The arc-shaped die 41 has an L-shaped groove 43 on its middle side, and the arc-shaped punch 42 has an L-shaped protrusion 44 fixedly installed on its middle side.

[0034] The arc-pressing die 41 and the arc-pressing punch 42 are combined to press the steel wire into an arc shape. The arc shape and the steel wire body form a fixed angle. The arc shape and the angle are integrally formed, and the angle is 100 degrees.

[0035] Example 2: In some embodiments, such as Figures 1-11A continuous wire pressing arc device includes: a frame 1, and further includes: a rotating wire feeding mechanism 2, a driving mechanism 3 and an arc pressing mechanism 4. The rotating wire feeding mechanism 2 is installed on the rear side of the frame 1, and the four driving mechanisms 3 are distributed in a circumferential array at equal intervals on the frame 1. The arc pressing mechanism 4 is installed on the driving mechanism 3.

[0036] The rotary wire feeding mechanism 2 is used to periodically and quantitatively feed steel wire, and the drive mechanism 3 is used to drive the arc-forming mechanism 4 to move, so as to bend the steel wire of a specific length fed by the rotary wire feeding mechanism 2 into an L-shape for subsequent processing to make a snap ring.

[0037] The driving mechanism 3 includes: a support frame 31, a guide rail 32, a slider 33, and a movable bracket 34. The support frame 31 is fixedly installed on the upper side of the frame 1. The two guide rails 32 are fixedly installed on the support frame 31. The slider 33 is slidably connected to the guide rail 32. The movable bracket 34 is fixedly installed on the slider 33.

The housing of the first servo motor 37 is fixedly mounted on the support frame 31, and the output shaft of the first servo motor 37 is fixedly connected to the input end of the first gearbox 35.

[0040] The first servo motor 37 of the drive mechanism 3 rotates, causing the input end of the first gearbox 35 to rotate. The rotation of the input end of the first gearbox 35 causes the output end of the first gearbox 35 to rotate. The rotation of the output end of the first gearbox 35 causes the connecting rod 36 to rotate and move simultaneously. The connecting rod 36 moves towards the center of the frame 1, causing the moving bracket 34 to move towards the center of the frame 1. The guide rail 32 and the slider 33 are used to limit the movement of the moving bracket 34.

[0041] The drive mechanism 3 further includes a spring-back assembly, which is installed on one end of the connecting rod 36 near the movable bracket 34.

[0046] The steel wire is placed between the two guide wheels 22 of the rotating wire feeding mechanism 2. Then, the steel wire is moved forward, passes through the electric chuck 25, and enters the circular opening 29 of the rotating frame 24. After the steel wire is placed, the output end of the fourth servo motor 23 rotates, driving the guide wheel 22 to rotate. The rotation of the guide wheel 22 drives the steel wire to move forward a preset distance. The electric chuck 25 starts to clamp the steel wire. The output shaft of the third servo motor 26 rotates, driving the main gear 27 to rotate. The rotation of the main gear 27 drives the drive gear 28 to rotate.
