Description

Technical Field

[0001] This utility model relates to the field of electrode wire manufacturing technology, and in particular to an electrode wire hot melt forming device. Background Technology

[0002] As precision components within precision instruments, the bending and pressing of electrode wires significantly impacts the quality and performance of these instruments. Existing equipment and processes typically require specialized bending tools and molds for bending electrode wires. Before bending, the bending position and angle must be precisely measured and marked according to design requirements, which introduces measurement errors. Uneven bending angles and even damage at the bending points can also occur during the bending process. The pressing methods used also struggle to ensure accuracy, potentially resulting in scratches, dents, or other surface defects on the electrode wire, affecting its appearance and performance. Since electrode wires are usually made of metal or other materials, excessive bending or pressing can cause material deformation, affecting the wire's mechanical strength and conductivity.

[0003] Currently, there is no good equipment on the market for producing electrode wire bending and pressing products that can achieve stable bending angles and maintain the appearance after pressing. Therefore, there is an urgent need to develop reliable and stable new production equipment to ensure the mass production of new electrode wire bending and pressing products that meet customers' technical and quality requirements.

Detailed Implementation

[0033] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0036] In the following embodiments, unless otherwise specified, the functional components or structures are conventional components or structures used in the art to achieve the corresponding functions.

[0037] Example 1:

[0038] like Figures 1-6 The diagram shows an electrode wire hot-melt forming device, comprising: a circular indexing plate 7 for placing the electrode wire to be formed; a positioning member 8 disposed on the circular indexing plate 7 for fixing the electrode wire to be formed; and a feeding mechanism 1, a bending forming mechanism 2, a high-frequency heating mechanism 3, a hydraulic forming mechanism 4, a vision inspection mechanism 5, and a unloading mechanism 6 arranged sequentially on the outer periphery of the circular indexing plate 7 along the rotation direction of the circular indexing plate 7. The feeding mechanism 1 places the electrode wire to be formed into the positioning groove on the circular indexing plate 7; the bending forming mechanism 2 bends the electrode wire to be formed to a set curvature to obtain a bent electrode wire; the high-frequency heating mechanism 3 uses high-frequency hot-melt heating to bend the electrode wire to obtain a hot-melt electrode wire; the hydraulic forming mechanism 4 uses hydraulic stamping to form the hot-melt electrode wire to obtain a formed electrode wire; the vision inspection mechanism 5 detects the size, shape, and surface quality of the formed electrode wire; and the unloading mechanism 6 clamps and removes the qualified formed electrode wire.

[0039] In this technical solution, the positioning component 8 used to fix the electrode wire to be formed is accurately transferred to the feeding mechanism, bending and forming mechanism, high-frequency heating mechanism, hydraulic forming mechanism, visual inspection mechanism and unloading mechanism through the disc indexing plate 7, so as to strictly control every link of the electrode wire processing.

[0040] Taking molybdenum wire as an example, the diameter of the electrode wire to be formed can range from 0.15 to 0.5 mm. Using the device in this embodiment, the forming accuracy can reach 0.005 mm. Although molybdenum wire has a certain degree of toughness, it is prone to localized stress concentration when the bending angle is too large, the speed is too fast, or the stress is uneven, exceeding its bearing limit and leading to breakage. Furthermore, due to the elastic properties of molybdenum wire, if the springback is not fully considered during bending, the bent wire may spring back, resulting in a final bending angle that does not match the expected value. In addition, friction between the molybdenum wire and various mechanisms during bending may cause surface scratches, wear, or even micro-cracks. These surface defects can affect the service life and performance of the molybdenum wire. To avoid the above problems, this embodiment provides the following specific solution:

[0041] An electrode wire hot-melt forming apparatus includes: a circular indexing plate 7 for placing a molybdenum wire to be formed; a positioning component 8 disposed on the circular indexing plate 7 for fixing the molybdenum wire to be formed; and a feeding mechanism 1, a bending forming mechanism 2, a high-frequency heating mechanism 3, a hydraulic forming mechanism 4, a vision inspection mechanism 5, and a unloading mechanism 6 arranged sequentially on the outer periphery of the circular indexing plate 7 along the rotation direction of the circular indexing plate 7. The feeding mechanism 1 is used to place the molybdenum wire to be formed into a positioning groove on the circular indexing plate 7; the bending forming mechanism 2 is used to bend the molybdenum wire to a set curvature to obtain a bent molybdenum wire; the high-frequency heating mechanism 3 is used to bend the molybdenum wire using high-frequency hot-melt heating to obtain a hot-melt molybdenum wire; the hydraulic forming mechanism 4 is used to hydraulically punch the hot-melt molybdenum wire to obtain a formed molybdenum wire; the vision inspection mechanism 5 is used to inspect the size, shape, and surface quality of the formed molybdenum wire; and the unloading mechanism 6 is used to clamp and separate the qualified formed molybdenum wire.

[0042] The rotary indexing plate 7 is equipped with several positioning components 8, including a support adjustment rod 801, a wire clamp 802 located at one end of the support adjustment rod 801 for fixing the molybdenum wire to be formed, and a limiting block 803 located at the other end of the support adjustment rod 802. Using the rotary indexing plate 7 to adjust the position and the positioning components 8 to fix the molybdenum wire to be formed prevents collisions and friction between the wire and other mechanisms, thus avoiding surface damage. It also enables precise and orderly material handling, feeding, precision bending, heating, stamping, inspection, and unloading, completing a single multi-process production of the molybdenum wire.

[0043] The feeding mechanism 1 includes a first robotic arm for transferring the molybdenum wire to be formed into a positioning component 8 on a rotary indexing plate 7, and a first gripper located at the end of the first robotic arm. During operation, the first gripper clamps the molybdenum wire to be formed, feeds it into the rotary indexing plate 7 through the first robotic arm, and fixes it with wire clamping pliers 802.

[0044] The bending and forming mechanism 2 includes a CNC servo motor 201, a rotary worktable 202 electrically connected to the CNC servo motor 201 and used for bending the molybdenum wire to be formed, and a lifting and fixing assembly 203 vertically disposed above the rotary worktable 202 for fixing the molybdenum wire to be formed. The lifting and fixing assembly 203 can be a lifting cylinder, with its movable end connected to a ejector pin, allowing the cylinder to descend so that the ejector pin presses down on the molybdenum wire to be formed on the rotary worktable 202. When the positioning component 8 rotates to the bending and forming mechanism 2, the rotary worktable 202, the lifting and fixing assembly 205, and the wire clamp 802 can work together to position and fix the molybdenum wire to be formed. The CNC servo motor 201 controls the rotary worktable 202 to rotate, resulting in a bent molybdenum wire with one end bent. The positioning and lifting assembly 203 is also equipped with a first camera 204 for monitoring the bending angle of the molybdenum wire.

[0045] The bending and forming mechanism is positioned and fixed in both horizontal and vertical directions, avoiding losses due to the rebound of the molybdenum wire during bending and improving the instability of the bending angle center. The rotation speed of the rotary table 202 is optimized by the CNC servo motor 201, reducing impact and vibration during movement, improving the smoothness and accuracy of bending, ensuring the rigidity and stability of the bending and forming mechanism, reducing backlash and elastic deformation during mechanical transmission, and saving costs.

[0046] The high-frequency heating mechanism 3 includes a heating tube 301 for hot-melting and bending the electrode wire, and a power supply connected to the heating tube 301. The heating tube 301 is L-shaped, and the power supply can be a high-frequency power supply. For example, the heating tube 301 can be a heating magnetic tube, which works by utilizing the principle of generating heat by current passing through a resistance wire. When current passes through the resistive material inside the magnetic tube, due to the existence of resistance, electrical energy is converted into heat energy, thereby raising the temperature of the heating magnetic tube and obtaining a hot-melt molybdenum wire.

[0047] The high-frequency heating mechanism controls the heating temperature by adjusting the output power of the high-frequency power supply. Higher power results in faster heating and a higher temperature rise. The power is dynamically adjusted based on a preset temperature value, and the heating time is set accordingly. By precisely controlling the heating time under known heating conditions, the desired temperature can be achieved, improving the stability of the molybdenum wire heating characteristics.

[0048] The hydraulic forming mechanism 4 includes a hydraulic cylinder 401 and a forming mold 402 located below the movable end of the hydraulic cylinder 401. The forming mold 402 is provided with several punching grooves, so that when the movable end of the hydraulic cylinder 401 moves downward to punch, the hot melt molybdenum wire can be formed into various shapes with the same outline as the punching grooves, thus obtaining the formed molybdenum wire.

[0049] The stamping process uses hydraulic control and is made of custom-made cemented carbide. The diameter and length of the electrode wire material can be freely selected according to its properties.

[0050] The visual inspection unit 5 includes a second camera 501, which performs quality inspection on the formed molybdenum wire to check for problems such as cracks, uneven deformation, and dimensional deviations. Electrode wires that do not meet the requirements must be corrected or reprocessed in a timely manner.

[0051] The unloading mechanism 6 includes a second robotic arm 601 for transferring shaped molybdenum wire, a second gripper 602 located at the end of the second robotic arm, and a storage groove 603. After the second gripper 602 picks up the shaped molybdenum wire, it is transferred to the storage groove 603 by the second robotic arm 601.

[0052] In this embodiment, a control system is also provided, which consists of a Xinje XD3-24T-E PLC and a Xinje 7-inch TG765-MT touch screen. The control system controls the operation of the above-mentioned mechanisms. The control system is not the main innovation of this utility model, so the control part will not be described here.

[0053] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
