Such a structure enables the edge of the first dividing groove 104 to be perfectly connected with the edge of the second dividing groove 105 during the molding process of the product, forming a complete and solid cylindrical structure.

[0057] In order to form the above-mentioned metal terminal 1, the embodiment of the present application discloses a metal terminal production line. Figure 3 The metal terminal production line includes a feeding mechanism 14, a mold clamping machine 15, a material receiving mechanism 16 and a waste material reeling mechanism 17 which are sequentially arranged along the conveying direction of the material strip. These mechanisms cooperate with each other to jointly complete the production process of the metal terminal 1.

[0058] Continue to refer to Figure 3 First, the feeding mechanism 14 includes a base 141 and a turntable 142, the turntable 142 is rotatably connected to the base 141, and the turntable 142 is used to wind the material strip and transmit the material strip to the mold clamping machine 15.

[0059] Continue to refer to Figure 3 Next, the mold clamping machine 15 is the core part of the production line, on which a mold is set to complete the main molding process of the metal terminal 1. The mold includes a fixed mold 2 and a movable mold 3. The fixed mold 2 is fixed on the mold clamping machine 15, and the movable mold 3 moves up and down through a lifting drive mechanism.

The number of the punching mechanisms 4 can be one or more, and the shapes of each first punch 41 and the first slot 42 are different, which are used to punch holes of different shapes on the material strip. When the metal terminal 1 forming mold is closed, the first punch 41 moves downward under power drive and accurately docks with the first slot 42, thereby punching out a preset hole position on the material strip. Multiple punching mechanisms 4 with different shapes can operate on the material strip at the same time, which greatly improves the punching efficiency and flexibility.

[0062] Reference Figure 7 and Figure 8 , followed by a grille slot forming mechanism 5, which includes a plurality of second punches 51 and second punching slots 52 (combined Fig. 9 ), a plurality of the second punches 51 are fixed on the movable die 3, and the second punching slots 52 are opened on the fixed die 2.

The wire clamping groove 102 further increases the aesthetics of the metal terminal 1.

[0064] Reference Figure 1 and Figure 5 Next is the separation groove forming mechanism 7, which includes a first groove forming component 71 and a second groove forming component 72.

The first pressing block 711 is fixed on the movable mold 3, and the first groove 712 is provided on the fixed mold 2. The first pressing block 711 is plugged into and matched with the first groove 712. The shapes of the first pressing block 711 and the first groove 712 are both adapted to the shape of the first separation groove 104. During the closing process of the metal terminal 1 forming mold, the first pressing block 711 moves downward and matches with the first groove 712 to accurately press out the shape of the first separation groove 104 on the material strip.

[0066] Reference Fig.12 and Fig.13 The second groove forming assembly 72 includes a second pressing block 721 and a second groove 722, the second groove 722 is arranged on the movable mold 3, and the second groove 722 is opened on the fixed mold 2 (combined with Figure 5 ), the second pressing block 721 is plugged into the second groove 722; the shapes of the second pressing block 721 and the second groove 722 are both adapted to the shape of the second separation groove 105. The formation of these two separation grooves not only facilitates the separation of two adjacent metal terminals 1, but also provides the necessary structural basis for subsequent cylinder forming.

[0067] Reference Figure 1 and Figure 5 After the separation groove is formed, the bending mechanism 8 starts to bend the edge of the metal terminal 1. The bending mechanism 8 includes an angle bending component 81 and a rounded corner bending component 82. The angle bending component 81 is used to bend the edge of the flat metal terminal 1, thereby processing a bending portion on the edge of the metal terminal 1, and the bending portion and the metal terminal 1 are not in the same plane. The rounded corner bending component 82 is used to process the bending portion from a flat shape to an arc shape. They cooperate with each other when the metal terminal 1 molding mold is closed to bend the edge of the metal terminal 1 into a preset angle.

[0068] Reference Fig.14 and Fig.15 The angle bending assembly 81 includes a first bending block 811 and a second bending block 812. The first bending block 811 is fixed to the fixed mold 2, and the second bending block 812 is fixed to the movable mold 3. When the metal terminal 1 forming mold is closed, the second bending block 812 is driven to move toward the direction close to the first bending block 811, thereby bending the edge of the metal terminal 1. The angle bending assembly 81 can achieve accurate bending of the edge of the metal terminal 1 when the metal terminal 1 forming mold is closed through the cooperation of the first bending block 811 and the second bending block 812, thereby improving the metal terminal 1 (combined with Figure 1 and Figure 2 ) molding accuracy and stability.

Through the cooperation of the first molding block 821 and the second molding block 822, the fillet bending assembly 82 can realize the processing of the bending part of the metal terminal 1 into an arc shape when the metal terminal 1 molding mold is closed, thereby improving the appearance quality and feel of the metal terminal 1.

[0071] Reference Figure 3 and Figure 5The fixed mold 2 is also provided with an inner support mechanism 11, which is used to support the inner wall of the metal terminal 1 when the cylinder forming mechanism 9 processes the metal terminal 1 into a cylinder. The setting of the inner support mechanism 11 effectively supports the inner wall of the metal terminal 1 during the cylinder forming process, prevents deformation and collapse during the forming process, ensures the integrity and firmness of the cylindrical structure, and improves the overall performance and reliability of the metal terminal 1.

[0072] Reference Fig. 20 The inner support mechanism 11 includes an inner support rod 111 and a sliding drive 112. The sliding drive 112 is arranged on the fixed mold 2.

Specifically, the sliding drive 112 can be a cylinder, which is fixed on the fixed mold 2, and the piston rod of the cylinder is fixedly connected to the inner support rod 111. The inner support mechanism 11 adopts the design of the inner support rod 111 and the sliding drive 112 to achieve precise control and flexible adjustment of the inner wall of the metal terminal 1. When the material strip channel is feeding, the inner support rod 111 is moved to the outside of the material strip channel by the driving member, thereby increasing the smoothness of the material strip channel feeding; when the cylinder forming mechanism 9 is forming the cylindrical metal terminal 1, the inner support rod 111 is driven by the sliding drive 112 to move to the inside of the metal terminal 1, thereby preventing deformation and collapse during the forming process, and ensuring the integrity and firmness of the cylindrical structure.

[0073] Continue to refer to Fig. 20 The inner support rod 111 is cylindrical, and the diameter of the outer wall of the inner support rod 111 is the same as the diameter of the inner wall of the metal terminal 1.

The slide cooperation of the guide block 113 fixedly provided on the inner support rod 111 and the second guide groove 22 on the fixed mold 2 provides stable guidance and limit for the movement of the inner support rod 111, ensures the accuracy and reliability of the inner support action, simplifies the structure of the molding mold, and facilitates maintenance and operation.

[0075] Continue to refer to Fig. 20The torsion mechanism 12 includes a support 121, a telescopic torsion rod 122, a first rotation driving member 123 and a telescopic driving member 124.

The first rotation driving member 123 is used to drive the telescopic torsion rod 122 to rotate. The specific telescopic driving member 124 can be a cylinder. The cylinder can be fixed on the support 121 or on the fixed mold 2. The piston rod of the cylinder is fixedly connected to the end of the telescopic torsion rod 122 through a connecting block. The specific first rotation driving member 123 can be a motor. The motor can be set on the support 121, and the motor is used to drive the telescopic torsion rod 122 to rotate. The design of the torsion mechanism 12, especially the rotational connection and sliding cooperation between the telescopic torsion rod 122 and the support 121, and the coordinated action of the telescopic drive member 124 and the first rotating drive member 123, makes the torsion forming process of the cylindrical metal terminal 1 more stable and controllable, and effectively solves the problem of the difficulty in processing the inclined grid groove 103.

[0076] Continue to refer to Fig. 20 The telescopic torsion rod 122 is provided with a guide column 125, the diameter of the guide column 125 is larger than the diameter of the telescopic torsion rod 122, the fixed mold 2 is provided with a first guide groove 21, the first guide groove 21 extends in the horizontal direction, the guide column 125 is slidably matched with the first guide groove 21, and the guide column 125 is rotatably connected with the first guide groove 21. The slidably matched and rotatably connected guide column 125 provided on the telescopic torsion rod 122 and the first guide groove 21 on the fixed mold 2 provide stable guidance and support for the torsion process, ensure the accuracy and consistency of the torsion, and further improve the precision and quality of the metal terminal 1.

[0077] Continue to refer to Fig. 20 The first guide groove 21 is an arc groove, and the first guide groove 21 extends in the horizontal direction, and the outer side wall of the guide column 125 abuts against the inner side wall of the first guide groove 21. The first guide groove 21 is designed as an arc groove, which is closely abutted against the outer side wall of the guide column 125, which not only optimizes the mechanical distribution during the torsion process, but also reduces friction and wear, prolongs the service life of the molding die, and reduces maintenance costs.

[0078] Reference Figure 3 After all the molding processes are completed, the finished metal terminal 1 is cut off by the cutting mechanism on the mold, and the finished metal terminal 1 falls into the receiving mechanism 16 for collection under its own gravity. The design of the receiving mechanism 16 fully considers the protection and sorting needs of the product to ensure safety and neatness during the collection process.

[0079] Continue to refer to Figure 3 The waste collection mechanism includes a support seat 171, a winding tray 172 and a second rotating drive member 173. A cavity is provided inside the support seat 171. The winding tray 172 is rotatably disposed in the cavity. The winding tray 172 is used to wind up the waste. The second rotating drive member 173 is disposed on the support seat 171. The second rotating drive member 173 is used to drive the winding tray 172 to rotate. The second rotating drive member 173 here can be a motor or a motor gear structure. When the winding tray 172 is driven to rotate by the second rotating drive member 173, not only can the waste be wound around the winding tray 172, but also the material belt can be driven to advance in the feeding channel, thereby improving the processing efficiency of the metal terminal 1.

[0080] The implementation principle of the above embodiment is as follows: This embodiment realizes the complete production process of the metal terminal 1 from raw materials to finished products through a series of automated processes such as feeding, forming, collecting and waste treatment. The precise coordination and highly automated control of each forming mechanism during the production process not only improves production efficiency, but also ensures the consistency and stability of product quality. This production method effectively solves the problems of the difficulty of forming the metal terminal 1 and the difficulty of precision control in the prior art, and provides an efficient and stable metal terminal 1 production solution for the field of electronic component and electrical parts manufacturing.

[0081] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
