Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, and in particular to a full-protection three-chuck laser tube cutting device. Background Art

[0002] In modern manufacturing, laser cutting technology is widely used due to its high precision, high efficiency and high flexibility. As an advanced laser cutting equipment, the three-chuck laser cutting machine plays an important role in pipe processing and other fields.

[0003] With the increasing requirements for production safety and equipment stability, three-chuck laser cutting machines are facing a series of challenges. In the design of traditional three-chuck laser cutting machines, most of the research focuses on the degree of automation of laser cutting equipment, reducing the size of equipment, and the flexibility of the chuck. There is often a lack of effective protection measures for the driving source of the motion mechanism in the laser equipment or the high-energy laser beam generated by the laser cutting component. Since the driving source of the motion mechanism is exposed, there is a risk of accidental touch by the operator during operation. At the same time, the laser cutting components in the laser cutting area will generate high-intensity laser beams and high-temperature radiation when working. Without proper protection, it is easy to pose a serious threat to the personal safety of the operator. For example, laser radiation may damage the operator's eyes and skin.

[0004] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the invention

[0035] The present invention provides a fully protected three-chuck laser tube cutting device. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0036] See also Figure 1-Figure 2The present invention provides a fully protected three-chuck laser tube cutting equipment, comprising a side-hanging bed 1, a gantry 14 arranged on the side-hanging bed 1, a laser cutting component 2 that can reciprocate along the gantry 14 in the front-back and up-down directions, and a first chuck structure 41, a second chuck structure 42 and a third chuck structure 43 that can reciprocate along the left-right direction of the side-hanging bed 1; the gantry 14 divides the side-hanging bed 1 into a feeding area and a receiving area, a plurality of spaced mounting side seats 11 are arranged in the feeding area, a centering follower mechanism 31 is arranged on the mounting side seat 11, and a centering follower mechanism protection structure 32 is arranged on the outside of the centering follower mechanism 31; a plurality of feeding components 5 corresponding to the centering follower mechanism 31 are also arranged in the feeding area, the front ends of the plurality of feeding components 5 are respectively fixedly connected to the corresponding mounting side seats 11, and the rear ends of the plurality of feeding components 5 are connected by a feeding connecting rod 55, and the plurality of The feeding assembly 5 is used to transport the pipe from its rear end to the front end; the centering follower mechanism 31 is used to lift the pipe located at the front end of the feeding assembly 5; a plurality of spaced reinforced side seats 12 are arranged in the material receiving area, and a material receiving mechanism 7 fixedly connected to the side wall of the side-hanging bed 1 is arranged between the reinforced side seats 12; a plurality of material receiving assemblies 8 corresponding to the material receiving mechanism 7 are also arranged in the material receiving area, and the front ends of the plurality of material receiving assemblies 8 are respectively fixedly connected to the side walls of the side-hanging bed 1, and the rear ends of the plurality of material receiving assemblies 8 are connected by material receiving connecting rods; the material receiving mechanism 7 is used to perform follow-up support and tilted feeding of the pipe located in the material receiving area to the front end of the material receiving assembly 8; the plurality of material receiving assemblies 8 are used to transport the pipe from its front end to the rear end; a support 13 is arranged between the adjacent mounting side seats 11 and the reinforced side seats 12, and the front side of the gantry 14 is fixedly connected to the support 13; please refer to Figure 4-Figure 5 The support 13 and the gantry 14 are surrounded by a protective box 6, and the protective box 6 is used to enclose the laser cutting assembly 2 therein; a material unloading area 611 for unloading pipes is opened in front of the protective box 6, and avoidance areas 612 for the second chuck structure 42 and the third chuck structure 43 to pass through are opened on the left and right sides of the protective box 6, respectively; please refer to Figure 1 A first chuck protection structure 44 is disposed outside the first chuck structure 41 , a second chuck protection structure is disposed outside the second chuck structure 42 , and a third chuck protection structure 46 is disposed outside the third chuck structure 43 .

[0037] In actual application, the pipe to be cut is loaded to the rear end / upstream of the feeding assembly 5 by using a crane arm, and the feeding assembly 5 operates and gradually transports the pipes one by one to the front end / downstream, that is, to the lifting position of multiple centering follower mechanisms 31, and the pipe to be cut is lifted to be coaxial with the first chuck structure 41 and the second chuck structure 42 through the centering follower mechanism 31. The pipe will be clamped by the first chuck structure 41 and the second chuck structure 42 and pushed toward the laser cutting assembly 2 by the first chuck structure 41 to realize cutting and feeding. Therefore, the avoidance area 612 is opened on the left and right sides of the protective box 6 to avoid the corresponding chuck structure, and the cut pipe will be clamped by the third chuck structure 43, and with the cooperation of the material receiving mechanism 7, follow-up support and auxiliary feeding will be performed. Furthermore, since the second chuck structure 42 can move relative to the laser cutting assembly 2, when there is residual material left in the pipe, the laser cutting head of the laser cutting assembly 2 is vertically downward, reducing the distance between the second chuck structure 42 and the laser cutting assembly 2, and then directly cutting the remaining pipe, thereby reducing the amount of residual material, and the residual material / short material is discharged from the unloading area 611, and the unloading area 611 can be placed with a receiving box 76 for receiving the residual material / short material, without the need to transport it through the receiving assembly 8. At the same time, the unloading area 611 is also convenient for operators to enter the interior of the protective box 6 from here during the non-operating hours of the laser pipe cutting machine. When unloading is required, the receiving mechanism 7 tilts the unloading and transfers the pipe to the front end / upstream of the multiple receiving assemblies 8 spaced apart in the receiving area, operates through the receiving assembly 8, and transports the pipes that have been processed and cut one by one to the direction of their rear end / downstream, and unloading is achieved by using a crane or manual assistance.

[0038] The above-mentioned laser tube cutting equipment, by setting the centering follower mechanism protection structure 32, multiple chuck protection structures, and protection box 6, encloses the centering follower mechanism 31, the corresponding chuck drive mechanism, the gantry 14 and the laser cutting assembly 2 inside the corresponding structure. When the operator is located outside the protection structures and the protection box 6, it can effectively prevent the drive mechanisms from touching the operator, and can effectively prevent the scattering and reflection of the laser during the cutting process, so as to avoid the laser escaping and causing harm to the operator. In addition, by setting multiple feeding assemblies 5 corresponding to the centering follower mechanism 31 in the feeding area, the multiple feeding assemblies 5 are used to transport the pipes one by one to the lifting position of the centering follower mechanism 31; by setting the receiving mechanism 7 in the receiving area, the pipes in the cutting process or after the cutting are provided with follow-up support and auxiliary tilting feeding, and multiple receiving assemblies 8 are used to transport the pipes one by one to the feeding area 611, which can improve the automation of the tube cutting equipment, and can also keep the operator away from the laser tube cutting equipment, further improving the safety performance of the equipment.

[0039] Specifically, the laser cutting component 2 uses various driving mechanisms to enable the laser cutting head to reciprocate in the front-to-back and up-down directions. The laser cutting component 2 cooperates with three chuck structures that can be pushed in the left-right direction to achieve multi-directional cutting of the pipe. The laser cutting component 2 and the laser cutting head are both existing technologies and will not be described here.

[0040] More specifically, the centering follower mechanism protection structure 32, the protection box 6, etc. are all made of sheet metal parts, and related components such as air source processing can be centrally installed thereon for easy adjustment.

[0041] See also Figure 3-Figure 5 In some embodiments, a front protective curtain 68 is provided on the operating side of the protective box 6, and the front protective curtain 68 is used to shield the unloading area 611; side protective curtains 69 are provided on the left and right sides of the protective box 6, respectively, and the side protective curtains 69 are used to shield the avoidance area 612. The protective box 6 cooperates with the front protective curtain 68 and the side protective curtains 69 to achieve all-round laser protection. Moreover, the front protective curtain 68 has a lower manufacturing cost than the protective door, and it is more convenient to enter and exit the protective box 6. Specifically, the front protective curtain 68 and the side protective curtain 69 are preferably black fireproof curtains. Black has a strong shielding ability for the light generated by the laser, and the fireproof curtains are made of fireproof materials, which can prevent the fireproof curtains from melting due to heat, thereby extending the service life of the fireproof curtains.

[0042] See also Figure 3 , Figure 6 In some embodiments, the lower surface of the protective box 6 is provided with a first clip 63 and a second clip 64, and the upper part of the front protective curtain 68 and the upper part of the side protective curtain 69 are clamped between the first clip 63 and the second clip 64 by fasteners (specifically, the fasteners are screws / bolts / screws and nuts). In actual application, the first clip 63, the second clip 64 and the front protective curtain 68 or the side protective curtain 69 are modularly designed. When assembling, the modular whole can be installed to the corresponding position of the protective box 6. When the front protective curtain 68 and the side protective curtain 69 need to be replaced, the corresponding locking parts can be removed and the new front protective curtain 68 and the side protective curtain 69 can be replaced, which is convenient for disassembly and assembly. In addition, the first clip 63 and the second clip 64 cooperate with the fasteners to clamp and fix the upper part of the front protective curtain 68 and the side protective curtain 69. This connection method can ensure that the front protective curtain 68 and the side protective curtain 69 are stably attached to the protective box 6 during use.

[0043] See also Figure 3 , Figure 4In some embodiments, a viewing window 613 is provided in front of the protective box 6, and a transparent window 614 is provided in the viewing window 613. During the laser cutting operation, the operator needs to observe the situation in the cutting area in real time in order to timely understand the cutting progress, the pipe cutting status, and whether there are any abnormalities. The setting of the transparent window 614 enables the operator to clearly see the working conditions of the laser cutting assembly 2 in the protective box 6 through the viewing window 613 while ensuring his own safety, ensuring the smooth progress of the cutting work, while avoiding the risk of injury caused by direct exposure to laser radiation. Specifically, the transparent window 614 is preferably radiation-proof glass.

[0044] See also Figure 4 and Figure 5 In some embodiments, a baffle 65 is further provided between the side-mounted bed 1 and the gantry 14. The baffle 65 is located in the avoidance area 612, and the lower surface of the baffle 65 is fixedly connected to the upper surface of the support 13. In practical applications, the lower surface of one side of the gantry 14 is fixedly connected to the support 13, and the lower surface of the other side is fixedly connected to the side-mounted bed 1. Since there is a certain distance between the support 13 and the laser cutting assembly 2, a baffle 65 is provided. The baffle 65 cooperates with the protective box 6 to further reduce the escape of the laser in the cutting area. In order to further enhance the shielding effect of the baffle 65 on the laser, an arc groove matching the lower curvature of the second chuck structure 42 and the third chuck structure 43 is also provided on the upper part of the baffle 65.

[0045] See also Figure 5 In some embodiments, the support 13 is a hollow structure, and an exhaust pipe 66 is arranged between the support 13 and the side-mounted bed 1. The exhaust pipe 66 passes through the left and right sides of the support 13, and the front and rear sides of the side-mounted bed 1; the air inlet of the exhaust pipe 66 is connected to the inner cavity of the protective box 6. The exhaust pipe 66 is connected to the exhaust device. The above arrangement can quickly absorb the dust generated in the cutting area to protect the working environment. In addition, the generated dust adheres to the optical lens of the laser cutting head, which will reduce the light transmittance of the lens, cause the laser energy to attenuate, deteriorate the cutting quality, and increase the scrap rate. Therefore, quickly sucking away the dust can protect the laser cutting head and extend the service life of the laser cutting head. Moreover, the exhaust pipe 66 is relatively short, which makes full use of the position of the side-mounted bed 1 and the support 13, and the design is more reasonable.

[0046] See also Figure 4In some embodiments, a shield 67 is provided on the side wall of the support 13 facing the cutting area; the shield 67 is used to cover the air inlet of the exhaust pipe 66 inside the shield; and an exhaust hole 671 is also provided on the shield 67. The shield 67 covers the air inlet of the exhaust pipe 66, and can effectively guide the smoke and exhaust gas generated during the laser cutting process to flow to the exhaust hole 671. In addition, the cutting area also involves the unloading area 611, so the setting of the shield 67 can also prevent the short tube / tail material from directly contacting the exhaust pipe 66 after falling and damaging the exhaust pipe 66.

[0047] See also Figure 7 and Figure 8 In some embodiments, a distance measuring mechanism 411 is disposed on the outside of the first chuck structure 41, and the distance measuring mechanism 411 is used to measure the distance from the left end of the pipe loaded to the centering follower mechanism 31; the side walls of the gantry 14 in the front and rear directions are respectively provided with a shooting sensor (not shown in the figure); the shooting sensor is used to cooperate with the distance measuring mechanism 411 to sense the position of the right end of the pipe loaded to the centering follower mechanism 31 and measure the length of the pipe to be cut; the first chuck protection structure 44 includes a first protective cover 441 for enclosing the first Y-axis side hanging plate 471, the first Y-axis side hanging plate driving mechanism 472, the first chuck driving mechanism and the distance measuring mechanism 411 therein; the first protective cover 441 is provided with an avoidance hole 442 on the side wall facing the laser cutting assembly 2 to avoid the distance measuring mechanism 411. In this embodiment, the first Y-axis side hanging plate driving mechanism 472 can be driven by a motor, a gear and a rack. The first chuck structure 41 is fixedly connected to the first Y-axis side hanging plate 471, so the first Y-axis side hanging plate 471 can drive the first chuck structure 41 to move back and forth along the length direction of the side hanging bed 1. In actual application, the pipe fed to the centering follower mechanism 31 needs to be driven by the first Y-axis side hanging plate driving mechanism 472 to move toward the left end of the pipe. According to the setting of the program, after the first chuck structure 41 moves to the set position, the distance measuring mechanism 411 is used to extend to the right and touch the left end of the pipe to measure the distance from the first chuck structure 41 to the left end of the pipe, so that the first chuck structure 41 can be firmly clamped to the left end of the pipe to avoid the occurrence of empty clamping of the pipe. Specifically, the distance measuring mechanism 411 is a cylinder, a moving plate, and a stroke sensor. By extending the output end of the cylinder, the movable plate is extended from the avoidance hole 442, and the travel sensor is used to measure the movement stroke of the movable plate. The pipe clamped by the first chuck structure 41 is pushed to the right until the right end of the pipe blocks the two opposing sensors, and the actual length of the pipe can be calculated by signal conversion, thereby achieving precise cutting. The first chuck protection structure 44 can enclose the first Y-axis side hanging plate drive mechanism 472 and the first chuck drive mechanism inside it to avoid exposure of the drive mechanism.

[0048] See also Fig. 9 and Fig.10 In some embodiments, the second chuck protection structure and the third chuck protection structure 46 both include a first protective cover 461 surrounding the second Y-axis side hanging plate, the second Y-axis side hanging plate driving mechanism / the third Y-axis side hanging plate 473, and the third Y-axis side hanging plate driving mechanism 474, a second protective cover 463 surrounding the second chuck driving mechanism / the third chuck driving mechanism, and a fixed cover 462 whose two ends are respectively connected to the side walls of the first protective cover 461 and the second protective cover 463; the fixed cover 462 is used to be fixedly connected to the outer side wall of the second chuck structure 42 / the third chuck structure 43. In practical applications, the first protective cover 461 is used to cover the second Y-axis side hanging plate and the driving mechanism thereon, the third Y-axis side hanging plate 473 and the driving mechanism thereon, and the second protective cover 463 is used to cover the driving mechanism on the second chuck / the third chuck, which can effectively prevent the operator from contacting the driving mechanism, reduce the probability of safety accidents, and ensure the personal safety of the operator. In addition, it can prevent foreign matter from entering the driving mechanism and interfering with the operation of the driving mechanism; it can also make the appearance of the laser tube cutting machine more neat and beautiful. The fixed cover 462 is used to connect the first protective cover 461 and the second protective cover 463, so that the chuck protection structure forms a whole, which is convenient for installing the entire chuck protection structure on the laser tube cutting machine, or removing the entire chuck protection structure from the laser tube cutting machine.

[0049] Specifically, the second Y-axis side hanging plate driving mechanism and the third Y-axis side hanging plate driving mechanism 474 can be driven by a motor, a gear and a rack, and the driving mechanism is a prior art.

[0050] See also Fig.10 For more details, please refer to Figure 4 The second chuck structure 42 is provided with a group of four large rollers 431 arranged in the up-down and left-right directions, and a group of four small rollers 432 arranged in the up-down and left-right directions. Fig. 9The third chuck structure 43 is provided with a group of four large rollers 431 arranged in the up, down, left and right directions, a group of two small rollers 432 arranged in the left and right directions, and a group of two clamps 433 arranged in the up and down directions. The chuck structure in which the clamps 433 and the rollers cooperate is adopted, so that the third chuck structure 43 can be moved to the left side of the laser cutting assembly 2, that is, the three chuck structures clamp the pipe at the same time. In addition, the multiple groups of roller groups are provided, so that the positions of the second chuck structure 42 and the third chuck structure 43 can remain unchanged, and the first chuck structure 41 can be used to push the pipe, and the sliding force provided by the roller group is used to provide avoidance for the advancement of the pipe. The cooperation of multiple groups of large rollers 431 and small rollers 432, as well as the clamps, enables the clamping method of the chuck structure to have a variety of combinations, which can be adapted to pipe cutting in more application scenarios.

[0051] In some embodiments, a chuck protection plate is disposed in the inner cavity in the middle of the second chuck structure 42 and the third chuck structure 43. The chuck protection plate is used to protect the inner cavity of the chuck structure.

[0052] See also Fig. 9 In some embodiments, the first protective cover 461 includes a first cover body 4611 and a first inspection plate 4612 detachably connected to the first cover body 4611 by bolts / screws / screws; the first cover body 4611 is provided with a first inspection opening that matches the shape of the first inspection plate 4612, and the first inspection plate 4612 is used to cover the first inspection opening. The first protective cover 461 is made of sheet metal, and the first inspection opening is formed on the first protective cover 461, so that the driving mechanism inside the first protective cover 461 can be inspected through the first inspection opening after the first inspection plate 4612 is removed.

[0053] See also Fig. 9 In some embodiments, the second protective cover 463 includes a second cover body 4631 and a second inspection plate 4633 detachably connected to the second cover body 4631 by bolts / screws / screws; the second cover body 4631 is provided with a second inspection opening that matches the shape of the second inspection plate 4633, and the second inspection plate 4633 is used to cover the second inspection opening. Similarly, the second protective cover 463 is made of sheet metal, and by forming the second inspection opening on the second protective cover 463, it is convenient to inspect the driving mechanism inside the second protective cover 463 through the second inspection opening after the second inspection plate 4633 is removed.

[0054] See also Fig. 9In some embodiments, the side wall and the bottom of the second cover body 4631 are provided with heat dissipation holes 4632. During the operation of the device, the chuck drive mechanism generates heat. If the heat cannot be dissipated in time, the temperature inside the mechanism will rise. The heat dissipation holes 4632 provided on the side wall and the bottom can form a good heat dissipation channel, allowing the heat to be dissipated to the external environment in time, so that the chuck drive mechanism can continue to operate stably within a suitable temperature range. In this embodiment, the bottom of the first cover body 4611 is an open structure, so there is no need to set additional heat dissipation holes 4632.

The above-mentioned fixed cover 462 is adapted to the shape of the second chuck structure 42 / third chuck structure 43. In practical applications, the first extension section 4621, the second extension section 4623 of different lengths or the arc section 4622 of different arcs can be designed to make the chuck protection structure adapt to chuck structures with different arc specifications. In addition, each part of the three-section fixed cover 462 is connected to other parts of the equipment, thereby ensuring that the chuck protection structure is firmly installed and easy to assemble, and the three parts of the fixed cover 462 can be fixed to the equipment in a distributed manner.

[0056] See also Figure 7 and Fig. 9In some embodiments, the first chuck protection structure 44, the second chuck protection structure and the third chuck protection structure 46 are all provided with a Y-axis drag chain fixing seat 464 connected to the first chuck protection structure 44 / the second chuck protection structure / the third chuck protection structure 46 on the outside, and the Y-axis drag chain fixing seat 464 is used to be fixedly connected to the end of the Y-axis drag chain. The Y-axis drag chain is used to accommodate and protect various cables, air pipes and other pipelines so that they can follow and move in an orderly manner during the movement of the equipment. The setting of the Y-axis drag chain fixing seat 464 provides a special fixed position for the Y-axis drag chain, ensuring that the Y-axis drag chain can be accurately located on the predetermined path when the equipment is running, avoiding the Y-axis drag chain from swinging randomly or interfering with other components, and making the wiring inside the equipment more standardized and neat. In addition, the Y-axis drag chain fixing seat 464 provides a clear position and connection method for the installation of the Y-axis drag chain. The operator only needs to fix the end of the Y-axis drag chain on the Y-axis drag chain fixing seat 464 to complete the installation. The operation is simple and convenient; it is also conducive to regular maintenance and replacement.

[0057] See also Figure 5 In some embodiments, the centering follower mechanism protection structure 32 includes a first protection plate 321 for being fixedly connected to the corresponding mounting side seat 11, and a second protection plate 323 for being fixedly connected to the front side wall of the side-mounted bed 1; a lap plate 322 is provided on the side wall of the first protection plate 321 facing the second protection plate 323, and the lap plate 322 and the inner side wall of the second protection plate 323 are fixedly connected by bolts after abutting against each other; the first protection plate 321, the second protection plate 323, the mounting side seat 11, and the side-mounted bed 1 form a space for installing the centering follower mechanism 31. In actual application, the centering follower mechanism 31 is located on the operating side of the side-mounted bed 11. By enclosing the centering follower mechanism 31 in the space surrounded by the first protective plate 321, the second protective plate 323, the mounting side seat 11 and the side-mounted bed 1, the operator can be effectively prevented from accidentally contacting the centering follower mechanism 31, and the operator can be prevented from being injured by accidentally touching the centering follower mechanism 31 that is running or stationary, such as mechanical injuries such as pinching and abrasion, thereby ensuring the personal safety of the operator. In addition, when installing the first protective plate 321 and the second protective plate 323, or when the centering follower mechanism 31 needs to be maintained or repaired, the protective structure can be relatively easily disassembled and installed through the connection method of the lap plate 322 and the bolts, which improves the disassembly and assembly speed and reduces the difficulty and time cost of maintenance work.

[0058] Furthermore, the structure is open at the top and bottom, which makes it easy to observe the operation of the centering follower mechanism 31 from the outside and is beneficial to heat dissipation.

Specifically, multiple pipes are respectively limited in their respective feeding and storage bayonet, which can prevent the pipes from being displaced and ensure that the conveying speed of each pipe is consistent. The feeding rotation drive device 54 and the feeding transmission shaft 531 are used to realize the synchronous operation of multiple feeding and transporting chains 523, which has a simple structure and a high synchronization rate. In addition, the feeding driving wheel 521, the feeding driven wheel 522 and the feeding and transporting chain 523 are conventional chain transmission parts. The feeding limiting block 524 is assembled on the feeding and transporting chain 523 to form the feeding and storage bayonet, which has low manufacturing difficulty and low cost.

[0060] Specifically, the provision of the feed axis limiting plate 514 can prevent the pipe from easily sliding out / rolling out of the feed assembly 5 due to the inertia of the pipe moving forward. The feed axis limiting plate 514 is used to limit the movement of the pipe and improve safety.

[0061] More specifically, the feeding rotating drive device 54 is arranged away from the bed, which is the operating side. Therefore, the feeding protective cover 56 is provided to cover the feeding rotating drive device 54 therein, which can be used to protect the operator at the operating side.

[0062] Each set of feeding components 5 of the present embodiment is of detachable design, which occupies little space and is convenient for shipment and transportation after detachment.

[0063] See also Fig.11In some embodiments, the feeding frame 51 includes a feeding crossbeam 511 parallel to the conveying direction of the pipe, a first feeding vertical beam 512 fixedly connected to the front of the feeding crossbeam 511, and a second feeding vertical beam 513 fixedly connected to the rear of the feeding crossbeam 511; the adjacent second feeding vertical beams 513 are connected by the feeding connecting rod 55. Specifically, the feeding crossbeam 511, the first feeding vertical beam 512 and the second feeding vertical beam 513 are all square tubes, which are light in weight and easy to obtain. The front end of the feeding crossbeam 511 is fixedly connected to the side-hanging bed 1, and the feeding connecting rod 55 is used to realize the fixing of multiple feeding crossbeams 511, so that the multiple feeding components 5 form a structure that is easy to disassemble and install, which is convenient for shipment and transportation and on-site installation.

[0064] See also Fig.13 In some embodiments, the feeding driving wheel 521 is sleeved on the feeding rotating shaft 5211, and the feeding rotating shaft 5211 is connected to the feeding beam 511 through two feeding belt seat bearings 5212, and one end of the feeding rotating shaft 5211 is connected to the feeding transmission shaft 531 through a feeding universal joint coupling 532; the feeding rotation driving device 54 includes a feeding motor bracket 541, a feeding driving motor 542 arranged on the feeding motor bracket 541, a feeding driving sprocket 543 arranged on the output end of the feeding driving motor 542, a feeding driven sprocket 544 sleeved on one of the feeding rotating shafts 5211, and a feeding driving chain 545 wound between the feeding driving sprocket 543 and the feeding driven sprocket 544. When transporting pipes, the feeding drive motor 542 drives the feeding active sprocket 543 to rotate, and under the transmission of the feeding drive chain 545 and the feeding driven sprocket 544, the feeding shaft 5211 is driven to rotate, and then the feeding active wheel 521 on the feeding shaft 5211 is driven to rotate, providing power for the feeding transport chain 523. In addition, when one of the feeding shafts 5211 rotates, the power is transmitted to the other feeding shaft 5211 through the feeding universal joint coupling 532, the feeding transmission shaft 531 and the feeding universal joint coupling 532, thereby realizing the synchronous rotation of multiple feeding transport chains 523.

[0065] See also Fig.12In some embodiments, the feed protection cover 56 includes a feed motor cover 561 and a feed transmission cover 563 connected to the inner cavity of the feed motor cover 561; the feed motor bracket 541 and the feed drive motor 542 are covered inside the feed motor cover 561; the feed driving sprocket 543, the feed driven sprocket 544 and the feed drive chain 545 are covered inside the feed transmission cover 563. Splitting the feed protection cover 56 into two parts not only facilitates the preparation of sheet metal parts and reduces the manufacturing difficulty, but also makes the shape of the feed protection cover 56 more suitable for the shape of the feed rotation drive device 54, reducing the space occupied by the feed rotation drive device 54.

[0066] See also Fig.12 In some embodiments, a feeding inspection port is provided on the feeding motor cover 561, and a detachable feeding cover plate 562 is provided in the feeding inspection port. With the above arrangement, the feeding cover plate 562 can be opened to expose the feeding rotation drive device 54, so as to perform maintenance without disassembling the entire feeding protective cover 56.

[0067] See also Fig.11 and Fig.12 , see Figure 2 In some embodiments, a feeding guard plate 515 is provided at the rear end of the feeding beam 511, and the feeding guard plate 515 is used to shield the rear end of the feeding driving wheel 521. The rear end is the operating side, and the feeding guard plate 515 provided can shield the feeding driving wheel 521, thereby further preventing clothes or other items from being rolled in.

[0068] See also Fig.14 and Fig.15 In some embodiments, the material receiving mechanism 7 includes a base 71, a movable plate 72 movably disposed on the base 71, a lifting drive 73 for driving the movable plate 72 to rise or fall, a material receiving plate 74 having one end surface rotatably connected to the upper part of the movable plate 72, and a material receiving drive 75 fixed to the movable plate 72 and used to drive the material receiving plate 74 to tilt horizontally or downwardly. The lifting drive 73 drives the movable plate 72 to follow the pipe material to rise and fall, thereby changing the height of the material receiving plate 74 relative to the pipe material (especially for non-circular pipes). When the pipe material needs to be supported, the material receiving drive 75 drives the material receiving plate 74 to be in a horizontal state, and then the movable plate 72 and the material receiving plate 74 move up and down; when the pipe material needs to be unloaded, the material receiving drive 75 drives the material receiving plate 74 to be in an inclined state, thereby guiding the pipe material placed on the material receiving plate 74 to the front end of the material receiving assembly 8.

[0069] See also Fig.14 and Fig.15In some embodiments, the material receiving mechanism 7 further includes a lower protective cover 77, an upper protective plate 78 and a side protective plate 79; the lower protective cover 77 is located below the material receiving plate 74 and is used to cover the movable plate 72, the lifting drive member 73 and the material receiving drive member 75 therein; the upper protective plate 78 is fixedly connected to the movable plate 72 and is located above the base 71; the side protective plate 79 is located on the outer side of the lower protective cover 77 close to the side protective plate 79. The lower protective cover 77 and the upper protective plate 78 cooperate with the material receiving plate 74 to isolate the laser to the greatest extent, thereby protecting the material receiving mechanism 7 from being damaged by the laser when the laser tube cutting equipment performs cutting work. In order to provide a downwardly inclined avoidance space for the material receiving plate 74 so that there is a gap between the side plate and the material receiving plate 74, the side protective plate 79 is provided to further block the laser generated by the laser cutting assembly 2, thereby further improving the protection effect.

[0070] See also Fig.14 In some embodiments, the width of the lower protective cover 77 is smaller than the width of the receiving plate 74, and the length of the lower protective cover 77 is smaller than the length of the receiving plate 74. That is to say, the overall size of the lower protective cover 77 is smaller than the size of the receiving plate 74, so that the receiving plate 74 can completely cover the upper part of the lower protective cover 77, thereby ensuring that the movable plate 72, the lifting drive member 73, the receiving drive member 75 and other components inside the lower protective cover 77 are not affected by the laser.

[0071] See also Fig.14 In some embodiments, the rear side of the side protection plate 79 is provided with an outwardly bent avoidance plate 791, and the avoidance plate 791 is used to avoid the side wall of the upper protection plate 78 located behind it. As described above, the material receiving plate 74 can be tilted downward, so when the material receiving plate 74 tilts downward, it will simultaneously drive the side protection plate 79 to tilt. Therefore, in order to prevent the side protection plate 79 from touching the outer side wall of the upper protection plate 78, the outwardly bent avoidance plate 791 is provided.

[0072] See also Fig.15In some embodiments, the lifting drive member 73 includes a lifting drive motor 731, a transmission gear 732 connected to the output end of the lifting drive motor 731, and a transmission rack 733 arranged on the front side of the base 71; the output end of the lifting drive motor 731 passes through the front and rear side walls of the movable plate 72; the transmission rack 733 is vertically extended and arranged on the base 71; the transmission gear 732 is meshed with the transmission rack 733. When in use, when the lifting drive motor 731 rotates forward, it drives the transmission gear 732 to rotate forward, and under the guidance of the transmission rack 733, the movable plate 72 and the receiving plate 74 are synchronously raised. On the contrary, when the lifting drive motor 731 rotates reversely, it drives the transmission gear 732 to rotate reversely, so that the movable plate 72 and the receiving plate 74 are synchronously lowered. The above structure has high transmission efficiency and high transmission accuracy.

[0073] Specifically, the lifting drive motor 731 is a servo motor, which has a brake function, which can prevent the pipe from falling and causing safety hazards due to a sudden power failure of the lifting drive motor 731 when the pipe is cut, supported or connected.

[0074] See also Fig.15 In some embodiments, the material receiving driving member 75 is a material receiving cylinder that is arranged obliquely.

[0075] In some embodiments, the plurality of material receiving components 8 each include a material receiving frame, a material receiving active wheel rotatably disposed on the material receiving frame, a material receiving driven wheel, and a material receiving transport chain wound between the material receiving active wheel and the material receiving driven wheel, a plurality of material receiving limiting blocks are disposed on the outer side of the material receiving transport chain, a material receiving storage bayonet is formed between two adjacent material receiving limiting blocks, the material receiving active wheels on the plurality of material receiving components 8 are connected by a material receiving transmission shaft, the material receiving transmission shaft is connected by a material receiving rotation drive device; the external cover of the material receiving rotation drive device is provided with a material receiving protective cover body; the rear end of the material receiving frame is provided with a material receiving limit axis plate 81, the material receiving limit axis plate 81 is used to prevent the pipe from continuing to be transported to the rear. Please refer to Figure 1 According to the above records, the material receiving assembly 8 and the material feeding assembly 5 are basically the same in structure, and the main difference is that: according to the conveying inertia of the pipe, the material receiving limit axis plate 81 is set at the downstream, and the material feeding limit axis plate 514 is set at the upstream. In addition, the front end of the feeding frame 51 is fixedly connected to the mounting side seat 11, and the front end of the material receiving frame is fixedly connected to the side wall of the side hanging bed 1. The feeding assembly 5 and the material receiving assembly 8 adopt a basically similar structure, one for feeding and the other for receiving, which can further simplify the complexity of the pipe cutting equipment and reduce the manufacturing cost.

[0076] See also Fig.16In some embodiments, a stroke sensing mechanism 82 for sensing the pipe is further provided in front of the material receiving limit axis plate 81; the stroke sensing mechanism 82 includes a support plate 821 fixed on the side wall of the material receiving frame, a stroke switch 822 provided on the support plate 821, and a material arrival pressing plate 823 provided on the output end of the stroke switch 822. In order to automatically detect whether the pipe is transported to the set position, the stroke sensing mechanism 82 is provided. When the pipe triggers the stroke sensing mechanism 82, it means that the pipe is transported to the position. At this time, the stroke sensing mechanism 82 feeds back a signal to the control system, and the control system controls the material receiving rotation driving device to stop working until the pipe is unloaded. The material receiving rotation driving device restarts to realize the automatic material receiving and transportation of the next pipe. Specifically, when the pipe is conveyed to the position of the material receiving pressure plate 823, the material receiving pressure plate 823 is pressed down, triggering the travel switch 822, and the control system controls the material receiving rotating drive device to stop the conveyance of the pipe. After the pipe is unloaded and transferred to leave the material receiving frame, the material receiving rotating drive device will start again. The above-mentioned setting cooperates with the material receiving mechanism 7 to realize fully automatic material receiving and feeding.

[0077] See also Fig.16 In some embodiments, a photoelectric sensor 831 is further provided upstream of the material receiving pressing plate 823 (the figure indicates a mounting plate of the photoelectric sensor 831), and a plurality of sensing sheets 832 corresponding to the material receiving and storing bayonet are fixedly connected to the material receiving and transporting chain, and the photoelectric sensor 831 is used to sense the sensing sheets 832. When the sensing sheets 832 pass the position of the photoelectric sensor 831, the material receiving and transporting chain stops moving, and the material receiving mechanism 7 will transfer the next pipe to the upstream of the material receiving and transporting chain after the pipe at the downstream end of the material receiving and transporting chain is unloaded.

[0078] In summary, the present invention, through the arrangement of the centering follower mechanism protection structure 32, multiple chuck protection structures, and the protection box 6, encloses the centering follower mechanism 31, the corresponding chuck drive mechanism, the gantry 14, and the laser cutting assembly 2 inside the corresponding structure. When the operator is outside the protection structures and the protection box 6, it can effectively prevent the drive mechanisms from touching the operator, and can effectively prevent the scattering and reflection of the laser during the cutting process, thereby preventing the laser from escaping and causing harm to the operator. In addition, by arranging multiple feeding assemblies 5 corresponding to the centering follower mechanism 31 in the feeding area, the multiple feeding assemblies 5 are used to transport the pipes one by one to the lifting position of the centering follower mechanism 31; by arranging the receiving mechanism 7 in the receiving area, the pipes in the cutting process or after the cutting are provided with follow-up support and auxiliary tilting feeding, and by using multiple receiving assemblies 8 to transport the pipes one by one to the feeding area 611, the automation degree of the pipe cutting equipment can be improved, and the operator can be kept away from the laser pipe cutting equipment, thereby further improving the safety performance of the equipment.
