After the workpiece with the wire wound is placed on the positioning seat 150, the positioning mechanism 200 can position and fix the workpiece, so as to ensure that the relative position between the workpiece and the positioning seat 150 is determined, and avoid the problem of shaking or moving of the workpiece during the processing. Subsequently, the line straightening mechanism 500 can move closer to the positioning seat 150 and adjust the relative position between the line foot and the positioning seat 150, thereby ensuring that the relative position between the line foot and the positioning seat 150 is determined. Finally, the line pressing mechanism 300 can move closer to the positioning seat 150 and perform extrusion shaping between the positioning seat 150 and the line foot, thereby completing the molding operation of the line foot of the workpiece. By adjusting and positioning the workpiece and the line foot respectively through the positioning mechanism 200 and the line straightening mechanism 500, it can be effectively ensured that when the line pressing mechanism 300 performs extrusion shaping, the workpiece and the line foot are both in the predetermined position, thereby ensuring that the molding operation can be carried out smoothly and stably, thereby effectively improving the yield rate of the line foot molding operation.

In some embodiments, referring to FIG. 3 , the positioning seat 150 is provided with a positioning groove 175, and the positioning groove 175 is used to position the workpiece on the positioning seat 150; the positioning mechanism 200 includes a fixed frame 250 movably connected to the machine table 100, and the fixed frame 250 can move close to the positioning groove 175 and clamp the workpiece in the positioning groove 175. After the fixed frame 250 moves close to the positioning seat 150, the fixed frame 250 can cooperate with the positioning seat 150 to clamp the workpiece in the positioning groove 175. The positioning groove 175 is used to relatively position the workpiece and the positioning seat 150, and the fixed frame 250 is used to relatively fix the positioned workpiece, so that the positioning and fixing effect of the workpiece can be effectively achieved, so that the workpiece can be accurately carried out for the molding operation, and it is not easy to have problems such as shaking during the operation, so as to ensure that the operation can be carried out smoothly and stably.

Specifically, the positioning groove 175 is an arc-shaped groove adapted to the shape of the core. Of course, the positioning groove 175 can also be in other shapes, such as being set in a buckle shape and fastening and installing the workpiece. Therefore, the specific implementation of the positioning groove 175 is not unique, but can be adjusted accordingly according to actual conditions, and is not limited here.

Furthermore, the machine 100 is provided with a driving cylinder 210, which is connected to the fixing frame 250 and can drive it to descend close to the positioning seat 150 or to rise away from the positioning seat 150. Of course, the fixing frame 250 can also be driven by other components, and the specific implementation method can be adjusted accordingly according to actual needs, which is not limited here.

In some embodiments, referring to FIG. 5 , the fixing frame 250 is provided with a fixing groove 255. When the fixing frame 250 moves close to the positioning groove 175, the fixing groove 255 and the positioning groove 175 can cooperate to surround the workpiece. The fixing groove 255 and the positioning groove 175 respectively position the workpiece, so that the workpiece can effectively achieve the relative positioning effect between it and the fixing frame 250 and the positioning seat 150. In addition, the fixing groove 255 and the positioning groove 175 can cooperate to cover the workpiece, so that the workpiece is fully positioned and fixed to the positioning seat 150, thereby effectively avoiding the problem of shaking or moving of the workpiece during the molding process.

Specifically, the fixing groove 255 is an arc-shaped groove adapted to the shape of the iron core, the positioning groove 175 opens upward, and the fixing groove 255 opens downward. Of course, the fixing groove 255 can also be in other shapes, such as being set in a buckle shape and fastening and installing the workpiece. Therefore, the specific implementation method of the positioning groove 175 is not unique, but can be adjusted accordingly according to actual conditions, and is not limited here.

In certain embodiments, referring to FIG. 2 , the line straightening mechanism 500 includes a driving device 400 and a forming clamp 530. The driving device 400 is connected to the forming clamp 530 and is used to drive the forming clamp 530 to move closer to or away from the positioning seat 150; the forming clamp 530 can push and form the line foot of the workpiece. After the driving device 400 is started, it can drive the forming clamp 530 to move closer to the positioning seat 150, and push the line foot through the forming clamp 530, so that the line foot is initially formed to a predetermined position, thereby facilitating the subsequent line pressing mechanism 300 to further form the line foot. Since the line foot is pre-formed by the forming clamp 530 before the final forming of the line foot, it can effectively ensure that the line foot is in a predetermined position before the final forming operation, thereby improving the forming effect and yield rate of the line pressing mechanism 300.

In some embodiments, referring to FIG. 4 , there are two forming clamps 530 and they are respectively located on both sides of the positioning seat 150. Both forming clamps 530 are provided with rollers 540 for applying forming pressure to the wire feet. The rollers 540 can follow the movement of the forming clamps 530 and roll the wire feet onto the positioning seat 150. The iron core of the inductor will have two wire feet extending outward, and the two wire feet are respectively used for connecting the positive and negative electrodes in the electrode. When the workpiece is placed on the positioning seat 150, the two wire feet on the workpiece will be able to extend to both sides of the positioning seat 150 respectively. The two forming clamps 530 can respectively perform preliminary forming operations on the two wire feet from both sides of the positioning seat 150, thereby achieving a synchronous forming effect of the two wire feet, thereby effectively improving the operating efficiency of the forming operation.

It is conceivable that there may be only one molding clamp 530 and only one molding foot or molding feet located on the same side of the positioning seat 150 may be processed. The specific implementation method may be adjusted accordingly according to actual needs and is not limited here.

In some embodiments, referring to FIG. 3 , the positioning seat 150 is provided with a thread foot groove 173, the roller 540 is used to roll the thread foot into the thread foot groove 173, and the wire pressing mechanism 300 is used to extrude and shape the thread foot in the thread foot groove 173. The thread foot groove 173 can limit the position of the thread foot. When the thread foot is pushed into the thread foot groove 173 by the roller 540, the thread foot will be subject to the position limiting effect of the thread foot groove 173, thereby effectively ensuring that the thread foot is always at a predetermined position during the subsequent processing of the thread pressing mechanism 300, thereby improving the accuracy of the processing operation of the thread pressing mechanism 300.

In some embodiments, referring to FIG. 6 , the forming clamp 530 is provided with an inclined portion 550, and the inclined portion 550 has an inclined surface for guiding the line foot; when the driving device 400 drives the forming clamp 530 to move close to the positioning seat 150, the inclined portion 550 can push the line foot into the line foot groove 173 through the inclined surface. In the process of the forming clamp 530 gradually approaching the positioning seat 150, the inclined portion 550 will first contact the line foot. In the process of the continuous contact between the inclined portion 550 and the line foot, the inclined portion 550 will push the line foot, so that the line foot moves toward the normal direction of the inclined surface, and finally falls into the line foot groove 173, so as to facilitate the subsequent forming operation of the line foot by the wire pressing mechanism 300.

Specifically, the driving device 400 is a cylinder, which is connected to the forming clamp 530 and can drive the forming clamp 530 to descend close to the positioning seat 150 or to ascend away from the positioning seat 150. The lower surface of the inclined portion 550 gradually inclines to the left from bottom to top.

In some embodiments, referring to FIG. 3 , the machine 100 is provided with a first slide rail set 570, and the forming clamp 530 is slidably connected to the machine 100 through the first slide rail set 570 and can slide up and down relative to the positioning seat 150. The first slide rail set 570 can not only guide the relative sliding between the forming clamp 530 and the machine 100, but also effectively limit the direction of the relative movement between the two, thereby effectively ensuring that the forming clamp 530 can smoothly and effectively perform preliminary forming operations on the molding feet on the workpiece.

Specifically, a second slide rail set 270 is disposed on the machine platform 100 , and the fixing frame 250 is slidably connected to the machine platform 100 via the second slide rail set 270 .

In some embodiments, referring to FIG. 2 , the wire pressing mechanism 300 includes a wire pressing cylinder 350, which is located beside the positioning seat 150 and can push the wire foot against the side wall of the positioning seat 150. After the wire pressing cylinder 350 is started, its output end will move close to the positioning seat 150 and push the wire foot against the positioning seat 150, so that the wire foot can be compacted, and then the molding operation of the wire foot can be successfully completed.

It is conceivable that the wire pressing mechanism 300 may also be composed of other components, such as the cooperation between the motor and the screw, and the end of the screw is used to spin the wire foot. Therefore, the specific implementation method of the wire pressing mechanism 300 is not unique, but can be adjusted accordingly according to actual conditions, and is not limited here.

In certain embodiments, referring to FIG. 2 , there are two wire pressing cylinders 350, which are respectively located on both sides of the positioning seat 150 and can respectively push the wire feet on both sides of the workpiece against the two sides of the positioning seat 150. The iron core of the inductor will have two wire feet extending outward, and the two wire feet are respectively used for connecting the positive and negative electrodes in the electrode. When the workpiece is placed on the positioning seat 150, the two wire feet on the workpiece can extend to both sides of the positioning seat 150. The two wire pressing cylinders 350 can respectively perform the pressing and compacting operations on the two wire feet from both sides of the positioning seat 150, thereby directly and effectively completing the forming process of the wire feet. In addition, since the forming operation is performed on the two wire feet at the same time, the operating efficiency can also be effectively increased, and the effect of improving efficiency can be brought about.

The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
