Description

Technical Field

[0001] This utility model relates to the field of chain production technology, specifically a chain cutting device. Background Technology

[0002] In the chain manufacturing process, cutting is mainly used to cut continuous chain materials (such as metal wires, steel strips, etc.) to a predetermined length to obtain chain link blanks of appropriate size. These blanks are then processed (such as stamping, bending, welding, etc.) and finally assembled into a complete chain.

[0003] Chinese patent CN215468540U discloses a chain cutting device, mainly comprising a cutting body, a vacuum cleaner housing, a chassis, a mounting bracket, chain clamps, chain slots, a slider, a cutting mechanism (cutting head housing, coolant device, adjusting dial, cutting shaft, cutting head, and air outlet pipe), a vacuum cleaner, a vacuum duct, heat dissipation holes, and a toolbox. This design uses chain slots and chain clamps to fix the chain, and the slider on the mounting bracket moves the cutting mechanism left and right. Combined with the sliding groove on the top of the cutting body, this allows the mounting bracket to move back and forth, achieving omnidirectional chain cutting. Simultaneously, the vacuum cleaner, vacuum duct, and vacuum holes absorb processing dust. However, this design cannot adjust the chain tension during its movement.

[0004] In view of the aforementioned technologies, a chain cutting device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

The first support plate 11 is welded and fixed to one side of the third support plate 13, and the second support plate 12 is welded and fixed to the other side of the third support plate 13. The end of the third support plate 13 near the cutting assembly 3 is designed with an arc surface structure, and a knife groove 130 is provided at the arc surface end of the third support plate 13.

The two sides of the blade 32 are slidably connected to the slide groove 140. The other end of the blade 32 extends into the blade groove 130 and abuts against the blade strip 33. The other end of the blade strip 33 is fixedly connected to the base 34 through a damper. The base 34 is fixedly mounted on the inner walls of both sides of the stand 14. The cylinders 31 in the cutting assembly 3 drive the blade 32 to move along the slide groove 140. With the blade strip 33, efficient cutting of the chain can be achieved. The base 34, through the connection of the damper, can buffer the impact force generated during cutting and extend the service life of the device.

[0027] A reinforcing frame plate 5 is fixedly installed on one end of the third support plate 13 near the cutting assembly 2. The reinforcing frame plate 5 further strengthens the structural strength of the device. A telescopic elastic abutment rod 51 and a connecting arm 52 are fixedly installed on the reinforcing frame plate 5. The telescopic elastic abutment rod 51 is located below the outer wall of the reinforcing frame plate 5 on the same side as the connecting arm 52. The telescopic elastic abutment rod 51 and the connecting arm 52 provide a stable installation position for other components. A stepper motor 521 is fixedly installed on the connecting arm 52. An L-shaped tension rod 522 for adjusting the chain tension is fixedly connected to the output shaft of the stepper motor 521. The L-shaped tension rod 522 is in point contact with the telescopic elastic abutment rod 51. The stepper motor 521 on the connecting arm 52 drives the L-shaped tension rod 522 to precisely adjust the chain tension, avoid the chain from being too loose or too tight, and ensure the stability of chain transmission and cutting accuracy.

[0028] The cutting assembly 2 includes a drive motor 21, a rotating roller 22, a triangular plate 23, an H-shaped flap 24, a rubber guide roller 25, a servo motor 26, a rotating shaft 27, and a toothed sprocket 28. The rotating roller 22 is fixedly connected to the output shaft of the drive motor 21. Both ends of the rotating roller 22 are rotatably connected to the first support plate 11 and the second support plate 12, respectively. The chain to be cut is wound on the rotating roller 22. The triangular plate 23 is symmetrically fixedly arranged on the third support plate 13. One end of the triangular plate 23 is movably connected to the H-shaped flap 24 via a shaft. The other end of the H-shaped flap 24 is movably connected to the rubber guide roller 25 for guiding the chain. The rotating shaft 27 is fixedly connected to the output shaft of the servo motor 26. A toothed sprocket 28 is fixedly connected to the rotating shaft 27 to drive the chain into the cutting assembly. The toothed sprocket 28 meshes with the chain. The drive motor 21 in the cutting assembly 2 drives... The rotating roller 22 rotates, driving the wound chain to move. At the same time, the servo motor 26 drives the toothed sprocket 28 on the rotating shaft 27 to push the chain forward, allowing the chain to smoothly enter the cutting area. The triangular plate 23 has an arc groove 230. The two ends of the rubber guide roller 25 are slidably connected to the arc groove 230 of the triangular plate 23. One end of the rubber guide roller 25 is connected and fixed to the triangular plate 23 through a limiting locking ring. The arc groove 230 on the triangular plate 23 provides sliding space for the rubber guide roller 25, which guides the chain. The H-shaped flip plate 24 is fixedly equipped with a chain guide rail 241. The guiding effect of the rubber guide roller 25, together with the chain guide rail 241 on the H-shaped flip plate 24, can ensure the smoothness and positional accuracy of the chain during transmission, thereby improving the efficiency and quality of the entire chain cutting process, reducing the scrap rate, and reducing maintenance costs.

[0029] Working Principle: First, the drive motor 21 starts, driving the rotating roller 22 to rotate, causing the chain to be cut, wound on the rotating roller 22, to begin moving. During the movement, the chain first passes through the L-shaped tension rod 522 and the rubber guide roller 25, and then enters the chain guide rail 241 on the H-shaped flip plate 24 under the guidance of the rubber guide roller 25. When the chain reaches the corresponding position, the stepper motor 521 starts working, driving the L-shaped tension rod 522 to rotate at a certain angle. During this process, the telescopic elastic abutment 51 forms point contact with the L-shaped tension rod 522. Its elastic characteristics can buffer and limit the rotation range of the L-shaped tension rod 522, preventing the L-shaped tension rod 522 from colliding with the reinforcing frame plate 5 due to excessive rotation. At the same time, the arc groove 230 on the triangular plate 23 allows the rubber guide roller 25 to slide within it. By adjusting the height of the rubber guide roller 25, in coordination with the rotation of the L-shaped tension rod 522, the tension of the chain is precisely adjusted, ensuring the stability of chain transmission and the uniformity of tension. In addition, the servo motor 26 drives the rotating shaft 27 to rotate, which in turn drives the toothed sprocket 28 to rotate. Since the toothed sprocket 28 meshes with the chain, it pushes the chain towards the cutting assembly 3. When the chain reaches the predetermined cutting position, the cylinder 31 starts to operate, pushing the blade 32 to slide along the slide groove 140 of the bracket 14. The blade 32 enters the blade groove 130 and cuts the chain. Throughout the operation, the chain guide rail 241 on the H-shaped flip plate 24 provides stable support and guidance for the chain conveying, ensuring that the chain can pass through the cutting device smoothly and accurately. The coordinated cooperation between the various components ensures the efficiency and accuracy of the chain cutting operation.
