DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal processing for forming a terminal by forming a continuous wire at predetermined intervals and cutting the wire, and press-fitting the terminal into an object to be pressed.
The present invention relates to a press-fitting device.

[0002]

2. Description of the Related Art A conventional terminal processing / press-fitting device of this type will be described with reference to the drawings.

FIG. 3 is a front view showing the structure of a conventional terminal processing / press-fitting device, and FIG. 4 is an enlarged view of a main part of the device.

In the conventional apparatus, as shown in FIGS. 3 and 4, the wire 1 is unwound from the wire reels 2 as many as the number of terminals 35 to be press-fitted into the press-fitted object 34, and the strainer 1 is wound.
After the wire 1 is passed through and the forming process is performed by the forming mechanism 36 having the forming punch 20, the wire 1 is pressed into the press-fitted object 34 by the press-fitting mechanism 37 while the wire 1 is held by the forming punch 21, and the bushing mechanism 38 Then, the wire 1 protruding from the press-fitted object 34 is cut by the cutting mechanism 39 provided with the cutter 25 to form the terminal 35.

[0005]

However, the conventional terminal processing and press-fitting device requires the same number of wire reels 2 and strainers 11 as the number of terminals 35 to be press-fitted.
For this reason, there has been a problem that it takes time to switch types, or that there are many management items for equipment operation and product defects.

Further, since the number of forming punches 21 required is equal to the number of the terminals 35 to be press-fitted, variations in the shape of the forming are generated, and there are problems such as cutting mistakes or cracking of the press-fitted object 34 at the time of press-fitting. There was a problem that the operation rate of the equipment and the non-defective product rate were reduced.

The wire 1 is fed downward while holding the wire by a forming punch 21 which is formed into a wedge-shaped or flat shape to increase the pull-out strength after press-fitting, and is released downward. There is a problem that it takes too much time to perform the operation of returning to the upper side, and the equipment tact becomes longer.

Further, since the wire 1 is held by the forming punch 21, if the position of the press-fitting hole between the wire 1 and the press-fitted object 34 at the time of press-fitting is shifted, the press-fitted object 34 is broken.

An object of the present invention is to provide a terminal processing / press-fitting device which can solve the above-mentioned conventional problems and can improve productivity and reliability with a simple configuration.

[0010]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a terminal processing / press-fitting device according to the present invention comprises a supply section for supplying a wire wound on a reel, and a wire for correcting the wire supplied from the supply section. A first transport unit having a straightening mechanism for performing the forming process, a forming unit configured to perform a forming process at a desired position of a wire disposed and supplied on an extension of the path of the first transport unit, and a forming unit configured to perform the forming process. The formed wire sent through the second transfer unit for transferring the formed wire is cut and separated into desired dimensions to obtain terminals, and a plurality of holding holes for individually holding the obtained terminals. A structure comprising a cutting portion provided and a terminal press-fitting portion which is provided via a terminal conveying pipe connected to a lower end of the cutting portion and press-fits a plurality of terminals held by the cutting portion into an object to be press-fitted at the same time. age It is intended.

[0011]

With this configuration, it is possible to use a single wire for processing a plurality of terminals, and by using one wire reel, the wire can be exchanged in a short time.
Equipment stoppage due to unwinding and correction of wires, reduction in factors of product failure, and reduction in management points can be achieved.

Further, the forming part and the cutting part have one
Because of the location, variations in the forming shape and the cut portion do not occur, cutting errors or problems such as cracking of the press-fitted object at the time of press-fitting do not occur. Yes, the number of management points can be reduced.

[0013] In addition, the feed operation can be stopped at an arbitrary position by adopting a configuration in which the feed of the wire is performed by the second transport unit at the same time as the forming, cutting, and press-fitting operations. Can be shortened.

Further, the terminal is free, although there is a certain restriction in the radial direction at the time of press-fitting, and the end face is conical or pyramid-shaped, so that the terminal extends along the press-fitting hole of the object to be press-fitted. Since the press-fitting is performed close to the center, no crack occurs in the press-fitted object.
