Description

Technical Field

[0001] This application relates to a device for bending lead wires, belonging to the field of wire bending technology. Background Technology

[0002] Lead wires are widely used in piezoelectric ceramics, electronic components, precision electrical appliances and other products. During the assembly of components, the lead wires need to be precisely bent and shaped according to different assembly size requirements in order to meet the needs of subsequent insertion, soldering and other processes.

[0003] Currently, lead wire bending operations in existing technologies mostly employ manual bending or simple tooling-assisted bending methods. However, manual bending is labor-intensive and inefficient. Differences in human operation can easily lead to inconsistent bending angles and dimensions, resulting in problems such as excessive bending deformation, surface damage, and lead wire breakage, which in turn reduces product yield. Based on the above technical problems, existing technologies use devices to bend the leads. However, simple bending tooling has a simple structure, usually only having a simple placement groove, lacking a stable limiting structure and a precise bending execution structure. The lead wire is prone to offset and misalignment during placement, and the reliability of lead wire positioning during bending is poor, which in turn affects the final bending quality of the lead wire.

[0004] Therefore, there is an urgent need to design a lead wire bending device with a reasonable structure, stable positioning, high bending accuracy, and strong adaptability to solve the above-mentioned defects in the existing technology. Utility Model Content

[0040] refer to Figure 1-6 This application discloses a wire bending device, comprising: a base 10, on which a wire bending groove 11 is provided, a wire bending plate 12 is provided in the wire bending groove 11 along the vertical direction, a first lead wire placement groove 121 is provided at the top of the wire bending plate 12, and a second lead wire placement groove 111 is provided at the top of the side wall of the wire bending groove 11 parallel to the wire bending plate 12, which is aligned with the first lead wire placement groove 121 in the horizontal direction; two first limiting plates 20, which are respectively provided at both ends of the wire bending plate 12 and are fixedly connected to the base 10; and a bending mechanism, which is provided above the base 10 and is used to bend the lead wire 40 placed in the first lead wire placement groove 121 and the second lead wire placement groove 111.

[0041] During use, the straight lead wire 40 to be processed is first placed into the first lead wire placement groove 121 and the second lead wire placement groove 111. The first lead wire placement groove 121 and the second lead wire placement groove 111 work together to support and limit the lead wire 40. The bending mechanism is driven downward by an external power mechanism, so that the lower end of the bending mechanism presses down on the lead wire 40 placed in the first lead wire placement groove 121 and the second lead wire placement groove 111. Using the downward force, the lead wire 40 located between the adjacent bending plates 32 is pressed down to the bottom of the bending groove 11. The lead wire 40 is bent at a fixed point to complete one bend of the lead wire 40. When multiple bends are required on a lead wire 40 in actual operation, after the first bend on the lead wire 40 is completed, the bending mechanism is reset, the lead wire 40 containing the first bend is taken out, and the lead wire 40 that has not yet formed a bend is placed into the first lead wire placement slot 121 and the second lead wire placement slot 111. The above operation is repeated to complete the second bend on the lead wire 40. Then the above steps are repeated, and the number of repetitions is determined according to the number of bends on a lead wire 40.

[0042] This setup offers several advantages: First, it provides stable support and precise positioning for the lead wire 40, effectively limiting its offset and sliding, ensuring accurate bending position and improving the consistency of the bending process. Second, it effectively limits the bending plate 12 at both ends, preventing it from wobbling or shifting during bending, resulting in high overall structural stability. Third, the first lead wire placement groove 121 and the second lead wire placement groove 111 support and limit the lead wire 40, ensuring uniform force distribution during bending and effectively preventing issues such as deformation, breakage, and surface damage, thus improving the product yield.

[0043] refer to Figure 4 and Figure 5 In one embodiment, the bending mechanism includes a fixed base 31, a bending plate 32, and a limiting guide post 33 disposed on the fixed base 31. The fixed base 31 has a first through hole 311 extending vertically through its middle portion. The upper end of the bending plate 32 is slidably connected to the limiting guide post 33. The bending plate 32 can rise or fall along the axial direction of the limiting guide post 33. The lower end of the bending plate 32 extends vertically into the first through hole 311, and the bending plate 32 can rise or fall relative to the first through hole 311.

[0044] During use, the lead wire 40 is first placed in the first lead wire placement slot 121 and the second lead wire placement slot 111. The bending plate 32 in the bending mechanism is driven by the external drive mechanism to move downward along the fixed base 31. During the downward movement, the bending plate 32 extends downward through the first through hole 311 on the fixed base 31 and presses against the lead wire 40. Then, under the continued drive of the external drive mechanism, the lead wire 40 located between the adjacent bending plates 32 is pressed down to the bottom of the bending slot 11, thereby achieving the bending of the lead wire 40. Since the outside of the fixing member is provided with a spring 332, after the force applied by the external drive mechanism is removed, the spring 332 will drive the bending plate 32 to return to its original position. Then, the lead wire 40 containing the first bend is taken out, and the lead wire 40 that has not yet formed a bend is placed into the first lead wire placement slot 121 and the second lead wire placement slot 111 and the above operation is repeated to complete the second bend on the lead wire 40. Then, the above steps are repeated, and the number of repetitions is determined according to the number of bends on a lead wire 40.

[0045] Under this setting, firstly, it effectively avoids the placement of the lead wire 40 being offset or sliding, ensuring the accuracy of the bending point of the lead wire 40 and improving the consistency of the bending angle; secondly, the bending plate 32 limits the movement direction of the bending plate 32 through the limiting guide post 33, ensuring that the movement trajectory of the bending plate 32 is regular and without sway, and ensuring that the force is even when the bending plate 32 is pressed down, which can avoid local pressure damage or twisting deformation of the lead wire 40, protect the structural integrity of the lead wire 40, and improve the processing yield.

[0046] refer to Figure 1 and Figure 4 In one embodiment, there are two limiting guide posts 33, which are arranged on the fixed base 31 and symmetrically arranged along the first through hole 311.

[0047] With this setting, the bending plate 32 can be limited and guided from both sides simultaneously, preventing tilting, deflection or jamming during the downward and upward movement of the bending plate 32, and ensuring linear lifting and lowering motion; at the same time, the two fixing parts are symmetrically subjected to force, so that the downward force of the bending plate 32 is vertically centered and the force is balanced, and the bending force acting on the lead wire 40 is uniform and stable, improving the product processing accuracy.

[0048] refer to Figure 5 In one embodiment, the fixing base 31 is provided with a fixing hole 312, and the limiting guide post 33 passes through the fixing hole 312 and is fixedly connected to the fixing base 31.

[0049] With this configuration, the limiting guide post 33 and the fixed base 31 are tightly connected, preventing loosening or detachment, and ensuring strong connection stability under long-term reciprocating bending operations. Simultaneously, the installation position of the limiting guide post 33 can be precisely defined, preventing it from tilting or shifting, and ensuring the accuracy of the subsequent sliding guidance of the bending plate 32. Furthermore, the limiting guide post 33 is embedded inside the fixing hole 312, making it less prone to shaking or twisting under force, effectively dispersing the force during bending, enhancing the overall structural rigidity of the bending mechanism, and increasing its durability.

[0050] In one embodiment, there are at least two bending plates 12, and the bending plates 12 are arranged in parallel, with the first lead placement grooves 121 of the lead wires 40 on adjacent bending plates 12 aligned.

[0051] With this setup, multiple sets of leads 40 to be bent can be placed simultaneously, and several leads 40 can be bent in one operation, greatly improving the processing efficiency of lead 40 bending and adapting to batch production needs; at the same time, it is not easy to shift or shake during operation, and the structure is stable and reliable under long-term continuous processing.

[0052] refer to Figure 6 In one embodiment, each of the bending plates 12 is provided with at least two first lead wire placement slots 121, and the first lead wire placement slots 121 are evenly and equidistantly arranged.

[0053] With this setting, multiple lead wires 40 can be placed at the same time, and the bending operation of multiple lead wires 40 can be completed with a single press, which greatly improves the processing efficiency of lead wire bending and is suitable for mass production.

[0054] Specifically, each first lead wire placement slot 121 is evenly spaced, the lead wire 40 is placed at the same interval, and the bending reference is uniform, which effectively ensures that the bending position and spacing of each lead wire 40 are uniform, avoids the problem of uneven spacing due to manual placement, and improves product consistency.

[0055] In one embodiment, the top end of the bending plate 32 extends along its own length to form a fixing part 321. The fixing part 321 is provided with a second through hole that runs vertically through it. The limiting guide post 33 passes through the second through hole and is fixedly connected to the fixing hole 312 on the fixing seat 31. The top end of the limiting guide post 33 is provided with a limiting block 331. The limiting block 331 is located above the fixing part 321. A spring 332 is sleeved on the outer wall of the limiting guide post 33. The bottom end of the spring 332 abuts against the end face of the opening of the fixing hole 312, and the top end of the spring 332 abuts against the lower surface of the fixing part 321.

[0056] This setup offers several advantages: First, it allows the bending plate 32 to slide precisely vertically along the limiting guide post 33, effectively limiting its lateral and circumferential deviation and ensuring its linear lifting and lowering movement, thus guaranteeing precise bending of the lead wire 40. Second, it enables upper limit positioning of the bending plate 32, preventing it from detaching from the limiting guide post 33 during spring 332 pushing or lifting, thereby enhancing the safety and integrity of the overall assembly structure. Third, when the bending plate 32 presses down to bend the lead wire 40, the spring 332 stores energy under pressure. After the pressure is released, the spring 332's elastic rebound drives the bending plate 32 to automatically return to its original position, eliminating the need for manual lifting and resetting, simplifying operation, and increasing continuous work efficiency.

[0057] refer to Figure 4 As one implementation, it also includes a second limiting plate 314, the top end of which is fixedly connected to the lower surface of the fixed base 31, and the second limiting plate 314 has a wedge-shaped structure.

[0058] With this setting, during bending operations, the lead wire 40 can be pressed and limited from above in advance to prevent the area of ​​the lead wire 40 to be bent from tilting or arching upwards, thus avoiding displacement of the lead wire 40 under force and ensuring that the bending position is accurate and controllable.

[0059] refer to Figure 4 In one embodiment, the bottom end of the fixed base 31 is provided with a gripping part 313, which is operated by external force to drive the fixed base 31 to move.

[0060] With this setup, the operator can directly apply force by hand, easily moving and pressing down the fixed base 31 and the entire bending mechanism without the need for additional tools. The operation is simple and convenient, reducing the difficulty of the work. At the same time, the grip part 313 is easy for the hand to hold stably and apply force evenly, allowing for precise control of the pressing stroke and bending force. This avoids excessive force that could cause the lead wire 40 to break or become excessively deformed, thus improving the bending accuracy and yield rate.

[0061] refer to Figure 1 and Figure 6 In one embodiment, the base 10 is provided with a first connecting hole 13 in the horizontal direction, and the first limiting plate 20 is provided with a second connecting hole 21 corresponding to the first connecting hole 13. The first connecting hole 13 and the second connecting hole 21 are fixedly connected by a connector.

[0062] With this configuration, the overall structure is tightly assembled, preventing loosening or displacement during operation, ensuring the positioning accuracy of the first limit plate 20, and improving the overall structural stability of the device. Simultaneously, the first limit plate 20 can be quickly installed, disassembled, and replaced, facilitating later inspection and component maintenance, and reducing operating and maintenance costs.

[0063] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0064] The above description is merely an embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art.
