Description

Technical Field

[0001] The present invention belongs to the technical field of sheet metal processing, and specifically relates to a three-dimensional five-axis laser cutting device for sheet metal processing. Background Art

[0002] As a high-quality, high-precision, and high-efficiency processing method, laser cutting technology has been widely used in fields such as aviation, aerospace, and automobile manufacturing. Existing laser cutting systems can be applied to the processing of flat workpieces such as sheet metal parts, profiles, and fabrics. When processing sheet metal parts, feeding is required.

[0003] Some technical solutions have also been proposed for the feeding of sheet metal parts in the prior art. For example, the patent with the publication number CN102500931A discloses an automatic loading and unloading laser cutting machine, which includes a hopper. A calibration mechanism for aligning multiple sheet materials is provided on one side of the hopper, and a gap adjustment mechanism for allowing one sheet material to pass through is provided on the other side of the hopper. After multiple sheet materials are placed in the hopper, the calibration mechanism aligns the multiple sheet materials, and then the gap adjustment mechanism leaves a passage for one sheet material to pass through. Then, the feeding mechanism drives the sheet material to slide out of the hopper and move to the cutting table.

[0004] The above technical solution solves the problem of difficult feeding by stacking sheet metal parts together and pushing out the bottom sheet metal part one by one. However, there are still some problems in the feeding process: for example, stacking sheet metal parts together causes a large gravity on the bottom when pushing, which is not convenient for pushing out the sheet metal parts; and when stacking sheet metal parts together and pushing them out, the friction between the sheet metal parts is large, and it is easy to cause scratches on the surfaces of adjacent sheet metal parts.

[0005] Therefore, the present invention provides a three-dimensional five-axis laser cutting device for sheet metal processing. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A three-dimensional five-axis laser cutting device for sheet metal processing according to the present invention includes a workbench; a three-dimensional five-axis laser cutting seat is fixedly installed on the upper surface of the workbench, and the three-dimensional five-axis laser cutting seat is used for cutting sheet metal parts, and it can rotate arbitrarily on the X, Y, and Z axes. This is prior art and will not be elaborated further here; a support plate is fixedly installed on the upper surface of the workbench on the side away from the three-dimensional five-axis laser cutting seat; a first placement plate and a second placement plate are fixedly installed on the upper surface of the support plate; the first placement plate and the second placement plate are arranged at intervals; a plurality of partition plates for placing sheet metal parts are arranged on the surface of the first placement plate, and the plurality of partition plates are arranged at equal distances; a pushing mechanism is arranged on the upper surface of the support plate near the first placement plate side, and the pushing mechanism is used for intermittently pushing different sheet metal parts.

[0008] During normal use, the sheet metal parts are placed on the surfaces of the partition plates at different positions, so that the sheet metal parts are arranged at intervals from top to bottom. By operating the three-dimensional five-axis laser cutting seat, the sheet metal parts on the surface of the workbench are cut in any direction on the X, Y, and Z axes until the required shape of the sheet metal parts is achieved; when a sheet metal part is processed and it is necessary to load the sheet metal part, the pushing mechanism is driven to move by an external controller. The pushing mechanism pushes the lowermost sheet metal part towards the surface of the workbench, and then pushes it above the workbench for laser cutting treatment of the new sheet metal part. In the embodiment of the present invention, the sheet metal parts are arranged at intervals from top to bottom, which can more conveniently push out the lowermost sheet metal part. This not only avoids the problem that the sheet metal parts are stacked together, resulting in a large gravity on the bottom when pushed, making it inconvenient to push out the sheet metal parts; but also solves the problem that when the sheet metal parts are stacked together and pushed out, the sheet metal parts rub against each other, easily causing scratches on the surface of the sheet metal parts; at the same time, since a small amount of dust is generated during laser cutting, the embodiment of the present invention also avoids the problem that manual loading causes dust inhalation by the staff, affecting their health.

[0009] Preferably, the pushing mechanism includes a telescopic cylinder fixedly connected to the upper surface of the support plate; a first toothed plate is fixedly connected to the telescopic end of the telescopic cylinder; a feeding plate is fixedly installed on the side of the first toothed plate away from the telescopic cylinder; two connecting frames are fixedly installed on the upper surface of the support plate near the first toothed plate side; a central gear is rotatably connected between the two connecting frames; a linkage frame is fixedly installed on the surface of the lowermost partition plate; a second toothed plate is arranged on the side of the linkage frame close to the central gear; the central gear is meshed with the second toothed plate and the first toothed plate respectively.

[0010] During operation, when a new sheet metal part needs to be ejected, the telescopic end of the telescopic cylinder is controlled to move. The telescopic end drives the first toothed plate and the feeding plate to move towards the side close to the first placing plate. Since the first toothed plate meshes with the central gear, and the central gear meshes with the second toothed plate, when the first toothed plate drives the central gear to rotate, the second toothed plate will move away from the first placing plate side under the meshing of the central gear. Therefore, the second toothed plate drives the linkage frame and the lowermost spacer plate to move away from the first placing plate side. After that, the lowermost spacer plate separates from the sheet metal part on its surface. So the sheet metal part will fall from the lowermost spacer plate to the side of the feeding plate, and is pushed to the lower part of the three-dimensional five-axis laser cutting seat along with the pushing of the feeding plate, realizing the function of automatic loading and improving the safety of the sheet metal part during processing.

[0011] Preferably, a first arc block is fixedly installed on the upper surface of the second toothed plate; a second arc block is fixedly installed on the bottom surface of the linkage frame close to the second toothed plate; a tension spring is fixedly connected to the side of the linkage frame close to the first placing plate; the side of the tension spring away from the linkage frame is fixedly connected to the surface of the first placing plate. When the second toothed plate moves, the first arc block on its surface will contact the second arc block.

[0012] During operation, when the second toothed plate moves, the second toothed plate will drive the first arc block on its surface to move at the same time. The first arc block will contact the second arc block and pull the second arc block and the linkage frame, so that the second arc block drives the linkage frame and the lowermost spacer plate to move away from the first placing plate side and pull the tension spring. When the lowermost spacer plate separates from the sheet metal part, at this time the first arc block and the second arc block will also separate from each other. When the tension spring returns from the telescopic state, it will drive the spacer plate to recover, facilitating the lowermost spacer plate to support and place the upper sheet metal part, which is beneficial to ejecting the sheet metal part individually and realizing the function of automatic feeding, making it safer and more convenient to use.

[0013] Preferably, the diameter of the first arc block is larger than that of the second arc block; a limiting frame adapted to the second toothed plate is arranged on the upper surface of the support plate. During operation, since the diameter of the first arc block is larger than that of the second arc block, it is convenient for the first arc block to drive the second arc block and the linkage frame to move, which is beneficial to the separation and placement of the spacer plate and the sheet metal part.

[0014] Preferably, a rotating disc is rotatably connected to the upper surface of the support plate through a vertical frame; the rotating disc is arranged close to one side of the linkage frame; the rotating disc and the central gear are connected by a belt; a plurality of arc-shaped columns are fixedly installed on the surface of the rotating disc; a rectangular frame is fixedly installed on the surface of the spacer plate, and the rectangular frame is arranged on the surface of the penultimate spacer plate; an arc-shaped groove is formed on the lower surface of the rectangular frame; when the rotating disc rotates, the arc-shaped columns on its surface will contact the arc-shaped groove; during operation, when the central gear rotates, the central gear will drive the rotating disc to rotate through the belt, the rotating disc drives the arc-shaped columns to rotate, and the arc-shaped columns will contact the arc-shaped groove on the bottom surface of the rectangular frame during rotation, so that the arc-shaped columns drive the rectangular frame to move during rotation, and the rectangular frame drives the penultimate spacer plate away from the first placement plate. At this time, when the lowermost spacer plate returns to its initial state under the action of the tension spring, the sheet metal part on the surface of the penultimate spacer plate will fall onto the surface of the lowermost spacer plate, realizing the function of pushing the sheet metal part while also serving as a feeding function, not only achieving an intermittent feeding effect, but also improving the safety during feeding.

[0015] Preferably, a telescopic column is fixedly installed on the surface of the rectangular frame close to one side of the first placement plate; a limiting spring is sleeved on the outer surface of the telescopic column; the side of the limiting spring away from the rectangular frame is fixedly connected to the surface of the first placement plate; during operation, when the arc-shaped column drives the rectangular frame to move, it will simultaneously pull the limiting spring on its side surface. Then, when the arc-shaped column disengages from the arc-shaped groove on the bottom surface of the rectangular frame, the limiting spring will return from the stretched state, so that the penultimate spacer plate can be restored, facilitating the re-placement of the sheet metal part.

[0016] Preferably, the inner wall of the arc-shaped groove is chamfered; the arc-shaped column and the arc-shaped groove are adapted in shape; the top of the arc-shaped column is arc-shaped; during operation, the inner wall of the arc-shaped groove is chamfered and the top of the arc-shaped column is arc-shaped, which is beneficial for the arc-shaped column to be stuck into and gradually disengage from the arc-shaped groove, facilitating the movement of the rectangular frame.

[0017] Preferably, a plurality of grooves are fixedly installed on the inner wall of the second placement plate, and rollers are rotatably connected in the grooves on the inner wall of the second placement plate; the plurality of rollers and the plurality of spacer plates are arranged in one-to-one correspondence; during operation, when one side of the spacer plate withdraws the sheet metal part, since the other side of the sheet metal part is supported by the roller, when the spacer plate tilts, under the action of the roller, it will slowly fall to one side of the feeding plate, and then the sheet metal part can be pushed out through the feeding plate, making the use safer.

[0018] Preferably, the shape of the support plate on the side close to the three-dimensional five-axis laser cutting seat is inclined; a rotating rod adapted to the roller is arranged on the inner wall of the second placement plate; since the shape of one side of the support plate is inclined, it is beneficial for the sheet metal part to fall onto the workbench surface as soon as possible.

[0019] Preferably, a plurality of transmission wheels are rotatably connected above the inclined surface of the support plate; the plurality of transmission wheels are connected by an external driving motor; during operation, the transmission wheels are provided, and through the transmission of the transmission wheels, the conveying of the sheet metal parts can be accelerated.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. For the three-dimensional five-axis laser cutting device for sheet metal processing of the present invention, by arranging the sheet metal parts at intervals from top to bottom in sequence, it is relatively convenient to push out the lowermost sheet metal part. This not only avoids the problem that when the sheet metal parts are stacked together, the bottom of them bears a large gravity during pushing, making it inconvenient to push out the sheet metal parts; but also solves the problem that when the sheet metal parts are stacked together and pushed out, they rub against each other, easily causing scratches on the surface of the sheet metal parts; at the same time, since a small amount of dust is generated during laser cutting, the embodiment of the present invention also avoids the problem that manual feeding causes the staff to inhale some dust and affects their health.

[0022] 2. For the three-dimensional five-axis laser cutting device for sheet metal processing of the present invention, the second toothed plate drives the linkage frame and the lowermost spacer plate to move away from the first placement plate. After that, the lowermost spacer plate disengages from the sheet metal part on its surface. Therefore, the sheet metal part will fall to one side of the feeding plate from the lowermost spacer plate, and is pushed to below the three-dimensional five-axis laser cutting seat along with the pushing of the feeding plate, realizing the function of automatic feeding and improving the safety of the sheet metal part during processing.

[0023] 3. For the three-dimensional five-axis laser cutting device for sheet metal processing of the present invention, the rectangular frame drives the penultimate spacer plate to move away from the first placement plate. At this time, when the lowermost spacer plate returns to its initial state under the action of the tension spring, the sheet metal part on the surface of the penultimate spacer plate will fall to the surface of the lowermost spacer plate, realizing the function of pushing the sheet metal part while also playing a feeding role. It not only achieves an intermittent feeding effect, but also improves the safety during feeding. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0035] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0036] Embodiment 1

[0037] As Figures 1 to 3 shown, a three-dimensional five-axis laser cutting device for sheet metal processing according to an embodiment of the present invention includes a workbench 1; a three-dimensional five-axis laser cutting seat 2 is fixedly installed on the upper surface of the workbench 1, and the three-dimensional five-axis laser cutting seat 2 is used for cutting sheet metal parts, and it can rotate arbitrarily on the X, Y, and Z axes. This is prior art and will not be elaborated further; a support plate 3 is fixedly installed on the upper surface of the workbench 1 on the side away from the three-dimensional five-axis laser cutting seat 2; a first placement plate 301 and a second placement plate 302 are fixedly installed on the upper surface of the support plate 3; the first placement plate 301 and the second placement plate 302 are arranged at intervals; a plurality of spacer plates 303 for placing sheet metal parts are arranged on the surface of the first placement plate 301, and the plurality of spacer plates 303 are arranged at equal distances; a pushing mechanism is arranged on the upper surface of the support plate 3 near the first placement plate 301, and the pushing mechanism is used for intermittently pushing different sheet metal parts;

[0038] In the prior art, sheet metal parts are stacked together, resulting in a relatively large gravity on the bottom when pushed, which is not convenient for pushing out the sheet metal parts. Moreover, when the sheet metal parts are stacked together and pushed out, the friction between the sheet metal parts is relatively large, and the problem of scratching on the surface of adjacent sheet metal parts is likely to occur.

[0039] During normal use, the sheet metal parts are placed on the surfaces of the spacer plates 303 at different positions, so that the sheet metal parts are arranged at intervals from top to bottom. By operating the three-dimensional five-axis laser cutting seat 2, the sheet metal parts on the surface of the workbench 1 are cut in any direction on the X, Y, and Z axes until the shape of the required sheet metal parts is achieved. When a sheet metal part is processed and needs to be loaded with a new sheet metal part, the external controller drives the pushing mechanism to move. The pushing mechanism pushes the bottommost sheet metal part towards the surface of the workbench 1 until it moves above the workbench 1. At this time, the three-dimensional five-axis laser cutting seat 2 performs laser cutting on the new sheet metal part. In the embodiment of the present invention, the sheet metal parts are arranged at intervals from top to bottom in sequence, which can more conveniently push out the bottommost sheet metal part. This not only avoids the problem that when the sheet metal parts are stacked together, the gravity on the bottom is relatively large when pushed, making it inconvenient to push out the sheet metal parts, but also solves the problem that when the sheet metal parts are stacked together and pushed out, the mutual friction between the sheet metal parts is likely to cause scratching on the surface of the sheet metal parts. At the same time, since a small amount of dust is generated during laser cutting, the embodiment of the present invention also avoids the problem that manual loading may cause some dust to be inhaled by the staff, affecting their health.

[0040] As Figures 2 to 6 shown, the pushing mechanism includes a telescopic cylinder 4 fixedly connected to the upper surface of the support plate 3; the telescopic end of the telescopic cylinder 4 is fixedly connected to a first toothed plate 5; a feeding plate 6 is fixedly installed on the side of the first toothed plate 5 away from the telescopic cylinder 4; two connecting frames 7 are fixedly installed on the upper surface of the support plate 3 near the first toothed plate 5; a central gear 8 is rotatably connected between the two connecting frames 7; a linkage frame 9 is fixedly installed on the surface of the lowermost spacer plate 303; a second toothed plate 10 is arranged on the side of the linkage frame 9 close to the central gear 8; the central gear 8 is respectively meshed with the second toothed plate 10 and the first toothed plate 5;

[0041] During operation, when it is necessary to push out a new sheet metal part, the telescopic end of the telescopic cylinder 4 is controlled to move. Its telescopic end drives the first toothed plate 5 and the feeding plate 6 to move towards the side close to the first placing plate 301. Since the first toothed plate 5 meshes with the central gear 8, and the central gear 8 meshes with the second toothed plate 10, when the first toothed plate 5 drives the central gear 8 to rotate, the second toothed plate 10 will move away from the first placing plate 301 under the meshing of the central gear 8. Therefore, the second toothed plate 10 drives the linkage frame 9 and the lowermost spacer plate 303 to move away from the first placing plate 301. After that, the lowermost spacer plate 303 separates from the sheet metal part on its surface. So the sheet metal part will fall to the side of the feeding plate 6 from the lowermost spacer plate 303, and the sheet metal part will be pushed under the three-dimensional five-axis laser cutting seat 2 along with the push of the feeding plate 6, realizing the function of automatic feeding and improving the safety of the sheet metal part during processing;

[0042] It should be noted that rubber pads are provided on the surfaces of the intermediate partition plate 303 and the support plate 3 in the embodiments of the present invention. The rubber pads have a protective effect to avoid the problem of scratching of the sheet metal part during pushing and falling.

[0043] As Figure 5 shown, a first arc block 11 is fixedly installed on the upper surface of the second toothed plate 10; a second arc block 12 is fixedly installed on the bottom surface of the linkage frame 9 close to the second toothed plate 10; a tension spring 13 is fixedly connected to the side of the linkage frame 9 close to the first placing plate 301; the side of the tension spring 13 away from the linkage frame 9 is fixedly connected to the surface of the first placing plate 301. When the second toothed plate 10 moves, the first arc block 11 on its surface will contact the second arc block 12;

[0044] During operation, when the second toothed plate 10 moves, the second toothed plate 10 will drive the first arc block 11 on its surface to move at the same time. The first arc block 11 will contact the second arc block 12 and pull the second arc block 12 and the linkage frame 9, so that the second arc block 12 drives the linkage frame 9 and the lowermost spacer plate 303 to move away from the first placing plate 301 and pull the tension spring 13. When the lowermost spacer plate 303 separates from the sheet metal part, at this time, the first arc block 11 and the second arc block 12 will also separate from each other. When the tension spring 13 returns from the telescopic state, it will drive the spacer plate 303 to recover, which is convenient for the lowermost spacer plate 303 to support and place the sheet metal part above, facilitating the single pushing out of the sheet metal part and realizing the function of automatic feeding, making it safer and more convenient to use.

[0045] The diameter of the first arc block 11 is greater than that of the second arc block 12; a limiting frame adapted to the second toothed plate 10 is provided on the upper surface of the support plate 3; during operation, since the diameter of the first arc block 11 is greater than that of the second arc block 12, it is convenient for the first arc block 11 to drive the second arc block 12 and the linkage frame 9 to move, which is beneficial to the separation and placement of the spacer plate 303 and the sheet metal part.

[0046] As Figures 4 to 7 shown, a rotating disc 14 is rotatably connected to the upper surface of the support plate 3 through a vertical frame; the rotating disc 14 is arranged close to one side of the linkage frame 9; the rotating disc 14 and the central gear 8 are connected by a belt; a plurality of arc-shaped columns 15 are fixedly installed on the surface of the rotating disc 14; a rectangular frame 16 is fixedly installed on the surface of the spacer plate 303, and the rectangular frame 16 is arranged on the surface of the penultimate layer spacer plate 303; an arc-shaped groove 17 is formed on the lower surface of the rectangular frame 16; when the rotating disc 14 rotates, the arc-shaped columns 15 on its surface will contact the arc-shaped groove 17.

[0047] During operation, when the central gear 8 rotates, the central gear 8 will drive the rotating disc 14 to rotate through the belt, the rotating disc 14 drives the arc-shaped columns 15 to rotate, and the arc-shaped columns 15 will contact the arc-shaped groove 17 on the bottom surface of the rectangular frame 16 during the rotation process, so that the arc-shaped columns 15 drive the rectangular frame 16 to move during the rotation process, and the rectangular frame 16 drives the penultimate layer spacer plate 303 to move away from the first placement plate 301. At this time, when the lowermost spacer plate 303 returns to its initial state under the action of the tension spring 13, the sheet metal part on the surface of the penultimate layer spacer plate 303 will fall onto the surface of the lowermost spacer plate 303, realizing the function of pushing the sheet metal part while also serving as a feeding function, not only achieving an intermittent feeding effect, but also improving the safety during feeding.

[0048] As Figure 7 shown, a telescopic column 18 is fixedly installed on the surface of the rectangular frame 16 close to one side of the first placement plate 301; a limiting spring 19 is sleeved on the outer surface of the telescopic column 18; the side of the limiting spring 19 away from the rectangular frame 16 is fixedly connected to the surface of the first placement plate 301; during operation, when the arc-shaped column 15 drives the rectangular frame 16 to move, it will simultaneously pull the limiting spring 19 on its side surface, and then when the arc-shaped column 15 disengages from the arc-shaped groove 17 on the bottom surface of the rectangular frame 16, the limiting spring 19 will return from the stretched state, so that the penultimate layer spacer plate 303 is restored, facilitating the re-placement of the sheet metal part.

[0049] The inner wall of the arc-shaped groove 17 is chamfered; the shape of the arc-shaped column 15 is adapted to that of the arc-shaped groove 17; the top of the arc-shaped column 15 is arc-shaped; during operation, the inner wall of the arc-shaped groove 17 is chamfered, and the top of the arc-shaped column 15 is arc-shaped, which is beneficial for the arc-shaped column 15 to be inserted into the arc-shaped groove 17 and gradually separated from the arc-shaped groove 17, facilitating the movement of the rectangular frame 16.

[0050] As Figure 8 As shown, a plurality of grooves are fixedly installed on the inner wall of the second placement plate 302, and rollers 20 are rotatably connected in the grooves on the inner wall of the second placement plate 302; the plurality of rollers 20 and the plurality of spacer plates 303 are arranged in one-to-one correspondence; during operation, when one side of the spacer plate 303 is withdrawn from the sheet metal part, since the other side of the sheet metal part is supported by the rollers 20, when the spacer plate 303 is tilted, under the action of the rollers 20, it will slowly fall to one side of the feeding plate 6, and then the sheet metal part can be pushed out through the feeding plate 6, making the use safer.

[0051] The shape of one side of the support plate 3 close to the three-dimensional five-axis laser cutting seat 2 is inclined; a rotating rod adapted to the roller 20 is arranged on the inner wall of the second placement plate 302; since the shape of one side of the support plate 3 is inclined, it is beneficial for the sheet metal part to fall onto the surface of the workbench 1 as soon as possible.

[0052] Embodiment 2

[0053] As Figure 9 As shown, compared with Embodiment 1, another implementation manner of the present invention is: a plurality of transmission wheels 21 are rotatably connected above the inclined surface of the support plate 3; the plurality of transmission wheels 21 are connected by an external driving motor; during operation, the transmission wheels 21 are provided, and through the transmission of the transmission wheels 21, the conveying of the sheet metal part can be accelerated.

[0054] During operation, the sheet metal parts are placed on the surfaces of the spacer plates 303 at different positions, so that the sheet metal parts are arranged at intervals from top to bottom. By operating the three-dimensional five-axis laser cutting seat 2, the sheet metal parts on the surface of the workbench 1 are cut in any direction on the X, Y, and Z axes until the required shape of the sheet metal parts is achieved. When a sheet metal part is processed and needs to be loaded, by controlling the movement of the telescopic end of the telescopic cylinder 4, the telescopic end drives the first toothed plate 5 and the feeding plate 6 to move towards the side close to the first placing plate 301. Since the first toothed plate 5 meshes with the central gear 8, and the central gear 8 meshes with the second toothed plate 10, when the first toothed plate 5 drives the central gear 8 to rotate, the second toothed plate 10 will move away from the first placing plate 301 under the meshing of the central gear 8. Therefore, the second toothed plate 10 drives the linkage frame 9 and the lowermost spacer plate 303 to move away from the first placing plate 301. After that, the lowermost spacer plate 303 separates from the sheet metal part on its surface, so the sheet metal part will fall to the side of the feeding plate 6 and is pushed to the lower part of the three-dimensional five-axis laser cutting seat 2 along with the push of the feeding plate 6, realizing the function of automatic feeding and improving the safety of the sheet metal parts during processing;

[0055] When the second toothed plate 10 moves, the second toothed plate 10 will simultaneously drive the first arc block 11 on its surface to move. The first arc block 11 will contact the second arc block 12 and pull the second arc block 12 and the linkage frame 9, so that the second arc block 12 drives the linkage frame 9 and the lowermost spacer plate 303 to move away from the first placing plate 301 and pull the tension spring 13. When the lowermost spacer plate 303 separates from the sheet metal part, at this time, the first arc block 11 and the second arc block 12 will also separate from each other. When the tension spring 13 returns from the telescopic state, it will drive the spacer plate 303 to recover, facilitating the lowermost spacer plate 303 to support and place the upper sheet metal part, which is conducive to pushing out the sheet metal parts individually and realizing the function of automatic feeding, making it safer and more convenient to use;

[0056] When the central gear 8 rotates, the central gear 8 drives the rotating disk 14 to rotate through a belt. The rotating disk 14 drives the arc-shaped column 15 to rotate. During the rotation of the arc-shaped column 15, it will contact the arc-shaped groove 17 on the bottom surface of the rectangular frame 16, causing the arc-shaped column 15 to drive the rectangular frame 16 to move during rotation. The rectangular frame 16 drives the spacer 303 on the penultimate layer away from the first placement plate 301. At this time, when the lowermost spacer 303 returns to its initial state under the action of the tension spring 13, the sheet metal parts on the surface of the spacer 303 on the penultimate layer will fall onto the surface of the lowermost spacer 303, realizing the function of pushing the sheet metal parts while also serving as a feeding function. It not only achieves an intermittent feeding effect but also improves the safety during feeding. When the arc-shaped column 15 drives the rectangular frame 16 to move, it will simultaneously pull the limiting spring 19 on its side surface. Then, when the arc-shaped column 15 disengages from the arc-shaped groove 17 on the bottom surface of the rectangular frame 16, the limiting spring 19 will return from the stretched state, so that the spacer 303 on the penultimate layer is restored, facilitating the re-placement of the sheet metal parts. When the spacer 303 on one side withdraws from the sheet metal part, since the other side of the sheet metal part is supported by the roller 20, when the spacer 303 tilts, under the action of the roller 20, it will slowly fall to one side of the feeding plate 6, and then the sheet metal part can be pushed out through the feeding plate 6, making it safer to use.

[0057] In the embodiment of the present invention, the sheet metal parts are arranged at intervals from top to bottom, which can more conveniently push out the sheet metal part at the bottom. It not only avoids the problem that when the sheet metal parts are stacked together, the gravity on the bottom is too large when being pushed, making it inconvenient to push out the sheet metal parts; but also solves the problem that when the sheet metal parts are stacked together and pushed out, they will rub against each other, easily causing scratches on the surface of the sheet metal parts. At the same time, since a small amount of dust is generated during laser cutting, the embodiment of the present invention also avoids the problem that manual feeding may cause staff to inhale some dust and affect their health.

[0058] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
