Description

Technical Field

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

[0002] FRP pipe, also known as glass fiber wound sand-filled pipe, mainly uses glass fiber and its products as reinforcing materials, unsaturated polyester resin, epoxy resin and other high molecular weight components as basic materials, and inorganic non-metallic granular materials such as quartz sand and calcium carbonate as fillers as the main raw materials. During the use of FRP pipe, it is necessary to cut the FRP pipe to the corresponding length through a laser pipe cutting machine to meet the requirements of installation process and space.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0022] Reference Figure 1 - Fig. 9 An automatic laser cutting machine for a glass fiber reinforced plastic pipe comprises a machine base 1, the machine base 1 is provided with a cutting mechanism, the cutting mechanism comprises 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.

[0023] 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 both arc-shaped (such as Figure 1 As shown), two support plates 38 corresponding to the two L-shaped plates 5 are fixedly connected to the upper end of the base 1, and the upper ends of the two support plates 38 are fixedly connected to the lower ends of the two L-shaped plates 5 respectively. An opening 22 is opened at the upper end of the base 1 located between the two L-shaped plates 5.

[0024] It should be noted that the first laser cutting mechanism 2 and the second laser cutting mechanism 3 can perform automatic laser cutting on the FRP tube body 6, as automatic laser cutting technology is an existing technology, and thus the specific structures of the first laser cutting mechanism 2 and the second laser cutting mechanism 3 are not described in detail here.

[0025] The side walls of the two L-shaped plates 5 close to each other are provided with L-shaped grooves 7, and the inner walls of the L-shaped grooves 7 are provided with L-shaped through holes 8 connected to the side walls of the L-shaped plates 5. The inner walls of the two L-shaped through holes 8 are fitted with first rods 9, and the inner walls of the two first rods 9 are slidably connected with rectangular rods 10, and the side walls of the two rectangular rods 10 close to each other are fixedly connected with arc plates 11, and the side walls of the first rod 9 away from the arc plates 11 are rotatably connected with the first plate 12, and the side walls of the first plate 12 away from the L-shaped plate 5 are fixedly connected with the second plate 14 through two electric push rods 13, and the side walls of the second plate 14 are rotatably connected with the second rod 15, and the side walls of the rectangular rod 10 away from the arc plates 11 are 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 rotatably connected to the side walls of the two first plates 12 respectively (such as Figure 1 as shown).

[0026] The side wall of the first rod 9 located in the L-shaped groove 7 is fixedly connected to the first gear 16, and the arc-shaped corner of the L-shaped groove 7 is fixedly connected to the arc-shaped toothed plate 17. The first gear 16 is meshed with the arc-shaped toothed plate 17 during the movement (such as Figure 5 as shown).

[0027] 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 with 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.

[0028] 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 pulling forces of different sizes to control the tensile deformation and movement state of the magnetic spring 21. When the first gear 16 is not engaged with the arc-shaped tooth plate 17, the four magnetic springs 21 are powered off by the external control mechanism. 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. When the first gear 16 is engaged with the arc-shaped tooth plate 17, the four magnetic springs 21 are powered on by 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 grooves 18 to release the rotation position of the first rod 9, and the first rod 9 can rotate.

[0029] When cutting one end of the FRP tube body 6, first place the FRP tube body 6 between the two arc 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 arc plates 11 to approach each other through the two second rods 15 and the two rectangular rods 10, clamp 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 arc 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; 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 released. 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, and 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 to the second laser cutting mechanism 3, and the designated position of the other end of the FRP pipe body 6 is cut; In this way, after a single clamping of the FRP tube body 6, both ends of the FRP tube body 6 can be laser cut, effectively utilizing the vertical space of the equipment and avoiding the use of horizontal tube cutting machines in the prior art, which results in a large footprint of the equipment. In addition, during the production of short tubes, it is often necessary to perform fixed cutting on both ends of the glass tube separately.

[0030] 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 a movable plate 24, the side wall of the movable plate 24 is fixedly connected to a second cylinder 25, the movable end of the second cylinder 25 is fixedly connected to a fixed column 26, and the side wall of the fixed column 26 is evenly fixedly connected with a plurality of bristles 27.

[0031] It also includes a glass fiber reinforced plastic pipe body 6, the inner side wall of the arc plate 11 is in contact with the outer side wall of the glass fiber reinforced plastic pipe body 6 (such as Figure 3As 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.

[0032] 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 granular tumors that may exist in the FRP tube body 6, thereby 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.

[0033] 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 is convenient for discharging 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.

[0034] 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 a plurality of return springs 33.

[0035] The side wall of the L-shaped rod 29 is rotatably connected to the second gear 34 through a rotating shaft, and the side wall of the second gear 34 is fixedly connected to the second wedge plate 36 that cooperates with the first wedge plate 32. The lower parts of the lateral side walls of the two L-shaped plates 5 that are close to each other are fixedly connected to the first toothed plate 35, and the lower parts of the vertical side walls of the two L-shaped plates 5 that are close to each other are fixedly connected to the second toothed plate 37 (such as Figure 4 and Figure 7 as shown).

[0036] The first wedge plate 32 and the second wedge plate 36 are both in an arc shape (eg Fig. 9 as shown).

[0037] When the two arc-shaped plates 11 move laterally, the two second gears 34 rotate under the action of the two first tooth 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 knocking head 31 is driven to move back and forth through the sliding rod 30, so that the knocking head 31 intermittently knocks the FRP pipe body 6, thereby accelerating the shedding of the granular tumor in the FRP pipe body 6. When the two arc 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 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 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 on the FRP pipe body 6, thereby accelerating the shedding and discharge of the granular tumor in the FRP pipe body 6.

[0038] When laser cutting the FRP tube body 6, firstly, the FRP tube body 6 is placed between the two arc plates 11, then the four electric push rods 13 are adjusted to contract, and the two second plates 14 are driven to approach each other, and then the two arc plates 11 are driven to approach each other through the two second rods 15 and the two rectangular rods 10, and the FRP tube body 6 is clamped, and then the two hydraulic cylinders 28 are adjusted to extend, and the two first plates 12 are driven to move horizontally, and the FRP tube body 6 is driven to move horizontally through the two first rods 9, the two rectangular rods 10 and the two arc plates 11, so that the FRP tube body 6 moves to the first laser cutting mechanism 2, and the designated position of one end of the FRP tube body 6 is cut. 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 at the position is consistent with the central axis of the cutting end of the FRP tube body 6, and then the two second cylinders 25 are adjusted to extend, and the fixed column 26 and a plurality of bristles 27 are driven to enter the FRP tube body 6, and the granular tumors that may exist in the FRP tube body 6 are cleaned; 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 toothed 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 released. Subsequently, the two first gears 16 drive the two first rods 9 to rotate ninety degrees under the action of the two arc-shaped toothed 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 the two hydraulic cylinders 28 are adjusted to contract, so that the two first gears 16 are respectively moved out of the four card slots 18, and the rotation position of the first rod 9 is released. The first rod 9 is 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 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 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 at this position 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 a plurality of bristles 27 to enter the FRP tube body 6 to clean the granular tumors that may exist in the FRP tube body 6. 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 residue of granular slag and other debris in the FRP pipe body 6; When the two arc-shaped plates 11 move laterally, the two second gears 34 rotate under the action of the two first tooth 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 knocking head 31 is driven to move back and forth through the sliding rod 30, so that the knocking head 31 intermittently knocks the FRP pipe body 6, thereby accelerating the shedding of the granular tumor in the FRP pipe body 6. When the two arc 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 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 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 on the FRP pipe body 6, thereby accelerating the shedding and discharge of the granular tumor in the FRP pipe body 6.
