[0046] Two groups of limiting mechanisms 9, the two groups of limiting mechanisms 9 are respectively arranged between the two groups of object carrying mechanisms 8 and the two groups of shaft sleeves 3;

[0047] In use, the driving mechanism 5 drives the misalignment mechanism 7 to rotate, the misalignment mechanism 7 drives the carrier mechanism 8 to rotate, the pulling mechanism 6 drives the two misalignment mechanisms 7 to move close to or away from each other, and the two misalignment mechanisms 7 drive the two carrier mechanisms 8 to move close to or away from each other. When the two misalignment mechanisms 7 move away from each other, the misalignment mechanism 7 pulls the carrier mechanism 8 to extrude the limiting mechanism 9 to shrink inward.

[0048] As shown in Figure 1 and Figure 2 , the cutting mechanism 4 includes two groups of first driving members 401, which are symmetrically and fixedly installed on the sides away from each other of the two groups of support plates 2. The output ends of the two groups of first driving members 401 are connected with a rotating shaft 402, which is movably sleeved in the middle of the shaft sleeve 3. The middle of the rotating shaft 402 is fixedly sleeved with a cutting disc 403. The two first driving members 401 are the same type of motors and work synchronously and are connected with the same rotating shaft 402.

[0049] The contact surfaces of the rotating shaft 402 and the shaft sleeve 3 are smooth surfaces. The rotating shaft 402 and the shaft sleeve 3 are made of materials with high thermal conductivity. The rotating shaft 402 and the shaft sleeve 3 are made of copper alloy, thereby reducing the frictional resistance when the rotating shaft 402 rotates along the inner curved surface of the shaft sleeve 3, reducing the load of the first driving member 401, reducing the heat generated by the friction when the rotating shaft 402 and the shaft sleeve 3 rotate, avoiding high-temperature deformation of the rotating shaft 402 and the shaft sleeve 3, and improving the service life of the rotating shaft 402 and the shaft sleeve 3.

[0050] In use, the output end of the first driving member 401 drives the rotating shaft 402 to rotate, the rotating shaft 402 drives the cutting disc 403 to rotate, and the cutting disc 403 cuts the metal pipe in contact with it.

[0051] As shown in Figure 1 , the driving mechanism 5 includes a second driving member 501, which is fixedly installed on the front of the upper surface of the base 1. The output end of the second driving member 501 is connected with a commutator 502 on the right side. The commutator 502 is fixedly connected with the base 1. The left side of the output end of the second driving member 501 and the right side of the output end of the commutator 502 are both fixedly connected with a tooth column 503. Two support seats 504 are symmetrically and fixedly installed on the left side of the upper surface of the base 1. The tooth column 503 is movably sleeved in the middle of the support seat 504.

[0052] The second driving member 501 adopts a low-speed progressive motor, so as to improve the rotation accuracy of the second driving member 501, avoid that the central axes of the left and right two groups of inner sleeves 805 obviously deviate after the driving mechanism 5 drives the two groups of misplacement mechanisms 7 to rotate in opposite directions for multiple times, and cause that the metal pipe in the middle of the left inner sleeve 805 cannot be inserted into the middle of the right inner sleeve 805 and the metal pipe in the middle of the right inner sleeve 805 cannot be inserted into the middle of the left inner sleeve 805. Further, the number of teeth of the tooth column 503 is less than the number of teeth of the tooth disc 701, so as to further reduce the rotation error of the tooth column 503 and improve the alignment accuracy of the central axes of the left and right inner sleeves 805.

[0053] In use, the output end on the left side of the second driving member 501 drives the tooth column 503 on the left side to rotate forward, the output end on the right side of the second driving member 501 drives the input end of the reversing device 502 to rotate forward, and the output end of the reversing device 502 drives the tooth column 503 on the right side to rotate reversely, so as to realize the opposite rotation of the tooth columns 503 on the left and right sides, and the opposite rotation of the two groups of tooth discs 701 engaged with the two groups of tooth columns 503, so as to realize the opposite rotation of the two groups of misplacement mechanisms 7 driven by the driving mechanism 5.

[0054] Please refer to Figures 2 to 4 As shown in the figure, the pulling mechanism 6 comprises a fixed seat 601 fixedly installed in the middle of the guide groove 101, and the left and right sides of the fixed seat 601 are symmetrically fixedly installed with hydraulic rods 602, and the extension ends of the two groups of hydraulic rods 602 are fixedly installed with sliding seats 603, and the sliding seats 603 are slidingly sleeved with the guide groove 101;

[0055] The contact surfaces of the sliding seats 603 and the guide groove 101 are smooth surfaces, so as to reduce the friction resistance between the fixed seat 601 and the guide groove 101 and reduce the load of the fixed seat 601;

[0056] In use, when the extension ends of the two groups of fixed seats 601 are simultaneously retracted, the output ends of the two groups of fixed seats 601 respectively drive the sliding seats 603 fixedly connected thereto to move towards the fixed seat 601, and the two groups of sliding seats 603 drive the two groups of tooth discs 701 slidingly sleeved therewith to move close to each other, and vice versa, when the extension ends of the two groups of fixed seats 601 are simultaneously extended, the output ends of the two groups of fixed seats 601 respectively drive the sliding seats 603 fixedly connected thereto to move away from the fixed seat 601, and the two groups of sliding seats 603 drive the two groups of tooth discs 701 slidingly sleeved therewith to move away from each other, so as to realize that the pulling mechanism 6 drives the misplacement mechanisms 7 to move close to or away from each other.

[0057] Please refer to Figures 1 to 5As shown, the dislocation mechanism 7 comprises a toothed disc 701, which is slidingly sleeved on the shaft sleeve 3 near the side of the support plate 2, slidingly sleeved on the middle part of the sliding seat 603, and a plurality of push rods 702 are fixedly sleeved on the left circumferential surface of the toothed disc 701 at equal intervals, and a sliding sleeve 703 is fixedly installed on the side of the toothed disc 701 away from the support plate 2, which is slidingly sleeved with the shaft sleeve 3, and a plurality of sliding grooves 704 are formed on the curved circumferential surface of the sliding sleeve 703 at equal intervals.

[0058] The contact surface between the toothed disc 701 and the sliding seat 603 is a smooth surface, so as to reduce the friction resistance when the sliding seat 603 drives the toothed disc 701 to rotate and slide left and right, slow down the wear of the sliding seat 603 and the toothed disc 701, and improve the service life of the sliding seat 603 and the toothed disc 701.

[0059] The central axis of the push rod 702 coincides with the central axis of the inner sleeve 805 adjacent thereto, and the diameter of the push rod 702 is smaller than the inner hole diameter of the inner sleeve 805, so that when the sliding sleeve 703 drives the push rod 702 to slide towards the limiting mechanism 9 through the toothed disc 701, the toothed disc 701 drives the push rod 702 to insert into the middle part of the inner sleeve 805, and when the inner sleeve 805 is sleeved with a metal pipe, the push rod 702 pushes a part of the metal pipe in the middle part of the inner sleeve 805 to insert into the middle part of the other inner sleeve 805, so that the two adjacent inner sleeves 805 on the left and right sides simultaneously clamp a metal pipe.

[0060] Please refer to Figure 1 、 Figures 3 to 5 As shown, the object carrying mechanism 8 comprises a plurality of first sliding blocks 801, which are slidingly sleeved in the middle part of the plurality of sliding grooves 704 respectively, a curved rod 802 is slidingly sleeved on the side of the first sliding block 801 away from the shaft sleeve 3, a rotating seat 803 is movably sleeved on the end of the curved rod 802 away from the first sliding block 801, an outer sleeve 804 is fixedly installed on the side of the rotating seat 803 away from the shaft sleeve 3, and an inner sleeve 805 is fixedly sleeved on the middle part of the outer sleeve 804.

[0061] The inner sleeve 805 is made of rubber material with an inner hole diameter smaller than the outer diameter of the metal pipe, so as to increase the friction resistance between the metal pipe and the inner sleeve 805, avoid relative sliding between the metal pipe and the inner sleeve 805 when the cutting disc 403 cuts the metal pipe, cause the cutting position of the metal pipe to deviate, reduce the cutting precision, and reduce the noise generated when the cutting disc 403 cuts the metal pipe.

[0062] Please refer to Figures 3 to 5As shown, the limiting mechanism 9 comprises a fixed ring 901 fixedly sleeved on the side of the shaft sleeve 3 away from the support plate 2, a plurality of sleeves 902 are fixedly installed on the side of the fixed ring 901 away from the shaft sleeve 3 at equal intervals in the circumference, the elastic members 903 are fixedly installed on the inner cavities of the sleeves 902 close to the fixed ring 901, the sleeve rods 904 are fixedly installed on the side of the elastic members 903 away from the fixed ring 901, the sleeve rods 904 are slidingly sleeved with the sleeves 902, and the sleeve rods 904 are fixedly connected with the outer sleeves 804 at the ends thereof away from the fixed ring 901.

[0063] In use, when the pulling mechanism 6 pushes the staggered mechanism 7 to move away from the limiting mechanism 9, at this time, the sliding sleeve 703 moves away from the limiting mechanism 9, when the first sliding block 801 contacts the sliding groove 704 at the end close to the limiting mechanism 9, the sliding groove 704 pulls the first sliding block 801 to move away from the limiting mechanism 9, at this time, the first sliding block 801 pulls the outer sleeve 804 to move towards the shaft sleeve 3 through the curved rod 802 and the rotating seat 803, the inner sleeve 805 drives the sleeve rod 904 to compress the elastic member 903 to shrink towards the shaft sleeve 3, so that the plurality of rotating seats 803 shrink towards the shaft sleeve 3, in addition, when the pulling mechanism 6 pulls the staggered mechanism 7 to move towards the limiting mechanism 9, at this time, the sliding sleeve 703 moves towards the limiting mechanism 9, the elastic member 903 pushes the sleeve rod 904 to move away from the shaft sleeve 3, so that the outer sleeve 804 resets away from the shaft sleeve 3.

[0064] Working principle:

[0065] In use, the left hydraulic rod 602 is first started in the forward direction, the telescopic end of the left hydraulic rod 602 is extended, the left hydraulic rod 602 pushes the left staggered mechanism 7 to move away from the cutting disc 403 through the sliding seat 603, at this time, the left staggered mechanism 7 drives the left carrying mechanism 8 to shrink inward, the left carrying mechanism 8 compresses the left limiting mechanism 9 connected thereto to shrink, so that the outer sleeve 804 of the left carrying mechanism 8 is located inside the outer sleeve 804 of the right carrying mechanism 8, so as to realize that a metal pipe to be cut is inserted into the middle part of the inner sleeve 805 in the inner cavity of the uppermost outer sleeve 804 of the right carrying mechanism 8.

[0066] Then the left hydraulic rod 602 resets, at this time the left load mechanism 8 resets under the action of the left limiting mechanism 9, at this time the middle axes of the left and right adjacent inner sleeves 805 coincide, then the left and right hydraulic rods 602 are synchronously and reversely started, the telescopic ends of the left and right hydraulic rods 602 retract, at this time the pulling mechanism 6 drives the two sets of staggered mechanisms 7 to move towards each other, the two sets of downward moving staggered mechanisms 7 drive the push rods 702 to respectively insert into the middle parts of the inner sleeves 805 adjacent thereto, at the same time, because the two sets of push rods 702 move towards each other by the same distance, at this time the two sets of push rods 702 push the movement of the middle parts of the inner sleeves 805, so that the center of the metal pipe moves to the center positions of the left and right outer sleeves 804, then the cutting mechanism 4 is started to make the cutting disc 403 rotate, and then the two sets of hydraulic rods 602 are synchronously and forwardly started, the telescopic ends of the two sets of hydraulic rods 602 extend out, at this time the pulling mechanism 6 drives the two sets of staggered mechanisms 7 to move away from each other, until the push rods 702 leave the inner cavities of the inner sleeves 805, the two sets of staggered mechanisms 7 drive the two sets of load mechanisms 8 to synchronously retract inward, the load mechanisms 8 drive the metal pipe to contact the rotating cutting disc 403, and the cutting disc 403 cuts the metal pipe into two segments;

[0067] After the metal pipe is cut into two segments, the driving mechanism 5 is started, the driving mechanism 5 drives the two sets of staggered mechanisms 7 to rotate in the opposite direction, the two sets of staggered mechanisms 7 drive the two sets of load mechanisms 8 to rotate in the opposite direction, so that the metal pipes cut into two segments in the middle parts of the left and right inner sleeves 805 respectively move to the front side of the left load mechanism 8 and the rear side of the right load mechanism 8, at this time, by the same reason, the two sets of hydraulic rods 602 are reversely started, the telescopic ends of the two sets of hydraulic rods 602 retract, the pulling mechanism 6 drives the two sets of staggered mechanisms 7 to move towards each other, at this time, the left and right push rods 702 moving towards each other push the two segments of the metal pipes in the middle parts of the front and rear inner sleeves 805 to move in the direction of the cutting disc 403, so that the centers of the front and rear two segments of the metal pipes respectively move to the center positions of the front two sets of inner sleeves 805 and the rear two sets of inner sleeves 805, then the two sets of hydraulic rods 602 are forwardly started, at this time the pulling mechanism 6 drives the two sets of staggered mechanisms 7 to move away from each other, the two sets of staggered mechanisms 7 drive the two sets of load mechanisms 8 to retract, the load mechanisms 8 drive the two segments of the metal pipes to contact the rotating cutting disc 403, and the cutting disc 403 cuts the two segments of the metal pipes into four segments, and so on, so as to realize that the metal pipe is cut into multiple segments of the same length every time in the multiples of the number of the metal pipe cut in the previous time, and also realizes that the multiple segments of the metal pipe are clamped every time in the multiples of the number of the metal pipe clamped in the previous time, so as to realize the rapid batch cutting and clamping of the metal pipe, and realize that a metal pipe is rapidly batch cut into multiple short metal pipes.
