[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0024] Referring to Figure 2 - Figure 4 As shown in the utility model provides an embodiment: a special spring manufacturing jig for bracelet hinge position, including base 1, base 1 top end fixedly connected with guide table 2, guide table 2 inner wall is provided with steel bar 3, base 1 top end rear side fixedly connected with motor 5, motor 5 drive end is provided with processing assembly, processing assembly includes the processing table 4 of fixedly connected in base 1 top end left side, the inner wall of processing table 4 is installed with axle 7, axle 7 front end fixedly connected with protruding block 8, axle 7 and protruding block 8 are left with a certain distance, motor 5 drive end fixedly connected with screw rod 6, screw rod 6 outer wall is connected in the inner wall of axle 7 with screw thread, to be used for the manufacture and processing of special spring.

[0025] Specifically, axle 7 and protruding block 8 are left with a certain distance, can make steel bar 3 insert into the bending processing between axle 7 and protruding block 8, through motor 5 drive steel bar 3 rotation, do not need to manually bend steel bar 3, the special spring production process is fast and convenient, and the special spring produced can be adapted to various sizes of opening bracelet hinge position, and automatic production can be realized by means of machine table automatic conveying, the dependence on a large number of manual operation is reduced, the production cost is reduced, and the production efficiency is improved.

[0026] Referring to Figure 1 and Figure 5 As shown in the utility model provides an embodiment: a special spring manufacturing jig for bracelet hinge position, including base 1, base 1 top end fixedly connected with guide table 2, guide table 2 inner wall is provided with steel bar 3, base 1 top end rear side fixedly connected with motor 5, motor 5 drive end is provided with processing assembly, processing assembly includes the processing table 4 of fixedly connected in base 1 top end left side, the inner wall of processing table 4 is installed with axle 7, axle 7 front end fixedly connected with protruding block 8, axle 7 and protruding block 8 are left with a certain distance, motor 5 drive end fixedly connected with screw rod 6, screw rod 6 outer wall is connected in the inner wall of axle 7 with screw thread, to be used for the manufacture and processing of special spring.

[0027] Specifically, in each processing, push or replace the steel bar 3, need to move or insert the steel bar 3 in the through hole, for the steel bar 3 is inserted between the shaft 7 and the protruding block 8, a fixed block is fixedly connected on the left side of the front end of the processing table 4, and the steel bar 3 needs to be pushed to the right side of the fixed block in each pushing process. The steel bar 3 passes through the through hole and is close to the top end of the guide table 2 during bending and dividing. Then start the motor 5 to bend and process, so that workers can easily and quickly complete clamping, debugging and processing operations, reduce labor intensity and improve work efficiency. In addition, during bending, the operator should wear necessary personal protective equipment to prevent hand injury and protect the eyes from flying objects when the steel bar breaks.

[0028] Working principle: first, manually push the steel bar 3 to the left, move the steel to the left side of the protruding block 8, and then start the motor 5. The motor 5 drives the screw rod 6 to rotate, and the screw rod 6 drives the shaft 7 to rotate. First, the shaft 7 rotates ninety degrees and retreats by means of the motor 5, so that the left side of the steel bar 3 is raised upward. The shaft 7 continues to rotate two hundred and seventy degrees and retreats by means of the motor 5, so that one side of the steel bar 3 rotates downward. The shaft 7 rotates three hundred and ninety-six degrees and retreats by means of the motor 5, so that the steel bar 3 is bent one turn. Manually pull down the lever 10, the lever 10 drives the dividing block 11 to move downward, and the dividing block 11 cuts off the steel bar 3. Thus, the special spring is made, the special spring is taken out, and the next step of processing is performed again. After the dividing is completed, the steel rod 10 and the dividing block 11 are restored to the original position by the dividing spring 12.
