Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a laser cutting device for stainless steel nameplates, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A laser cutting device for stainless steel nameplates, comprising a base, a U-shaped beam slidably mounted on the side of the base, a laser cutting head slidably mounted on the top of the U-shaped beam, a support platform fixedly mounted on the inner side of the U-shaped beam, a detection pressure rod slidingly passing through the bottom of the support platform, a hydraulic cylinder fixedly mounted on the top of the support platform, a trapezoidal top block slidably mounted on the top of the U-shaped beam, a hydraulic rod slidably mounted on the inner inner wall of the hydraulic cylinder, the side end face of the hydraulic rod is fixedly connected to the side face of the trapezoidal top block, a lifting plate fixedly connected to the top of the U-shaped beam by a spring, a limit block slidably mounted on the bottom of the lifting plate, a sliding block slidably mounted on the top of the U-shaped beam, a supporting tooth group is provided inside the base, and a collecting groove is provided on the front end surface of the base. The thickness of the stainless steel nameplate to be processed is detected by the detection pressure rod to drive the limit block to limit the falling distance of the laser cutting head, thereby avoiding the laser cutting head contacting with the stainless steel nameplate and causing damage due to failure to adjust the processing program in time after reloading.

[0007] According to the above technical solution, the top circumferential surface of the detection pressure rod contacts the inner wall of the hydraulic cylinder, the bottom of the trapezoidal top block contacts the top of the lifting plate, and the lifting plate is located on the movement trajectory of the trapezoidal top block. A height limit groove is provided at the bottom of the laser cutting head, and the limit block is located on the movement trajectory of the height limit groove. A horizontal limit groove is provided at the rear end of the laser cutting head, and the side of the sliding block contacts the inner wall side of the horizontal limit groove. The limit block is located on the movement trajectory of the laser cutting head. A reciprocating spring is arranged between the limit block and the lifting plate, and the rear part of the limit block is fixedly connected to the bottom of the sliding block. The limitation of the laser cutting head by the sliding block avoids direct processing without confirming the thickness of the stainless steel nameplate before processing, thereby further improving the overall safety of the device.

[0008] According to the above technical solution, a positioning frame is provided inside the base, a pulley group is provided inside the positioning frame, a bevel hook is fixedly connected to the top front of the positioning frame, a sliding top block is slidably installed on the top inside the base, and an extended connecting rod is fixedly connected to the side of the sliding top block. After the processing is completed, the U-shaped crossbeam drives the positioning frame and the pulley group to slide upward during the unloading process, so that the sliding friction between the stainless steel nameplate and the supporting tooth group during the unloading process is converted into rolling friction, making the unloading process smoother.

[0009] According to the above technical solution, a sliding splint is inserted through the side of the base, an arc-convex top block is fixedly connected to the top of the sliding splint, and a small convex top block is fixedly connected to the top of the positioning frame. The sliding of the small convex top block drives the sliding splint to slide by contacting and squeezing the arc-convex top block, thereby avoiding the misalignment of the stainless steel nameplate caused by the positioning frame driving the pulley group to slide downward during the loading process.

[0010] According to the above technical solution, the bottom of the bevel hook contacts the top of the base, the bevel hook is located on the movement trajectory of the support platform, the positioning frame is located on the movement trajectory of the sliding top block, the extended connecting rod is located on the movement trajectory of the U-shaped beam, and the arc convex top block is located on the movement trajectory of the small convex top block. A reciprocating spring 2 is arranged between the extended connecting rod and the base, and a reciprocating spring 3 is arranged between the sliding splint and the base. The convex surface of the small convex top block and the convex surface of the arc convex top block realize that the stainless steel nameplate is only positioned and clamped once during the loading process, thereby avoiding the bending of the thinner stainless steel nameplate caused by long-term clamping.

[0011] According to the above technical solution, a collection box is fixedly installed at the front end of the base, a support bar is fixedly connected to the inside of the positioning frame, and a rotating scraper is rotatably installed at the bottom of the support bar. The rotating scraper realizes periodic scraping of debris on the top of the inside of the base. At the same time, multiple rotating scrapers realize the collection of the scraped debris into the collection box through the collection trough.

[0012] According to the above technical solution, a pressing lever is rotatably installed inside the collection trough, a debris pressure plate is slidably installed on the inner wall of the collection trough, an L-shaped top block is fixedly installed on the rear of the positioning frame, and a dead corner scraper is slidably installed on the bottom of the base. The dead corner scraper can scrape away the debris accumulated at the bottom of the rear end of the base, thereby avoiding the accumulation of debris caused by dead corners inside the device.

[0013] According to the above technical solution, the bottom of the rotating scraper contacts the top inside the base, the pressing lever is located on the movement trajectory of the positioning frame, the debris pressure plate is located on the movement trajectory of the pressing lever, and the dead angle scraper is located on the movement trajectory of the L-shaped top block. A reset spring is arranged between the dead angle scraper and the base. The positioning frame drives the debris pressure plate to extrude and shape the debris through the pressing lever, thereby avoiding dust before the debris enters the collection box.

[0014] The present invention provides a laser cutting device for stainless steel nameplates. It has the following beneficial effects: (1) This invention detects the thickness of the stainless steel nameplate to be processed by a pressure rod to drive the limit block to limit the falling distance of the laser cutting head, thereby avoiding the situation where the thickness of the stainless steel nameplate to be processed is too thick after reloading and the processing program is not adjusted in time, resulting in the laser cutting head contacting the stainless steel nameplate and causing damage. At the same time, the limit of the laser cutting head by the sliding block avoids direct processing without confirming the thickness of the stainless steel nameplate before processing, further improving the overall safety of the device.

[0015] (2) This invention uses a positioning frame to drive the pulley group to slide, converting the sliding friction during the loading and unloading process into rolling friction, thereby avoiding scratches caused by the heavy weight of the stainless steel nameplate to be processed sliding between its bottom and the device, and making the unloading process smoother, thereby improving the continuity of the device during long-term continuous processing. At the same time, the positioning frame and the small convex top block drive the sliding splint to slide, thereby avoiding the misalignment of the stainless steel nameplate when the positioning frame drives the pulley group to slide downward during the loading process, thereby optimizing the processing flow and processing stability.

[0016] (3) This invention scrapes away the debris generated by the bottom processing of the base by the reciprocating sliding of the positioning frame up and down, and at the same time, the positioning frame drives the dead angle scraper to scrape away the debris at the bottom of the rear end of the base through the L-shaped top block, so that the debris at the rear end of the device can be pushed out and scraped out by the rotating scraper, thereby avoiding the accumulation of debris at the rear end of the base. At the same time, the positioning frame drives the debris pressing plate to squeeze the debris tightly by pressing the lever, thereby avoiding the dust phenomenon before the powdery debris enters the collection box.

After the processing is completed, the U-shaped crossbeam 2 drives the positioning frame 501 and the pulley group 502 to slide upward during the blanking process, so that the sliding friction between the stainless steel nameplate and the supporting tooth group 7 during the blanking process is converted into rolling friction, making the blanking process smoother.

A small convex top block is fixedly connected to the top of the positioning frame 501.

[0024] The bottom of the bevel hook 503 contacts the top of the base 1, the bevel hook 503 is located on the movement trajectory of the support platform 401, the positioning frame 501 is located on the movement trajectory of the sliding top block 504, the extended connecting rod 505 is located on the movement trajectory of the U-shaped beam 2, the arc convex top block 506 is located on the movement trajectory of the small convex top block, and a reciprocating spring 2 is arranged between the extended connecting rod 505 and the base 1, and a reciprocating spring 3 is arranged between the sliding splint 507 and the base 1. The convex surface of the small convex top block and the convex surface of the arc convex top block 506 realize that the stainless steel nameplate is only positioned and clamped once during the loading process, thereby avoiding the bending of the thinner stainless steel nameplate caused by long-term clamping.

[0025] A collection box 601 is fixedly installed at the front end of the base 1, a support bar 602 is fixedly connected to the inside of the positioning frame 501, and a rotating scraper 603 is rotatably installed at the bottom of the support bar 602. The rotating scraper 603 realizes the periodic scraping of debris on the top of the inside of the base 1. At the same time, multiple rotating scrapers 603 realize the collection of the scraped debris into the collection box 601 through the collection trough 8.

[0026] A pressing lever 604 is rotatably installed inside the collecting trough 8, a debris pressure plate 605 is slidably installed on the inner wall of the collecting trough 8, an L-shaped top block 606 is fixedly installed on the rear of the positioning frame 501, and a dead corner scraper 607 is slidably installed on the bottom of the base 1. The dead corner scraper 607 can scrape off the debris accumulated at the bottom of the rear end of the base 1, thereby avoiding the accumulation of debris caused by dead corners inside the device.

[0027] The bottom of the rotating scraper 603 contacts the top inside the base 1, the pressing lever 604 is located on the movement trajectory of the positioning frame 501, the debris pressure plate 605 is located on the movement trajectory of the pressing lever 604, and the dead angle scraper 607 is located on the movement trajectory of the L-shaped top block 606. A return spring is arranged between the dead angle scraper 607 and the base 1. The positioning frame 501 drives the debris pressure plate 605 to extrude and shape the debris through the pressing lever 604, thereby avoiding dust before the debris enters the collection box 601.

[0028] During operation: start the device before processing the stainless steel nameplate, so that the device enters the working state, and prevent the stainless steel nameplate to be processed from being above the supporting tooth group 7. If the thickness of the stainless steel nameplate to be processed is too thick, causing the top of the stainless steel nameplate to contact the bottom of the detection pressure rod 402, the detection pressure rod 402 will slide upward under the extrusion force of the stainless steel nameplate. The upward sliding of the detection pressure rod 402 will squeeze the hydraulic oil inside the hydraulic cylinder 403, so that the hydraulic oil is squeezed and pushes the hydraulic rod to slide away from the detection pressure rod 402. The sliding of the hydraulic rod drives the trapezoidal top block 404 to slide. During the sliding process of the trapezoidal top block 404, the inclined surface of the trapezoidal top block 404 contacts the top of the lifting plate 405. Since the lifting plate 405 is fixedly connected to the U-shaped beam 2 through a spring, the lifting The plate 405 slides upward under the contraction force of the spring, and the upward sliding of the lifting plate 405 drives the limit block 406 to move upward together. After the limit block 406 moves upward, the distance between its bottom and the supporting tooth group 7 increases. Since the movement trajectory of the inner wall of the height limit groove at the bottom of the laser cutting head 3 contacts the bottom of the limit block 406, the laser cutting head 3 moves downward before processing to contact with the limit block 406 and since the limit block 406 cannot slide downward, the laser cutting head 3 cannot continue to slide downward after the contact, thereby achieving the goal of reducing the distance the laser cutting head 3 slides downward when the thickness of the stainless steel nameplate to be processed increases, avoiding the contact between the laser cutting head 3 and the top of the stainless steel nameplate to cause damage. Since the motion trajectory of the circumferential surface of the laser cutting head 3 contacts the inclined surface of the front end of the limit block 406, the laser cutting head 3 contacts the limit block 406 during the descent process and drives it to slide backward. The limit block 406 slides backward and drives the sliding block 407 to slide backward together. After the sliding block 407 slides, its side surface is out of contact with the inner wall side surface of the horizontal limit groove, which releases the horizontal limiting effect of the laser cutting head 3, thereby avoiding the direct processing without confirming the thickness of the stainless steel nameplate to be processed, resulting in the laser cutting head removing the stainless steel nameplate and causing damage to the surface.

[0029] When the device has finished processing the stainless steel nameplate, the U-shaped crossbeam 2 slides forward to the frontmost position. When the U-shaped crossbeam 2 slides forward, it drives the support platform 401 to slide together. During the sliding process of the support platform 401, its front end surface contacts the inclined surface of the inclined hook 503, thereby driving the inclined hook 503 to slide upward. The inclined hook 503 slides upward and drives the front part of the positioning frame 501 fixed thereto to slide upward. At the same time, during the sliding process of the U-shaped crossbeam 2 toward the front, its front end contacts the front and rear end surfaces of the extended connecting rod 505, driving the extended connecting rod 505 to slide forward. 5 slides forward, driving the sliding top block 504 to slide forward. Since the motion trajectory of the inclined surface of the sliding top block 504 contacts the rear end surface of the positioning frame 501, the sliding of the sliding top block 504 drives the rear part of the positioning frame 501 to slide upward, thereby realizing the upward sliding of the positioning frame 501 as a whole. The upward sliding of the positioning frame 501 drives the pulley group 502 to slide upward together. After the pulley group 502 slides upward, the circumferential surface of the pulley contacts the bottom of the stainless steel nameplate, thereby realizing the conversion of the sliding friction generated in the blanking process into rolling friction, making the blanking process smoother and After the steel nameplate is removed from the device and reloaded, the U-shaped crossbeam 2 slides backward to return to its initial position. When the U-shaped crossbeam 2 slides backward, it drives the support platform 401 to disengage from the inclined hook 503. At the same time, the front end of the U-shaped crossbeam 2 disengages from the rear end of the extended connecting rod 505. The extended connecting rod 505 slides backward under the rebound force of the reciprocating spring 2, thereby driving the sliding top block 504 to slide backward, so that the rear end surface of the positioning frame 501 is disengaged from the inclined surface of the sliding top block 504, so that the positioning frame 501 slides downward under the action of gravity. When the positioning frame 501 slides downward, it drives the small convex top block to slide downward. When the small convex top block slides downward, its convex surface contacts the convex surface of the arc convex top block 506, thereby driving the arc convex top block 506 to slide in the direction away from the small convex top block. The sliding of the arc convex top block 506 drives the sliding clamping plate 507 to slide together. During the sliding process of the sliding clamping plate 507, its side contacts the side of the stainless steel nameplate, thereby avoiding the misalignment of the stainless steel nameplate when the positioning frame 501 drives the pulley group 502 to slide downward during the loading process. When the small convex top block continues to slide downward, its convex surface disengages from the convex surface of the arc convex top block 506, and the arc convex top block 506 returns to its initial position under the rebound force of the reciprocating spring three.

[0030] During the laser cutting process, debris will accumulate on the top of the base 1. When the positioning frame 501 slides upward, it drives the support bar 602 to slide upward together. After the support bar 602 slides upward, the bottom of the rotating scraper 603 is out of contact with the top of the base 1, so that the rotating scraper 603 rotates backward under the action of gravity. When the positioning frame 501 rotates downward, the support bar 602 drives the bottom of the rotating scraper 603 to slide forward along the top of the base 1. The sliding of the bottom of the rotating scraper 603 drives the debris to slide together, thereby scraping off the debris accumulated on the top of the base 1 and collecting it into the collection box 601 through the collection groove 8. At the same time, when the positioning frame 501 slides downward, the bottom of the L-shaped top block 606 contacts the inclined surface of the dead corner scraper 607, thereby driving the dead corner scraper The corner scraper 607 slides forward, and the sliding of the dead angle scraper 607 realizes the scraping of debris accumulated at the bottom rear end of the base 1. When the positioning frame 501 slides upward, it drives the bottom of the L-shaped top block 606 to disengage from the inclined surface of the dead angle scraper 607, so that the dead angle scraper 607 slides backward to return to its initial position under the rebound force of the return spring. At the same time, the upward sliding of the positioning frame 501 drives the pressing lever 604 to rotate clockwise by contacting the rear end bottom of the pressing lever 604, so that the front end bottom of the pressing lever 604 contacts the top of the debris pressing plate 605 to drive the debris pressing plate 605 to slide downward. When the debris pressing plate 605 slides downward, it contacts the debris and squeezes and shapes the debris, thereby avoiding dust from occurring before the debris enters the collection box 601.
