When the port synchronous fixing ring 5 clamps the port of the outer pipe, the opening and closing driving motor 6 is started and the output end of the opening and closing driving motor is controlled to rotate, so that the motor shaft linkage 532 in transmission connection with the opening and closing driving motor is driven to rotate synchronously, and then the screw thread tightening rotary cylinder 531 is driven to rotate synchronously through the motor shaft linkage 532, so that the screw thread tightening rotary cylinder 531 continuously moves towards the rear of the pipe thread aligning cylinder 51 under the action of the screw thread arranged on the outer side of the pipe thread aligning cylinder 51.
In the process that the thread tightening rotary cylinder 531 moves towards the rear of the pipe and wire aligning cylinder, the pulling rotary disc 512 which is rotatably connected with the thread tightening rotary cylinder is driven to move towards the rear, so that the pulling rotary disc 512 drives the corresponding stroke rail clamping blocks 522 to synchronously move towards the rear of the interior of the pipe and wire aligning cylinder 51 along the stroke tightening slide rail 521 through the clamping block transmission connecting rods 513, and in the process that the stroke rail clamping blocks 522 move towards the rear along the stroke tightening slide rail 521, the distance between the stroke rail clamping blocks 522 is gradually reduced, so that a long pipe extending into the pipe and wire aligning cylinder 51 is clamped by the stroke rail clamping blocks 522 in a matching manner.
When the open-close type split frame 33 at two ends of the bearing rolling lap joint mechanism 32 is closed, the elastic bolts 344 on the two groups of open-close type split frames 33 are screwed in the open-close type split frame 33 through the elastic bolts 344, so that the clamping sleeve inclined pressing block 341 moves towards the central position of the main lap ring section 322 along the open-close type split frame 33 until the primary and secondary butting frames 343 at the adjacent sides of the two secondary lap ring sections 342 are mutually clamped, and the two primary and secondary butting frames 343 at the opposite sides of the two secondary lap ring sections 342 are clamped in the clamping sleeve vertical holding frames 3221 at two sides of the main lap ring section 322, so that the main lap ring section 322 and the two secondary lap ring sections 342 are butted to form an annular structure for extruding a long pipe, and then the pressure regulating clamping sleeve mechanism 3 installed on the clamping sleeve power rail 7 is moved by controlling the telescopic device on the clamping sleeve power rail 7 to move the pressure regulating tightening mechanism 3 along the direction in which the long pipe extends, and the long pipe is squeezed and tightened in the moving process.
And in the process of butt joint, the difficulty of butt joint with the primary and secondary butt joint frames 343 is reduced by the butt joint frame guide groove 3222 on the ferrule vertical holding frame 3221, and after the butt joint is completed, the primary and secondary butt joint frames 343 ensure the overall perpendicularity of the two secondary lap joint ring segments 342 and the primary lap joint ring segment 322 through the butt joint frame guide groove 3222 on the ferrule vertical holding frame 3221.
Because the outer side of the main lapping ring section 322 is sleeved with the wear-resistant ring section sleeve 324 which is rotationally connected with the main lapping ring section 322, and the wear-resistant ring section sleeve 324 replaces the main lapping ring section 322 to be in contact with the long pipe, in the moving process of the pressure regulating and tightening sleeve mechanism 3, the friction force between the main lapping ring section 322 and the long pipe is reduced when the wear-resistant ring section sleeve 324 rotates along the outer side of the main lapping ring section 322 under the friction force of the long pipe, so that the annular structure formed by the main lapping ring section 322 and the two auxiliary lapping ring sections 342 can extrude and.
And because the direction that cutting ferrule mechanism 3 was tightened up in the pressure regulating moves is opposite with the solid fixed ring 5 of port synchronization, consequently the cutting ferrule mechanism 3 is tightened up in the pressure regulating moves the centre gripping that the extrusion tightened up the in-process external pipe received the solid fixed ring 5 of port synchronization all the time, and the inside long filament stress degree of long tube is less, consequently the long tube is after the extrusion is tightened up, after the cutting piece through starting axle type cutting device 2 removes the cutting, long tube and long filament both ends port parallel and level, the wiring mode precision of short outside the interior length of relatively conventional is higher.
