[0002] Terminal block manufacturing equipment refers to specialized equipment or production lines used to produce electrical connection components called "terminal blocks". Its core function is to process metal strips (such as copper and aluminum) into terminal bases through processes such as stamping and cutting.

[0003] As a key component for electrical connections, the manufacturing efficiency and precision of terminal blocks directly affect the reliability of electrical equipment. Traditional manufacturing equipment generally adopts a single-station segmented production mode, which results in low efficiency due to the dispersion of processes. Specifically, existing equipment often requires the transfer of workpieces between different devices, which is time-consuming and causes cumulative errors due to multiple positioning. Therefore, we propose a manufacturing device for terminal blocks. Utility Model Content

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1-5 A manufacturing apparatus for terminal blocks is provided. The manufacturing apparatus for terminal blocks includes a frame 1. The top of the frame 1 has an integrally formed limiting cylinder 101. The bottom wall of the inner cavity of the limiting cylinder 101 is provided with a coaxial arc-shaped limiting plate 102. A limiting ring 103 is installed on the inner cavity wall of the limiting cylinder 101.

[0028] The rotary worktable 2 is rotatably installed inside the limiting cylinder 101. The top of the rotary worktable 2 has at least 6 sets of mold mounting positions 201 evenly distributed in the circumference. Each position corresponds to the feeding, stamping, injection molding, cooling, inspection and unloading processes in sequence. Each set of mold mounting positions 201 has a fixing hole 202.

[0029] The drive mechanism includes a servo motor 301 mounted on the bottom of the limit cylinder 101 and a drive shaft 302 vertically mounted on the bottom of the rotary table 2. The output shaft of the servo motor 301 is connected to the end of the drive shaft 302 away from the rotary table 2.

[0030] The PLC controller 4 is mounted on the frame 1. The PLC controller 4 is electrically connected to the servo motor 301 and controls the rotary table 2 to rotate in 60-degree intervals. In the application, by adopting the indexing design of the rotary table 2, the 6 sets of mold mounting positions 201 can realize the integration of multiple processes, reduce the number of workpiece transfers, and improve production efficiency. At the same time, the PLC controller 4 provides precise control to ensure the accuracy of rotation positioning and eliminate the cumulative error of traditional manual operation.

[0031] Reference Figures 2-5 The bottom of the rotary worktable 2 is provided with a bottom limiting groove 203 corresponding to the arc-shaped limiting plate 102, and the bottom limiting groove 203 is adapted to the arc-shaped limiting plate 102. The rotary worktable 2 is rotatably installed in the limiting cylinder 101 through the bottom limiting groove 203 and the arc-shaped limiting plate 102. In application, the arc-shaped limiting plate 102 and the bottom limiting groove 203 form an axial constraint, which can reduce the vibration amplitude of the rotary worktable 2 and extend the service life of the equipment.

[0032] Reference Figures 2-5 The outer surface of the rotary worktable 2 is provided with a side limiting groove 204 corresponding to the limiting ring 103, and the side limiting groove 204 is adapted to the limiting ring 103. The rotary worktable 2 is rotatably installed in the limiting cylinder 101 through the side limiting groove 204 and the limiting ring 103. The limiting ring 103 is located in the upper middle part of the height direction of the limiting cylinder 101. In application, the limiting ring 103 and the side limiting groove 204 provide radial support, which can reduce the vibration amplitude of the rotary worktable 2 and extend the service life of the equipment.

[0033] Reference Figure 2 and Figure 5 The surface of the drive shaft 302 is provided with a polytetrafluoroethylene (PTFE) wear-resistant coating with a thickness of 50-80 μm. In application, the PTFE coating can reduce the friction coefficient of the drive shaft 302 and reduce energy consumption, so as to avoid metal wear debris contaminating the terminals.

[0034] Reference Figure 1 , Figure 2 as well as Figure 5 The rotary worktable 2 is made of 40CrMnMo (high-strength medium-carbon quenched and tempered manganese steel) alloy steel, and the surface hardness of the rotary worktable 2 is ≥HRC50. In application, the 40CrMnMo material can resist stamping deformation and extend the service life of the mold mounting position 201.

[0035] The working principle of this utility model is as follows: The PLC controller 4 sends a pulse signal of rotation command to the servo motor 301. At this time, the output shaft of the servo motor 301 drives the drive shaft 302 to rotate. The drive shaft 302 drives the rotary table 2 to rotate until the mold mounting position 201 is rotated to the initial processing position. During this period, the arc-shaped limiting plate 102 and the bottom limiting groove 203 form axial constraints, and the limiting ring 103 and the side limiting groove 204 provide radial support to form axial and radial double constraints. At the same time, the polytetrafluoroethylene coating on the drive shaft 302 reduces shaft friction vibration. The above steps complete one rotation of the workstation to complete the manufacturing of the terminal block. This enables multi-process integration, reduces the number of workpiece transfers, and improves production efficiency. At the same time, the PLC controller 4 provides precise control and can eliminate the cumulative errors of traditional manual operation.

[0036] This utility model provides a manufacturing device for terminal blocks. The device adopts a rotary worktable with indexing design and six sets of mold mounting positions 201 to achieve multi-process integration, reduce the number of workpiece transfers, and improve production efficiency. At the same time, the PLC controller 4 provides precise control to ensure the accuracy of rotation positioning and eliminate the cumulative error of traditional manual operation.
