Description

Technical Field

[0001] This invention relates to the field of metal stamping technology, and in particular to a metal stamping blanking device for manufacturing metal medals. Background Technology

[0002] Metal medals, as core craft products for sports awards, honors, and business gifts, are widely used in many fields such as sports events, school awards, corporate awards, and cultural tourism souvenirs. The mainstream base materials include a variety of metal sheets such as brass, copper, aluminum alloy, zinc alloy, and stainless steel. With their advantages of excellent metallic texture, strong wear resistance, and long preservation period, they have become core products in the commemorative gift industry. Stamping is the first core process in the production of metal medals. It directly determines the dimensional accuracy, shape regularity, and surface flatness of the medal blank. It is the foundation for ensuring the quality of subsequent deep processing processes such as polishing, electroplating, baking paint, relief stamping, and film coating. It plays a decisive role in the appearance and quality of the finished medal and the yield rate.

[0003] Chinese patent CN121820427A discloses a stamping forming equipment for metal product processing. The equipment uses the bottom roller and top roller in the feeding assembly to clamp the sheet metal and utilizes friction to achieve automatic feeding of the sheet metal. This eliminates the need for manual placement, reduces labor intensity, and improves feeding efficiency.

[0004] While the above-mentioned automatic conveying and stamping of metal sheets can achieve the cutting and separation of medal blanks, it cannot complete the pre-stamping of the medal surface relief at the same time as cutting and blanking. It needs to be completed in two separate processes, resulting in low processing efficiency. Secondly, the lack of stable adsorption and fixation of the sheet before stamping makes it easy for the sheet to shift during stamping and cutting, resulting in insufficient dimensional accuracy of the blank. At the same time, the metal debris generated during the stamping process cannot be collected in time, which can easily adhere to the surface of the sheet and affect the accuracy of the stamping relief, as well as pollute the processing environment. Furthermore, the finished products after stamping often need to be removed manually, which not only reduces work efficiency but also increases safety hazards. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides the following technical solution: A metal stamping and blanking device for manufacturing metal medals, comprising a worktable, a stamping table fixedly connected to the top of the worktable via a bracket, a stamping port being provided on the top of the stamping table, a blanking mechanism fixedly connected to the portion of the top of the worktable below the stamping table, stamping devices fixedly connected to both sides of the worktable, a support frame fixedly connected to the top of the worktable, guide rollers rotatably connected to the inner wall of the support frame, a drive roller driven by a motor rotatably connected to the portion of the inner wall of the support frame on one side of the guide rollers, an adjustment assembly fixedly connected to the top of the support frame, and an inclined blanking channel provided on the top of the worktable. The inclined feeding channel is used to receive the stamped metal medal blanks sent by the feeding mechanism. A collection box is provided on the top of the worktable. The collection box is connected to the bottom end of the inclined feeding channel and is used to catch the finished blanks sliding out of the inclined feeding channel. A guide slide is provided at the bottom of the stamping table. The guide slide is connected to the stamping port and guides the up and down sliding of the feeding mechanism. The stamping device includes a support frame installed on the top of the worktable on both sides of the stamping table. The fixed end of the stamping cylinder is fixedly connected to the top of the support frame. A connecting plate is connected to the movable end of the stamping cylinder. Compression springs are evenly fixedly connected to the bottom of the connecting plate. A stamping head is fixedly connected to the bottom of the compression springs.

[0006] Preferably, the stamping device further includes guide rods, two sets of which are fixedly connected to the top of the stamping head. The top of the guide rods passes through the bottom of the connecting plate and is slidably connected to the connecting plate. Two sets of threaded adjusting rods are symmetrically arranged on the top of the stamping head, both rotatably connected to the top of the stamping head. The top of the threaded adjusting rods passes through the bottom of the connecting plate and is slidably connected to the connecting plate. An adjusting nut is threadedly connected to the portion of the threaded adjusting rod above the connecting plate. A cutter with a ring structure is located at the bottom of the connecting plate and surrounds the stamping head. Cleaning brushes are evenly fixedly connected to the side of the cutter. The stamping cylinder drives the stamping head and the cutter to move downwards synchronously. First, the stamping head with a compression spring buffers the compression to complete the medal relief forming, preventing the blank from cracking. Then, the cutter, in conjunction with the ring groove, cuts the blank, reducing processing burrs. The stamping depth can be changed by adjusting the threaded adjusting rods to adapt to different processing specifications, realizing integrated forming and cutting operations, improving processing efficiency and finished product flatness.

[0007] Preferably, the stamping table has an internal cavity, the top of the stamping table has uniformly spaced adsorption positioning holes, the inner wall of the stamping port has uniformly spaced dust suction holes, the adsorption positioning holes and the dust suction holes are connected to the internal cavity of the stamping table, and a vacuum suction pipe is connected through and fixedly connected to one side of the stamping table, the vacuum suction pipe is connected to the internal cavity of the stamping table.

[0008] Preferably, an inclined dust filter plate is fixedly connected to one side of the vacuum suction pipe on the inner wall of the cavity, and a collection channel is connected to the bottom of the cavity. A recycling drawer is slidably connected through one side of the collection channel. An L-shaped fixing plate is fixedly connected to the bottom of the stamping table, and a flexible top rod is fixedly connected to the bottom of the inner wall of the L-shaped fixing plate. The cavity of the stamping table forms a negative pressure through the vacuum suction pipe, which firmly adsorbs and fixes the metal sheet through the adsorption positioning hole, preventing stamping displacement and ensuring processing accuracy. During the stamping operation, metal debris swept by the brush enters the cavity through the dust suction hole, is filtered by the inclined dust filter plate and collected into the recycling drawer, automatically cleaning dust and impurities, optimizing the processing environment and reducing manual maintenance costs.

[0009] Preferably, the adjustment assembly includes an adjustment frame, two sets of which are symmetrically fixedly connected to the top of the support frame. The adjustment frame has a frame structure with openings on both sides. A connecting block is slidably connected to the inner wall of the adjustment frame. An adjusting screw is rotatably connected to the top of the connecting block. The top of the adjusting screw passes through the top of the inner wall of the adjustment frame and is threadedly connected to the adjustment frame. A knob is fixedly connected to the top of the adjusting screw.

[0010] Preferably, a long plate is fixedly connected to the side of the connecting block, and a hollow brush roller and a bonding roller are rotatably connected between the two sets of long plates. The hollow brush roller has uniformly spaced dust suction ports on its side. A drive motor is fixedly connected to the side of the long plate, and the drive shaft of the drive motor passes through the long plate and is fixedly connected to the hollow brush roller. A dust suction pipe passes through and is rotatably connected to the side of the long plate. The dust suction pipe is externally connected to a dust removal fan and is internally connected to the hollow brush roller. The distance between the roller sets can be adjusted by a knob and screw structure to accommodate metal sheets of different thicknesses, achieving bonding, clamping, and conveying, preventing slippage during feeding. During feeding, the hollow brush roller rotates to clean impurities on the surface of the sheet, and the dust removal fan uses negative pressure to remove debris and stains, completing the pre-cleaning operation of the sheet, preventing impurities from affecting the stamping and forming effect, and improving the precision of the finished medal.

[0011] Preferably, the feeding mechanism includes a fixed base plate, with shock-absorbing springs uniformly fixedly connected to the top of the fixed base plate. The fixed end of an elastic telescopic rod is fixedly connected to the portion of the top of the fixed base plate located inside the shock-absorbing springs. The movable end of the elastic telescopic rod is rotatably connected to a lifting circular plate via a bracket. Buffer springs are uniformly fixedly connected to the top of the lifting circular plate. A receiving circular plate is fixedly connected to the top of the buffer springs. An annular groove is provided on the top of the receiving circular plate.

[0012] Preferably, a rotating platform is fixedly connected to the center of the bottom of the lifting circular plate, and rotating frames are rotatably connected to both sides of the rotating platform. The movable end of the feeding cylinder is fixedly connected to the bottom of the rotating frame, and the fixed end of the feeding cylinder is fixedly connected to the top of the fixed base plate. The fixed base plate is fixedly connected to the top of the worktable. The sides of the lifting circular plate and the receiving circular plate are slidably connected to the inner wall of the guide slide. During the stamping process, multiple sets of springs and elastic telescopic rods buffer the impact of the stamping, reducing equipment vibration and noise, and protecting equipment parts. After the stamping is completed, the feeding cylinder drives the receiving circular plate to move down, and the flexible top rod makes it tilt automatically. The medal blanks fall and are collected by gravity, realizing fully automatic feeding, reducing manual labor intensity, and improving the efficiency of automated processing.

[0013] The beneficial effects of the technical solution provided by this invention include: 1. This metal stamping and blanking equipment for manufacturing metal medals is equipped with a stamping device, realizing integrated operation of metal medal relief stamping and cutting blanking. It has high processing efficiency and excellent finished product quality. Relying on the extrusion spring to buffer the impact force of stamping, it effectively prevents the metal blank from cracking under pressure. At the same time, the cutter and the stamping head work together to cut precisely, effectively reducing burrs on the cut surface and ensuring that the blank edge is flat. The depth of the stamping head can be flexibly adjusted by the threaded adjustment rod to precisely control the depth of medal relief forming. It is suitable for a variety of relief processing specifications, effectively simplifying the processing process and improving the accuracy and processing efficiency of medal stamping.

[0014] 2. This metal stamping blanking equipment for manufacturing metal medals relies on a negative pressure adsorption and automatic dust collection and recovery structure to ensure stamping accuracy and operational cleanliness. Before stamping, the metal sheet is firmly fixed through the negative pressure adsorption holes of the stamping table to prevent the sheet from shifting and shaking during the stamping process, thus improving the stability of blanking and stamping. Metal chips and dust generated during processing can be swept away and sucked into the cavity during stamping. After being filtered by the inclined dust filter plate and vacuum suction, they slide down the inclined sliding surface to the recovery drawer, realizing automatic cleaning and recovery of dust and chips, improving the working environment, reducing the frequency of manual maintenance, and improving the overall stamping efficiency.

[0015] 3. This metal stamping blanking equipment for manufacturing metal medals is equipped with an adjustment component. The roller spacing can be flexibly adjusted by adjusting the lead screw to adapt to the conveying of metal sheets of different thicknesses. The equipment clamps the sheet throughout the process, avoiding slippage and deviation during feeding, and ensuring stable feeding accuracy. During the feeding process, the hollow brush rollers clean the surface of the sheet at high speed to remove stains and attached debris. The dust removal fan removes impurities in real time, ensuring the cleanliness of the stamping raw material sheet and preventing impurities from being pressed into the sheet, causing relief defects and indentation defects. This further improves the stamping quality and finished product precision of the medals.

[0016] 4. This metal stamping blanking equipment for manufacturing metal medals is equipped with a blanking mechanism. After stamping, the medal blank can be automatically tilted and slid out, eliminating the need for manual material handling, significantly reducing labor intensity, and improving the automation level of the equipment. The equipment is equipped with multiple springs and elastic buffer structures to absorb the impact of stamping, effectively reducing equipment vibration, preventing loosening and wear of parts, extending the service life of the equipment, reducing stamping noise, ensuring long-term stable operation of the equipment, and further improving the processing efficiency and durability of batch stamping blanking of medals.

[0019] For the first embodiment, please refer to... Figures 1-4 This invention provides a metal stamping and blanking device for manufacturing metal medals. By setting up a stamping device 3, after the coiled material is positioned on the stamping table 2, the stamping cylinder 32 is activated. The movable end of the stamping cylinder 32 pushes the connecting plate 33 downwards. The downward movement of the connecting plate 33 causes the stamping head 37 below the cutter 35 extending from the annular structure to move downwards. Simultaneously, the cutter 35 moves downwards in sync. During stamping, the stamping head 37 first extrudes and shapes the metal sheet. During the stamping process, the compression spring 38 buffers the impact force of the stamping to prevent excessive impact force from causing the medal blank to crack. During stamping, the stamping head 37 is compressed and moves upwards. At the same time, the guide rod 39 and the threaded adjusting rod 310 move upwards simultaneously, compressing the compression spring 38. When the stamping head 37 moves to be flush with the bottom end of the cutter 35... When the cutting blade 35 moves along the edge of the stamping head 37 towards the annular groove 47, the annular groove 47 can work with the cutting blade 35 to completely cut the metal sheet, reduce burrs, and ensure the flatness of the processing. When it is necessary to adjust the depth of the relief forming, rotate the threaded adjusting rod 310 to change the relative position between the top of the threaded adjusting rod 310 and the connecting plate 33, and then tighten the adjusting nut 34 to fix the position, thereby adjusting the initial distance between the stamping head 37 and the bottom of the cutting blade 35, and thus controlling the relief extrusion depth of the stamping head 37 to adapt to different processing requirements. Through the above operations, stable relief stamping and blanking cutting integrated processing is achieved without the need for multiple process switching. It can also flexibly adjust the relief stamping depth according to the requirements to adapt to different processing requirements, thereby improving the overall stamping processing efficiency.

[0020] Second embodiment, please refer to Figures 1-6By setting up a stamping table 2 with an internal cavity, and connecting a vacuum suction pipe 16 to an external vacuum device, the vacuum suction pipe 16 will create a negative pressure inside the cavity of the stamping table 2 before stamping. The negative pressure inside the cavity will act on the metal sheet above the stamping table 2 through the adsorption positioning hole 14, stably adsorbing the metal sheet onto the surface of the stamping table 2, preventing the sheet from shifting during the stamping process, and ensuring the accuracy of the stamping and cutting. At the same time, during the stamping and cutting process, the cleaning brush 36 on the side of the cutter 35 sweeps off the metal debris and dust generated during stamping that are attached to the inner wall of the stamping port 12. The debris and dust enter the cavity inside the stamping table 2 through the dust suction hole 13, and the inclined dust filter plate 17 blocks the debris and dust in the airflow, causing them to fall into the air. The surface of the tilted dust filter plate 17 slides into the collection channel 18 after the vacuuming is completed, and finally enters the recycling drawer 19. The operator can directly pull it out for cleaning, avoiding the spread of dust and debris that pollutes the processing environment. It also eliminates the need for frequent manual cleaning of the stamping table 2, reducing the cost of manual maintenance. When stamping is completed, the vacuum suction stops, and the adsorption force of the sheet disappears, making it easy to move the scrap sheet after stamping and facilitate the next feeding process. Through the above operations, stable adsorption and positioning of the sheet during stamping is achieved, avoiding the sheet displacement from affecting the cutting accuracy. At the same time, it can automatically collect the dust and debris generated during processing, making it easy to clean up. This reduces the maintenance burden on the operator and further improves the efficiency and quality of stamping.

[0021] Third embodiment, please refer to Figures 1-7 By incorporating the adjustment component 8, during the feeding of the metal sheet, the motor drives the drive roller 7 to rotate, causing the metal sheet to move between the guide roller 6, the bonding roller 87, and the hollow brush roller 86. Depending on the thickness of the metal sheet being processed, rotating the knob 84 drives the adjusting screw 83 to rotate. The adjusting screw 83 causes the connecting block 82 to slide downwards along the inner wall of the adjustment frame 81. The connecting block 82 then causes the long plate 85 to move downwards, thereby adjusting the distance between the bonding roller 87, the hollow brush roller 86, and the drive roller 7. This adapts to different sheet thicknesses, ensuring that the sheet is always bonded during feeding. The material is clamped tightly to prevent slippage during feeding and ensure feeding accuracy. During the feeding process, at the initial clamping position of the board, the hollow brush roller 86 cleans the brushes on the board surface in sync with the downward movement of the long plate 85. The drive motor 89 drives the hollow brush roller 86 to rotate, brushing off the debris and stains attached to the board surface. At the same time, the dust removal fan sucks away the brushed debris and dust through the dust suction pipe 810 and the dust suction port 88 on the side wall of the hollow brush roller 86, keeping the board surface clean and preventing impurities from affecting the forming quality of the stamping relief, further improving the processing accuracy of the finished product.

[0022] For the fourth embodiment, please refer to [link / reference]. Figures 1-8By setting up the unloading mechanism 4, when the metal sheet is stamped, the cutter 35 moves down and drives the bottom of the cutter 35 into the annular groove 47, cutting the formed medal blank from the sheet. The cut blank falls onto the receiving circular plate 46. During the stamping process, the shock-absorbing spring 42 and the elastic telescopic rod 43 initially buffer the impact force generated by the stamping. The buffer spring 45 further buffers and absorbs the impact force of the stamping, reducing the vibration generated by the stamping, avoiding the vibration from causing the internal parts of the equipment to loosen, extending the service life of the equipment, and reducing the noise caused by the vibration. After the stamping is completed, the cutter 35 is lifted and the unloading operation begins. During the unloading, the movable end of the unloading cylinder 410 at the bottom of the rotating frame 49 retracts and pulls the rotating frame 49 down. The downward movement of the rotating frame 49 drives the rotating table 48 down, and the downward movement of the rotating table 48 drives the lifting circular plate 44 along the guide slide 1. The inner wall guides the downward sliding mechanism. The lifting disc 44 moves downward, causing the buffer spring 45 and the receiving disc 46 to move downward synchronously. When the receiving disc 46 moves down to a position lower than the feed end of the inclined feeding channel 9, the bottom of the lifting disc 44 is lifted upward by the flexible push rod 15 and tilts. After the lifting disc 44 tilts, it causes the receiving disc 46 to tilt. The formed medal blank slides down the inclined surface of the receiving disc 46 under the action of gravity to the inclined feeding channel 9, and finally slides down from the inclined feeding channel 9 to the collection box 10 for collection. This realizes automatic stamping and feeding, eliminating the need for manual removal of the processed medal blank, reducing the workload of operators. At the same time, the multiple buffer structure can effectively offset the impact force generated by stamping, reduce equipment vibration, extend equipment service life, reduce processing noise, improve the automation level of feeding, and improve the overall stamping efficiency.

[0023] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
