Description

Technical Field

[0002] Thread rolling machines are professional screw production equipment. They are lightweight, flexible, efficient, and have advantages that other similar equipment cannot replace. They avoid the limitations of lathes, drilling machines, or manual tapping, saving time and effort, reducing the risk of thread damage, and preventing tap breakage.

[0052] like Figures 1-4 As shown, a high-speed automatic yarn rolling machine according to an embodiment of the present disclosure is illustrated, including an inclined frame 1, a lower yarn rolling plate 2 fixedly connected to the inclined frame 1, and further including a lifting frame 3, an upper yarn rolling plate 4, a limiting rod 5 and a lifting mechanism. The lower yarn rolling plate 2 is fixedly connected to the top of the inclined frame 1 in an inclined state, and the lifting frame 3 is set on the top of the lower yarn rolling plate 2 through a guide mechanism.

[0053] Multiple upper thread rolling plates 4 are provided, and the multiple upper thread rolling plates 4 are mounted on the lifting frame 3 through a transmission mechanism for driving the multiple upper thread rolling plates 4 to move on the lower thread rolling plate 2. The transmission mechanism includes: a transmission shaft 6, a transmission belt 7, a drive motor 8, and a support assembly. Multiple transmission shafts 6 are provided, and all of the multiple transmission shafts 6 are rotatably connected inside the lifting frame 3. The transmission belt 7 is driven and connected between the multiple transmission shafts 6. The multiple upper thread rolling plates 4 are fixedly connected to the transmission belt 7. The drive motor 8 is mounted on the lifting frame 3, and the output end of the drive motor 8 passes through the lifting frame 3 and is fixedly connected to one of the transmission shafts 6. The support assembly is located inside the lifting frame 3 for supporting the bottom position of the transmission belt 7. The support assembly includes: a support plate 9 and a reinforcing plate 10. The support plate 9 is fixedly connected inside the lifting frame 3, and the bottom end of the support plate 9 contacts the transmission belt 7. Multiple reinforcing plates 10 are provided, and the bottom ends of the multiple reinforcing plates 10 are all fixedly connected to the support plate 9. One side of the multiple reinforcing plates 10 is fixedly connected to the lifting frame 3.

[0054] The drive motor 8 drives one of the transmission shafts 6 to rotate, and the transmission belt 7 drives multiple transmission shafts 6 to drive multiple upper thread rolling plates 4. This allows the multiple upper thread rolling plates 4 to continuously roll the blank on the lower thread rolling plate 2. During the thread rolling process, the reinforcing plate 10 and the support plate 9 support the transmission belt 7 and the upper thread rolling plates 4, thereby increasing the stability of the upper thread rolling plates 4 during the thread rolling process.

[0055] Two limit rods 5 are provided, and the two limit rods 5 are set in the inclined frame 1 through an adjustment mechanism. They are used to limit the thread rolling of the bolt blank. The adjustment mechanism includes: a linkage plate 11, a U-shaped frame 12, and a drive assembly. Two linkage plates 11 are provided, and the two linkage plates 11 are set in the inclined frame 1 through a sliding assembly. A U-shaped frame 12 is fixedly connected to each of the two linkage plates 11, and a limit rod 5 is fixedly connected to each U-shaped frame 12. The drive assembly is set in the inclined frame 1 and is used to drive the two linkage plates 11 to move relative to each other. The drive assembly includes: a bidirectional screw 13 and a first motor 14. Two mounting plates 2 are fixedly connected in the inclined frame 1. 1. A bidirectional screw 13 is rotatably connected to two mounting plates 21 and is rotatably connected to the inclined support 1. Two linkage plates 11 are provided with screw holes, and the bidirectional screw 13 is threaded into the two screw holes. A first motor 14 is installed in the inclined support 1. The output end of the first motor 14 is axially fixedly connected to one end of the bidirectional screw 13. The sliding assembly includes: a fixed plate 15 and a slide rod 16. There are two fixed plates 15, and both fixed plates 15 are fixedly connected to the inclined support 1. The slide rod 16 is fixedly connected between the two fixed plates 15. Both linkage plates 11 are provided with sliding holes, and the slide rod 16 is slidably connected into the two sliding holes.

[0056] The first motor 14 drives the bidirectional screw 13 to rotate. When the bidirectional screw 13 rotates, it drives the two linkage plates 11 to move, thereby driving the U-shaped frame 12 and the two limit rods 5 to move relative to each other, thereby limiting the blank during the thread rolling process and preventing the blank from deviating.

[0057] The lifting mechanism is set on the lower thread rolling plate 2 and is used to drive the lifting frame 3 to move up and down. The lifting mechanism includes: force block 17 and first electric cylinder 18. There are two force blocks 17, and both force blocks 17 are fixedly connected to the lifting frame 3. There are two first electric cylinders 18, and both first electric cylinders 18 are installed on the lower thread rolling plate 2. The output ends of the two first electric cylinders 18 are fixedly connected to the two force blocks 17 respectively.

[0058] The first electric cylinder 18 drives the force block 17 and the lifting frame 3 to move up and down, thereby adjusting the distance between the upper thread rolling plate 4 and the lower thread rolling plate 2, which facilitates the thread rolling operation of blanks of different specifications.

[0059] The guiding mechanism includes: guide block 19 and guide rod 20. There are multiple guide blocks 19, and multiple guide blocks 19 are fixedly connected to the lifting frame 3. Each guide block 19 is slidably connected to a guide rod 20, and multiple guide rods 20 are fixedly connected to the lower thread rolling plate 2.

[0060] The guide block 19 slides on the guide rod 20, thereby supporting the lifting frame 3 to move stably up and down.

[0061] Working principle: When the billet needs to be threaded, the first electric cylinder 18 drives the force block 17 and the lifting frame 3 to move up and down, thereby adjusting the distance between the upper thread rolling plate 4 and the lower thread rolling plate 2. Then, the first motor 14 drives the bidirectional screw 13 to rotate. When the bidirectional screw 13 rotates, it drives the two linkage plates 11 to move, thereby driving the U-shaped frame 12 and the two limit rods 5 to move relative to each other. After the distance between the two limit rods 5 is adjusted, a large amount of billet is neatly arranged between the two limit rods 5. The drive motor 8 drives one of the transmission shafts 6 to rotate, and the transmission belt 7 drives multiple transmission shafts 6 to drive multiple upper thread rolling plates 4. This allows the multiple upper thread rolling plates 4 to continuously roll the blank on the lower thread rolling plate 2. During the thread rolling process, the reinforcing plate 10 and the support plate 9 support the transmission belt 7 and the upper thread rolling plates 4, thereby increasing the stability of the upper thread rolling plates 4 during the thread rolling process. During this process, the operator continuously puts in new blanks to perform continuous thread rolling operations.
