Description

Technical Field

[0001] The utility model relates to the field of film punching, in particular to a combined film punching die. Background Art

[0002] Film punching is a processing technology that is mainly used to cut continuous film materials into single or multiple independent parts or shapes according to predetermined shapes and sizes. This technology is usually used in various industries that require precise cutting of film, such as electronic product manufacturing, automotive parts production, medical device manufacturing, packaging industry, etc. In the process of film punching, special punching machines or die-cutting machines are usually used. These machines are equipped with sharp blades or dies to cut the film according to the preset pattern or shape. Film punching can achieve high-precision cutting to ensure that the size and shape of each part or shape meet the design requirements. Among them, film punching dies are mainly used for punching film. Such dies usually have the characteristics of high precision and complex shapes to adapt to the special physical and chemical properties of film materials. Film materials may have low density, good chemical stability, electrical insulation, thermal insulation, sound insulation, wear resistance and self-lubrication. Therefore, film punching dies need to take these factors into special consideration when designing and manufacturing to ensure accuracy and product quality during punching.

[0003] Some films have adhesive glue, especially when it is not fully cured or sticky. If these glues remain on the cutter head during the punching process, they may adhere to the surface of the cutter head, causing the cutter head to become blunt or form scale. As the punching process proceeds, if the glue adhering to the cutter head continues to accumulate, these scales will increase the friction between the cutter head and the film, thereby accelerating the wear of the cutter head. The glue deposits on the cutter head will affect the cutting accuracy and edge quality. The scale will cause the cutter head to be unable to accurately cut the film, and there may be problems such as continuous cutting, off-center cutting or burrs. In some cases, if the glue is more viscous or the amount is large, they may block the gaps or openings of the cutter head, causing the cutter head to malfunction.

[0004] Traditional film punching dies cannot achieve self-cleaning function, workers need to clean the dies regularly, and the machine needs to be shut down for cleaning, which affects the processing progress and leads to a reduction in production line output. Therefore, it is necessary to propose a combined film punching die to solve the above problems. Utility Model Content

[0014] Technical effects and advantages of the utility model:

[0015] The device is provided with a nozzle. When the first punching and shearing head and the second punching and shearing head perform punching and shearing alternately, the inner wall of the punching and shearing groove that is not in operation will be cleaned. During the punching and shearing process, the cleanliness of the inner wall of the punching and shearing groove is ensured to prevent the glue on the glue film from adhering to the inner wall of the punching and shearing groove. Long-term punching and shearing work will damage the punching and shearing groove and the punching and shearing heads. Therefore, the glue adhering to the inner wall of the punching and shearing groove can be automatically cleaned during work, realizing the function of self-cleaning while working. There is no need to stop the machine regularly to clean the mold, thereby ensuring the accuracy of the mold under long-term use.

[0016] The device performs alternate punching of the first punching head and the second punching head. Since the film has ductility and certain elasticity, the conventional unloading method easily causes the film to adhere to the inside of the punching groove. Therefore, the first punching head and the second punching head work alternately to simultaneously drive the gas flow and the sliding plate to generate a driving force so that the punched film can be quickly pushed out of the punching groove to avoid material accumulation.

[0017] The device utilizes the pressure of the punching machine to drive alcohol to spray on the inner wall of the punching and shearing groove. Alcohol can make most of the adhesive lose its effect through chemical reaction, making it easier to be cleaned by the sponge board. The sponge board can not only clean the inner wall of the punching and shearing groove, but also prevent the alcohol from staying on the inner wall of the punching and shearing groove for a long time. Moreover, when the sliding plate is pressed down, the alcohol inside the sponge board can be squeezed back through the nozzle and the liquid inlet pipe to the inside of the storage box. The sliding plate can scrape off the residual adhesive on the inner wall of the punching and shearing groove, thereby improving the integrity of the punching and shearing head, and the alcohol can also play a certain lubricating role.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides Figure 1-Figure 6 A combined film punching mold shown in the figure comprises a punching base 1, a movable plate 2 is provided above the punching base 1, a U-shaped plate 23 is fixedly installed on the upper surface of the movable plate 2, two symmetrical fixed plates 3 are provided above the movable plate 2, a plurality of second punching heads 5 and a first punching head 4 are provided inside the movable plate 2, sliding columns 7 are fixedly installed at the four corners of the upper surface of the punching base 1, a hard spring 71 is movably sleeved at the lower end of the sliding column 7, the movable plate 2 is movably sleeved on the sliding column 7, the two fixed plates 3 are fixedly installed on the upper end of the sliding column 7, the two ends of the hard spring 71 are respectively fixedly installed on the punching base 1 and the movable plate 2, a plurality of evenly distributed punching shear heads 41 are fixedly installed at the bottom ends of the second punching shear head 5 and the first punching shear head 4, and a plurality of punching shear grooves 11 corresponding to the punching shear heads 41 are opened on the upper surface of the punching base 1.

[0027] A first slot body 22 corresponding to the first punching head 4 is provided on the inner and outer surfaces of the movable plate 2, and a plurality of second slot bodies 32 corresponding to the first punching head 4 are provided on the side where the two fixed plates 3 are close to each other. The plurality of second punching heads 5 and the first punching heads 4 are arranged alternately, and the second punching heads 5 and the first punching heads 4 are provided with matching parts 43 on both sides. The inner sliding card of the punching base 1 is provided with a sliding plate 12, and a sponge plate 13 is fixedly installed on the lower surface of the sliding plate 12. A first spring telescopic rod 16 is embedded in the middle position of the inner bottom surface of the punching groove 11, and the top end of the first spring telescopic rod 16 is fixedly installed in the middle of the lower surface of the sliding plate 12. A plurality of nozzles 14 are embedded in the inner bottom surface of the punching base 1, and a plurality of liquid inlet pipes 15 corresponding to the punching groove 11 are fixedly installed on the lower surface of the punching base 1, and the liquid inlet pipes 15 are connected to the corresponding nozzles 14. A storage box 6 is fixedly installed on the lower surface of the punching base 1, and the interior of the storage box 6 is filled with alcohol, and the pipe of the liquid inlet pipe 15 extends to the inner bottom end of the storage box 6.

[0028] In actual use, the external stamping component is connected to the U-shaped plate 23, and then the film passes through the upper surface of the punching base 1. As the external stamping component drives, the U-shaped plate 23 drives the movable plate 2 to descend. At this time, the movable plate 2 will drive the first punching head 4 to descend, and the second punching head 5 will be stuck by the fixed plate 3 and will not move. Then, at this time, the punching shear head 41 slides and is stuck into a part of the punching groove 11, and then the film is punched. Then, the U-shaped plate 23 rises under the drive of the hard spring 71. At this time, the punching shear head 41 moves from the punching shear groove 11 to the punching shear groove 11. The inside of the groove 11 slides out, and the movable plate 2 is lifted to its original position. At this time, the movable plate 2 loses its grip on the first punching and shearing head 4 and clamps the second punching and shearing head 5. At this time, the first punching and shearing head 4 is clamped by the fixed plate 3. Then, when the U-shaped plate 23 descends again, it will drive the second punching and shearing head 5 to descend to produce a punching and shearing effect on the film. When the punching and shearing head 41 on the second punching and shearing head 5 enters the inside of the punching and shearing groove 11, the remaining punching and shearing films inside the punching and shearing heads 41 will be blown out of the punching and shearing groove 11, and at the same time, the remaining punching and shearing grooves 11 will have a cleaning effect.

[0029] When the first punching and shearing head 4 descends, it will drive the punching and shearing head 41 to enter a part of the punching and shearing groove 11. Because the texture of the adhesive film is relatively soft and has a certain degree of adhesiveness, the punching and shearing head 41 and the punching and shearing groove 11 need to have high matching accuracy to achieve punching and shearing. The high matching accuracy means that when the punching and shearing head 41 enters the punching and shearing groove 11, the punching and shearing head 41 will push the sliding plate 12 to compress the first spring telescopic rod 16, and the interior of the punching and shearing groove 11 will be relatively sealed. The air pressure inside the punching and shearing groove 11 is compressed and enters the interior of the storage box 6 along with the nozzle 14 and the liquid inlet pipe 15. The interior of the storage box 6 is also relatively sealed. Therefore, when the compressed air enters the interior of the storage box 6, the alcohol inside the storage box 6 will entrain the air into the remaining punching and shearing grooves 11, and the sliding plate 12 fits with the inner wall of the punching and shearing groove 11 to form a relatively sealed chamber. The sliding plate 12 will be pushed upward, and during this process, the nozzle 14 sprays mist alcohol, which will adhere to the inner wall of the punching and shearing groove 11 to clean the adhesive on the top. The sliding plate 12 is pushed upward to push the internal punched and sheared film out of the punching and shearing groove 11. When the sliding plate 12 moves upward, it will drive the sponge plate 13 to rise. At this time, the first spring telescopic rod 16 is stretched. When the punching and shearing head 41 slides out of the punching and shearing groove 11, the sliding plate 12 will return to its initial position under the action of the internal air pressure and the first spring telescopic rod 16 to facilitate the next cycle of work. When the sliding plate 12 is pushed downward, the sponge plate 13 will clean the alcohol and adhesive on the inner wall of the punching and shearing groove 11 to prevent the adhesive from adhering to the inner wall of the punching and shearing groove 11 for a long time and causing damage to the punching and shearing head 41.

[0030] The glue on the film is sticky, especially when it is not fully cured or sticky. If these glues remain on the cutter head during the punching process, they may adhere to the surface of the cutter head, causing the cutter head to become blunt or form deposits. As the punching process progresses, if the glue adhering to the cutter head continues to accumulate, these deposits will increase the friction between the cutter head and the film, thereby accelerating the wear of the cutter head. The glue deposits on the cutter head will affect the cutting accuracy and edge quality. The deposits will cause the cutter head to be unable to accurately cut the film, and there may be problems such as continuous cutting, off-cut cutting, or burrs. In some cases, if the glue is more viscous or the amount is large, they may block the gaps or openings of the cutter head, causing the cutter head to not work properly.

[0031] Therefore, the device is provided with a nozzle 14. When the first punching and shearing head 4 and the second punching and shearing head 5 perform alternate punching and shearing, the inner wall of the punching and shearing groove 11 that is not in operation will be cleaned, so as to ensure the cleanliness of the inner wall of the punching and shearing groove 11 during the punching and shearing process, and prevent the glue on the adhesive film from adhering to the inner wall of the punching and shearing groove 11. Long-term punching and shearing work will damage the punching and shearing groove 11 and the punching and shearing head 41. Therefore, the glue adhering to the inner wall of the punching and shearing groove 11 can be automatically cleaned during work, so as to realize the function of self-cleaning while working, and there is no need to stop the mold regularly for cleaning, so as to ensure the accuracy of the mold under long-term use.

[0032] The matching component 43 includes a T-shaped slider 431. Both sides of the first punching and shearing head 4 and the second punching and shearing head 5 are provided with a T-shaped slide groove 42 corresponding to the T-shaped slider 431. The T-shaped slider 431 is slidably clamped in the interior of the T-shaped slide groove 42. The upper and lower sides of the matching component 43 are respectively fixedly installed with a second spring telescopic rod 432 and a third spring telescopic rod 433. The ends of the second spring telescopic rod 432 and the third spring telescopic rod 433 that are away from each other are respectively fixedly installed with a first slide bar 434 and a second slide bar 435. The first slide bar 434 is movably clamped in the interior of the second slot body 32. The second slide bar 435 The movable card 35 is arranged inside the first slot body 22, the second slot body 32 is formed by the fourth slot 321, the fifth slot 322, and the sixth slot 323 being connected in sequence, the fourth slot 321 is connected to the outside, the first slot body 22 is formed by the first slot 221, the second slot 222, and the third slot 223 being connected in sequence, the first slot 221 is connected to the outside, the second slot 222 and the fifth slot 322 are inclined, a plurality of second card blocks 31 are fixedly installed between the two fixed plates 3, and a plurality of first card blocks 21 are fixedly installed on the inner walls of both sides of the movable plate 2 at positions corresponding to the second card blocks 31.

[0033] When the device is in the initial position, the second slide bar 435 is located inside the third through slot 223. At this time, the matching component 43 is stuck in the first slot body 22, and the fixed plate 3 loses the force on the matching component 43, so that the matching component 43 and the first punching and shearing head 4 will move with the movement of the movable plate 2. At the same time, the second punching and shearing head 5 is stuck by the fixed plate 3. When the punching machine performs an up and down cycle, the movable plate 2 rises, thereby driving the first slide bar 434 to enter the fourth through slot 321. Under the continuous push of the movable plate 2, the fourth through slot 321 contacts the fifth through slot 322. Under the continuous push, the first slide bar 434 will be pushed to slide along the fifth through slot 322 to the inside of the sixth through slot 323. At this time, the second slide bar 435 will also slide out from the inside of the third through slot 223 due to the pushing force and slide along The second through slot 222 slides to the position of the first through slot 221, and the second spring telescopic rod 432 and the third spring telescopic rod 433 are used to offset the longitudinal force during sliding, so that the first slide bar 434 and the second slide bar 435 can move horizontally smoothly. At this time, the matching component 43 and the first punching and shearing head 4 are stuck by the fixed plate 3. At the same time, the fixed plate 3 loses the force on the second punching and shearing head 5. The movable plate 2 can drive the second punching and shearing head 5 to perform the above-mentioned movement, thereby realizing the alternating punching and shearing work of the first punching and shearing head 4 and the second punching and shearing head 5, so that when one of the first punching and shearing head 4 and the second punching and shearing head 5 is working, it can clean and unload the remaining unworked punching and shearing grooves 11. The material pushed out of the punching and shearing grooves 11 can be unloaded using a fan or other unloading methods, which is not the protection object of the present utility model, so it will not be described here.

[0034] Working principle: Connect the external stamping component with the U-shaped plate 23, and then pass the film through the upper surface of the punching base 1. With the drive of the external stamping component, the U-shaped plate 23 drives the movable plate 2 to descend. At this time, the movable plate 2 will drive the first punching head 4 to descend, and the second punching head 5 will be stuck by the fixed plate 3 and will not move. Then, the punching shear head 41 slides and enters a part of the punching groove 11 to punch the film. Then, the U-shaped plate 23 rises under the drive of the hard spring 71. At this time, the punching shear head 41 moves from the punching shear groove 11 to the upper surface of the punching base 1. The inside of the groove 11 slides out, and the movable plate 2 is lifted to its original position. At this time, the movable plate 2 loses its grip on the first punching and shearing head 4 and clamps the second punching and shearing head 5. At this time, the first punching and shearing head 4 is clamped by the fixed plate 3. Then, when the U-shaped plate 23 descends again, it will drive the second punching and shearing head 5 to descend to produce a punching and shearing effect on the film. When the punching and shearing head 41 on the second punching and shearing head 5 enters the inside of the punching and shearing groove 11, the remaining punching and shearing films inside the punching and shearing heads 41 will be blown out of the punching and shearing groove 11, and at the same time, the remaining punching and shearing grooves 11 will have a cleaning effect.

[0035] When the device is in the initial position, the second slide bar 435 is located inside the third through slot 223. At this time, the matching component 43 is stuck in the first slot body 22, and the fixed plate 3 loses the force on the matching component 43, so that the matching component 43 and the first punching and shearing head 4 will move with the movement of the movable plate 2. At the same time, the second punching and shearing head 5 is stuck by the fixed plate 3. When the punching machine performs an up and down cycle, the movable plate 2 rises, thereby driving the first slide bar 434 to enter the fourth through slot 321. Under the continuous push of the movable plate 2, the fourth through slot 321 contacts the fifth through slot 322. Under the continuous push, the first slide bar 434 will be pushed to slide along the fifth through slot 322 to the inside of the sixth through slot 323. At this time, the second slide bar 43 5 will also slide out from the inside of the third through slot 223 due to the pushing force and slide along the second through slot 222 to the position of the first through slot 221. The second spring telescopic rod 432 and the third spring telescopic rod 433 are used to offset the longitudinal force during sliding, so that the first slide bar 434 and the second slide bar 435 can move horizontally smoothly. At this time, the matching component 43 and the first punching and shearing head 4 are stuck by the fixed plate 3. At the same time, the fixed plate 3 loses the force on the second punching and shearing head 5. The movable plate 2 can drive the second punching and shearing head 5 to perform the above-mentioned movement, thereby realizing the alternating punching and cutting work of the first punching and shearing head 4 and the second punching and shearing head 5, so that when one of the first punching and shearing head 4 and the second punching and shearing head 5 is working, it can clean and unload the remaining unworked punching and shearing grooves 11.

[0036] When the first punching and shearing head 4 descends, it will drive the punching and shearing head 41 to enter a part of the punching and shearing groove 11. Because the texture of the adhesive film is relatively soft and has a certain degree of adhesiveness, the punching and shearing head 41 and the punching and shearing groove 11 need to have high matching accuracy to achieve punching and shearing. The high matching accuracy means that when the punching and shearing head 41 enters the punching and shearing groove 11, the punching and shearing head 41 will push the sliding plate 12 to compress the first spring telescopic rod 16, and the interior of the punching and shearing groove 11 will be relatively sealed. The air pressure inside the punching and shearing groove 11 is compressed and enters the interior of the storage box 6 along with the nozzle 14 and the liquid inlet pipe 15. The interior of the storage box 6 is also relatively sealed. Therefore, when the compressed air enters the interior of the storage box 6, the alcohol inside the storage box 6 will entrain the air into the remaining punching and shearing grooves 11, and the sliding plate 12 fits with the inner wall of the punching and shearing groove 11 to form a relatively sealed chamber. The sliding plate 12 will be pushed upward, and during this process, the nozzle 14 sprays mist alcohol, which will adhere to the inner wall of the punching and shearing groove 11 to clean the adhesive on the top. The sliding plate 12 is pushed upward to push the internal punched and sheared film out of the punching and shearing groove 11. When the sliding plate 12 moves upward, it will drive the sponge plate 13 to rise. At this time, the first spring telescopic rod 16 is stretched. When the punching and shearing head 41 slides out of the punching and shearing groove 11, the sliding plate 12 will return to its initial position under the action of the internal air pressure and the first spring telescopic rod 16 to facilitate the next cycle of work. When the sliding plate 12 is pushed downward, the sponge plate 13 will clean the alcohol and adhesive on the inner wall of the punching and shearing groove 11 to prevent the adhesive from adhering to the inner wall of the punching and shearing groove 11 for a long time and causing damage to the punching and shearing head 41.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
