Description

Technical Field

[0001] The present invention belongs to the technical field of stamping equipment, and particularly relates to a reed stamping die for harmonica production. Background Art

[0002] A harmonica is a wind instrument that produces sound by the vibration of reeds. Its core component is the reed, which is usually made by stamping copper strips or stainless steel strips. The thickness and length of the materials used for reeds of different scales are different.

[0003] Therefore, in the traditional harmonica production process, metal strips of different thicknesses need to be prefabricated according to different scales. Then, during the reed processing, reeds of one scale are stamped in the same batch, and then the reeds of one scale are collected uniformly. After that, the die is replaced to stamp the reeds of another scale, or multiple stamping devices are used to produce reeds of different scales. Then, the operator fixes the reeds of different scales on the reed board. After debugging, other accessories are assembled to make a harmonica. This production method has low efficiency. The operator needs to correctly fix the reeds of different scales at different positions on the reed board. Once the position order of one reed is incorrect, the harmonica will be a failure and become a waste product. Summary of the Invention

[0019] 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 die.

[0020] Through the above technical solution, since 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 die, the vertical lifting of the moving die can drive the eccentric disk to rotate through the transmission rod, and the rotation of the eccentric disk can drive the driving disk to rotate; And when the moving die lifts and lowers for one cycle, it can drive the eccentric disk to rotate one week, that is, drive the driving disk to rotate one week, that is, drive the material-carrying component to move horizontally once.

When the moving die descends to stamp the metal strip to be processed, at this time the airbag extends, and the airbag inhales air from the receiving groove, which can help the formed reed to fall from the mold cavity of the fixed die into the corresponding receiving groove on the receiving component.

[0025] The beneficial effects of the present invention are as follows: (1) When the moving die descends for stamping in the present invention, the receiving component does not move, the tool penetrates through the backing plate and the fixed die, and presses the stamped reed out of the bottom of the fixed die, so that the stamped reed can accurately fall on the receiving component. A plurality of receiving grooves corresponding to the mold cavities on the fixed die are provided on the receiving component, so that the reeds falling on the receiving component are arranged in the order of musical scales, and the operator will not make mistakes in the subsequent process of installing and fixing the reeds, effectively improving the yield rate; (2) In the present invention, the vertical lifting of the moving die can drive the eccentric disk to rotate through the transmission rod, the rotation of the eccentric disk can drive the driving disk to rotate, and when the moving die lifts and lowers one cycle, it can drive the eccentric disk to rotate one week, and can drive the driving disk to rotate one week, that is, drive the receiving component to move horizontally once. It realizes that in one stamping cycle of the moving die, the receiving component moves horizontally intermittently once, that is, each receiving component only carries a set of reeds, further reducing the subsequent installation errors of the reeds, facilitating the operation of the operator, and improving the work efficiency; (3) In the present invention, when the moving die ascends, it drives the airbag to jet air, which can jet air to the material receiving component that has just moved below the fixed die, that is, blow air into the receiving groove on the material receiving component that does not carry the reed, clean the receiving groove, and prevent impurities such as dust in the receiving groove from affecting the quality of the reed. When the moving die descends to stamp the metal strip to be processed, at this time, the airbag expands, and the airbag inhales air from the receiving groove, which can help the formed reed to fall from the mold cavity of the fixed die into the corresponding receiving groove on the material receiving component, improving production efficiency.

The rotation of the driving disk 51 can intermittently drive the feeding belt 31 to move, that is, intermittently drive the material receiving components 4 to move horizontally; And one cycle of the lifting of the moving die 23 can drive the eccentric disk 52 to rotate one week, that is, drive the driving disk 51 to rotate one week, that is, drive the material receiving components 4 to move horizontally once, realizing one stamping cycle of the moving die 23 and the material receiving components 4 intermittently move horizontally once. When the moving die 23 descends for stamping, the material receiving components 4 do not move, so that the stamped reed can accurately fall on the material receiving components 4.

[0035] Such as Figure 9 - Figure 12 As shown in the figure, a fixing plate 321 is fixedly connected to the middle of the top of the frame 32.

[0037] Working principle: During operation, the prefabricated metal strips of different scales are conveyed to the die assembly 2 through the feeding device, and a plurality of material receiving components 4 are fixed on the feeding belt 31; Start the stamping mechanism 1. When the stamping mechanism 1 drives the moving die 23 to descend, when the moving die 23 descends, it first drives the backing plate 22 to descend. The descent of the backing plate 22 can press the metal strip to be processed and fix the metal strip to be processed. Then the moving die 23 drives the cutter to continue descending. The descent of the cutter cooperates with the fixed die 21 to stamp the metal strip to be processed into a reed; There are multiple cutters, and there are multiple mold cavities corresponding to the fixed die 21, so that multiple reeds of different scales can be formed in one stamping. After stamping is completed, the moving die 23 rises to complete a stamping cycle; The vertical lifting of the moving die 23 can drive the eccentric disk 52 to rotate through the transmission rod 53.

The cutter penetrates through the backing plate 22 and the fixed die 21, and presses the stamped reed out of the bottom of the fixed die 21, so that the stamped reed can accurately fall on the material receiving component 4. There are multiple receiving grooves on the material receiving component 4 corresponding to the mold cavities on the fixed die 21, realizing the reeds falling on the material receiving component 4 being arranged in the order of scales; During a stamping cycle, the moving die 23 rises, driving the airbag 61 to jet air, which can jet air at the material receiving component 4 that has just moved below the fixed die 21, that is, blow air into the receiving groove on the material receiving component 4 that does not carry the reed, clean the receiving groove, and prevent impurities such as dust in the receiving groove from affecting the quality of the reed. Then the moving die 23 descends to stamp the metal strip to be processed. At this time, the airbag 61 expands, and the airbag 61 sucks air from the receiving groove, which can help the formed reed fall from the mold cavity of the fixed die 21 into the corresponding receiving groove on the material receiving component 4.
