Vertically, the middle part of the lifting arm 85 is hinged to the swing seat 84, and a long strip opening 88 is opened at both ends. Both sides of the upper blocking plate 87 and both sides of the lower blocking plate 86 are provided with linkage columns 89, and each linkage column 89 is movably fitted to the inner wall of one of the long strip openings 88. An integral part 90 is horizontally provided between the bottoms of the two lower blocking plates 86, and a fifth elastic part 91 that is continuously in a compressed state is provided between the top of the supporting base plate 1 and the bottom of the middle part of the integral part 90;

[0113] A one-way seat 92 is provided at the top of the middle portion of the integral member 90. A T-shaped or dovetail-shaped one-way groove 93 is provided on the side of the one-way seat 92 close to the support column 2. A one-way member 94 is movably provided in the one-way groove 93 to cooperate with the one-way groove 93. A one-way column 95 is horizontally provided on the outside of the one-way member 94. A sixth elastic member 96 that is continuously in a compressed state is provided between the top of the one-way member 94 and the top of the one-way groove 93.

[0114] An extension arm 97 is horizontally provided on the side of the horizontal portion 40 located above, and a vertical arm 98 is vertically provided at the free end of the extension arm 97. A retaining plate 99 is horizontally provided on the side of the vertical arm 98 close to the one-way seat 92, and a guide plate 100 is obliquely provided at the upstream end of the retaining plate 99. An adsorption magnet is provided on the downstream side of the pushing portion 43, and a material guide plate 101 is obliquely provided at the upstream end of the support column 2 close to the anti-drop frame 82;

[0115] When the retaining plate 99 and the guide plate 100 are both separated from the one-way column 95, the lower blocking plate 86 contacts the lower side of the lowest steel pipe on the material rail 81, the top of the upper blocking plate 87 is lower than the upper side of the material rail 81, and the linkage column 89 on the lower blocking plate 86 contacts the top of the corresponding long strip opening 88;

[0116] When the upper side of the guide plate 100 acts on the lower side of the one-way column 95, the guide plate 100 drives the one-way column 95 to move upward, and the upper blocking plate 87 and the lower blocking plate 86 remain stationary;

[0117] When the lower side of the guide plate 100 acts on the upper side of the one-way column 95, the guide plate 100 drives the one-way column 95 and the one-way seat 92 to move downward until the top of the one-way column 95 is in contact with the lower side of the retaining plate 99. At this time, the upper blocking plate 87 contacts the lower side of the second steel pipe from the bottom to the top on the material rail 81, and the top of the lower blocking plate 86 is lower than the upper side of the material rail 81.

[0118] When the pushing portion 43 moves to the upstream end, the lowest steel pipe on the material rail 81 hits the steel pipe waste on the adsorption magnet, and hits the steel pipe waste onto the material guide plate 101 .

[0119] The present invention also provides a process for cutting using an automated steel pipe cutting device as described above, comprising the following steps:

[0120] S1, place the steel pipe to be cut between two support columns 2, and move the steel pipe to the desired cutting position;

[0121] S2, the first driving mechanism lowers the height of the lifting frame 4, and the first motor 5 drives the saw blade 6 to rotate;

[0122] S3, the pressing member 12 contacts the top of the steel pipe, and the pressing member 12 and the two support columns 2 fix the position of the steel pipe;

[0123] S4, the lifting frame 4 continues to descend, and the first elastic member 10 is compressed until the saw blade 6 completes cutting the steel pipe;

[0124] S5, the lifting frame 4 is raised until the pressing member 12 is separated from the steel pipe, and the steel pipe is moved downstream by a specified length, and S1-S4 are repeated.

[0125] When cutting a steel pipe, the present invention first places the steel pipe to be cut between the two support columns 2, and moves the steel pipe to the desired cutting position; the first drive mechanism lowers the height of the lifting frame 4, and the first motor 5 drives the saw blade 6 to rotate; the pressing member 12 contacts the top of the steel pipe, and the pressing member 12 and the two support columns 2 fix the position of the steel pipe; the lifting frame 4 continues to descend, and the first elastic member 10 is compressed until the saw blade 6 completes the cutting of the steel pipe; the lifting frame 4 rises until the pressing member 12 separates from the steel pipe, and moves the steel pipe downstream to a specified length, and repeats the above steps until the steel pipe is cut. Since the power source for pressing the steel pipe when cutting the steel pipe is the same as the power source for lifting the saw blade 6, the production and use costs of the equipment are lower, and the mutual coordination between the various units is also simpler, without the need for a special program for control, the use effect is better, and the error rate is lower.

[0126] During actual production, workers will first place a large number of steel pipes on the two material rails 81 awaiting cutting, eliminating the need for workers to constantly wait by the equipment. When cutting the first steel pipe, it is preferred to place the pipe to be cut on the support column 2. At this point, the pusher seat 42 is at the upstream end of its movable range, meaning that the upstream side of the swing plate 65 is in contact with the upstream side of the swing plate 65. The swing plate 65 and the synchronizing plate 63 are not completely rigid, but rather made of a relatively flexible material, such as plastic. This allows the swing plate 65 to have a certain interference fit with the synchronizing plate 63 when in a vertical position. Furthermore, because the swing plate 65 is in a vertical position and its downstream side is in contact with the end stop 66, the fourth elastic member applies an upward tension force. This effectively secures the position of the synchronizing plate 63 as the upper side of the transmission belt 53 moves downstream, ensuring a stable relative position between the synchronizing plate 63 and the transmission belt 53. The bottom of the synchronizing plate 63 is also serrated, meshing with the anti-slip teeth 79 to stably propel the steel pipe downstream. Alternatively, in another embodiment, a deformable resistance-enhancing layer (e.g., rubber, silicone, etc.) is provided on the downstream side of the synchronizing plate 63. This resistance-enhancing layer also allows for a stable connection between the synchronizing plate 63 and the drive belt 53.

[0127] The original length of the steel pipe is set to S1, and the distance between the push part 43 and the end piece 16 is S2. Both S1 and S2 are fixed values ​​(the fixed value can be adjusted according to the actual situation, for example, some steel pipes are 1.5m, some are 2m; but S2 is always fixed), and can be input into the computer. After the steel pipes on the support column 2 are placed, the second motor 19 drives the screw 20 to rotate and raise the lifting frame 4, while also raising the driving frame 44 and the driving column 45. During the raising process of the driving column 45, the driving gear 46 drives the one-way ring 57 to rotate through the passive gear 58 (preferably, the side of the one-way ring 57 has an annular rotating ring, and the longitudinal section of each part of the rotating ring is T-shaped. At the same time, a rotating groove for the rotating ring to be movably engaged is provided on the side of the first support frame 47, so that the one-way ring 57 can rotate with the first support frame 47 while not affecting the passive gear 5 8 and the normal operation of the transmission tooth body 59), at this time the transmission tooth body 59 abuts against the flat part of the one-way body 55 (not the inclined part), so that the one-way ring 57 drives the one-way disk 54 to rotate, and at the same time the first transmission rod 49, the first transmission wheel 51, the second transmission wheel 52 and the transmission belt 53 are all active, and at this time the pushing part 43 is driven downstream to move. When the distance moved by a certain node of the steel pipe reaches S2-S1, the second motor 19 stops (automatically controlled by the controller). At this time, the end of the steel pipe abuts against the terminator 16 to prevent the steel pipe from moving downstream due to inertia.

[0128] Then, both the first motor 5 and the second motor 19 are started, and the second motor 19 lowers the lifting frame 4 via the screw 20. At this point, the one-way ring 57 rotates in the opposite direction, and the transmission gear 59 acts on the outer inclined portion of the one-way body 55 through the inclined surface, driving the one-way body 55 toward the one-way hole until the transmission gear 59 passes over the one-way body 55. There is a certain amount of friction between the first transmission rod 49 and the first support frame 47 (the amount of friction can be selected according to actual conditions). Therefore, when the drive column 45 moves downward, the one-way ring 57 rotates, but the one-way disk 54 remains stationary. Thus, the pusher 43 and the steel pipe remain stationary.

[0129] As the lifting frame 4 descends, the pressing piece 12 is first pressed against the top of the steel pipe; then the lifting frame 4 continues to descend, and after the pressing piece 12 presses the steel pipe tightly enough, the saw blade 6 acts on the top of the steel pipe; as the height of the saw blade 6 further decreases, the pressing piece 12 also presses the steel pipe more stably; at the same time, since a give way groove is opened on the top of the support column 2, both sides of the place where the steel pipe is cut are supported by the support column 2, so that the position of the steel pipe can be better maintained stable, which has the effect of improving the quality of the end of the cut steel pipe.

[0130] Moreover, when the lifting frame 4 is descending, the outer end of the telescopic column 26 will come into contact with the top of the terminating column 15. Since the bottom of the outer end of the telescopic column 26 is inclined, the telescopic column 26 will be retracted toward the telescopic hole 25 until the cutting is completed and the telescopic column 26 moves to the bottom of the terminating column 15. At this time, under the elastic force of the second elastic member 28, the free end of the telescopic column 26 is located below the terminating column 15.

[0131] After a section of the steel pipe is cut (in this embodiment, the steel pipes are preferably cut to a shorter length, such as 20 cm, 35 cm, or other lengths), the lifting frame 4 is raised. During this raising process, the driving column 45, the one-way ring 57, the one-way disc 54, and other structures drive the steel pipe downstream again. The height of the lifting frame 4 at this time may be different from the first raising height, but the height of subsequent raisings for cutting the same steel pipe will be the same. As the lifting frame 4 rises, the telescopic column 26 raises the height of the end piece 16. In this way, the downstream end of the cut steel pipe is not limited by the end piece 16, while the upstream end is pushed by the next steel pipe to be cut. In this way, the steel pipe can be pushed off the support column 2 and dropped down the slide for collection.

[0132] When the lifting frame 4 is raised to a certain height (lower than its maximum height at that time), the unlocking lever 30 contacts the lower side of the unlocking portion 32. Since the unlocking portion 32 is inclined, the unlocking lever 30 moves toward the lifting frame 23, which in turn drives the telescopic column 26 toward the lifting frame 23 until the telescopic column 26 separates from the end column 15. At this time, the end column 15 moves downward under the action of gravity onto the bottom seat 21, and the end column 15 and the end member 16 are restored. The lifting frame 4 then reaches its maximum height, and the end member 16 can now limit the end of the steel pipe, waiting for the next cutting.

[0133] When the lifting frame 4 is just raised, the pushing part 43 pushes the steel pipe downstream. At this time, it is preferred that the bottom or periphery of the clamping piece 12 are provided with balls for reducing resistance; or in another embodiment, the clamping piece 12 is in the shape of an arc with an opening downward, and its inner wall has multiple balls for reducing resistance between it and the steel pipe; or in another embodiment, the clamping piece 12 is in the shape of a roller, but its rotation direction is toward the movement direction of the steel pipe (the accompanying drawings are only for reference and do not represent the actual structure). In this way, the clamping piece 12 can also rotate when the steel pipe moves, thereby reducing the resistance.

[0134] During the cutting process of the steel pipe on the support column 2, the upper side of the guide plate 100 at a certain node will contact the lower side of the one-way column 95 and raise the one-way column 95 and the one-way member 94. At this time, the lower blocking plate 86 and the upper blocking plate 87 both maintain their positions, so the steel pipe on the material rail 81 also maintains a stable position.

[0135] After the last cut of the steel pipe is completed, if the remaining length of the steel pipe is exactly the same as the required length (for example, a 2-meter-long steel pipe is cut into 10 20-cm steel pipe sections, so there is no waste), then during the subsequent raising of the lifting frame 4, the pushing portion 43 can directly push the steel pipe off the support column 2 (due to the large length of the steel pipe, the attraction magnet cannot pull the last section of the steel pipe upstream). However, if there is a piece of waste at the end of the steel pipe after the last cut is completed, the waste can be magnetically attracted by the attraction magnet and subsequently move upstream.

[0136] After the final cut, the synchronous plate 63 continues to move downstream, and at a certain node, the separation rod 70 contacts the lower side of the swing plate 65, causing the swing plate 65 to rotate to an inclined state. At this time, under the tension of the fourth elastic member, the synchronous plate 63 is separated from the transmission belt 53. The presence of the upper limit portion 68 allows the swing plate 65 to remain in an inclined state, facilitating subsequent interaction with the coupling frame 71. After the synchronous plate 63 is separated from the transmission belt 53, the reset block 77 can pull the push seat 42 upstream via the reset cable 78 to move (in this process, the lifting frame 4 does not need to be raised to a large height); preferably, the reset block 77 has a dovetail bar at the bottom and a matching dovetail groove at the top of the reset rail 76. As the reset block 77 moves downward, the bottom of the coupling frame 71 contacts the upstream side of the swing plate 65, driving the swing plate 65 to rotate to a vertical position. This in turn drives the synchronizing plate 63 downward until the swing plate 65 rotates to a vertical position, at which point the synchronizing plate 63 and the bottom plate 61 again clamp the transmission belt 53. Simultaneously, the dovetail strip at the bottom of the reset block 77 also contacts the bottom of the dovetail groove, preventing excessive impact force from being generated between the coupling frame 71 and the swing plate 65.

[0137] During the upstream movement of the push seat 42, the lower side of the guide plate 100 contacts the upper side of the one-way column 95 (preferably rotatably connected to the one-way member 94), driving the one-way column 95, the one-way seat 92, the integral member 90, and the lower blocking plate 86 to move downward, further compressing the fifth elastic member 91. During the downward movement of the lower blocking plate 86, the upper blocking plate 87 is raised by the lifting arm 85. At this time, the upper blocking plate 87 is directly between the first and second steel pipes at the bottom of the material rail 81, and the top of the upper blocking plate 87 is preferably pointed or flat to facilitate insertion between the steel pipes. Before the lower block plate 86 completely disengages from the bottommost steel pipe, the upper block plate 87 rises to a position where it can contact the second steel pipe; then, the one-way column 95 contacts the bottom of the retaining plate 99. At this point, the lower block plate 86 is lower than the top of the material track 81, allowing the bottommost steel pipe to roll down spontaneously, while the second steel pipe is fully blocked by the upper block plate 87 and cannot fall (the upper block plate 87 only needs to play a temporary blocking role). After the retaining plate 99 passes over the one-way column 95, the elastic force of the fifth elastic member 91 causes the lower block plate 86 to rise and the upper block plate 87 to fall. At this time, the lower block plate 86 once again fully limits the position of the steel pipe. Depending on the actual situation, a cylindrical structure can be installed at the bottom of the material track 81 to improve the positional stability and structural strength of the lower and upper block plates 86 and 87.

[0138] The lowermost steel pipe on the material rail 81 pushes the pusher 42 to continue moving downstream, and the inclination of the material rail 81 is small, so the rolling speed of the steel pipe on it is slow, and the pusher 42 moves to the upstream end, and the steel pipe on the material rail 81 rolls onto the support column 2. The steel pipe hits the waste steel pipe on the adsorbing magnet, and the waste steel pipe is separated from the pusher 43, so that the pusher 43 can work normally.

[0139] The feeding of the steel pipe (excluding the placement of the steel pipe on the material rail 81) can be automatically performed, and the forward pushing, discharging, and discharging of the waste and separation of the finished product are all performed automatically, so that the investment and use cost of the equipment is low. At the same time, the anti-falling plate 83 can also limit the position of the steel pipe to prevent the steel pipe from falling off the support column 2.

[0140] The stabilizing part 80 is supported on the upstream side of the driving column 45, which improves the position stability and shape stability of the driving column 45. The reciprocating part 39 and the horizontal part 40 both have the drag-reducing beads 41, so that the activity resistance of the pusher 42 is smaller. At the same time, the position of the termination piece 16 can be adjusted, so that steel pipes with different length requirements can be processed. After adjusting the position of the termination piece 16, the input data also needs to be changed accordingly.

[0141] In another embodiment, the cut steel pipe is directly guided out from the guide plate below the first motor 5, and there is a small horn-shaped distribution hopper on the upstream side of the guide plate, and no adsorbing magnet is needed on the pusher 43; after the last cut is completed, the pusher 43 will continue to move downstream for a certain distance (before the swing plate 65 is unlocked), and during this movement, the waste steel pipe is pushed into the distribution hopper and guided out. The length of the cut steel pipe is too long to fall into the distribution hopper, so the distribution hopper can also realize the classification of finished products and waste.
