Description

Technical Field

[0001] This application relates to the field of steel pipe processing technology, and in particular to an improved laser cutting machine. Background Technology

[0002] Improved laser cutting machines, with their higher cutting precision, faster processing efficiency, wider material adaptability (covering metals, non-metals, composite materials, etc.) and more intelligent operation control system, are widely used in the processing of complex parts in precision machinery manufacturing and the fine cutting of body parts in the automotive industry.

[0003] A search revealed Chinese publication number CN219724993U, which discloses a laser cutting machine for steel pipe processing. The machine includes an operating table with two sets of fixed plates fixedly mounted on its top. Each set of plates has a fixed rod fixedly mounted between it. Rollers are rotatably mounted on the outer surfaces of both fixed rods. A cutting machine is mounted on the top of the operating table, along with a fixed frame and a waste chip collection mechanism. This laser cutting machine for steel pipe processing utilizes a combination of a rotary motor, threaded rod, threaded block, and vertical rod. The rotary motor, when activated, moves the dust collection hood via the vertical rod, achieving a large-area dust collection effect. The dust collector is designed to suck up and collect waste chips generated during steel pipe cutting. Through the interaction of a through-slot and a collection box, large pieces of waste chipping generated during steel pipe cutting fall directly into the collection box via the through-slot.

[0004] The patent description mentions that "the steel pipe can be placed on two rollers, and the rollers are designed to position the steel pipe." When the steel pipe cannot be held stably and accurately, it is prone to displacement, shaking, or rotation during laser cutting. This can cause the cutting trajectory to deviate from the preset path, resulting in problems such as dimensional errors, skewed cuts, and inconsistent bevel angles. In severe cases, it may even render the workpiece unusable. To address these issues, an improved laser cutting machine is proposed. Utility Model Content

[0005] The purpose of this application is to provide an improved laser cutting machine that addresses the problem that some existing laser cutting machines cannot adaptively clamp steel pipes.

[0006] The improved laser cutting machine provided in this application adopts the following technical solution:

[0007] An improved laser cutting machine includes a worktable and a sliding block. An electric guide rail is fixedly connected to the outer right side of the sliding block. A laser cutting head is slidably connected to the outer side of the electric guide rail. Fixed plates are fixedly connected to the left and right sides of the inside of the worktable. An adaptive fixing mechanism is fixedly connected to the top of the fixed plate. A quantitative feeding and anti-collision mechanism is fixedly connected to the bottom of the inside of the worktable.

[0008] The adaptive fixing mechanism includes a mounting frame, which is externally fixedly connected to the outside of the fixing plate. Support rods are fixedly connected to the front and rear sides of the top of the mounting frame. Sliding pressure rods are slidably connected to the outside of the support rods. A limit elastic component is fixedly connected to the middle of the outside of the sliding pressure rod. An extrusion rod is slidably connected to the inside of the sliding pressure rod. A mounting bracket is fixedly connected to the bottom of the extrusion rod. Extrusion wheels are fixedly connected to the left and right sides of the outside of the mounting bracket.

[0009] The above solution allows the adaptive fixing mechanism to adjust the height through the cooperation of the sliding pressure rod and the support rod. The limiting elastic component provides stable pressure, and the extrusion wheel slides with the extrusion rod to adaptively fit the workpiece. This not only flexibly adapts to workpieces of different sizes, but also ensures a stable fixation through elastic pressure, preventing workpiece displacement during cutting. At the same time, the extrusion wheel reduces friction damage, improving the accuracy and ease of operation of laser cutting.

[0010] As a further description of the above technical solution:

[0011] The mounting bracket has support plates fixedly connected to both the front and rear sides of its top, and two auxiliary wheels are rotatably connected inside the support plates.

[0012] The above solution involves a support plate at the top of the mounting frame that is rotatably connected to two auxiliary wheels. These wheels assist in supporting the workpiece and allow it to roll as it moves, reducing frictional resistance between the workpiece and the mounting frame and preventing scratches on the workpiece surface. At the same time, the two wheels work together to enhance lateral positioning of the workpiece, preventing it from shifting during laser cutting, improving feeding smoothness and cutting accuracy, and making the operation more labor-saving and efficient.

[0013] As a further description of the above technical solution:

[0014] The limiting elastic assembly includes a mounting housing, with a limiting plate slidably connected inside the mounting housing, and a return spring sleeved on the outside of the compression rod.

[0015] The above solution involves a return spring sleeved outside the extrusion rod in the limiting spring assembly. The limiting plate slides within the mounting housing. When the workpiece is placed, the extrusion wheel pushes the extrusion rod, causing the limiting plate to compress the spring. The force generated by the spring's rebound is used by the extrusion wheel to adaptively press the workpiece. This design utilizes the spring force to automatically adjust the pressing force, adapting to workpieces of different thicknesses, avoiding overpressure damage, ensuring stable fixation, and improving the stability and safety during laser cutting.

[0016] As a further description of the above technical solution:

[0017] The quantitative feeding anti-collision mechanism includes a collection box, which is fixedly connected to the bottom of the workbench. A through-hole plate is fixedly connected to the top of the collection box. A connecting shaft is rotatably connected to the inside of the through-hole plate. Multiple quantitative baffles are fixedly connected to the outside of the connecting shaft. A telescopic rod is fixedly connected to the bottom of the collection box. A mounting spring is sleeved on the outside of the telescopic rod.

[0018] The above solution involves a connecting shaft that drives a quantitative baffle to rotate, allowing cutting waste to fall quantitatively into the collection box through a perforated plate. The telescopic rod, in conjunction with a spring, buffers the impact of the falling waste. This design controls the feeding speed through the quantitative baffle to prevent accumulation and blockage, while the spring buffer reduces damage from collisions between the waste and the box. This ensures collection efficiency while protecting the integrity of the waste, thus improving the waste processing capacity and practicality of the laser cutting machine.

[0019] As a further description of the above technical solution:

[0020] The worktable is slidably connected to a sliding guide rail, and a hydraulic cylinder is fixedly connected to the top of the sliding guide rail. The sliding block is fixedly connected to the drive end of the hydraulic cylinder.

[0021] The above solution involves the sliding cooperation between the worktable and the sliding guide rail, combined with the hydraulic cylinder driving the sliding block to move, which allows for flexible adjustment of the laser cutting head position. The hydraulic cylinder provides stable driving force, and the sliding guide rail ensures precise and smooth movement, adapting to the cutting needs of workpieces of different sizes. This design enables flexible adjustment of the cutting head in multiple directions, improving the cutting range and accuracy, making operation convenient and efficient, and enhancing the adaptability and working efficiency of the laser cutting machine.

[0022] As a further description of the above technical solution:

[0023] A rubber plate is fixedly connected to the outer top of the telescopic rod, and the outer side of the rubber plate is slidably connected to the inside of the collection box.

[0024] The above solution involves a rubber plate at the top of the telescopic rod sliding inside the collection box, forming a buffer structure with the installed spring. When the falling cutting waste comes into contact with the rubber plate, the rubber plate compresses the spring along with the telescopic rod. Through the double buffering effect of elastic deformation and spring force, the impact force between the waste and the collection box is greatly reduced, preventing damage to the waste and the box body due to bumps. At the same time, the rubber material reduces friction scratches, protects the integrity of the waste, and improves the protective performance of the collection mechanism.

[0025] As a further description of the above technical solution:

[0026] The limiting plate is externally fixedly connected to the inside of the extrusion rod, and the outer top end of the mounting bracket is in contact with the outer bottom end of the sliding pressure rod.

[0027] The above solution involves fixing the limiting plate inside the extrusion rod, which, together with the top of the mounting bracket, contacts the bottom of the sliding pressure rod to form a stable force transmission structure. When the extrusion rod is under force, the limiting plate restricts its excessive sliding, while the mounting bracket evenly transmits the pressure to the sliding pressure rod, ensuring the stability of the force value of the elastic component. This design avoids component misalignment or force imbalance, ensures that the clamping force of the extrusion wheel on the workpiece is precise and controllable, and improves the stability and adaptability of workpiece fixation during laser cutting.

[0028] As a further description of the above technical solution:

[0029] One end of the reset spring is fixedly connected to the outer top of the mounting bracket, and the other end of the reset spring is fixedly connected to the outer bottom of the limiting plate.

[0030] The above solution involves connecting the two ends of the reset spring to the top of the mounting bracket and the bottom of the limiting plate, respectively. When the workpiece is squeezed, the mounting bracket pushes the spring to compress, and the spring stores its force. When the pressure disappears, the spring rebounds and drives the mounting bracket to reset. This design automatically adjusts the height of the mounting bracket by means of the spring force, adapting to workpieces of different thicknesses, ensuring that the extrusion wheel always presses the workpiece smoothly, avoiding overpressure damage, and improving the flexibility and reliability of the fixing mechanism.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. In this utility model, the steel pipe is placed on the support plate, the extrusion wheel pushes the extrusion rod to compress the return spring, and the spring force makes the steel pipe firmly fixed. The auxiliary wheel helps the steel pipe to rotate and adjust the cutting position, which is flexible and convenient. After the steel pipe is removed, the spring automatically rebounds, and the extrusion wheel and the auxiliary wheel return to their original positions and fit together. This design adapts to fixing steel pipes of different specifications, taking into account both the stability of the fixation and the flexibility of adjustment, improving the cutting efficiency and the convenience of operation, and ensuring the accuracy of laser cutting.

[0033] 2. In this utility model, after the steel pipe is cut and falls, it pushes the quantitative baffle to rotate so that it falls into the collection box in an orderly manner. When it comes into contact with the rubber plate, it squeezes the telescopic rod and the installed spring. The spring deforms to buffer the impact. This design uses the weight of the steel pipe to achieve quantitative feeding, avoids accumulation and chaos. At the same time, the spring and the rubber plate provide double buffering to prevent collisions and prevent the steel pipe from falling and getting damaged. This ensures the orderly collection and the integrity of the workpiece, and improves the efficiency and safety of post-cutting processing. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0040] Example: Improved laser cutting machine, see reference. Figures 1 to 3 The system includes a worktable 1 and a sliding block 4. An electric guide rail 5 is fixedly connected to the outer right side of the sliding block 4, providing a track for the lateral movement of the laser cutting head 6. This allows the laser cutting head 6 to be precisely positioned horizontally under the drive of the electric guide rail 5, thus meeting the cutting needs of workpieces of different sizes and shapes. The laser cutting head 6 is slidably connected to the outer side of the electric guide rail 5. The laser cutting head 6 is the core component for realizing the cutting function, integrating a high-power laser generator, a focusing lens, and other components. The high-energy laser beam generated by the laser generator is focused by the focusing lens to form a spot with extremely high energy density, which acts on the surface of the workpiece, causing the irradiated area to rapidly melt or even vaporize, thereby achieving the cutting operation. The sliding of the laser cutting head 6 on the electric guide rail 5 can cooperate with the movement of the sliding block 4 to achieve all-round cutting of the workpiece. The worktable 1 is fixedly connected to the left and right sides of the interior with fixed plates 9. The top of the fixed plates 9 is fixedly connected to the self-adaptive fixing mechanism 7. The bottom of the worktable 1 is fixedly connected to the quantitative feeding anti-collision mechanism 8. The quantitative feeding anti-collision mechanism 8 includes a collection box 81, which can collect the workpieces after cutting to prevent them from falling to the ground and causing damage or loss.

[0041] Specifically, the workpiece is fixed by the self-adaptive fixing mechanism 7 supported by the fixed plates 9 on the left and right sides of the worktable 1. The electric guide rail 5 on the right side of the sliding block 4 drives the laser cutting head 6 to move laterally. The movement of the sliding block 4 achieves all-round cutting. The laser cutting head 6 generates a high-energy light spot through a high-power laser generator and focusing lens, which melts or vaporizes the irradiated area of ​​the workpiece to complete the cutting. The collection box 81 of the quantitative feeding and anti-collision mechanism 8 at the bottom of the worktable 1 collects the cut workpiece in a centralized manner to prevent it from falling and being damaged. This equipment achieves efficient and precise cutting and workpiece protection through multi-dimensional moving cutting, self-adaptive fixing and anti-collision collection, meeting diverse processing needs.

[0042] The collection box 81 is externally fixedly connected to the bottom of the workbench 1. A through-hole plate 82 is fixedly connected to the top of the collection box 81. This allows the cut workpieces to fall smoothly into the collection box 81 while also blocking larger scrap or incompletely cut workpieces, facilitating subsequent sorting. A connecting shaft 83 is rotatably connected inside the through-hole plate 82. When the cut workpiece falls into the collection box 81 through the through-hole of the through-hole plate 82, the quantitative baffle 84 rotates slowly under the drive of the connecting shaft 83. Each rotation at a certain angle allows a certain number of workpieces to pass through the gaps between the quantitative baffles 84 and enter the lower part of the collection box 81, achieving quantitative feeding of the workpieces and preventing a large number of workpieces from accumulating instantly and causing mutual interference. Collision and compression are prevented, thus protecting the appearance and precision of the workpiece. Multiple quantitative baffles 84 are fixedly connected to the outside of the connecting shaft 83. A telescopic rod 86 is fixedly connected to the bottom of the collection box 81. When the workpiece falls into the bottom of the collection box 81, it will first contact the top of the telescopic rod 86. The telescopic rod 86 will retract downward under the action of the workpiece's gravity. At the same time, the mounting spring 87 is compressed. The spring force will have a buffering effect on the workpiece, further reducing the impact force when the workpiece falls and preventing the workpiece from being damaged by collision. It plays a good role in preventing collision and providing protection. The telescopic rod 86 is fitted with a mounting spring 87. When the workpiece is removed, the mounting spring 87 will return to its original state, pushing the telescopic rod 86 to extend to the initial position, waiting for the next batch of workpieces to fall in.

[0043] Specifically, the bottom collection box 81 of the workbench 1 collects the cut workpieces, and the top through-hole plate 82 allows the workpieces to pass through while blocking large pieces of waste. The connecting shaft 83 inside the through-hole plate 82 drives multiple quantitative baffles 84 to rotate. Each rotation allows a certain number of workpieces to pass through the gaps and enter the box, avoiding accumulation and collision. The bottom telescopic rod 86 of the collection box 81 is fitted with a spring 87. When the workpiece falls, it squeezes the telescopic rod 86 to retract it. The spring buffers the impact and prevents bumps. After the workpiece is removed, the spring pushes the telescopic rod 86 to reset, waiting for the next batch of workpieces. This mechanism achieves safe collection of workpieces through quantitative feeding and elastic buffering, protecting their appearance and precision.

[0044] Reference Figures 2 to 3The adaptive fixing mechanism 7 includes a mounting frame 71, which has a frame structure with high structural strength. The mounting frame 71 is externally fixed to the outside of the fixing plate 9. Support rods 74 are fixedly connected to the top front and rear sides of the mounting frame 71, providing sliding guidance for the sliding pressure rod 75. This ensures that the sliding pressure rod 75 can slide smoothly and steadily up and down along the axial direction of the support rod 74, thereby realizing the clamping operation of workpieces of different thicknesses. The sliding pressure rod 75 is slidably connected to the outside of the support rod 74. The sliding pressure rod 75 can move freely up and down along the support rod 74, adjusting the distance between itself and the workpiece surface through its own up and down movement, thereby realizing the clamping or loosening of the workpiece. The outer middle part is fixedly connected to a limiting elastic component 76. The limiting elastic component 76 includes a mounting housing 761, which provides installation space for other components of the limiting elastic component 76. The mounting housing 761 is internally connected to a limiting plate 762, which restricts the position of the sliding pressure rod 75, preventing the sliding pressure rod 75 from exceeding the preset range during sliding, and can also transmit pressure to ensure the normal operation of the elastic component 76. The outside of the pressing rod 77 is fitted with a return spring 763. The return spring 763 can be compressed or stretched. When the external force disappears, the return spring 763 can restore its original shape by its own elasticity, driving the pressing rod 77 back to the initial position, thereby realizing the automatic reset of the component.

[0045] Specifically, the mounting bracket 71 is fixed to the fixing plate 9, and its top front and rear support rods 74 provide guidance for the sliding pressure rod 75. The sliding pressure rod 75 rises and falls along the support rods 74, adjusting the distance from the workpiece to achieve pressing or releasing. In the limiting spring assembly 76 at the middle end of the sliding pressure rod 75, the limiting plate 762 inside the mounting housing 761 restricts the sliding range, and the external return spring 763 of the extrusion rod 77 contracts when compressed and resets after the external force disappears, driving the extrusion rod 77 to reset, ensuring that the sliding pressure rod 75 applies pressure stably, adapting to workpieces of different thicknesses and ensuring the stability of the workpiece during cutting.

[0046] An extrusion rod 77 is slidably connected inside the sliding pressure rod 75. The extrusion rod 77 can slide freely along the axial direction inside the sliding pressure rod 75. It is an important component for transmitting pressure. When the sliding pressure rod 75 moves downward, it pushes the extrusion rod 77 to move downward synchronously, thereby transmitting the pressure to the mounting bracket 78 below. The bottom of the extrusion rod 77 is fixedly connected to the mounting bracket 78, which is used to install and fix the extrusion rollers 79, evenly distributing the pressure transmitted by the extrusion rod 77 onto the two extrusion rollers 79, while ensuring that the extrusion rollers 79 can stably contact the workpiece surface. The outer left and right sides of the mounting bracket 78 Each component is fixedly connected with an extrusion roller 79. When the extrusion roller 79 contacts the workpiece surface, the rubber material increases the friction between the roller and the workpiece, improving the fixing effect and preventing scratches on the workpiece surface. Support plates 72 are fixedly connected to the top front and rear sides of the mounting bracket 71. Two auxiliary rollers 73 are rotatably connected inside the support plate 72. The auxiliary rollers 73 can limit the left and right position of the workpiece, preventing the workpiece from shifting left and right during the cutting process. At the same time, when the workpiece is placed or moved, the rotation of the auxiliary rollers 73 can reduce the friction between the workpiece and the support plate 72, making the adjustment of the workpiece smoother.

[0047] Specifically, the extrusion rod 77, which is slidably connected inside the sliding pressure rod 75, moves downwards and transmits pressure to the bottom mounting bracket 78. The rubber extrusion wheels 79 on both sides of the bracket are evenly stressed and contact the workpiece, increasing friction and preventing scratches. The two auxiliary wheels 73 inside the top support plate 72 of the mounting bracket 71 not only limit the left and right position of the workpiece to prevent displacement, but also reduce friction through rotation and facilitate workpiece adjustment. Combined with the original structure, the sliding pressure rod 75 rises and falls along the support rod 74, and works with the limiting elastic component to apply stable pressure, achieving adaptive fixation of workpieces of different thicknesses and ensuring cutting accuracy.

[0048] Reference Figures 2 to 4The worktable 1 is externally slidably connected to a sliding guide rail 2. The sliding guide rail 2 is a high-precision linear guide rail, consisting of a guide rail body and a slider. The guide rail body is fixed to the outer edge of the worktable 1 by bolts, and its length matches the length of the worktable 1. A hydraulic cylinder 3 is fixedly connected to the top of the sliding guide rail 2. Its main function is to provide strong driving force. Through the control of the hydraulic system, the piston rod can perform telescopic movement, thereby driving the components connected to the piston rod to achieve vertical or horizontal displacement. It has a large driving force, smooth operation, and strong controllability, and can provide stable power support for the movement of the sliding block 4. The sliding block 4 is externally fixedly connected to the drive end of the hydraulic cylinder 3. A rubber plate 85 is fixedly connected to the top of the telescopic rod 86. The rubber plate 85 is made of high-elasticity wear-resistant rubber. The shape matches the internal cross-section of the collection box 81, and the size is slightly smaller than the internal size of the collection box 81. The rubber plate 85 is externally slidably connected to the inside of the collection box 81. This not only does not affect the up and down movement of the rubber plate 85 with the telescopic rod 86, but also provides a certain limiting effect on the workpiece, preventing the workpiece from falling from the gap between the rubber plate 85 and the inner wall of the collection box 81 to the bottom of the collection box 81, ensuring that all workpieces can be supported by the rubber plate 85 and fully exert its buffering and protective function. The limiting plate 762 is externally fixedly connected to the inside of the extrusion rod 77. The external top end of the mounting bracket 78 contacts the external bottom end of the sliding pressure rod 75. One end of the return spring 763 is fixedly connected to the external top end of the mounting bracket 78, and the other end of the return spring 763 is fixedly connected to the external bottom end of the limiting plate 762.

[0049] Specifically, the outer sliding guide rail 2 of the worktable 1 supports the hydraulic cylinder 3, whose drive end is connected to the sliding block 4. The sliding block 4 moves smoothly through hydraulic drive. The sliding block 4 drives the electric guide rail 5 and the laser cutting head 6 to adjust their positions. It works in conjunction with the adaptive fixing mechanism 7 to fix the workpiece. During fixing, the sliding pressure rod 75 drives the extrusion rod 77 to apply pressure, the return spring 763 buffers the pressure, and the extrusion wheel 79 and the auxiliary wheel 73 work together to limit the movement. During unloading, the rubber plate 85 inside the collection box 81, together with the telescopic rod 86 and the mounting spring 87, buffers the impact of the falling workpiece. The quantitative baffle 84 controls the unloading amount, achieving precise cutting and workpiece protection.

[0050] The implementation principle of this application embodiment is as follows:

[0051] By placing the steel pipe outside the support plate 72 and pushing it inward, the extrusion roller 79 can extrude the extrusion rod 77 through the mounting bracket 78. This causes the return spring 763 outside the extrusion rod 77 to deform, allowing the steel pipe to be stably fixed by the force of the return spring 763. Because the support plate 72 is equipped with an auxiliary wheel 73, when the steel pipe is rotated to adjust the cutting position and the cutting of the steel pipe is stopped, the return spring 763 automatically rebounds by removing the steel pipe, allowing the extrusion roller 79 to contact the auxiliary wheel 73.

[0052] After the steel pipe is cut, it falls and the force of the falling pipe causes the metering baffle 84 to rotate. The metering baffle 84 then causes the steel pipe to fall into the collection box 81, where it comes into contact with the rubber plate 85. The rubber plate 85 then compresses the telescopic rod 86, causing the external spring 87 of the telescopic rod 86 to deform. This allows for the metering of the steel pipe and prevents it from falling off and causing damage during the fall.

[0053] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
