る。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a braided shield (hereinafter referred to as a "braid") stripped from a terminal portion of a shielded electric wire.
The present invention relates to a braid cutting method and a braid cutting device for cutting a braid into a predetermined length.

Description of the Related Art Braid cutting at the end of a shielded electric wire is performed by gripping the vicinity of a cut point of the braid peeled off at the end of the electric wire with a cylindrical inner blade divided into two parts, and further exposing the exposed braid from the outside with a punch. Hit the braid to open the tip of the braid, and then penetrate the braid opening pipe inside the braid from the end of the electric wire to radially open the cutting area of the braid, and in this state, open the braid opening pipe urged by the spring. The inner blade enters the cylindrical outer blade provided at the tip of the holder while being pushed into the holder by the blade, and the braid is sheared by the inner blade and the outer blade.

停止のトラブルを招く。In the above-mentioned method, when the stripping length (cutting length) of the braid becomes long, a processing trouble is apt to occur. Even if you open the braided pipe inside,
In the braid in the region away from the tip, the entanglement of the strands cannot be unwound, and as a result, when the cutting length is increased, the braid opens only on the tip side. As a result, the insufficiently open area is caught between the end faces of the outer blade and the inner blade, and is crushed in a lantern shape (buckling in a wavy manner), resulting in uneven cutting, poor cutting such as uncut cutting, and trouble in stopping cutting. Invite.

Although a mechanism for tearing off the cutting debris and a hood for sucking and collecting the torn debris are provided, this complicates the apparatus.

However, the devices developed so far can easily cope with a type change (change of cutting length and wire diameter). I can hardly find anything I can do. If it takes time for setup change and adjustment due to the change of the product type, the operation rate of the apparatus in small-lot production of many products becomes poor, which is not preferable.

In the braid cutting method of the present invention, the exposed braid is held with the shielded wire subjected to the outer skin peeling at the processing center with a nail functioning as a punch, and loosened,
Thereafter, a cylindrical braided floating pipe having an inner blade on the outer periphery is sunk into the inside of the braid, and the squeezing is performed by lightly shrinking the braid exposed by the force transmitted from the pipe in the longitudinal direction of the electric wire to expand the diameter. After the burrow is completed, the cylindrical outer blade through which the electric wire has been passed is moved and rubbed against the inner blade, and the outer blade and the inner blade float the braid and cut the braid covered on the pipe.

A chuck to be held, a cylindrical outer blade disposed in front of the chuck, a cylindrical braided floating pipe having an inner blade at an outer periphery of a distal end portion arranged in front of the electric wire, and an outer peripheral end of the pipe. A scrap remover that can be slid freely, an actuator that pushes the braid floating pipe and the scrap remover toward the electric wire, a braid strike unit that strikes the braid from the outside with a plurality of claws, and the braid strike unit with the machining center as the fulcrum A rotary drive mechanism for rotating the outer blade in the longitudinal direction of the electric wire, and a feed mechanism for independently moving the braiding unit in the longitudinal direction of the electric wire. Then, the claws of the braiding unit hit the exposed braid from the outside while moving around the electric wire to open the tip of the braid.Furthermore, with the claws gripping near the braid end and centering, the braid floating pipe After the tip enters the tip of the braid and the claw opens and retreats, the braid floating pipe extends into the inside of the braid until the inner blade on the outer circumference reaches the set position, and at this position the outer blade moves toward the inner blade. The braid is cut by the outer blade and the inner blade by moving, and the scrap remover relatively retracted when the braided floating pipe is sunk is relatively advanced when returning the braided floating pipe to remove the braid cutting debris on the pipe. It is configured to push off.

なされる。According to the present invention, the braid is not opened radially, but is gently pressed and shrunk in the longitudinal direction of the electric wire by the moving force of the braid floating pipe, and floated inside the braid having an increased inner diameter and reduced insertion resistance. Let the pipe penetrate. Then, in this state, the outer blade is moved to cut the braid floating on the braid floating pipe. Therefore, the braid is prevented from being compressed in the longitudinal direction of the electric wire between the inner cutter and the outer cutter and crushed like a lantern, and stable cutting without variation and uncut portion is stably performed.

要になる。Other functions and effects of the cutting device according to the present invention will be described below. (1) After hitting the braid with the claws of the braid hitting unit to open the tip of the braid, centering the end of the wire with the same claws and inserting the braid floating pipe into the tip of the braid, an insertion error of the pipe occurs. Absent. (2) Since the braid cutting debris to be left on the braid floating pipe is forcibly pushed off by the debris dropper, the processing of the cutting debris is ensured, and the operation trouble of the apparatus due to the bite of the debris does not occur. (3) If the position of the positioning tool can be controlled electrically, the cutting length of the braid can be set arbitrarily. (4) Braid hitting unit is also used as a positioning tool, and the position and the rotation angle of the claws can be controlled electrically. The spread of the braid tip by hitting is optimized and the braid floating pipe is unscrewed. Can be smoothed, and the apparatus can be simplified. (5) A braided floating pipe provided with a scrap remover and an outer blade in a cartridge can quickly respond to a change in the wire diameter by exchanging the cartridge, and does not require any adjustment accompanying setup change.
