Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipe cutting technology, specifically relating to a pipe cutting device with a material separating function. Background Technology
[0002] During pipe cutting, the pipes need to be transported from the raw material rack to a conveyor table for cutting. In related technologies, the equipment for feeding steel pipes can only directly transport the pipes to a predetermined feeding platform, meaning it can only be used to directly feed the conveyor of the cutting equipment. To achieve fixed-distance cutting, a limiting mechanism is needed to cut the pipes into different lengths. While the pipe length measurement time is relatively short, the pipe cutting process is time-consuming, resulting in a waiting time for the length measuring device and a waste of equipment resources. Utility Model Content
[0003] To address the waste of resources caused by the long waiting time of the length measuring device due to the difference between the working time of pipe cutting and the working time of the length measuring device, this utility model provides a pipe cutting device with a material distribution function.
[0004] The embodiments of this utility model are achieved through the following technical solutions:
[0005] A pipe cutting device with a material distribution function includes a length measuring mechanism, a first transfer mechanism, a first cutting mechanism, and at least one set of second cutting mechanisms arranged sequentially. The first transfer mechanism is used to place the pipe on the length measuring mechanism onto the first cutting mechanism. A second transfer mechanism is provided between any second cutting mechanism and the length measuring mechanism. The second transfer mechanism includes a plurality of transfer racks arranged side by side at intervals. The transfer racks are inclinedly provided with cantilever rods. The lower end of the cantilever rod is located on the transfer rack, and the higher end of the cantilever rod is hinged to a receiving arm that can swing upward. A lifting assembly is provided below the length measuring mechanism for driving the pipe through the receiving arm. The lifting assembly and the receiving arm are staggered along the axial direction of the length measuring mechanism. The transfer rack is provided with a lifting assembly for transferring the pipe at the lower end of the cantilever rod to the second cutting mechanism.
[0006] In this design, by setting up a second cutting mechanism and a second transfer mechanism, multiple pipe cutting lines can share a single pipe length measuring mechanism (i.e., the length measuring device mentioned in the background art), thereby enabling multiple pipe cutting lines to cut simultaneously. This achieves the goals of reducing production line investment costs, increasing the utilization rate of the pipe length measuring mechanism (i.e., the length measuring device mentioned in the background art), and improving cutting efficiency.
[0007] In some technical solutions of this utility model, the above-mentioned lifting assembly includes a lifting member that can slide longitudinally on the transfer rack. The upper plane of the lifting member is an inclined plane, and the lower end of the inclined plane bends towards the higher end to form a hook portion, which is located directly above the second cutting mechanism.
[0008] This design cleverly uses a lifting mechanism to move the pipe fittings by leveraging gravity, which saves on power and allows for rapid transfer of the pipe fittings.
[0009] In some technical solutions of this utility model, the aforementioned transfer rack includes a first support rod and a second support rod connected by a crossbeam rod. The end of the cantilever rod away from the receiving arm is connected to the side of the first support rod near the top, and the top of the second support rod is connected to the bottom of the cantilever rod.
[0010] The design of the first and second support rods can provide good support. At the same time, connecting the end of the cantilever rod away from the receiving arm to the side of the first support rod near the top can prevent the pipe from falling directly onto the second cutting mechanism, thus preventing the impact force during its rolling process from damaging the second cutting mechanism.
[0011] In some technical solutions of this utility model, the lifting assembly includes a guide rail disposed on the first support rod and at least two sliders that slide in cooperation with the guide rail. The sliders are disposed on the side of the lifting member. The lifting assembly also includes a power assembly for driving the lifting member to slide back and forth on the guide rail.
[0012] The guide rails and sliders in this design can play a role in guiding motion to a certain extent.
[0013] In some technical solutions of this utility model, a swing groove is provided on the upper side of the end of the cantilever rod near the length measuring mechanism, and a hinge shaft passing through the receiving arm is provided in the swing groove. A torsion spring is sleeved on the hinge shaft between the cantilever rod and the receiving arm.
[0014] This design is simple in structure and can be implemented without an additional power source, which can reduce operating costs to some extent.
[0015] In some technical solutions of this utility model, the above-mentioned lifting assembly includes a lifting and positioning block that can be lifted and lowered on the length measuring mechanism, and the upper surface of the lifting and positioning block has a V-shaped groove.
[0016] The V-groove design reduces the likelihood of the pipes rolling off the lifting positioning block during the lifting process; this design is intended to better stabilize the pipes on the lifting positioning block.
[0017] In some technical solutions of this utility model, the first cutting mechanism and the second cutting mechanism have the same structure, both including a cutting bracket, a first power roller track is installed on the cutting bracket, and a cutting machine is provided at one end of the cutting bracket in the forward direction of the first power roller track.
[0018] Using rollers with V-grooves can prevent pipes from rolling off the first power roller track during the process of being transported to the cutting machine.
[0019] In some technical solutions of this utility model, the length measuring mechanism includes a measuring bracket, a second power roller track is mounted on the measuring bracket, and a length measuring component is provided at one end of the measuring bracket located in the forward direction of the second power roller track.
[0020] In this design, the second power roller track drives the pipe to move and contact the length measuring component to complete the length measurement. This design is more suitable for length measurement in industrial automation control.
[0021] In some technical solutions of this utility model, the first cutting mechanism and the length measuring mechanism are arranged close to each other. The first transfer mechanism includes a plurality of tilting arms with inclined upper planes arranged at intervals. The higher end of the tilting arm extends to the middle of the first power roller track, and the lower side of the higher end of the tilting arm is hinged to the cutting bracket. The lower end of the tilting arm extends to the middle of the second power roller track and bends towards its higher end to form a return bend. A liftable drive rod is provided at the middle position of the bottom of the tilting arm.
[0022] This ingenious design allows for the rapid transfer of the pipe fitting from the length measuring mechanism to the first cutting mechanism, resulting in high efficiency.
[0023] In some technical solutions of this utility model, the measuring bracket is provided with a stop block, which is used to prevent the pipes on the second power roller track from running off the track.
[0024] This design prevents the pipes on the raw material rack from moving off the track due to inertia when they are moved to the length measuring mechanism.
[0025] The technical solution of this utility model has at least the following advantages and beneficial effects: the device is equipped with a length measuring mechanism, a first transfer mechanism, a first cutting mechanism and at least one set of second cutting mechanisms, and the second transfer mechanism is cleverly designed so that multiple cutting lines can cut at the same time, thereby reducing production line input costs, reducing personnel input costs, improving the utilization rate of the pipe length measuring mechanism and improving cutting efficiency.

[0037] Example
[0038] Please refer to Figure 1-5 This embodiment provides a pipe cutting device with a material distribution function, including a length measuring mechanism 2, a first transfer mechanism 3, a first cutting mechanism 4, and at least one set of second cutting mechanisms 5 arranged sequentially. The first transfer mechanism 3 is used to place the pipe on the length measuring mechanism 2 onto the first cutting mechanism 4. A second transfer mechanism 6 is provided between any second cutting mechanism 5 and the length measuring mechanism 2. The second transfer mechanism 6 includes a plurality of transfer racks 7 arranged side by side at intervals. The transfer racks 7 are inclinedly provided with cantilever rods 9. The lower end of the cantilever rods 9 is provided on the transfer racks 7. The higher end of the cantilever rods 9 is hinged to a receiving arm 10 that can swing upward. Below the length measuring mechanism 2, there is a lifting assembly 11 for driving the pipe through the receiving arm 10. The lifting assembly 11 and the receiving arm 10 are staggered along the axial direction of the length measuring mechanism 2. The transfer racks 7 are provided with a lifting assembly 12 for transferring the pipe at the lower end of the cantilever rods 9 to the second cutting mechanism 5.
[0039] The principle of the pipe cutting device: Figure 1 and Figure 5The red lines in the middle represent pipe fittings; the second transfer mechanism 6 also includes a support frame, which has an inclined rod with the same height and inclination as the cantilever rod 9. The support frame is used to assist the cantilever rod 9 in supporting the pipe fittings on the second transfer mechanism 6; the cutting device may also include a raw material rack 1 and a feeder set on the raw material rack 1. The feeder is used to move the pipe fittings on the raw material rack 1 onto the raw material rack 1. The feeder can be a robotic arm. Of course, the feeder in this step can also be replaced by manual labor, that is, the pipe fittings on the raw material rack 1 are placed onto the length measuring mechanism 2 by manual labor. In this embodiment, the feeder is preferred to complete the movement of the pipe fittings from the raw material rack 1 to the length measuring mechanism 2.
[0040] When the pipe reaches the length measuring mechanism 2, after the length measurement is completed, the pipe on the length measuring mechanism 2 can be transferred to the first cutting mechanism 4 through the first transfer mechanism 3 and cut. At this time, the first transfer mechanism 3 is reset, and then the new pipe is placed back on the length measuring mechanism 2 by the feeder from the raw material rack 1. After the measurement is completed, since the time required for length measurement is less than the time required for pipe cutting, the first cutting mechanism 4 is generally still in working state. The pipe on the length measuring device can be transferred to the second cutting mechanism 5 through the second pipe for cutting. The specific transfer process is as follows: First, the lifting assembly 11 below the measuring mechanism is activated, driving the pipe upward. After the pipe rises to a certain position, it collides with the receiving arm 10. Then, the lifting assembly 11 continues to rise, and the pipe presses against the lower surface of the receiving arm 10, causing the receiving arm 10 to be subjected to an upward force and begin to rotate upward. This continues until the receiving arm 10 can completely avoid the upward space of the pipe, at which point the receiving arm stops rotating. At this point, the side of the pipe abuts against the lower surface of the receiving arm 10 in its initial state. The pipe continues to rise under the action of the lifting assembly 11, reaching a certain height (i.e., exceeding the receiving arm 10). After reaching its highest height in the vertical position, the receiving arm 10 separates from the pipe. Because the lifting assembly 11 and the receiving arm 10 are staggered along the axis of the length measuring mechanism 2, there is no movement interference between them. The receiving arm 10 rotates downwards after being unobstructed by the pipe and springs back to its initial position. The lifting assembly 11 then begins to move downwards, and the pipe falls onto the receiving arm 10. Because the cantilever rod 9 is inclined, the pipe rolls under gravity to the bottom end of the cantilever rod 9. Then, the lifting assembly 12 starts, moving the pipe onto the second cutting mechanism 5, completing the transfer. It is worth noting that the number of the second cutting mechanism 5 and the second moving mechanism can be increased in pairs according to the actual working time of the length measuring mechanism 2, the first cutting mechanism 4, and the second cutting mechanism 5.
[0041] In this design, by setting up a second cutting mechanism 5 and a second transfer mechanism 6, multiple pipe cutting lines can share a single pipe length measuring mechanism 2, thereby enabling multiple pipe cutting lines to cut simultaneously. This reduces production line investment costs, increases the utilization rate of the pipe length measuring mechanism 2, and improves cutting efficiency.
[0042] In a preferred embodiment, the lifting assembly 12 includes a lifting member 13 that can slide longitudinally on the transfer rack 7. The upper plane of the lifting member 13 is an inclined plane, and the lower end of the inclined plane bends towards the higher end to form a hook portion 14. The hook portion 14 is located directly above the second cutting mechanism 5.
[0043] In the above embodiment, at the initial position, the highest point of the upper plane of the lifting member 13, i.e., the inclined plane, is located below the lowest point of the upper plane of the cantilever rod 9. During the activation of the second transfer mechanism 6, after reaching the lowest point of the cantilever rod 9 on the transfer rack 7, the lifting member 13 gradually rises, lifting the pipe from the transfer rack 7. When the lifting mechanism rises until the pipe is completely detached from the transfer rack 7, the pipe rolls under gravity to the hook portion 14 of the lifting member 13, i.e., above the second cutting mechanism 5. Then, the lifting mechanism descends, placing the pipe on the second cutting device, which then begins to perform the corresponding process cutting on the pipe. This design cleverly uses the lifting member 13 to move the pipe by gravity, saving power to a certain extent and achieving rapid transfer of the pipe.
[0044] In a preferred embodiment, the transfer rack 7 includes a first support rod 16 and a second support rod 17 connected by a crossbeam 15. The end of the cantilever rod 9 away from the receiving arm 10 is connected to the side of the first support rod 16 near its top, and the top of the second support rod 17 is connected to the bottom of the cantilever rod 9.
[0045] In this embodiment, the distance between the connection point of the cantilever rod 9 to the first support rod 16 and the upper fixed point of the first support rod 16 is preferably greater than the diameter of the pipe. This design can prevent the pipe from being pushed out of the transfer rack 7 during the rolling process of the cantilever rod 9. The design of the first support rod 16 and the second support rod 17 can provide good support. At the same time, connecting the end of the cantilever rod 9 away from the receiving arm 10 to the side of the first support rod 16 near the top can use the first support rod 16 to prevent the pipe from falling directly onto the second cutting mechanism 5, thus preventing the impact force during its rolling process from damaging the second cutting mechanism 5.
[0046] In a preferred embodiment, the lifting assembly 12 includes a guide rail 18 disposed on the first support rod 16 and at least two sliders 19 that slide in cooperation with the guide rail 18. The sliders 19 are disposed on the side of the lifting member 13. The lifting assembly 12 also includes a power assembly 20 for driving the lifting member 13 to slide back and forth on the guide rail 18.
[0047] In the above embodiment, the power component 20 includes a servo motor mounted on the transfer rack 7, the servo motor being connected to a transmission gear, the transmission gear being coupled to a rack, and the rack being connected to the lower end of the lifting component 13; the power component 20 may also be a drive cylinder mounted on the transfer rack 7, with the drive end connected to the lower end of the lifting component 13; when the lifting component 12 needs to move up and down, the power component 20 operates, driving the lifting component 12 to move up and down; the design of the guide rail 18 and the slider 19 in this design can play a certain role in motion guidance.
[0048] In a preferred embodiment, a swing groove 21 is provided on the upper side of the cantilever rod 9 near the length measuring mechanism 2. A hinge shaft 22 passing through the receiving arm 10 is provided in the swing groove 21. A torsion spring 23 located between the cantilever rod 9 and the receiving arm 10 is sleeved on the hinge shaft 22.
[0049] In the above embodiment, in the initial position, the center line of the receiving arm 10 is collinear with the center line of the cantilever rod 9, and the rotation angle of the receiving arm 10 is preferably ninety degrees. The cantilever rod 9 can be made of square steel, and a swing groove 21 is opened on one end of the square steel so that the receiving arm 10, which is hinged to the cantilever rod 9 through the hinge shaft 22, can only rotate upward. The torsion spring 23 allows the receiving arm 10 to return to the initial position when there is no upward force. This design is simple in structure and can be implemented without an additional power source, which can reduce operating costs to a certain extent.
[0050] As a preferred embodiment, the lifting assembly 11 includes a lifting positioning block 24 that is movable and can be lifted on the length measuring mechanism 2, and the upper surface of the lifting positioning block 24 has a V-shaped groove 25.
[0051] In the above embodiment, the length measuring mechanism 2 is provided with a lifting cylinder 39, and the telescopic end of the lifting cylinder 39 is connected to the bottom of the lifting positioning block 24; the design of the V-groove 25 can reduce the rolling of the pipe out of the lifting positioning block 24 during the lifting assembly 11, that is, this design is to better stabilize the pipe on the lifting positioning block 24.
[0052] In a preferred embodiment, the first cutting mechanism 4 and the second cutting mechanism 5 have the same structure, both including a cutting bracket 26, on which a first power roller track 27 is mounted, and a cutting machine 28 is provided at one end of the cutting bracket 26 in the forward direction of the first power roller track 27.
[0053] In the above embodiment, the first powered roller track 27 includes a track frame, on which a unit roller is rotatably mounted. The unit roller is a roller with a V-groove. The first powered roller track 27 uses a motor-driven roller, which is an existing accessory and will not be described in detail here. When the pipe reaches the first powered roller track 27 of the first cutting mechanism 4, it is transported to the cutting machine 28 by the first powered roller track for cutting. The use of a roller with a V-groove can prevent the pipe from rolling out of the first powered roller track 27 during the process of being transported to the cutting machine 28.
[0054] In a preferred embodiment, the length measuring mechanism 2 includes a measuring bracket 29, on which a second power roller track 30 is mounted, and a length measuring component 31 is provided at one end of the measuring bracket 29 in the forward direction of the second power roller track 30.
[0055] In the above embodiment, the second powered roller track 30 and the first powered roller track 27 have the same structure. The length measuring component 31 uses a magnetostrictive displacement sensor (its principle is: the sensor probe is fixed to one side of the pipe, and the magnetic ring (or magnetic target) is installed at the other end of the pipe. The displacement is determined by measuring the change in the magnetic field between the probe and the magnetic ring, and the length is calculated by combining the reference point of the device). In this design, the second powered roller track 30 drives the pipe to move and contact the length measuring component 31 to complete the length measurement. This design is more suitable for length measurement in industrial automation control.
[0056] In a preferred embodiment, the first cutting mechanism 4 and the length measuring mechanism 2 are arranged close to each other. The first transfer mechanism 3 includes a plurality of tilting arms 32 with inclined upper planes arranged at intervals. The higher end of the tilting arm 32 extends to the middle of the first power roller track 27, and the lower side of the higher end of the tilting arm 32 is hinged to the cutting bracket 26. The lower end of the tilting arm 32 extends to the middle position of the second power roller track 30 and bends towards its higher end to form a return bend 33. A liftable drive rod 34 is provided at the middle position of the bottom of the tilting arm 32.
[0057] In the above embodiment, the first transfer mechanism 3 includes a drive shaft 36, and the ends of multiple drive rods 34 away from the turning arm 32 are all sleeved on the drive shaft 36. Multiple power cylinders 37 are sleeved on the drive shaft 36, and the power cylinders 37 are mounted on the measuring bracket 29. The first cutting mechanism 4 and the length measuring mechanism 2 are arranged adjacent to each other, that is, the two mechanisms are arranged close together. This design is beneficial to reducing the transfer distance between the first cutting mechanism 4 and the length measuring mechanism 2, and is also beneficial to reducing the total floor space of the pipe cutting device. The tipping arm 32 is hinged to the cutting bracket 26 adjacent to the first cutting mechanism 4. When it is necessary to transfer the pipe, multiple power cylinders 37 are activated to move upward, driving multiple drive rods 34 upward through the conventional shaft, which in turn drives multiple tipping arms 32 to rotate. During the rotation, the multiple tipping arms 32 lift the pipe on the roller table of the length measuring mechanism 2, that is, lift the pipe on the second power roller track 30. As the tipping arm 32 continues to rotate, the pipe can roll towards the first cutting mechanism 4 under the action of gravity until the pipe rolls onto the roller table of the first cutting feeding device. This design structure is ingenious and can quickly transfer the pipe on the length measuring mechanism 2 to the first cutting mechanism 4 with high efficiency.
[0058] As a preferred embodiment, the measuring bracket 29 is provided with a stop block 35, which is used to prevent the pipes on the second power roller track 30 from going off the track.
[0059] In the above embodiment, the height of the top of the baffle block 35 is greater than the height of the second power roller track 30, and less than the height of the upper plane of the same position of the flipping arm in the flipping state. This can prevent the pipes on the raw material rack 1 from moving out of the track due to the inertia when they are moved into the length measuring mechanism 2.
[0060] In summary, this utility model provides a pipe cutting device with a material distribution function, enabling multiple pipe cutting lines to share a single pipe length measuring mechanism 2, achieving fully automatic machine transfer, and simultaneous cutting by multiple pipe cutting lines. This reduces production line input costs, reduces personnel input costs, increases the utilization rate of the pipe length measuring mechanism 2, and improves cutting efficiency.
