DETAILED DESCRIPTION

[0019] The present application is further described in detail below in conjunction with the accompanying drawings.

[0020] The embodiment of the present application discloses a stainless steel seamless pipe processing device.

[0021] Reference Figure 1 The stainless steel seamless pipe processing equipment includes a cutting frame 1 and a polishing mechanism 2. The cutting frame 1 is provided with a cutting assembly 3 for cutting a steel pipe, a feeding assembly 4 for periodically conveying the steel pipe to be cut to the cutting assembly 3, and a material transfer assembly 5 for conveying the cut steel pipe to the polishing mechanism 2. The polishing mechanism 2 is located at one side of the discharge port of the material transfer assembly 5, and the polishing mechanism 2 is used to polish the surface of the cut steel pipe.

[0022] like Figure 2 , Figure 3 As shown, the cutting assembly 3 includes a driving roller 30 rotatably arranged on the cutting frame 1, the driving roller 30 is arranged horizontally, and the rotating shaft of the driving roller 30 is linked to the output shaft of the motor installed on the cutting frame 1 through a belt. Two cutting discs 31 are coaxially penetrated on the driving roller 30, and the cutting discs 31 are respectively located at the left and right ends of the driving roller 30. Two groups of adjustment rings 32 are also arranged on the driving roller 30, and each group of adjustment rings 32 is respectively located at the left and right ends of the driving roller 30.

[0023] like Figure 2 , Figure 3As shown, there are multiple adjustment rings 32 in each group, and each adjustment ring 32 is coaxially arranged on the driving roller 30 in sequence. Each adjustment ring 32 in the same group is used to clamp and fix the corresponding cutting disc 31 on the driving roller 30, and the end of the driving roller 30 is also threadedly connected with a nut fastener 300 for locking the adjustment ring 32 on the driving roller 30. After the nut fastener 300 is unscrewed from the end of the driving roller 30, the installation position of the cutting disc 31 can be adjusted by adjusting the number of adjustment rings 32 on both sides of the cutting disc 31, thereby meeting the cutting requirements of steel pipes of different lengths.

[0024] like Figure 2 , Figure 3 As shown, the feeding assembly 4 includes two feeding belts 40 symmetrically arranged between the cutting discs 31 on both sides, and two groups of feeding gears 41 rotatably arranged on the cutting frame 1. The feeding belts 40 are respectively wound around the outside of each group of feeding gears 41, and the inner side walls of the feeding belts 40 are meshed with the outer circumferential surfaces of each group of feeding gears 41. The two groups of feeding gears 41 drive the feeding belts 40 on both sides to rotate synchronously under the drive of the same motor. The upper layer of the feeding belt 40 is arranged horizontally, and the length of the upper layer of the feeding belt 40 extends along the feeding direction of the steel pipe.

[0025] like Figure 2 , Figure 3 As shown, the steel pipe is used to be mounted on the upper layer of the feeding belts 40 on both sides. The feeding belts 40 are driven by the feeding gears 41 to drive the steel pipe to move toward the cutting disk 31. A plurality of push plates 42 arranged in sequence are fixedly mounted on the outer wall of the feeding belt 40. The push plates 42 are used to push the steel pipe toward the cutting disk 31.

[0026] like Figure 2 , Figure 3 As shown, the feeding assembly 4 also includes a pressing plate 43 located between the cutting discs 31 on both sides. The pressing plate 43 is located above the feeding belt 40, and the pressing plate 43 is arranged to be inclined downward along the feeding direction of the steel pipe. The top of the pressing plate 43 is arranged on the cutting frame 1, and the bottom of the pressing plate 43 is used to limit the steel pipe on the feeding belt 40. When the push plate 42 pushes the steel pipe to gradually move to the bottom of the pressing plate 43, the steel pipe can be effectively prevented from tilting and falling from the feeding belt 40 during cutting under the limitation of the pressing plate 43, thereby ensuring the stability of the steel pipe during cutting. After the cutting discs 31 on both sides complete cutting of the steel pipe, the steel pipe will be moved out from the bottom of the pressing plate 43 under the push of the pushing plate 42.

[0027] like Figure 3 , Figure 4As shown, two groups of waste conveyor belts 6 are rotatably arranged on the cutting frame 1, and the waste conveyor belts 6 are respectively located below the respective opposite cutting discs 31, and the waste conveyor belts 6 are driven by a motor. The upper surface of the waste conveyor belt 6 is arranged to be inclined downward along the feeding direction of the steel pipe. The waste conveyor belt 6 is used to receive the waste and waste chips of the steel pipe cut by the upper cutting disc 31. A waste collection bin 60 is also arranged on one side of the discharge port of the waste conveyor belt 6, and the waste collection bin 60 is used to collect the waste and waste chips of the steel pipe.

[0028] like Figure 4 , Figure 5 As shown, a waste filter 600 is fixedly installed at the feed port of the waste collection bin 60, and a cleaning brush 601 for cleaning the surface of the waste filter 600 is slidably arranged on the waste filter 600. The internal space of the waste collection bin 60 is separated by a partition into a storage chamber 610 for collecting steel pipe waste. A connecting rod 602 is fixedly arranged at one end of the cleaning brush 601 away from the storage chamber 610, and the connecting rod 602 extends from the outer wall of the waste collection bin 60 to the outside of the waste collection bin 60. The cleaning brush 601 is driven to move on the surface of the waste filter 600 by pushing the connecting rod 602. At this time, under the action of the cleaning brush 601, the waste remaining on the surface of the waste filter 600 can be swept into the cavity below the waste filter 600, and the steel pipe waste will be moved into the waste collection bin 60 under the push of the cleaning brush 601, so that the purpose of screening the steel pipe waste and the waste can be achieved.

[0029] like Figure 4 , Figure 5 As shown, the material transfer assembly 5 includes a material transfer rack 50 disposed on one side of the material discharge port of the feeding belt 40, and the material transfer rack 50 is arranged obliquely downward along the steel pipe discharge direction. A transition rack 51 is fixedly arranged horizontally at the bottom of the material transfer rack 50, and the material transfer assembly 5 also includes a material transfer machine 52 located below the transition rack 51, and a plurality of material transfer discs 520 arranged in sequence and evenly spaced are coaxially rotated on the material transfer machine 52, and three groups of material shifting fins 521 are evenly spaced circumferentially arranged on the outer circumferential surface of the material transfer disc 520. Each material transfer disc 520 keeps synchronous rotation under the drive of the same motor.

[0030] like Figure 4 , Figure 5As shown, the material transfer plate 520 is respectively located between two adjacent transition racks 51, and the material transfer fin 521 is used to periodically rotate from bottom to top between two adjacent transition racks 51. When the material transfer fin 521 rotates between the transition racks 51, the material transfer fin 521 will push the steel pipe located on the transition rack 51 to move out from the material outlet of the transition rack 51 to the polishing mechanism 2. Then the material transfer fin 521 will stop between the two transition racks 51. When the steel pipe rolls from the material transfer rack 50 to the transition rack 51, the steel pipe can be blocked on the transition rack 51 again by the material transfer fin 521. When the polishing mechanism 2 completes the polishing of the steel pipe, the material transfer fin 521 will rotate again, and the rear material transfer fin 521 will push the steel pipe to be automatically added to the polishing mechanism 2. This cycle is repeated, which improves the processing efficiency of the steel pipe, reduces the number of times the steel pipe is transported, reduces the collision of the steel pipe during the processing, further improves the yield rate of the steel pipe, and reduces the safety hazards in the transportation process.

[0031] like Figure 5 , Figure 6 as well as Figure 7 As shown, the material transfer assembly 5 also includes a plurality of guide rods 53 fixedly mounted at the bottom of the material transfer frame 50, and a limit frame 54 is movably arranged on the guide rods 53, and the limit frame 54 is lifted and slid along the length direction of the guide rods 53. A return spring 55 is sleeved on each guide rod 53, and the return spring 55 is extended and retracted along the sliding direction of the limit frame 54. The bottom of the return spring 55 is in conflict with the bottom wall of the guide rod 53, and the top of the return spring 55 is in conflict with the bottom wall of the limit frame 54. In a natural state, the return spring 55 is used to push the limit frame 54 to extend from the upper surface of the material transfer frame 50. When the limit frame 54 extends from the upper surface of the material transfer frame 50, the limit frame 54 will be located on the discharge path of the steel pipe.

[0032] When the cut steel pipe falls from the discharge port of the feed belt 40 to the transfer rack 50, the steel pipe will roll downward along the inclined transfer rack 50 under the action of its own gravity. In order to prevent the steel pipe from directly rushing out of the discharge port of the transition rack 51 due to excessively fast rolling speed, a limit rack 54 is provided at an appropriate position of the transfer rack 50 to block the steel pipe, thereby effectively preventing the steel pipe from directly rushing out of the discharge port of the transition rack 51. In addition, a certain transition time can be reserved for the rotation of the material-diverting fin 521 to ensure that the material-diverting fin 521 can block the steel pipe again. At the same time, the impact force generated when the steel pipe collides with the material-diverting fin 521 can be reduced, thereby reducing the bumps on the surface of the steel pipe and protecting the surface of the steel pipe.

[0033] like Figure 5 , Figure 6As shown, the cutting frame 1 is provided with a control assembly 7 for controlling the lifting and lowering of the limit frame 54 along the length direction of the guide rod 53. The control assembly 7 includes a through rod 70 fixedly mounted on the cutting frame 1, and the length direction of the through rod 70 is consistent with the rotation axis direction of the material transfer plate 520. The through rod 70 is rotatably provided with a plurality of swinging rods 71 ​​respectively located between the limit frame 54 and the material diverting fin 521, and the swinging rods 71 ​​are arranged in sequence along the length direction of the through rod 70, and the swinging rods 71 ​​correspond to the limit frame 54 one by one.

[0034] like Figure 5 , Figure 6 As shown, one end of the swing rod 71 is located on the rotation path of the adjacent material-diverting fin 521, and the other end of the swing rod 71 is movably arranged on the limit frame 54. When the material-diverting fin 521 pushes one end of the swing rod 71 to rotate upward around the through rod 70, the other end of the swing rod 71 will drive the respective limit frames 54 to move downward along the guide rod 53, and the return spring 55 will be gradually compressed, and finally the limit frames 54 will be moved out of the discharging path of the steel pipe, and then the steel pipe blocked by the limit frame 54 can continue to roll down from the material conveying frame 50.

[0035] like Figure 6 , Figure 7 As shown, a driving disc 56 located at one side of the waste collection bin 60 is rotatably provided on the conveyor platform 52, an eccentric plate 58 is fixedly provided on the driving disc 56, a push rod 59 is rotatably provided at the end of the eccentric plate 58, and the rotation axis of the push rod 59 is parallel to the rotation axis of the driving disc 56. One end of the push rod 59 away from its own rotation axis is rotatably connected to the respective opposite ends of the push rod 59, and the push rod 59 is used to drive the cleaning brush 601 to move back and forth on the surface of the waste filter 600. The driving disc 56 and the conveyor disc 520 are kept in synchronous rotation through a linkage 57. In this embodiment, the linkage 57 is a belt and a gear disc coaxially arranged on the rotation axis of the driving disc 56 and the conveyor disc 520, the belt is wound around the outside of the two gear discs, and the belt and the gear disc are meshed with each other.

[0036] like Figure 4 As shown, the polishing mechanism 2 includes a polishing table 20 located below the discharge port of the transition frame 51, and two groups of rollers 21 for driving the steel pipe to rotate are rotatably arranged on the polishing table 20, and the rollers 21 are driven to rotate by a motor. A screw rod 22 located below the two groups of rollers 21 is also rotatably arranged in the polishing table 20, and the length of the screw rod 22 extends along the length direction of the rollers 21. A discharge plate 23 is threadedly connected to the screw rod 22, and the discharge plate 23 is slidably arranged in the polishing table 20 along the length direction of the screw rod 22.

[0037] like Figure 4As shown, the top of the unloading plate 23 extends upward between the two groups of rollers 21, and the unloading plate 23 is used to periodically push the steel pipes between the rollers 21 to be alternately moved out from the left and right discharge ports of the polishing table 20. The polishing table 20 is also provided with two groups of polishing machines 24 driven by a motor, which are symmetrically arranged above the discharge ports on both sides of the polishing table 20, and the polishing machines 24 are used to polish the surface of the steel pipes on the rollers 21. The steel pipes are alternately polished by the polishing machines 24 on both sides, thereby further improving the unloading efficiency of the unloading plate 23 and reducing the unnecessary round trip time of the unloading plate 23.

[0038] The present application also provides a production process for a stainless steel seamless pipe, using the above-mentioned stainless steel seamless pipe processing equipment, including: S1. The steel pipe to be processed is placed on the feeding assembly 4, and the steel pipe to be cut is periodically transported to the rear cutting assembly 3 through the feeding assembly 4; S2. The steel pipe cut by the cutting assembly 3 will fall onto the material transfer rack 50 under the transmission of the feeding assembly 4; then the steel pipe will be limited at the specified position of the material transfer rack 50 under the blocking of the limiting rack 54; when the material shifting fin 521 pushes the steel pipe that falls on the transition rack 51 onto the polishing mechanism 2, at this time, under the drive of the control assembly 7, the limiting rack 54 will gradually move out of the discharging path of the steel pipe, and then the steel pipe will roll onto the transition rack 51 under the action of its own gravity, and the steel pipe will be limited on the transition rack 51 under the blocking of the rear material shifting fin 521; as the material shifting fin 521 passes over the swing rod 71, the limiting rack 54 will be lifted and reset under the elastic force of the reset spring 55, so that the cut steel pipe can be limited on the limiting rack 54 again; S3. The steel pipe that falls onto the polishing table 20 rotates under the joint drive of the rollers 21 on both sides, and then the polishing machine 24 is started to polish the surface of the steel pipe. At the same time, the unloading plate 23 will push the steel pipe to move to the polishing machine 24 in the specified direction under the drive of the screw 22.

[0039] The implementation principle is: after the nut fastener 300 is unscrewed from the end of the driving roller 30, the installation position of the cutting disc 31 can be adjusted by adjusting the number of adjusting rings 32 on both sides of the cutting disc 31, thereby meeting the cutting requirements of steel pipes of different lengths. When the push plate 42 pushes the steel pipe to gradually move to the bottom of the pressing plate 43, the steel pipe can be effectively prevented from tilting and falling from the feeding belt 40 during cutting under the limit of the pressing plate 43, thereby ensuring the stability of the steel pipe during cutting. After the cutting discs 31 on both sides complete cutting of the steel pipe, the steel pipe will be pushed out from the bottom of the pressing plate 43 by the push plate 42.

[0040] When the polishing mechanism 2 finishes polishing the steel pipe, the material-diverting fin 521 will rotate again, and the rear material-diverting fin 521 will push the steel pipe to be automatically added to the polishing mechanism 2. This cycle is repeated, which improves the processing efficiency of the steel pipe, reduces the number of times the steel pipe is transported, reduces the bumps that occur during the processing of the steel pipe, further improves the yield rate of the steel pipe, and reduces the safety hazards in the transportation process.

[0041] The cleaning brush 601 is driven to move on the surface of the waste filter 600 by pushing the connecting rod 602. At this time, under the action of the cleaning brush 601, the waste remaining on the surface of the waste filter 600 can be swept into the cavity below the waste filter 600, and the steel pipe waste will be moved into the waste collection bin 60 under the push of the cleaning brush 601, thereby achieving the purpose of screening the steel pipe waste and waste.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
