Specifically, the base 11 receives the terminal 40 in the first state 41 thereon, and the second shaped wall 211 of the pushing structure 21 pushes the terminal 40 to the first shaped wall 121 and presses the terminal 40 to the second state 42. It can be understood that the base 11 and the sizing seat 12 can be arranged at intervals, and a small gap is left between the base and the sizing seat; in the process that the pushing and driving structure 22 drives the pushing and driving structure 21 to push the terminal 40 toward the first shaped wall 121, due to the fast speed and the short stroke, the terminal 40 can be pressed between the second shaped wall 211 and the first shaped wall 121 without slipping out from the gap between the base 11 and the shaped seat 12, and further pushed to a predetermined arc.

In conclusion, the present application solves the technical problem of how to rapidly form the terminal 40.

Referring to fig. 1, fig. 2 and fig. 5, alternatively, in the present embodiment, the first shaped wall 121 is a convex arc surface, and the second shaped wall 211 is a concave arc surface; alternatively, the first shaped wall 121 is a concave arc surface, and the second shaped wall 211 is a convex arc surface. Wherein, the convex cambered surface means that the curvature center is positioned on a corresponding structure; concave arc means that the center of curvature is located outside the corresponding structure. It is understood that, in the present embodiment, the first and second shaped walls 121 and 211 are moved toward each other on both sides of the terminal 40, respectively, thereby pressing both sides of the terminal 40, respectively; one side surface of the terminal 40 is protruded outward and the other side surface is depressed inward and bent as a whole into a predetermined shape having a predetermined curvature.

Referring to fig. 1, fig. 2 and fig. 5, optionally, in the present embodiment, a first material guiding channel 131 is disposed on the base 11; the first guide passage 131 may be formed by a groove penetrating horizontally through the base 11, or may be formed by providing a protrusion extending horizontally on the base 11. A feeding port 1311 for receiving the terminal 40 and a discharging port 1312 for abutting against the first shaping wall 121 are formed at both ends of the first material guiding channel 131; the terminal 40 enters the first material guiding channel 131 through the material inlet 1311 and exits the first material guiding channel 131 through the material outlet 1312. The first material guiding channel 131 is arranged along the sliding track of the pushing structure 21 to guide and limit the sliding of the pushing structure 21.

It can be understood that, referring to fig. 3, the material inlet 1311 is used for receiving the terminal 40 in the first state 41 after being processed by the previous process; at this time, the pushing structure 21 located here abuts against the terminal 40, and the terminal 40 is pushed into the first material guiding channel 131 under the driving of the pushing driving mechanism; thereafter, referring to fig. 4, the pushing structure 21 continues to slide along the first material guiding channel 131 under the driving of the pushing driving structure 22, so as to push the terminal 40 out through the discharge hole 1312 and abut against the first shaped wall 121 located therein, thereby clamping the terminal 40 between the first shaped wall 121 and the pushing structure 21. The mutually adapted biasing structure 21 and the first shaped wall 121 press the terminal 40 from both sides, respectively, so that the terminal 40 is deformed into the second state 42 exhibiting a predetermined curvature. It can be understood that the first material guiding channel 131 has a limiting effect on the conveying path of the terminal 40, and can prevent the terminal 40 from generating a horizontal position deviation in the pushing process by the pushing structure 21, and further accurately convey to the first shaping wall 121 and be squeezed into the second state 42.

In addition, the pushing structure 21 abuts against the terminal 40 at the feeding port 1311, and the ends of the two stopping structures 13 at the feeding port 1311 abut against the two ends of the terminal 40 from the opposite direction to the pushing structure 21, so that when the terminal 40 is pushed by the pushing structure 21 towards the first shaping wall 121, the two stopping structures 13 also bear resistance forces in the opposite directions applied from the two ends of the terminal 40, so that the two ends of the terminal 40 are bent and can be attached to the corresponding end surfaces of the pushing structure 21, so as to preliminarily shape the terminal 40; during the process of transferring, the preliminarily formed terminals 40 are continuously limited by the stop structures 13 located at the two sides, and can continuously attach to the surface of the pushing structure 21 to move, and finally are extruded and shaped at the first shaping wall 121.

Referring to fig. 2 to 4, alternatively, the two stopping structures 13 are cylindrical structures, and the opposite surfaces of the two stopping structures 13 are disposed in parallel, so that the widths of the first material guiding channel 131 along the conveying direction are the same.

It can be understood that when the terminal 40 is received, the contact point of the pushing structure 21 and the terminal 40 is disposed at the middle part of the terminal 40, which helps to make the two ends of the terminal 40 uniformly receive the resistance of the two stopping structures 13, and further, the two ends are uniformly attached to the corresponding end surfaces of the pushing structure 21 from the two sides.

Optionally, the two stoppers 13 are formed with an inclined surface at the material inlet 1311 for the terminal 40 to slide into, that is, the sectional area of the material inlet 1311 gradually decreases along the direction from the material inlet 1311 to the material outlet 1312. It can be understood that the inclined surfaces help to smoothly slide both ends of the terminal 40 into the first guide passage 131 and can provide a buffering action for the terminal 40 so that the terminal 40 can be gradually applied to the corresponding end surfaces of the push structure 21.

Referring to fig. 1 to fig. 3, optionally, in the present embodiment, the two stopping structures 13 are formed with arc-shaped wall surfaces at the material inlet 1311 for the terminal 40 to slide into; that is, the sectional area of the material inlet 1311 is gradually reduced along the direction from the material inlet 1311 to the material outlet 1312, and the corresponding end of any stopper 13 is formed into a convex curved surface. It can be understood that the curved surface helps to make both ends of the terminal 40 smoothly slide into the first material guiding channel 131, and can provide a buffering action for the terminal 40 so that the terminal 40 can gradually adhere to the corresponding end surface of the pressing structure 21; and the curved surface at the feeding hole 1311 is in smooth transition with the inner wall of the first material guiding channel 131, so that damage caused by second rubbing during pushing and pressing of the terminal 40 can be effectively avoided.

It is understood that the limiting groove 141 can further limit the moving track of the terminal 40 for the terminal 40, so that the terminal 40 can be accurately transferred to the first forming wall 121 through the base 11 and pressed to a predetermined curvature. It is understood that the limiting groove 141 can be directly opened at a corresponding position of the base 11 and extend along the conveying direction of the terminal 40; two convex structures may be disposed on the base 11 at intervals to form the limiting groove 141.

Referring to fig. 3 and fig. 5, optionally, in the present embodiment, two spacing structures 14 are protruded from the bottom of the first material guiding channel 131, and the spacing groove 141 is formed between the two spacing structures 14. It is understood that the two position-limiting structures 14 may be column-shaped structures, and the two position-limiting structures 14 are spaced and arranged in parallel to form the position-limiting grooves 141 with the same width throughout.

Referring to fig. 2, fig. 4 and fig. 5, optionally, in the present embodiment, an end surface of the base 11 facing the first shaped wall 121 is a curved surface adapted to the first shaped wall 121. It can be understood that, the end surface of the base 11 facing the first shaped wall 121 is configured to be a curved surface matching the first shaped wall 121, which helps to reduce the gap therebetween, so as to effectively prevent the terminal 40 from slipping out of the gap between the base 11 and the shaped seat 12 without being press-shaped.

Referring to fig. 2, 4 and 5, it is understood that the terminal 40 can be separated from the pushing structure 21 and press-fitted to the stator 50 from the discharge hole 1312 after being pressed to the predetermined arc of the second state 42; the terminal 40 that is disengaged from the biasing structure 21 is not subjected to the pressing action between the biasing structure 21 and the first shaped wall 121, and thus easily bounces back to be difficult to maintain in the second state 42. The end of the base 11 facing the shaped seat 12 is curved to fit the first shaped wall 121, which helps to provide a guide and a stop for the press-fitting of the terminal 40, and helps to prevent the terminal 40 from bouncing after it has been detached from the pushing structure 21 and to keep the sheet in the second state 42 in which it is arranged in a predetermined arc.
