Description

[Detailed description of the invention] The present invention relates to an improved structure of a crimp terminal processing machine, and more specifically, it is capable of accurately pitch-feeding crimp terminals, and pitch-feeding is possible when the size of crimp terminals changes, etc. The object of the present invention is to provide a crimp terminal processing machine that can shorten the time required for attaching and detaching mechanisms and can improve productivity.

Continuous terminal 1 consisting of crimp terminal units connected by a patch piece
A small manual processing machine for cutting wires into crimp terminal units and simultaneously crimp-connecting the ends of electric wires and the crimp terminal units has a structure as shown in FIG.

In this processing machine, a continuous terminal 11 placed on a surface plate 2 facing the terminal processing section 1 is moved upward and downward and reciprocated in pitch as a downward force is applied in the direction in which it comes into contact with the surface plate 2. The forward terminal processing section 1 is fed with a pitch of a predetermined length using the feed claw 4, and by operating the lever 6 behind the feed claw 4, the terminal can be kept parallel to the surface plate 2 and moved toward and away from it. The holding plate 5 and the surface plate 2 brake the continuous terminals 11 that have moved in pitch, and perform the crimping process for each crimp terminal.

The feed pawl 4 comes into contact with the rising part of the wire crimping part of the continuous terminal 11 at the fully retracted position, and moves forward to feed the continuous terminal 11 by the unit length of the crimp terminal, while the holding plate 5 When the processing unit 1 performs crimping connection with the electric wire and cutting the spliced piece at the same time using a press, the position of the continuous terminal 11 is fixed with an appropriate force in order to prevent the subsequent continuous terminal 11 from "shifting" or jumping up. It is something.

By the way, with such a structure, while the feed claw 4 is retracting from the fully advanced position, it comes into sliding contact with the surface of the terminal 11,
In addition, the movement of moving over the wire covering holding part and the wire crimping part causes vibration, which is not desirable, and causes problems such as damaging the continuous terminal, and furthermore, there is a situation in which the presser plate 5 lifts up during the shift. When this occurs, the feeding claw 4 moves the continuous terminal 11, causing a problem such as misalignment.

Furthermore, in order to adjust the movement angle of the pitch feed mechanism 7 or replace the feed pawl 4 at the start of work or when changing products, it is necessary to press the lever 6 down to release the continuous terminal 11, and then press the lever 6 down to release the continuous terminal 11. Another drawback was that the work could not be carried out quickly because it required an operation to raise the feed claw 4 which was in a stopped state.

In view of these various problems, the present invention makes it possible to eliminate the above-mentioned defects by making simple improvements to the conventional crimp terminal processing machine, thereby improving workability and production. This has led to the provision of a crimp terminal processing machine with a unique structure that can improve performance.

The processing machine of the present invention can achieve the intended purpose, especially based on a structure in which the feed claw 4 can be continuously stopped at the upper blade position of the surface plate 2 by separating the holding plate. The specific contents will be explained in detail below with reference to FIG.

The processing machine of the present invention has a pitch feeding mechanism 7 including a feeding claw 4 as an element, a crimping processing mechanism 8, and a terminal support mechanism consisting of a presser plate 5 and a lever 6 above a surface plate 2 facing the terminal processing section 1. Since the structure of each part is the same as that of the conventional machine shown in FIG. 1, the explanation will be omitted, and only the operating mode and the structure of the distinctive parts will be described.

By pushing down the crimping mechanism 8 in the direction of the arrow, the crimping section 1 performs crimping connection with the electric wire and cutting at the splicing piece at the same time. The swinging lever 9 swings counterclockwise from the illustrated position via an appropriate power transmission part, and the feed pawl 4 engaged with the swinging lever 9 is moved forward by a predetermined pitch while a downward force is applied. By this, continuous terminal 1 on surface plate 2
1 by a pitch corresponding to the unit length.

This pitch feeding operation is completed before the lower end of the crimping mechanism 8 reaches a predetermined position.

Further, when the crimping mechanism 8 returns to its original state, the power transmission is released and the elastic force of the spring 10 restores the pitch feeding mechanism 7 to its original state.

Therefore, in the present invention, the lever 6 for vertically moving the presser plate 5 is further extended from the engagement portion with the presser plate 5, and the tip of the extended portion 6a is connected to the arm-shaped base of the feed pawl 4. It is brought into contact with the lower surface of the part under a predetermined condition.

The above-mentioned predetermined state refers to, for example, a state in which the feed pawl 4 is at the fully retracted position and a position immediately before that, and the lever 6 is pressed down to a certain extent (the state shown in FIG. 2). Therefore, as the feed pawl 4 moves forward, the contact between the tip of the extension 6a and the arm-shaped portion is released as shown in FIG.

When the lever 6 having such a structure is pushed down, it lifts the holding plate 5 away from the surface plate 2, and at the same time restricts the feed pawl 4, which is in the retracted state, to the restraining position and moves it away from the surface plate 2. let

Therefore, when the work on the terminal processing section 1 is completed, if the lever 6 is pushed down at the same time as the restoration operation of the crimping processing mechanism 8 or one after another, the feed claw 4 can be moved to the wire sheath holding section of the continuous terminal 11 or the wire connection section. Since the return movement can be made without contacting the rising portion of the terminal, the continuous terminal 11 will not be displaced or damaged.

Then, when the lever 6 returns to its original position, it is sufficient to release the pressing operation of the lever 6, and this series of operations can be easily performed manually, or can also be automated mechanically.

Furthermore, when adjusting or replacing the pitch feed mechanism 7, the pitch feed mechanism 7 can be easily adjusted by operating the lever 6.
can be maintained in a free state unrelated to the surface plate 2, which greatly improves work efficiency.

As is clear from the above explanation, in the present invention, by simply operating the lever 6 for moving the terminal holding foot plate 5 toward and away from the surface plate 2, the foot plate 5 and the feed pawl 4 in the retracted position can be moved. Surface plate 2
Since the upper continuous terminal 11 is separated, replacement work and maintenance work can be performed quickly, and the operation for crimping the terminal and the operation of the lever 6 can be performed in time coordination. It also reliably prevents the feed pawl 4 from sliding against the terminal and damaging it or causing the terminal to become misaligned, and has a simple structure with various excellent effects.
This is an idea with a lot of practical value.
