Description

Technical Field

[0001] This utility model relates to the field of terminal processing technology, specifically to a terminal stamping die punch. Background Technology

[0002] Terminals are metal parts used to fix wires or cables in electrical connections. They achieve reliable contact and conductivity of conductors through mechanical crimping, screw fastening, or elastic clamping. Current technology often uses stamping to produce terminals, and the structure of the punch has a significant impact on the structural forming of the terminal.

[0003] In the prior art, the punch used for terminal stamping dies lacks a reliable structural design and cannot effectively press out arc-shaped clips, which makes it inconvenient to clamp and fix the wire ends later. Moreover, during stamping, the localized stamping force can easily cause the terminals to lift up. In addition, since the terminal parts are small in size, it is necessary to ensure stamping accuracy during stamping. Therefore, we propose a terminal stamping die punch. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a terminal stamping die punch with a reliable punch mounting unit, facilitating punch installation and replacement. The rounded corner structure at the lower end of the punch cooperates with the die to stamp two upward-curved arc-shaped pieces from the metal terminal, forming a crimping part for the wire conductor. It also features a reliable punch guiding unit; the guide rod slides into the guide sleeve, improving the stability of the mounting base during lifting and ensuring the accuracy of the punch stamping process. Furthermore, the pressure block can simultaneously press the front part of the metal terminal while the punch presses out the arc-shaped pieces at the tail, preventing the front of the metal terminal from lifting during stamping. The cutting tool can cut individual metal terminals simultaneously during punching, thereby improving processing efficiency and effectively solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a terminal stamping die punch, comprising a fixing plate, a punch guide unit, and a punch mounting unit;

[0006] Fixed plate: A rectangular plate that is set horizontally;

[0007] Punch guide unit: mounted on the underside of the fixed plate;

[0008] Punch mounting unit: includes mounting slot, punch, locking block, bolt through slot and long bolt. The punch guide unit includes mounting base. The mounting base has a horizontally opened mounting slot inside. The vertical cross-section of the mounting slot is T-shaped, and a square locking block is slidably connected inside. The punch is fixedly connected to the lower side of the locking block and extends downward from the vertical section of the mounting slot. The horizontal edges on the front and rear sides of the lower end of the punch are all machined with rounded corners. The lower end of the mounting base is assumed to have two bolt through slots. Two long bolts are provided. The two long bolts pass through the two bolt through slots on the lower side and are threaded into the inside of the locking block.

[0009] The punch and the locking block are combined into a T-shaped structure. The punch can be hoisted by sliding the punch and the locking block into the mounting slot. The locking block can be fixed by inserting a long bolt from the bottom and can be easily disassembled to replace different punch components. The bolt through slot allows the bolt to be adjusted with the locking block, thus supporting lateral fine adjustment of the locking block's fixed position. The rounded corner structure at the lower end of the punch is used to press two upward-curved arc-shaped pieces of metal terminal with the mold. By placing the wire end between the two arc-shaped pieces and clamping it with pliers, the wire end can be fixedly connected to the metal terminal.

[0010] Furthermore, the punch guide unit includes a hydraulic cylinder, a mounting base, and bolt slots. The hydraulic cylinder is centrally mounted on the lower end of the fixing plate, with its extension end facing downwards and fixedly connected to the upper center of the mounting base. The mounting base is a cuboid structure. A quarter-circular bolt slot is provided at each of the four corners of the lower end of the fixing plate, and a bolt through hole is provided on the upper side of each bolt slot. The fixing plate is used for mounting the hydraulic cylinder. Bolts are installed in the bolt slots at the four corners of the fixing plate to secure it. The hydraulic cylinder drives the mounting base to rise and fall, thereby driving the punch below to perform the punching action.

[0011] Furthermore, the punch guide unit also includes guide sleeves, fixing blocks, and guide rods. A vertical guide sleeve is installed at each of the four corners of the upper end of the mounting base. An annular fixing block is fixedly connected to the lower end of each guide sleeve. The fixing block has four bolt through holes arranged in a circular array inside, each containing an internal hexagonal bolt. The fixing block is fixedly connected to the mounting base via these bolts. Four guide rods are fixedly connected to the lower end of the fixing plate, and each guide rod is inserted into one of the four lower guide sleeves. By adding bolts inside the fixing block, the fixing block and the upper guide sleeves can be fixed. The guide rods slide into the guide sleeves, thereby improving the stability of the mounting base during lifting and lowering, and ensuring the accuracy of the punch during stamping.

[0012] Furthermore, the punch mounting unit also includes a pressure block. A transverse section of the pressure block is fixedly connected to the lower right side of the punch, and the lower end of the pressure block is horizontal with the lower end of the punch. The pressure block is used to press the front part of the metal terminal while the punch presses out the arc-shaped tail piece of the metal terminal, preventing the front part of the metal terminal from lifting up during punching.

[0013] Furthermore, the punch mounting unit also includes a cutting tool. The cutting tool is fixedly connected to the lower left side of the punch. The lower end of the cutting tool has an arc-shaped structure and extends slightly beyond the rounded corner structure at the lower end of the punch. The cutting tool can simultaneously cut individual metal terminals during punching, thereby improving processing efficiency.

[0014] Furthermore, the punch guide unit also includes an oil injection groove, and an annular oil injection groove is provided on the upper end of the guide sleeve, near the guide rod. The oil injection groove is used for adding lubricating oil, thereby achieving a self-lubricating effect while the guide rod and guide sleeve slide together.

The punch 32 is fixedly connected to the lower side of the locking block 33 and extends downward from the vertical section of the mounting slot 31. The horizontal edges on the front and rear sides of the lower end of the punch 32 are all machined with rounded corners. The lower end of the mounting base 22 is assumed to have two bolt through slots 34 at the front and rear. Two long bolts 35 are provided. The two long bolts 35 pass through the interior of the two lower bolt through slots 34 respectively and are threaded into the interior of the locking block 33.

[0029] The punch 32 and the locking block 33 are combined into a T-shaped structure. By sliding the punch 32 and the locking block 33 into the mounting slot 31, the punch 32 can be hoisted. The locking block 33 can be fixed by inserting a long bolt 35 from the bottom and can be easily disassembled to replace different punch 32 components. The bolt through slot 34 allows the bolt to be adjusted with the locking block 33, thereby supporting the lateral fine adjustment of the fixed position of the locking block 33. The rounded corner structure at the lower end of the punch 32 is used to cooperate with the mold to punch two upward-curved arc-shaped pieces of metal terminals. By placing the wire end between the two arc-shaped pieces and clamping it with pliers, the wire end and the metal terminal can be fixedly connected.

[0030] The punch guide unit 2 includes a hydraulic cylinder 21, a mounting base 22, and bolt slots 27. The hydraulic cylinder 21 is centrally mounted on the lower end of the fixing plate 1, with its extension end facing downwards and fixedly connected to the upper center of the mounting base 22. The mounting base 22 is a cuboid structure. A quarter-circular bolt slot 27 is provided at each of the four corners of the lower end of the fixing plate 1, and a bolt through hole is provided on the upper side of each bolt slot 27.
