Description

Technical Field

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

[0002] High-speed wire processing machines are essential for modern wire harness manufacturing, especially for high-frequency data cables, automotive wire harnesses, and other wires with independent ground wires. After the shielding and insulation layers are stripped, the exposed ground wires typically undergo specific shaping and bending processes.

[0003] Patent document CN119114788A discloses a dual ground wire shaping system and method for high-speed wires. This system includes a ground wire picking module and a ground wire flipping module. The shaping process involves using these modules to perform three bending operations on the two ground wires sequentially, ultimately completing the ground wire shaping. However, this device and method are designed for specific wires with a dual ground wire structure. Its module structure and operation flow are based on the synchronous processing of both ground wires, limiting its applicability and making it difficult to apply to the shaping of other types of wires with single ground wires or varying numbers of ground wires.

[0004] Therefore, it is necessary to design a new utility model to solve the above-mentioned technical problems. Utility Model Content

[0005] The main objective of this invention is to provide a wire bending device that can perform high-precision and high-efficiency bending operations on single ground wire structures, improve the shaping efficiency of single ground wires, and meet the requirements for automatic bending of ground wires.

[0006] This utility model achieves the above objective through the following technical solution: a wire bending device for bending a ground wire, wherein the ground wire includes a first section and a second section, comprising: The first bending blade includes a first working surface located at one end in the second direction, a supporting plane located at the top end, and an edge adjacent to the first working surface and the supporting plane. The second bending blade is located above the first bending blade and includes a second working surface located at its lower end; The first electric cylinder drives the first bending cutter to move along the second direction, and uses the first working surface to push the first section to the target state. The second electric cylinder drives the second bending blade to move in the first direction opposite to the second direction, using the second working surface to press the second section onto the support plane and straighten the second section along the first direction.

[0007] Furthermore, a first groove conforming to the shape of the ground wire is provided on the first working surface.

[0008] Furthermore, the opening of the first groove faces the second direction and extends vertically.

[0009] Furthermore, the first groove extends vertically through the upper and lower ends of the first working surface.

[0010] Furthermore, a second groove conforming to the shape of the ground wire is provided on the second working surface.

[0011] Furthermore, the opening of the second groove faces downwards.

[0012] Furthermore, the second groove extends through the first direction or the second direction.

[0013] Furthermore, it also includes a cylinder that drives the second bending blade to move up and down.

[0014] Furthermore, a support plate is provided at the movable end of the second electric cylinder, the cylinder is fixed on the support plate, and the second bending blade is installed at the movable end of the cylinder.

[0015] Furthermore, the first segment and the second segment are adjacent to point A, and the first bending blade moves along the second direction at a set height position. The set height is: the height of the edge is consistent with the height of point A in the ground line in the target state.

[0016] Compared with the prior art, the beneficial effects of this utility model's wire bending device are as follows: (1) High bending accuracy and stable and reliable forming quality: By setting two contour grooves that match the shape of the ground wire, the ground wire is effectively limited and held when bending the first section and flattening the second section, respectively. This prevents the wire from shifting, sliding or twisting in the third direction during the bending process, ensuring the accurate position of the bending inflection point. The final vertical and horizontal sections have excellent consistency in angle and shape, avoiding quality fluctuations caused by manual operation. (2) High degree of automation and significantly improved production efficiency: The device adopts multi-directional drive components such as the first electric cylinder, the second electric cylinder and the pneumatic cylinder, and with program control, it realizes fully automatic or semi-automatic bending and forming of the ground wire from the initial state to the first state and then to the second state (target state), which reduces the labor intensity and skill requirements of the operators and improves efficiency.

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to specific embodiments.

[0019] Example 1: Please refer to Figures 1-10 This embodiment provides a wire bending device 100, which includes a frame 1, a first electric cylinder 2 and a second electric cylinder 4 fixedly mounted on the frame 1, a first bending blade 3 driven by the first electric cylinder 2 to move along a first direction and a second direction, a support plate 5 driven by the second electric cylinder 4 to move along the first direction and the second direction, a cylinder 6 fixedly mounted on the support plate 5, and a second bending blade 7 driven by the cylinder 6 to move up and down and located above the first bending blade 3. The first direction is opposite to the second direction.

[0020] In this embodiment, the wire 200 is a single ground wire structure, meaning that the wire 200 includes one ground wire 201 and two conductors 202. This embodiment primarily involves shaping the ground wire 201 within the wire 200. In other embodiments, the number of conductors 202 in the wire 200 can be set to two or more; this embodiment does not impose a limitation.

[0021] In this embodiment, the ground wire 201 in the wire 200 includes a first segment 2011 extending from the root to the free end and a second segment 2012 extending from the end of the first segment 2011 to the free end. The first segment 2011 and the second segment 2012 are adjacent to point A.

[0022] In this embodiment, the wire bending device 100 bends the wire 200, bending it from an initial state to a first state, and then from the first state to a second state. A schematic diagram of the state change structure of the wire 200 in this embodiment is shown below. Figure 3 As shown; where: The initial state is as follows: the ground wire 201 is a straight structure and is tilted upward at a first angle (i.e., the angle between the ground wire 201 and the first direction), and the conductor 202 is set to extend horizontally along the first direction; The first state is: the ground wire 201 is a straight structure and is tilted upward at a second angle (i.e., the angle between the ground wire 201 and the first direction), the second angle is greater than the first angle, and the conductor 202 is set to extend horizontally along the first direction; The second state is as follows: the first segment 2011 maintains the pose state in the first state, the second segment 2012 extends horizontally in the first direction in the height space above the conductor 202, the inflection point of the bend of the first segment 2011 and the second segment 2012 coincides with point A, and the conductor 202 is set to extend horizontally in the first direction.

[0023] In this embodiment, the wire bending device 100 can be connected after the device in the initial forming state, or it can be manually operated to the initial state. The first state is achieved by the first electric cylinder 2 driving the first bending blade 3 to act on the first section 2011 of the ground wire 201; the second state is achieved by the second electric cylinder 4 cooperating with the cylinder 6 to drive the second bending blade 7 to act on the second section 2012.

[0024] The first bending blade 3 acts on the first section 2011, which includes a first working surface 31 located at one end in the second direction, a supporting plane 32 located at the top, and an edge 33 adjacent to the first working surface 31 and the supporting plane 32. In order to ensure that the ground wire 201 does not shift in the third direction (the third direction is perpendicular to the first and second directions) when it reaches the first state, a first groove 311 that conforms to the shape of the ground wire 201 is provided on the surface of the first working surface 31.

[0025] The operation process of bending the wire 200 from the initial state to the first state is as follows: The first electric cylinder 2 drives the first bending knife 3 to move along the second direction, and uses the first groove 311 on the first working surface 31 to push the first section 2011 of the ground wire 201 to the design state (i.e., set at a second angle with the second direction). At this time, the ground wire 201 is lifted up at the second angle and reaches the first state.

[0026] The second bending blade 7 acts on the second section 2012, which includes a second working surface 71 located at its lower end. In order to ensure that the second section 2012 of the ground wire 201 does not deviate upward in the third direction during the horizontal extension of the ground wire 201 in the first direction, a second groove 711 that conforms to the shape of the ground wire 201 is provided on the second working surface 71.

[0027] In this embodiment, the operation process of bending the wire 200 from the first state to the second state is as follows: After the wire 200 reaches the first state, the first bending blade 3 remains stationary. The second electric cylinder 4 drives the second bending blade 7 to move along the second direction to the first set position (e.g., ...). Figure 8 (b) As shown, if the height of the second bending blade 7 is higher than point A, the cylinder 6 drives the second bending blade 7 to move downward to the same horizontal plane as point A, and uses the second groove 711 on the second working surface 71 to press down the second section 2012; then, the second electric cylinder 4 drives the second bending blade 7 to move along the first direction, pressing the second section 2012 onto the support plane 32. As the second bending blade 7 moves along the first direction, the second section 2012 is shaped and straightened on the support plane 32, and the wire 200 reaches the second state.

[0028] The overall workflow of Example 1 is as follows: Figure 8 As shown, its working process is as follows: The second electric cylinder 4 drives the second bending cutter 7 to move along the second direction to the first set position. At the same time, the first electric cylinder 2 drives the first bending cutter 3 to move along the second direction, so that the first groove 311 on the first working surface 31 matches the ground wire 201, and the edge 33 is aligned with point A. At this time, the first bending cutter 3 continues to move along the second direction until the ground wire 201 is lifted upward at the second angle. At this time, the wire 200 reaches the first state, and the first bending cutter 3 remains stationary. If at this time... When the height of the second bending blade 7 is higher than point A, the cylinder 6 drives the second bending blade 7 to move downward until it is at the same level as point A, so that the second groove 711 on the second working surface 71 matches the ground wire 201. Subsequently, the second electric cylinder 4 drives the second bending blade 7 to move along the first direction, pressing the second section 2012 onto the support plane 32. As the second bending blade 7 moves along the first direction, the second section 2012 is straightened on the support plane 32, at which point the wire 200 reaches the second state.

[0029] Example 2: This embodiment is a wire bending device 100 with the same structure as Embodiment 1, the difference being: The first state is different. In this embodiment, the first state is: the ground wire 201 has a bent structure and includes a first segment 2011 near the root and a second segment 2012 bent at an angle to the first segment 2011. The first segment 2011 extends upward at a third angle (i.e., the angle between the first segment 2011 and the first direction), the third angle being greater than the first angle and equal to the second angle. The second segment 2012 extends upward at a fourth angle (i.e., the angle between the second segment 2012 and the first direction), the fourth angle being less than or equal to 90°. The conductor 202 extends horizontally along the first direction. The schematic diagram of the state change structure of the wire 200 in this embodiment is shown below. Figure 9 As shown.

[0030] The overall workflow of Example 2 is as follows: Figure 10 As shown, its working process is as follows: The second electric cylinder 4 drives the second bending cutter 7 to move along the second direction to the second set position (e.g., Figure 10 (b) As shown, simultaneously, the first electric cylinder 2 drives the first bending blade 3 to move along the second direction, so that the wire 200 reaches the first state, and the first bending blade 3 remains stationary; at this time, the root of the second section 2012 is inserted into the third groove 711 at the bottom of the second action surface 71 when the ground wire 201 is pushed by the first action surface 31 along the second direction, and under the support of the edge 33, the ground wire 201 bends at point A to form an inflection point; if the height of the second bending blade 7 is higher than point A, the cylinder 6 drives the second bending blade 7 to move downward to the same horizontal plane as point A, pressing the second section 2012 onto the support plane 32; subsequently, the second electric cylinder 4 drives the second bending blade 7 to move along the first direction, straightening the second section 2012 on the support plane 32, at which time the wire 200 reaches the second state.

[0031] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
