Description

Technical Field

[0001] This invention belongs to the field of laser cutting technology. Specifically, this invention relates to a multi-station high-power dual-laser cutting production line. Background Technology

[0002] Laser cutting uses a high-energy-density laser beam to heat the workpiece, causing the temperature to rise rapidly and reach the boiling point of the material in a very short time. The material begins to vaporize, forming vapor and creating a cut in the material. It has advantages such as high cutting precision, fast cutting speed, smooth cutting surface, and less damage to the workpiece. In particular, it reduces the cost of subsequent processing. Its advantages are especially obvious in mass production, so it has gained increasing recognition and application from more and more industries and enterprises.

[0003] However, existing laser cutting methods have the following drawbacks:

[0004] Existing laser cutting machines cannot process a width of more than 5 meters and the exchange table length is less than 15 meters, which cannot meet the ultra-large sheet metal cutting requirements of steel mills or large equipment manufacturers.

[0005] Traditional manual feeding has the following problems: low efficiency, poor feeding accuracy, and certain dangers. Improper operation may lead to major safety accidents. Summary of the Invention

[0006] This invention provides a multi-station high-power dual-laser cutting production line, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a multi-station high-power dual laser cutting production line, including a ground rail and a material unloading trolley and a finished product trolley that are slidably set on the ground rail, and a first cutting station, a material transfer station and a second cutting station are arranged sequentially along the length direction of the ground rail;

[0008] The first cutting station is equipped with an ultra-large format cutting mechanism for cutting ultra-large format materials; the material transfer station is equipped with a loading and unloading mechanism for loading and unloading materials at the first and second cutting stations; the second cutting station is equipped with a conventional format cutting mechanism for cutting conventional format materials.

[0009] The ultra-large format cutting mechanism consists of a loading and unloading area and a cutting area. It includes a high table bed assembly set in the cutting area, an outer cover for protecting the high table bed assembly from being affected during cutting, a low table bed assembly set in the loading and unloading area, and a cutting assembly slidably set on the high table bed assembly.

[0010] The loading and unloading mechanism includes an x-axis motion component located on the ground and moving along the length of the ground rail, a Y-axis motion component mounted on the x-axis motion component and moving along the Y-axis direction of the x-axis motion component, a Z-axis motion component mounted on the Y-axis motion component and moving along the Z-axis direction of the Y-axis motion component, a suction cup loading component mounted on the bottom of the Z-axis motion component, and a telescopically mounted insertion rod unloading component mounted on the suction cup loading component.

[0011] Preferably, the high-table bed assembly includes a ground rail bed, an upper cutting table disposed on the ground rail bed, a support roller a disposed below the upper cutting table, a cycloidal pinwheel reducer motor a for driving the upper cutting table, and a pneumatic support a installed below the center of the upper cutting table.

[0012] Preferably, the low-table bed assembly includes a lower cutting table that is lower than the horizontal plane of the upper cutting table, a support roller b disposed below the lower cutting table, a cycloidal pinwheel reducer motor b for driving the lower cutting table, and a pneumatic support b installed in the lower middle part of the lower cutting table.

[0013] Preferably, the cutting assembly includes a movable gantry that is slidably mounted on the ground rail bed and a laser cutting head mounted on the movable gantry.

[0014] Preferably, the x-axis motion assembly includes two side frames, rollers mounted below the side frames, a connecting rod for connecting the two side frames, and a reinforcing rod for enhancing structural strength.

[0015] Preferably, the Y-axis motion assembly includes two slide bars mounted between two side frames and a slide plate slidably connected to the slide bars.

[0016] Preferably, the Z-axis motion assembly includes a lifting cylinder mounted on the slide plate and a lifting column connected to the output end of the lifting cylinder.

[0017] Preferably, the suction cup feeding assembly includes a mounting frame fixedly connected to the bottom of the lifting column and several groups of suction cups evenly arranged below the mounting frame.

[0018] Preferably, the insert rod feeding assembly includes tension rods symmetrically arranged on both sides of the mounting frame, a long rod installed below the tension rods, and several sets of insert rods evenly arranged at the bottom of the long rods.

[0019] Preferably, both the extra-large format cutting mechanism and the conventional format cutting mechanism are equipped with auxiliary mechanisms, which include a storage rack on the ground and a voltage stabilizer, a water chiller and a power distribution box respectively installed on the storage rack.

[0020] The beneficial effects of adopting the above technical solutions are:

[0021] First, the first cutting station, the material transfer station, and the second cutting station can achieve fully automated production. This can meet the cutting requirements of ultra-large format plates needed by steel mills or large equipment manufacturers, as well as conventional format plates, reducing machine operating costs and increasing machine production efficiency.

[0022] Second, in addition to producing ultra-large format panels, the ultra-large format cutting mechanism also has the advantages of low energy consumption, high processing precision, and high efficiency. Moreover, the cutting process generates low levels of harmful gases, and the exhaust gas can fully meet the emission standards required by environmental protection after treatment. The frame-type large enclosure has high strength and strong sealing performance, which has a good isolation effect on the noise and harmful gases generated during processing. In addition, it can also realize that while one cutting table is cutting, another cutting table is loading and unloading, which greatly shortens the processing time required for the panels.

[0023] Third, the loading and unloading mechanism automatically feeds the two sets of cutting machines. On the one hand, it solves the problems of low efficiency, poor accuracy and certain dangers of manual feeding, and the possibility of major safety accidents if the operation is not done properly. On the other hand, the horizontal arrangement of the cutting line is convenient for equipment placement and operator management, maximizes the use of space, facilitates loading and unloading, and greatly improves the working efficiency of the machine.

Detailed Implementation

[0041] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and to facilitate its implementation. Example 1

[0042] Specifically, such as Figures 1 to 15As shown, a multi-station high-power dual laser cutting production line includes a ground rail 100 and a material unloading 200 and a finished product trolley 300 slidably disposed on the ground rail 100. A first cutting station, a material transfer station and a second cutting station are arranged sequentially along the length direction of the ground rail 100.

[0043] It should be noted that the conveyor line uses a rail-guided flatbed cart mode, which is stable and safe. The flatbed carts are used for fixed-point loading and unloading, with raw material points, loading point 1, loading point 2, loading point 3, ... unloading point 1, unloading point 2, unloading point 3, ... sorting point 1, sorting point 2, sorting point 3, ... achieving efficient and stable operation of the entire cutting line.

[0044] The first cutting station is equipped with an ultra-large format cutting mechanism 1 for cutting ultra-large format materials; the material transfer station is equipped with a loading and unloading mechanism 2 for loading and unloading materials at the first and second cutting stations; the second cutting station is equipped with a conventional format cutting mechanism 3 for cutting conventional format materials.

[0045] It should be noted that the extra-large format cutting mechanism 1 and the conventional format cutting mechanism 3 on the first and second cutting stations are arranged in a straight line with their tails facing each other. The moving area of ​​the loading and unloading mechanism 2 is the loading area at the tail of the extra-large format cutting mechanism 1 and the conventional format cutting mechanism 3. That is, when it is necessary to cut extra-large format materials, they are loaded and unloaded onto the extra-large format cutting mechanism 1 through the loading and unloading mechanism 2, while when it is necessary to cut normal format materials, they are loaded and unloaded onto the conventional format cutting mechanism 3 through the loading and unloading mechanism 2.

[0046] In addition, the conventional cutting mechanism 3 is a double-table parallel exchange laser cutting machine, which increases the cutting area compared to the conventional cutting machine, increasing the effective cutting area to 12.5 meters x 2 meters. The double-table parallel exchange laser cutting machine is existing technology and will not be described in detail here. The conventional cutting mechanism 3 is simply an extension of it.

[0047] In detail, it should be noted that the loading and unloading mechanism 2, the incoming material unloading car 200 and the finished product trolley 300 work together with the ground rail 100 to complete the loading and unloading work, eliminating the traditional manual loading or low-power single loading mechanism. This solves the problems of low efficiency, poor loading accuracy and certain dangers of manual loading, and the possibility of major safety accidents if the operation is not done properly.

[0048] The ultra-large format cutting mechanism 1 consists of a loading and unloading area and a cutting area, including a high table bed assembly 11 set in the cutting area, an outer cover 12 for protecting the high table bed assembly 11 from being affected during cutting, a low table bed assembly 13 set in the loading and unloading area, and a cutting assembly 14 slidably set on the high table bed assembly 11.

[0049] It should be noted that the high-platform bed assembly 11 and the low-platform bed assembly 13 break away from the traditional bed design of separate structures, so that neither of them will affect the other during the working process.

[0050] The high-platform bed assembly 11 includes a ground rail bed 111, an upper cutting table 112 disposed on the ground rail bed 111, a support roller a113 disposed below the upper cutting table 112, a cycloidal pinwheel reducer motor a114 for driving the upper cutting table 112, and a pneumatic support a115 installed below the middle of the upper cutting table 112.

[0051] It should be noted that the support roller a113 under the upper cutting table 112 is fixed to the ground to avoid vibration of the high table bed assembly 11 during movement, which would affect the accuracy. The upper cutting table 112 is driven by a cycloidal pinwheel reducer motor a114 with a friction wheel. The upper cutting table 112 moves forward and backward by the forward and reverse rotation of the friction wheel. Since all drives are separate and the upper and lower frames are completely separated, their movements have no effect on each other.

[0052] In addition, due to the excessive length in the width direction, in order to prevent the cutting table from sagging in the middle due to its own weight, the excessive weight of the plate being loaded, and the heat during the cutting process, a central cylinder pneumatic support was added to ensure the service life of the cutting table. The support is divided into two types: upper frame support and lower frame support.

[0053] In detail, the bed is an assembled bed, consisting of two side wall panels, transverse support components, and high-strength aluminum crossbeams. The assembled bed is easy to process and has high strength, which can ensure the accuracy of equipment operation.

[0054] The low-table bed assembly 13 includes a lower cutting table 131 that is lower than the horizontal plane of the upper cutting table 112, a support roller b132 disposed below the lower cutting table 131, a cycloidal pinwheel reducer motor b133 for driving the lower cutting table 131, and a pneumatic support component b134 installed below the middle of the lower cutting table 131.

[0055] It should be noted that the low-table bed assembly 13 operates in the same way as the high-table bed assembly 11 described above.

[0056] The cutting assembly 14 includes a movable gantry 141 slidably mounted on the ground rail bed 111 and a laser cutting head 142 mounted on the movable gantry 141.

[0057] It should be noted that the cutting of the sheet material is performed using the laser cutting head 142.

[0058] Both the extra-large format cutting mechanism 1 and the conventional format cutting mechanism 3 are equipped with auxiliary mechanisms 4, which include a storage rack 41 set on the ground and a voltage stabilizer 42, a water chiller 43 and a power distribution box 44 respectively set on the storage rack 41. Example 2

[0059] Specifically, such as Figures 1 to 10 As shown, the loading and unloading mechanism 2 includes an x-axis motion component 21 located on the ground and moving along the length of the ground rail 100, a Y-axis motion component 22 mounted on the x-axis motion component 21 and moving along the Y-axis direction of the x-axis motion component 21, a Z-axis motion component 23 mounted on the Y-axis motion component 22 and moving along the Z-axis direction of the Y-axis motion component 22, a suction cup loading component 24 mounted on the bottom of the Z-axis motion component 23, and a telescopically mounted insertion rod unloading component 25 mounted on the suction cup loading component 24.

[0060] It should be noted that the suction cup loading component 24 and the insertion rod unloading component 25 are adjusted in lateral position by the x-axis motion component 21, in longitudinal position by the Y-axis motion component 22, and in height position by the Z-axis motion component 23, respectively, so as to flexibly load and unload materials at different positions.

[0061] The x-axis motion assembly 21 includes two side frames 211, rollers 212 mounted below the side frames 211, a connecting rod 213 for connecting the two side frames 211, and a reinforcing rod 214 for enhancing structural strength.

[0062] It should be noted that the x-axis motion component 21 is adjusted by moving and adjusting the roller 212 and the guide rail adapted to the roller 212.

[0063] The Y-axis motion assembly 22 includes two slide bars 221 mounted between two side frames 211 and a slide plate 222 slidably connected to the slide bars 221.

[0064] It should be noted that the Y-axis motion component 22 is adjusted by moving the sliding plate 222. The driving source for this operation is not limited and can be any type of drive such as a cylinder, servo motor, or lead screw.

[0065] The Z-axis motion assembly 23 includes a lifting cylinder 231 mounted on a sliding plate 222 and a lifting column 232 connected to the output end of the lifting cylinder 231.

[0066] It should be noted that the Z-axis motion component 23 is adjusted by the lifting cylinder 231 driving the lifting column 232 to move up and down.

[0067] The suction cup feeding assembly 24 includes a mounting frame 241 fixedly connected to the bottom of the lifting column 232 and several groups of suction cups 242 evenly arranged below the mounting frame 241.

[0068] It should be noted that the raw material boards are regular whole boards and the raw materials are stacked in multiple sheets, so using the suction cup feeding component 24 is convenient, economical and can achieve the function of separating the sheets.

[0069] The insert rod feeding assembly 25 includes tension rods 251 symmetrically arranged on both sides of the mounting frame 241, long rods 252 installed below the tension rods 251, and several sets of insert rods 253 evenly arranged at the bottom of the long rods 252.

[0070] It should be noted that the board is shredded after cutting, so the insert feeding assembly 25 is used.

[0071] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other situations without modification, are all within the protection scope of the present invention.
