Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] like Figures 1 to 6 As shown, a bending and cutting device for a wire bending forming machine includes a bending mechanism and a cutting mechanism.

[0029] The bending mechanism includes a first mounting base 10, a turntable sleeve 11, a bending turntable 12, and a turntable drive motor 13. The turntable sleeve 11 is vertically rotatably connected to the first mounting base 10. The bending turntable 12 is located on the top of the turntable sleeve 11. The bending turntable 12 is provided with a retractable bending column 14. A turntable gear 111 is sleeved on the outer side of the turntable sleeve 11. The turntable drive motor 13 is located on the first mounting base 10 and is located on one side of the turntable sleeve 11. The output shaft end of the turntable drive motor 13 is meshed with the turntable gear 111 through a drive gear 131.

[0030] The cutting mechanism includes a second mounting base 20, an inner mold rod 21, a telescopic rod 22, and a telescopic rod 22 driving mechanism. The second mounting base 20 is vertically installed at the bottom of the first mounting base 10. The inner mold rod 21 passes through the turntable bushing 11. The top of the inner mold rod 21 is provided with a cutting upper mold 211 protruding from the center of the bending turntable 12. The inside of the cutting upper mold 211 is provided with a wire hole 212. The telescopic rod 22 slides through the inside of the inner mold rod 21. The top of the telescopic rod 22 is provided with a cutting blade 221 located inside the cutting upper mold 211. The telescopic rod 22 driving mechanism is located at the bottom of the second mounting base 20 and is used to drive the telescopic rod 22 and drive the cutting blade 221 to move up and down.

[0031] In practice, the straightened wire enters through the wire hole 212 of the upper die 211 of the cutter. The turntable drive motor 13 is connected to the turntable gear 111 on the outside of the turntable bushing 11 through the drive gear 131, driving the bending turntable 12 to rotate on the first mounting base 10. The wire is bent with high precision through the telescopic bending column 14. When the wire is processed to the preset length, the telescopic rod 22 drive mechanism drives the cutter 221 at the top of the telescopic rod 22 to cut the wire passing through the wire hole 212 in the upper die 211 of the cutter at high speed, completing the processing of a wire product.

[0032] Both the drive gear 131 and the turntable gear 111 are high-precision ground gears to ensure stable and accurate bending transmission. The turntable drive motor 13 is a servo motor. Under the control of the CNC system, the servo motor can accurately control key parameters such as bending angle and position to meet the bending requirements of various complex-shaped products.

[0033] In this embodiment, a telescopic cylinder 15 connected to the bending column 14 is provided at the bottom of the bending turntable 12. This telescopic cylinder 15 is a high-speed cylinder, which greatly improves bending efficiency while ensuring bending accuracy, thus meeting standard production speed.

[0034] In this embodiment, the bending column 14 is detachably mounted on the bending turntable 12, and bending columns 14 of different sizes and shapes can be replaced to meet the bending requirements of various complex-shaped products.

[0035] In this embodiment, a bearing mounting seat 16 is sleeved on the outer periphery of the bending turntable 12.

[0036] In practice, the bending turntable 12 is fixed to the platform plate of the machine body via the bearing mounting seat 16. The upper end of the first mounting seat 10 can be fixed to the bottom of the platform plate.

[0037] In this embodiment, the telescopic rod 22 driving mechanism includes a hinged link structure 23 and a telescopic rod drive motor 24. The hinged link structure 23 is vertically disposed on the second mounting base 20, and the upper end of the hinged link structure 23 is fixedly connected to the lower end of the telescopic rod 22. The telescopic rod drive motor 24 is horizontally and vertically disposed at the bottom of the second mounting base 20. The shaft end of the telescopic rod drive motor 24 is provided with a connecting cam 241, and the shaft end of the connecting cam 241 is connected to the lower end of the hinged link structure 23 through a bearing.

[0038] The articulated link structure 23 includes an upper link 231 and a lower link 232 that are articulated together. The upper link 231 is connected to the telescopic rod 22, and the lower link 232 is connected to the connecting cam 241.

[0039] In practical implementation, the wire cutting method adopts a cam-linkage structure, which efficiently converts the cam rotational motion into the linkage linear motion, driving the telescopic rod 22 to move up and down reciprocally within the inner mold rod 21. This causes the cutter 221 at the upper end of the telescopic rod 22 to work with the upper die 211 to cut the wire passing through the wire hole 212, achieving fast and accurate cutting and greatly improving production speed.

[0040] In this embodiment, a guide rail slider 25 connected to the inner side of the second mounting base 20 is provided on one side of the upper connecting rod 231, which can improve the movement stability between the upper connecting rod 231 and the lower connecting rod 232, and ensure that the cutter 221 cooperates with the upper die 211 to accurately cut the wire.

[0041] In this embodiment, a cutting blade mounting hole 213 is vertically provided on the cutting blade 221 mold. The cutting blade mounting hole 213 is connected to the wire passage hole 212. The cutting blade 221 is telescopically and slidably installed in the cutting blade mounting hole 213 through the telescopic rod 22, thereby forming an inner cutting blade 221 mold structure.

[0042] The bending and cutting device of the wire bending forming machine provided by this utility model integrates the bending mechanism and the cutting mechanism into one design compared with the prior art. The inner mold rod 21 passes through the turntable bushing 11, and the upper cutting mold 211 protrudes from the center of the bending turntable 12 at the top of the inner mold rod 21. The telescopic rod 22 slides through the inner mold rod 21. The telescopic rod 22 is connected to the telescopic rod 22 through the telescopic rod 22 drive mechanism, which drives the cutting blade 221 to move up and down. It cooperates with the upper cutting mold 211 to form the inner cutting blade 221 mold structure, which can quickly cut the wire, effectively improve the cutting efficiency, increase the production speed, and the overall design structure is compact, which improves the machine body space.

[0043] Where there is no conflict, the above embodiments and features can be combined with each other.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
