Description

[Detailed Description of the Invention] The present invention relates to a lower die of a striking machine that allows a collar locking fitting etc. to be firmly attached to an interlining without using a washer.

Conventionally, the lower die of a punching machine for attaching a collar locking fitting to the interlining for attaching a collar to the stand-up collar of school uniforms, etc., has a recess into which a washer is inserted on the upper surface, and a recess below the recess into which the washer is inserted. In general, a structure with a receiving metal fitting for bending and guiding the legs of the collar locking metal fitting etc. is widely used, and a washer is required to attach the collar locking metal fitting etc. to the interlining using the lower mold. It is.

In addition, the legs of the collar locking fittings are bent inward after passing through the interlining and washer, so the bent portions of the legs protrude toward the outer fabric side beyond the washer, and the collar locks. The uneven shape of the part where fasteners and the like are attached to the interlining becomes perceptible through the outer material, impairing the aesthetic appearance and causing a decline in the product value of school uniforms and the like.

This invention does not use washers at all, and once
By bending the leg that has passed through the interlining and pressing the bent leg so that it passes through the interlining in the reverse direction, the collar locking fitting etc. can be firmly attached to the interlining, thereby solving the above drawbacks. This is what I did.

Hereinafter, embodiments will be described in detail with reference to the accompanying drawings showing examples.

The cylindrical neck 2 has a large-diameter collar retaining portion 3 integrally provided at one end thereof, and a large-diameter collar retaining portion 3 having a conical inner surface with a gentle gradient outwardly expanding at the other end. A base 4 is integrally provided, and a plurality of legs 5, 5, . . . are vertically provided at equal intervals on the peripheral edge of the base 4.

The legs 5 have their tip portions formed into sharp points capable of penetrating the interlining 10, and are bent to have a V-shaped cross section to improve the strength of the sharp portions.

The upper mold 6 is held in a predetermined position on a machine stand (not shown) directly above the lower mold 7 so that it can be raised and lowered by a drive means (not shown), and the neck 2 of the collar locking fitting 1 is attached to the lower surface of the upper mold 6. and collar retainer 3
A recess 8 is provided through which the recess 8 can be inserted.
The balls 9, 9 are biased against each other so as to face a predetermined position on the inner side of the collar, so that the collar locking metal fitting 1 can be removably locked to the upper mold 6 with a slight force, and the collar locking metal fitting 1 can be removably locked to the upper mold 6 with a slight force. It is designed to prevent natural falls.

The operation when attaching the collar locking fitting 1 to the interlining 10 using the punching machine having the above configuration is as follows.

First, while holding the upper mold 6 in the raised state, the interlining 10 is placed on the upper surface of the movable guide plate 16 of the lower mold 7, and the collar locking fitting 1 is inserted into the recess 8 of the upper mold 6.
By locking, preparation for the installation operation of the collar locking metal fitting 1 is completed.

Thereafter, by lowering the upper mold 6 using a drive means (not shown), the collar locking fitting 1 can be attached as described below.

That is, the member 1 descends together with the upper die 6, and the sharp parts of the legs 5, 5, . . . contact the interlining 10 first.

Here, since the interlining 10 is clamped between the upper surface of the movable guide plate 16 and the upper surface of the movable guide plate 16 by a presser rod (not shown) and is held under tension in a horizontally immovable manner, the upper mold 6 cannot be further lowered. Therefore, legs 5, 5... are interlining 1
0 from above and formed by the inner ends of the movable guide plates 16, 16 whose sharp parts face each other.
come into contact with

By further continuing the lowering of the upper die 6, the legs 5, 5... are bent inward along the inclined surface, and the sharp parts engage with the protrusions 21, 21, so that the legs 5, 5... are bent slightly upward. (See Figure 4).

In this state, the lower surface of the upper mold 6 is in contact with the upper surface of the interlining 10, so by further lowering the upper mold 6, the first receiving fitting 11 can be lowered against the springs 14, 14.

When the first metal fitting 11 descends, the inclined surfaces 19, 19
engages with the inclined surface 25 to slide the movable guide plates 16, 16 against the springs 17, 17, and the bent legs 5, 5... of the collar locking fitting 1 are connected to the fixed guide plate 22.
