Automatic wire installing-in device and method of metal braided wire terminal

Abstract

The invention discloses an automatic wire installing-in device and method of a metal braided wire terminal. The device comprises a forming mechanism, a terminal push mechanism, a clamping and moving mechanism and a controller. The forming mechanism comprises a forming mold, the forming mold comprises a fixed lower forming mold body and a movable upper forming mold body, when the upper forming mold body is pressed on the lower forming mold body, a first forming hole and a second forming hole are sequentially and coaxially formed in the forming mold, the diameter of the first forming hole is matched with the outer diameter of the terminal, and the second forming hole is matched with the diameter of a standard cylinder of a metal braided wire. The terminal push mechanism is arranged on the side, close to the first forming hole, of the forming mechanism, and is used for pushing the terminal into the first forming hole. The clamping and moving mechanism is arranged on the side, close to the second forming hole, of the forming mechanism, and is used for clamping the metal braided wire and reciprocating along the axis of the second forming hole. The device has the advantages of achieving full-automatic operation, and being low in production difficulty and high in production efficiency.

Description

technical field [0001] The invention relates to an automatic wire-entry device and method for a metal braided wire terminal. Background technique [0002] During the manufacturing process of metal braided wire, three processes are involved: wire cutting, wire feeding and terminal crimping. At present, these three processes are all done manually, but manual work is labor-intensive and low-efficiency. Among them, the wire cutting process and terminal crimping process can be processed with additional auxiliary tools. For example, scissors can be used to perform auxiliary operations when cutting wires, and pedal pneumatic crimping machines can be used to perform auxiliary operations when crimping terminals. The two processes The processing difficulty and strength are slightly lower than the purely manual line-in process. [0003] At present, the specific operation steps of the wiring process are as follows (taking the RNB14-5 terminal as an example): the crimping area of ​​the ...

AI Technical Summary

Problems solved by technology

[0003] At present, the specific operation steps of the wiring process are as follows (taking the RNB14-5 terminal as an example): the crimping area of ​​the RNB14-5 round bare terminal to be crimped is a round hole, and the flat metal braided wire must be pulled out from the The area within 18mm from the cutting end face is twisted into a cylinder so that the metal braided wire can be fed into the crimping hole of the terminal. Ideally, the diameter of the metal braided wire twisted into a cylinder is 4mm, and the crimping hole of the terminal The inner diameter is 5mm, and the metal braided wire should be just enough to be fed into the crimping hole, but it is difficult to obtain an ideal cylinder by manual twisting. Into the crimping hole, it is necessary to rotate the terminal while twisting the wire, and repeat it many times to put the metal braided wire into the crimping hole of the terminal

[0004] The above-mentioned threading process has the following problems: (1), the sharp core is easy to puncture fingers; (2), the twisted fingers are prone to pain and fatigue, and are not suitable for long-term work; (3), threading Difficult, need to repeatedly twist the wire and rotate the terminal, the efficiency is low; (4), there are flying wires after the wire is inserted, the end surface of the cut wire is not smooth, and it needs to be trimmed, which further wastes man-hours

[0005] To sum up, at present, in the production process of metal braided wire, there is no corresponding auxiliary tool or tooling for the wire entry process, and pure manual operation is adopted, which is difficult and inefficient.
