Technical Field

[0001] The present invention relates to the technical field of ductile iron cutting, and specifically relates to a continuous ductile iron cutting device. Background Art

[0002] In the technical field of ductile iron cutting, when the existing cutting equipment cuts pipe materials, a fixed method of two-point clamping is generally adopted. This fixed method has obvious defects, resulting in poor stability of the pipe materials during the cutting process, easy occurrence of misalignment phenomenon, and further causing damage to the pipe materials during cutting, which not only affects the cutting quality but also reduces the working efficiency of the cutting equipment.

[0014] Beneficial effects:

[0015] 1. The present invention performs multi-point clamping and fixing of the pipe material through the material feeding assembly and the clamping assembly. The three clamping plates in the clamping assembly are synchronously moved through the worm and worm gear transmission structure to realize three-point clamping of the pipe material. The clamping plates in the material feeding assembly are driven by the second cylinder to clamp the rear end of the pipe material. The front and rear multi-point clamping method significantly improves the stability of the pipe material during cutting, effectively prevents the pipe material from being strung together and damaged during cutting, and ensures the cutting accuracy and quality.

[0016] 2. The rotating disk in the ring cutting device is driven by the first motor to mesh and rotate with the driven gear ring, driving the cutting machine to rotate around the pipe material, cooperating with the feeding movement of the first cylinder to achieve 360-degree rotational cutting of the pipe material, ensuring all-round and uniform cutting of the material, avoiding the problems of uneven incision and incomplete cutting that may occur in traditional unilateral cutting, and improving the consistency and reliability of the cutting effect.

[0017] 3. The material feeding assembly drives the lead screw to rotate through the third motor, driving the movable plate and the clamping plate to move linearly along the guide rod, which can accurately control the feeding amount of the pipe material. After completing a cutting, the clamping assembly can be released, the material can be driven to feed and re-clamped without stopping, so as to achieve continuous feeding and cutting, which greatly reduces the auxiliary time and significantly improves the automation degree and production efficiency of the equipment.

[0018] 4. The V-shaped plate in the material loading assembly can be adjusted in height through the linkage of the electric push rod and the support rod. The receiving position can be flexibly adjusted according to the length and weight of the cutting material. The rotating roller on the V-shaped plate facilitates the sliding transfer of the material. At the same time, the cooperation between the lifting rod and the lifting cylinder and the buffering effect of the support rod can effectively avoid the impact damage caused by the sudden fall of the material after cutting, reduce material loss, and improve the practicality and safety of the equipment.

[0019] 5. The driving gear and the driven gear ring in the ring cutting device adopt a bevel gear structure, which realizes the power transmission in the vertical direction and reduces the space occupied by the equipment; the threaded disk and the moving block of the clamping assembly are driven by threaded engagement, and the limiting effect of the guide groove is cooperated to ensure the smooth movement and precise positioning of the clamping plate; the clamping plate of the material feeding assembly is provided with a V-groove, which fits closely with the surface of the pipe material, enhancing the clamping force and transmission stability; the dovetail groove and dovetail block structure of the material loading assembly ensure the linearity and reliability of the driving plate movement. The overall structural design is compact and the transmission is efficient, which ensures the long-term stable operation of the equipment.

[0020] In summary, the present invention uses a material feeding component and a clamping component to perform multi-point clamping and fixing on the pipe material, thereby improving the stability during pipe material cutting, preventing the pipe material from shifting and being damaged during cutting. The pipe material is rotationally cut by a ring cutting device, enabling the material to be cut in all directions.

[0030] In this embodiment, it is further set that the clamping assembly includes a blocking plate 13. The blocking plate 13 is fixedly installed in the inner cavity and on one side of the ring cutting device. Three identically structured guide grooves 14 are formed in the blocking plate 13. A moving block 15 is slidably installed in the guide groove 14. One end of the moving block 15 penetrates through the inner cavity and is located inside the clamping cylinder 2. A clamping plate 16 is fixedly installed at one end of the moving block 15. A threaded groove is formed in the side wall surface of the moving block 15. A threaded disk 17 is rotatably installed in the inner cavity and on one side of the moving block 15. The threaded disk 17 is in meshing connection with the moving block 15. A worm gear 18 is fixedly installed on the side wall surface of the threaded disk 17. A second motor 19 is fixedly installed on the outer wall surface of the clamping cylinder 2.

The other end of the worm 20 is in meshing connection with the inner wall surface of the inner cavity. The worm 20 is in meshing connection with the worm gear 18.

[0031] When the second motor 19 is started, the driving end of the second motor 19 drives the worm 20 to rotate. The worm 20 drives the worm gear 18 to rotate. The worm gear 18 drives the threaded disk 17 to rotate. Since the moving block 15 is in meshing connection with the threaded disk 17 through the threaded groove, when the threaded disk 17 rotates, it has a driving effect on the moving block 15. At this time, the moving block 15 moves along the path of the guide groove 14, so that the moving block 15 pushes the clamping plate 16 to clamp and fix the material at three points.

[0032] In this embodiment, it is further set that the material feeding component includes a bearing ring 21, the bearing ring 21 is fixedly installed on the base 1 and is located on one side of the clamping cylinder 2. A pair of boxes 22 are fixedly installed between the bearing ring 21 and the clamping cylinder 2. A pair of guide rods 23 are fixedly installed between the bearing ring 21 and the clamping cylinder 2 and on one side of the boxes 22. A moving plate 24 is slidably installed between the guide rods 23. A pair of third motors 25 are fixedly installed on the side wall surface of the bearing ring 21. The driving end of the third motor 25 penetrates through the bearing ring 21 and the box 22 and is fixedly installed with a lead screw 26.

The displacement block 27 is meshed and connected to the lead screw 26. An opening is formed on the lower wall surface of the box 22. The displacement block 27 penetrates through the opening and is connected to the moving plate 24. An installation groove is formed on the moving plate 24. A second cylinder 28 is fixedly installed in the installation groove. A clamping plate 29 is fixedly installed on the moving end of the second cylinder 28.

[0033] Start the second cylinder 28. The second cylinder 28 pushes the clamping plate 29 to initially clamp and fix the material. At this time, start the third motor 25. The driving end of the third motor 25 drives the lead screw 26 to rotate. Since the displacement block 27 is meshed and connected to the lead screw 26, when the lead screw 26 rotates, it has a driving effect on the displacement block 27. The displacement block 27 moves along the opening path, and thus the clamping plate 29 drives the material to perform a feeding movement.

[0034] In this embodiment, it is further set that the clamping plate 29 is provided with a V-shaped groove.

[0035] In this embodiment, it is further set that the blanking and bearing component includes a V-shaped plate 30. Four corners of the lower wall surface of the V-shaped plate 30 are respectively fixedly installed with lifting rods 31. Lifting cylinders 32 are respectively fixedly installed on the base 1 and below the lifting rods 31. The lifting rods 31 are inserted into the lifting cylinders 32. A pair of dovetail grooves 33 are formed on the base 1 and below the V-shaped plate 30. A pair of dovetail blocks 34 are slidably installed in the dovetail grooves 33. A driving plate 35 is fixedly installed between the dovetail blocks 34. A pair of support rods 36 are hingedly connected to the upper wall surface of the driving plate 35. The support rods 36 are hingedly connected to the lower wall surface of the V-shaped plate 30. A pair of electric push rods 37 are fixedly installed on the base 1. The electric push rods 37 are connected to the driving plate 35. A plurality of rotating rollers 38 are rotatably installed on the upper wall surface of the V-shaped plate 30.

[0036] Start the electric push rod 37. The telescopic end of the electric push rod 37 pushes the driving plate 35. Under the action of the dovetail block 34, the driving plate 35 moves along the path of the dovetail groove 33. At this time, the driving plates 35 push towards each other, and the driving plate 35 pushes the support rod 36 to perform a supporting movement, so that the support rod 36 pushes the V-shaped plate 30 for height adjustment. The V-shaped plate 30 drives the lifting rod 31 to move out of the lifting cylinder 32. Adjusting the height of the V-shaped plate 30 is convenient for receiving materials. The material can be discharged and moved through the rotating roller 38.

[0037] The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0038] Pass the cylindrical material through the bearing ring 21 and the clamping cylinder 2, so that the length end of the material to be cut is exposed outside the clamping cylinder 2. Start the second motor 19. The driving end of the second motor 19 drives the worm 20 to rotate. The worm 20 drives the worm gear 18 to rotate. The worm gear 18 drives the threaded disk 17 to rotate. Since the moving block 15 is meshed with the threaded disk 17 through the threaded groove, when the threaded disk 17 rotates, it has a driving effect on the moving block 15. At this time, the moving block 15 moves along the path of the guide groove 14, so that the moving block 15 pushes the clamping plate 16 to clamp and fix the material at three points. Start the second cylinder 28. The second cylinder 28 pushes the clamping plate 29 to clamp and fix the material preliminarily. Start the electric push rod 37. The telescopic end of the electric push rod 37 pushes the driving plate 35. Under the action of the dovetail block 34, the driving plate 35 moves along the path of the dovetail groove 33. At this time, the driving plates 35 push towards each other, and the driving plate 35 pushes the support rod 36 to perform a supporting movement, so that the support rod 36 pushes the V-shaped plate 30 for height adjustment. The V-shaped plate 30 drives the lifting rod 31 to move out of the lifting cylinder 32. Adjusting the height of the V-shaped plate 30 is convenient for receiving materials. Start the cutting machine 7 to make the cutting machine 7 rotate idly. Start the first cylinder 6. The first cylinder 6 pushes the cutting machine 7 to feed, so that the cutting machine 7 cuts the material. At this time, start the first motor 9. The driving end of the first motor 9 drives the driving gear 10 to rotate. The driving gear 10 is meshed with the driven gear ring. When the driving gear 10 rotates, it drives the driven gear ring 8. The driven gear ring 8 drives the rotating disk 3 to rotate, so that the cutting machine 7 rotates, and the cutting machine 7 performs a circumferential cutting process on the material. When continuous cutting is required, release the clamping assembly. At this time, start the third motor 25. The driving end of the third motor 25 drives the lead screw 26 to rotate. Since the displacement block 27 is meshed with the lead screw 26, when the lead screw 26 rotates, it has a driving effect on the displacement block 27. The displacement block 27 moves along the opening path, so that the clamping plate 29 drives the material to feed and move. At this time, start the second motor 19 again to make the clamping plate 16 clamp the material again, and then the circumferential cutting assembly cuts the material again to realize the continuous cutting process.
