Description

Technical Field

[0001] This application relates to the field of seamless steel tube blank processing, and in particular to a tooling for processing high-pressure seamless steel tube blanks. Background Technology

[0002] Seamless steel pipes generally need to undergo surface peeling before leaving the factory. After the treatment, the steel pipes can be cut into sections of different lengths according to customer requirements.

[0003] In related technologies, automated peeling equipment for high-pressure seamless steel pipes generally uses rotating blades for peeling. The debris generated during peeling can easily injure passing workers, and the safety needs to be improved. Summary of the Invention

[0004] To improve safety during processing, this application provides a tooling for processing high-pressure seamless steel pipe blanks.

[0005] A high-pressure seamless steel pipe billet processing fixture includes a base, a steel pipe peeling mechanism disposed on the base, and a transport mechanism disposed on the base. The transport mechanism is used to transport seamless steel pipes. The base is provided with a plurality of baffles, which are spliced ​​together with the base to form a processing cavity. The steel pipe peeling mechanism is located inside the processing cavity.

[0006] By adopting the above technical solution, the steel pipe peeling mechanism is installed in the processing chamber through a partition, and the splashing debris is blocked by the baffle, so that the cut debris is all in the processing chamber. This helps to reduce the possibility of debris flying out and scratching the workers, improves the safety during processing, and the splashing debris is all located in the processing chamber, which makes it easy to collect the debris.

[0007] Preferably, the peeling mechanism is provided with a heating mechanism on the base, and the transport mechanism transports the steel pipe through the heating mechanism and the steel pipe peeling mechanism in sequence.

[0008] By adopting the above technical solution, in the actual processing, the transport mechanism transports the steel pipe through the heating mechanism and the steel pipe peeling mechanism in sequence. The heating mechanism heats the steel pipe, which is beneficial to softening the oxide layer and rust on the surface of the steel pipe, reducing the friction between the blades on the steel pipe peeling mechanism and the steel pipe, improving the surface quality of the steel pipe, reducing the twisting deformation of the steel pipe, and improving the compressive strength of the steel pipe after peeling.

[0009] Preferably, the base has a waste chip groove that communicates with the processing cavity, and an extrusion block is slidably connected to the base. The extrusion block slides into or out of the waste chip groove, and a driving assembly is provided on the base to drive the extrusion block to move.

[0010] By adopting the above technical solution, in actual use, the debris generated during peeling falls into the waste debris trough. The drive component drives the extrusion block to move and extend into the waste debris trough, causing the waste debris in the waste debris trough to accumulate together, which helps to improve the collection efficiency of waste debris.

[0011] Preferably, the base has a discharge port, and a support plate is hinged to the base to cover the discharge port. The support plate is located below the waste chip trough. A positioning plate is slidably connected to the base. The positioning plate and the extrusion block are located on opposite sides of the positioning plate. The positioning plate has a support surface to support the support plate. An elastic element is provided on the base, and the elastic element abuts against the positioning plate, causing the positioning plate to tend to move closer to the extrusion block.

[0012] By adopting the above technical solution, as the amount of debris in the waste chip trough gradually increases, the amount of debris between the extrusion plate and the positioning plate increases. The extrusion plate squeezes the positioning plate through the debris, causing the positioning plate to move away from the support plate, so that the support surface is separated from the support plate. The support plate rotates downward to open the discharge port, which facilitates the automatic discharge of waste chips.

[0013] Preferably, the extrusion block is provided with a rack, a gear is rotatably connected to the base, a reel is coaxially fixed to the gear, the gear meshes with the rack, a connecting rope is wound on the reel, the connecting rope is used to connect the support plate, and when the extrusion block moves toward the direction of extending into the waste trough, the take-up reel is driven to wind up the connecting rope.

[0014] By adopting the above technical solution, the extrusion block moves towards the waste chip trough, the rack meshing gear drives the gear to rotate towards the waste chip trough, and the reel winds up the connecting rope to make the support plate cover the discharge port. After the lumps of debris are separated from the waste chip trough from the discharge port, the support plate can close the discharge port in time when the extrusion block pushes the debris closer to the discharge port, which facilitates the reset of the support plate.

[0015] Preferably, the positioning plate is provided with a guide surface, which is inclined from the direction close to the waste chute to the direction close to the support surface, and the guide surface is used to abut against the support plate.

[0016] By adopting the above technical solution and setting a guide surface, when the connecting rope rotates and the support plate re-covers the feed opening, the support plate abuts against the guide surface, causing the positioning plate to move away from the support plate along the inclined direction of the guide surface, so that the support surface can re-support the support plate.

[0017] Preferably, the waste trough includes a receiving trough and a discharging trough. The receiving trough is connected to the processing chamber, and the discharging trough is located on the side of the receiving trough away from the extrusion block. A cover plate is provided on the base, and the cover plate is used to cover the receiving trough.

[0018] By adopting the above technical solution, in the actual processing, the extrusion block slides into the receiving groove, pushes the debris in the receiving groove into the discharge groove, and the discharge groove is covered by the cover plate, so that the extrusion block can squeeze the debris in the discharge groove into blocks, which is convenient for collection.

[0019] Preferably, the baffle includes a circumferential wall disposed on the base and a top cover hinged to the circumferential wall, the top cover being used to cover the processing cavity.

[0020] By adopting the above technical solution, when the cutting tool in the steel pipe peeling mechanism malfunctions, the top cover can be opened to expose the processing chamber, making it easier to repair the steel pipe peeling mechanism.

[0021] In summary, this application includes at least one of the following technical effects: 1. By using baffles to block flying debris, it is beneficial to reduce the possibility of debris flying out and injuring workers, thereby improving the safety of processing. In addition, the flying debris is located inside the processing chamber, making it easy to collect the debris. 2. Heating the steel pipe by the heating mechanism is beneficial to softening the oxide layer and rust on the surface of the steel pipe, reducing the friction between the blades on the steel pipe peeling mechanism and the steel pipe, reducing the twisting deformation of the steel pipe, and improving the compressive strength of the steel pipe after peeling. 3. The cover plate closes the feeding trough, which makes it easier for the extrusion block to compress the debris in the feeding trough into blocks, making it easier to collect.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] This application discloses a tooling for processing high-pressure seamless steel tube blanks. (Refer to...) Figure 1 and Figure 2 A high-pressure seamless steel pipe billet processing fixture includes a base 1, a steel pipe peeling mechanism 2, and a transport mechanism 3. The steel pipe peeling mechanism 2 and the transport mechanism 3 are both located above the base 1. The steel pipe peeling mechanism 2 is fixedly connected to the base 1. The transport mechanism 3 is located on opposite sides of the steel pipe peeling mechanism 2 and is slidably connected to the base 1. The base 1 is provided with a drive assembly 4, which drives the transport mechanism 3 to move.

[0031] Reference Figure 1 and Figure 2 The transport mechanism 3 includes a frame 31 and several grippers 32. The grippers 32 are slidably connected to the frame 31. The grippers 32 slide close to or away from each other. The grippers 32 are used to clamp the steel pipe on both sides to position the steel pipe. The drive component 4 drives the transport mechanism 3 to move, thereby moving the steel pipe.

[0032] Reference Figure 2 and Figure 3 A heating mechanism 5 is fixed on the base 1. The heating mechanism 5 includes a mounting frame 51 and a heating element 52. The mounting frame 51 is located above the base 1 and is fixedly connected to the base 1. The mounting frame 51 is located on the side of the transport mechanism 3 near the steel pipe peeling mechanism 2. The mounting frame 51 and the base 1 are spliced ​​to form a channel. The heating element 52 is located in the channel, through which the steel pipe passes. The heating element 52 heats the steel pipe passing through the channel. The transport mechanism 3 drives the steel pipe to first pass through the mounting frame 51 and then through the steel pipe peeling mechanism 2. The temperature inside the channel is lower than the deformation temperature of the steel pipe.

[0033] Reference Figure 2A baffle 6 is fixed on the base 1. The baffle 6 includes a circumferential wall 61 and a top cover 62. A self-aligning frame 63 is fixed on the base 1. The self-aligning frame 63 is located on one side of the steel pipe peeling mechanism 2. The distribution direction of the self-aligning frame 63 and the steel pipe peeling mechanism 2 is parallel to the conveying direction of the conveying mechanism 3. The baffle 6 and the base 1 are spliced ​​to form a processing cavity 64. The steel pipe peeling mechanism 2 is located in the processing cavity 64. The top cover 62 is located above the baffle 6. The top cover 62 is hinged to one of the baffles 6. The hinge axis of the top cover 62 is set horizontally. The hinge axis of the top cover 62 is parallel to the conveying direction of the conveying mechanism 3. The top cover 62 rotates to close the processing cavity 64. A handle 65 is welded and fixed on the top cover 62. The handle 65 and the hinge axis of the top cover 62 are located on opposite sides of the top cover 62. The handle 65 is used to abut against the upper end of the other baffle 6 to limit the handle 65.

[0034] Reference Figure 3 and Figure 4 A waste chip trough 11 is provided on the base 1. The waste chip trough 11 includes a receiving trough 111 and a discharging trough 112, which are connected. The distribution direction of the receiving trough 111 and the discharging trough 112 is parallel to the conveying direction of the conveying mechanism 3. The receiving trough 111 is located directly below the processing chamber 64 and is connected to the processing chamber 64. The receiving trough 111 is used to receive waste chips in the processing chamber 64. An extrusion block 7 is slidably connected to the base 1. The sliding direction of the extrusion block 7 is consistent with the conveying direction of the conveying mechanism 3. The extrusion block 7 and the discharging trough 112 are located on opposite sides of the receiving trough 111, and the extrusion block 7 slides into or out of the receiving trough 111. When the extrusion block 7 extends into the receiving groove 111, its outer peripheral wall adheres to the inner wall of the receiving groove 111. The extrusion block 7 pushes the waste in the receiving groove 111 into the discharge groove 112. A cover plate 18 is fixedly connected to the base 1, and the cover plate 18 is located above the discharge groove 112. The vertical projection of the cover plate 18 is located on the discharge groove 112. The cover plate 18 covers the discharge groove 112, so that the waste in the discharge groove 112 is pressed against the inner wall of the discharge groove 112 and the cover plate 18 under the action of the extrusion block 7. This facilitates the extrusion block 7 to compress the waste in the discharge groove 112 into blocks, making it easier to collect the waste generated during processing. The drive assembly 4 drives the extrusion block 7 to move.

[0035] Reference Figure 3 and Figure 4The drive assembly 4 includes a first drive component 41, a second drive component 42, a first reciprocating screw 43, a second reciprocating screw 44, and a third reciprocating screw 45. The first drive component 41 and the second drive component 42 are fixed to the base 1, and are located on opposite sides of the steel pipe peeling mechanism 2. The first reciprocating screw 43 is located on the side of the first drive component 41 away from the steel pipe peeling mechanism 2. The output shafts of the first reciprocating screw 43 and the first drive component 41 are fixedly connected. The second reciprocating screw 44 is located on the side of the second drive component 42 away from the steel pipe peeling mechanism. On one side of component 2, the output shafts of reciprocating screw 44 and drive component 42 are fixedly connected. Reciprocating screw 43 and reciprocating screw 44 are threadedly connected to the frame 31 on both sides of the steel pipe peeling mechanism 2. Drive component 41 and drive component 42 drive the frame 31 to slide. Reciprocating screw 45 is located on the side of drive component 42 near the steel pipe peeling mechanism 2. Reciprocating screw 45 is coaxially fixed with the output shaft of drive component 42. Drive component 42 drives reciprocating screw 45 to rotate. Reciprocating screw 45 is threadedly connected to the extrusion block 7. In this embodiment, drive component 41 is a motor, and drive component 42 is a dual-axis motor.

[0036] Heating the steel pipe before peeling increases the temperature of impurities on the pipe surface, making it easier for the impurities to detach from the pipe. It also makes it easier for the debris entering the receiving trough 111 and the discharge trough 112 to deform, resulting in more compact debris compression.

[0037] Reference Figure 4 and Figure 5 A discharge port 12 is provided on the base 1, located below the base 1 and below the discharge trough 112, and the discharge port 12 is connected to the discharge trough 112. A support plate 13 is hinged to the base 1, and the hinge axis of the support plate 13 is parallel to the conveying direction of the conveying mechanism 3. The support plate 13 is used to rotate and cover the discharge port 12, and to support the debris in the discharge trough 112. A positioning plate 14 is slidably connected to the base 1, and the sliding direction of the positioning plate 14 is parallel to the conveying direction of the conveying mechanism 3. The positioning plate 14 is located on the side of the support plate 13 away from the extrusion block 7. The positioning plate 14 slides closer to or away from the support plate 13. A support surface 15 is machined on the positioning plate 14. The support surface 15 is flat and is used to abut against the lower end of the support plate 13 to support the support plate 13. An elastic element 16 is fixed on the base 1. The elastic element 16 is located on the side of the positioning plate 14 away from the support plate 13. The opposite ends of the elastic element 16 are fixedly connected to the base 1 and the positioning plate 14, respectively. The elastic element 16 presses against the positioning plate 14, causing the positioning plate 14 to tend to move and extend into the feed groove 112. This facilitates the positioning plate 14 pressing against the support plate 13, making it less likely for the support surface 15 to detach from the support plate 13, and improving the positioning stability of the support plate 13. In this embodiment, the elastic element 16 is a spring.

[0038] In the actual processing, as the debris in the feeding trough 112 is squeezed into blocks, the extrusion block 7 squeezes the debris to press against the positioning plate 14, pushing the positioning plate 14 to move away from the support plate 13, so that the support surface 15 is separated from the support plate 13, and the support plate 13 rotates to open the feeding port 12, so that the debris blocks are discharged.

[0039] Reference Figure 4 and Figure 6 A gear 71 is rotatably connected to the base 1, and a rack 72 is fixedly connected to the extrusion block 7. The rack 72 is located above the extrusion block 7, and the length direction of the rack 72 is parallel to the sliding direction of the extrusion block 7. The gear 71 is located above the extrusion block 7, and the rotation axis of the gear 71 is horizontally set and perpendicular to the sliding direction of the extrusion block 7. The gear 71 meshes with the rack 72. A reel 73 is coaxially fixed to the gear 71. The reel 73 is located outside the base 1, and a connecting rope 74 is wound on the reel 73. The end of the connecting rope 74 away from the reel 73 is fixedly connected to the end of the support plate 13 away from its own hinge axis.

[0040] A friction surface is machined on the base 1. The friction surface is located on the moving path of the positioning plate 14. The friction surface is used to abut against the positioning plate 14 to reduce the reset speed of the positioning plate 14.

[0041] As the extrusion block 7 moves closer to the positioning plate 14 to extrude debris, the rack 72 drives the gear 71 to rotate, which in turn drives the reel 73 to rotate, causing the reel 73 to wind up the connecting rope. The connecting rope tightens the support plate 13, causing the support plate 13 to cover the discharge port 12. If the support surface 15 is disengaged from the support plate 13 at this time, the support plate 13 covers the discharge port 12 through the connecting rope. As the extrusion block 7 moves away from the positioning plate 14, the connecting rope 74 is unwound through the cooperation between the gear 71, rack 72 and reel 73, causing the support plate 13 to rotate and open the feed port before the positioning plate 14 is reset, thus discharging the debris.

[0042] Reference Figure 5 and Figure 6 A guide surface 17 is machined on the lower end surface of the positioning plate 14. The guide surface 17 is located below the support surface 15. The guide surface 17 is inclined towards the support surface 15 in the direction close to the material feeding groove 112. The guide surface 17 is used to abut against the upper end of the support plate 13.

[0043] After the positioning plate 14 is reset, the pressing block 7 moves towards the positioning plate 14, causing the connecting rope 74 to tighten the support plate 13, which in turn drives the support plate 13 to rotate and approach the positioning plate 14. The support plate 13 presses against the guide surface 17 of the positioning plate 14, causing the positioning plate 14 to move away from the support plate 13 and leave the moving path of the support plate 13, until the support plate 13 rotates to above the support surface 15. When the positioning plate 14 is reset, the support surface 15 abuts against the support plate 13 to support the support plate 13, making it easier for the support plate 13 to open the discharge port 12 and then close the discharge port 12 again.

[0044] The implementation principle of the high-pressure seamless steel pipe billet processing fixture in this application embodiment is as follows: When the steel pipe peeling mechanism 2 processes the steel pipe, the generated debris falls into the receiving groove 111, which is not easy to splash out and scratch the workers. The driving component 4 drives the extrusion block 7 to move and push the debris in the receiving groove 111 into the discharge groove 112. As the amount of debris in the discharge groove 112 increases, the extrusion block 7 continues to push the debris in. The debris in the discharge groove 112 is squeezed into blocks, which makes it easier for workers to clean up the debris. Compared with cleaning scattered debris, the debris is less likely to cause injury during cleaning, which is conducive to further improving safety.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
