Description

Technical Field

[0001] The present invention relates to the field of laser cutting technology, and in particular to laser cutting equipment for producing and processing bridge cable troughs. Background Art

[0002] Cable trays are structures used to lay and protect electrical wires and cables. Laser cutting is often used in their processing. Laser cutting achieves high precision, keeping dimensional errors within extremely small limits, ensuring that the specifications of the cable trays meet design requirements and that connections between them are tight and smooth, facilitating smoother cable routing. Laser cutting is suitable for large-scale automated production and can be integrated with automated production lines, enabling efficient and stable cable tray cutting. This reduces manual intervention, improves production quality consistency, and reduces labor intensity and costs. During laser cutting, oxygen reacts with the cutting material, generating significant heat, which helps increase cutting speed and efficiency. Simultaneously, the slag produced by the oxidation reaction is blown away from the cutting area by the oxygen flow, resulting in a smoother cut surface.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: 1. The present invention utilizes a slider and a friction plate to slide at the bottom of the bridge cable duct. When slag is present, the slag makes the bottom of the bridge cable duct uneven. The slag contacts the friction plate, hindering the movement of the friction plate. The friction plate and the slider produce relative displacement, so that the friction plate uses an air pump to pump air into the first telescopic airbag. The first telescopic airbag expands and stretches and uses the tooth plate to drive the flow valve to rotate, increasing the maximum flow rate of the auxiliary gas at the flow valve, thereby avoiding the presence of slag.

[0017] 2. After the first telescopic airbag is fully extended, if there is still slag at the bottom of the cable tray, as the air pump continues to pump air, the air pressure in the first telescopic airbag is too high, and the air pressure pushes the closed baffle to rotate, overcoming the elastic force of the reset coil spring, thereby making the pressure divider tube conductive, so that gas enters the second telescopic airbag and pushes the second wedge to lower the first wedge and the auxiliary soft air pipe, shortening the auxiliary soft air pipe to the cutting seam, thereby increasing the force of the wind on the slag. 3. The present invention lifts the roller and the straight plate through the bridge groove. The thicker the bridge groove, the greater the rotation angle of the synchronization shaft. The first gear, the second gear and the gear ring are used to rotate the knob to adjust the speed at which the ball screw drives the cutting head to slide, that is, to adjust the cutting speed to avoid slag generated by excessive cutting speed.

[0020] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention.

[0022] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0023] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0025] Example 1: This example proposes a laser cutting device for producing and processing bridge ducts, such as Figure 1 As shown, the bottom of the machine tool worktable 1 is fixedly installed with a supporting foot pad 2, the side of the machine tool worktable 1 is slidably connected to the gantry 3, the top of the gantry 3 is slidably connected to the cutting head 4, the inside of the cutting head 4 is slidably connected to the auxiliary soft air pipe 8, and the side of the machine tool worktable 1 is provided with a controller 5 for controlling laser cutting, and the cutting head 4 slides on the top of the gantry 3 through a ball screw commonly used in the prior art.

[0026] like Figure 2 As shown, a slag friction member 6 is provided on the top of the machine tool worktable 1. The slag friction member 6 includes a conveying roller 61. Both ends of the conveying roller 61 are rotatably connected to the machine tool worktable 1. A plurality of conveying rollers 61 are provided, and the conveying rollers 61 are equidistantly distributed in a straight line along the top of the machine tool worktable 1. The top of the conveying roller 61 is in contact with the wire trough. A one-way rotating member is provided at the end of the conveying roller 61, and the bridge wire trough is transported by rotating the conveying roller 61.

[0027] like Figure 3 and Figure 4 As shown, the top of the machine tool worktable 1, located directly below the cutting head 4, is rotatably connected to a guide shaft 67. A one-way rotating member is disposed between a belt 66 and the guide shaft 67. The one-way rotating member comprises a disk 62, fixedly mounted on the end of a conveyor roller 61. The arc surface of the disk 62 is provided with a plurality of annular escape grooves 63 distributed at equal angles. Each escape groove 63 is rotatably connected to a tooth 64. A torsion spring is elastically connected between the rotating shaft of the tooth 64 and the escape groove 63. A ratchet 65, meshing with the tooth 64, is rotatably connected to the top of the machine tool worktable 1. The ratchet 65 is connected to the guide shaft 67 via a belt 66. The ends of the ratchet 65 and the belt 66 are each provided with a pulley connected to the belt 66. A forward and reverse motor, fixedly connected to the ratchet 65, is fixedly mounted inside the machine tool worktable 1. The forward and reverse motor is connected to the guide shaft 67 via a belt 66.

[0028] The ratchet 65 rotates clockwise and drives the teeth 64 to rotate, thereby causing the disc 62 to rotate counterclockwise to transport the bridge cable trough. When the ratchet 65 rotates counterclockwise, the teeth 64 are hooked into the avoidance groove 63, and the ratchet 65 cannot drive the teeth 64 and the disc 62 to rotate, thereby achieving a one-way rotation effect.

[0029] First, the ratchet 65 rotates clockwise and drives the disc 62 and the conveying roller 61 to rotate counterclockwise, moving the bridge wire trough to the bottom of the cutting head 4. Then the ratchet 65 rotates counterclockwise. At this time, due to the unidirectional rotation characteristics of the disc 62, the disc 62 cannot rotate. At this time, the ratchet 65 uses the pulley to drive the belt 66 to move, thereby rotating the guide shaft 67.

[0030] A slider 69 is slidably connected to the middle of the guide shaft 67. A guide groove 68 is formed on the surface of the guide shaft 67. A sliding ball is rotatably connected to the side of the slider 69, and the sliding ball slides in the guide groove 68. The guide groove 68 has a wavy structure. The friction plate 610 has a T-shaped structure. The vertical surface of the friction plate 610 is fixedly connected to the end of the air pump 611. The vertical portion of the friction plate 610 slides on the top of the slider 69. There is a gap between the top of the friction plate 610 and the wire groove.

[0031] During the rotation of the guide shaft 67, the ball on the side of the slider 69 slides along the guide groove 68, so that the slider 69 moves left and right along the cutting seam. When there is slag on the wire groove after laser cutting, the slag is supplemented between the friction plate 610 and the wire groove, so that the friction plate 610 is hindered by the slag when following the movement of the slider 69, so that the friction plate 610 and the slider 69 move relative to each other.

[0032] like Figure 4 and Figure 5As shown, the top of the slider 69 is slidably connected to the air pump 611, the side of the slider 69 is fixedly installed with the air pump 611, the friction plate 610 is fixedly connected to the end of the air pump 611, the top of the cutting head 4 is fixedly installed with a first telescopic air bag 613, a hose 612 is connected between the first telescopic air bag 613 and the air pump 611, the top of the cutting head 4 is fixedly connected to a flow valve 615, the end of the first telescopic air bag 613 is fixedly installed with a tooth plate 614 meshing with the flow valve 615, and there is a gap between the top of the friction plate 610 and the wire groove.

[0033] During the relative movement of the friction plate 610 and the slider 69, the friction plate 610 continuously uses the air pump 611 to inflate the first telescopic airbag 613, thereby extending the first telescopic airbag 613. The end of the first telescopic airbag 613 expands and pushes the gear plate 614, thereby rotating the flow valve 615, and the auxiliary soft air pipe 8 is connected to the flow valve 615.

[0034] In this embodiment, the slider 69 and the friction plate 610 are used to slide at the bottom of the bridge cable trough. When slag is present, the slag makes the bottom of the bridge cable trough uneven, and the slag contacts the friction plate 610, and the movement of the friction plate 610 is hindered. The friction plate 610 and the slider 69 produce relative displacement, so that the friction plate 610 uses the air pump 611 to pump air into the first telescopic airbag 613, and the first telescopic airbag 613 expands and stretches and uses the tooth plate 614 to drive the flow valve 615 to rotate, thereby increasing the maximum flow rate of the auxiliary gas at the flow valve 615, thereby avoiding the presence of slag.

[0035] Example 2: Based on Example 1, this example proposes a laser cutting device for producing and processing bridge cable ducts, such as Figure 6 and Figure 7 As shown, the interior of the cutting head 4 is provided with a wind pressure booster 7, and the wind pressure booster 7 includes a second telescopic airbag 73. The end of the second telescopic airbag 73 is fixedly connected to the cutting head 4, and the other end of the second telescopic airbag 73 is fixedly connected to a second wedge block 72. The second wedge block 72 slides back and forth inside the cutting head 4. The interior of the cutting head 4 is provided with a first wedge block 71, and the first wedge block 71 slides up and down inside the cutting head 4. The auxiliary soft air tube 8 penetrates from the side of the first wedge block 71 and exits from the bottom of the first wedge block 71. A pressure dividing component is provided between the second telescopic airbag 73 and the first telescopic airbag 613.

[0036] The second telescopic airbag 73 is inflated with gas to expand and push the second wedge block 72. The second wedge block 72 squeezes the first wedge block 71, so that the auxiliary soft air pipe 8 moves downward inside the cutting head 4, thereby reducing the distance between the auxiliary soft air pipe 8 and the cutting seam of the bridge cable trough. The distance is reduced to increase the wind pressure and improve the effect of removing slag.

[0037] The pressure-dividing assembly includes a pressure-dividing tube 74, the ends of which are connected to the second telescopic airbag 73 and the first telescopic airbag 613, respectively. A closed baffle 75 is rotatably connected to the interior of the pressure-dividing tube 74, and a return coil spring 76 is elastically connected between the rotating shaft of the closed baffle 75 and the pressure-dividing tube 74. The auxiliary soft air tube 8 is formed into an L-shaped bend, and a relief opening 77 is defined on the side of the cutting head 4, through which the end of the auxiliary soft air tube 8 exits.

[0038] After adjusting the flow rate of the auxiliary gas at the flow valve 615 and the first telescopic airbag 613 is fully extended, if there is still slag at the bottom of the bridge cable duct, the air pressure inside the first telescopic airbag 613 is too high, and the air pressure pushes the closed baffle 75 to rotate, and overcomes the elastic force of the reset coil spring 76, thereby making the pressure dividing tube 74 conductive, and the gas in the first telescopic airbag 613 quickly enters the second telescopic airbag 73, and in order to balance the internal air pressure of the first telescopic airbag 613, the internal gas of the first telescopic airbag 613 enters the second telescopic airbag 73, thereby contracting the first telescopic airbag 613 and reducing the flow rate of the auxiliary gas at the flow valve 615. Subsequently, due to insufficient gas inside the first telescopic airbag 613, the elastic force of the reset coil spring 76 resets the closed baffle 75, thereby closing the pressure dividing tube 74, and repeating the above process, each time the auxiliary soft air tube 8 can move downward a small distance.

[0039] In this embodiment, after the first telescopic airbag 613 is fully extended, if there is still slag at the bottom of the cable tray, as the air pump 611 continues to inflate, the air pressure in the first telescopic airbag 613 is too high, and the air pressure pushes the closed baffle 75 to rotate and overcomes the elastic force of the reset coil spring 76, thereby making the pressure divider tube 74 conductive, so that gas enters the second telescopic airbag 73 and pushes the second wedge block 72 to make the first wedge block 71 and the auxiliary soft air pipe 8 descend, shortening the auxiliary soft air pipe 8 to the position of the cutting seam, and increasing the force of the wind on the slag.

[0040] Example 3: Based on the above example 1 or 2, this example proposes a laser cutting device for producing and processing bridge cable ducts, such as Figure 8 and Figure 9 As shown, a thickness deflector 9 is provided on the top of the machine tool worktable 1, and the thickness deflector 9 includes a support column 91. Two support columns 91 are provided and symmetrically fixedly installed on both sides of the machine tool worktable 1. A synchronization shaft 92 is rotatably connected between the two support columns 91. A connecting rod 93 with an inclined setting is fixedly installed in the middle of the synchronization shaft 92. The end of the connecting rod 93 is hinged with a straight plate 94, and the side of the straight plate 94 is rotatably connected to a roller 95. A gear group is provided on the side of the support column 91 and at the end position of the synchronization shaft 92. The side of the support column 91 is rotatably connected to a knob 99 connected to the gear group.

[0041] The gear set includes a first gear 96, which is fixedly connected to the end of the synchronization shaft 92. The side of the support column 91 is rotatably connected to a second gear 97 that meshes with the first gear 96. The second gear 97 is coaxially connected to a gear ring 98. The end of the knob 99 is provided with teeth, and the gear ring 98 is meshed with the knob 99 through the teeth. The knob 99 is electrically connected to the ball screw, and the bottom of the roller 95 is in contact with the wire groove.

[0042] By moving the bridge wire groove and lifting the roller 95 and the straight plate 94, the connecting rod 93 and the synchronization shaft 92 are rotated, so that the first gear 96 rotates. When the synchronization shaft 92 rotates slightly, the gear ratio of the first gear 96, the second gear 97 and the gear ring 98 is used to increase the rotation angle of the gear ring 98, so that the knob 99 is rotated to adjust the speed at which the ball screw drives the cutting head 4 to slide.

[0043] In this embodiment, the roller 95 and the straight plate 94 are lifted up by the bridge groove. The thicker the bridge groove is, the greater the rotation angle of the synchronization shaft 92 is. The first gear 96, the second gear 97 and the gear ring 98 are used to rotate the knob 99 to adjust the speed at which the ball screw drives the cutting head 4 to slide, that is, to adjust the cutting speed to avoid excessive cutting speed to generate slag.

[0044] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
