Description

Technical Field

[0001] The invention relates to the field of punching machines, and more particularly to a punching machine for automobile decorative panels. Background Art

[0002] Automobile decorative panels refer to a kind of support carrier used to decorate and beautify the electrical components of automobile internal facilities, thereby helping technicians to design a more beautified interior environment according to the structure of automobile decorative panels. In the prior art, the processing methods of automobile decorative panels can be divided into: injection molding, stamping, hot pressing and special processing, etc. The stamping processing method is to place the pre-selected automobile decorative raw material panels on the stamping bed, and then press the panels down with a clamp to bend them into shape, so that the pre-selected automobile decorative raw material panels are pressed into decorative panels that need to be installed in different interiors of the car.

[0003] The same is true for the existing processing methods of automobile decorative raw material panels. For example, a Chinese patent with authorization announcement number CN219703126U discloses an automobile decorative panel punching machine. The clamping rod and clamping groove provided in the device can adjust the die-casting shape and die-casting distance of the first lower template and the second upper template, thereby ensuring that the punching machine can safely punch panels, and can also maintain the stability of the punching machine for long-term use, thereby improving the service life of the punching machine.

[0004] It can be seen that most of the existing processing methods for automobile decorative panels are to first place the raw materials of automobile decorative panels on the die-casting machine, and then perform stamping and forming of the corresponding decorative panels. In the actual stamping process of decorative panels, this die-casting method will not only cause a large number of burrs to be attached to the die mouth after the plate is die-cast, but also the burrs at the inclined parts of the bending parts of the decorative panels cannot be cleaned after the automobile decorative panels are die-cast, resulting in too many burrs on the rough plate surface of the automobile decorative panels, the edge lines at the bending parts of the decorative panels are worn and blurred, and the decorative panels cannot be used, which seriously affects the normal processing of the stamping mechanism for automobile decorative panels;

[0005] Secondly, when the punching blade of the punching machine is used to punch and produce automobile decorative panels for a long time, residual burrs will accumulate on the punching blade. When the punching machine performs secondary punching of the automobile decorative panels, the residual burrs on the punching blade will interfere with the punching of the automobile decorative panels, resulting in burrs all over the stamping surface of the decorative panels, which will lead to deformation of the automobile decorative panels, damage to the automobile decorative panels, and severe wear of the punching blade.

[0053] The prior art uses a punching machine to directly punch automobile decorative panels, which not only causes excessive burrs on the surface of the automobile decorative panels, affecting the aesthetics and usability of the automobile decorative panels, but also causes a large number of burrs to be attached to the surface of the punching tool head after punching. As a result, during the secondary punching of automobile panels, there are too many punching burrs on the automobile panels, which causes stamping deformation, wastes a lot of energy consumption, reduces the production efficiency of automobile panels, and makes the automobile decorative panels unusable after punching.The present application sets a square sliding plate 23 and a concave sliding plate 24. When in use, the output end of the cylinder 21 in the stamping assembly 2 is firstly extended downward by ventilation to drive the fixedly connected square sliding plate 23 to slide downward along the two column surfaces of the two column rods 22, and the square sliding plate 23 drives the four fixedly connected spring telescopic sleeves 26 to slide downward, and at the same time, the square sliding plate 23 drives the two fixedly connected column rods 27 to slide downward, and the square sliding plate 23 drives the fixedly connected universal floating shaft 25 to slide downward, so that the universal floating shaft 25 drives the slidingly connected T-shaped hollow mold plate 211 to slide downward, and then the T-shaped hollow mold plate 211 drives the two fixedly connected telescopic boxes 28 to slide downward, and further The two telescopic boxes 28 drive the fixedly connected blade 1 215 and blade 2 216 to slide downward, and the two telescopic boxes 28 drive the fixedly connected impact stress spring 210 and impact cutter head 29 to slide downward, and synchronously make the square sliding plate 23 push the fixedly connected rack 213 to move downward, and then when the tooth groove at the bottom of the rack 213 moves to contact with the tooth groove on the right side of the gear 214, then under the driving force of the continuous downward movement of the rack 213, the tooth groove at the bottom of the rack 213 and the gear 214 perform clockwise meshing and rotational motion, thereby indirectly driving the gear 214 to mesh with the transmission rack 1 212 to move upward, and then the rack 1 212 drives the fixedly connected concave sliding plate 24 along the upward movement of the column 1 22 The cylindrical surface slides upward, and when the bottom of the rack 1 212 moves toward the direction of the rack 213 to be flush with the position of the gear 214, the top of the concave sliding plate 24 is flush with the bottom of the T-shaped hollow mold plate 211, and then the two telescopic boxes 28 at the bottom of the T-shaped hollow mold plate 211 are flush with the top of the concave sliding plate 24, so that the impact cutter head 29 at the bottom of the two telescopic boxes 28 can perform a stamping and cutting operation on the automobile decorative panel clamped in the concave sliding plate 24 to complete the die-casting of the automobile decorative panel. At the same time, under the impact force of the two telescopic boxes 28 toward the concave sliding plate 24, after the impact cutter head 29 impacts the cut surface of the automobile decorative panel, the top of the impact cutter head 29 can squeeze the impact stress spring 210 toward the telescopic box The inner wall of the telescopic box 28 shrinks, and the residual burrs attached to the blade surface of the impact cutter head 29 can be shrunk into the inner wall together. At this time, the lubricant in the inner wall of the telescopic box 28 can contact the blade surface of the impact cutter head 29 after shrinking. Under the action of the continuous shrinkage force of the impact cutter head 29, the blade 1 215 and the blade 2 216 are closely attached to the side wall of the impact cutter head 29, and the burr parts on the side wall of the impact cutter head 29 are scraped off after lubrication. The burr removal process on the surface of the impact cutter head 29 can be completed, and the residual burrs can be prevented from interfering with the blade of the impact cutter head 29 when the car decorative panel is stamped for the second time, and the adhesion of the residual burrs can be reduced, and the stamping activity of the two impact cutter heads 29 can be enhanced, so as to ensure the normal lubrication stamping process of the car decorative panel. ;

[0054] It should be noted that the lubrication and burr cleaning operation of the impact cutter head 29 requires the internal lubricant to be transferred to the two telescopic boxes 28 through the lubricant box 61 and the drainage tube 62, and then a synchronous contraction lubrication and burr flushing process is performed to complete the burr cleaning of the cutting edges of the two impact cutter heads 29.

[0055] The present invention provides a square sliding plate 23, a concave sliding plate 24, an impact cutter head 29 and a blade 1 215. During the process of the square sliding plate 23 and the concave sliding plate 24 sliding up and down, the blade edge of the impact cutter head 29 can be driven to retract toward the inside of the telescopic box 28 after stamping the automobile decorative panel. After contacting with the lubricant in the telescopic box 28, the blade 1 215 and the blade 2 216 can scrape the burrs from the blade edge of the impact cutter head 29 by lubrication, thereby avoiding interference of residual burrs on the blade edge of the impact cutter head 29 during secondary stamping of the automobile decorative panel, reducing the adhesion of the residual burrs, and enhancing the flexibility of the impact cutter head 29, thereby ensuring the normal progress of the lubrication stamping process of the automobile decorative panel.

[0056] like Figure 2 , Figure 5 and Fig. 9 As shown, the interior of the stamping assembly 2 is provided with a burr scraping assembly 3, and the burr scraping assembly 3 includes a motor 31, and the motor 31 is fixedly connected to the inner top wall of the T-shaped hollow mold plate 211, and the output shaft end of the motor 31 is fixedly connected to a transmission wheel 33, and the bottom of the transmission wheel 33 is rotatably connected to the T-shaped hollow mold plate 211. The burr scraping assembly 3 is used to perform a rotary mobile scraping operation on the pressing burr of the automobile decorative plate after stamping, and is linked with the universal floating shaft 25 and the T-shaped hollow mold plate 211 included in the stamping assembly 2 to change the inclination angle to scrape the burrs on the inclined surface of the automobile decorative plate;

[0057] The outer surface of the transmission wheel 1 33 is transmission-connected with a transmission belt 1 34, and one end of the transmission belt 1 34 away from the transmission wheel 1 33 is transmission-connected with a transmission wheel 2 35, and the inner wall of the T-shaped hollow mold plate 211 is rotationally connected with the transmission wheel 2 35, and the outer surface of the transmission belt 1 34 is fixedly connected with a T-shaped telescopic rod 36, and the bottom of the T-shaped telescopic rod 36 is fixedly connected with a telescopic scraper 37, and the telescopic part of the telescopic scraper 37 is fixedly connected with a blade 3 310;

[0058] The inner bottom wall of the T-shaped hollow mold plate 211 is provided with a slideway 32, the top of the T-shaped telescopic rod 36 penetrates and is slidably connected to the slideway 32, the inner wall of the T-shaped telescopic rod 36 is fixedly connected with a spring 1 38, and the inner wall of the telescopic scraper 37 is fixedly connected with a spring 2 39.

[0059] By setting the burr scraping component 3, when in use, while the stamping component 2 continues to move downward, the T-shaped hollow mold plate 211 is indirectly driven to drive the burr scraping component 3 to move downward. When the T-shaped hollow mold plate 211 moves downward to be flush with the pressure opening of the automobile decorative panel in the concave clamping plate 2 51, the bottom of the telescopic scraper 37 can be flush with the bottom of the automobile decorative panel, and the telescopic scraper 37 is indirectly driven to push the T-shaped telescopic rod 36 to squeeze the spring 1 38 to retract upward. When the telescopic scraper 37 moves toward the T-shaped hollow mold plate 211 to be flush with the pressure opening of the automobile decorative panel, the output shaft of the motor 31 can be powered on to rotate clockwise, and the burr scraping component 3 starts to work. Then the output shaft of the motor 31 can rotate to drive the fixed The connected transmission wheel 1 33 rotates clockwise, thereby causing the transmission wheel 1 33 to rotate and drive the transmission wheel 2 35 connected to one end of the transmission belt 1 34 to rotate clockwise, and at the same time, the transmission belt 1 34 drives the T-shaped telescopic rod 36 fixedly connected to the outer surface to move clockwise along the trajectory of the slideway 1 32, and the T-shaped telescopic rod 36 drives the fixedly connected telescopic scraper 37 to move clockwise along the trajectory of the slideway 1 32. At the same time, under the influence of the interaction force between the telescopic scraper 37 and the pressure mouth of the automobile decorative panel, the blade of the telescopic scraper 37 can squeeze the spring 2 39 to contract inward when scraping burrs, thereby causing the blade 3 310 fixedly connected to the telescopic part of the telescopic scraper 37 to cut the telescopic scraper 37. The burrs attached to the mouth can be scraped off, and the lubrication of the blade after the burrs are scraped off can be completed under the action of lubricant. At this time, the telescopic scraper 37 can scrape off the burrs in the range of the pressure mouth of the automobile decorative panel after the stamping component 2 is stamped according to the inclined support position of the T-shaped hollow mold plate 211, thereby improving the aesthetics of the automobile decorative panel after stamping and ensuring the normal progress of the burr removal and stamping process of the automobile decorative panel. If the automobile decorative panel needs to be cleaned of the burrs on the inclined surface, after the burrs on the parallel pressure mouth of the automobile decorative panel are cleaned, the clockwise rotation of the motor 31 is stopped, and the square sliding plate 23 can be driven by the force of the continuous movement of the concave sliding plate 24, which can indirectly drive the T-shaped hollow mold plate 211 to drive The burr scraping assembly 3 and the two telescopic boxes 28 move toward the concave sliding plate 24. When the bottoms of the two telescopic boxes 28 are flush with the left inclined surface of the automobile decorative panel, the cylinder 21 can indirectly drive the top of the T-shaped hollow mold plate 211 to rotate clockwise along the bottom spherical surface of the universal floating shaft 25 for a certain arc, and after the T-shaped hollow mold plate 211 drives the burr scraping assembly 3 to rotate clockwise for a certain arc, the motor 31 can be powered on again to rotate the output shaft clockwise, indirectly driving the telescopic scraper 37 to scrape the burrs at the inclined pressure mouth of the automobile decorative panel, further enhancing the cleaning power of the telescopic scraper 37 on automobile decorative panels with different inclined surfaces, and ensuring the normal progress of the burr-free stamping process of the automobile decorative panels.

[0060] It should be noted that when the retractable scraper 37 cleans the burrs on the inclined surface, it is necessary to adjust the inclination angle of the T-shaped hollow mold plate 211 and maintain the posture according to the inclination of the inclined surface of the automobile decorative panel, so as to support the retractable scraper 37 to scrape off the burrs on the inclined surface pressure portion to achieve the burr removal process.

[0061] The burr scraping component 3 provided in this scheme can indirectly drive the telescopic scraper 37 to scrape the burrs at the pressing mouth of the automobile decorative panel after stamping under the action of the continuous rotation transmission of the transmission belt 34, thereby further improving the aesthetics of the automobile decorative panel after stamping, ensuring the normal progress of the burr removal stamping process of the automobile decorative panel, and can indirectly drive the T-shaped hollow mold plate 211 and the telescopic scraper 37 to adjust a flip arc according to the different inclination degrees of the pressing mouth of the automobile decorative panel, so that the telescopic scraper 37 can scrape the burrs at the pressing mouth of different inclinations, further enhance the cleaning power of the telescopic scraper 37 on automobile decorative panels with different inclinations, reduce the corrosion of the inclined burrs on the automobile decorative panels, and ensure the normal progress of the burr-free stamping process of the automobile decorative panels.

[0062] like Fig. 9 , Fig.10 and Fig.13 As shown, a wiping assembly 4 is provided at the bottom of the burr scraping assembly 3, and the wiping assembly 4 is used to perform a mobile wiping operation to clean the residual burrs and dust on the pressure mouth of the automobile decorative panel after the burrs are scraped off by the telescopic scraper 37;

[0063] The wiping assembly 4 includes a square brush 41 , and the square brush 41 is fixedly connected to the bottom of the T-shaped telescopic rod 36 .

[0064] By setting up the wiping component 4, when working, when the blade edge of the telescopic scraper 37 is aligned with the burr edge line of the pressure mouth of the automobile decorative panel, the brush fibers at the bottom of the square brush 41 in the wiping component 4 can be tightly attached to the board surface of the burr part of the pressure mouth of the automobile decorative panel under the squeezing and contraction action of the T-shaped telescopic rod 36, and under the action of the moving force of the telescopic scraper 37 that continues to scrape the burrs, the square brush 41 can indirectly move closely and wipe and clean the burrs as the telescopic scraper 37 scrapes the burrs and loosens the parts, thereby ensuring that the telescopic scraper 37 can wipe the pressure mouth surface after scraping the burrs, keep the cleanliness of the pressure mouth surface, reduce the secondary interference of the scraped burrs on the automobile decorative panel, and ensure the normal progress of the automobile decorative panel cleaning process.

[0065] like Figures 1 to 3 , Fig.11 As shown, a clamping and flipping assembly 5 is provided at the bottom of the stamping assembly 2, and the clamping and flipping assembly 5 is used to clamp automobile decorative panels of different sizes and perform double-sided flipping operations on the clamped decorative panels;

[0066] The clamping and flipping assembly 5 includes a second concave clamping plate 51, which is rotatably connected between the inner walls of the concave sliding plate 24, and a concave movable plate 52 is slidably connected to the right side of the second concave clamping plate 51, and a spiral rod 53 is rotatably connected to the right side of the concave movable plate 52, and the outer surface of the spiral rod 53 penetrates and is threadedly connected to the second concave clamping plate 51;

[0067] The concave sliding plate 24 is slidably sleeved with two buckles 54 on one side close to the concave clamping plate 2 51. The two buckles 54 are symmetrically distributed. One end of the two buckles 54 away from the concave sliding plate 24 is slidably sleeved with the concave clamping plate 2 51. One end of the two buckles 54 away from the concave clamping plate 2 51 is fixedly connected with a spring 3 55. One end of the spring 3 55 away from the buckle 54 penetrates and is fixedly connected with the concave sliding plate 24.

[0068] A T-shaped limit rotating rod 56 is fixedly connected to one side of the concave clamping plate 21, and one end of the T-shaped limit rotating rod 56 passes through the concave sliding plate 24 and is rotatably connected to the concave sliding plate 24. A slideway 2 59 is provided on the side of the body 1 close to the T-shaped limit rotating rod 56, and the end of the T-shaped limit rotating rod 56 close to the body 1 is slidably connected to the slideway 2 59. A triangular limit block 1 57 is penetrated and fixedly connected to the side of the body 1 close to the slideway 2 59, and the triangular block part of the triangular limit block 1 57 is flush with the inner track of the slideway 2 59. The bottom of the triangular limit block 1 57 passes through and is rotatably connected to a triangular limit block 2 58. A torsion spring 510 is fixedly connected to the side of the triangular limit block 2 58 close to the slideway 2 59, and the end of the torsion spring 510 away from the triangular limit block 2 58 is fixedly connected to the triangular limit block 1 57.

[0069] By setting the clamping and flipping assembly 5, when working, one side of the pre-die-cast automobile decorative panel can be manually placed on the left clamping position of the concave clamping plate 2 51, and then the screw rod 53 threadedly connected to one side of the concave clamping plate 2 51 can be manually rotated clockwise, so that the screw rod 53 in the clamping and flipping assembly 5 pushes the rotatably connected concave movable plate 52 to move toward the left clamping position of the concave clamping plate 2 51. When the concave movable plate 52 moves toward the left clamping position of the concave clamping plate 2 51 until it contacts the other side of the automobile decorative panel, the screw rod 53 stops rotating. At this time, the concave clamping plate 2 51 and the concave movable plate 52 complete the clamping and fixing operation of the automobile decorative panel, thereby avoiding the instability of the automobile decorative panel during stamping, and at the same time enhancing the clamping and fixing effect of automobile decorative panels of different sizes, ensuring the normal progress of the stable stamping process of the automobile decorative panel.

[0070] If there are still residual burrs attached to the corners of the reverse side of the plate after the stamping burrs on the automobile decorative plate are cleaned, it is necessary to turn the automobile decorative plate over to clean the burrs. When the concave sliding plate 24 slides along the downward column surface of the column rod 1 22 toward the bottom of the body 1, the rotatably connected T-shaped limit rotating rod 56 is simultaneously driven to slide downward along the inner track of the slideway 2 59, and the T-shaped limit rotating rod 56 drives the fixedly connected concave clamping plate 2 51 to slide downward, and then the concave sliding plate 24 indirectly drives the two fixedly connected springs 3 55 and the two buckles 54 to slide downward. When the concave sliding plate 24 moves downward to the position aligned with the concave sliding plate 24, the concave sliding plate 24 is moved downward to the position aligned with the concave sliding plate 24. When the top of the triangular stop block 1 57 is flush, under the action of the continuous downward movement of the concave sliding plate 24, the bottom of the T-shaped stop rod 56 slides downward along the edge of the triangular stop block 1 57, and the top of the T-shaped stop rod 56 rotates clockwise with the triangular stop block 1 57 as the rotation center, and slides downward along the inner track of the second slideway 59, further making the T-shaped stop rod 56 indirectly drive the concave clamping plate 2 51 and the spiral rod 53 and the concave movable plate 52 to rotate clockwise, thereby completing the flipping of the automobile decorative panel, and under the action of the flipping force of the concave clamping plate 2 51, the concave clamping plate 2 51 can be turned. The two buckles 54 are pushed to squeeze the spring three 55 to shrink into the concave sliding plate 24. When the bottom of the T-shaped limit rod 56 moves toward the bottom of the body 1 to be flush with the position of the triangular limit block 2 58, the concave sliding plate 24 continues to move toward the bottom of the body 1, so that the T-shaped limit rod 56 pushes the triangular limit block 2 58 to squeeze the torsion spring 510 to flip into the slideway 2 59, so that the bottom of the flipped T-shaped limit rod 56 slides into the slideway 2 59 again. When the T-shaped limit rod 56 moves to be flush with the bottom of the slideway 2 59, the cylinder 21 stops venting and stops the contraction operation, and the car decoration is completed. The plate is turned over. If there are still residual burrs on the turned over automobile decorative plate that have not been cleaned, the above steps can be cyclically operated to clean it, which further enhances the punching machine's ability to perform double-sided punching and clean burrs on automobile decorative plates of different shapes, ensuring that the automobile decorative plates after punching are free of foreign matter and can be used normally. After all automobile decorative plates are punched and cleaned, the manual knob spiral rod 53 rotates counterclockwise to drive the concave movable plate 52 to move in the direction of the spiral rod 53. When the concave movable plate 52 moves to a position where the automobile decorative plate can be released, the spiral rod 53 is stopped from rotating, and the automobile decorative plate after punching and cleaning is taken out to complete the punching process.

[0071] Instructions for use: When the present invention is used, the machine body 1 is first placed on a preset workbench, and then the pre-punched automobile decorative panel is clamped in the clamping and flipping assembly 5, and then the lubricant liquid is injected into the lubricant tank 61 in the lubricant supply assembly 6, and the lubricant tank 61 guides the injected lubricant liquid to the drainage pipe 62 that penetrates and is fixedly connected to the bottom through the built-in diversion pump, and then under the drainage effect of the drainage pipe 62, the lubricant liquid in the drainage pipe 62 can be transported to two hoses 1 63 and hose 2 64, and then under the effect of the lubricant supply diversion and lubricant supply of the lubricant supply assembly 6, the lubricant liquid in the drainage pipe 62 can be transported to two hoses 1 63 and hose 2 64. The lubricant supply component 6 can provide stable lubricant liquid support for the stamping component 2 and the burr scraping component 3 to clean the burrs, ensuring the normal progress of the stamping process of the automobile decorative panel. After the lubricant liquid in the two telescopic boxes 28, the telescopic scraper 37 and the lubricant box 61 are filled, the liquid filling operation is stopped, and then the stamping component 2 is driven to drive the burr scraping component 3 to move toward the automobile decorative panel clamped in the clamping and flipping component 5. When the stamping component 2 moves to a flush position with the clamping and flipping component 5, the automobile decorative panel inside the clamping and flipping component 5 can be stamped, and the impact cutter head can be completed simultaneously. 29 lubricates and cleans the burrs attached to the surface. At the same time, according to the distribution of burrs after stamping of the automobile decorative panel, continue to press down to adjust the inclination angle of the stamping component 2 and the burr scraping component 3, so that the burr scraping component 3 can perform mobile scraping treatment on the burrs on the different inclined panels, so that the telescopic scraper 37 can scrape the burrs on the pressure mouth of different inclined surfaces. At the same time, the burr scraping component 3 can drive the wiping component 4 to rotate clockwise, and the wiping component 4 can perform mobile wiping and cleaning treatment on the pressure mouth burrs loosened by the burr scraping component 3, thereby reducing the damage caused by the loosened burrs to the automobile decorative panel. Secondary interference ensures the normal progress of the automobile decorative panel cleaning process. At this point, after the stamping component 2 and the burr scraping component 3 complete the burr cleaning of the automobile decorative panel, the stamping component 2 and the clamping and flipping component 5 can be separated, and then the automobile decorative panel in the clamping and flipping component 5 can be taken out. If the automobile decorative panel needs to be turned over for cleaning, it is necessary to make the clamping and flipping component 5 drive the clamped automobile decorative panel to flip over while descending after the first stamping of the clamping and flipping component 5, and then start the cyclic cleaning operation. After all the automobile decorative panels are stamped and cleaned, the device can be stopped and the stamping is completed.
