Every time when the rolling cylinders 9 move rightwards, the seamless steel tube 101 is required to move rightwards for a certain distance to ensure the continuity of the cold rolling process, the seamless steel tube 101 is required to rotate when the seamless steel tube 101 moves rightwards to ensure the extrusion uniformity of the seamless steel tube 101, in the process of reciprocating movement of the two rolling cylinders 9, if the extrusion force of the rolling cylinders 9 to the seamless steel tube 101 is overlarge, the seamless steel tube 101 cannot be fully stretched after being extruded by the two rolling cylinders 9, the surface of the seamless steel tube 101 is wrinkled when serious, if the extrusion force of the rolling cylinders 9 to the seamless steel tube 101 is overlarge, the efficiency of cold rolling the seamless steel tube 101 by the rolling cylinders 9 is reduced, therefore, the pressure between the rolling cylinders 9 and the seamless steel tube 101 is required to be regulated, and the change rate of the middle diameter of the outer side surface of the rolling cylinders 9 cannot be changed, when the interval between two pricking cylinders 9 is fixed, and the two pricking cylinders 9 extrude the seamless steel pipe 101, the distance from the middle part of the outer side surface of the pricking cylinder 9 to the seamless steel pipe 101 is uniformly changed, when the pressure of the two pricking cylinders 9 to the seamless steel pipe 101 is overlarge in the initial state, the pressure of the two pricking cylinders 9 to the seamless steel pipe 101 is always larger in the process of contacting with the seamless steel pipe 101, therefore, when the pressure of the two pricking cylinders 9 to the seamless steel pipe 101 is larger, the interval between the two pricking cylinders 9 needs to be gradually increased in the process of moving from right to left, and the distance from the middle part of the outer side surface of the pricking cylinder 9 to the seamless steel pipe 101 is reduced more slowly, and meanwhile, the pressure of the two pricking cylinders 9 to the seamless steel pipe 101 is gradually reduced, and the specific operation is as follows:
when the pressure of two pricking cylinders 9 to the seamless steel tube 101 is increased, the pressure of the pricking cylinders 9 is transmitted to the pressure sensor 601 through the rotating shaft 8 and the extrusion block 7, the pressure sensor 601 sends signals to the control terminal, the control terminal starts the left servo motor 2, the output shaft of the left servo motor 2 drives the left two threaded rods 3 to rotate through gears, the threaded rods 3 drive the two threaded sleeves 4 on the threaded rods to be far away from each other, the control terminal closes the left servo motor 2 until the pressure detected by the pressure sensor 601 is a normal value, at the moment, the left side of the upper rectangular frame 5 is higher than the right side, the left side of the lower rectangular frame 5 is lower than the right side, when the two pricking cylinders 9 move leftwards, the distance between the two pricking cylinders 9 is increased, so that the pressure of the pricking cylinders 9 to the seamless steel tube 101 is reduced, and in conclusion, the moving path of the two pricking cylinders 9 is adjusted by detecting the pressure of the two pricking cylinders 9 to the seamless steel tube 101, and the pressure of the pricking cylinders 9 to the seamless steel tube 101 is ensured to be in a constant value.
In the process that the fixed column 1205 drives the connecting rod 1206 to move, when the fixed column 1205 is positioned at the left side or the right side of the turntable 1204, the parts on the bundling barrel 9 generate inertia, so that the first rotating rod 1203 is stressed unevenly, and therefore the eccentric impact force born by the first rotating rod 1203 needs to be balanced when the fixed column 1205 is positioned at the left side or the right side of the turntable 1204.
In the cold rolling process of the seamless steel tube 101, the reciprocating speed of the rolling tube 9 needs to be adjusted for different seamless steel tubes 101, when the reciprocating speed of the rolling tube 9 is increased, the transverse impact force generated by the rolling tube 9 is also increased, so that the position of the balancing weight 1302 needs to be adjusted, the balancing weight 1302 is far away from the first rotating rod 1203, the centrifugal force borne by the balancing weight 1302 is increased, and more eccentric force of the first rotating rod 1203 is balanced, and the specific operation is as follows: when the rotation speed of the first rotating rod 1203 increases, the centrifugal force applied to the sliding block 1403 increases, the spring in the second sleeve 1401 is compressed, taking fig. 8 as an example, the sliding block 1403 drives the first L-shaped rod 1402 to move rightward, when the first L-shaped rod 1402 slides along the inclined portion of the sliding rod 1307 chute, the first L-shaped rod 1402 drives the sliding rod 1307 to rotate counterclockwise, the sliding rod 1307 drives the second baffle plate 1308 to rotate counterclockwise, when the first L-shaped rod 1402 is located at the junction of the inclined portion of the sliding rod 1307 chute and the transverse portion, the through hole of the second baffle plate 1308 is communicated with the through hole of the first baffle plate 1305, at this time, the right side of the first baffle plate 1305 in the first sleeve 1303 is no longer in a sealed state, the balancing weight 1302 is separated from the first rotating rod 1203 by centrifugal force, and simultaneously the balancing weight 1302 drives the first baffle plate 1305 to move rightward through the guide block 1301, the connecting plate 1306 and the sliding sleeve 1304 drives the second baffle plate 1308 to move rightward through the sliding rod 1307, when the distance between the weight 1302 and the first rotating rod 1203 increases, the centrifugal force applied to the weight 1302 increases, the eccentric force applied to the first rotating rod 1203 balanced by the weight 1302 increases, when the centrifugal force applied to the sliding block 1403 is equal to the elastic force of the spring in the second sleeve 1401, the sliding block 1403 is no longer moved rightward, the first L-shaped rod 1402 is located at the junction of the inclined portion and the transverse portion of the slide bar 1307, and as the slide bar 1307 continues to move rightward, when the inclined portions of the first L-shaped rod 1402 and the slide bar 1307 are engaged, the through hole of the second retaining disc 1308 and the through hole of the first retaining disc 1305 are displaced, the right side of the first retaining disc 1305 in the first sleeve 1303 is in a sealed state again, the first retaining disc 1305 is no longer moved rightward, the weight 1302 is no longer moved rightward, and as described above, when the reciprocating speed of the bundling drum 9 increases, so that the balancing weight 1302 balances the eccentric force applied by the first rotating rod 1203, and ensures the normal operation of the first rotating rod 1203.
After the cold rolling of the seamless steel tube 101 is completed, the control terminal stops the gear motor 1202, an operator takes down the seamless steel tube 101, and the tube bundling machine is completed.
