Description

Technical Field

[0001] This invention belongs to the field of stamping equipment technology, specifically relating to a stamping die for harmonica production reeds. Background Technology

[0002] The harmonica is a wind instrument that produces sound through the vibration of a reed. Its core component is the reed, which is usually made of stamped copper or stainless steel strip. The thickness and length of the reeds vary depending on the pitch.

[0003] Therefore, in traditional harmonica production, metal strips of different thicknesses need to be pre-made according to different notes. Then, during reed processing, reeds for one note are stamped in the same batch. These reeds are then collected together, and a new mold is used to stamp reeds for another note, or multiple stamping machines are used to produce reeds for different notes. Workers then fix the reeds of different notes onto the reed plate, adjust them, and then assemble other accessories to complete the harmonica. This method has low production efficiency. Operators need to correctly fix the reeds of different notes in different positions on the reed plate; if even one reed is placed incorrectly, the harmonica will fail and become a defective product. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a reed stamping die for harmonica production. The present invention can produce reeds of multiple scales in one stamping, and the reeds can be arranged neatly in the scale order after they are produced, effectively preventing the sequence error during subsequent reed fixing and installation, effectively improving production efficiency, reducing the probability of error, and improving the yield rate.

[0005] The technical solution adopted to solve the above technical problems is: a reed stamping die for harmonica production, including a stamping mechanism, a die assembly and a feeding mechanism. The feeding mechanism is fixedly installed on the ground, the stamping mechanism is fixedly installed on one side of the feeding mechanism, the die assembly is installed above the feeding mechanism, and a material-bearing component is fixedly installed on the top of the feeding mechanism. The stamping mechanism can drive the die assembly to stamp the material to be processed. A driving assembly is rotatably connected to one side of the feeding mechanism, and the stamping mechanism can drive the feeding mechanism through the driving assembly.

[0006] The material to be processed after being stamped by the mold assembly can fall onto the material-bearing component on the feeding mechanism.

[0007] Through the above technical solution, the mold assembly is equipped with clearance grooves that allow metal strips of different pitches to pass through. Pre-made metal strips of different pitches are conveyed to the mold assembly by a feeding device. The stamping mechanism drives the mold assembly to stamp the metal strips of different pitches. The reeds of different pitches formed after stamping fall onto the receiving component. The receiving component is equipped with receiving grooves for different pitch reeds corresponding to the mold assembly, so that the reeds of different pitches falling onto the receiving component are arranged in sequence. Operators will not install them incorrectly in the subsequent reed installation and fixing process, which effectively improves efficiency, reduces installation errors, and improves the yield rate. While the stamping mechanism drives the mold assembly to stamp, it drives the conveying mechanism to move through the drive assembly, which in turn drives the receiving component to move. This ensures that with each stamping, a receiving component without reeds moves to the bottom of the mold assembly, that is, each receiving component only carries one set of reeds, which facilitates the subsequent operation of the operator.

[0008] Furthermore, the mold assembly includes a fixed mold, a pad, a moving mold, a buffer spring, and a processing frame. The processing frame is fixedly set on the ground, the fixed mold is fixedly connected to the processing frame, the pad is slidably connected above the fixed mold, the moving mold is slidably connected above the pad, and a stamping head is slidably connected to the stamping mechanism. The bottom of the stamping head is fixedly connected to the top of the moving mold.

[0009] With the above technical solution, since the processing frame is fixedly set on the ground, the fixed mold is fixedly connected to the processing frame, the pad is slidably connected above the fixed mold, the moving mold is slidably connected above the pad, and the stamping mechanism is slidably connected to the stamping head, the bottom of the stamping head is fixedly connected to the top of the moving mold, so that the raising and lowering of the stamping mechanism can drive the moving mold to rise and fall, thereby stamping the metal strip to be processed.

[0010] Furthermore, a guide post is fixedly connected to the top of the fixed mold, the guide post passes through the pad and the moving mold, the pad is slidably connected to the guide post, the moving mold is slidably connected to the guide post, a limit block is fixedly connected to the top of the guide post, a guide rod is fixedly connected to the top of the pad, the guide rod passes through the moving mold, the moving mold is slidably connected to the guide rod, a buffer spring is sleeved on the guide rod, the bottom of the buffer spring is fixedly connected to the top of the pad, the top of the buffer spring is fixedly connected to the bottom of the moving mold, and a limit plate is fixedly connected to the top of the guide rod.

[0011] With the above technical solution, a guide post is fixedly connected to the top of the fixed mold. The guide post passes through the pad and the moving mold. The pad is slidably connected to the guide post. The moving mold is slidably connected to the guide post. A limit block is fixedly connected to the top of the guide post. A guide rod is fixedly connected to the top of the pad. The guide rod passes through the moving mold. The moving mold is slidably connected to the guide rod. A buffer spring is sleeved on the guide rod. The bottom of the buffer spring is fixedly connected to the top of the pad. The top of the buffer spring is fixedly connected to the bottom of the moving mold. A limit plate is fixedly connected to the top of the guide rod. When the moving mold descends, it can drive the pad to descend. The descending pad can press down the metal strip to be processed. Then the moving mold continues to descend to stamp the metal strip to be processed.

[0012] Furthermore, a cutting tool is fixedly connected to the bottom of the moving mold, and the cutting tool can penetrate the pad and the fixed mold.

[0013] Through the above technical solution, since the bottom of the moving mold is fixedly connected with a cutting tool, the cutting tool can penetrate the pad and the fixed mold, so that the moving mold can lift and lower the cutting tool, and the cutting tool can cooperate with the fixed mold to press the metal strip to be processed into a spring. There are multiple cutting tools and multiple grooves on the fixed mold, so that multiple springs of different pitches can be formed in one stamping.

[0014] The cutting tool can penetrate the pad and the fixed mold, allowing it to press the stamped spring sheet out of the bottom of the fixed mold, thus realizing the discharge of the spring sheet.

[0015] Furthermore, the material conveying mechanism includes a feeding belt, a frame, and driven rollers. The frame is fixedly connected to the ground, and multiple driven rollers are rotatably connected to the frame. The feeding belt is sleeved on the multiple driven rollers.

[0016] With the above technical solution, since the frame is fixedly connected to the ground, multiple driven rollers are rotatably connected to the frame, and the feeding belt is sleeved on multiple driven rollers, the rotation of the driven rollers can drive the feeding belt.

[0017] Furthermore, a positioning plate is fixedly connected to the feeding belt, and multiple positioning plates are equidistantly arranged on the feeding belt. Multiple second ventilation slots are equidistantly arranged on the feeding belt. Multiple positioning slots are provided at the bottom of the material-bearing component, and multiple first ventilation slots are provided at the bottom of the material-bearing component. The positioning plate can be locked in the positioning slot, and the second ventilation slots can overlap with the first ventilation slots.

[0018] With the above technical solution, since a positioning plate is fixedly connected to the feeding belt, and multiple positioning plates are equidistantly arranged on the feeding belt, and multiple second ventilation slots are equidistantly arranged on the feeding belt, multiple positioning slots are provided at the bottom of the material-bearing component, and multiple first ventilation slots are provided at the bottom of the material-bearing component, the positioning plate can be locked in the positioning slot, and the second ventilation slots can overlap with the first ventilation slots, so that multiple material-bearing components can be fixed on the feeding belt, and the feeding belt can drive the material-bearing components to move horizontally;

[0019] Magnets can be installed inside the positioning plate, and iron sheets can be placed inside the positioning groove. The iron sheets are attracted to the magnets, making it easy for the material-bearing components to be accurately installed on the feeding belt.

[0020] Furthermore, the drive assembly is rotatably connected to the frame. The drive assembly includes a drive disk and an eccentric disk. The drive disk is located inside the frame, and the eccentric disk is located outside the frame. The drive disk shaft is fixedly connected to the eccentric disk shaft. Transmission teeth are provided on both sides of the feed belt. Incomplete teeth are provided on the edge of the drive disk. The incomplete teeth mesh with the transmission teeth. Driven gears are fixedly connected to both sides of the driven roller. The driven gears mesh with the transmission teeth.

[0021] With the above technical solution, since the drive disc is located inside the frame and the eccentric disc is located outside the frame, the drive disc shaft is fixedly connected to the eccentric disc shaft, transmission teeth are provided on both sides of the feeding belt, and incomplete teeth are provided on the edge of the drive disc. The incomplete teeth mesh with the transmission teeth, and driven gears are fixedly connected on both sides of the driven roller. The driven gears mesh with the transmission teeth, so that the rotation of the drive disc can intermittently drive the feeding belt to move, that is, intermittently drive the material-bearing component to move horizontally.

[0022] Furthermore, a transmission rod is hinged to the edge of the eccentric disk, and the other end of the transmission rod is hinged to one side of the moving mold.

[0023] With the above technical solution, since the eccentric disk is hinged to the edge of the transmission rod and the other end of the transmission rod is hinged to one side of the moving mold, the vertical lifting of the moving mold can drive the eccentric disk to rotate through the transmission rod, and the rotation of the eccentric disk can drive the drive disk to rotate.

[0024] The moving die can drive the eccentric disk to rotate once in one cycle of lifting and lowering, which in turn drives the drive disk to rotate once, which in turn drives the material support component to move horizontally once. In other words, the material support component moves horizontally once intermittently in one stamping cycle of the moving die. When the moving die is lowered to stamp, the material support component does not move, so that the stamped spring can fall accurately onto the material support component.

[0025] Furthermore, a fixing plate is fixedly connected to the top center of the frame, and multiple third ventilation slots are provided on the fixing plate. A cleaning component is provided below the fixing plate. The cleaning component includes airbags and a compression frame. There are multiple airbags, and an air jet is provided on the top of each airbag. The air jet is fixedly connected to the bottom of the third ventilation slot. The compression frame is fixedly connected to the bottom of the multiple airbags. The third ventilation slot can overlap with the second ventilation slot.

[0026] With the above technical solution, a fixed plate is fixedly connected to the middle of the top of the frame. Multiple third ventilation slots are provided on the fixed plate. A cleaning component is provided below the fixed plate. The cleaning component includes airbags and a compression frame. There are multiple airbags. The top of the airbags is provided with a jet nozzle. The jet nozzle is fixedly connected to the bottom of the third ventilation slot. The compression frame is fixedly connected to the bottom of the multiple airbags. The third ventilation slot can overlap with the second ventilation slot, so that the compression frame can rise to compress the airbags and make the airbags spray air, and the compression frame can fall to extend the airbags and make the airbags inhale air.

[0027] The jet nozzle is fixedly connected to the bottom of the third ventilation slot. The third ventilation slot can overlap with the second ventilation slot, and the second ventilation slot can overlap with the first ventilation slot. The first ventilation slot is located at the bottom of the receiving slot that accommodates the spring, so that the airbag can blow air into the receiving slot or draw air from the receiving slot.

[0028] Furthermore, the two sides of the compression frame are fixedly connected to the two sides of the moving mold.

[0029] With the above technical solution, since the two sides of the compression frame are fixedly connected to the two sides of the moving mold, the rising of the moving mold can drive the compression frame to rise, that is, compress the airbag and make the airbag release air, and the falling of the moving mold can drive the compression frame to fall, that is, the airbag extends and makes the airbag inhale air.

[0030] During a stamping cycle, the moving die rises, causing the airbag to spray air onto the material-bearing component that has just moved below the stationary die. This air blows air into the receiving groove on the material-bearing component that is not carrying the spring, cleaning the receiving groove and preventing dust and other impurities from affecting the quality of the spring. Meanwhile, the moving die descends to stamp the metal strip to be processed. At this time, the airbag extends and draws air from the receiving groove, which helps the formed spring fall from the groove of the stationary die into the corresponding receiving groove on the material-bearing component.

[0031] The beneficial effects of this invention are as follows:

[0032] (1) In this invention, when the moving mold descends to perform stamping, the material support component does not move. The cutting tool penetrates the pad and the fixed mold, pressing the stamped spring out of the bottom of the fixed mold so that the stamped spring can fall accurately onto the material support component. The material support component is provided with multiple receiving slots corresponding to the groove on the fixed mold, so that the springs falling onto the material support component are arranged in the order of musical notes. The operator will not make installation errors in the subsequent spring installation and fixing process, effectively improving the yield rate.

[0033] (2) In this invention, the vertical lifting of the moving mold can be driven by the transmission rod to drive the eccentric disk to rotate. The rotation of the eccentric disk can drive the drive disk to rotate. The lifting of the moving mold for one cycle can drive the eccentric disk to rotate once, which can drive the drive disk to rotate once, that is, drive the material-bearing component to move horizontally once. This realizes that the material-bearing component moves horizontally once intermittently for one stamping cycle of the moving mold. That is, each material-bearing component only carries one set of springs, which further reduces the installation errors of subsequent springs, facilitates the operation of operators, and improves work efficiency.

[0034] (3) In this invention, the moving mold rises and drives the airbag to spray air, which can spray air onto the material support component that has just moved below the fixed mold, that is, blow air onto the receiving groove on the material support component that does not support the spring, clean the receiving groove, and prevent dust and other impurities in the receiving groove from affecting the quality of the spring. When the moving mold descends to stamp the metal strip to be processed, the airbag extends and draws air from the receiving groove, which can help the formed spring fall from the groove of the fixed mold into the receiving groove on the corresponding material support component, thereby improving production efficiency.

[0048] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0049] like Figure 1 - Figure 2 As shown, a reed stamping die for harmonica production includes a stamping mechanism 1, a die assembly 2, and a feeding mechanism 3. The feeding mechanism 3 is fixedly installed on the ground, the stamping mechanism 1 is fixedly installed on one side of the feeding mechanism 3, the die assembly 2 is installed above the feeding mechanism 3, and a material-bearing component 4 is fixedly installed on the top of the feeding mechanism 3. The stamping mechanism 1 can drive the die assembly 2 to stamp the material to be processed. A drive assembly 5 is rotatably connected to one side of the feeding mechanism 3, and the stamping mechanism 1 can drive the feeding mechanism 3 through the drive assembly 5.

[0050] The material to be processed after being stamped by the mold assembly 2 can fall onto the material receiving component 4 on the material conveying mechanism 3.

[0051] In this embodiment, the mold assembly 2 is provided with clearance grooves that allow metal strips of different pitches to pass through. Pre-made metal strips of different pitches are conveyed to the mold assembly 2 by a feeding device. The stamping mechanism 1 drives the mold assembly 2 to stamp the metal strips of different pitches. The reeds of different pitches formed after stamping fall onto the receiving component 4. The receiving component 4 is provided with receiving grooves for reeds of different pitches corresponding to the mold assembly 2, so that the reeds of different pitches falling onto the receiving component 4 are arranged in order. The operator will not make mistakes in the subsequent reed installation and fixing process, which effectively improves efficiency and reduces installation errors, thereby improving the yield rate. While the stamping mechanism 1 drives the mold assembly 2 to stamp, the driving component 5 drives the conveying mechanism 3 to move, which in turn drives the receiving component 4 to move. This ensures that each stamping operation results in a receiving component 4 without reeds moving to the bottom of the mold assembly 2. That is, each receiving component 4 only carries one set of reeds, which facilitates the subsequent operation of the operator.

[0052] like Figure 2 - Figure 4 As shown, the mold assembly 2 includes a fixed mold 21, a pad 22, a moving mold 23, a buffer spring 24, and a processing frame 25. The processing frame 25 is fixedly set on the ground. The fixed mold 21 is fixedly connected to the processing frame 25. The pad 22 is slidably connected above the fixed mold 21. The moving mold 23 is slidably connected above the pad 22. A punch head is slidably connected to the stamping mechanism 1. The bottom of the punch head is fixedly connected to the top of the moving mold 23.

[0053] A guide post 211 is fixedly connected to the top of the fixed mold 21. The guide post 211 passes through the pad 22 and the moving mold 23. The pad 22 is slidably connected to the guide post 211. The moving mold 23 is slidably connected to the guide post 211. A limit block is fixedly connected to the top of the guide post 211. A guide rod 221 is fixedly connected to the top of the pad 22. The guide rod 221 passes through the moving mold 23. The moving mold 23 is slidably connected to the guide rod 221. A buffer spring 24 is sleeved on the guide rod 221. The bottom of the buffer spring 24 is fixedly connected to the top of the pad 22. The top of the buffer spring 24 is fixedly connected to the bottom of the moving mold 23. A limit plate is fixedly connected to the top of the guide rod 221.

[0054] The bottom of the moving mold 23 is fixedly connected with a cutting tool, which can penetrate the pad 22 and the fixed mold 21.

[0055] In this embodiment, the lifting and lowering of the stamping mechanism 1 can drive the moving mold 23 to lift and lower. When the moving mold 23 descends, it first drives the pad 22 to descend. The descending of the pad 22 can press down the metal strip to be processed. The moving mold 23 drives the cutting tool to continue to descend. The descending cutting tool cooperates with the fixed mold 21 to stamp the metal strip to be processed into a spring sheet.

[0056] There are multiple cutting tools and multiple grooves on the fixed mold 21, which allows multiple reeds of different pitches to be formed in one stamping. The cutting tools can penetrate the pad 22 and the fixed mold 21, so that the cutting tools can press the stamped reeds out of the bottom of the fixed mold 21, thus realizing the discharge of the reeds.

[0057] like Figure 5 - Figure 10 As shown, the material conveying mechanism 3 includes a feeding belt 31, a frame 32 and driven rollers 33. The frame 32 is fixedly connected to the ground, and multiple driven rollers 33 are rotatably connected to the frame 32. The feeding belt 31 is sleeved on multiple driven rollers 33.

[0058] A positioning plate 312 is fixedly connected to the feeding belt 31. Multiple positioning plates 312 are equidistantly arranged on the feeding belt 31. Multiple second ventilation slots 313 are equidistantly arranged on the feeding belt 31. Multiple positioning slots 42 are provided at the bottom of the material receiving component 4. Multiple first ventilation slots 41 are provided at the bottom of the material receiving component 4. The positioning plate 312 can be locked in the positioning slot 42. The second ventilation slots 313 can overlap with the first ventilation slots 41.

[0059] The drive assembly 5 is rotatably connected to the frame 32. The drive assembly 5 includes a drive disk 51 and an eccentric disk 52. The drive disk 51 is located inside the frame 32, and the eccentric disk 52 is located outside the frame 32. The shaft of the drive disk 51 is fixedly connected to the shaft of the eccentric disk 52. The feed belt 31 is provided with transmission teeth 311 on both sides. The edge of the drive disk 51 is provided with incomplete teeth, which mesh with the transmission teeth 311. The driven roller 33 is fixedly connected with driven gears 331 on both sides, which mesh with the transmission teeth 311.

[0060] The edge of the eccentric disk 52 is hinged to a transmission rod 53, and the other end of the transmission rod 53 is hinged to one side of the moving mold 23.

[0061] In this embodiment, multiple material-bearing components 4 can be fixed on the feeding belt 31. Magnets can be installed in the positioning plate 312, and iron sheets can be set in the positioning groove 42. The iron sheets are attracted to the magnets, which makes it convenient for the material-bearing components 4 to be accurately installed on the feeding belt 31.

[0062] The vertical lifting of the moving mold 23 can drive the eccentric disk 52 to rotate via the transmission rod 53. The rotation of the eccentric disk 52 can drive the drive disk 51 to rotate. The rotation of the drive disk 51 can intermittently drive the feeding belt 31 to move, that is, intermittently drive the material-bearing component 4 to move horizontally.

[0063] The moving die 23 can drive the eccentric disk 52 to rotate once in one cycle of lifting and lowering, which in turn drives the drive disk 51 to rotate once, which in turn drives the material support component 4 to move horizontally once. This achieves one stamping cycle of the moving die 23, during which the material support component 4 moves horizontally once intermittently. When the moving die 23 descends to stamp, the material support component 4 does not move, so that the stamped spring can fall accurately onto the material support component 4.

[0064] like Figure 9 - Figure 12 As shown, a fixing plate 321 is fixedly connected to the top center of the frame 32. Multiple third ventilation slots 3211 are provided on the fixing plate 321. A cleaning component 6 is provided below the fixing plate 321. The cleaning component 6 includes airbags 61 and compression frames 62. There are multiple airbags 61. A jet nozzle 611 is provided on the top of the airbag 61. The jet nozzle 611 is fixedly connected to the bottom of the third ventilation slot 3211. The compression frame 62 is fixedly connected to the bottom of the multiple airbags 61. The third ventilation slot 3211 can overlap with the second ventilation slot 313.

[0065] The compression frame 62 is fixedly connected to the two sides of the moving mold 23.

[0066] In this embodiment, the rising of the moving mold 23 can drive the compression frame 62 to rise, that is, compress the airbag 61 and cause the airbag 61 to expel air; the falling of the moving mold 23 can drive the compression frame 62 to fall, that is, the airbag 61 to extend and cause the airbag 61 to inhale air.

[0067] During one stamping cycle, the moving die 23 rises, causing the airbag 61 to spray air onto the material-bearing component 4 that has just moved below the fixed die 21. This air blows air onto the receiving groove on the material-bearing component 4 that is not carrying the spring, cleaning the receiving groove and preventing dust and other impurities from affecting the quality of the spring. Meanwhile, the moving die 23 descends to stamp the metal strip to be processed. At this time, the airbag 61 extends and draws air from the receiving groove, which helps the formed spring fall from the groove of the fixed die 21 into the corresponding receiving groove on the material-bearing component 4.

[0068] Working principle:

[0069] During operation, pre-made metal strips of different pitches are conveyed to the mold assembly 2 through the feeding device, and multiple material-bearing components 4 are fixed on the feeding belt 31.

[0070] Start the stamping mechanism 1. The stamping mechanism 1 drives the moving die 23 to descend. When the moving die 23 descends, it first drives the pad 22 to descend. The descending pad 22 can press down the metal strip to be processed and fix the metal strip to be processed. Then the moving die 23 drives the cutter to continue to descend. The descending cutter cooperates with the fixed die 21 to stamp the metal strip to be processed into a spring.

[0071] There are multiple cutting tools and multiple grooves on the fixed mold 21, which allows multiple reeds of different pitches to be formed in one stamping. After stamping is completed, the moving mold 23 rises to complete one stamping cycle.

[0072] The vertical lifting of the moving mold 23 can drive the eccentric disk 52 to rotate via the transmission rod 53. The rotation of the eccentric disk 52 can drive the drive disk 51 to rotate. The lifting cycle of the moving mold 23 can drive the eccentric disk 52 to rotate once, which means it can drive the drive disk 51 to rotate once, which means it can drive the material support component 4 to move horizontally once. This achieves one stamping cycle of the moving mold 23, and the material support component 4 moves horizontally once intermittently.

[0073] When the moving mold 23 descends to perform stamping, the material support component 4 does not move. The cutting tool penetrates the pad 22 and the fixed mold 21, pressing the stamped spring out of the bottom of the fixed mold 21 so that the stamped spring can fall accurately onto the material support component 4. The material support component 4 is provided with multiple receiving slots corresponding to the groove on the fixed mold 21, so that the springs falling onto the material support component 4 are arranged in musical scale order.

[0074] During one stamping cycle, the moving die 23 rises, causing the airbag 61 to spray air onto the material-bearing component 4 that has just moved below the fixed die 21. This air blows air onto the receiving groove on the material-bearing component 4 that is not carrying the spring, cleaning the receiving groove and preventing dust and other impurities from affecting the quality of the spring. Meanwhile, the moving die 23 descends to stamp the metal strip to be processed. At this time, the airbag 61 extends and draws air from the receiving groove, which helps the formed spring fall from the groove of the fixed die 21 into the corresponding receiving groove on the material-bearing component 4.

[0075] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
