Description

Technical Field

[0001] The present invention relates to the technical field of cutting machines, in particular to an automatic laser cutting machine for glass fiber reinforced plastic pipes. Background Art

[0002] FRP pipes, also known as glass fiber wound sand-filled pipes, are mainly reinforced with glass fiber and its products, with high-molecular-weight unsaturated polyester resins, epoxy resins, etc. as basic materials, and inorganic non-metallic granular materials such as quartz sand and calcium carbonate as fillers. During the use of FRP pipes, the FRP pipes need to be cut to the corresponding length by a laser pipe cutting machine to meet the requirements of installation process and space.

[0003] Existing laser tube cutting machines mostly use horizontal tube cutting machines, which cut the FRP tube by circular cutting from the outside to the inside. However, the horizontal laser tube cutting machine occupies a large area and is only suitable for cutting long FRP tubes. In addition, after laser cutting, the particles formed after melting in the FRP tube are difficult to be discharged, and secondary cleaning is often required. In the production process of short tubes, it is often necessary to fix and cut both ends of the glass tube separately. Summary of the Invention

[0011] Preferably, a cleaning mechanism is provided on the machine base and the vertical plate, and the cleaning mechanism includes four first cylinders, two of which are fixedly connected to the upper end of the machine base, and the other two are fixedly connected to the side walls of the vertical plate. The movable ends of the two first cylinders are fixedly connected to the movable plate, the side walls of the movable plate are fixedly connected to the second cylinder, the movable end of the second cylinder is fixedly connected to the fixed column, and the side walls of the fixed column are evenly fixedly connected to a plurality of bristles.

[0013] Preferably, both of the curved plates are provided with a knocking mechanism, and the knocking mechanism includes an L-shaped rod fixedly connected to the outer side wall of the curved plate, the side wall of the L-shaped rod is slidably connected to a sliding rod, the side wall of the sliding rod close to the curved plate is fixedly connected to a knocking head, and the side wall of the sliding rod away from the curved plate is fixedly connected to a first wedge plate, and the side wall of the first wedge plate is elastically connected to the side wall of the L-shaped rod through a plurality of reset springs.

[0014] Preferably, the side wall of the L-shaped rod is rotatably connected to the second gear through a rotating shaft, the side wall of the second gear is fixedly connected to the second wedge plate that cooperates with the first wedge plate, the two L-shaped plates are fixedly connected to the first tooth plate below the mutually adjacent lateral side walls, and the two L-shaped plates are fixedly connected to the second tooth plate below the mutually adjacent vertical side walls.

[0017] Compared with the existing technology, the advantages of the present invention are:

This avoids the problem in the prior art that the granular tumors formed after the FRP tube body is easily left in the FRP tube body after laser cutting and are difficult to be discharged, and often require secondary cleaning.

[0020] 3. At the same time, when cutting the two ends of the FRP pipe body, the FRP pipe body needs to be rotated to a vertical direction. This will facilitate the discharge of the granular nodules and slag inside the FRP pipe body, thereby reducing the residue of granular nodules and slag and other debris in the FRP pipe body.

[0021] 4. A knocking mechanism is provided so that when the two arc-shaped plates move horizontally or vertically, the knocking head intermittently knocks on the FRP pipe body, thereby accelerating the shedding and discharge of the granular tumors in the FRP pipe body.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1 - Figure 9 A glass fiber reinforced plastic pipe automatic laser cutting machine includes a machine base 1, the machine base 1 is provided with a cutting mechanism, the cutting mechanism includes a first laser cutting mechanism 2 fixedly connected to the upper end of the machine base 1, a vertical plate 4 fixedly connected to the lower end of the machine base 1, and a second laser cutting mechanism 3 fixedly connected to the side wall of the vertical plate 4.

[0034] It also includes a lifting and rotating mechanism, which includes two L-shaped plates 5 fixedly connected to the upper end of the base 1, and the corners of the two L-shaped plates 5 are arc-shaped (such as Figure 1As shown), the upper end of the base 1 is fixedly connected to two support plates 38 corresponding to the two L-shaped plates 5, and the upper ends of the two support plates 38 are respectively fixedly connected to the lower ends of the two L-shaped plates 5. The upper end of the base 1 located between the two L-shaped plates 5 is provided with an opening 22.

[0035] It should be noted that the first laser cutting mechanism 2 and the second laser cutting mechanism 3 can automatically laser cut the glass fiber reinforced plastic tube body 6. Automatic laser cutting technology is an existing technology, and the specific structure of the first laser cutting mechanism 2 and the second laser cutting mechanism 3 will not be described in detail here.

[0036] The side walls of the two L-shaped plates 5 that are close to each other are each provided with an L-shaped groove 7, and the inner wall of the L-shaped groove 7 is provided with an L-shaped through hole 8 that is connected to the side wall of the L-shaped plate 5. The inner walls of the two L-shaped through holes 8 are both fitted with a first rod 9, and the inner walls of the two first rods 9 are both slidably connected with a rectangular rod 10. The side walls of the two rectangular rods 10 that are close to each other are both fixedly connected with an arc plate 11, and the side wall of the first rod 9 away from the arc plate 11 is rotatably connected to the first plate 12. The side wall of the first plate 12 away from the L-shaped plate 5 is fixedly connected to the second plate 14 through two electric push rods 13, and the side wall of the second plate 14 is rotatably connected to the second rod 15. The side wall of the rectangular rod 10 away from the arc plate 11 is fixedly connected to one end of the second rod 15, and the upper end of the machine base 1 is rotatably connected to two hydraulic cylinders 28, and the side walls of the movable shafts of the two hydraulic cylinders 28 are respectively rotatably connected to the side walls of the two first plates 12 (such as Figure 1 shown).

[0037] The side wall of the first rod 9 in the L-shaped groove 7 is fixedly connected to the first gear 16, and the arc-shaped tooth plate 17 is fixedly connected to the arc-shaped corner of the L-shaped groove 7. The first gear 16 is engaged with the arc-shaped tooth plate 17 during the movement (as shown in FIG. Figure 5 shown).

[0038] Four card slots 18 are evenly distributed on the side wall of the first rod 9, and four grooves 19 corresponding to the four card slots 18 are opened on the inner wall of the connection between the first plate 12 and the first rod 9. The inner walls of the four grooves 19 are slidably connected to the card plates 20, and the side walls of the four card plates 20 are in contact with the inner walls of the four corresponding card slots 18. The inner wall of the card plate 20 is elastically connected to the inner wall of the groove 19 through a magnetic spring 21.

[0039] It should be noted that after the magnetic spring 21 is energized, due to electromagnetic induction, the magnetic spring 21 interacts with the current in the external magnetic field to generate tensile forces of different sizes to control the tensile deformation and motion state of the magnetic spring 21. When the first gear 16 is not engaged with the arc-shaped tooth plate 17, the power is cut off to the four magnetic springs 21 through the external control mechanism. At this time, the four clamping plates 20 are respectively clamped in the four clamping slots 18 to limit the rotation position of the first rod 9. When the first gear 16 is engaged with the arc-shaped tooth plate 17, the four magnetic springs 21 are energized through the external control mechanism, and the four magnetic springs 21 contract. At this time, the four clamping plates 20 are respectively moved out of the four clamping slots 18, and the rotation position of the first rod 9 is released. At this time, the first rod 9 can rotate.

[0040] When cutting one end of the FRP tube body 6, first place the FRP tube body 6 between the two curved plates 11, then adjust the four electric push rods 13 to contract, drive the two second plates 14 to approach each other, and then drive the two curved plates 11 to approach each other through the two second rods 15 and the two rectangular rods 10, clamping the FRP tube body 6, then adjust the two hydraulic cylinders 28 to extend, drive the two first plates 12 to move horizontally, and drive the FRP tube body 6 to move horizontally through the two first rods 9, the two rectangular rods 10 and the two curved plates 11, so that the FRP tube body 6 moves to the first laser cutting mechanism 2, and cuts the designated position of one end of the FRP tube body 6;

[0041] When it is necessary to cut the other end of the glass fiber reinforced plastic pipe body 6, the two hydraulic cylinders 28 are adjusted to contract. When the two first gears 16 move to engage with the two arc-shaped tooth plates 17 respectively, the external control mechanism energizes the four magnetic springs 21, and then the four magnetic springs 21 contract. At this time, the four card plates 20 are respectively moved out of the four card slots 18, and the rotation position of the first rod 9 is loosened. Subsequently, the two first gears 16 drive the two first rods 9 to rotate ninety degrees under the action of the two arc-shaped tooth plates 17, and then drive the glass fiber reinforced plastic pipe body 6 to rotate ninety degrees through the two rectangular rods 10 and the two arc-shaped plates 11. The steel pipe body 6 rotates 90 degrees so that the uncut end of the FRP pipe body 6 is located at the bottom. Then, the two hydraulic cylinders 28 are adjusted to contract so that the two first gears 16 are separated from the two arc-shaped tooth plates 17 respectively. At this time, the external control mechanism cuts off the power to the four magnetic springs 21. At this time, the four clamping plates 20 are respectively clamped in the four clamping grooves 18 to limit the rotation position of the first rod 9. Then, the FRP pipe body 6 continues to move downward so that the FRP pipe body 6 passes through the opening 22 and enters the second laser cutting mechanism 3, and the designated position of the other end of the FRP pipe body 6 is cut;

[0042] In this way, after the FRP tube body 6 is clamped once, both ends of the FRP tube body 6 can be laser cut, effectively utilizing the vertical space of the equipment, avoiding the use of horizontal tube cutting machines in the existing technology, which results in a large equipment footprint, and in the production process of short tubes, it is often necessary to fix and cut the two ends of the glass tube separately.

[0043] A cleaning mechanism is provided on the machine base 1 and the vertical plate 4, and the cleaning mechanism includes four first cylinders 23, two of which are fixedly connected to the upper end of the machine base 1, and the other two first cylinders 23 are fixedly connected to the side walls of the vertical plate 4. The movable ends of the two first cylinders 23 are fixedly connected to the movable plate 24, and the side wall of the movable plate 24 is fixedly connected to the second cylinder 25, and the movable end of the second cylinder 25 is fixedly connected to the fixed column 26, and the side wall of the fixed column 26 is evenly fixedly connected with a plurality of bristles 27.

[0044] It also includes a glass fiber reinforced plastic pipe body 6, the inner side wall of the arc plate 11 is fitted with the outer side wall of the glass fiber reinforced plastic pipe body 6 (such as Figure 3 As shown), the central axis of the fixed column 26 located above the machine base 1 is consistent with the central axis of the glass fiber reinforced plastic pipe body 6 when it is placed horizontally, and the central axis of the fixed column 26 located below the machine base 1 is consistent with the central axis of the glass fiber reinforced plastic pipe body 6 when it is placed vertically.

[0045] After cutting one end of the FRP tube body 6, the two first cylinders 23 at the cutting position of the FRP tube body 6 can be adjusted to extend so that the central axis of the fixed column 26 there is consistent with the central axis of the cut end of the FRP tube body 6. Then, the two second cylinders 25 are adjusted to extend to drive the fixed column 26 and multiple bristles 27 into the FRP tube body 6 to clean the possible granular tumors in the FRP tube body 6, avoiding the problem in the prior art that the granular tumors formed after the FRP tube body 6 is easily left in the FRP tube after laser cutting and are difficult to be discharged, and secondary cleaning is often required.

[0046] At the same time, when cutting the two ends of the FRP pipe body 6, the FRP pipe body 6 needs to be rotated to a vertical direction, which facilitates the discharge of the granular nodules and slag inside the FRP pipe body 6 to reduce the residue of granular nodules and slag and other debris in the FRP pipe body 6.

[0047] The two arc-shaped plates 11 are provided with a knocking mechanism, which includes an L-shaped rod 29 (such as Figure 8 As shown), the side wall of the L-shaped rod 29 is slidably connected to a sliding rod 30, the side wall of the sliding rod 30 close to the arc plate 11 is fixedly connected to a striking head 31, and the side wall of the sliding rod 30 away from the arc plate 11 is fixedly connected to a first wedge plate 32, and the side wall of the first wedge plate 32 is elastically connected to the side wall of the L-shaped rod 29 through multiple return springs 33.

[0048] The side wall of the L-shaped rod 29 is rotatably connected to the second gear 34 through a rotating shaft. The side wall of the second gear 34 is fixedly connected to a second wedge plate 36 that cooperates with the first wedge plate 32. The lower sides of the two L-shaped plates 5 that are close to each other are fixedly connected to a first tooth plate 35. The lower sides of the two L-shaped plates 5 that are close to each other are fixedly connected to a second tooth plate 37 (as shown in FIG. Figure 4 and Figure 7 shown).

[0049] The first wedge plate 32 and the second wedge plate 36 are both arc-shaped (eg Figure 9 shown).

[0050] When the two arc-shaped plates 11 move laterally, the two second gears 34 rotate under the action of the two first toothed plates 35. The rotation of the second gears 34 causes the second wedge plate 36 to intermittently squeeze the first wedge plate 32. At this time, the first wedge plate 32 moves back and forth under the elastic force of the multiple return springs 33 and the pressure of the second wedge plate 36. The sliding rod 30 drives the knocking head 31 to move back and forth, so that the knocking head 31 intermittently knocks the FRP pipe body 6, thereby accelerating the shedding of the granular tumors in the FRP pipe body 6.

[0051] When the two arc-shaped plates 11 move vertically, the two second gears 34 rotate under the action of the two second tooth plates 37. The rotation of the second gear 34 causes the second wedge plate 36 to intermittently squeeze the first wedge plate 32. At this time, the first wedge plate 32 moves back and forth under the elastic force of multiple return springs 33 and the pressure of the second wedge plate 36. The sliding rod 30 drives the knocking head 31 to move back and forth, so that the knocking head 31 intermittently knocks the glass fiber reinforced plastic pipe body 6, thereby accelerating the shedding and discharge of the granular tumor in the glass fiber reinforced plastic pipe body 6.

[0052] When laser cutting the FRP tube body 6, first, the FRP tube body 6 is placed between the two curved plates 11, and then the four electric push rods 13 are adjusted to retract, driving the two second plates 14 to approach each other, and then the two second rods 15 and the two rectangular rods 10 drive the two curved plates 11 to approach each other, clamping the FRP tube body 6, and then adjusting the two hydraulic cylinders 28 to extend, driving the two first plates 12 to move horizontally, and driving the FRP tube body 6 to move horizontally through the two first rods 9, the two rectangular rods 10 and the two curved plates 11, so that the FRP tube body 6 moves to the first laser cutting mechanism 2, and cuts the designated position of one end of the FRP tube body 6. After the cutting is completed, the two first cylinders 23 at the cutting position of the FRP tube body 6 are adjusted to extend so that the central axis of the fixed column 26 there is consistent with the central axis of the cutting end of the FRP tube body 6, and then adjusting the two second cylinders 25 to extend, driving the fixed column 26 and a plurality of brushes 27 to enter the FRP tube body 6 to clean the granular tumors that may exist in the FRP tube body 6;

[0053] When it is necessary to cut the other end of the FRP tube body 6, the two hydraulic cylinders 28 are adjusted to contract. When the two first gears 16 move to engage with the two arc-shaped tooth plates 17 respectively, the external control mechanism energizes the four magnetic springs 21, and then the four magnetic springs 21 contract. At this time, the four clamping plates 20 are respectively moved out of the four clamping slots 18, and the rotation position of the first rod 9 is loosened. Subsequently, the two first gears 16 drive the two first rods 9 to rotate ninety degrees under the action of the two arc-shaped tooth plates 17, and then drive the FRP tube body 6 to rotate ninety degrees through the two rectangular rods 10 and the two arc-shaped plates 11, so that the uncut end of the FRP tube body 6 is located at the bottom, and then continue to adjust the two hydraulic cylinders 28 to contract, so that the two first gears 16 are respectively moved out of the four clamping slots 18, and the rotation position of the first rod 9 is loosened. The first rod 9 is not separated from the two arc-shaped tooth plates 17. At this time, the external control mechanism cuts off the power to the four magnetic springs 21. At this time, the four card plates 20 are respectively clamped in the four card slots 18 to limit the rotation position of the first rod 9. Then the FRP tube body 6 continues to move downward, so that the FRP tube body 6 passes through the opening 22 to the second laser cutting mechanism 3, and the designated position of the other end of the FRP tube body 6 is cut. Then, the two first cylinders 23 at the cutting position of the FRP tube body 6 are adjusted to extend so that the central axis of the fixed column 26 there is consistent with the central axis of the cutting end of the FRP tube body 6. Then, the two second cylinders 25 are adjusted to extend, driving the fixed column 26 and multiple bristles 27 to enter the FRP tube body 6 to clean the granular tumors that may exist in the FRP tube body 6.

[0054] When the FRP pipe body 6 is rotated to a vertical direction, the granular slag inside the FRP pipe body 6 is easily discharged to reduce the amount of debris such as granular slag remaining in the FRP pipe body 6;

[0055] When the two arc-shaped plates 11 move laterally, the two second gears 34 rotate under the action of the two first toothed plates 35. The rotation of the second gears 34 causes the second wedge plate 36 to intermittently squeeze the first wedge plate 32. At this time, the first wedge plate 32 moves back and forth under the elastic force of the multiple return springs 33 and the pressure of the second wedge plate 36. The sliding rod 30 drives the knocking head 31 to move back and forth, so that the knocking head 31 intermittently knocks the FRP pipe body 6, thereby accelerating the shedding of the granular tumors in the FRP pipe body 6.

[0056] When the two arc-shaped plates 11 move vertically, the two second gears 34 rotate under the action of the two second tooth plates 37. The rotation of the second gear 34 causes the second wedge plate 36 to intermittently squeeze the first wedge plate 32. At this time, the first wedge plate 32 moves back and forth under the elastic force of multiple return springs 33 and the pressure of the second wedge plate 36. The sliding rod 30 drives the knocking head 31 to move back and forth, so that the knocking head 31 intermittently knocks the glass fiber reinforced plastic pipe body 6, thereby accelerating the shedding and discharge of the granular tumor in the glass fiber reinforced plastic pipe body 6.

[0057] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
