Description

Technical Field

[0001] This invention relates to the field of ductile iron cutting technology, specifically to a continuous cutting device for ductile iron. Background Technology

[0002] In the field of ductile iron cutting technology, existing cutting equipment generally uses a two-point clamping method when cutting pipes. This method has significant drawbacks, resulting in poor stability of the pipe during cutting, making it prone to displacement and damage. This not only affects cutting quality but also reduces the efficiency of the cutting equipment. Furthermore, existing equipment typically struggles to achieve continuous feeding and cutting of pipes, requiring frequent stops to adjust the material position, further hindering production efficiency. Simultaneously, the lack of an effective buffer device for the cut material means that sudden drops can easily cause damage, increasing production costs and material loss. Therefore, a new type of ductile iron cutting equipment is needed that can improve pipe cutting stability, achieve continuous cutting, and effectively protect the cut material. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a continuous cutting device for ductile iron, which solves the technical problem that existing cutting devices only fix the pipe material by two-point clamping during use.

[0009] Preferably, the material feeding assembly includes a bearing ring, which is fixedly installed on the base and located on one side of the clamping cylinder.

A pair of guide rods are fixedly installed between the bearing ring and the clamping cylinder and on one side of the housings. A moving plate is slidably installed between the guide rods.

[0014] Beneficial effects:

[0015] 1. This invention uses a material feeding assembly and a clamping assembly to clamp and fix the pipe material at multiple points. The three clamping plates in the clamping assembly move synchronously through a worm gear and worm wheel transmission structure to achieve three-point clamping of the pipe material. The clamping plate in the material feeding assembly is driven by a second cylinder to clamp the rear end of the pipe material. The multi-point clamping method significantly improves the stability of the pipe material during cutting, effectively prevents pipe material displacement and cutting damage, and ensures cutting accuracy and quality.

[0016] 2. The rotating disk in the ring cutting device is driven by the first motor to rotate the active gear and the driven gear ring, which in turn drives the cutting machine to rotate around the pipe material. Combined with the feeding motion of the first cylinder, it realizes 360-degree rotational cutting of the pipe material, ensuring uniform cutting of the material from all directions. This avoids problems such as uneven cuts and incomplete cutting that may occur with traditional single-sided cutting, and improves the consistency and reliability of the cutting effect.

[0017] 3. The material feeding assembly is driven by a third motor to rotate the lead screw, which in turn drives the moving plate and clamping plate to move linearly along the guide rod. This allows for precise control of the feed amount of the tube material. After one cut is completed, the machine can release the clamping assembly, drive the material feeding, and re-clamp without stopping the machine, thus achieving continuous feeding and cutting. This significantly reduces auxiliary time and greatly improves the automation level and production efficiency of the equipment.

[0018] 4. The V-shaped plate in the feeding and bearing assembly is height-adjustable 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 material to be cut. 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, as well as the buffering effect of the support rod, effectively avoids the impact damage caused by the sudden drop of the material after cutting, reduces material loss, and improves the practicality and safety of the equipment.

[0019] 5. In the ring cutting device, the driving gear and driven gear ring adopt a bevel gear structure, realizing vertical power transmission and reducing the space occupied by the equipment; the threaded disc and moving block of the clamping component are driven by threaded meshing, and with the limiting effect of the guide groove, it ensures that the clamping plate moves smoothly and is positioned accurately; the clamping plate of the material feeding component has a V-groove, which fits tightly with the surface of the pipe, enhancing the clamping force and transmission stability; the dovetail groove and dovetail block structure of the unloading bearing component ensures the linearity and reliability of the drive plate movement. The overall structure is compact, the transmission is efficient, and it ensures the long-term stable operation of the equipment.

[0020] In summary, this invention uses a material feeding assembly and a clamping assembly to clamp and fix the pipe material at multiple points, thereby improving the stability of the pipe material during cutting and preventing the pipe material from shifting and being damaged during cutting. The ring cutting device performs rotational cutting on the pipe material, allowing the material to be cut from all directions. The material feeding assembly can continuously feed the material, thereby achieving continuous cutting. The unloading and bearing assembly can bear the cut material, preventing the material from falling suddenly and being damaged. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-8 The present invention provides a technical solution: a continuous cutting device for ductile iron, including a base 1, a clamping cylinder 2 fixedly installed on the base 1, the clamping cylinder 2 having an inner cavity, the side wall of the clamping cylinder 2 having an open structure, a ring cutting device provided on the side wall of the clamping cylinder 2, a clamping assembly provided inside the clamping cylinder 2 and on one side of the ring cutting device, a material feeding assembly provided on the other side wall of the clamping cylinder 2, and a material unloading and bearing assembly provided on the base 1 and on one side of the clamping cylinder 2.

[0032] The cylindrical material is passed through the material feeding assembly and the clamping cylinder 2. The rear end of the material is clamped and fixed by the material feeding assembly, and the front end of the material is clamped and fixed by the clamping assembly. The ring cutting assembly is activated to perform a circumferential cut on the front end exposed in the clamping cylinder 2. The cut material falls into the unloading support assembly, thus completing the unloading. During continuous cutting, the clamping assembly is released, and the cylindrical body is moved into the clamping cylinder 2 by the material feeding assembly and clamped and fixed again by the clamping assembly, thus performing the continuous cutting process.

[0033] In this embodiment, the girdling device includes a rotating disk 3, which is rotatably mounted on the side wall of the clamping cylinder 2 and located inside the inner cavity. One side of the rotating disk 3 is exposed outside the clamping cylinder 2, and a bearing plate 4 is fixedly mounted on one side of the rotating disk 3. A connecting plate 5 is fixedly mounted on the upper end of the bearing plate 4, and a first cylinder 6 is fixedly mounted on the lower wall of the connecting plate 5. A cutting machine 7 is fixedly mounted on the telescopic end of the first cylinder 6. The other side wall of the rotating disk 3 is located inside the inner cavity and a driven gear ring 8 is fixedly mounted thereon. A first motor 9 is fixedly mounted on the upper outer wall of the clamping cylinder 2. The driving end of the first motor 9 passes through the clamping cylinder 2 and a driving gear 10 is fixedly mounted thereon. The driving gear 10 meshes with the driven gear ring 8.

[0034] Start the cutting machine 7 to allow it to idle. Start the first cylinder 6, which pushes the cutting machine 7 to feed, thereby cutting the material. At this time, start the first motor 9. The drive end of the first motor 9 drives the drive gear 10 to rotate. The drive gear 10 meshes with the driven gear, thereby driving the driven gear ring 8 when the drive gear 10 rotates. The driven gear ring 8 drives the rotating disk 3 to rotate, thereby rotating the cutting machine 7 and performing a ring cutting process on the material.

[0035] In this embodiment, the driving gear 10 is configured as a bevel gear structure, and the driven gear ring 8 is configured as a bevel gear ring structure.

[0036] In this embodiment, a track 11 is fixedly installed on the outer wall of the clamping cylinder 2 and on one side of the first motor 9, and a slider 12 is fixedly installed on the lower wall of the connecting plate 5, and the slider 12 is slidably installed in the track 11.

[0037] In this embodiment, the clamping assembly includes a blocking plate 13, which is fixedly installed in the inner cavity and located on one side of the girdling device. The blocking plate 13 has three identical guide grooves 14. A moving block 15 is slidably installed in the guide grooves 14. One end of the moving block 15 passes through the inner cavity and is located in the clamping cylinder 2. A clamping plate 16 is fixedly installed at one end of the moving block 15. A threaded groove is opened on the side wall of the moving block 15. A threaded disc 17 is rotatably installed in the inner cavity and on one side of the moving block 15. The threaded disc 17 is meshed with the moving block 15. A worm gear 18 is fixedly installed on the side wall of the threaded disc 17. A second motor 19 is fixedly installed on the outer wall of the clamping cylinder 2. The driving end of the second motor 19 passes through the clamping cylinder 2 and a worm 20 is fixedly installed thereon. The other end of the worm 20 is meshed with the inner wall of the inner cavity. The worm 20 is meshed with the worm gear 18.

[0038] The second motor 19 is started, and the drive end of the second motor 19 drives the worm 20 to rotate. The worm 20 drives the worm wheel 18 to rotate, and the worm wheel 18 drives the threaded disc 17 to rotate. Since the moving block 15 is engaged with the threaded disc 17 through the threaded groove, the rotation of the threaded disc 17 drives the moving block 15. At this time, the moving block 15 moves along the path of the guide groove 14, thereby pushing the clamping plate 16 to clamp and fix the material at three points.

[0039] In this embodiment, the material feeding assembly includes a bearing ring 21, which is fixedly mounted on the base 1 and located on one side of the clamping cylinder 2. A pair of housings 22 are fixedly mounted between the bearing ring 21 and the clamping cylinder 2. A pair of guide rods 23 are fixedly mounted between the bearing ring 21 and the clamping cylinder 2 and on one side of the housings 22. A movable plate 24 is slidably mounted between the guide rods 23. A pair of third motors 25 are fixedly mounted on the side wall of the bearing ring 21, and the driving end of the third motor 25 passes through... A bearing ring 21 and a housing 22 are provided, and a lead screw 26 is fixedly installed thereon. The other end of the lead screw 26 is rotatably installed on the other side wall of the housing 22. A displacement block 27 is slidably installed inside the housing 22. The displacement block 27 is meshed with the lead screw 26. An opening is provided on the lower wall of the housing 22. The displacement block 27 passes through the opening and is connected to a moving plate 24. An installation groove is provided 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.

[0040] The second cylinder 28 is started, and the second cylinder 28 pushes the clamping plate 29 to initially clamp and fix the material. At this time, the third motor 25 is started, and the drive 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, the rotation of the lead screw 26 has a driving effect on the displacement block 27. The displacement block 27 moves along the opening path, thereby causing the clamping plate 29 to drive the material to move in a feeding motion.

[0041] In this embodiment, the clamping plate 29 is further configured to have a V-shaped groove.

[0042] In this embodiment, the unloading and bearing assembly includes a V-shaped plate 30. Lifting rods 31 are fixedly installed at the four corners of the lower wall of the V-shaped plate 30. Lifting cylinders 32 are fixedly installed on the base 1 below the lifting rods 31. The lifting rods 31 are inserted into the lifting cylinders 32. A pair of dovetail grooves 33 are provided on the base 1 below the V-shaped plate 30. A pair of dovetail blocks 34 are slidably installed in the dovetail grooves 33. A drive plate 35 is fixedly installed between the dovetail blocks 34. A pair of support rods 36 are hinged to the upper wall of the drive plate 35. The support rods 36 are hinged to the lower wall 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 drive plate 35. A plurality of rotating rollers 38 are rotatably installed on the upper wall of the V-shaped plate 30.

[0043] When the electric push rod 37 is activated, its telescopic end pushes the drive plate 35. Under the action of the dovetail block 34, the drive plate 35 moves along the path of the dovetail groove 33. At this time, the drive plates 35 push towards each other and push the support rod 36 to perform support movement, thereby causing the support rod 36 to push the V-shaped plate 30 to adjust its height. 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 facilitates the receiving of materials, and the rotating roller 38 facilitates the unloading and movement of materials.

[0044] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0045] The cylindrical material is passed 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. The second motor 19 is started, and the drive end of the second motor 19 drives the worm gear 20 to rotate. The worm gear 20 drives the worm wheel 18 to rotate, and the worm wheel 18 drives the threaded disc 17 to rotate. Since the moving block 15 is engaged with the threaded disc 17 through the threaded groove, the rotation of the threaded disc 17 drives the moving block 15. At this time, the moving block 15 moves along the path of the guide groove 14, thereby pushing the clamping plate 1. 6. The material is clamped and fixed at three points. The second cylinder 28 is activated, which pushes the clamping plate 29 to initially clamp and fix the material. The electric push rod 37 is activated, and the telescopic end of the electric push rod 37 pushes the drive plate 35. Under the action of the dovetail block 34, the drive plate 35 moves along the path of the dovetail groove 33. At this time, the drive plates 35 push towards each other and push the support rod 36 to perform support movement, so that the support rod 36 pushes the V-shaped plate 30 to adjust the height. The V-shaped plate 30 drives the lifting rod 31 to move out of the lifting cylinder 32, adjusting the V-shaped plate 30. The height of plate 30 facilitates material receiving. The cutting machine 7 is started and allowed to idle. The first cylinder 6 is activated, pushing the cutting machine 7 to feed, thus enabling it to cut the material. At this time, the first motor 9 is started, driving the drive gear 10 to rotate. The drive gear 10 meshes with the driven gear, causing the drive gear 10 to drive the driven gear ring 8. The driven gear ring 8 drives the rotating disk 3 to rotate, thus rotating the cutting machine 7 and enabling it to perform circumferential cutting on the material. In the cutting process, when continuous cutting is required, the clamping assembly is released, and the third motor 25 is started. The drive 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, the rotation of the lead screw 26 has a driving effect on the displacement block 27. The displacement block 27 moves along the opening path, which in turn causes the clamping plate 29 to move the material to feed. At this time, the second motor 19 is started again, so that the clamping plate 16 clamps the material again, and then the material is cut again by the ring cutting assembly to realize the continuous cutting process.
