Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a wire end treatment method in which a wire is cut and then the coated portion of the end of the cut wire is stripped by a predetermined strinoprop length.

[Prior Art] Conventionally, as a device for automatically performing such terminal processing, a cutter blade and a strip blade are attached to fixed positions of two sets of blade bodies located across the wire feed line. There is a composition. In the case of this device, the cutting of the wire and the stripping of the coating are performed by a combination of a fixed amount of approaching and separating movements of two sets of blade bodies, a clamping action of the wire by the clamper, and a fixed amount of pulling action of the wire by the clamper. It is supposed to be done.

That is, first, a wire is fed between two sets of blade bodies, and then the wire is clamped by a clamper.
After that, the two sets of plate bodies are brought close to each other by a certain amount,
The wire rod is cut using the canoter blades of SoiN et al., and these strip blades are used to cut into the coating. Then, with the Strinop blade cut into the coating, a certain amount of wire is pulled with the clamper,
Strethop the covering.

In this type of device, a canoter blade and a strip blade are attached to fixed positions on the blade body, and the spacing between them is fixed, so the strip length of the coating section is adjusted depending on the spacing. will inevitably be determined. Further, since the two sets of blade bodies are close to each other by a certain amount, the depth of cut into the covering portion is inevitably determined depending on the length of the strip blade.

Incidentally, the wire rods handled by such an apparatus vary in thickness and strip length of the covering portion, and it is required to accommodate these.

[Problems to be Solved by the Invention] However, in the processing method using the above-mentioned apparatus, the strip length is determined by the attachment interval between the canotar blade and the strip blade, and the strip length is determined by the length of the strinop blade. Since the cutting depth of the cover is determined, when processing wire rods with different thicknesses and lengths, the blade body must be replaced with a different one41, and the replacement work is extremely time-consuming. This is troublesome and requires the hassle of preparing and managing various blade bodies.

This invention aims to solve such problems.

[Means for Solving the Problems] The wire rod end treatment method of the present invention includes: cutting the wire rod and then stripping the coated portion of the cut end of the wire rod by a predetermined strip length. In this method, two sets of blade bodies to which a relatively long cutter blade and a relatively short strip blade are attached are placed opposite to each other across the wire feed line, and the cutter blade and the strip blade are connected along the wire feed line with the strip blade in between. is equipped with a clamper that clamps the wire at the opposite position, feeds the wire between the two sets of blade bodies, clamps the wire with the clamper, and then
The wire rod is cut between the blade bodies of the set by a predetermined distance, and the wire rod is cut between the canoter blades attached to them, and then the clamper that has clamped the wire rod is used to cut the wire rod by a distance S corresponding to the strip length of the covering section. Slide it along the feed line, then bring the two sets of blade bodies closer together by a distance corresponding to the thickness of the wire, and let the strip blades attached to them cut into the sheathing of the wire, and then remove the strip. The method is characterized in that the clamper that has clamped the wire is further slid along the feeding line of the wire while the blade cuts into the sheath of the wire, thereby stripping the sheath of the wire.

[Function] The wire rod end treatment method of the present invention processes the wire rod ends by combining two-step approaching movement of the blade body, a clamping operation of the clamper, and a two-step sliding operation of the clamper. By controlling the amount of these movements, it is possible to arbitrarily set the amount of cut into the wire sheathing and the strip length of the sheath, making it possible to process wires with various thicknesses, slip lengths, and slip lengths. do.

[Example 1 Hereinafter, one embodiment of the present invention will be described based on the drawings.

First, a wire end processing apparatus that implements the method of this embodiment will be briefly described.

In the figure, reference numeral 1.2 denotes a pair of upper and lower blade bodies, which face each other across the feed line of the wire W, and are moved toward and away from each other by a servo motor (not shown). A relatively long cassotater plate 3 and relatively short left and right strip plates 4, 5 are attached to fixed positions facing each other in the blade body 1.2. Furthermore, clampers 67 for clamping the wire W are arranged on the left and right sides of the blade main body 1.2 and on the left and right sides of the feed line of the wire W. These clampers 6, 7 are configured to clamp the wire W between upper clamp members 6a, 7a and lower clamp members 6b, 7b. The clamper 67 also includes a servo motor (not shown) that moves the former members 6a, 72L and the latter members 6b7b closer to each other and away from each other, and a servo motor (not shown) that moves the clamper 6.7 closer to each other and closer to each other.
A servo motor (not shown) is provided that slides the wires in the direction of separation, that is, in the direction along the feed line of the wire W.

Next, a method for processing the ends of the wire W carried out by such an apparatus will be described.

First, as shown in Figure 1(a), the upper and lower blade bodies 1.2
, and open the clamper 6.7 to feed the wire W from the right to the left in the figure. After feeding the wire W for a predetermined length, the clamper 6.7 is closed to clamp the wire W, as shown by the two-dot chain line in FIG.

After that, as shown in the same figure (b), the upper and lower blade bodies 1.2
are moved close to each other by a predetermined distance, and the wire rod W is cut by these cutter blades 3.3. The left side of the cut wire W is called a wire Wl, and the right side is called a wire W2. The proximity movement distance of the blade bodies 1 and 2 is sufficient to cut the wire W and is such that the strip plates 4 and 5 do not hit the wire W.

Thereafter, as shown in FIG. 4(c), the left clampers 6 and 7 with the wire rods W 1 and W 2 still clamped are slid in a direction to separate them by a predetermined distance. The sliding distance of the left clamper 6 is a distance corresponding to the strip length Q1 of the left end of the wire Wl as shown in FIG.
The length from the left end of the strip to the left strip blade 4 is defined as the strip length Q1. Similarly, the slide distance of the right clamper 7 is the distance corresponding to the strut length ρ2 of the right end of the wire W2 as shown in FIG. The length from the right end to the right strip blade 5 is defined as strip length Q2.

After that, as shown in the same figure (d), the upper and lower blade bodies 1.2
further move closer by a predetermined distance,
The strip blades 4 and 5 are cut into the covered portions of the wires Wl and W2. Blade body! , 2's proximity movement distance is
The stripping blade 4.5 cuts the coating at a distance corresponding to the thickness of the wires Wl, W2, the thickness of the coating, etc., and is sufficient to strip the coating.

After that, as shown in the same figure (e), the strithop blade 4.5
While cutting the clamper 6.7 into the covering portion, slide the clamper 6.7 further away by a predetermined distance. The sliding distance of the left clamper 6 is equal to or greater than the strip length ρl, and the covering portion of the right end of the wire Wl is reliably stripped. Similarly, the sliding distance of the right clamper 7 is equal to or greater than the stripping length Q2, and the covering portion of the left end of the wire W2 is reliably stripped.

After that, release the blade body 1.2 and clamper 6.
, 7, and then send the wires Wl, W2 to the left. Then, by repeating the operations described above using the latter wire W2 as the wire W, wires with both ends stripped are successively produced.

As described above, the wire rod W can be cut and the wire rod Wl , W2 performs stripping processing for both terminals. By servo-controlling the distance of proximity movement of the blade main body in the second step, it is possible to perform strobulation corresponding to the thickness of the wire W and the thickness of the coating, and also the sliding distance of the clampers 6 and 7 in the first step. By controlling the servo, it is possible to accommodate various strip lengths.

Note that by providing only one of the left and right strip blades 4.5, the wire can be processed so that only one end is stripped.

[Effects of the Invention] As explained above, the wire rod end processing method of the present invention combines the two-step approach movement of the blade body, the clamping action of the clamper, and the two-step sliding action of the clamper, and By controlling the amount of movement, the amount of cut into the wire coating and the strip length of the coating can be set arbitrarily, making it possible to process wires with various thicknesses and strip lengths. .
