Technical Field

[0001] This utility model relates to the field of diaphragm processing technology, and more specifically to an automatic diaphragm cutting device. Background Technology

[0002] Diaphragms are usually thin sheets made in a circular or elliptical shape. They are attached to the speaker with adhesive, and the diaphragm is driven to vibrate at different frequencies according to changes in the current. This causes the air to vibrate and produce sound, thus amplifying and transmitting the sound.

[0003] During the production of the diaphragm, a flat sheet is pressed into the required shape using a mold, and then cut to form a circular or elliptical sheet.

[0004] During the diaphragm cutting process, the die drives the blade to cut the sheet. However, the sheet is thin, so under the instantaneous impact pressure, it is easy for the sheet to deform or for the cut to be uneven. This greatly increases the probability of waste in the diaphragm production process, thus affecting the diaphragm production efficiency. Utility Model Content

[0030] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0031] like Figure 1-6 As shown, an automatic diaphragm cutting device includes a sheet 5 and a forming part 51 disposed on the sheet 5, and further includes an upper mold base 1 and a lower mold base 6. A pad 7 and a stamping plate 2 are disposed between the upper mold base 1 and the lower mold base 6 in sequence. A blade 25 facing the forming part 51 is disposed on the stamping plate 2.

[0032] Among them, the pad 7 is provided with a cutting part 71, the cutting part 71 is provided with a support plate 73, the support plate 73 is slidably provided with a top plate 74 that fits against the forming part 51, the cutting part 71 is provided with a transmission unit 72 that cooperates with the top plate 74, and the transmission unit 72 cooperates with the stamping plate 2.

[0033] The transmission unit 72 controls the top plate 74 to slide on the support plate 73 so that the top surface of the top plate 74 fits into the molding part 51;

[0034] Guide rod 4 is disposed between pad 7 and upper mold base 1. A second spring 3 is provided on guide rod 4 to cooperate with stamping plate 2. Stamping plate 2 slides on guide rod 4 to control the blade 25 to move closer to or away from forming part 51.

[0035] Specifically, a sliding rod is provided on the upper mold base 1, and an external cylinder is connected to the sliding rod. The external cylinder controls the stamping plate 2 to slide on the guide rod 4. The pad 7 is fixed to the lower mold base 6 by bolts. When cutting the forming part 51, the external cylinder drives the stamping plate 2 to slide on the guide rod 4 to compress the first spring 22. The stamping plate 2 slides until the blade 25 contacts the forming part 51 to complete the cutting. At this time, the compressed first spring 22 pushes the stamping plate 2 to slide upward at the guide rod 4 so that the stamping plate 2 returns to the initial state.

[0036] During the stamping process, the stamping plate 2 will be linked with the transmission unit 72. The transmission unit 72 controls the top plate 74 to contact the forming part 51, giving the forming part 51 a certain resistance effect, so that the cut surface of the forming part 51 is flatter and the phenomenon of damage to the forming part 51 is reduced.

[0037] Furthermore, after the cutting is completed, the operation of the cylinder 75 on the pad 7 drives the unloading block 751 to push the diaphragm of the cutting plate onto the cutting section 71. The cylinder 75 is fixed to one side of the cutting section 71 by the fixing bracket 752. One side of the cutting section 71 is the discharge side, and an inclined part 711 is provided on its adjacent side to improve the bonding effect between the pad 7 and the sheet 5.

[0038] As a further embodiment of this utility model, the transmission unit 72 includes a slide 721, a connecting rod 722, a slider 729, a gear 724, a support base 723, and a push rod 726 slidably disposed on the support base 723. The push rod 726 engages with the top plate 74. The gear 724 is rotatably connected to the support base 723 and meshes with the push rod 726 and the slider 729. The slider 729 is slidably disposed on the support base 723. The slide 721 is slidably connected to the cutting part 71 and cooperates with the transmission unit 72. The connecting rod 722 is engaged with the slider 729 and the slide 721. Between them, the two ends of the connecting rod 722 are fixed to the slide 721 and the slider 729 respectively. This allows the slide 721 to slide against the slider 729 on the support seat 723 when it slides. During the downward sliding of the stamping plate 2, it will push the slide 721 to slide downward at the cutting part 71, so as to drive the slider 729 to slide on the support seat 723 through the connecting rod 722. At the same time, the gear 724 rotates on the support seat 723 to drive the push rod 726 to push the top plate 74 close to and attach to the lower plane of the molding part 51, so as to provide a certain support effect to the molding part 51.

[0039] As a further embodiment of this utility model, a slide groove 725 is provided on the support base 723, and a slider 729 is disposed on the slide groove 725. A toothed groove is provided on one side of the slider 729. The slide groove 725 serves as a limiting effect to restrict the sliding distance of the slider 729.

[0040] As a further embodiment of this utility model, one end of the push rod 726 is provided with a third spring 727 that cooperates with the support base 723, and the push rod 726 is provided with a toothed portion 728. The third spring 727 pushes the push rod 726 to slide downward on the support base 723.

[0041] As a further embodiment of this utility model, a support plate 26 is provided on the stamping plate 2, and a triangular locking block 261 is provided on the support plate 26. The blade 25 is fixed to the support plate 26 by the triangular locking block 261. After the blade 25 has been used for a long time, the blade 25 can be removed from the support plate 26 for replacement. The triangular locking block 261 is used to improve the support effect on the blade 25.

[0042] As a further embodiment of this utility model, a tilting block 21 is provided on the stamping plate 2, a guide seat 23 is slidably provided on the tilting block 21, a roller 24 is rotatably provided on the guide seat 23, and a first spring 22 is provided between the guide seat 23 and the tilting block 21. During the stamping process of the sheet 5, the roller 24 contacts the sheet 5 before the blade 25. As the stamping plate 2 gradually slides downward, it will squeeze the first spring 22. Under the elastic push of the first spring 22, the roller 24 continuously supports the sheet 5, so that the forming part 51 located under the stamping plate 2 is tensioned to make it flat, thereby improving the cutting effect of the diaphragm.

[0043] As a further embodiment provided by this utility model, a limiting block 27 is engaged on the stamping plate 2. The height of the limiting block 27 is less than the height of the blade 25, and the limiting block 27 cooperates with the slide 721. When the stamping plate 2 slides downward, the limiting block 27 will push the slide 721 to slide on the cutting part 71.

[0044] As a further embodiment provided in this utility model, the diameter of the top plate 74 is smaller than the diameter of the blade 25, and the cutting position of the blade 25 is as follows: Figure 5 As shown by the dashed line in the middle molding section 51, the diameter of the opposite top plate 74 is smaller than the diameter of the molding section 51.

[0045] As a further embodiment provided by this utility model, a shim block 62 is provided on the lower mold base 6. The shim block 62 cooperates with the pad 7. The shim block 62 has multiple mounting holes. The pad 7 is fixed to the top of the lower mold base 6 through the mounting holes. The shim block 62 is also provided to provide mounting space for the transmission unit 72.

[0046] As a further embodiment of this utility model, both the upper mold base 1 and the lower mold base 6 are provided with hand-held grooves 11, which have arc-shaped portions to facilitate manual hand-held transport or assembly operations of the upper mold base 1 or the lower mold base 6.

[0047] Working principle: The sheet 5 is placed on the cutting part 71, so that the forming part 51, the top plate 74 and the blade 25 are highly concentric. Then, the external cylinder controls the stamping plate 2 to slide on the guide rod 4, so that the blade 25 contacts the forming part 51 to complete the cutting. In addition, during the downward sliding of the stamping plate 2, the limit block 27 pushes the slide 721 to slide downward on the cutting part 71, so that the connecting rod 722 drives the slider 729 to slide on the support seat 723. This causes the gear 724 to link with the push rod 726, so that the push rod 726 slides upward on the support seat 723, thereby pushing the top plate 74 to fit against the lower plane of the forming part 51. This reduces the damage to the forming part 51 under instantaneous stamping and improves the production efficiency of the diaphragm.

[0048] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.
