Description

Technical Field

[0001] The utility model relates to the technical field of new energy, and particularly relates to a bus bar bending device. Background Art

[0002] New energy, also known as unconventional energy, refers to various forms of energy other than traditional energy. Generally, it refers to renewable energy developed and utilized on the basis of new technologies, including solar energy, biomass energy, wind energy, geothermal energy, wave energy, ocean current energy, tidal energy, and the thermal cycle between the ocean surface and deep layers. New energy vehicles refer to vehicles that use unconventional vehicle fuels as the power source (or use conventional vehicle fuels and adopt new in-vehicle power devices), and integrate advanced technologies in the power control and drive aspects of the vehicle to form vehicles with advanced technical principles, new technologies, and new structures. Common new energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. In new energy vehicles with an electric drive mode, wires for transmitting electric energy are required, and generally flat copper bus bars and aluminum bus bars are used. According to the design of different products, the shape of the bus bar needs to match the product. During the processing of the bus bar, the bus bar needs to be bent to meet the requirements of the product. Currently, during the bending process, there is a method of bending the bus bar by stamping, that is, through two upper and lower molds, and the bus bar is pressed and bent by pressure. However, such a method is mostly used for bending operations in the thickness direction of the bus bar. For a bus bar that needs to be bent in the width direction, if such a method is directly used to stamp from the side of the bus bar, it is easy to cause deformation or even damage to the bus bar, and it is difficult to achieve the bending operation in the width direction of the bus bar.

Specific embodiments

[0023] To facilitate those skilled in the art to understand the present utility model, the present utility model will be further described in detail below in conjunction with specific embodiments and the accompanying drawings.

[0024] Referring to Figures 1 to 4 , the present utility model provides a busbar bending device, including a base 1, an incoming line mechanism 2 disposed on the base 1, a bending mechanism 3 disposed on the base 1, a support frame 11 disposed on the base 1, and a pressing mechanism 4 disposed on the support frame 11 and matching with the bending mechanism 3. The incoming line mechanism 2 is used to introduce the busbar. After the busbar passes through the incoming line mechanism 2, it reaches the bending mechanism 3. The pressing mechanism 4 presses the busbar and cooperates with the bending mechanism 3 to bend the busbar.

[0025] The bending mechanism 3 includes a first connecting column 31 rotatably connected to the base 1, a bending seat 32 provided on the connecting column, and a first driving member 33 provided at the bottom of the base 1. The first driving member 33 is in transmission connection with the first connecting column 31. A first bending boss 34 and a second bending boss 35 are provided on the bending seat 32, and there is a receiving position for accommodating the busbar between the first bending boss 34 and the second bending boss 35. The heights of the first bending boss 34 and the second bending boss 35 match the thickness of the busbar. In addition, a receiving groove matching the thickness of the busbar can also be provided at the position of the bending seat 32 corresponding to the receiving position to bend the busbar in the thickness direction. The first driving member 33 uses a motor, and the motor drives the first connecting column 31 to rotate, thereby driving the bending seat 32 to rotate and bend the busbar.

[0026] A plurality of first mounting holes 36 penetrating through the bending seat 32 are provided on the side wall of the bending seat 32. The first mounting holes 36 can be used to mount a heating element, and the heating element heats the pressing block 43, thereby conducting heat to the busbar. Taking an aluminum row busbar as an example, after the busbar is heated, its hardness decreases and stress reduces at high temperature, making it more convenient to bend.

[0027] The incoming line mechanism 2 includes a fixed pipe 21, a wire groove assembly 22 provided in the fixed pipe 21, and a wire pressing assembly 23 connected to the fixed pipe 21 for pressing the busbar; the wire groove assembly 22 includes an incoming line seat 221, a cover plate 222 provided on the incoming line seat 221, and the incoming line seat 221 has a groove 223 for accommodating the busbar, and the end position of the incoming line seat 221 corresponds to the bending seat 32. Both ends of the wire groove assembly 22 are exposed outside the fixed pipe 21, and the wire groove assembly 22 can be pre-set with different sizes according to the specifications of the busbar to be processed and can be replaced as needed during use.

[0028] The wire pressing assembly 23 includes a pressing member 231 movably connected to the fixed pipe 21, a connecting member 232 for connecting the pressing member 231 and the fixed pipe 21, and the pressing member 231 and the connecting member 232 are movably connected, and the bottom end of the pressing member 231 extends into the interior of the fixed pipe 21. The wire pressing assembly 23 can press the busbar during bending to prevent the busbar from shifting. In this embodiment, the connecting member 232 is a screw with a thread at the end, and the thread at the end facilitates connecting the fixed pipe 21, while the non-threaded part enables the pressing member 231 to move.

[0029] The support frame 11 is provided with a second driving member 233 for driving the pressing member 231 to move. In this embodiment, the second driving member 233 uses a cylinder.

[0030] A spring 234 is sleeved on the connecting member 232. One end of the spring 234 is connected to the pressing member 231, and the other end is connected to the fixed pipe 21. Thus, the output end of the second driving member 233 does not need to be fixedly connected to the pressing member 231. After the output end of the second driving member 233 leaves the pressing member 231, the pressing member 231 is separated under the action of the spring 234.

[0031] The fixed pipe 21 is provided with a connection hole 24 for connecting the pressing member 231. There are two cover plates 222, and there is an interval corresponding to the connection hole 24 between the two cover plates 222.

[0032] The fixed pipe 21 is provided with a plurality of second mounting holes 25 along the axial direction. The heating element can be installed in the second mounting holes 25. The heating element heats the fixed pipe 21, and the fixed pipe 21 conducts heat to the internal wire groove assembly 22, thereby heating the busbar.

[0033] The pressing mechanism 4 includes a third driving member 41 arranged on the support frame 11, a second connecting column 42 connected to the third driving member 41, and a pressing block 43 connected to the second connecting column 42 and matching with the bending seat 32. The output end of the third driving member 41 is connected with a lifting plate 44. The second connecting column 42 is connected with the lifting plate 44, and the second connecting column 42 and the lifting plate 44 are rotatably connected to facilitate rotation along with the bending seat 32. At the same time, a torsion spring can be connected. After the pressing block 43 and the bending seat 32 are separated, the elastic force of the torsion spring can drive the pressing block 43 to reset. In this embodiment, a guide rod is further arranged on the base 1, and the guide rod is connected to the lifting plate 44 to make the movement of the lifting plate 44 more stable. In this embodiment, the third driving member 41 adopts a cylinder.

[0034] The pressing block 43 is provided with a plurality of third mounting holes 45, and the heating element can be installed in the third mounting holes 45. The heating element heats the pressing block 43, thereby conducting heat to the busbar.

[0035] During specific use, the busbar is introduced from the starting end of the bending mechanism. After the busbar passes through the wire groove assembly 22, the end reaches the receiving position of the bending seat 32. Then, the pressing block 43 of the pressing mechanism 4 presses down, and the pressing member 231 presses down to press the busbar at two positions. The first driving member 33 drives the bending seat 32 to rotate a certain angle (this angle is the designed angle of the busbar of the corresponding specification). After the bending is completed, each mechanism resets, and the busbar can be pulled out, and at the same time, the next busbar enters the wire groove assembly 22. If both ends of the busbar need to be bent, two bending devices can be set, and the busbar that has completed one - end bending is conveyed to another bending device for the bending operation of the other end.

[0036] The bending mechanism 3 of the present utility model has a bending seat 32. A receiving position is formed between the first bending boss 34 and the second bending boss 35 of the bending seat 32. With the cooperation of the first driving member 33 and the pressing mechanism 4, the folding in the width direction of the busbar can be achieved by the rotation of the bending seat 32, meeting the processing requirements of the busbar, with convenient and fast processing and high efficiency. On the other hand, the first mounting hole 36, the second mounting hole 25 and the third mounting hole 45 of the present utility model can be used to mount a heating element, thereby heating the busbar, reducing the hardness and stress of the busbar, reducing the risk of fracture during the bending process, and ensuring the product quality.
