Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, in particular to a galvanized plate laser cutting device. Background Art

[0002] Galvanized sheet is a metal material with a layer of zinc coated on the surface of the steel sheet. This treatment not only enhances the corrosion resistance of the steel, but also extends its service life. Its main functions include preventing the steel from rusting and improving its durability in outdoor environments while maintaining good mechanical properties and processability. It is widely used in construction, transportation, home appliances and other industries, which is both economical and safe.

[0003] In the process of cutting galvanized sheet by laser cutting device, the galvanized sheet is prepared by cutting it according to the required size and shape, and the galvanized sheet is placed on the cutting platform. After the laser is started, the laser beam will be focused to a very small point through the optical system. The high energy of this point causes the zinc layer on the surface of the galvanized sheet and the steel sheet itself to melt and evaporate rapidly, and then break, thereby achieving the purpose of cutting the galvanized sheet.

[0004] There are still many inconveniences in the use of current equipment: when the laser cutting device cuts the galvanized sheet at a certain position, the zinc layer or protective film on the surface of the galvanized sheet melts under the action of high temperature, and splashing is prone to occur. The splashed material will fall on the unprocessed surface of the galvanized sheet and adhere to it. After the splashed zinc layer or protective film adheres to the unprocessed surface, an irregular or raised surface will be formed, which will cause the laser beam to be unable to penetrate the material evenly during cutting, thereby affecting the cutting accuracy and the flatness of the cutting edge.

[0021] refer to Figures 1 to 8 A galvanized sheet laser cutting device according to a preferred embodiment of the present invention will be described in detail below. A galvanized sheet laser cutting device includes a box body 1, a tooth plate is fixedly connected to the inside of the box body 1, a cutting mechanism 2 for cutting the galvanized sheet is arranged on the surface of the box body 1, a pushing mechanism 3 for pushing the galvanized sheet to automatically feed is arranged on the surface of the box body 1, a collecting mechanism 4 for automatically collecting the cut pieces is arranged inside the box body 1, and a protection mechanism 5 for protecting the collected cut pieces is arranged inside the box body 1; The cutting mechanism 2 includes a side slide rail 211, which is fixedly connected to the upper surface of the box body 1, a driving block 212 is slidably connected to the surface of the side slide rail 211, a transverse slide rail 213 is fixedly connected to the surface of the driving block 212, a laser assembly 214 is slidably connected to the surface of the transverse slide rail 213, and a galvanized steel plate 215 is slidably connected to the surface of the toothed plate inside the box body 1; like Figure 1 In the embodiment, the propulsion mechanism 3 includes a power gear 311, which is rotatably connected to the surface of the box body 1, and a push rod 312 is fixedly connected to the surface of the power gear 311. A power slider 314 is slidably connected to the inside of the box body 1, and a push rod 313 is rotatably connected to the surface of the power slider 314. One end of the push rod 313 is rotatably connected to the surface of one end of the push rod 312. When a position of the galvanized steel plate 215 is cut through the cutting mechanism 2 to complete the cutting task, the motor drives the power gear 311 to rotate, and a pulling force is given to the push rod 313 through the push rod 312 on the surface of the power gear 311, thereby pulling the power slider 314 to slide. Figure 1 and Figure 2The surface of the power slider 314 is rotatably connected with a push block 315, and the surface of the power slider 314 is fixedly connected with a rebound pick 317 and a limit shaft 316. A push slot 318 is provided on the surface of the galvanized steel plate 215, and the push block 315 extends to the inside of the push slot 318. The rebound pick 317 and the limit shaft 316 are both located inside the sliding path of the push block 315. The rebound pick 317 and the limit shaft 316 are respectively located on both sides of the push block 315. The surface of the power gear 311 is provided with a tooth block that surrounds half a circle. At this time, the push block 315 on the surface of the power slider 314 is located inside the push slot 318 on the surface of the galvanized steel plate 215. The power slider 314 slides in the direction of the horizontal slide rail. Since the limit shaft 316 gives a restriction to the push block 315, The push block 315 cannot rotate counterclockwise, the power slider 314 slides in the direction of the horizontal slide rail, and then gives the inner wall of the pushing slot 318 a thrust in the direction of the horizontal slide rail through the push block 315, thereby pushing the galvanized steel plate 215 to slide in the direction of the horizontal slide rail, thereby advancing the galvanized steel plate 215 on the surface of the toothed plate. As the power gear 311 continues to rotate, the power gear 311 pulls the power slider 314 to slide in the opposite direction through the power gear 311 and the No. 1 push rod 312, and the push block 315 contacts the inclined surface of the pushing slot 318, and the push block 315 rotates clockwise. At this time, the rebound paddle 317 is compressed and retracted under the push of the push block 315 until the power slider 314 slides to the initial position, and the push block 315 re-extends to the inside of the pushing slot 318, as shown in FIG. Figure 3The cam 3142 is a substantially parallel plate 3160 which is provided on the upper and lower surfaces of the lifter 3100. The cam 3142 is a substantially parallel plate 3160 which is provided on the upper and lower surfaces of the lifter 3100. The cam 3142 is a substantially parallel plate 3160 which is provided on the lower and upper surfaces of the lifter 3100. The movable adjustment slide 3111 slides, and a downward thrust is given to the rotating sliding shaft 3114 through the descending groove on the surface of the adjustment slide 3111, thereby driving the surface shovel 319 to slide downward. As the surface shovel 319 continues to slide down, the swing gear 3115 contacts the tooth block on the surface of the fixed top frame 3113, and the surface shovel 319 rotates clockwise under the drive of the swing gear 3115 to become an inclined state. When the power slider 314 slides to the bottom of the descending groove on the surface of the adjustment slide 3111, the surface shovel 319 contacts the surface of the galvanized steel plate 215. As the galvanized steel plate 215 slides toward the horizontal slide rail 213 under the push of the pushing block 315, the impurities on the surface of the galvanized steel plate 215 are cleaned, and the impurities are collected by the surface shovel 319 through the dust suction pipe 3116 to the inside of the material receiving box 3112, thereby ensuring the flatness of the cutting range of the galvanized steel plate 215 and improving the cutting accuracy of the galvanized steel plate 215.

[0022] like Figure 4 In the embodiment, the collecting mechanism 4 includes a sliding outer frame 411, which is slidably connected to the inside of the box body 1, and a tooth block is arranged on the surface of the sliding outer frame 411, and the tooth block on the surface of the sliding outer frame 411 meshes with the sliding outer frame 411. A spring 414 is fixedly connected to the inside of the box body 1, and the spring 414 is fixedly connected to the sliding outer frame 411. A center plate 412 is fixedly connected to the surface of the sliding outer frame 411, and a plurality of fixed circular frames 413 are fixedly connected to the lower surface of the center plate 412. When the galvanized During the process of the steel plate 215 being automatically advanced under the action of the advancement mechanism 3, the cut pieces of the galvanized steel plate 215 that have been cut are still attached to the surface of the galvanized steel plate 215 until the cut pieces are pushed to the bottom of the center stop plate 412 by the advancement mechanism 3. When the power slider 314 slides away from the horizontal slide rail to restore, the gear block of the power gear 311 rotates to the other side, and the power gear 311 pushes the sliding outer frame 411 to slide down, thereby driving the fixed circular frame 413 on the lower surface of the center stop plate 412 to slide down. Figure 6 In the embodiment, the interior of the fixed circular frame 413 is slidably connected with a demoulding shaft 415, and the interior of the fixed circular frame 413 is fixedly connected with a No. 2 spring 416, and the No. 2 spring 416 is fixedly connected to the demoulding shaft 415. At this time, the demoulding shaft 415 inside the fixed circular frame 413 contacts the surface of the galvanized steel plate 215. When the demoulding shaft 415 contacts the uncut part of the galvanized steel plate 215, the demoulding shaft 415 will shrink to the inside of the fixed circular frame 413 under the restriction of the galvanized steel plate 215. When the demoulding shaft 415 contacts the cutting piece on the surface of the galvanized steel plate 215, the demoulding shaft 415 will give the cutting piece a downward thrust, and push the cutting piece to fall into the interior of the protective mechanism 5 for centralized collection. The cutting piece is collected by the collecting mechanism 4 without waiting for manual intervention, thereby reducing the pause time in the production process, improving the overall production efficiency, and avoiding the problem of the cutting piece staying on the surface of the box body 1, thereby blocking the subsequent advancement and cutting of the galvanized steel plate 215.

[0023] like Figure 7 In the embodiment, the protection mechanism 5 includes a protection plate 511, a collecting groove 513 is provided inside the box body 1, the protection plate 511 is slidably connected to the inside of the collecting groove 513, and a fixed side plate 512 is fixedly connected to the inner wall of the collecting groove 513. Figure 7 and Figure 8In the embodiment, the surface of the fixed side plate 512 is rotatably connected to the first support rod 517, the surface of the second sliding shaft 516 is sleeved with the second support rod 518, one end of the second support rod 518 is rotatably connected to one end surface of the first support rod 517, the interior of the box body 1 is rotatably connected to the connecting shaft 5110, the first support rod 517 is rotatably connected to one end surface of the connecting shaft 5110, the interior of the box body 1 is rotatably connected to the adjusting gear 5111, the adjusting gear 5111 is fixedly connected to one end surface of the connecting shaft 5110, the lower surface of the sliding outer frame 411 is fixedly connected to the adjusting gear rod 5112, the adjusting gear rod 5112 is fixedly connected to the lower surface of the sliding outer frame 411, and the adjusting gear rod 5112 is fixedly connected to the lower surface of the sliding outer frame 411. 12 is meshed with the adjusting gear 5111. When the sliding outer frame 411 descends under the push of the power gear 311, the sliding outer frame 411 drives the adjusting gear rod 5112 to slide downward, thereby driving the adjusting gear 5111 to rotate, and driving the No. 1 support rod 517 to rotate on the surface of the fixed side plate 512 through the connecting shaft 5110, thereby giving the No. 1 support rod 517 an upward thrust, and then giving the protective block 514 an upward thrust through the No. 2 sliding shaft 516. The surface of the fixed side plate 512 is provided with an adjusting groove 519, and the adjusting groove 519 is composed of a straight sliding groove and a curved groove. The length of the straight slide groove of the adjustment groove 519 is twice the length of the radius of the arc groove of the adjustment groove 519. The interior of the adjustment groove 519 is slidably connected with the first slide shaft 515 and the second slide shaft 516. The lower surface of the protection plate 511 is fixedly connected with a protection block 514. The protection block 514 is Z-shaped and sleeved on the surfaces of the first slide shaft 515 and the second slide shaft 516. The first slide shaft 515 slides to the top of the straight slide groove of the adjustment groove 519. At this time, the protection plate 511 is separated from the interior of the collection groove 513. As the second support rod 518 continues to slide upward, the second slide shaft 516 extends to the adjustment groove 519. The arc groove part realizes the folding of the protection plate 511 through the protection stop block 514. At this time, the protection plate 511 fits with the toothed plate part on the surface of the box body 1, thereby providing a stable space for collecting the cut pieces on the surface of the galvanized steel plate 215, and when the sliding outer frame 411 rises, the protection plate 511 will re-extend to the interior of the collecting groove 513 and then seal the collecting groove 513, avoiding the welding slag and other impurities generated during the cutting process of the galvanized steel plate 215 on the toothed plate surface of the box body 1 from splashing into the interior of the collecting groove 513 and then damaging the cut pieces inside the collecting groove 513, thereby improving the reliability of the product.

[0024] The following is the entire working process and working principle of the above-mentioned embodiment: when the galvanized steel plate 215 has completed the cutting task at one position through the cutting mechanism 2, the motor drives the power gear 311 to rotate, and the No. 1 push rod 312 on the surface of the power gear 311 gives a pulling force to the No. 2 push rod 313, thereby pulling the power slider 314 to slide. Since the pushing block 315 on the surface of the power slider 314 is located inside the pushing slot 318 on the surface of the galvanized steel plate 215 at this time, the power slider 314 slides in the direction of the horizontal slide rail. Since the limit shaft 316 gives a restriction to the pushing block 315, the pushing block 315 cannot rotate counterclockwise, and the power slider 314 slides in the direction of the horizontal slide rail and then gives the inner wall of the pushing slot 318 a horizontal force through the pushing block 315. The thrust in the direction of the slide rail pushes the galvanized steel plate 215 to slide in the direction of the horizontal slide rail, thereby pushing the galvanized steel plate 215 on the surface of the toothed plate. As the power gear 311 continues to rotate, the power gear 311 pulls the power slider 314 to slide in the opposite direction through the power gear 311 and the No. 1 push rod 312, pushing the stop block 315 to contact the inclined surface of the pushing slot 318, pushing the stop block 315 to rotate clockwise. At this time, the rebound paddle 317 is compressed and retracted under the push of the push stop block 315 until the power slider 314 slides to the initial position, pushing the stop block 315 to re-extend to the inside of the pushing slot 318, and when the adjusting slide plate 3111 slides in the direction of the driving block 212, the power slide block 314 pushes the adjusting slide plate 3111 to slide , by adjusting the descending groove on the surface of the sliding plate 3111, a downward thrust is given to the rotating sliding shaft 3114, thereby driving the surface shovel 319 to slide downward. As the surface shovel 319 continues to slide downward, the swing gear 3115 contacts the tooth block on the surface of the fixed top frame 3113, and the surface shovel 319 rotates clockwise under the drive of the swing gear 3115 to become an inclined state. When the power sliding block 314 slides to the bottom of the descending groove on the surface of the adjusting sliding plate 3111, the surface shovel 319 contacts the surface of the galvanized steel plate 215. As the galvanized steel plate 215 slides toward the horizontal slide rail 213 under the push of the pushing block 315, the impurities on the surface of the galvanized steel plate 215 are cleaned by the surface shovel 319, and the impurities are collected by the surface shovel 319 through the dust suction pipe 3116 to The inside of the material receiving box 3112 ensures the flatness of the cutting range of the galvanized steel plate 215 and improves the cutting accuracy of the galvanized steel plate 215. When the galvanized steel plate 215 is automatically advanced under the action of the advancing mechanism 3, the cut pieces of the galvanized steel plate 215 that have completed cutting are still attached to the surface of the galvanized steel plate 215 until the cut pieces are pushed to the bottom of the center abutment plate 412 by the advancing mechanism 3. When the power slider 314 slides away from the horizontal slide rail for recovery, the power gear 311 tooth block rotates to another time, and the power gear 311 pushes the sliding outer frame 411 to slide down, thereby driving the fixed circular frame 413 on the lower surface of the center abutment plate 412 to slide down. At this time, the demoulding abutment shaft 415 inside the fixed circular frame 413 contacts the surface of the galvanized steel plate 215.When the demoulding shaft 415 contacts the uncut part of the galvanized steel plate 215, the demoulding shaft 415 will shrink to the inside of the fixed circular frame 413 under the restriction of the galvanized steel plate 215. When the demoulding shaft 415 contacts the cutting piece on the surface of the galvanized steel plate 215, the demoulding shaft 415 will give the cutting piece a downward thrust, and push the cutting piece to fall into the inside of the protective mechanism 5 for centralized collection. The cutting pieces are collected by the collecting mechanism 4 without waiting for manual intervention, which reduces the pause time in the production process, improves the overall production efficiency, and avoids the problem of the cutting pieces staying on the surface of the box body 1, thereby blocking the subsequent advancement and cutting of the galvanized steel plate 215. Through the cooperation of the collecting mechanism 4 and the protective mechanism 5, when the sliding outer frame 411 descends under the push of the power gear 311, the sliding outer frame 411 drives the adjusting gear rod 5112 to slide downward, thereby driving the adjusting gear 5111 to rotate, and drives the No. 1 support rod 517 to the fixed side plate 51 through the connecting shaft 5110. 2, thereby giving an upward thrust to the No. 1 support rod 517, and then giving an upward thrust to the protection block 514 through the No. 2 sliding shaft 516, until the No. 1 sliding shaft 515 slides to the top of the straight sliding groove of the adjustment groove 519, at which time the protection plate 511 is separated from the inside of the collection groove 513, and as the No. 2 support rod 518 continues to slide upward, the No. 2 sliding shaft 516 extends to the arc groove part of the adjustment groove 519, and the protection block 514 realizes the folding of the protection plate 511, at which time the protection plate 511 is partially fitted with the toothed plate on the surface of the box body 1, thereby providing a stable space for collecting the cut pieces on the surface of the galvanized steel plate 215, and when the sliding outer frame 411 rises, the protective plate 511 will re-extend to the inside of the collection tank 513 and seal the collection tank 513, avoiding the welding slag and other impurities generated during the cutting process of the galvanized steel plate 215 on the surface of the toothed plate of the box body 1 from splashing into the inside of the collection tank 513 and damaging the cut pieces inside the collection tank 513, thereby improving the reliability of the product.
