The fixed setting of shell 2 is on base 1, before the use, need put into rough machining device 31 with the one end of crooked steel pipe, start the automatic straightening machine afterwards, rough machining device 31 just can start this moment, rough machining device 31 can carry out preliminary alignment with crooked steel pipe, but because can not guarantee that the perisporium of steel pipe is even all the time when rough machining device 31 aligns the steel pipe, this situation that the steel pipe is not the cylinder of standard after being aligned will appear. The primary processing device 31 can also drive the steel pipe to move along the length direction of the base 1 while straightening the steel pipe. In the longitudinal direction of the base 1, a rough machining device 31, a recognition device 32, a finish machining device 35, and a cylindrical profile machining device 36 are arranged from one end of the steel pipe entering the inside of the housing 2. When the steel pipe moved along the length direction of base 1 under the drive of rough machining device 31, the steel pipe can pass through identification device 32 one side, and identification device 32 can discern the steel pipe that passes through, and identification device 32 can send the signal to the controller afterwards, and the controller can start finish machining device 35. Before finishing device 35 is started, the steel pipe can enter into finishing device 35 earlier, after finishing device 35 is activated, drive arrangement 34 also can be activated in step, so drive arrangement 34 just can drive finishing device 35 and cliies the steel pipe, finishing device 35 can make the steel pipe can also make steel pipe self take place to rotate when moving along the length direction of base 1, along with finishing device 35's continuous operation, the steel pipe that rotates and remove can enter into cylindrical shape processingequipment 36, because the steel pipe is in the pivoted state, the outside lateral wall of steel pipe can fully contact with cylindrical shape processingequipment 36, if the outside lateral wall of steel pipe is inhomogeneous, when the outside of steel pipe is not standard cylindrical structure, the steel pipe just can be corrected by cylindrical shape processingequipment 36, thereby make the external shape of steel pipe processed into standard cylindrical structure, the steel pipe just can be discharged by cylindrical shape processingequipment 36 afterwards, so realized the processing to the steel pipe. The device can straighten steel pipes with various sizes and can also convey the steel pipes, so that the cylindrical appearance of the steel pipes and the machining efficiency of the steel pipes are guaranteed.
As shown in fig. 2 and fig. 8-11: the finishing device 35 comprises a rotating disc 351, a protruding block 352, an auxiliary wheel 353, a placing seat 354, a first pressing wheel 355, a resetting assembly 356, a first rotary driver 357 and a pressure sensing assembly 358; the rotating disc 351 is rotatably arranged on one side of the bracket 33, and a through groove is arranged in the rotating disc 351 in a penetrating way along the axis of the rotating disc; a plurality of convex blocks 352 are arranged, the convex blocks 352 are uniformly and fixedly arranged on the inner wall of the through groove around the axis of the through groove, and one side of the convex block 352, which is far away from the side wall of the through groove, is gradually close to the center of the through groove from one end of the convex block 352; the pressure sensing assembly 358 is arranged on the side of the protruding block 352 away from the through slot; the placement seat 354 is arranged on the side of the pressure sensing assembly 358 away from the convex block 352; the auxiliary wheel 353 can be rotatably arranged on the placing seat 354, and the auxiliary wheel 353 is in rolling fit with the pressure sensing assembly 358; the restoring assembly 356 is disposed on a side of the placing seat 354 away from the axis of the rotating disk 351 in the radial direction of the rotating disk 351; the first rotary actuator 357 is fixedly arranged on the placing seat 354; the first pressing wheel 355 is fixedly arranged on the output end of the first rotary driver 357, and the included angle between the axis of the first pressing wheel 355 and the axis of the steel pipe is smaller than 90 degrees.
The first rotary actuator 357 is preferably a servo motor, and when the steel pipe has not passed the identification device 32, the reset assembly 356 is not activated and the auxiliary wheel 353 is located at the end of the projection 352 remote from the centre of the through slot. After the steel pipe passes through the recognition device 32 and is recognized by the recognition device 32, the recognition device 32 starts the driving device 34, the driving device 34 drives the rotating disc 351 to rotate, and the protruding block 352 is fixedly arranged on the side wall of the through groove, so when the rotating disc 351 rotates, the protruding block 352 also rotates along with the rotating disc, and as the protruding block 352 is always in contact with the auxiliary wheel 353, along with the rotation of the rotating disc 351, the protruding block 352 gradually enables the auxiliary wheel 353 to approach the center of the rotating disc 351, so that the placing seat 354 drives the first pressing wheel 355 to approach the center of the rotating disc 351. After the steel pipe passes through the recognition device 32, the steel pipe passes through the through-groove. Under the continuous drive of drive arrangement 34, first suppression wheel 355 finally can contact with the steel pipe, and first rotatory driver 357 can drive first suppression wheel 355 afterwards and rotate, because the contained angle between the axis of first suppression wheel 355 and the axis of steel pipe is less than 90 degrees, so after first suppression wheel 355 is driven rotatoryly by first rotatory driver 357, first suppression wheel 355 can produce the driving force of an slope to the lateral wall of steel pipe, the tilting force can make the steel pipe can also move along the length direction of base 1 when the pivoted. It should be noted that, when the protruding block 352 drives the auxiliary wheel 353 so that the placing seat 354 is close to the center of the through groove, the resetting component 356 is activated, but due to the limitation of the protruding block 352, the resetting component 356 cannot reset the placing seat 354, but after the driving device 34 drives the rotating disc 351 to rotate reversely, the protruding block 352 on the rotating disc 351 can rotate reversely, so that the resetting component 356 can ensure that the auxiliary wheel 353 is always in contact with the side wall of the protruding block 352, and further the placing seat 354 is gradually far away from the center of the through groove, if the finishing device 35 is provided with a plurality of parts, preliminary cylindrical appearance processing can be performed on the outer side of the steel pipe. The pressure sensing assembly 358 is used for monitoring the pressure value of the first pressing wheel 355 on the steel pipe, and when the pressure value of the first pressing wheel 355 reaches the maximum preset value, the first rotary driver 357 stops rotating, so that the load of the first rotary driver 357 is not too large, and the first rotary driver 357 is prevented from being damaged.
As shown in fig. 8 and 9: the pressure sensing assembly 358 comprises a spring plate 3581 and a pressure sensor 3582; the pressure sensor 3582 is fixedly arranged on the side wall of the protruding block 352 far away from one side of the through groove; the elastic piece 3581 is arranged on one side of the pressure sensor 3582 far away from the convex block 352, and one end of the elastic piece 3581 is fixedly connected with the convex block 352.
