Description

Technical Field

[0001] The present application relates to the field of laser cutting technology, and in particular to a floor-rail laser cutting machine. Background Art

[0002] In modern industrial manufacturing, sheet metal laser cutting technology, with its significant advantages such as high precision, high speed, and non-contact processing, has become a key tool for sheet metal processing. Laser cutting utilizes a high-energy-density laser beam to instantly melt and vaporize the sheet metal, achieving the desired effect. This cutting method can meet the needs of cutting a wide range of complex shapes and is widely used in numerous industries, including automotive, aerospace, and machining.

[0003] However, existing laser cutting systems present several pressing challenges. Most common laser cutting systems on the market are equipped with only a single platform. When cutting a sheet, the sheet must be precisely positioned on this single platform before the cutting process can begin. This process is not only cumbersome but also requires significant time to load and position a new sheet after each cut. This significantly reduces overall cutting efficiency and fails to meet the demands of large-scale, high-efficiency production.

[0004] Furthermore, heat dissipation is a major shortcoming of existing laser cutting systems. During the laser cutting process, the interaction between the high-energy laser beam and the sheet metal generates a significant amount of heat. Due to the poor heat dissipation efficiency of existing systems, this heat cannot be dissipated promptly and effectively, resulting in a sharp increase in the local temperature of the sheet metal. Prolonged exposure to high temperatures can easily cause the sheet metal to deform, seriously affecting cutting accuracy and product quality. For industries with extremely high precision requirements, such as aerospace, high-temperature deformation of the sheet metal can cause the product to fail to meet design standards, resulting in significant economic losses.

[0005] In summary, the existing laser cutting devices have obvious deficiencies in efficiency and heat dissipation. There is an urgent need for a new type of ground-track laser cutting machine to solve these problems, so as to improve the efficiency and quality of plate cutting and meet the actual needs of industrial production.

[0037] The technical solutions in the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of the present invention, but are not limited thereto. Those skilled in the art can fully combine the embodiments of the present invention, and other embodiments obtained without creative work are also within the scope of protection of the present invention.

[0038] This application mainly adopts dual-platform switching cutting and targeted ventilation and heat dissipation solutions to improve the plate cutting efficiency and heat dissipation effect and avoid plate deformation. The following is a further detailed description of this application.

[0039] Example 1

[0040] Please refer to Figures 1-6The floor-rail laser cutting machine provided in the embodiment of the present application includes a supporting mechanism 1, a laser cutting mechanism 2 and a ventilation mechanism 3, wherein the supporting mechanism 1 is used to support the plate and realize dual-platform switching loading, the laser cutting mechanism 2 is used to cut the plate, and the ventilation mechanism 3 is used to specifically dissipate the heat generated by the cutting, thereby improving the cutting efficiency and heat dissipation effect and reducing the deformation of the plate.

[0041] For details, please refer to Figures 1-5 The supporting mechanism 1 includes a box body 11, a plurality of partitions 12, two sets of guide rails 13, two sliding platforms 14 and a translation drive member 15. The box body 11 has a accommodating cavity with an open upper end, which can be made of metal material, such as stainless steel, to ensure its durability. Each partition 12 is arranged in the accommodating cavity in a direction perpendicular to the guide rail 13. The partition 12 includes a first inclined plate 121 and a second inclined plate 122. The first inclined plate 121 and the second inclined plate 122 are arranged relative to each other at an angle, and the tops of the two are connected. This structure is like a roof shape, which makes it convenient for the debris or fragments generated during cutting to fall on the first inclined plate 121 and the second inclined plate 122. When they slide down to the middle part of the ventilation channel under the action of gravity, they are easily collected. The first inclined plate 121 of each partition 12 forms a ventilation channel with the adjacent second inclined plate 122. The partition 12 can also be replaced by a triangular plate, as long as a ventilation channel can be formed. Through such separation, air can selectively flow in specific ventilation channels, thereby improving ventilation and heat dissipation effects.

[0042] Please refer to Figures 1-5The two sets of guide rails 13 are arranged in parallel with a height difference. This arrangement allows the two sliding platforms 14 to operate at different heights to avoid mutual interference. One end of each set of guide rails 13 is fixed to the box body 11 and is mounted above the accommodating cavity, and the other end extends to the side of the box body 11. A number of rollers 141 are arranged around the sliding platform 14. The rollers 141 are slidably arranged on the corresponding guide rails 13. The rollers 141 can be made of polyurethane to reduce friction and improve the smoothness of sliding. Of course, sliders can also be used instead of rollers 141. The translation drive member 15 includes two driving sprockets 151, two driven sprockets, two chains 152, a driving shaft 153 and a driving motor 154. The two driving sprockets 151 are respectively rotatably set at one end of the two guide rails 13, and the two driven sprockets are respectively rotatably set at the other end of the two guide rails 13. One end of the two chains 152 is respectively wound around the two driving sprockets 151, at least one node of the upper part of the two chains 152 is fixedly connected to the two sides of a sliding platform 14, and at least one node of the lower part of the two chains 152 is fixedly connected to the two sides of another sliding platform 14. The other ends of the two chains 152 are respectively wound around the two driven sprockets, the driving shaft 153 is transmission-connected to the two driving sprockets 151, and the driving motor 154 is connected to the driving shaft 153 and is used to drive the driving shaft 153 to rotate. With this structure, the drive motor 154 drives the drive shaft 153 to rotate, which in turn drives the driving sprocket 151 to rotate, causing the chain 152 to move. Because the two sliding platforms 14 are respectively fixed to the upper and lower parts of the chain 152, and the upper and lower parts move in opposite directions when the chain 152 rotates, the two sliding platforms 14 can move simultaneously in opposite directions. When one sliding platform 14 reaches the top of the accommodating cavity, the other can just reach the side of the accommodating cavity, facilitating material loading.

[0043] Please refer to Figures 1-5 The support mechanism 1 further includes a plurality of drawer boxes 16 corresponding to each ventilation channel. The drawer boxes 16 are slidably disposed within the housing 11 and can be withdrawn along the side of the housing 11. A pull-out handle 161 is fixed to the sidewall of each drawer box 16. The drawer boxes 16 can be made of plastic to reduce weight. When cutting generates debris or chips that fall into the ventilation channels, the first and second inclined plates 121, 122 prevent the chips or chips from falling into the drawer boxes 16. The drawer boxes 16 can be withdrawn for cleaning.

[0044] For details, please refer to Figure 2 、 Figure 3 、 Figure 8 and Figure 9The laser cutting mechanism 2 includes a transverse drive 21 and a laser cutting assembly 22. The transverse drive 21 includes two transverse rails 211, two mobile trolleys 212, and a crossbeam 213. The two transverse rails 211 are respectively fixed to the two sides of the box 11 and are located above the guide rail 13. The two mobile trolleys 212 can move along the corresponding transverse rails 211. The ends of the crossbeam 213 are respectively fixed to the two mobile trolleys 212. The laser cutting assembly 22 is mounted on the crossbeam 213. The mobile trolley 212 can be electrically driven, and the wheels are driven by the motor to move on the transverse rails 211. The laser cutting assembly 22 includes a linear motor 221, a lifting drive 222, a rotary motor 223, and a laser emitter 224. The linear motor 221 is fixed to the beam 213 and connected to the lifting drive 222 to drive it to move along the length of the beam 213. The movable end of the lifting drive 222 is connected to the fixed end of the rotary motor 223 and is used to drive the rotary motor 223 to move up and down. The rotary motor 223 is connected to the laser emitter 224 and is used to drive the laser emitter 224 to rotate. The linear motor 221 can accurately control the lateral position of the laser cutting assembly 22, the lifting drive 222 can adjust the height of the laser emitter 224, and the rotary motor 223 can change the angle of the laser emitter 224, thereby achieving cutting at different angles and positions.

[0045] For details, please refer to Figures 2-6 The ventilation mechanism 3 includes a control component and a ventilation assembly. A side wall of the box body 11 is provided with a plurality of air inlets 111 connected to one end of each ventilation channel, and the other opposite side wall of the box body 11 is provided with a plurality of air outlets 112 connected to the other end of each ventilation channel. The ventilation assembly includes a plurality of ventilation valves 31, a blower 32 and an air outlet pipe 33. Each ventilation valve 31 is respectively installed on the corresponding air inlet 111. The outlet of the blower 32 is connected to one end of the air outlet pipe 33, and the air outlet pipe 33 is connected to each ventilation valve 31. The control component is in communication with the transverse driving component 21 and the ventilation assembly, and is used to ventilate the ventilation assembly into the ventilation channel below the laser cutting assembly 22 according to the position of the movable end of the transverse driving component 21. In this way, ventilation is only conducted into the ventilation channel below the current laser cutting assembly 22, so that the air discharged by the blower 32 can enter the ventilation channel below the current laser cutting assembly 22 for ventilation, thereby improving the ventilation and heat dissipation effect.

[0046] Please refer to Figure 1 The ground rail laser cutting machine also includes a protective cover 4, which is arranged outside the box 11 and the laser cutting mechanism 2. The protective cover 4 can be provided with a transparent window to facilitate the operator to observe the cutting situation.

[0047] The operating principle of this embodiment is as follows: During operation, the translational drive 15 causes the two sliding platforms 14 to move alternately, one performing cutting above the accommodating cavity and the other loading material to the side, saving loading time and improving cutting efficiency. The ventilation mechanism 3, based on the position of the laser cutting assembly 22, selectively ventilates the ventilation channel below the cutting area, effectively removing heat generated by cutting and reducing sheet material deformation due to high temperatures. Furthermore, the drawer box 16 facilitates the removal of cutting debris, keeping the equipment clean. The overall structural design is rational, enhancing the practicality and reliability of the equipment and providing a significant improvement and upgrade over existing technologies.

[0048] Example 2

[0049] Please refer to Figures 2-7 , the difference between this embodiment and the above embodiment is that: the ground rail type laser cutting machine also includes a cutting point cooling mechanism 5. A side wall of the box body 11 is also provided with a plurality of sockets connected to one end of each ventilation channel, and the sockets are located above the corresponding air inlet 111. The cutting point cooling mechanism 5 includes a plurality of inserts 51, a plurality of control valves 52, a plurality of rotary nozzles 53, a connecting pipe 54, a movable driving member 55, a liquid nitrogen tank 56, a liquid pump 57 and a connecting hose 58. Each insert 51 is slidably inserted into the corresponding ventilation channel, the input end of each control valve 52 is connected to one end of the corresponding insert 51, and the other end of each control valve 52 is connected to the corresponding rotary nozzle 53. The outlet of the rotary nozzle 53 is set upward, the connecting pipe 54 is connected to the other end of each insert 51, the movable driving member 55 is connected to the connecting pipe 54, and is used to drive the connecting pipe 54 to move along the length direction of the insert 51, and the inlet of the liquid pump 57 The port is connected to the outlet of the liquid nitrogen tank 56, and the outlet of the liquid pump 57 is connected to the connecting pipe 54 via the connecting hose 58. The control component is communicated with the transverse driving component 21, the laser cutting component 22 and the ventilation component, and is used to determine the position of the current cutting point according to the transverse driving component 21 and the laser cutting component 22, and determine the longitudinal position of each rotating nozzle 53 according to the position of the current cutting point, so that the longitudinal position of each rotating nozzle 53 is the same as the longitudinal position of the cutting point, and the control valve 52 closest to the cutting point is opened, and the coverage range of the sprayed liquid of the rotating nozzle 53 is within the preset range around the cutting point by adjusting the rotation angle of the rotating nozzle 53.

[0050] The operating principle of this embodiment is as follows: During the cutting process, in addition to the heat dissipation by the ventilation mechanism 3, the cutting point cooling mechanism 5 can directly cool the area surrounding the cutting point of the sheet. The specific process is as follows: The control unit communicates with the transverse drive 21 and the laser cutting assembly 22, and determines the current cutting point position based on the status of the transverse drive 21 and the laser cutting assembly 22. Based on the determined cutting point position, the control unit activates the mobile drive 55, which drives the connecting tube 54 to move along the length of the insert 51, so that the longitudinal position of each rotating nozzle 53 is the same as the longitudinal position of the cutting point (in this application, the direction parallel to the guide rail 13 is defined as the transverse position, and the horizontal direction perpendicular to the guide rail 13 is defined as the longitudinal position). The control unit locates the control valve 52 closest to the cutting point and opens it, allowing liquid nitrogen to be sprayed from the corresponding rotating nozzle 53. By adjusting the rotation angle of the rotating nozzle 53, the coverage area of ​​the liquid nitrogen sprayed by the rotating nozzle 53 is within a preset range around the cutting point, achieving precise cooling of the area surrounding the cutting point.

[0051] The specific rotation angle of the rotating nozzle 53 can be determined by the following method:

[0052] (1) Establish a coordinate system: Establish a plane rectangular coordinate system based on the cutting platform, and determine the coordinates of the cutting point in the coordinate system (x0, y0). At the same time, obtain the current position coordinates of the rotating nozzle (x1, y1).

[0053] (2) Determine the preset range: According to the cutting process requirements, determine the preset range that needs to be cooled around the cutting point. It can usually be represented by a circular area with a radius of r and the cutting point as the center.

[0054] (3) Calculate the angle range: Calculate the starting angle of the rotating nozzle 53 that needs to cover the preset range through trigonometric functions α 1 and end angle α 2. Assume that the line connecting the rotating nozzle 53 to the cutting point is x The angle in the positive direction of the axis is θ ,but: ,

[0055] According to the radius of the preset range r And the distance from the rotating nozzle 53 to the cutting point: ,

[0056] The angular offset Δ required to cover the preset range can be calculated α , and then get the starting angle α 1= θ −Δ α and end angle α 2= θ +Δ α .

[0057] In this embodiment, a large amount of heat is generated during the laser cutting process, and relying solely on the ventilation mechanism 3 to dissipate heat has certain limitations. Liquid nitrogen tank 56, serving as a storage container for the cooling medium, stores low-temperature liquid nitrogen, providing a foundation for cooling the cutting point. Liquid pump 57 extracts liquid nitrogen from liquid nitrogen tank 56 and delivers it to connecting pipe 54 via connecting hose 58. Connecting pipe 54 distributes the liquid nitrogen, evenly distributing it to each cannula 51. Each cannula 51 is slidably inserted into its corresponding ventilation channel, directing the liquid nitrogen to the vicinity of the cutting point. Control valve 52 controls the flow of liquid nitrogen. Only the control valve 52 closest to the cutting point is opened, ensuring that the liquid nitrogen is precisely delivered to the location requiring cooling. Rotating nozzle 53 sprays liquid nitrogen over a defined coverage area, with its outlet facing upward, enabling it to directly affect the area surrounding the cutting point. Through the coordinated operation of this series of components, the cutting point cooling mechanism 5 can directly cool the area surrounding the cutting point of the sheet metal. Working in conjunction with the ventilation mechanism 3, this further improves heat dissipation efficiency and more effectively removes the heat generated by cutting. Since the cutting point cooling mechanism 5 can timely cool down the area around the cutting point, the local temperature of the plate is reduced, and the plate is prevented from being in a high temperature state for a long time, thereby greatly reducing the deformation of the plate caused by high temperature. The mobile drive member 55 is connected to the connecting tube 54, and can drive the connecting tube 54 to move along the length direction of the insert 51 to adapt to the change in the position of the cutting point. This allows the rotating nozzle 53 to always accurately align with the cutting point, ensuring that liquid nitrogen is continuously and accurately sprayed around the cutting point. For some industries with extremely high precision requirements, such as the aerospace field, this technical effect can ensure that the cut plate meets the design standards and improve the quality and yield rate of the product.

[0058] The technical effects of the technical solution provided by this application include:

[0059] (1) During operation, the translation drive 15 causes the two sliding platforms 14 to move alternately, one for cutting above the accommodating cavity and the other for loading materials on the side, which saves loading time and improves cutting efficiency. The ventilation mechanism 3 ventilates the ventilation channel below the cutting surface in a targeted manner according to the position of the laser cutting component 22, effectively removing the heat generated by the cutting and reducing the deformation of the plate due to high temperature;

[0060] (2) The drawer box 16 is convenient for cleaning the debris generated by cutting and keeping the equipment clean;

[0061] (3) The position and opening of the rotating nozzle 53 are precisely controlled by the control unit, so that the liquid nitrogen is accurately sprayed around the cutting point, and works in conjunction with the ventilation mechanism 3 to further improve the heat dissipation efficiency and more effectively remove the heat generated by cutting.

[0062] The specific implementation methods of the present application described above do not constitute a limitation on the scope of protection of the present application. Any other corresponding changes and modifications made based on the technical concept of the present application should be included in the scope of protection of the present application.
