Description

Technical Field

[0001] This utility model relates to the field of terminal manufacturing technology, and in particular to a high-efficiency stamping die for producing multiple terminals in one go. Background Technology

[0002] In existing technologies, terminal forming requires the use of stamping dies. The stamping die presses a sheet of metal along its length to continuously stamp out semi-finished terminal products. Current stamping dies typically only produce four terminal products at a time. If the number of semi-finished terminal products needs to be increased, the spacing between adjacent terminals will be compressed. However, the width of the sheet metal is limited. When the spacing between adjacent terminals is too close, the impact force can easily deform them, thus reducing the yield rate. Utility Model Content

[0003] This invention provides a high-efficiency multi-terminal stamping die that can increase the number of terminals formed in a single stamping and ensure a high yield rate.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] This utility model provides a high-efficiency multi-terminal stamping die, including a base, a first stamping seat, a second stamping seat, a third stamping seat, a fourth stamping seat, and a fifth stamping seat. The first, second, third, fourth, and fifth stamping seats are all connected to the base. The first, second, third, fourth, and fifth stamping seats are sequentially distributed along a first direction. A first stamping groove is formed between the first and second stamping seats; two second stamping grooves are formed between the second and third stamping seats; two third stamping grooves are formed between the third and fourth stamping seats; and a fourth stamping groove is formed between the fourth and fifth stamping seats. The two second and two third stamping grooves are each distributed along a second direction. The first and second stamping grooves, the second and third stamping grooves, and the third and fourth stamping grooves are all staggered along the second direction. The first and second directions are perpendicular to each other.

[0006] In some embodiments, the first stamping seat has a first stamping portion protruding from the second stamping seat in a second direction, the second stamping seat has a second stamping portion protruding from the first stamping seat in a direction opposite to the second direction, the fifth stamping seat has a fifth stamping portion protruding from the fourth stamping seat in a second direction, and the fourth stamping seat has a fourth stamping portion protruding from the fifth stamping seat in a direction opposite to the second direction; when the base moves a predetermined distance from the first position to the second position in a direction opposite to the second direction, a fifth stamping groove is formed between the first stamping portion at the second position and the second stamping portion at the first position, and a sixth stamping groove is formed between the fifth stamping portion at the second position and the fourth stamping portion at the first position.

[0007] In some embodiments, the first stamping groove, the second stamping groove, the third stamping groove, the fourth stamping groove, the fifth stamping groove, and the sixth stamping groove each include a plug-in portion and a wiring portion.

[0008] In some embodiments, the lengths of the first stamping seat, the second stamping seat, the third stamping seat, the fourth stamping seat, and the fifth stamping seat are all equal in the second direction.

[0009] In some embodiments, the second stamping seat, the third stamping seat, and the fourth stamping seat are in the same position in the second direction.

[0010] In some embodiments, the base is provided with a notch located between the first stamping seat and the fifth stamping seat.

[0011] This invention has at least the following beneficial effects: A first stamping groove is formed between the first and second stamping seats; two second stamping grooves are formed between the second and third stamping seats; two third stamping grooves are formed between the third and fourth stamping seats; and a fourth stamping groove is formed between the fourth and fifth stamping seats. This results in six stamping grooves, allowing for the stamping of at least six terminals in a single operation, increasing the number of terminals formed in a single stamping operation. Simultaneously, the two second and two third stamping grooves are distributed along a second direction, and the first and second stamping grooves, the second and third stamping grooves, and the third and fourth stamping grooves are all staggered along the second direction. This effectively solves the problem of easily deformed stamped terminals caused by excessively close spacing between adjacent terminals, thereby ensuring a high yield rate.

[0019] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0020] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0022] The embodiments of this utility model provide a high-efficiency single-output multi-terminal stamping die, such as... Figure 1 and Figure 2As shown, it includes a base 100, a first stamping seat 210, a second stamping seat 220, a third stamping seat 230, a fourth stamping seat 240, and a fifth stamping seat 250. The first stamping seat 210, the second stamping seat 220, the third stamping seat 230, the fourth stamping seat 240, and the fifth stamping seat 250 are all connected to the base 100. Specifically, the first stamping seat 210, the second stamping seat 220, the third stamping seat 230, the fourth stamping seat 240, and the fifth stamping seat 250 can be fixedly connected to the base 100, or they can be integrally formed with the base 100.

[0023] The first stamping base 210, the second stamping base 220, the third stamping base 230, the fourth stamping base 240, and the fifth stamping base 250 are sequentially distributed along a first direction. A first stamping groove 310 is formed between the first stamping base 210 and the second stamping base 220; two second stamping grooves 320 are formed between the second stamping base 220 and the third stamping base 230; two third stamping grooves 330 are formed between the third stamping base 230 and the fourth stamping base 240; and a fourth stamping groove 340 is formed between the fourth stamping base 240 and the fifth stamping base 250. The shape and size of the first stamping groove 310, the second stamping groove 320, the third stamping groove 330, and the fourth stamping groove 340 are adapted to the terminal semi-finished product. After stamping, the excess part of the metal sheet is cut off by the stamping base, thereby forming the terminal semi-finished product. Thus, this embodiment has six stamping grooves, which can stamp at least six terminals at a time, increasing the number of terminals formed in a single stamping.

[0024] Two second stamping grooves 320 are distributed along the second direction, and two third stamping grooves 330 are also distributed along the second direction to reduce the space occupied in the first direction. The first stamping groove 310 is staggered with the second stamping groove 320 in the second direction, the second stamping groove 320 is staggered with the third stamping groove 330 in the second direction, and the third stamping groove 330 is staggered with the fourth stamping groove 340 in the second direction. The first and second directions are perpendicular to each other. This can increase the spacing between adjacent stamping grooves, avoid excessive stress concentration, and prevent the stamped terminals from deforming, thereby ensuring a high yield. At the same time, due to the staggered arrangement of the stamping grooves, the widest part of the stamping groove is not accumulated in the first direction, which provides a basis for forming a four-row distribution of stamping grooves.

[0025] It should be noted that the embodiment provided is the upper die part of the stamping die. The structure of the lower die part is adapted to the upper die part to cooperate in forming the terminal. This is common knowledge in the field, and the lower die part will not be described in detail.

[0026] In some embodiments, such as Figure 2 and Figure 3As shown, the first stamping seat 210 has a first stamping portion 211 that protrudes from the second stamping seat 220 in the second direction. The second stamping seat 220 has a second stamping portion 221 that protrudes from the first stamping seat 210 in the direction opposite to the second direction. The fifth stamping seat 250 has a fifth stamping portion 251 that protrudes from the fourth stamping seat 240 in the second direction. The fourth stamping seat 240 has a fourth stamping portion 241 that protrudes from the fifth stamping seat 250 in the direction opposite to the second direction. When the base 100 moves a preset distance from the first position in the direction opposite to the second direction to reach the second position, a fifth stamping groove 350 is formed between the first stamping portion 211 located at the second position and the second stamping portion 221 located at the first position, and a sixth stamping groove 360 is formed between the fifth stamping portion 251 located at the second position and the fourth stamping portion 241 located at the first position.

[0027] During actual production, since the metal sheet moves in the second direction, after the previous stamping is completed, when the metal sheet moves the above-mentioned preset distance in the second direction, it is equivalent to the base 100 moving a preset distance from the first position in the direction opposite to the second direction to reach the second position. The shapes and sizes of the fifth stamping groove 350 and the sixth stamping groove 360 are adapted to the terminal semi-finished product. After stamping, the excess part of the metal sheet is cut by the stamping seat, thereby forming the terminal semi-finished product. Thus, this embodiment has eight stamping grooves, can stamp out eight terminals, further increasing the number of terminals formed by stamping and increasing the output.

[0028] In this embodiment, the preset distance can be determined by those skilled in the art according to the actual situation. For example, it can be the distance of the length of one stamping seat.

[0029] In some embodiments, the first stamping groove 310, the second stamping groove 320, the third stamping groove 330, the fourth stamping groove 340, the fifth stamping groove 350 and the sixth stamping groove 360 all include a plug-in portion and a wiring portion. The plug-in portion forms the plug part of the terminal for plugging in electrical components such as inserts, and the wiring portion forms the wiring head of the terminal for connecting with a wire to conduct electric energy. In this embodiment, the plug-in portion can Figure 2 be the generally circular part of the stamping groove, and the wiring portion is Figure 2 the generally "T-shaped" part of the stamping groove.

[0030] In some embodiments, the lengths of the first stamping seat 210, the second stamping seat 220, the third stamping seat 230, the fourth stamping seat 240 and the fifth stamping seat 250 in the second direction are all equal. This can better control the positions of the fifth stamping groove 350 and the sixth stamping groove 360 and ensure the quality of the products formed by the fifth stamping groove 350 and the sixth stamping groove 360.

[0031] In some embodiments, the second stamping seat 220, the third stamping seat 230 and the fourth stamping seat 240 are in the same position in the second direction, and the adjacent stamping slots can be misaligned by utilizing the positional change of the stamping slots in the second direction.

[0032] In some embodiments, the base 100 is provided with a notch 110 located between the first stamping seat 210 and the fifth stamping seat 250. Since both the first stamping seat 210 and the fifth stamping seat 250 have portions protruding along the second direction, the presence of the notch 110 can reduce the material used in the base 100, thereby reducing the manufacturing cost of the entire stamping die.

[0033] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
