Description

Technical Field

[0001] This utility model relates to the field of terminal block stamping, and in particular to a terminal block stamping apparatus. Background Technology

[0002] Terminal blocks are accessories used to achieve electrical connections. They are a type of connector. When manufacturing terminal blocks using existing technology, it is usually necessary to punch copper, aluminum, copper alloys, or copper-aluminum alloys into conductive sheets of the required shape and size. It is also necessary to punch the connection position with the wire into a ring shape to facilitate the connection between the terminal block and the wire.

[0003] In the prior art, during the stamping process of terminal blocks, the metal tube is generally positioned by machining. After the machining is completed, the metal tube is processed into a terminal block by stamping. However, in the prior art, the positioning is done manually, and the terminal blocks are usually cut manually after machining. However, during the cutting process, some terminal blocks may be tightly connected to the positioning workpiece due to machining accuracy issues, which greatly reduces the cutting efficiency of the terminal blocks and is very inconvenient. Summary of the Invention

Each push rod extends out of the limiting hole under the drive of the drive rod and presses against the inner wall of the metal tube. Each drive plate has a rotating groove, and the extension direction of each rotating groove is parallel to the extension direction of the mounting rod. An elastic element is provided between the rotating groove and the stripping plate. One end of the stripping plate is rotatably connected in the rotating groove under the action of the elastic element, and the other end of the stripping plate presses against the metal tube. Each metal tube positioned and mounted on the mounting rod is moved to the underside of the stamping assembly by the drive cylinder driving the drive plate, and the stamping assembly stamps the metal tube to form a terminal block. The terminal blocks formed on each mounting rod are unloaded by the drive cylinder driving the drive plate, the reset of the mounting rod, and the pressing of the terminal blocks by each stripping plate.

[0006] Furthermore, each limiting hole has a side groove on its inner wall that is parallel to the axis of the limiting hole. The side of the push rod has a side slider that is adapted to each side groove. Each side slider is slidably disposed in the side groove. Each side groove has a tension spring. The two ends of the tension spring act on the side groove and the side slider, respectively. The push rod is slidably disposed in the limiting hole through the sliding cooperation of each side slider and the side groove, as well as the continuous force of the tension spring, and extends out of the limiting hole by the drive of the drive rod.

[0007] Furthermore, the aforementioned mounting rod is provided with a plurality of adjustment holes extending along the axial direction of the mounting rod, and the mounting rod is provided with adjustment pins that can adjust the length of the metal tube installation, the adjustment pins being inserted into the corresponding adjustment holes.

[0008] Furthermore, the aforementioned work platform is provided with a bottom slide groove arranged parallel to the axis of the mounting rod, and the bottom of the drive plate is provided with a bottom slider adapted to each bottom slide groove. The drive plate is slidably connected to the work platform by the drive of the drive cylinder and the cooperation of the bottom slider and the bottom slide groove.

[0009] Furthermore, the aforementioned rotating groove is provided with an inner rotating shaft, and the stripping plate is provided with an inner rotating hole adapted to the inner rotating shaft. The axes of the inner rotating shaft and the inner rotating hole are both set perpendicular to the working platform.

[0011] Furthermore, the stamping rod is provided with a connecting slot with an inverted trapezoidal cross section, and the stamping block is provided with a connecting plug that is adapted to each connecting slot. Each stamping block is installed on the stamping rod through the insertion and engagement of the connecting plug and the connecting slot and is fixed by a locking member.

[0012] This utility model has positive effects: (1) By setting a positioning component on the working platform, after each mounting rod extends into the metal tube, each top rod is driven by the first cylinder to position the driving rod, thereby pressing and positioning the inner wall of the metal tube. Then, the mounting rod is moved to the bottom of the stamping component for stamping by the driving cylinder to drive the driving plate. The stripping plate on each driving plate can limit and press the metal tube under the action of the torsion spring. In the process of resetting after the metal tube is processed into a terminal, each top rod returns to its original position. In the process of resetting the mounting rod, each anti-slip plate presses the terminal to unload the metal tube. This effectively solves the problem of excessive tight connection between the terminal and the mounting rod when manually unloading in the prior art, which affects the unloading efficiency. It greatly improves the unloading efficiency of the terminal. The structure is ingenious, convenient and practical.

[0013] (2) This utility model sets a side slide groove in the limiting hole and a tension spring in the side slide groove, thereby realizing the extension of the top rod under the drive of the drive rod and the automatic reset of the drive rod after reset. On the one hand, it can ensure the positioning of the metal tube, and on the other hand, it can also ensure the quick unloading of the wire terminal after processing and forming, which is efficient and convenient.

[0014] (3) This utility model sets multiple adjustment holes on the outer wall of the mounting rod, and limits the installation position of the metal tube by the cooperation of the adjustment holes and the adjustment pin. This further avoids the problem of the metal tube being installed too tightly with the mounting rod after stamping due to over-installation. This greatly ensures the accuracy of installation when the metal tube is fed and the efficiency of unloading.

[0015] (4) By setting a bottom slide groove on the working platform and a bottom slider on the drive plate, the drive plate is greatly guaranteed to be stable during the movement process by the drive cylinder and the cooperation of the bottom slide groove.

[0016] (5) This utility model sets a torsion spring on the rotating shaft, and the stripper plate is connected by the rotation of the inner rotating shaft and the inner rotating hole. The torsion spring continuously applies force to press against the metal tube. On the one hand, it can position and press the metal tube during installation. On the other hand, it can remove the connecting terminal from the mounting rod when pressing the terminal. It can also drop from the discharge slot into the material box to complete the discharge. It is convenient and practical.

[0017] (6) By setting up a stamping component, the stamping block and the punching block are driven by the stamping cylinder to stamp the metal tube. The stability of the stamping block and the punching block during the stamping process is ensured by the cooperation of the guide rod and the guide hole, which is efficient and convenient.

[0018] (7) This utility model provides a connecting slot on the stamping rod and a connecting plug on the stamping block. The cooperation between the connecting plug and the connecting slot effectively ensures the quick and efficient installation of the stamping block, making it convenient and practical.
