sliding blocks 8 are adapted to the shape of the arc track 5 and can slide in the arc track 5, thereby achieving the effect of the bending plate 41 sliding on the arc track 5. A reset member 9 is also installed in the arc track 5. The reset member 9 is preferably an arc spring, one end of which is connected to the lowermost end of the arc track 5, and the other end is connected to the side wall of the sliding block 8. Under the elastic force of the arc spring, the bending plate 41 can be kept in a horizontal state. When the bending plate 41 moves downward, the arc spring is compressed and provides a force to reset the sliding block 8. Preferably, the arc track 5 can be provided with a constricted structure, and the sliding block 8 and the arc track 5 are adapted to each other, thereby limiting the situation where the arc spring pops out.

[0044] Reference Figure 4 and Figure 6 , two vertical rods 10 are vertically fixed on the surface of the base 2, and the two vertical rods 10 are respectively located at the two ends of the base 2. The positioning member 3 includes a sliding rod 31 and a positioning rod 32, and the vertical rod 10 passes through the two ends of the sliding rod 31 and the positioning rod 32 respectively, so that the sliding rod 31 and the positioning rod 32 can slide in the vertical direction. The positioning rod 32 is located below the sliding rod 31, and a first elastic member 33 is arranged between the positioning rod 32 and the sliding rod 31, and a second elastic member 34 is arranged between the outer wall of the vertical rod 10 and the sliding rod 31. A guide rod 12 is arranged on the lower surface of the sliding rod 31, and a guide sleeve 11 is arranged on the upper surface of the positioning rod 32, and the guide rod 12 is slidably inserted in the guide sleeve 11. The first elastic member 33 is a spring installed in the guide sleeve 11. The second elastic member 34 is a spring sleeved on the outer wall of the vertical rod 10, and the second elastic member 34 is located above the positioning rod 32, and one end of the second elastic member 34 is connected to the lower surface of the sliding rod 31, and the other end is connected to the side wall of the vertical rod 10. A driving assembly 13 is also installed on the base 2. The driving assembly 13 can drive the sliding rod 31 to slide downward, the second elastic member 34 is compressed, and the positioning rod 32 slides downward and presses against the upper surface of the base 2, and the first elastic member 33 is compressed.

[0045] Reference Figure 3 and Figure 4The driving assembly 13 includes a rotating disk 131 rotatably mounted on both sides of the base 2 and a driving rod 132 slidably mounted on the rotating disk 131. The lower part of the base 2 is a hollow structure, and the rotating disk 131 is coaxially fixedly connected with a rotating shaft, and the rotating shaft is rotatably connected to the base 2 through bearings and other means, thereby completing the rotation connection of the rotating disk 131. A driving source 133 is also installed on the base 2, and the driving source 133 corresponds to the rotating disk 131, and the driving source 133 is used to drive the rotating disk 131 to rotate. The driving source 133 includes a driving gear 1331 rotatably mounted on the surface of the base 2, and the side walls of the rotating disk 131 are evenly set as tooth-like structures, and can mesh with the driving gear 1331. A first element 1332 is also installed on the inner wall of the base 2, and the first element 1332 is preferably a motor, and the output shaft is connected to the driving gear 1331, thereby driving the driving gear 1331 to rotate.

[0046] Combination Figure 7 A limiting groove 24 is provided on the side of the rotating disk 131 away from the base 2. The limiting groove 24 extends in the radial direction of the rotating disk 131. The driving rod 132 is slidably installed in the limiting groove 24. The cross section of the limiting groove 24 can be a dovetail structure, so that the driving rod 132 is not easy to escape from the limiting groove 24. A power source 14 for driving the driving rod 132 to slide is installed on the rotating disk 131. The power source 14 is preferably a cylinder, or a telescopic cylinder, a lead screw, etc. In this embodiment, a cylinder is taken as an example. The piston rod of the cylinder is connected to the driving rod 132 through a block, so as to realize the sliding of the driving rod 132.

[0047] Reference Figure 4 and Figure 8 , a resistance bar 15 is provided on the opposite side of the two driving rods 132. When the driving rod 132 is in a vertical state, the resistance bar 15 is located above the sliding rod 31, and the power source 14 drives the driving rod 132 to slide downward. The resistance bar 15 can drive the sliding rod 31 to slide downward, and drive the positioning rod 32 to press against the surface of the composite busbar 1. A clearance groove 16 is provided on the opposite side of the rotating disk 131, and the clearance groove 16 extends in the radial direction of the rotating disk 131. The ends of the sliding rod 31 and the positioning rod 32 both extend into the clearance groove 16. The side walls of the clearance groove 16 are respectively provided with a first groove body 17 and a second groove body 18, and the first groove body 17 and the second groove body 18 both extend in the circumferential direction of the rotating disk 131. Combined with Fig. 9When the contact bar 15 drives the sliding rod 31 and the positioning rod 32 to slide downward to a predetermined displacement, the rotating disk 131 rotates to allow the end of the sliding rod 31 to enter the first slot 17, and the end of the positioning rod 32 to enter the second slot 18. Under the limiting effect of the first slot 17 and the second slot 18, the rotating disk 131 can rotate and maintain the positioning effect on the composite busbar 1. When the rotating disk 131 starts to rotate, the power source 14 drives the driving rod 132 to reset, and the rotating disk 131 continues to rotate. The end of the driving rod 132 can cooperate with the sliding block 8 to drive the sliding block 8 to slide in the arc track 5, thereby bending the composite busbar 1.

[0048] Reference Fig. 9 The side of the arc track 5 away from the bending plate 41 is a hollow structure, and a boss 19 is fixed on the sliding block 8, and the boss 19 extends from the hollow part. When the rotating disk 131 rotates, the driving rod 132 can abut against the side wall of the boss 19 and push the sliding block 8 to slide on the arc track 5. In other embodiments, the boss 19 can be rotatably installed on the sliding block 8, so that the driving rod 132 can more easily push the sliding block 8 to slide.

[0049] Reference Fig. 9 , the bending part of some composite busbars 1 needs to be close to 90 degrees, and it is not easy to bend the bending part to the ideal angle through the bending plate 41 in this application. Therefore, the positioning plate 42 in this application is provided with extension rods 20 on both sides, and the extension rods 20 exceed the surfaces on both sides of the bending plate 41, and there is a certain gap between the extension rods 20 and the driving rod 132, which does not affect the driving rod 132 from abutting against the boss 19 to drive the sliding block 8 to slide. A resistance block 21 is fixed on the opposite side of the driving rod 132. After the bending plate 41 bends the composite busbar 1, the bending plate 41 is reset to a horizontal state, and the driving rod 132 rotates to a position close to the boss 19. Then, the driving rod 132 is driven by the power source 14 to slide in the direction close to the base 2, and the resistance block 21 can abut against the extension rod 20, and drive the positioning plate 42 to slide, so that the extension bar 6 can abut against the bending part of the composite busbar 1, and the bending angle of the bending part is bent to close to 90 degrees.

[0050] The side wall of the abutment bar 15 has an inclined surface, and during the sliding of the driving rod 132, the abutment bar 15 can abut against the end of the positioning rod 32 and drive the positioning rod 32 to slide upward, thereby providing space for the positioning plate 42 to slide. The side wall of the second trough body 18 is provided with a slot 25, and the end of the positioning rod 32 can move upward and enter the slot 25. After the positioning rod 32 moves upward, there is a gap between it and the surface of the composite busbar 1, thereby providing space for the positioning plate 42 to move, and after the extension bar 6 further bends the bent portion, the driving rod 132 is reset, thereby resetting the positioning plate 42. That is, better bending of the composite busbar is achieved.

[0051] Reference Figure 4 In a further embodiment, in order to facilitate the removal of the bent composite busbar 1 from the base 2, the base 2 includes a crossbar 202 and columns 201 installed at both ends of the crossbar 202, the vertical rod 10 is installed at the upper end of the column 201, and the composite busbar 1 is placed on the surface of the crossbar 202. A lifting member is installed at the lower end of the crossbar 202, and the lifting member is a device such as an oil cylinder or a hydraulic cylinder. When the bending is completed, the lifting member drives the crossbar 202 to move downward, so that the composite busbar 1 is easy to remove.

[0052] The implementation principle of a bending device in an embodiment of the present application is as follows: in the initial state, the driving rod 132 is in a vertical state, and the bending plate 41 is in a horizontal state. The driving rod 132 moves downward so that the positioning rod 32 abuts against the surface of the composite busbar 1, and then the rotating disk 131 rotates, the driving rod 132 is reset, the driving rod 132 abuts against the protruding column 19 and pushes the sliding block 8 to slide, driving the bending plate 41 to move, and the bending plate 41 can bend the composite busbar 1. After the bending is completed, the bending plate 41 is reset to a horizontal state, the driving rod 132 rotates to a horizontal state, the driving rod 132 moves in a direction close to the base 2, and drives the positioning plate 42 to slide, and the contact bar 15 drives the positioning rod 32 to slide upward; the extension bar 6 can be pressed against the bent part of the composite busbar 1, thereby further bending the part. Example

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
