Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a completely new upper die rod for a hook and hook striking machine.

In conventionally used hammering machines such as hook hooks, an upper die rod is provided above the holder for the washer, etc., so that it can only be raised and lowered, and the upper die rod is placed relatively close to the position facing the upper die rod in the raised position. A feeding device such as a hook or hook is provided.

Therefore, by lowering the upper die rod once after feeding the hook hook or the like to the upper mold rod by the feeding device, the driving operation of the hook hook or the like can be reliably performed.

However, when the driving operation is finished and the upper mold rod is raised, it is necessary to remove the hooks attached to the upper mold rod. There were drawbacks such as the user's hand, fingers, etc. being damaged during the extraction operation.

The present invention solves the above-mentioned drawbacks by making the upper mold rod horizontally rotatable and always facing the feeding device such as a hook hook. DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples will be described in detail with reference to the accompanying drawings.

FIG. 1 is a front view of a driving device such as a hook hook equipped with the upper mold rod of the present invention, and shows a driving device body 3 equipped with a pedestal 2 and an upper mold rod 1, and a hook hook mounted on the upper mold rod 1. It is composed of a feeding device 4 that supplies, etc.

In addition, 5 is a base plate that supports the punching machine body 3 and the feeding device 4, 6 is an operating lever provided on the punching machine body 3, 7 is a spring that always urges the upper die lever 1 upward, and 8 is a hopper ( This is a guide rail that supplies one hook or the like 9 to the feeding device 4 from (not shown).

FIG. 2 is an enlarged front view of the upper mold rod 1, FIG. 3 is a central vertical sectional view thereof, FIG. 4 is a cross-sectional view taken from FIG. 3, and FIG. 5 is a bottom view.

The upper die rod 1 includes an elevating rod 10 that is non-rotatably supported on the punching machine body 3 and can be raised and lowered, and a support portion 11 such as a hook that is supported horizontally rotatably at the lower end of the elevating rod 10. The details are as follows. That is, the lifting rod 10 has a hole 12 bored in its lower part for attaching the support part 11, and the lower half of the hole 12 is a large diameter part 13, and is threaded so that it can face the small diameter part 13'. A shaft 14 is provided.

The support part 11 is placed at a predetermined position on the upper surface of the main body 16, which has a retaining plate 15 on the lower surface that holds the hook 9, etc.
A shaft 17 that can be inserted into the small diameter portion 13' is erected,
Further, an annular groove 18 is bored at a predetermined position of the shaft 17 to fit with the screw shaft 14.

Reference numeral 19 denotes a coil spring located in the space formed by the shaft 17 and the large diameter portion 13, with its upper free end fixed to the lifting rod 10 and its lower free end fixed to the main body 16. There is.

Further, 20 is a stop flange vertically disposed at a predetermined position on the lower surface of the lifting rod 10, 21 is a screw shaft that passes through the holding plate 15 and is attached to the main body 16, and 22 is the screw shaft 2.
1 is loosely fitted to press the holding plate 15 against the main body 16.

The relationship between the coil spring 19 and the stopper 20 is such that the support part 11 is rotated clockwise around the lifting rod 10 as shown in FIG. Thus, the support portion 11 is directly opposed to the feeding device 4.

The operation of the driving device such as a hook hook having the above structure is as follows.

After placing a washer, etc. 23 at a predetermined position on the pedestal 2, and further placing a fabric 24 covering the pedestal 2 and the washer 23, the feeding device 4 is reciprocated to place a hook, etc. on the support part 11. 9 and completes the driving preparation operation.

Therefore, if the upper mold rod 1 is then lowered against the elasticity of the spring 7 by operating the operating rod 6, the legs of the hooks etc. 9 penetrate the fabric 24, and then the washers etc. 23 are removed. By engaging and bending, completing the driving operation, and releasing the operating rod 6, the fabric 24 with hooks and the like 9 driven therein is raised together with the upper mold rod 1.

Next, if you hold the right side of the fabric 24 and pull it toward you, the support part 11 will rotate against the coil spring 19 as shown in FIG.
By pulling toward you together with the fabric 24,
Hands, fingers, etc. can be removed without fear of touching the feeding device 4.

After the hook 9 is removed, the coil spring 19 returns the support portion 11 to its original position as shown in FIG. 5a, thereby preparing for the next driving operation.

The embodiment described above is such that the support part 11 can rotate approximately 90 degrees, but the rotation angle can be changed by, for example, changing the shape of the support part 11 and changing the position where it engages with the stopper 20. Therefore, it is also possible to make the rotation angle 180 degrees.

As described above, in the present invention, since the support part can be rotated by a predetermined angle, the support part can be easily shifted from the position directly facing the feeding device when removing a hook hook, etc., and the removal work is facilitated. It also has the unique effect of being safe.
