Description

Technical Field

[0001] The invention relates to the technical field of hollow hook production, in particular to a cutting device for hollow hook production. Background Art

[0002] The hollow hook is a specially designed lifting tool. Its internal hollow structure reduces its own weight while ensuring strength. In particular, the hook made of thin-walled tubes is widely used in many fields such as machinery manufacturing, aerospace, and medical equipment due to its lightweight and certain strength characteristics. Since the hollow hook is light in weight and easy to operate, it can improve the efficiency of handling and reduce the energy consumption of equipment. When producing the hollow hook, a cutting device is required to first cut the long tube into short tubes, and then the short tube is bent and formed into the shape of the hook.

[0003] When the existing cutting device cuts thin-walled tubes, the thin-walled tubes are easily deformed at the incision due to the pressure applied by the saw blade and the high temperature generated when the saw blade cuts, and the deformed thin-walled tubes need to be corrected later. Although a long rod is usually inserted into the thin-walled tube to prevent the thin-walled tube from deforming during cutting as much as possible, in order to facilitate cutting, only one end of the long rod is fixed to the cutting device, and its center of gravity is far away from the fixed point (similar to a fisherman holding the tail of a fishing rod). Therefore, when the thin-walled tube rotates, the long rod will shake away from its fixed point, causing the thin-walled tube on the outside of the long rod to shake as well. Since the wall of the thin-walled tube is relatively thin, the tube body will be severely deformed under high-speed shaking. Summary of the Invention

Manual unloading is unnecessary, which not only reduces labor costs but also avoids the dangers of manual unloading.

[0022] 4. The rotation of the turntable can move the severely worn saw blade to the outermost or uppermost side, making it convenient for the staff to remove the worn saw blade and replace it with a new one while staying away from the rotating saw blade, thus avoiding downtime to replace the saw blade, thereby improving the cutting efficiency of the pipe.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figure 1 - Figure 10 In an embodiment of the present invention, a cutting device for producing hollow hooks includes a processing table 1, a support tube 5, an internal support mechanism 6, a rotating mechanism 7, and a pressing mechanism 8. The internal support mechanism 6 is provided at one end of the support tube 5 for supporting the inside of the pipe to be cut. The rotating mechanism 7 is provided on the top surface of the processing table 1. The pressing mechanism 8 is provided above the rotating mechanism 7 and can fix the cut pipe on the rotating mechanism 7. The top surface of the processing table 1 is provided with a processing mechanism 2. A plurality of support mechanisms 3 for clamping and supporting the support tube 5 are provided at equal intervals at one end of the top surface of the processing table 1. The inner top surface of the processing table 1 is provided with a pushing mechanism 4 for unloading the cut pipe from the support tube 5.

[0036] The processing mechanism 2 includes two symmetrical lifting assemblies 21 fixedly connected to the top surface of the processing table 1. A turntable 22 is rotatably connected between the two lifting assemblies 21 via a connecting shaft. A servo motor 221 fixedly connected to the connecting shaft is fixedly connected to the top surface of one of the lifting assemblies 21. A plurality of cutting assemblies 23 for cutting pipes are arranged at equal angles on the side of the turntable 22. A driving assembly 24 for driving the plurality of cutting assemblies 23 is provided on the other side of the turntable 22.

[0037] The supporting mechanism 3 includes a profile frame 31 fixedly connected to the top surface of the processing table 1 and two symmetrical guide rails 34. The inner top surface of the profile frame 31 is slidably connected to two symmetrical splints 32. Both end surfaces of the profile frame 31 are penetrated by a rotating threaded sleeve 33. The interior of the threaded sleeve 33 is screwed and connected to a screw 331 fixedly connected to the splint 32 at the corresponding position. The outer wall of the threaded sleeve 33 is fixedly connected to a gear 5 332. The top surface of the guide rail 34 is slidably connected to a rack 35 meshing with the gear 5 332 at the corresponding position. The guide rail 34 has a V-shaped structure. The interior of the guide rail 34 is slidably connected to a cylindrical block 36 fixedly connected to the rack 35 at the corresponding position. An elastic rope is fixedly connected between the cylindrical block 36 and the guide rail 34 at the corresponding position.

[0038] Specifically, first, one end of the support tube 5 is fixed between the multiple support mechanisms 3, and the internal support mechanism 6 is located on both sides of the cutting assembly 23. Then, the pipe to be cut is put on the other end of the support tube 5, and the pipe is located on the rotating mechanism 7. The turntable 22 drives the multiple cutting assemblies 23 and the driving assembly 24 to move downward through the driving of the two lifting assemblies 21. At the same time, the lowest cutting assembly 23 is rotated by the driving of the driving assembly 24. During the downward movement of the turntable 22, the pressing mechanism 8 also moves downward to fix the pipe on the rotating mechanism 7. The pipe is rotated by the rotation of the rotating mechanism 7 until the lowest cutting assembly 23 contacts the pipe, and as the cutting assembly 23 continues to move downward, the pipe can be cut. Since the diameter of the support tube 5 is usually smaller than that to be cut, The inner diameter of the cut pipe is determined, so the short pipe after being cut is hung on the support pipe 5 under the action of its own gravity. At this time, the bottom end of the short pipe is lower than the bottom end of the long pipe. Then, the short pipe is moved to multiple profiles 31 by the driving of the pushing mechanism 4. When the short pipe pushes the two racks 35 at the first profile 31 to move, the movement of the rack 35 causes the gear five 332 and the threaded sleeve 33 at the corresponding position to rotate, thereby causing the two splints 32 at the first profile 31 to move away from each other until the distance between the two splints 32 reaches the maximum. At this time, the pushing mechanism 4 pushes the short pipe through the first profile 31. Since the guide rail 34 is a V-shaped structure, when the rack 35 disengages from the gear five 332 at the corresponding position and moves to the inclined surface of the guide rail 34, the two racks The end spacing of 35 begins to increase until the short tube completely passes through the first profile 31 and moves to the second profile 31. At this time, the two racks 35 at the first profile 31 move in the opposite direction and return to their original positions under the action of their respective elastic ropes. At this time, the two splints 32 at the first profile 31 also begin to approach each other and return to their original positions during the reverse movement of the two racks 35 until the two splints 32 clamp the support tube 5. When the short tube begins to pass through the second (or subsequent multiple) profiles 31, the two splints 32 at the profile 31 also open to allow the short tube to pass through. After passing through, the two splints 32 clamp the support tube 5 again for support until the short tube passes through the last profile 31 and is separated from the support tube 5. Under the action of its own gravity, the two racks 35 at the pushing mechanism 4 and the last molding frame 31 are separated and fall. When the pushing mechanism 4 pushes the short pipe, the bottom cutting assembly 23 continues to cut the long pipe (the other end of the long pipe can be pushed manually or a special pushing device can be used to push the long pipe forward). The device prevents the cutting assembly 23 from deforming the pipe cut by inserting the long pipe into one end of the support tube 5 and supporting the inner wall of the part to be cut through the inner support mechanism 6. During cutting, the support tube 5 is supported by multiple support mechanisms 3 in turn, which can increase the stability of the support tube 5, thereby increasing the stability of the long pipe and avoiding the situation where the long pipe is rotated by the rotating mechanism 7 and causes serious shaking when the long pipe is cut.Therefore, deformation and bending of the long pipe body can be avoided as much as possible.

[0039] Example 1

[0040] like Figure 7 and Figure 8 As shown, in this embodiment, sliding holes are provided on both opposite side surfaces of the guide rail 34, and the outer wall of the cylindrical block 36 is fixedly connected with two symmetrical sleeves 361 that slide through the sliding holes at corresponding positions. The internal sliding sleeve of the sleeve 361 is connected with a plug post 37, and a spring 371 is fixedly connected between the plug post 37 and the sleeve 361 at the corresponding position. The plug post 37 has a T-shaped structure, and a push rack 38 is provided between the ends of the two racks 35 at relative positions. A spherical groove is provided at one end of the rack 35, and both ends of the push rack 38 are fixedly connected with steel balls that are movably engaged with the spherical grooves at corresponding positions.

[0041] In this embodiment, when the pushing mechanism 4 pushes the cut short pipe to move toward the multiple support mechanisms 3, the end of the short pipe first contacts the first pushing frame 38. Under the thrust of the pushing mechanism 4, the short pipe drives the first pushing frame 38 to move, thereby driving the two racks 35 here to move. The movement of the rack 35 causes the gear five 332 at the corresponding position and the threaded sleeve 33 at the corresponding position to rotate. The rotating threaded sleeve 33 can make the screw 331 and the clamping plate 32 at the corresponding position move until the distance between the two clamping plates 32 at the first molding frame 31 reaches the maximum. At this time, the short pipe drives the first pushing frame 38 to pass through the first molding frame 31, and the rack 35 here disengages from the gear five 332 at the corresponding position, and the two racks 35 move to the inclined surface of the guide rail 34 under the thrust. When the rack 35 no longer moves under the thrust, Figure 7 As shown, the stop block fixed in the middle of the push rack 38 is a triangular structure. At this time, the short tube is under the action of the thrust, and the end of the short tube is tilted up under the action of the triangular stop block, while the other end of the short tube is still in contact with the pushing mechanism 4 until the short tube is separated from the push rack 38 under the action of the pushing mechanism 4 (in order to avoid the stop block on the push rack 38 from scratching the outer wall of the short tube, the top of the stop block can be made of rubber). At this time, the two racks 35 at the first shaped frame 31 are no longer subjected to the thrust applied by the pushing mechanism 4, so the racks 35 move in the opposite direction and return to their original position under the elastic force of the elastic rope at the corresponding position.

[0042] Example 2

[0043] like Figure 9As shown, in this embodiment, a rectangular hole is opened through one end of the top surface of the processing table 1, and two symmetrical fixed blocks are fixedly connected to one end of the inner top surface of the processing table 1 and at both ends of the rectangular hole. The pushing mechanism 4 includes two sprockets 41 that are rotatably connected between the two fixed blocks at corresponding positions through rotating shafts. A chain 42 is sleeved between the two sprockets 41, and a plurality of pushing blocks 43 are fixedly connected to the chain 42 at equal intervals, one end of which passes through the fixed block at the corresponding position. A driving motor 2 44 is fixedly connected to the inner top surface of the processing table 1, and the output end of the driving motor 2 44 is fixedly connected to the rotating shaft at the corresponding position.

[0044] In this embodiment, the chain 42 can be rotated under the action of the two sprockets 41 by driving the second drive motor 44, so that the multiple push blocks 43 fixed on the chain 42 can move back and forth. The reciprocating push blocks 43 can push the short pipes that have been cut and hung on the support tube 5 to the multiple support mechanisms 3 for unloading, without the need for manual unloading, which not only reduces labor costs but also avoids the dangers of manual unloading.

[0045] Example 3

[0046] like Figure 3-Figure 6As shown, in this embodiment, a rectangular shell 223 is fixedly connected to one side of the turntable 22 and located on the outside of the connecting shaft. The cutting assembly 23 includes a movable plate 231 slidably connected to the turntable 22, and an electric push rod 232 is fixedly connected between the movable plate 231 and the rectangular shell 223. The bottom surface of the movable plate 231 is provided with two symmetrical mounting plates 233, one of which is fixedly connected to the movable plate 231 at the corresponding position, and the other mounting plate 233 is slidably connected to the movable plate 231 at the corresponding position. A mounting seat is rotatably passed through the bottom end of the side of the mounting plate 233, and a saw blade 234 is detachably connected between the two mounting seats at relative positions. The side of the mounting plate 233 fixedly connected to the movable plate 231 is fixedly connected to a sliding rod, and a spring 2 is fixedly connected between the two mounting plates 233 at relative positions and located on the outside of the sliding rod. A plurality of rectangular frames 222 are fixedly connected at equal angles on the side of the turntable 22. A limit rod is fixedly connected between the two inner ends of the frame 222, and one end of the movable plate 231 is fixedly connected to a slider that slides through the limit rod. A plurality of conductive slip rings 225 are arranged at equal intervals on the outer wall of the connecting shaft, and a bearing is arranged on the outer wall of the conductive slip ring 225. A plurality of through holes 224 are opened at equal angles in a ring shape on the side of the turntable 22, and a rotating rod that slides through the through holes 224 at corresponding positions is fixedly connected to one end of the mounting seat close to the turntable 22, and a gear 1 235 is fixedly connected to the outer wall of the rotating rod. The driving assembly 24 includes a sleeve 241 that is tightly fitted with multiple bearings, one end of the outer wall of the sleeve 241 is fixedly connected to a gear 2 242 that meshes with multiple gears 1 235, and the other end of the outer wall of the sleeve 241 is fixedly connected to a gear 3 243. The top surface of the other lifting assembly 21 is fixedly connected to a driving motor 1 244, and the output end of the driving motor 1 244 is fixedly connected to a gear 4 245 that meshes with the gear 3 243.

[0047] In this embodiment, the saw blade 234 is first fixed between two mounting plates 233 at relative positions (the installation and removal method of the saw blade 234 is the same as the installation and removal method of the pipe cutting machine saw blade 234 in the prior art). The driving motor 1 244 drives the sleeve 241 to drive the gear 2 242 to rotate, thereby making the multiple saw blades 234 rotate at high speed. The electric push rod 232 controls the movable plate 231 to drive the saw blade 234 to move, thereby controlling the engagement and separation of the gear 1 235 and the gear 2 242. When cutting the pipe, the multiple electric push rods 232 control the gear 1 235 at the bottom to engage with the gear 2 242, thereby making the bottom saw blade 234 rotate at high speed. Then, the two lifting assemblies 21 move the turntable 22 downward until the bottom saw blade 234 cuts the pipe. After the bottom saw blade 234 has been cutting for a period of time, the turntable 22 is rotated by the drive of the servo motor 221, and the original bottom saw blade 234 is moved upward, while one of the adjacent saw blades 234 is moved to the bottom to cut the pipe. When one of the saw blades 234 needs to be replaced, the saw blade 234 can be moved to the outermost or uppermost side first, and then the saw blade 234 can be removed from between the two mounting plates 233 at the corresponding position, and a new saw blade 234 can be installed. During the process of disassembling and installing the saw blades 234, the bottom saw blade 234 can continue to cut the pipe, avoiding the need to stop the machine to replace the saw blade 234 when cutting the pipe, thereby improving the cutting efficiency of the pipe, and through the rotation of the turntable 22, multiple saw blades 234 can take turns cutting the pipe, thereby improving the accuracy of the cut pipe.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
