Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe production, in particular to a continuous production system for stainless steel seamless pipes. Background Art

[0002] Stainless steel pipes are divided into two categories according to the production method: seamless pipes and welded pipes. Stainless steel welded pipes are made by curling and welding stainless steel plates, including straight seam welded pipes and spiral welded pipes. Stainless steel welded pipes are made directly from stainless steel plates, so they have uniform wall thickness, precise dimensions, and are easy to make thin-walled pipes. Their manufacturing process is relatively simple and low-cost, but due to the presence of welds, their ability to withstand pressure and high temperatures is relatively weak, so their application range is relatively limited. Stainless steel seamless pipes are first produced by perforation to produce rough pipes, and then rough pipes are cold rolled or cold drawn to size. Their materials are uniform, so their ability to withstand pressure and high temperatures is relatively strong, and their application range is wide. However, because their forming mainly depends on the plastic extension of the material itself, their wall thickness is uneven, their dimensional accuracy is poor, their surface finish is poor, and they cannot directly produce small-diameter thick-walled stainless steel seamless pipes.

[0003] To this end, the inventor used the forging machine disclosed in the utility model patent with the announcement number "CN205887931U" to forge stainless steel seamless pipes. This forging process uses a pulse forging method to achieve various purposes such as equal wall diameter reduction and wall diameter reduction. The processed steel pipe has uniform wall thickness, high precision, good inner and outer surface finish, and is convenient for the production of small-diameter thick-walled stainless steel seamless pipes. However, the forging machine must heat the original pipe material to achieve high-quality and efficient production, so the overall energy consumption is relatively high. For this reason, the inventor combined the existing perforation process of stainless steel seamless pipes to further improve and apply the forging process, and the invention was born.

[0006] As a preferred technical solution, the pipe outlet device includes a pipe outlet bracket arranged between the supporting wheel device and the diversion guide frame, and a pipe outlet guide frame with a pitch and swing setting is installed on the upper end of the pipe outlet bracket. A pipe outlet bracket for lifting the waste pipe is provided on the end of the pipe outlet guide frame close to the supporting wheel device, and the pipe outlet guide frame is connected to a pipe outlet controller, and the pipe outlet controller is used to make the other end of the pipe outlet guide frame form a continuous guide with the lower diversion guide frame.

[0007] As a preferred technical solution, the diverter controller includes a diverter control cylinder hingedly connected to the higher diverter guide frame.

[0008] As a preferred technical solution, the forged input device includes a forged input frame, on which are mounted a plurality of forged input wheels arranged along the input direction, a chain belt transmission is arranged between adjacent forged input wheels, and one of the forged input wheels is connected to a forged input driver.

[0009] The transmission gears are connected with the gears of the driven pulleys at the bottom of the gear train, and the two gears are connected with the gear train at the bottom of the gear train, and the two gears are connected with the gear train at the bottom of the gear train, and the gears are connected with the gear train at the bottom of the gear train.

[0010] As a preferred technical solution, a rolling device and a traction device are respectively provided upstream and downstream of the forging machine.

[0011] Due to the adoption of the above technical solution, a continuous production system for seamless stainless steel pipes includes a puncher and two forging machines. A core rod carriage is provided in the pipe outlet direction of the puncher, and a core rod assembly extending toward the puncher is installed on the core rod carriage. A plurality of arranged centering devices are provided between the puncher and the core rod carriage. Forging input devices corresponding to each of the forging machines are provided on the side of the centering device, and each of the forging input devices is provided with a diversion guide frame for guiding the rough pipe at the centering device to the corresponding forging input device.

Based on the fact that the forging speed of the forging machine is about half of the punching speed of the punching machine, this embodiment uses one punching machine in conjunction with two forging machines for use. The rough pipes punched out use the diversion controller to control the rough pipes to enter the higher diversion guide frame or the lower diversion guide frame, so as to output the rough pipes alternately to each of the forging input devices, thereby achieving the purpose of matching the processing speed. There is basically no waiting time required at each forging machine. When the rough pipes arrive at the forging input device, they can be forged immediately. The process is well connected, which is beneficial to reducing the loss of residual heat, further ensuring high-quality and efficient production and reducing production energy consumption.

DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0021] like Figure 1As shown, the continuous production system of stainless steel seamless steel pipes includes a punching machine 1 and two forging machines 8. A core rod carriage 2 is provided in the pipe outlet direction of the punching machine 1, and a core rod assembly 21 extending toward the punching machine 1 is installed on the core rod carriage 2. The core rod carriage 2 drives the core rod assembly 21 to extend to the punching machine 1. When the tube blank output from the punching machine 1 passes through the core head on the core rod assembly 21, the inner hole is expanded, and the tube blank is punched to become a rough pipe 9. The forging machine 8 forms a strong forging effect on the rough pipe 9 when it approaches the rough pipe 9 together through high-frequency reciprocating motion of multiple forging hammers in the radial direction of the rough pipe 9, and forms high-quality and efficient processing through high-frequency forging. The structural principles of the above punching and forging processes are well-known technologies that can be known to those skilled in the art, and will not be repeated here. Based on the fact that the forging processing speed of the forging machine 8 is about half of the punching processing speed of the punching machine 1, this embodiment uses one punching machine 1 to match two forging machines 8 for use.

[0022] like Figure 1 As shown, a plurality of arranged centering devices 3 are provided between the punching machine 1 and the core rod sports car 2, and the centering devices 3 are used to center the core rod assembly 21 during punching to ensure the stability of the center of the core rod assembly 21, and gradually release the centering effect during the processing of the rough pipe 9.

[0023] like Figure 2 and Figure 3 As shown, the centering device 3 includes a centering machine base 31, and two lower roller frames 32 are swingably installed at the lower part of the centering machine base 31, and centering lower rollers 33 are rotatably installed on the ends of the two lower roller frames 32 close to the core rod assembly 21; an upper roller frame 34 is swingably installed on the centering machine base 31 at the side of the core rod assembly 21 away from the forging input device 7, and a centering upper roller 35 is rotatably installed on the end of the upper roller frame 34 close to the core rod assembly 21; an opening and closing drive is connected to the end of the upper roller frame 34 away from the core rod assembly 21 Device 36, an opening and closing intermediate gear 38 is installed on the centering machine base 31 between the upper roller frame 34 and the lower roller frame 32 on the side away from the forging input device 7, an upper roller transmission gear 37 is installed on the rotating shaft of the lower roller frame 32, and lower roller transmission gears 39 are respectively installed on the rotating shafts of the two lower roller frames 32, the upper roller transmission gear 37 is constantly meshed with the opening and closing intermediate gear 38, the two lower roller transmission gears 39 are constantly meshed with each other, and the lower roller transmission gear 39 on the side away from the forging input device 7 is constantly meshed with the opening and closing intermediate gear 38.

[0024] When the opening and closing driver 36 drives the centering upper roller 35 to move toward the core rod assembly 21, through the transmission action of the upper roller transmission gear 37, the opening and closing intermediate gear 38 and the lower roller transmission gear 39, the centering upper roller 35 and the two centering lower rollers 33 finally form a state of clamping the core rod assembly 21 together to achieve the centering function. On the contrary, when the opening and closing driver 36 drives the centering upper roller 35 to move away from the core rod assembly 21, through the above-mentioned gear transmission action, the centering upper roller 35 and the two centering lower rollers 33 both form a movement away from the core rod assembly 21 to achieve the function of releasing the centering effect. The opening and closing driver 36 in this embodiment is realized by a drive cylinder hingedly connected to the upper roller frame 34.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, a supporting wheel device 4 for temporarily supporting the rough pipe 9 is provided between adjacent centering devices 3. When the rough pipe 9 reaches the centering device 3, the centering device 3 releases the centering function to avoid contact with the rough pipe 9 at high temperature. At this time, the supporting wheel device 4 temporarily supports the rough pipe 9 to prevent the rough pipe 9 from bending. The supporting wheel device 4 includes a supporting wheel machine base 41, on which a supporting wheel lifting seat 42 is vertically movable, on which a supporting wheel 43 is rotatably installed, and between the supporting wheel lifting seat 42 and the supporting wheel machine base 41, a supporting wheel lifting driver 44 is provided. Conventionally, a V-shaped bracket is provided on the wheel surface of the supporting wheel 43 to stably support the rough pipe 9.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, a forging input device 7 corresponding to each of the forging machines 8 is provided on the side of the centering device 3, and the forging input device 7 is used to feed the rough pipe 9 into the forging machine 8. The forging input device 7 in this embodiment includes a forging input frame 71, on which a plurality of forging input wheels 72 arranged along the input direction are installed, and a chain belt transmission is arranged between adjacent forging input wheels 72, and one of the forging input wheels 72 is connected to a forging input driver 73. The forging input driver 73 drives the forging input wheel 72 to rotate, and the rotating forging input wheel 72 inputs the rough pipe 9 thereon into the forging machine 8. Preferably, a V-shaped groove is also provided on the wheel surface of the forging input wheel 72 so that the rough pipe 9 can be stably input.

[0027] Preferably, if Figure 1As shown, a rolling device 81 and a traction device 82 are respectively provided upstream and downstream of the forging machine 8 to forcefully convey the input and output of the stainless steel pipe during the forging process to ensure reliable forging. The rolling device 81 and the traction device 82 both use at least two conveying rollers that are evenly arranged in the circumference and have an advance angle to rotate and convey the stainless steel pipe. This structural principle is a well-known technology that can be known to those skilled in the art and will not be repeated here.

[0028] Of course, if Figure 1 As shown, a forging output device 83 is also provided downstream of the forging machine 8 to output the forged stainless steel pipe. The forging output device 83 can be set with reference to the structural principle of the forging input device 7, which will not be described in detail here.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, each of the forging input devices 7 is provided with a diverter guide frame 5 for guiding the rough pipe 9 at the centering device 3 to the corresponding forging input device 7. Of course, the guide surface of the diverter guide frame 5 is a slope that gradually decreases in the direction close to the forging input device 7. This oblique guidance enables the rough pipe 9 to be guided to the forging input device 7 without power, which is beneficial to reducing production energy consumption. Of course, the diverter guide frame 5 close to the centering device 3 should have a lower end close to the centering device 3, so that there is an obvious height difference between the two diverter guide frames 5.

[0030] The lower diversion guide frame 5 is relatively fixedly arranged with respect to the corresponding forging input device 7, one end of the higher diversion guide frame 5 is hingedly connected to the corresponding forging input device 7, and the higher diversion guide frame 5 is connected with a diversion controller 51, and the diversion controller 51 is used to drive the free end of the higher diversion guide frame 5 to reach the lower diversion guide frame 5. Figure 1 ,as well as Figures 4 to 6 As shown, a pipe outlet device 6 for outputting the rough pipe 9 to the lower diversion guide frame 5 is provided between the supporting wheel device 4 and the centering device 3 .

[0031] like Figure 5 As shown, when the flow diversion controller 51 drives the higher flow diversion guide frame 5 to rise, a high-low layer is formed between the two flow diversion guide frames 5, and the waste pipe 9 output by the pipe outlet device 6 to the lower flow diversion guide frame 5 can be guided and transported along the lower flow diversion guide frame 5; Figure 6As shown, when the diversion controller 51 drives the higher diversion guide frame 5 to fall, the free end of the higher diversion guide frame 5 is at the lower diversion guide frame 5. At this time, the rough pipe 9 output by the pipe outlet device 6 will be guided and transported from the higher diversion guide frame 5, thereby realizing the alternating output of the rough pipe 9.

[0032] Preferably, if Figure 6 As shown, the forging input device 7 near the centering device 3 is provided with a descent limiting structure 52 for limiting the descent of the higher diverter guide frame 5, so as to limit the approach of the higher diverter guide frame 5 to the lower diverter guide frame 5. The diverter controller 51 includes a diverter control cylinder hingedly connected to the higher diverter guide frame 5.

[0033] like Figure 4 , Figure 5 and Figure 6 As shown, the pipe outlet device 6 includes a pipe outlet bracket 61 arranged between the supporting wheel device 4 and the diversion guide frame 5, and a pipe outlet guide frame 62 with a pitching swing arrangement is installed on the upper end of the pipe outlet bracket 61. The pipe outlet guide frame 62 is provided with a pipe outlet bracket 63 for supporting the waste pipe 9 on one end close to the supporting wheel device 4. The pipe outlet guide frame 62 is connected to a pipe outlet controller 64, and the pipe outlet controller 64 is used to make the other end of the pipe outlet guide frame 62 form a continuous guide with the lower diversion guide frame 5. When the pipe outlet controller 64 drives the pipe outlet guide frame 62 to swing, the pipe outlet bracket 63 supports the waste pipe 9, and when the pipe outlet guide frame 62 continues to swing to an inclined plane that matches the diversion guide frame 5, the waste pipe 9 rolls along the pipe outlet guide frame 62 toward the diversion guide frame 5, so as to realize the output of the waste pipe 9 from the position of the centering device 3. The pipe outlet controller 64 is also implemented by a control cylinder.

[0034] Based on the fact that the centering device 3 is in a single-side open state after releasing the centering effect, the two sets of forging machines 8 and forging input devices 7 in this embodiment are both located on the open side of the centering device 3; under this layout, this embodiment, by providing the pipe outlet device 6 for lifting the rough pipe 9 upwards to enable it to be output, can achieve the output of the rough pipe 9 while avoiding structural obstacles such as the centering lower roller 33 on the centering device 3, and divert the rough pipe 9 through the control of the diversion controller 51, which has a simple structure and low energy consumption.

[0035] In actual production, the punching speed of the punching machine 1 is mainly 4-5 m / min, and the forging speed of the forging machine 8 is mainly 2-3 m / min. One punching machine 1 is equipped with two forging machines 8, which can basically achieve the purpose of no-waiting processing of the rough pipe 9 at the forging processing site. The specific working process is as follows.

[0036] Initially, if Figure 2As shown, the diversion controller 51 drives the higher diversion guide frame 5 to be in a high position. The core rod sports car 2 drives the core rod assembly 21 to extend to the punching machine 1 to cooperate with the punching process. The first rough pipe 9 punched out gradually reaches the centering device 3. Figure 3 As shown, the centering device 3 releases the centering sequentially, such as Figure 4 As shown, the rough pipe 9 is finally supported by the supporting wheel device 4. The core rod vehicle 2 drives the core rod assembly 21 to leave the punching machine 1 and extract the rough pipe 9. Figure 5 As shown, the pipe outlet controller 64 drives the pipe outlet guide frame 62 to start swinging, and the pipe outlet bracket 63 lifts the rough pipe 9, and the rough pipe 9 leaves the supporting wheel device 4; in the process of the pipe outlet guide frame 62 continuing to swing, it gradually forms the same inclined state as the pipe outlet guide frame 62, and the rough pipe 9 falls along the pipe outlet guide frame 62 to the lower diversion guide frame 5, and finally enters the forging input device 7 close to the centering device 3, and the forging input device 7 inputs this first rough pipe 9 into the corresponding forging machine 8 to start forging.

[0037] The pipe outlet controller 64 drives the pipe outlet guide frame 62 to return to its original position, and the diversion controller 51 controls the corresponding diversion guide frame 5 to reach a low position. The core rod sports car 2 re-drives the core rod assembly 21 to extend to the punching machine 1, and the centering device 3 is re-centered. The second rough pipe 9 punched out gradually reaches the centering device 3, and the centering device 3 releases the centering in sequence, and the second rough pipe 9 is finally supported by the supporting wheel device 4. The core rod sports car 2 drives the core rod assembly 21 to leave the punching machine 1, and pulls out the second rough pipe 9. The core rod sports car 2 drives the core rod assembly 21 to leave the punching machine 1, and pulls out the rough pipe 9. Figure 6 As shown, the pipe outlet controller 64 drives the pipe outlet guide frame 62 to start swinging, and the pipe outlet bracket 63 lifts the second rough pipe 9, and finally enters the forging input device 7 away from the centering device 3 along the higher diversion guide frame 5. The forging input device 7 inputs the second rough pipe 9 into the corresponding forging machine 8 to start forging.

[0038] The pipe outlet controller 64 drives the pipe outlet guide frame 62 to return to its original position, and the diversion controller 51 controls the corresponding diversion guide frame 5 to return to the high position again, repeating the diversion action of the rough pipe 9, and the rough pipe 9 at the third perforation processing location is guided to the forging input device 7 near the centering device 3. The first rough pipe 9 on the forging input device 7 has been forged, and the third rough pipe 9 can be immediately input into the forging machine 8 for forging after it arrives. In this way, the time between perforation and forging is short, the waiting time for forging is short, the waste of residual heat is small, and the processing connection is good.

[0039] In this embodiment, the stainless steel tube blank is heated to 1100-1200°C before entering the punching machine 1. The rough tube 9 obtained after the tube blank is punched arrives at the supporting wheel device 4, and the residual temperature is still above 900°C. The tube outlet device 6 guides the rough tube 9 and passes through the diversion guide frame 5 to the forging input device 7, and is directly transported to the corresponding forging machine 8 for forging by the forging input device 7. Therefore, the forging machine 8 utilizes the residual heat of the punching process, eliminates the need for preheating, is conducive to reducing production energy consumption, and ensures high-quality and efficient production. Based on the fact that the forging speed of the forging machine 8 is about half of the punching speed of the punching machine 1, in this embodiment, one punching machine 1 is used in conjunction with two forging machines 8. The rough pipe 9 punched out is controlled by the diversion controller 51 to enter the higher diversion guide frame 5 or the lower diversion guide frame 5, so as to alternately output the rough pipe 9 to each of the forging input devices 7, thereby achieving the purpose of matching the processing speeds. In addition, there is basically no waiting time required at each forging machine 8. When the rough pipe 9 arrives at the forging input device 7, it can be forged immediately. The process is well connected, which is conducive to reducing the loss of residual heat, further ensuring high-quality and efficient production and reducing production energy consumption.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
