[0002] Jumper wire forming machines are automated equipment used in fields such as electronics manufacturing. They are mainly used to process metal wires into jumper wires of specific shapes. They can automatically complete a series of processing steps such as wire feeding, cutting, and bending according to preset parameters to produce jumper wire products that meet the requirements. In the bending process, bending clamps are used to bend the metal wires to make them meet the processing requirements.

[0003] Existing bending chucks are widely used, but they can usually only bend metal wires of a fixed diameter. They are not convenient to replace. Using bending chucks with fixed bending grooves to bend metal wires that are too thick or too thin can easily lead to substandard quality. Therefore, a bending chuck that can adapt to various wire diameters is proposed to address the above problems. Utility Model Content

[0026] A bending chuck adaptable to various wire diameters includes a mounting frame 1. A symmetrically arranged fixed bearing 2 is installed inside the mounting frame 1. A symmetrically arranged first retaining strip 3 is fixedly connected to the inner side of the inner ring of the fixed bearing 2. A connecting pin 4, inserted into the inner side of the inner ring of the fixed bearing 2, is provided on the outer side of the first retaining strip 3. A handle 5 is fixedly connected to one end of the connecting pin 4. A retaining groove 6 is symmetrically formed on the outer side of the connecting pin 4. A chuck body 7 is located inside the mounting frame 1. A bending groove 8 is formed in the center of the outer side of the chuck body 7. A symmetrically arranged second retaining strip 9 is fixedly connected to the inner side of the chuck body 7. A positioning component 10 is symmetrically installed on the outer side of the mounting frame 1. Both the first retaining strip 3 and the second retaining strip 9 are located inside the retaining groove 6. The connecting pin 4 is inserted into the inner side of the chuck body 7. The positioning component 10 includes a fixing block 101 fixedly connected to the outer side of the mounting frame 1. A fixing frame 102 is slidably connected to the outer side of the fixing block 101. The bottom of the fixing frame 102 is located at both ends of the connecting pin 4. Two sets of symmetrically arranged retaining grooves are formed on the side of the fixing frame 102 away from the mounting frame 1. The positioning hole 103 has a threaded groove 104 on the side of the fixing block 101 away from the mounting frame 1. A bolt 105 is threadedly connected to the inner side of the threaded groove 104. A mounting hole plate 106 is provided on the outer side of the bolt 105. A symmetrically arranged positioning pin 107 is fixedly connected to the side of the mounting hole plate 106 near the mounting frame 1. The positioning holes 103 are arranged in pairs. The positioning pin 107 is inserted into the inner side of one set of positioning holes 103. The positioning is connected by a first retaining strip 3, a connecting pin 4, a handle 5, and a retaining groove 6. The chuck body 7, bending groove 8, second locking strip 9, and positioning assembly 10 are designed to be used to assemble metal wires of different diameters. When bending is required, the bolt 105 is unscrewed and the mounting plate 106 is removed. The fixing frame 102 is pulled upwards and fixed using the front mounting plate 106. The chuck body 7 is then removed by pulling the handle 5, allowing for the replacement of the chuck body 7 with different bending grooves 8 to accommodate metal wires of different diameters. This design makes the installation and replacement of the chuck body 7 convenient and improves work efficiency.

[0027] The bending groove 8 is symmetrically provided with mounting grooves 11 on the outside of the clamp body 7. A connecting block 12 is fixedly connected to the inside of the mounting groove 11. A rubber ring 13 is provided on the outside of the connecting block 12. A connecting groove 14 is provided on the inside of the rubber ring 13. The connecting block 12 is set inside the connecting groove 14 and is engaged with the connecting groove 14. Multiple connecting blocks 12 and connecting grooves 14 are provided. The connecting blocks 12 and connecting grooves 14 are distributed in a polar axis on the inside of the rubber ring 13. Through the provided mounting groove 11, connecting block 12, rubber ring 13 and connecting groove 14, when the device is in use, the outside of the rubber ring 13 is in close contact with the outside of the wire outlet of the jumper wire forming machine. When the metal wire is discharged, the components on the jumper wire forming machine drive the mounting frame 1 to move. At this time, the rubber ring 13 rolls on the outside of the wire outlet of the jumper wire forming machine. This design can ensure that the device is always in contact with the outside of the wire outlet of the jumper wire forming machine, thereby ensuring the stability of the metal wire bending.

[0028] Workflow: Before use, first fix the mounting frame 1 on the jumper wire forming machine. Then, install the corresponding chuck body 7 according to the wire diameter of the metal wire. Put the rubber ring 13 on the inner side of the mounting groove 11 on the chuck body 7, and insert the connecting block 12 into the inner side of the connecting groove 14 and engage with the connecting groove 14. Next, place the chuck body 7 inside the mounting frame 1, and align the first locking strip 3 and the second locking strip 9 horizontally. Pick up the handle 5 and insert the connecting pin 4 into the inner side of the inner ring of the fixed bearing 2 and the inner side of the chuck body 7 until the first locking strip 3 and the second locking strip 9 are both set inside the groove 6. Next, move the fixing frame 102 outside the fixing block 101 so that the bottom of the fixing frame 102 is set at both ends of the connecting pin 4. Then, place the mounting hole plate 106 on one side of the fixing frame 102, insert the positioning pin 107 into the positioning hole 103, and align the mounting hole plate 106 horizontally with the threaded groove 104. Finally, insert the bolt 105 into the mounting hole plate 106 and screw it into the inner side of the threaded groove 104. The device can be installed. When using the device, the outer side of the rubber ring 13 is tightly fitted to the outer side of the wire outlet of the jumper wire forming machine. When the metal wire is discharged, the components on the jumper wire forming machine drive the mounting frame 1 to move, causing the chuck body 7 and the connecting pin 4 to rotate inside the fixed bearing 2, thereby bending the metal wire. At this time, the rubber ring 13 rolls on the outer side of the wire outlet of the jumper wire forming machine. The design of the rubber ring 13 and its connecting components ensures that the device is always in contact with the outer side of the wire outlet of the jumper wire forming machine, thereby ensuring the stability of the metal wire bending. When it is necessary to bend metal wires of different diameters, the bolt 105 is unscrewed and the mounting plate 106 is removed. The fixed frame 102 is pulled upward and fixed with the front mounting plate 106. The handle 5 is pulled to remove the chuck body 7, and the chuck body 7 with different bending grooves 8 can be replaced to adapt to metal wires of different diameters. The design of the positioning component 10 and its connecting components makes the installation and replacement of the chuck body 7 convenient and improves work efficiency.
