Abstract

PURPOSE:To undo a bundle simultaneously with shearing, and to cut exactly a wire rod to pieces by inclining a cutting edge with respect to an axis of the wire rod, and also forming stepwise a step difference along the cutting edge, on the surface opposed to a wire rod bundle of at least one edge. CONSTITUTION:A wire rod bundle 1 of a wire rod 1a bundled by a grid band 2 is fed out in the direction A, the wire rod bundle 1 is pressed firmly against a receiving base 5 by a holding plate 6 and fixed, and thereafter, a moving edge 4 is moved in the direction C and brought to reciprocating driving in the direction roughly vertical to the axis of the wire rod 1a so as to pass each other with respect to a fixed edge 3, and the wire rod bundle 1 is shorn. In this case, the band 2 is cut diagonally by inclining a cutting edge of the edges 3, 4 with respect to the axis of the wire rod 1a, and also the wire rod bundle 1 is shorn to pieces by a step difference 4a formed stepwise along the cutting edge, on the surface opposed to the wire rod bundle 1 of the edge 4. In this way, a bundle of the wire rod can be uncoupled effectively at the same time as shearing of the wire rod.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shearing machine for a wire bundle formed by bundling a plurality of wire rods, and is particularly designed to shear the wire rods and simultaneously remove the bundle.

A grid band (width 4
When shearing a bundle of wires held together at a constant distance (approximately 0m) into short pieces (approximately 25 to 50W) and shredding each wire into small pieces, conventional shearing machines It was sheared in a direction perpendicular to the axis of the As a result, the grid band remains intact or sliced at the grid band attachment point.
The problem is that the wire rod strips in that area remain tied to the grid band and become a large lump, and the lumps clog the strip transport path, causing problems in later processing of the strips. there were.

The present invention was made to solve all of the above problems.
It is an object of the present invention to provide a shearing machine for a wire bundle, which can reliably shred the wire by shearing the bundle of wire and simultaneously removing the bundle. To achieve this object, a wire bundle shearing machine according to the present invention has a configuration that includes a pair of blades for shearing a wire bundle formed by binding wire rods in a direction substantially perpendicular to its axis. The cutting edge of the blade is inclined with respect to the axis of the wire rod, and a step-like step is formed along the cutting edge on the surface facing at least one of the nuclear force wire bundles. Particularly, one embodiment of the present invention will be explained in detail below with reference to the drawings. FIG. 1 is a front view of an embodiment of the present invention, FIG. 2 is a side view thereof, and FIG. 3 is a plan view thereof. In the figure, reference numeral 1 denotes a sheared wire bundle, in which a large number of wire rods 1a are bound together with grid bands 2 and integrated. 3 is a fixed blade, 4 is a movable blade, 5
is a pedestal, and 6 is a holding plate, and the wire bundle 1 is pressed and fixed to the pedestal 5 by the holding plate 6. The fixed blade 3 is fixedly attached to the pedestal 5, while the movable blade 4 is positioned so as to sandwich the wire bundle 1 fixed to the pedestal 5 with the fixed blade 3. The fixed blade 3 and the movable blade 4 have cutting edges formed at opposite corners, and the movable blade 4 is reciprocated in a direction substantially perpendicular to the axis of the wire 1a so as to pass the fixed blade 3 by a drive device (not shown). Then, the wire bundle 1 is sheared.

In addition, as shown in Fig. 1, the fixed blade 3 has a thin upper part and a thick lower part, and conversely, the movable blade 4 has a thick upper part and a thin lower part, so that the cutting edge is aligned with the axis of the wire 1a. tilt it against the Further, as shown in FIG. 2, the movable blade 4 is formed with a plurality of steps 48 in a step-like manner along the cutting edge on the surface facing the wire bundle 1, so that the movable blade 4 can move in the direction of the wire bundle 1. He is trying to engage with the wire bundle 1 sequentially from the front step 4a.

Next, to explain the operation, first, the wire bundle 1 is sent out in the direction of arrow A, the tip is made to protrude a predetermined amount from the fixed blade 3,
The holding plate 6 is moved in the direction of the arrow B and the wire bundle 1' is firmly pressed against the holder 5 and fixed. Thereafter, the movable blade 4 is moved in the direction of arrow C to completely shear the wire la protruding from the fixed blade 3. At this time, the cutting edges of the fixed blade 3 and the movable blade 4 are inclined with respect to the axis of the wire 1a, so when the grid band 2 is cut at the attachment point, the grid band 2
The wire material 1a is cut diagonally to remove the bundle, and is also finely crushed step by step by the step-like step 4a of the movable blade 4, so that the sheared pieces of the wire material 1a can be reliably broken up into pieces.

In this embodiment, the step-like step 4a is formed on the movable blade 4, but the step may be formed on the fixed blade 3 instead of on the movable blade 4, or it is also possible to form the step on both.

As described above in detail with reference to one embodiment, according to the present invention, it is possible to effectively unbind the wire at the same time as shearing the wire, thereby reliably separating the sheared pieces of the wire. be able to.
