Description

Technical Field

[0001] This invention relates to the field of laser cutting machinery technology, specifically to a laser cutting machine for sleeve cutting based on a disc buckle upright. Background Technology

[0002] Disc-lock upright sleeves are important connecting components in disc-lock scaffolding systems. The flatness of their cut ends, dimensional accuracy, and port cleanliness directly affect the assembly accuracy and overall structural stability of the scaffolding. Currently, the industry generally uses traditional laser cutting machines for fixed-length cutting of disc-lock sleeves, which still has many technical defects in actual production.

[0003] Firstly, traditional laser cutting machines mostly adopt an open cutting structure when performing sleeve cutting operations. During the cutting process, the high temperature of the laser melting metal will generate a large amount of metal fumes, ultrafine metal dust, and oil fumes formed by the high temperature volatilization of anti-rust oil from the pipe. These fumes are very easy to spread everywhere, which not only pollutes the workshop working environment and endangers the health of operators, but also easily adheres to the surface of precision components such as laser cutting lenses and guide rails, causing lens contamination, optical path misalignment, and equipment dust accumulation and jamming. This significantly reduces cutting accuracy and equipment lifespan, resulting in high equipment maintenance frequency and high operation and maintenance costs.

[0004] Secondly, traditional sleeve cutting equipment lacks a dedicated port purification structure. After the sleeve is cut, fine dust and oxidized debris are easily left at both ends of the cut port, resulting in poor cleanliness of the sleeve port and affecting the accuracy of subsequent welding and assembly. To address this, the present invention proposes a laser cutting machine for sleeve cutting based on disc buckle uprights to solve the above-mentioned defects. Summary of the Invention

[0005] The purpose of this invention is to provide a laser cutting machine for sleeve cutting based on a disc buckle upright, so as to solve the problems mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: including a machine body assembly, a cutting processing assembly, and an end processing assembly;

[0006] The machine body assembly includes a chassis, and a feed drive mechanism is provided on the side of the chassis;

[0007] Gear 1 and Gear 2 are rotatably mounted in the upper and lower parts of the chassis, respectively. Gear 1 and Gear 2 mesh with each other, and rollers are fixedly connected to the sides of both gears.

[0008] Feeding holes are provided through both sides of the chassis, and a triangular claw disk that is rotatably connected to the chassis is provided on the side of one of the feeding holes.

[0009] A laser cutting head is provided above the triangular claw disk, and side arms are symmetrically installed on both sides of the outer wall of the laser cutting head.

[0010] The cutting assembly includes a boom mounted on the outer wall of the machine body. A slide is fixedly connected to the bottom of the boom, and a mounting bracket is slidably mounted on the slide. A support bar is fixedly connected to the bottom of the mounting bracket. The support bar passes through the machine housing and is slidably connected to it. Two sets of spring rods are respectively mounted on the support bar. A rack is slidably mounted on the spring rod. The bottom of the rack abuts against the spring on the spring rod. The output shaft of a hydraulic cylinder is connected to the bottom of the rack. The hydraulic cylinder is fixedly mounted on the support bar. The rack is movably engaged with a gear.

[0011] Preferably, the mounting bracket is elastically connected to the slide, and protective covers are symmetrically and slidably arranged on both sides of the mounting bracket. The top of the protective cover abuts against an elastic element that is movably sleeved in the middle of the mounting bracket.

[0012] Preferably, the protective cover is composed of two semi-cylindrical sections joined together. A notch is provided through the side of the protective cover near the triangular claw disk. The notch is adapted to the diameter of the cylindrical section. A sputtering cavity is provided inside the protective cover near the notch. A cutting through opening is provided at the top of the protective cover. The cutting through opening is connected to the interior of the sputtering cavity.

[0013] Preferably, a guide frame is fixedly installed on the top of the protective cover. The guide frame is inclined and its surface abuts against the side arm.

[0014] Preferably, a shrink box is provided inside the protective cover near the sputtering cavity. The shrink box has a larger space on the side near the sputtering cavity and a smaller space on the side away from the sputtering cavity. Several air holes are opened through the shrink box on the side near the sputtering cavity. A vacuum cleaner is connected to the side of the shrink box away from the sputtering cavity.

[0015] Preferably, the port processing component includes a ramp frame disposed below the slide, the ramp frame being inclined downward along the cut of the chassis, and a transmission mechanism disposed below the ramp frame, the transmission mechanism being connected to a carrying seat through the ramp frame.

[0016] Preferably, the carrying seat has two air holes on both sides in the horizontal direction, and the air holes are connected to the vacuuming device through a conduit.

[0017] Preferably, the carrying seat is hinged to a baffle on the side facing the bottom of the ramp, and a torsion spring is connected between the side of the baffle and the carrying seat. A limit arm is fixedly connected to the bottom of the ramp, and the limit arm abuts against the upper part of the baffle.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] In this invention, a laser cutting head linkage adaptive closed protection is achieved, which has good protection effect and high degree of automation. During the downward movement of the laser cutting head, the side arm and the inclined guide frame abut against each other, automatically pushing the two sets of semi-cylindrical protective covers to close. After the cutting is completed, they automatically open as the cutting head is raised, without the need for additional independent drive control. The structure has strong linkage and fast response speed. During the cutting process, the protective cover completely covers the sleeve cutting area and forms a closed space with the internal sputtering cavity, while avoiding large-scale leakage of smoke and dust.

[0020] In this invention, a shrink box structure with a large air inlet and a small air outlet is set inside the protective cover. Combined with evenly arranged air holes, it forms a negative pressure adsorption effect, which can concentrate and efficiently collect metal fumes, ultrafine dust, and high-temperature oil fumes in the sputtering cavity at the moment of cutting. This inhibits the spread of pollutants from the source, effectively protects the laser lens and the precision structure of the equipment, reduces the equipment failure rate and maintenance costs, and improves the workshop working environment.

[0021] In this invention, based on the primary dust removal at the cutting source, a port treatment component is added. Through the air holes on both sides of the carrier, the cutting ports at both ends of the sleeve are subjected to secondary negative pressure dust suction, which deeply removes residual fine dust, oxide debris and burr impurities from the ports, greatly improving the cleanliness of the sleeve ports, ensuring the quality of subsequent assembly and welding, and solving the technical pain points of dirt and residual impurities at traditional cutting ports.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 8 This embodiment provides a laser cutting machine for sleeve cutting based on disc buckle uprights, which is specially used for fixed-length cutting of standard carbon steel sleeves. The whole machine consists of three main parts: machine body assembly 100, cutting processing assembly 200, and end processing assembly 300.

[0036] The machine body assembly 100 includes a housing 101. A feed drive mechanism 102 is mounted on the side of the housing 101 to realize continuous horizontal feeding of the sleeve tube. Inside the housing 101, gear 103 and gear 2 104 are rotatably installed on the top and bottom respectively. Rollers 105 are fixed on the sides of both gears. The tube is driven to rotate by friction. Feed holes 106 are opened on the left and right sides of the housing 101. A triangular claw disk 107 is rotatably installed next to one of the feed holes 106 to center and clamp the end of the sleeve. A laser cutting head 108 is arranged above the triangular claw disk 107. Two sets of side arms 109 are symmetrically fixed on the outer wall of the laser cutting head 108.

[0037] The cutting assembly 200 includes a boom 201 fixed to the outer wall of the chassis. The bottom end of the boom 201 is connected to a slide 202. A mounting bracket 203 is slidably mounted on the slide 202. A support bar 204 is fixed to the bottom of the mounting bracket 203. The support bar 204 passes through the chassis 101 and can slide relative to it. Two sets of spring rods 205 are provided on the support bar 204. A rack 206 is slidably sleeved on the outer side of the spring rods 205. The bottom of the rack 206 abuts against the springs of the spring rods 205. The lower end of the rack 206 is connected to the output shaft of a hydraulic cylinder 207. The hydraulic cylinder 207 is fixed to the support bar 204. The rack 206 can achieve controllable meshing transmission with a gear 103. The mounting bracket 203 has symmetrically sliding supports on both sides. A semi-cylindrical protective cover 208 is placed, and an elastic element 209 is movably fitted in the middle of the mounting bracket 203. The bottom end of the elastic element 209 abuts against the top of the protective cover 208. A notch 210 adapted to the outer diameter of the cylindrical part is opened on one side of the protective cover 208, forming a sputtering cavity 211 inside. A cutting through 212 communicating with the sputtering cavity 211 is opened on the top. An inclined guide frame 213 is fixed on the top of the protective cover 208. The guide frame 213 cooperates with the side arm 109 of the laser cutting head. A tapered shrink box 214 is installed inside the protective cover 208 near the sputtering cavity 211. The large diameter end of the shrink box 214 faces the sputtering cavity 211 and has several air holes 215. A vacuum cleaner 216 is connected to the small diameter end.

[0038] The port processing component 300 includes a ramp 301 fixed below the slide 202. The ramp 301 is arranged obliquely downward from the cutting position. A transmission mechanism 302 is installed below the ramp 301. The transmission mechanism 302 passes through the ramp 301 upward and is connected to the carrying seat 303. Air holes 304 are opened on both horizontal sides of the carrying seat 303. A dust collection device is connected to the external air holes 304. A baffle 305 is hinged to the discharge side of the carrying seat 303. A torsion spring 306 is connected between the baffle 305 and the carrying seat 303. A limiting arm 307 is fixed at the bottom of the ramp 301. The limiting arm 307 abuts against the upper part of the baffle 305.

[0039] The actual operation process of this embodiment is as follows:

[0040] In the initial state of the equipment, the hydraulic cylinder 207, the vacuum cleaner 216, and the transmission mechanism 302 are all in the reset state, and the two sets of protective covers 208 remain open. The entire sleeve tube is inserted through the feeding holes 106 on both sides of the machine box 101. The feed drive mechanism 102 is started to transport the tube until the preset cutting position is aligned with the laser cutting head 108. Then, the triangular claw disk 107 clamps the end of the tube to complete the centering and prevent the tube from eccentrically shaking during the cutting process. Simultaneously, the hydraulic cylinder 207 is started to push the rack 206 to mesh with the first gear 103. The first gear 103, the second gear 104, and the roller 105 rotate to drive the tube to rotate at a uniform speed. At the same time, the rack 206 moves the mounting bracket 203 toward the tube side, so that the protective cover 208 reaches the working position.

[0041] The laser cutting head 108 moves downward, and its two side arms 109 contact the inclined guide frame 213, which pushes the two sets of protective covers 208 to close together and surround the outside of the sleeve. The end of the laser cutting head 108 passes through the cutting opening 212 and enters the sputtering cavity 211. The laser generator is started and works with the rotation of the pipe to complete the ring cutting operation. The vacuum cleaner 216 is turned on throughout the operation. The metal slag, dust and oil fumes in the sputtering cavity 211 enter the shrink box 214 through the air hole 215. The shrinking structure forms a negative pressure airflow to collect them, effectively preventing the pollutants from overflowing.

[0042] After the sleeve is cut, the laser cutting head 108 moves upward and resets, the side arm 109 disengages from the guide frame 213, the protective cover 208 reopens under the action of the elastic element 209, the hydraulic cylinder 207 retracts, the rack 206 disengages from the gear 103, all transmission components stop operating, the cut sleeve slides down the ramp 301 onto the carrier 303, the transmission mechanism 302 drives the carrier 303 to move, the second air hole 304 continuously draws in air to perform secondary cleaning of dust and debris at both ends of the sleeve. When the carrier 303 moves to the bottom of the ramp 301, the baffle 305 is blocked by the limiting arm 307 and flips over, the sleeve automatically falls to complete the unloading, the baffle 305 then resets under the action of the torsion spring 306, and the equipment enters the next processing cycle;

[0043] In this embodiment, the feed drive mechanism and the transmission mechanism are known in the prior art transmission mechanical structures. Those skilled in the art can make adaptation selections as needed, and will not be described in detail here.

[0044] The method of use and advantages of this invention: The working process of this laser cutting machine for sleeve cutting based on disc buckle uprights is as follows:

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown:

[0046] S1: In the standby state of the equipment, each drive mechanism, hydraulic cylinder 207, vacuum cleaner 216, and transmission mechanism 302 are in the initial reset state, the protective cover 208 is in the open state, gear one 103 and gear two 104 are in normal meshing state, and the whole equipment is in the waiting-to-feed working condition.

[0047] During operation, the disc sleeve tube to be cut is first inserted through the feed holes 106 on both sides of the machine housing 101. The feed drive mechanism 102 drives the sleeve tube to be fed horizontally, so that the cutting position is accurately aligned with the cutting point below the laser cutting head 108. After the tube is inserted, the triangular claw disk 107 centers and clamps the end of the tube to ensure the stability of the center of the sleeve tube during the cutting process and avoid eccentric shaking that causes the cutting end face to tilt and the size deviation.

[0048] During the pipe feeding process, the cutting and processing component 200 is started synchronously, and the rack 206 and the gear 103 mesh and drive each other. The gear 103 drives the rack 206, thereby driving the mounting bracket 203 to move synchronously and approach the triangular claw disk 107. During the process, the protective cover 208 is always in the open state. After the pipe feeding is completed, the protective cover 208 is in place.

[0049] S2: At this time, the lower end of the laser cutting head 108 is directly between the two protective covers 208. Then, the laser cutting head 108 is controlled to move downward to perform the cutting operation. During the process, the two side arms 109 contact the surface of the guide frame 213. The inclined surface triggers and pushes the two protective covers 208 closer to each other, and finally completes the splicing, so that the protective covers 208 form a cylindrical cover on the outside of the pipe. The end of the laser cutting head 108 passes through the cutting hole 212 to cut the pipe. The triangular claw disk 107 drives the pipe to rotate to continuously switch the cutting point.

[0050] S3: The laser beam enters the sputtering cavity 211 through the cutting inlet 212 to precisely cut the rotating sleeve. Simultaneously, the vacuum cleaner 216 is activated. The vacuum cleaner 216, through the shrink box 214 and the evenly distributed air holes 215, temporarily retains the cut impurities in the sputtering cavity 211, effectively preventing them from overflowing. The shrink box 214 uses negative pressure to adsorb and collect the metal fumes, ultrafine metal dust, and high-temperature oil fumes generated during cutting inside the sputtering cavity 211. The shrink box 214 adopts a tapered structure with a large air inlet and a small air outlet, forming a convergent negative pressure effect, which greatly improves the dust adsorption efficiency and avoids dust overflow, lens contamination, and excessive dust in the working environment.

[0051] S4: After the sleeve is cut, the laser cutting head 108 is first raised upward and removed from the sputtering cavity 211. The two protective covers 208 open outward and remove the enclosure of the sleeve. The cut sleeve falls downward. Then the output shaft of the hydraulic cylinder 207 retracts, the rack 206 disengages from the gear 103, and automatically returns to its original position under the action of the elastic element 209 on the slide 202.

[0052] S5: The sleeve falls into the carrier 303. During the process, the transmission mechanism 302 drives the carrier 303 to move. The air holes 304 on both sides of the carrier 303 continuously suck in air under negative pressure to perform secondary dust suction and cleaning of the fine dust and burrs and debris remaining at the two cutting ends of the sleeve. At the same time, the baffle 305 hinged at the top of the carrier 303, together with the torsion spring 306, forms a one-way material blocking structure. When it reaches the bottom, it is blocked by the limiting arm 307, and the baffle 305 flips over, so that the sleeve that has undergone secondary dust removal is automatically released, completing the material unloading operation.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
