Description

Technical Field

[0001] The utility model relates to the technical field of copper-nickel wire stretching equipment, in particular to a copper-nickel wire stretching device. Background Art

[0002] The main chemical components of copper-nickel wire are nickel and copper, and its shape is wire-like, so it is called copper-nickel wire. During the production process of copper-nickel wire, it needs to be stretched, usually using a stretching device. The stretching device is widely used in machinery manufacturing, hardware processing, petrochemicals, plastics, bamboo and wood products, wires and cables and other industries.

[0003] The existing Chinese patent (publication number: CN221581494U) discloses a copper-nickel wire stretching device, which includes a support frame and a movable plate, wherein the support frame is internally provided with a partition and a lifting frame, a sliding plate is slidably provided on one side of the partition, a support block is provided on the top of the sliding plate, and a sleeve and a guide rod are respectively provided on the side close to the two support blocks, one end of the guide rod penetrates into the sleeve and slides with it, and a movable plate is provided on the outside of the sleeve and the guide rod, a fixed roller is provided on the top of the movable plate, a fixed sleeve is provided between the two support blocks, an air inlet pipe is provided at the center position of the fixed sleeve, and multiple air outlets are provided at one end of the air inlet pipe; the copper-nickel wire stretching device is easy to use and adjust, and can stretch copper-nickel wires of different lengths. The air outlet discharges air and cools the copper-nickel wire to prevent the heat generated during the stretching process from affecting the quality of the copper-nickel wire finished product.

[0004] The above-mentioned stretching device will generate a certain amount of heat during the stretching process. For this purpose, the copper-nickel wire can be cooled by generating a cooling airflow through an air pump. However, in the actual production process, copper-nickel wires of different thicknesses are often stretched, and copper-nickel wires of different thicknesses often generate different amounts of heat. Only dissipating heat through an air pump cannot produce different heat dissipation effects for copper-nickel wires of different thicknesses. For thinner copper-nickel wires, the cooling airflow generated by the air pump may be too strong, which may easily cause the copper-nickel wire to be subjected to unnecessary airflow impact during the cooling process, causing the position of the copper-nickel wire to shift, affecting the accuracy and stability of the stretching. Moreover, an excessively strong airflow may cause local overcooling on the surface of the thin copper-nickel wire, thereby causing uneven stress inside the copper-nickel wire. For thicker copper-nickel wires, the cooling airflow of a single intensity generated by the air pump is often difficult to meet its heat dissipation needs. Thicker copper-nickel wires generate more heat during the stretching process, and the existing cooling method cannot provide sufficient cooling capacity, which may cause the local temperature of the copper-nickel wire to be too high.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Please see the attached Figure 1 To the attached Figure 5 The utility model provides a technical solution: a copper-nickel wire stretching device, comprising a mounting base 1, a mounting frame 2 connected to the mounting base 1, and a connecting frame connected to the top of the mounting frame 2, including:

[0032] The limiting frames 301 are provided in at least two pieces and can be slid relative to or opposite to each other in the installation frame 2;

[0033] The transmission bolt 302 is threadedly connected to the limit frame 301. The bottom of the transmission bolt 302 is rotatably connected to a contact plate for fixing the copper-nickel wire;

[0034] The transmission screw 303 is rotatably connected in the connection frame and rotates synchronously with the rotation of the transmission bolt 302. A wedge block 304 is threadedly connected to the transmission screw 303. A sliding frame 305 is slidably provided in the connection frame and is rotatably connected to a driven gear 307.

[0035] The transmission gears 306 are provided in a plurality and are rotatably arranged in the sliding frame 305. They are evenly spaced in a linear array along the length of the sliding frame 305, and their inner diameters increase successively. When the wedge block 304 gradually slides toward the sliding frame 305 along the length of the connecting frame, the sliding frame 305 can slide along the width of the connecting frame to drive the transmission gears 306 and the driven gear 307 to engage with each other.

[0036] The second telescopic rod 403 is connected to the sliding frame 305 and is used to drive the multiple transmission gears 306 to mesh with the driven gears 307 in sequence;

[0037] The heat dissipation fan blade 308 is rotatably connected to one side of the connection frame to generate heat dissipation airflow

[0038] A driving member for driving the transmission gear 306 to rotate is provided in the sliding frame 305;

[0039] An infrared distance measuring switch is provided at one end of the wedge block 304 , and the infrared distance measuring switch is used to control the second telescopic rod 403 .

[0040] It should be noted that a driving screw is rotatably connected inside the mounting base 1, the limit frame 301 is threadedly connected to the driving screw, a driving motor that drives the driving screw to rotate is connected to one side of the mounting base 1, and a ventilation hole is opened on one side of the mounting base 1.

[0041] In the specific implementation, the transmission bolt 302 is rotated. Since the bottom of the transmission bolt 302 is connected to the contact plate, as the transmission bolt 302 rotates, the contact plate moves downward to fix the copper-nickel wire. The two limit frames 301 are adjusted to slide back to each other by the driving screw, thereby stretching the copper-nickel wire. In the process of rotating the transmission bolt 302 to fix the copper-nickel wire, if the copper-nickel wire is thicker, the transmission bolt 302 rotates a smaller number of times. At this time, the transmission screw 303 rotates a smaller number of times, and the wedge block 304 moves a smaller position, thereby pushing the sliding frame 305 to move a certain distance, and the inner diameter is larger. The large transmission gear 306 is meshed with the driven gear 307, and the speed of the heat dissipation fan blade 308 is accelerated, thereby improving the heat dissipation effect. Correspondingly, when the copper-nickel wire is thinner, the number of turns of the transmission bolt 302 is greater, and the wedge block 304 moves a greater position, thereby pushing the sliding frame 305 to move a certain distance. The transmission gear 306 with a smaller inner diameter is meshed with the driven gear 307, and the speed of the heat dissipation fan blade 308 is relatively slowed down to avoid the cooling airflow being too strong, which may easily cause the copper-nickel wire to be subjected to unnecessary airflow impact during the cooling process.

[0042] As for the second telescopic rod 403, it is convenient to use with the infrared ranging switch. During the sliding process of the wedge block 304, the extension of the second telescopic rod 403 can be controlled by the infrared ranging switch, so that the corresponding transmission gear 306 can engage with the driven gear 307.

[0043] refer to Figure 3 and Figure 4 The driving member includes a servo motor 401 connected to the sliding frame 305, the driving end of the servo motor 401 is connected to the first telescopic rod 402, the telescopic end of the first telescopic rod 402 is connected to the rotating shaft of the driving transmission gear 306, and the telescopic end of the second telescopic rod 403 is connected to the other end of the rotating shaft.

[0047] In specific implementation, the designed air pipe 12 is convenient for conveying the airflow generated by the heat dissipation fan blades 308 to the cooling tube 13. The copper-nickel wire can be cooled through the air outlet opened on the cooling tube 13, and the spiral distribution design facilitates improving the uniformity of heat dissipation.

[0048] See Figure 2 One side of the sliding frame 305 is connected to a return spring 11, and the other end of the return spring 11 is connected to the connecting frame.

[0049] In specific implementation, the designed return spring 11 facilitates the sliding frame 305 to return to its original position.

[0052] See Figure 4 and Figure 5 The top of the wedge block 304 is connected to a guide column 10, and the guide column 10 is slidably connected to the connecting frame.

[0053] In specific implementation, the designed guide column 10 is convenient for limiting and guiding the sliding of the wedge block 304, further improving the stability of the wedge block 304 during the sliding process.
