Description

Technical Field

[0001] The invention relates to the technical field of audio accessory processing, in particular to an audio hook bending and assembling integrated processing device. Background Art

[0002] The audio hook is an accessory for hanging audio equipment, usually used for small audio equipment such as portable Bluetooth speakers. When processing the audio hook, it is first necessary to cut a rod of suitable length, then bend the rod through a mold, and then flatten the two ends of the rod after bending, so that a flat connection is formed at both ends of the rod, and then drill holes on the connection and assemble the lock column of the hook. In the prior art, when bending the rod, the rod is directly bent into the shape of a hook by applying pressure to the rod at one time and matching the corresponding mold. The one-time molding of the hook requires that both the rod and the mold can withstand a large pressure, and the quality of the rod and the mold are both high. When the rod and the mold are subjected to large pressure, they are prone to wear, especially the mold. Under long-term high pressure, the molding groove on its surface will be flattened or concave.

The hydraulic mechanism 5 drives the flattening upper die 102 to move downward and squeeze it on the flattening lower die 101, so that the rod between the upper and lower dies is processed into a required shape.

[0053] See also Figures 17 to 19 The rod 63 is bent twice by the primary bending mechanism 8 and the secondary bending mechanism 9 to form a waist-shaped hook body 13. The hook body 13 is transported to the end flattening mechanism 10 through the cooperation of the feeding mechanism 2 and the manipulator on the third platform 4. The two ends of the hook body 13 are flattened by the end flattening mechanism 10 to form flat ends 131. The flat ends 131 are connecting parts for installing the lock column on the hook. The flattened hook body 13 is sent to the drilling mechanism 11 through the material moving mechanism 7. One of the flat ends 131 is drilled by the drilling mechanism 11. After drilling, it is sent to the assembly mechanism 12 through the material moving mechanism 7 for assembly. During assembly, the prepared lock column 14 is sleeved between the two flat ends 131, and then the pin 15 is nailed into the drilled hole through the assembly mechanism 12 to complete the assembly of the lock column 14 and the hook body 13.

[0054] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
