When the second elastic member 3 is compressed and deformed, the second elastic member 3 is used to abut against the inner wall of the pipe.

[0029] The cutting device further includes a linear motion mechanism 10, a first support and limit seat 8 and a second support and limit seat 9. The second support assembly 33 is driven to perform a horizontal linear motion through the linear motion mechanism 10, thereby driving the second elastic member 3 to perform a horizontal linear motion; both the first support and limit seat 8 and the second support and limit seat 9 are used to support the pipe. The first support and limit seat 8 is located below the first elastic member 2, and a groove structure adapted to the pipe is provided on the first support and limit seat 8; the second support and limit seat 9 is located below the second elastic member 3, the second support and limit seat 9 corresponds to the clamping assembly 41 in position, and a groove structure adapted to the pipe is also provided on the second support and limit seat 9; the linear motion mechanism 10, the first support and limit seat 8, the second support and limit seat 9, the first support assembly 23, the second support assembly 33, the first lifting assembly 4 and the second lifting assembly 5 can all be installed on the same platform or a frame (not shown in the figure).

[0030] A limit ring 11 is embedded in the support seat 1, and one end of the pipe is used to abut against one end face of the limit ring 11.

[0031] The first elastic member 2 includes a horizontally arranged first spring 21. A first elastic spiral sleeve 22 is fixedly sleeved on a section of the first spring 21 adjacent to the second elastic member 3. The first elastic spiral sleeve 22 is made of rubber or silica gel. To facilitate the cooperation between the first elastic spiral sleeve 22 and the first spring 21, the first elastic spiral sleeve 22 can be arranged in two or more parts, and each part can be spliced by bonding or other means.

[0032] The first support assembly 23 includes a first connecting seat 232. One end of the first spring 21 and the first elastic spiral sleeve 22 adjacent to the second elastic member 3 are both fixedly connected to the first connecting seat 232. The first support assembly 23 further includes a first support column 231. One end of the first support column 231 is fixedly connected to the first connecting seat 232, and the other end of the first support column 231 is fixedly arranged on the support seat 1. The first support column 231 is horizontally arranged and passes through the limiting ring 11. In addition, the central axis of the first spring 21 is collinear with the axis of the first support column 231.

[0033] The driving assembly 6 includes a first guiding cylinder 61. One end of the first guiding cylinder 61 is fixedly inside the limiting ring 11, and a part of the first guiding cylinder 61 is located inside the first spring 21. A first sliding sleeve 631 is arranged in a matching manner on the outside of the first guiding cylinder 61. The first sliding sleeve 631 can move along the first guiding cylinder 61. A first fixing ring 63 is fixedly sleeved on the outside of the first sliding sleeve 631. One end of the first spring 21 away from the first connecting seat 232 is fixedly connected to the first fixing ring 63. The first guiding cylinder 61 cooperates with the first moving sleeve 62. A part of the first moving sleeve 62 is arranged in the first guiding cylinder 61 in a matching manner. One end of the first moving sleeve 62 passes out of the first guiding cylinder 61. A support ring 66 is fixedly sleeved on the end of the first moving sleeve 62 located outside the first guiding cylinder 61. Two first pulleys 64 are arranged at one end of the first guiding cylinder 61 located inside the first spring 21, and the two first pulleys 64 are symmetrically arranged.

[0034] An iron ring 67 is arranged on the support ring 66. An annular electromagnet 68 is arranged on the support seat 1. The annular electromagnet 68 corresponds to the position of the iron ring 67. When the annular electromagnet 68 is energized, it is used to adsorb the iron ring 67. In addition, the first support column 231 passes through the first moving sleeve 62 and the iron ring 67. The inner ring surface diameter of the first moving sleeve 62 is larger than the outer diameter of the first support column 231, and the first support column 231, the first moving sleeve 62, and the first guiding cylinder 61 are coaxial. Therefore, the first support column 231 does not contact the first moving sleeve 62.

[0035] The driving assembly 6 further includes two first connecting ropes 65. One end of each of the two first connecting ropes 65 is fixed to the first fixing ring 63, and the other ends are both fixed to the end of the first moving sleeve 62 away from the support ring 66. And the two first connecting ropes 65 respectively bypass two first pulleys 64. A blocking piece 69 is arranged on the support base 1. The blocking piece 69 is used to block the support ring 66. When the support ring 66 contacts the blocking piece 69 and the first spring 21 is in a normal state, the two first connecting ropes 65 are just in a straightened state or basically tend to be in a straightened state. By energizing the annular electromagnet 68, the iron ring 67 is adsorbed, thereby promoting the horizontal linear movement of the first moving sleeve 62. Under the action of the first connecting rope 65, the first fixing ring 63 can be promoted to move along the first guiding cylinder 61 towards the direction close to the first connecting seat 232, thereby causing the first spring 21 to be compressed, and further causing the first elastic spiral sleeve 22 to be compressed and deformed.

[0036] The second elastic member 3 includes a horizontally arranged second spring 31. A second elastic spiral sleeve 32 is fixedly sleeved on a section of the second spring 31 adjacent to the first elastic member 2. The second elastic spiral sleeve 32 is made of rubber or silica gel. Similarly, for the convenience of the second elastic spiral sleeve 32 to cooperate with the second spring 31, the second elastic spiral sleeve 32 can be arranged in two or more parts, and each part can be spliced by means such as bonding.

[0037] The second support assembly 33 includes a first connecting seat 232. One ends of the second spring 31 and the second elastic spiral sleeve 32 adjacent to the first elastic member 2 are both fixedly connected to the second connecting seat 332. The second support assembly 33 further includes a moving frame 333 and a second support column 331. The second support column 331 is horizontally arranged. One end of the second support column 331 is fixedly connected to the second connecting seat 332, and the other end of the second support column 331 is fixedly arranged on the moving frame 333. The second support column 331 and the first support column 231 are coaxial. The moving frame 333 is used to connect a linear motion mechanism 10, and the linear motion mechanism 10 is used to drive the moving frame 333 to linearly move along the axis direction of the second support column 331. At the same time, the central axis of the second spring 31 is collinear with the axis of the second support column 331.

[0038] The clamping assembly 41 includes a fixed seat 411. The fixed seat 411 is connected to the second lifting assembly 5, and the second lifting assembly 5 is used to drive the fixed seat 411 to move up and down. An arc-shaped clamping plate 412 is fixedly arranged at the bottom of the fixed seat 411. The arc-shaped clamping plate 412 is adapted to the outer wall of the pipe to be cut. That is, by driving the arc-shaped clamping plate 412 to descend through the second lifting assembly 5, the arc-shaped clamping plate 412 can be driven to abut against the outer wall of the pipe. Under the action of the second support and limit seat 9, a fixing effect can be applied to the pipe.

[0039] The transmission component 7 includes a second guiding cylinder 71 arranged horizontally, and a part of the second guiding cylinder 71 is located inside the second spring 31; the second guiding cylinder 71 penetrates through the moving frame 333, and the second guiding cylinder 71 is fixedly connected to the moving frame 333; a second sliding sleeve 731 is arranged in cooperation with the outer part of the second guiding cylinder 71, and the second sliding sleeve 731 can move along the second guiding cylinder 71. A second fixing ring 73 is fixedly sleeved on the outer part of the second sliding sleeve 731, and one end of the second spring 31 far away from the second connecting seat 332 is fixedly connected to the second fixing ring 73; the second guiding cylinder 71 is in cooperation with the second moving sleeve 72, a part of the second moving sleeve 72 is arranged in cooperation inside the second guiding cylinder 71, one end of the second moving sleeve 72 penetrates out of the second guiding cylinder 71, and a fixing block 76 is fixedly sleeved on the end of the second moving sleeve 72 where it penetrates out of the second guiding cylinder 71; two second pulleys 74 are arranged at one end of the second guiding cylinder 71 located inside the second spring 31, and the two second pulleys 74 are symmetrically arranged; two second connecting ropes 75 are fixedly connected to one end of the second moving sleeve 72 far away from the fixing block 76, the other ends of the second connecting ropes 75 are fixedly connected to the second fixing ring 73, and the two second connecting ropes 75 respectively bypass the two second pulleys 74.

[0040] The second support column 331 passes through the second moving sleeve 72. The inner ring surface diameter of the second moving sleeve 72 is larger than the outer diameter of the second support column 331, and the second support column 331, the second moving sleeve 72 and the second guiding cylinder 71 are coaxial.

[0041] The transmission component 7 further includes a third connecting rope 79, a third pulley 77 and a fourth pulley 78 arranged on the moving frame 333. The fourth pulley 78 is located between the third pulley 77 and the fixed seat 411; one end of the third connecting rope 79 is fixedly connected to the fixed seat 411, and the third connecting rope 79 sequentially bypasses the third pulley 77 and the fourth pulley 78.

[0042] In the initial state, the second spring 31 and the second elastic spiral sleeve 32 are in a normal state, and the second connecting rope 75 and the third connecting rope 79 are in a straightened state. And the whole second elastic member 3 is at a proper position relative to the first elastic member 2 (which can be realized by driving the moving frame 333 to move through the linear motion mechanism 10), which can conveniently make one end of the whole pipe material abut against the limiting ring 11 and make the pipe material sleeved on the outer parts of the first spring 21 and the first elastic spiral sleeve 22.

[0043] When placing the pipe, one end of the pipe abuts against the limit ring 11, and the pipe is sleeved outside the first spring 21 and the first elastic spiral sleeve 22. At the same time, the pipe is supported by the first support limit seat 8 and the second support limit seat 9. When the pipe is fitted on the first support limit seat 8 and the second support limit seat 9, the pipe, the first support column 231 and the second support column 331 are coaxial; at this time, the outer walls of the first elastic spiral sleeve 22 and the second elastic spiral sleeve 32 are close to the inner wall of the pipe; then, the linear motion mechanism 10 drives the moving frame 333, etc. to move towards the first elastic member 2 until the second elastic spiral sleeve 32 approaches the first elastic spiral sleeve 22, that is, as Figure 2 shown in the state. At this time, the adjacent ends of the first elastic spiral sleeve 22 and the second elastic spiral sleeve 32 are respectively adjacent to the part of the pipe to be cut. At this time, the cutting disc of the disc cutter 51 corresponds to the area between the first elastic spiral sleeve 22 and the second elastic spiral sleeve 32. Similarly, the cutting disc of the cutter corresponds to the area between the first connecting seat 232 and the second connecting seat 332; then, cooperate with manual temporary pressing to fix the pipe, and drive the fixed seat 411 and the arc-shaped clamping plate 412 to move downward through the first lifting assembly 4. By the arc-shaped clamping plate 412 abutting against and squeezing the outer wall of the pipe, the pipe can be fixed.

[0044] When the arc-shaped clamping plate 412 descends to abut against the pipe, the fixed seat 411 pulls the third connecting rope 79, prompting the fixed block 76 to move away from the second connecting seat 332, further driving the second moving sleeve 72 to move away from the second connecting seat 332. Under the action of the second connecting rope 75 and the second sliding sleeve 731, the second fixed ring 73 can be driven to move towards the second connecting seat 332, causing the second spring 31 to be compressed and deformed, and further causing the second elastic spiral sleeve 32 to be compressed and deformed; that is, during the process of the arc-shaped clamping plate 412 descending and abutting against the pipe, the second elastic spiral sleeve 32 is prompted to be compressed and deformed, and the second elastic spiral sleeve 32 abuts against and squeezes the inner wall of the pipe, which can improve the fixing effect on the pipe.

[0045] After the pipe is abutted by the arc-shaped clamping plate 412, the annular electromagnet 68 is energized, and the annular electromagnet 68 adsorbs the iron ring 67, prompting the first moving sleeve 62 to move horizontally in a straight line. Under the action of the first connecting rope 65, the first fixed ring 63 can be prompted to move along the first guide cylinder 61 towards the first connecting seat 232, causing the first spring 21 to be compressed, and further causing the first elastic spiral sleeve 22 to be compressed and deformed. The first elastic spiral sleeve 22 also abuts against the inner wall of the pipe, which can improve the fixing effect on the pipe; finally, the second lifting assembly 5 drives the disc cutter 51 to descend, and the pipe can be completely cut.

[0046] During the pipe cutting process, since the inner wall of the pipe is abutted and extruded by the first elastic spiral sleeve 22 and the second elastic spiral sleeve 32, the inner wall of the pipe adjacent to the cutting position is extruded, which helps to reduce the concave deformation at the pipe cutting position and improves the cutting quality.

[0047] After cutting is completed, the second lifting assembly 5 drives the disc cutter 51 to reset, and at the same time, the first lifting assembly 4 drives the fixed seat 411 to reset downward, facilitating the reset of the fixing block 76, the second spring 31, the second elastic spiral sleeve 32, etc. At the same time, the annular electromagnet 68 is powered off, facilitating the reset of the iron ring 67, the first spring 21, the first elastic spiral sleeve 22, etc.; by manually pressing the part of the pipe to be cut directly above the second support and limit seat 9 and driving the moving frame 333 to move through the linear motion mechanism 10, the second spring 31, the second elastic spiral sleeve 32, and the second connecting seat 332 can be completely separated from the pipe to be cut; finally, take out a section of the pipe sleeved outside the first elastic member 2, which is the required pipe.
