The initial steps are as follows:
Firstly, an operator needs to adjust the cutting length of the end head according to the size of the batch of steel pipes, and in the adjustment process, the threaded rod 902 needs to be rotated, so that the threaded rod 902 is screwed out of the clamping plate 6 and drives the sliding block 901 to move, the sliding block 901 stably moves towards one end of the supporting plate 2 under the sliding connection of the limiting rod II 903 and the clamping plate 6, and the position adjustment of the limiting block 904 fixedly connected with the sliding block 901 is driven, so that one end of a cutting part can be contacted with the two limiting blocks 904 in the cutting process of the steel pipes, and the cutting part of the steel pipes can be fixed at a uniform distance;
When an operator places the steel pipe on the two clamping plates 6, the steel pipe is pushed towards the supporting plate 2, so that the steel pipe moves towards the supporting plate 2 more conveniently and stably under the guide of the roller 8 on the two clamping plates 6, in the moving process, the steel pipe downwards presses the two clamping plates 6 under the action of gravity, so that the top of the two clamping plates 6 slowly increases from a minimum angle, when the steel pipe moves onto the clamping plates 6 entirely and is attached to the limiting block 904, the steel pipe is completely positioned on the two clamping plates 6, the mounting rod I1105 and the mounting rod II 1106 at the bottom are positioned on the inner side of the steel pipe, the two clamping plates 6 are fixed after the supporting angle is unfolded under the balance of the elastic acting force of the spring I506 and the gravity of the steel pipe, in the supporting angle unfolding process of the top of the clamping plates 6, the two clamping plates 6 can drive the mounting shaft 7 to downwards move, the slide seat 501 which is rotationally connected with the connecting seat 502 through the connecting shaft 503 moves towards one end far away from the fixed block 504, the slide seat 501 is limited and supported by the first limiting rod 505 in the moving process, the first spring 506 is compressed while the moving stability is ensured, the first spring 506 is prevented from deflection in the compressing and resetting process to affect the service life through the first limiting rod 505, when the elastic stretching force of the first spring 506 is equal to the gravity of the steel tube, the steel tube can complete the supporting installation on the two clamping plates 6, the movement of the movable seat 1101 can still be completed in different sizes through the installation shaft 7, the installation shaft 7 can enable the ball screw 1204 and the bidirectional worm 1205 to synchronously move downwards in the downward moving process of the movable seat 1101, the downward movement of the ball screw 1204 can drive the movable plate 1103 to synchronously move downwards, the movable plate 1103 moves to drive the movable block 1102 to move downwards through the second mounting rod 1106, so that synchronous movement of the whole clamping assembly is realized, and the clamping assembly can clamp and drive steel pipes with different sizes along with the movement of the clamping plate 6;
After the steel pipe is placed and supported on the two clamping plates 6, the motor 4 is started, so that the output shaft of the motor 4 rotates positively and drives one driving shaft 1201 to rotate, because the diameter of the driving wheel III 1202 is twice that of the driving wheel IV 1203, the driving shaft 1201 can drive the three driving shafts 1201 to rotate synchronously through the transmission connection of the driving wheel III 1202, the driving wheel IV 1203 and the driving belt II 1209, the rotation of the driving shafts 1201 drives the clamping blocks 1207 to rotate synchronously, because the clamping blocks 1207 are clamped on the inner sides of the ball screw 1204 and the two-way worm 1205 under the stretching elastic force of the spring III 1208, the sliding of the ball screw 1204 and the two-way worm 1205 on the outer sides of the driving shafts 1201 is not influenced, the driving shafts 1201 can not drive the ball screw 1204 and the two-way worm 1205 through the clamping blocks 1207, when the ball screw 1204 and the two-way worm 1205 rotate, one ball screw 1204 drives the top movable plate 1103 to move downwards, and the other ball screw 1204 drives the bottom movable plate 1103 to move upwards due to the symmetrical arrangement, the opposite movement of the two movable plates 1106 can drive the two movable blocks 1102 to move oppositely, and the two movable blocks 1102 are contacted with the inner walls of the motor output shaft of the worm wheel 1208 under the stretching elastic force of the spring III 1208, the first clamping rod and the second clamping rod is kept in contact with the inner wall of the motor output shaft of the motor, and the two ends of the two steel pipe can be continuously installed on the two steel pipe rod and can be installed and meshed with the two cutting rods and can rotate in a stable way, and can be continuously and rotatably mounted with the two steel pipe rod is installed;
When the steel pipe with larger size and gravity is placed on the clamping plate 6, the steel pipe can extrude the rubber disc 1003 to deform under the action of gravity and realize the fit between the two, and when the installation rod II 1106 rotates, the rotation of the fixing rod 1001 can be realized through the transmission connection of the transmission wheel I1004, the transmission wheel II 1005 and the transmission belt I1006, the fixing rod 1001 drives the rubber disc 1003 to synchronously rotate through the fixing disc 1002, and the rotating rubber disc 1003 can drive the steel pipe to rotate, so that the auxiliary rotating function is realized, and the rotating stability of the steel pipe with larger size and gravity is ensured.
