Description

Technical Field

[0001] This invention belongs to the field of punch press feeders, specifically a fully automatic punch press feeder. Background Technology

[0002] A punch press feeder is an auxiliary device specifically designed for automated stamping production. It is used to precisely feed metal coils or sheets into the punch press die area at a set pitch and speed. It replaces manual feeding, significantly improving production safety and efficiency, ensuring feeding accuracy, and reducing material waste.

[0003] Common types include servo feeders, roller feeders, and pneumatic feeders, which can be combined with uncoilers and levelers to form automated production lines. They are widely used in stamping processes in industries such as electronics, hardware, and automobiles.

[0004] Traditional punch press feeders are often quite simple in function, usually just using rollers or other friction structures to feed the coiled material. However, the coiled material, especially when rolled into shape, is prone to residual oil film on the surface, making frictional transport difficult. In addition, the coiled material has the characteristic of being thicker in the middle and thinner at both ends in the width direction. This is an inherent defect of the calendering process. Insufficient contact with the rollers and uneven distribution of friction force can also lead to problems in the transport process. Once the automatic feeding fails, it can easily cause subsequent punch press operations to stop or malfunction, seriously affecting the production process.

[0005] Therefore, the present invention provides a fully automatic punch press feeder. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a fully automatic punch press feeder, including a servo take-up roller for winding raw materials, and a support frame for support is installed at the end of the servo take-up roller; it also includes a feed box, the front end of which has a through opening extending to the rear end, and the inner side of the feed box is sequentially provided with a feeding wheel set, a friction table, a punch, a drive table and a discharge wheel set, the punch including an upper punch plate and a lower punch plate for punching the edge of the raw material, and the drive table including a drive wheel adapted to the punching hole; This setup not only achieves stable coil feeding, delivering a steady and orderly coil to the punch press, but also addresses the challenge of friction feeding by pre-processing a row of drive holes through stamping. Direct drive is then used to stably advance the coil, improving its adaptability and practicality. Furthermore, the hole-driven mechanism ensures the drive wheel aligns with the hole each time it travels, forming a straight processing line. This guarantees the coil remains on the straight line between the drive wheel and the stamping part during transport. Each transmission process provides subtle correction, ensuring precise feeding. The friction table is located after the feed roller assembly. It can grind and clean the surface of the coiled material, removing some oil and burrs. This not only provides pretreatment for the stamping process of the punch press, but also significantly reduces the probability of scratches, dents, orange peel, and other defects on the surface of the stamped parts. After grinding and cleaning, the feed roller assembly and discharge roller assembly alone are still insufficient to transport the material for the punch press and drive table for punching and transport, thus saving energy. At the same time, grinding and cleaning also helps the punch press to operate smoothly.

[0008] Preferably, the feed roller assembly and the discharge roller assembly are located near the through-hole. The discharge roller assembly includes multiple rotatable and lifting transport rollers, which are divided into upper and lower groups. The feed roller assembly includes two power wheels, each with a lifting platform at both ends for driving the power wheels to rise and fall. The multiple lifting and rotating transport rollers are used to clamp the coil at the outlet end, providing some outward transport power to the coil. When the friction is sufficient, it is enough to transport the coil; when the friction is insufficient, it can still provide some guiding force to ensure that the coil is stably discharged from the through-hole. The feed roller assembly and the discharge roller assembly have the same function. The inner wall of the feeding box is equipped with a drive component for driving the transport rollers and the lifting platform to rise and fall, which can be a screw and nut mechanism.

[0009] Preferably, the stamping device includes an upper hydraulic platform and a lower support platform fixedly connected to each other. The bottom drive end of the upper hydraulic platform is fixedly connected to the upper stamping plate. The top of the lower support platform is equipped with a lifting arm that can be raised and lowered. The top of the lifting arm is fixedly connected to the lower stamping plate. The lower support platform is flush with the bottom of the coil material under the adjustment of the lifting arm to ensure that the coil material moves horizontally in the feeding box. Then, under the pressing of the lower stamping plate, it cooperates with the stamping parts at the bottom of the lower stamping plate to complete the equidistant opening of multiple holes.

[0010] Preferably, the drive platform includes a power platform, and a synchronous slide rail is installed on the side of the upper hydraulic platform near the power platform. The moving end of the synchronous slide rail is fixedly connected to the power platform. An electric slide rail is installed at the bottom of the lower support platform to drive the lower support platform to move horizontally. The electric slide rail drives the lower support platform to move horizontally, thereby moving the upper and lower stamping plates to the edge position where the coil needs to be punched, thus adapting to different punching requirements. The power platform moves synchronously with the upper hydraulic platform and is finely adjusted by the synchronous slide rail to ensure that the position of the drive wheel and the punching position are on a straight line.

[0011] Preferably, the power platform has a second lifting arm that can be raised and lowered internally. A drive motor is fixedly connected to the bottom of the second lifting arm, and the output end of the drive motor is fixedly connected to the drive wheel. The surface of the drive wheel is provided with multiple drive pins, and the surface of the drive wheel is provided with multiple connecting grooves for fixing the drive pins. The multiple connecting grooves are arranged in a ring at equal intervals. The shape of the drive pin can be pyramidal, and the tail is threaded to the connecting groove. The stamping hole can be circular or keyway-shaped to ensure that the hole is fully adapted to the drive pin, so that the positioning and transmission work can be carried out smoothly. During the adjustment stage, the drive wheel rises under the drive of the second lifting arm without contacting the coiled material. During the transmission stage, it is necessary to ensure that the drive wheel is in contact with the coiled material. A disassembly module can be integrated under the power platform to replace different drive pins for the drive wheel, thereby adapting to different coiled materials and holes.

[0012] Preferably, the bottom of the second lifting arm is slidably connected to an extension arm capable of lifting and lowering. A material plate is fixedly connected to the bottom of the extension arm. The surface of the material plate has a cutting groove that is flush with the position of the drive wheel. In order to ensure smooth transmission, a material plate is set at the bottom of the drive wheel to support the rolled material. The height can be freely adjusted under the drive of the extension arm. The cutting groove allows the drive pile passing through the hole to move.

[0013] Preferably, the surface of the lower stamping plate is equipped with a detachable replacement plate. The surface of the replacement plate is provided with a stamping groove that matches the upper stamping plate, and the surface of the lower stamping plate is provided with a positioning groove that matches the upper stamping plate. By using different replacement plates, different stamping parts can be adapted to stamp out holes of the required shape. The bottom of the upper stamping plate is also provided with a column that is inserted into the positioning groove during stamping to ensure the accuracy of stamping.

[0014] Preferably, a hollow groove is provided in the middle of the lifting arm, and the top of the hollow groove is connected to the bottom of the drive pile. An outwardly inclined material guide frame is installed on the outer side of the lower support platform. The material guide frame is connected to the hollow groove of the lifting arm. The waste generated by stamping slides downward through the middle of the drive pile and is finally discharged from the inclined material guide frame, ensuring that the continuous stamping operation is carried out smoothly.

[0015] Preferably, the friction table includes two lifting platforms that can be raised and lowered. A linkage wheel set is installed between the two lifting platforms. A friction belt is installed on the outer side of the linkage wheel set. The drive unit in the feeding box is also used to control the raising and lowering of the lifting platforms and the opening and closing of the two sets of friction belts, so as to fit rolls of material of different thicknesses. As the linkage wheel set is driven, the friction belt is driven to rotate, thereby rubbing and cleaning the surface of the roll. A spraying device can also be integrated on the outer side of the friction table to provide cleaning water for cleaning and to improve the cleaning effect.

[0016] Preferably, a power supply base is fixedly connected to the bottom of the feeding box, and arc-shaped buffer steps are fixedly connected to both sides of the feeding box. The buffer steps are located below the through-hole and can support the roll material about to enter the through-hole, allowing the roll material to enter the feeding box more smoothly. Two vertical rollers can be installed on the surface of the buffer steps to limit the roll material and reduce roll material deviation. A straightening component can also be added between the feeding box and the servo take-up roller to assist in the unfolding of the roll material.

[0017] The beneficial effects of this invention are as follows: 1. The fully automatic punch press feeder of this invention, through the setting of the punch and drive table, not only achieves stable coil feeding, but also delivers stable and orderly coils to the punch press. Furthermore, when friction feeding proves inadequate, a row of transmission holes can be pre-machined using a punching and drilling method. Then, direct drive is used to stably drive the coil forward. This not only improves the adaptability and practicality of the equipment, but also ensures that the drive wheel aligns with the hole in each transmission, forming a straight processing line. This guarantees that the coil remains on the straight line formed by the drive wheel and the punch during transport. Each transmission process provides subtle correction for the coil, ensuring precise feeding.

[0018] 2. The fully automatic punch press feeder of the present invention has a drive pin that can be pyramidal in shape, with its tail threaded to a connecting groove. The punching hole can be circular or keyway-shaped to ensure that the opening is fully adapted to the drive pin, allowing both positioning and transmission operations to proceed smoothly. During the adjustment phase, the drive wheel rises under the drive of the second lifting arm without contacting the coiled material. During the transmission phase, it is necessary to ensure that the drive wheel is in contact with the coiled material. A disassembly and assembly module can be integrated below the power table to replace the drive wheel with different drive pins, thereby adapting to different coiled materials and holes.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 8 As shown in the figure, an automatic punch press feeder according to an embodiment of the present invention includes a servo take-up roller 4 for winding raw materials, and a support frame 3 for support is installed at the end of the servo take-up roller 4; it also includes a feeding box 1, the front end of the feeding box 1 has a through opening 6 extending to the rear end, and the inner side of the feeding box 1 is sequentially provided with a feeding wheel set 8, a friction table 9, a punch 10, a drive table 11 and a discharge wheel set 7, the punch 10 includes an upper punch plate 23 and a lower punch plate 24 for punching the edge of the raw material, and the drive table 11 includes a drive wheel 28 adapted to the punching hole; During operation, the metal coil to be punched is fitted onto the outside of the servo take-up roller 4. The servo take-up roller 4 can be controlled by the system to release the coil at a uniform speed and in an orderly manner. One end of the coil enters the feeding box 1 through the through-hole 6, and then passes through the feed roller group 8, friction table 9, punch 10, drive table 11 and output roller group 7 before being sent out from the other end of the through-hole 6. The coil is horizontal after being sent out and is uniformly transported to the punch for punching. The feed roller group 8 and output roller group 7 provide power to the coil and drive it through friction. Forward; when the surface of the coil is smooth or has oil film or oil stains left from the rolling process, making it difficult for friction to move it smoothly, the punch 10 can be activated. The punch 10 can punch holes at the edge of the coil. The specific punching process is as follows: first, control the lower punch plate 24 to move to the bottom of the coil to provide support for the coil. Then, by lowering and merging the upper punch plate 23, the punching work is completed using the punching parts at the bottom of the upper punch plate 23. The punching position needs to be at the strip part of the coil edge, which does not participate in the subsequent punching. The process begins with the coil material moving forward. The drive wheel 28 has protrusions on its surface that match the holes; these protrusions can be conical or toothed. As the drive wheel 28 rotates, the protrusions engage with the holes, steadily transporting the coil material forward. Subsequently, the punch 10 continuously punches out equidistant holes, thus completing the fully automatic coil material transport function. This setup not only achieves stable coil material feeding, providing a stable and orderly feed to the punch press, but also allows for efficient handling of friction feeding situations. By using a stamping and punching method, a row of transmission holes is pre-machined, and then a direct drive method is used to stably drive the coil material to move forward and feed. This not only improves the adaptability and practicality of the equipment, but also ensures that the drive wheel 28 is aligned with the hole each time it is driven, forming a straight processing line. This ensures that the coil material always stays on the straight line formed by the drive wheel 28 and the stamping part during transportation. Each transmission process can perform a fine correction for the coil material, ensuring the accurate feeding process of the coil material. The friction table 9 is located after the feed roller group 8, which can grind and clean the surface of the coiled material, removing some oil and burrs. This not only provides pretreatment for the stamping process of the punch press, but also removes oil and dust by cleaning and eliminates rust and minor defects by grinding, which can significantly reduce the probability of scratches, pits, orange peel and other defects on the surface of the stamped parts. When the feed roller group 8 and the discharge roller group 7 are still insufficient for the transportation work after grinding and cleaning, the punch press 10 and the drive table 11 are used for punching and transportation, saving energy. At the same time, grinding and cleaning can also help the stamping work of the punch press 10.

[0023] The feed roller group 8 and the discharge roller group 7 are located near the through opening 6. The discharge roller group 7 includes multiple rotating and lifting conveyor rollers, which are divided into upper and lower groups. The feed roller group 8 includes two power wheels 12, and each end of the power wheel 12 is equipped with a lifting platform 13 for driving the power wheel 12 to rise and fall. During operation, multiple lifting and rotating transport rollers are used to clamp the coil at the exit end, providing some of the power to transport the coil outward. When the friction is sufficient, it is enough to transport the coil. When the friction is insufficient, it can also provide some guiding force to ensure that the coil is stably discharged from the through-hole 6 at the exit. The feed roller group 8 has the same function as the discharge roller group 7. The inner wall of the feed box 1 is equipped with a drive component for driving the transport rollers and the lifting platform 13 to lift. It can be a screw and nut mechanism.

[0024] The press 10 includes an upper hydraulic platform 19 and a lower support platform 21 that are fixedly connected to each other. The bottom drive end of the upper hydraulic platform 19 is fixedly connected to the upper press plate 23. The top of the lower support platform 21 is equipped with a lifting arm 25 that can be raised and lowered. The top of the lifting arm 25 is fixedly connected to the lower press plate 24. During operation, the lower support platform 21 is aligned with the bottom of the coil material under the adjustment of the lifting arm 25, ensuring that the coil material moves horizontally in the feeding box 1. Then, under the pressing of the lower stamping plate 24, it works with the stamping parts at the bottom of the lower stamping plate 24 to complete the equidistant opening of multiple holes.

[0025] The drive platform 11 includes a power platform 26. A synchronous slide rail 20 is installed on the side of the upper hydraulic platform 19 near the power platform 26. The moving end of the synchronous slide rail 20 is fixedly connected to the power platform 26. An electric slide rail 18 for driving the lower support platform 21 to move horizontally is installed at the bottom of the lower support platform 21. During operation, the lower support platform 21 is moved horizontally by the electric slide rail 18, thereby moving the upper stamping plate 23 and the lower stamping plate 24 to the edge position where the coil needs to be opened, thus adapting to the opening work of different requirements. The power platform 26 moves synchronously with the upper hydraulic platform 19 and is finely adjusted by the synchronous slide rail 20 to ensure that the position of the drive wheel 28 and the opening position are on a straight line.

[0026] The power platform 26 has a sliding locking mechanism for a lifting arm 27 that can be raised and lowered. A drive motor is fixedly connected to the bottom of the lifting arm 27. The output end of the drive motor is fixedly connected to the drive wheel 28. The surface of the drive wheel 28 is provided with a plurality of drive posts 32. The surface of the drive wheel 28 is provided with a plurality of connecting grooves for fixing the drive posts 32. The plurality of connecting grooves are arranged in a ring at equal intervals. During operation, the drive pile 32 can be pyramidal in shape, with its tail threaded to the connecting groove. The punching hole can be circular or keyway-shaped to ensure that the opening is fully adapted to the drive pile 32, allowing both positioning and transmission operations to proceed smoothly. During the adjustment phase, the drive wheel 28 rises under the drive of the lifting arm 27 without contacting the coiled material. During the transmission phase, it is necessary to ensure that the drive wheel 28 is in contact with the coiled material. A disassembly and assembly module can be integrated below the power platform 26 to replace the drive wheel 28 with different drive piles 32, thereby adapting to different coiled materials and holes.

[0027] The bottom of the second lifting arm 27 is slidably connected to an extension arm 30 capable of lifting. The bottom of the extension arm 30 is fixedly connected to a material plate 29. The surface of the material plate 29 is provided with a cutting groove 31 that is flush with the position of the drive wheel 28. During operation, in order to ensure smooth transmission, a material plate 29 is set at the bottom of the drive wheel 28 to support the coiled material. The height can be freely adjusted under the drive of the extension arm 30. The setting of the cutting groove 31 allows the drive pile 32 passing through the hole to move.

[0028] The surface of the lower stamping plate 24 is provided with a detachable replacement plate 35. The surface of the replacement plate 35 is provided with a stamping groove 33 that is compatible with the upper stamping plate 23. The surface of the lower stamping plate 24 is provided with a positioning groove 34 that is compatible with the upper stamping plate 23. During operation, different replacement plates 35 can be used to adapt to different stamping parts, thereby stamping out holes of the required shape. The bottom of the upper stamping plate 23 is also provided with a column, which is inserted into the positioning groove 34 during stamping to ensure the accuracy of stamping.

[0029] A hollow groove is provided in the middle of the lifting arm 25. The top of the hollow groove is connected to the bottom of the drive pile 32. An outwardly inclined material guiding slide frame 22 is installed on the outer side of the lower support platform 21. The material guiding slide frame 22 is connected to the hollow groove of the lifting arm 25. During operation, the waste generated by stamping slides downward through the middle of the drive pile 32 and is eventually discharged from the inclined feed slide frame 22, ensuring the smooth operation of continuous stamping.

[0030] The friction platform 9 includes two lifting platforms 14 that can be raised and lowered. A linkage wheel set 16 is installed between the two lifting platforms 14, and a friction belt 15 is installed on the outer side of the linkage wheel set 16. During operation, the drive unit in the feeding box 1 is also used to control the lifting and lowering of the lifting platform 14 and the opening and closing of the two sets of friction belts 15, so that it can fit rolls of different thicknesses. With the drive of the linkage wheel group 16, the friction belts 15 are driven to rotate, thereby rubbing and cleaning the surface of the roll. A spraying device can also be integrated on the outside of the friction platform 9 to provide cleaning water for cleaning and to improve the cleaning effect.

[0031] The bottom of the feeding box 1 is fixedly connected to a power supply base 2, and both sides of the feeding box 1 are fixedly connected to arc-shaped buffer steps 5, which are located below the through opening 6. During operation, the buffer step 5 can lift the roll material that is about to enter the through-hole 6, allowing the roll material to enter the feed box 1 more smoothly. Two vertical rollers can be installed on the surface of the buffer step 5 to limit the roll material and reduce roll material deviation. A straightening component can also be added between the feed box 1 and the servo take-up roller 4 to assist in the unfolding of the roll material.

[0032] During operation, the metal coil to be punched is fitted onto the outside of the servo take-up roller 4. The servo take-up roller 4 can be controlled by the system to release the coil at a uniform speed and in an orderly manner. One end of the coil enters the feeding box 1 through the through-hole 6, and then passes through the feed roller group 8, friction table 9, punch 10, drive table 11 and output roller group 7 before being sent out from the other end of the through-hole 6. The coil is horizontal after being sent out and is uniformly transported to the punch for punching. The feed roller group 8 and output roller group 7 provide power to the coil and drive it through friction. Forward; when the surface of the coil is smooth or has oil film or oil stains left from the rolling process, making it difficult for friction to move it smoothly, the punch 10 can be activated. The punch 10 can punch holes at the edge of the coil. The specific punching process is as follows: first, control the lower punch plate 24 to move to the bottom of the coil to provide support for the coil. Then, by lowering and merging the upper punch plate 23, the punching work is completed using the punching parts at the bottom of the upper punch plate 23. The punching position needs to be at the strip part of the coil edge, which does not participate in the subsequent punching. The process begins with the coil material moving forward. The drive wheel 28 has protrusions on its surface that match the holes; these protrusions can be conical or toothed. As the drive wheel 28 rotates, the protrusions engage with the holes, steadily transporting the coil material forward. Subsequently, the punch 10 continuously punches out equidistant holes, thus completing the fully automatic coil material transport function. This setup not only achieves stable coil material feeding, providing a stable and orderly feed to the punch press, but also allows for efficient handling of friction feeding situations. By using a stamping and punching method, a row of transmission holes is pre-machined, and then a direct drive method is used to stably drive the coil material to move forward and feed. This not only improves the adaptability and practicality of the equipment, but also ensures that the drive wheel 28 is aligned with the hole each time it is driven, forming a straight processing line. This ensures that the coil material always stays on the straight line formed by the drive wheel 28 and the stamping part during transportation. Each transmission process can perform a fine correction for the coil material, ensuring the accurate feeding process of the coil material. The friction table 9 is located after the feed roller group 8, which can grind and clean the surface of the coiled material, removing some oil and burrs. This not only provides pretreatment for the stamping process of the punch press, but also removes oil and dust by cleaning and eliminates rust and minor defects by grinding, which can significantly reduce the probability of scratches, pits, orange peel and other defects on the surface of the stamped parts.

At the same time, grinding and cleaning can also help the stamping work of the punch press 10.

[0033] Multiple lifting and rotating transport rollers are used to clamp the coil at the exit end, providing some of the outward transport power to the coil. When the friction is sufficient, it is enough to transport the coil. When the friction is insufficient, it can also provide some guiding force to ensure that the coil is stably discharged from the through-hole 6 at the exit. The feed roller group 8 has the same function as the discharge roller group 7. The inner wall of the feed box 1 is equipped with a drive component for driving the transport rollers and the lifting platform 13 to lift. It can be a screw and nut mechanism.

[0034] The lower support platform 21 is aligned with the bottom of the coil material under the adjustment of the lifting arm 25, ensuring that the coil material moves horizontally in the feeding box 1. Then, under the pressing of the lower stamping plate 24, it works with the stamping parts at the bottom of the lower stamping plate 24 to complete the equidistant opening of multiple holes.

[0035] The lower support platform 21 is moved horizontally by the electric slide rail 18, thereby moving the upper stamping plate 23 and the lower stamping plate 24 to the edge position where the coil needs to be opened, so as to adapt to the opening work of different requirements. The power platform 26 moves synchronously with the upper hydraulic platform 19 and is finely adjusted by the synchronous slide rail 20 to ensure that the position of the drive wheel 28 and the opening position are on a straight line.

[0036] The drive pile 32 can be pyramidal in shape, with its tail threaded to the connecting groove. The punching hole can be circular or keyway-shaped to ensure that the opening is fully adapted to the drive pile 32, allowing the positioning and transmission operations to proceed smoothly. During the adjustment phase, the drive wheel 28 rises under the drive of the lifting arm 27 without contacting the coil. During the transmission phase, it is necessary to ensure that the drive wheel 28 is in contact with the coil. A disassembly and assembly module can be integrated below the power platform 26 to replace the drive wheel 28 with different drive piles 32, thereby adapting to different coils and holes.

[0037] To ensure smooth transmission, a material plate 29 is installed at the bottom of the drive wheel 28 to support the coiled material. The height can be freely adjusted under the drive of the extension arm 30. The cutting groove 31 allows the drive pile 32, which passes through the hole, to move.

[0038] By using different replacement plates 35, different stamping parts can be adapted, thus punching out holes of the required shape. The bottom of the upper stamping plate 23 is also provided with a column, which is inserted into the positioning groove 34 during stamping to ensure the accuracy of stamping.

[0039] The waste generated during stamping slides downward through the middle of the drive pile 32 and is eventually discharged from the inclined feed slide frame 22, ensuring the smooth operation of continuous stamping.

[0040] The drive unit in the feeding box 1 is also used to control the lifting and lowering of the lifting platform 14 and the opening and closing of the two sets of friction belts 15, so that it can fit rolls of different thicknesses. With the drive of the linkage wheel set 16, the friction belts 15 are driven to rotate, thereby rubbing and cleaning the surface of the roll. A spraying device can also be integrated on the outside of the friction platform 9 to provide cleaning water for cleaning and to improve the cleaning effect.

[0041] The buffer step 5 can lift the roll material that is about to enter the through-hole 6, allowing the roll material to enter the feed box 1 more smoothly. Two vertical rollers can be installed on the surface of the buffer step 5 to limit the roll material and reduce roll material deviation. A straightening component can also be added between the feed box 1 and the servo take-up roller 4 to assist the unwinding of the roll material.
