Description

Technical Field

[0001] This invention relates to the field of wire processing technology, and in particular to a bending device. Background Technology

[0002] In related technologies, during the processing of wires, bending is required based on usage needs to obtain the desired shape and contour. For example, the Ipin and Upin bending of hairpin flat wires is a key process in flat wire forming, determining the precision and quality of the flat wire forming.

[0003] However, the compatibility between bending equipment for wires with different shapes and profiles is poor, and the efficiency and stability of wire bending are low. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide a bending device that has good compatibility and high bending efficiency.

[0061] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0062] The following is for reference. Figures 1-11 A bending device 10001000 according to an embodiment of the present invention is described.

[0063] like Figure 1 As shown, the bending device 1000 according to an embodiment of this application includes: a bending device 100, a conveying device 200, and a material transfer device 300.

[0064] The bending device 100 has a bending section 140, which is adapted to bend the wire 2 to a predetermined angle; the conveying device 200 has a first conveying section 211 that moves in a first direction and a second conveying section 212 that is connected to the first conveying section 211 and can move in a second direction, and the second conveying section 212 is provided with a first gripping claw 2121 for gripping and conveying the wire 2; the material transfer device 300 has a third conveying section 310 that moves in a third direction, and the third conveying section 310 is provided with a second gripping claw 311 for gripping and conveying the wire 2, and the second gripping claw 311 and the first gripping claw 2121 are opposite each other in the third direction.

[0065] The first gripper 2121 is adapted to move along a first direction to pick up and place the line 2 on the bend. The first gripper 2121 is adapted to move along a second direction to move the line 2 along the second direction. The second gripper 311 is adapted to move along a third direction to move the line 2 along the third direction. The first direction, the second direction, and the third direction are orthogonal to each other.

[0066] Specifically, the bending device 100 bends the line 2, the conveying device 200 can pick up and put the line 2 on the bending device 100, and the line moving device can move the line 2 in a third direction so that after completing the bending in one area, it can be moved to another area for bending. Thus, the bending device 100, the conveying device 200 and the line moving device can be used to realize continuous bending and transfer of a line 2.

[0067] According to the embodiment of this application, the wire processing equipment can bend wires with different profiles by setting up a bending device 100, a conveying device 200 and a wire transfer device. It has strong compatibility and higher wire bending efficiency and stability.

[0068] See Figure 2 As shown, according to some embodiments of this application, there are multiple bending devices 100, and the bending portion 140 of each bending device 100 is adapted to bend the line 2 to different angles. The number of first gripping claws 2121 is one more than the number of bending portions 140, and the number of second gripping claws 311 is the same as the number of bending portions 140. The bending device 100, in conjunction with the conveying device 200 and the material transfer device 300, can realize the bending of various lines 2 with different bending trajectories and different bending times.

[0069] For example, such as Figure 12 As shown, the line body 2 that needs to be bent includes a first line body 2a that needs to be bent twice in one direction and a second line body 2b that is U-shaped and needs to be bent three times. There are four bending devices 100, and the workstations are defined as the first workstation, the second workstation, the third workstation, and the fourth workstation. The angle of the second bend of the first line body 2a is the same as the angle of the second bend of the second line body 2b. So the first workstation can perform one bend of the first line body 2a, the second workstation can perform one bend of the second line body 2b, the third workstation can perform two bends of the first line body 2a and the second line body 2b, and the fourth workstation can perform three bends of the second line body 2b to obtain two different lines body 2.

[0070] Furthermore, multiple bending devices 100 are provided, and the bending part 140 of each bending device 100 can bend the line body 2 at different angles. The bending of different line bodies 2 at the same bending angle can be performed by the same bending device 100. The movement of the line body 2 between multiple bending devices 100 can be achieved by a transport device 200. The bending of different areas of the line body 2 can be achieved by a line transfer device. This allows the bending equipment 1000 of this application embodiment to bend line bodies 2 with various different outlines, improves the compatibility of the bending equipment 1000, increases bending efficiency, and reduces bending costs.

[0071] The bending device 1000 further includes a power unit 400, which includes at least one power source and is used to drive the bending device 100, the conveying device 200, and the material transfer device 300.

[0072] The bending device 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0073] like Figures 3-6 As shown, the bending device 100 according to an embodiment of the present invention includes a cam 110, a power source, two clamping blocks and a bending section 140.

[0074] The cam 110 is rotatable between a first position and a third position, and also has a second position between the first and third positions. A power source is driven to the cam 110. At least one of the two clamping blocks is driven to the cam 110. A bent portion 140 is provided on the cam 110 and offset from the rotation axis of the cam 110.

[0075] In the first position, the cam 110 has a gap between the two clamping blocks that is suitable for the thread 2 to pass through, and the bending part 140 is spaced apart from the thread 2. In the second position, the two clamping blocks together hold the thread 2. During the process of the cam 110 rotating from the second position to the third position, the bending part 140 is suitable for bending the thread 2 to a predetermined angle.

[0076] It should be understood here that the "predetermined angle" can be set by those skilled in the art according to actual needs. "During the rotation of the cam 110 from the second position to the third position, the bending part 140 is adapted to bend the line 2 to the predetermined angle" can mean that the bending part 140 of the cam 110 starts bending the line 2 when it is in the second position, or it can mean that the bending part 140 of the cam 110 starts bending the line 2 at a certain position between the second and third positions.

[0077] Specifically, the transmission connection between the cam 110 and the clamping block can be achieved by the edge of the cam 110 abutting against the clamping block, or by a cam-linkage mechanism or other means.

[0078] When bending the wire 2, the wire 2 is first placed between the two clamping blocks through the gap. Then, the power unit 400 drives the cam 110 to start rotating. The cam 110 drives at least one of the two clamping blocks to move. During the rotation, the cam 110 reaches the second position, so that the two clamping blocks jointly hold the wire 2. The cam 110 continues to rotate from the second position to the third position. During this process, the bending part 140 is driven to bend the wire 2.

[0079] In short, during the process of the cam 110 rotating from the first position to the third position, the two clamping blocks are first driven to hold the wire body 2, and then the bending part 140 is driven to bend the wire body 2.

[0080] Then cam 110 rotates from the third position back to the first position, preparing for the next bending action.

[0081] According to an embodiment of the present invention, the bending device 100 is configured with a cam 110, at least one of the two clamping blocks is connected to the cam 110 for transmission, and the bending part 140 is disposed on the cam 110. Thus, the cam 110 can drive the clamping blocks to clamp the wire, and drive the bending part 140 to bend the wire. Moreover, the clamping and bending actions can be completed sequentially during one rotation of the cam 110, allowing the cam 110 to complete both clamping and bending actions in one step during one rotation. Compared with related art flat wire bending devices that perform clamping and bending in separate steps, this effectively improves bending efficiency, thereby increasing the production efficiency of the motor.

[0082] Furthermore, by using cam 110 to drive the clamping block and placing the bending part 140 on cam 110, only cam 110 needs to be driven to rotate. Compared with bending devices in related technologies where clamping and bending each have independent power sources, bending device 100 only needs one power source, which can reduce the overall cost of bending device 100. Moreover, the clamping and bending actions are completed sequentially by one rotation of cam 110, which can avoid the problem of bending before complete clamping caused by using independent power sources, thereby simplifying the control difficulty of bending device 100.

[0083] Furthermore, by clamping before bending, compared to bending devices in related technologies that do not have clamping devices, the line body 2 can be positioned before bending, ensuring the consistency of bending.

[0084] Furthermore, by using the cam 110 and clamping block to directly mount the bending part 140 on the cam 110, compared with the related technology that uses a complex gear set to link the clamping device and the bending device, the cost of using the cam 110 for transmission is lower, and there is no need for multi-stage gear set transmission. The clamping and bending actions are faster, thereby further shortening the bending time and improving bending efficiency.

[0085] Therefore, the bending device 100 according to the embodiments of the present invention has advantages such as high bending efficiency, low cost, low control difficulty, and good bending consistency.

[0086] In some specific embodiments of the present invention, the bending device 100 according to the present invention includes a cam 110, a power source, two clamping blocks and a bending portion 140.

[0087] Advantageously, such as Figure 4As shown, when the cam 110 is in the second position, the bending portion 140 is in contact with the wire body 2. This allows the two clamping blocks to clamp the wire body 2 while the bending portion 140 is in contact with the wire body 2. As the cam 110 rotates from the second position to the third position, it begins to bend the wire body 2, making the clamping and bending actions continuous, reducing the waiting time between the clamping and bending actions, and further improving the bending efficiency of the bending device 100.

[0088] Specifically, the bending device 100 also includes a fixed base 150 and a movable plate 160. The two clamping blocks are a fixed clamping block 131 and a movable clamping block 132, with the fixed clamping block 131 mounted on the fixed base 150. The movable plate 160 is slidably mounted on the fixed base 150, and the movable clamping block 132 is mounted on the movable plate 160. The movable plate 160 has an abutment member that abuts against the edge of the cam 110. Thus, the rotation of the cam 110 drives the abutment member abutting against the edge of the cam 110 to move, causing the movable plate 160 to slide relative to the fixed base 150. Ultimately, this causes the fixed clamping block 131 and the movable clamping block 132 to move closer or further apart, thereby achieving the clamping and opening of the two clamping blocks.

[0089] More specifically, such as Figures 3-5 As shown, the abutment is a roller, which is rotatably mounted on the movable plate 160. This allows rolling friction to form between the abutment and the edge of the cam 110, reducing frictional resistance and wear.

[0090] Furthermore, such as Figures 3-5 As shown, there are two abutment members, located on the radial sides of the cam 110 respectively. This allows the cam 110 to lift one abutment member when the movable clamping block 132 is clamping, and to lift the other abutment member when the movable clamping block 132 is resetting, facilitating the driving and resetting of the movable clamping block 132.

[0091] Furthermore, such as Figures 3-5 As shown, the two abutting members are a first abutting member 161 and a second abutting member 162. The edge of the cam 110 includes a connected convex section 111 and a concave section 112. In a first position, the concave section 112 abuts against the first abutting member 161 and the convex section 111 abuts against the second abutting member 162. In a second position, the convex section 111 abuts against the first abutting member 161 and the concave section 112 abuts against the second abutting member 162. Specifically, in a third position, the convex section 111 abuts against the first abutting member 161 and the concave section 112 abuts against the second abutting member 162. There is a rounded transition between the convex section 111 and the concave section 112. This facilitates the driving and resetting of the movable clamping block 132.

[0092] Figure 6A bending device 100 according to some examples of the present invention is shown. A power source is connected to a cam 110 via a drive shaft 121, and a drive shaft seat 151 is provided on a fixed base 150, in which the drive shaft 121 is rotatably fitted. This facilitates the driving of the cam 110 and improves the stability of the cam 110's rotation.

[0093] Specifically, such as Figure 6 As shown, at least one of the two clamping blocks has a clamping groove 133. This facilitates the positioning of the line body 2.

[0094] Advantageously, such as Figures 3-5 As shown, the bending part 140 is a bending wheel and is rotatably mounted on the cam 110. This allows rolling friction to be generated between the bending part 140 and the line body 2, reducing resistance and wear, thereby facilitating the bending of the line body 2.

[0095] Optionally, such as Figures 3-5 As shown, the cam 110 rotates at an angle of less than 180 degrees between the first and third positions, and at an angle of less than 90 degrees between the first and second positions. This facilitates control of the rotation angle of the cam 110 during clamping and bending actions, further improving the bending efficiency of the bending device 100.

[0096] The following is for reference. Figures 7-10 A conveying device 200 according to an embodiment of the present invention is described.

[0097] like Figure 7 and Figure 8 As shown, the conveying device 200 according to a first aspect embodiment of the present invention includes: a conveying unit 210, a power input terminal 220, a first cam drive group 230, a second cam drive group 240, a first power output terminal 250, and a second power output terminal 260.

[0098] The conveying unit 210 includes a first conveying part 211 that moves in a first direction and a second conveying part 212 that is connected to the first conveying part 211 and can move in a second direction. The second conveying part 212 is provided with a first gripping claw 2121 for gripping and conveying. The item to be conveyed can be fixed on the first gripping claw 2121, and under the action of the first conveying part 211, the item can move in the first direction. Under the action of the second conveying part 212, the item can move in the second direction, so as to realize the conveying of the item.

[0099] Of course, the structure of the transport unit 210 in this embodiment of the invention is not limited to this. In other embodiments, the first transport part 211 may also be provided with a first gripper 2121. Items that only need to be transported in the first direction can be transported by placing them on the first gripper 2121 of the first transport part 211.

[0100] The first cam drive group 230 and the second cam drive group 240 are coaxially arranged and both are powered by the power input end 220. The first power output end 250 is powered by the first cam drive group 230 and is adapted to drive the first transport part 211 to move in the first direction. The second power output end 260 is powered by the second cam drive group 240 and is adapted to drive the second transport part 212 to move in the second direction. The first power output end 250 and the second power output end 260 are driven by the coaxially arranged first cam drive group 230 and second cam drive group 240 respectively. The first power output end 250 then drives the first transport part 211 and the second transport part 212 of the transport unit 210 to move as a whole in the first direction. The second power output end 260 drives the second transport part 212 to move relative to the first transport part 211 in the second direction.

[0101] Among them, see Figure 9 and Figure 10 As shown, the first direction and the second direction have an angle between them.

[0102] Understandably, in the prior art, in order to enable the conveying unit 210 to move along a first direction and a second direction with an angle, two power input terminals 220 need to be set up. One power input terminal 220 drives in the first direction and the other power input terminal 220 drives in the second direction. This results in a larger number of power input terminals 220, higher costs, and the two power input terminals 220 need to be driven in steps. The synchronization between the driving in the first direction and the driving in the second direction is poor, resulting in low driving efficiency and reduced production efficiency. Furthermore, multiple power input terminals 220 need to be controlled separately, which complicates the control logic and reduces operational stability.

[0103] In contrast, with the present invention, after power is input at the power input terminal 220, the first cam drive group 230 and the second cam drive group 240 can be driven simultaneously. The number of power input terminals 220 is less, the cost is lower, the synchronization of the two cam drive groups is good, which can improve production efficiency, and there is no need to control them separately. The control logic is simple, and it is only necessary to control the first cam drive group 230 and the second cam drive group 240 to rotate synchronously. The control logic is simple and the working stability is high.

[0104] According to the embodiment of the present invention, the conveying device 200, by setting a first cam drive group 230 and a second cam drive group 240 coaxially, realizes the synchronous movement of the first conveying part 211 and the second conveying part 212 in a first direction through the first cam drive group 230 and the second cam drive group 240 respectively, and the movement of the second conveying part 212 relative to the first conveying part 211 in a second direction, can reduce the cost of the conveying device 200, improve production efficiency, simplify control logic, and improve the working stability of the conveying device 200.

[0105] like Figure 8 and Figure 9 As shown, according to some embodiments of the present invention, the first cam drive group 230 includes: a first cam disk 231 and a first follower bearing 232. The first cam disk 231 has a first cam groove 2311, the first follower bearing 232 is disposed in the first cam groove 2311, and the first follower bearing 232 is poweredly connected to the first power output terminal 250; the second cam drive group 240 includes: a second cam disk 241 and a second follower bearing 242. The second cam disk 241 has a second cam groove 2411, the second follower bearing 242 is disposed in the second cam groove 2411, and the second follower bearing 242 is poweredly connected to the second power output terminal 260.

[0106] Specifically, the first follower bearing 232 slides within the first cam groove 2311. The variable diameter portion of the first cam groove 2311 can push the first follower bearing 232 to perform linear reciprocating motion in a first direction, thereby pushing or pulling the first power output end 250. The first power output end 250 then outputs the linear motion in the first direction to the first transport part 211, so that the first transport part 211 and the second transport part 212 move synchronously in the first direction. The second follower bearing 242 slides within the second cam groove 2411. The variable diameter portion of the second cam groove 2411 can push the second follower bearing 242 to perform linear reciprocating motion in a second direction, thereby pushing or pulling the second power output end 260. The second power output end 260 outputs the linear motion in the second direction to the second transport part 212, so that the second transport part 212 performs reciprocating motion in the second direction relative to the first transport part 211.

[0107] This improves the smoothness and reliability of the movement of the first transport unit 211 and the second transport unit 212, and ensures higher drive synchronization of the coaxially arranged first cam drive group 230 and second cam drive group 240. Coaxial rotation can achieve separate drive in the first and second directions, resulting in a lower probability of interference, higher working stability, and higher production efficiency.

[0108] It is understandable that the variable diameter portion of the first cam groove 2311 and the variable diameter portion of the second cam groove 2411 are arranged to coincide or stagger in the axial direction so that the movement of the first transport portion 211 and the second transport portion 212 is synchronous or asynchronous.

[0109] In other words, according to the working requirements of the conveying device 200, if the movement of the first conveying part 211 and the second conveying part 212 needs to be synchronized (synchronized), that is, while the first conveying part 211 moves in the first direction, the second conveying part 212 moves in the second direction, then the axial projections of the variable diameter part of the first cam groove 2311 and the variable diameter part of the second cam groove 2411 can be made to coincide, so that the first power output end 250 and the second power output end 260 can output power simultaneously. If the movement of the first conveying part 211 and the second conveying part 212 needs to be asynchronous (sequential), then the axial projections of the variable diameter part of the first cam groove 2311 and the variable diameter part of the second cam groove 2411 can be staggered to achieve sequential movement in the first direction and the second direction, thereby improving the applicability of the conveying device 200.

[0110] For example, taking the hairpin flat wire conveying device 200 as an example, the power input end 220 drives the first cam disk 231 and the second cam disk 241 to rotate simultaneously. The variable diameter portions of the first cam groove 2311 and the second cam groove 2411 are staggered in axial direction. The surface curve of the first cam groove 2311 pushes the first follower bearing 232, and the variable diameter portion of the first cam groove 2311 pushes the first follower bearing 232 to make linear motion, so that the first power output end 250 outputs power. At this time, the second cam groove 2411 does not push the second follower bearing 242 to make linear motion. The power input end 220 continues to drive the first cam disk 231 and the second cam disk 241 to rotate. The first cam groove 2311 rotates to the equal diameter section, and the first follower bearing 232 stops moving. Meanwhile, the variable diameter section of the second cam groove 2411 pushes the second follower bearing 242 to move linearly, so that the second power output end 260 outputs power. This cyclical motion realizes the cyclical transport action of the first direction forward, the second direction forward, the first direction reverse, and the second direction reverse; such as the cyclical and continuous action of left to right, bottom to top, right to left, and top to bottom, to significantly improve transport efficiency.

[0111] like Figure 9 and Figure 10 As shown, in some embodiments, the conveying device 200 further includes: a platform 270, a first conveying unit 211 movably disposed on the platform 270 along a first direction, and a second conveying unit 212 movably disposed on the first conveying unit 211 along a second direction. Thus, while realizing the movement of the conveying unit 210 in a predetermined direction, the overall structural stability and reliability of the conveying device 200 can be improved.

[0112] like Figure 7 and Figure 9 As shown, the first power output end 250 further includes a push rod 251 and a lever 252. One end of the push rod 251 is connected to the first cam drive group 230, and the other end of the push rod 251 is connected to one end of the lever 252. The lever 252 is rotatably mounted on the platform 270, and the other end of the lever 252 is connected to the first transport part 211 to push the first transport part 211.

[0113] Specifically, the platform 270 includes a base plate 271 and a support column 272. A lever fulcrum 2711 is provided on the base plate 271. A first transport part 211 is provided on the support column 272 so that the first transport part 211 is spaced apart from the base plate 271. A lever 252 is located between the first transport part 211 and the base plate 271, and the other end of the lever 252 is connected to the connecting rod 2113 of the first transport part 211 to push the first transport part 211.

[0114] Thus, lever 252 can rotate relative to base plate 271. One end of lever 252 located on one side of lever fulcrum 2711 forms a first arm, and the other end located on the other side of lever fulcrum 2711 forms a second arm. The first arm is connected to push rod 251, and the second arm is connected to connecting rod 2113 of first transport part 211. Push rod 251 pushes the first arm, and the first arm drives the second arm to move in the opposite direction. The second arm pushes or pulls connecting rod 2113. Connecting rod 2113 is slidably engaged with guide cylinder 2114 so that one end of connecting rod 2113 extends or retracts from guide cylinder 2114, while pushing first transport part 211 to move in the first direction, which can further improve the movement stability of first transport part 211.

[0115] The length of the first arm can be greater than the length of the second arm to form a force-saving lever 252, reducing the driving force requirement. Alternatively, the length of the first arm can be less than the length of the second arm to form a force-consuming lever 252, while making the movement distance control of the first conveying unit 211 in the first direction more precise.

[0116] like Figure 7 As shown, the first transport unit 211 includes a fixed plate 2111 and a movable plate 2112. A connecting rod 2113 is provided between the fixed plate 2111 and the movable plate 2112. The movable plate 2112 is movably connected to the second transport unit 212. The fixed plate 2111 is connected to the support column 272.

[0117] In other words, the fixed plate 2111 and the movable plate 2112 are arranged opposite to each other in the first direction. The fixed plate 2111 is fixed on the support column 272, and the movable plate 2112 is connected to the second transport part 212. The movable plate 2112 can move relative to the fixed plate 2111. Multiple guide cylinders 2114 can be arranged at intervals in the length direction between the fixed plate 2111 and the movable plate 2112. Each guide cylinder 2114 is provided with a connecting rod 2113. The connecting rod 2113 can move along the first direction under the action of the guide cylinder 2114 to push the movable plate 2112 to move relative to the fixed plate 2111. At least one connecting rod 2113 located in the middle area is connected to the lever 252 of the first power output end 250, which can realize the movement of the first transport part 211 in the first direction, improve the force distribution of the first transport part 211, and further improve the smoothness and reliability of the movement of the first transport part 211.

[0118] like Figure 7 and Figure 9 As shown, in some embodiments, the second power output end 260 includes a lever 261 and a push block 262. One end of the lever 261 is connected to the second cam drive group 240, and the other end of the lever 261 is slidably disposed in the groove 2621 of the push block 262. The push block 262 is fixed to the second transport part 212.

[0119] Specifically, the second follower bearing 242 drives the lever 261 to move. The lever 261 moves the push block 262 within the groove 2621 to realize the movement of the second transport unit 212 in the second direction. The push block 262 is provided with the groove 2621. While the lever 261 moves the push block 262, it can slide within the groove 2621 to avoid dead points and improve the mechanical movement stability of the second power output end 260, thereby improving the working stability of the transport device 200.

[0120] like Figure 7 As shown, the first transport unit 211 and the second transport unit 212 are movably connected via the guide rail 213.

[0121] Specifically, a guide rail 213 can be provided on the movable plate 2112 and a slider can be provided on the second transport part 212 to achieve a sliding fit between the two in the second direction. Alternatively, a guide rail 213 can be provided on the second transport part 212 and a slider can be provided on the movable plate 2112 to achieve a sliding fit between the two in the second direction.

[0122] According to some embodiments of the present invention, the power input end 220 is configured as an input shaft, and the first cam drive group 230 and the second cam drive group 240 are disposed on the input shaft. In this way, not only can the space occupation of the conveying device 200 be reduced, making the spatial arrangement of the conveying device 200 more compact, but also the synchronization of the first cam drive group 230 and the second cam drive group 240 can be further improved, thereby improving the working stability and production efficiency of the conveying device 200.

[0123] It should be noted that the power unit 400 can have multiple power sources, which can be configured as motors, cylinders, hydraulic cylinders, etc.

[0124] like Figure 11 As shown, the material transfer device 300 includes a third transport unit 310 and a transmission group. The third transport unit 310 is poweredly connected to the transmission group and drives the second gripper 311 to move toward or away from the bending part 140 to realize the supply of the line 2.
