Sliding grooves 2 are respectively opened inside the two support columns 1. A first mounting block 3 is slidably fitted inside each sliding groove 2. An installation tube 4 is fixedly arranged in the middle of each first mounting block 3. A first shaping cylinder 5 for cooperative bending and shaping is fixedly arranged in the middle of the surface of each installation tube 4. The radian of the horizontal bending is adjusted by controlling the distance between the two first shaping cylinders 5. A support shaft 6 is rotatably connected inside each installation tube 4 for angle adjustment. A connecting arm 7 is fixedly arranged at one end of each support shaft 6 for providing connection support. A pressing block 8 is arranged at one end of each connecting arm 7. The two ends of the earphone steel strip are pressed and shaped by the pressing block 8. An adjusting component 10 is arranged between the two support columns 1;

[0025] A first mounting seat 31 is fixedly arranged on one side of each of the two support columns 1. A first electric cylinder 32 is fixedly arranged in the middle of each first mounting seat 31. The telescopic ends of the two first electric cylinders 32 are respectively fixedly connected with one end of the two first mounting blocks 3. The distance between the two first mounting blocks 3 is adjusted by controlling the length of the telescopic end of the first electric cylinder 32;

[0026] Motor seats 61 are fixedly arranged on the back of the two installation tubes 4. Reducing motors 62 are fixedly arranged on the surfaces of the two motor seats 61. The transmission shafts of the two reducing motors 62 are respectively fixedly connected with the other ends of the two support shafts 6;

[0027] A connecting groove 41 for the sliding fit of the installation tube 4 is opened on the surface of each support column 1;

[0028] Fixed seats 111 are fixedly arranged at the bottom ends of the two support columns 1. Fixing holes 112 are opened at the four corners of each fixed seat 111. A fixing rod 113 is fixedly arranged between the two fixed seats 111;

[0029] Placing seats 1001 are fixedly arranged on one side of the surfaces of the two support columns 1. A placing groove 1002 is opened in the middle of each placing seat 1001 for placing the earphone steel strip;

[0030] Specifically, first, the placing groove 1002 in the middle of the placing seat 1001 provides an auxiliary positioning function for placing the earphone steel strip. The headband earphone steel strip to be processed is placed between the first shaping cylinder 5 and the pressing block 8. The staff controls the length of the telescopic end of the first electric cylinder 32 to adjust the distance between the two first mounting blocks 3. When the first mounting block 3 moves, it will drive the installation tube 4 and the first shaping cylinder 5 to move synchronously, so as to control the radian turning point of the earphone metal steel strip in the horizontal direction.

[0031] Embodiment 2:

[0032] The adjusting component 10 includes a connecting column 101. The connecting column 101 is fixedly arranged between two support columns 1. At the top of the back surface of the connecting column 101, a second mounting seat 102 is fixedly arranged. In the middle of the second mounting seat 102, a second electric cylinder 103 is fixedly arranged. The telescopic end of the second electric cylinder 103 is fixedly provided with a second mounting block 104 through a connecting block. At one end of the second mounting block 104, a second shaping cylinder 105 for cooperating with bending and shaping is fixedly arranged.

[0033] An adjusting groove 106 matching the second mounting block 104 is formed in the middle of the connecting column 101. The adjusting groove 106 is used to cooperate with the second mounting block 104 for sliding.

[0034] Specifically, first, the staff starts the second electric cylinder 103. The second electric cylinder 103 drives the second mounting block 104 and the second shaping cylinder 105 to move synchronously through its telescopic end, so that the second shaping cylinder 105 presses on the middle part of the metal steel band of the headband-type earphone, causing the middle part of the earphone metal steel band to be bent and deformed.

[0035] During use, first, the curvature-adjustable earphone headband bending machine is carried to a suitable position through the fixing seat 111, and is locked and fixed with the lower part of the external bolt through the fixing hole 112 at the corner of the fixing seat 111. The fixing rod 113 makes the connection between the two fixing seats 111 more firm. In order to flexibly adjust the horizontal curvature and vertical curvature of the metal steel band of the headband-type earphone, the metal steel band of the headband-type earphone to be processed is placed between the first shaping cylinder 5 and the pressing block 8. The placing groove 1002 in the middle of the placing seat 1001 provides an auxiliary positioning function for the placement of the earphone steel band, and at the same time makes the metal steel band of the headband-type earphone not easy to fall off. After the placement is completed, the staff starts the second electric cylinder 103. The second electric cylinder 103 drives the second mounting block 104 and the second shaping cylinder 105 to move synchronously through its telescopic end, so that the second shaping cylinder 105 presses on the middle part of the metal steel band of the headband-type earphone, causing the middle part of the earphone metal steel band to be bent and deformed. The staff can adjust the curvature in the longitudinal direction of the steel band by controlling the length of the telescopic end of the second electric cylinder 103, and the adjustment method is more flexible.

[0036] In order to flexibly adjust the horizontal arc of the metal steel belt of the headband-type earphone, a slidable first mounting block 3 is arranged inside each of the two support columns 1 through a chute 2. The staff controls the length of the telescopic end of the first electric cylinder 32, and the two first mounting blocks 3 move relatively or in opposite directions. When the first mounting block 3 moves, it will drive the mounting tube 4 and the first shaping cylinder 5 to move synchronously, thereby controlling the turning point of the horizontal arc of the earphone metal steel belt. The staff controls the forward and reverse rotation of the transmission shafts of the two reduction motors 62, so that the pressing block 8 connected by the support shaft 6 through the connecting arm 7 presses on the surface of the earphone steel belt, causing the earphone steel belt to bend and deform along the outer surface contour of the first shaping cylinder 5, and the control method is more flexible.

[0037] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
