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 upper mold rod is raised after the driving operation, it is necessary to remove the hooks attached to the upper mold rod. There were drawbacks such as the hand, fingers, etc. being injured during the extraction operation.

The present invention solves the above-mentioned drawbacks by making the upper mold rod capable of wide rotation in the horizontal direction 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 machine body 3 equipped with a pedestal 2 and an upper mold rod 1, and a hook attached to the upper mold rod 1. It is composed of a feeding device 4 that supplies hooks and the like.

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 ( A guide rail (not shown) supplies one hook or the like 9 to the feeding device 4, and 10 is an elevating rod that supports the upper mold rod 1.

Upper mold rod 1 and lifting rod 10 which are the most important aspects of the present invention
The relationship is as follows.

The lifting rod 10 has a substrate 11 fixed to its lower end for attaching the upper mold rod 1, and a hole 12 for attaching the upper mold rod 1 to the substrate 11 at a position offset from the central axis of the lifting rod 10. At the same time, a stopper 13 is provided vertically at a predetermined position of the base plate 11 to restrict rotation of the upper mold rod 1.

The upper mold rod 1 has a holding plate 1 that holds a hook 9, etc.
A shaft 16 that can be inserted into the hole 12 is erected at a predetermined position on the upper surface of the main body 15, which has a shaft 16 provided on the lower surface.

In addition, 17 is the large diameter part 12' of the hole 12 and the shaft 1.
6, and has one free end fixed to the substrate 11 and the other free end fixed to the upper mold rod 1.

Further, 18 is a bolt that supports the shaft 16 on the base plate 11 without falling off, 19 is a screw shaft that loosely passes through the holding plate 14 and is attached to the upper mold rod 1, and 20 is loosely fitted to the screw shaft 19. This is a spring that presses the holding plate 15 against the upper mold rod 1.

The relationship between the coil spring 17 and the stopper 13 is determined by rotating the upper die rod 1 clockwise about the shaft 16 as shown in FIG.
3 to restrict the clockwise rotation, and then the upper mold rod 1
is arranged to directly face the feeding device 4.

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

After placing the washer 21 at a predetermined position on the pedestal 2, and placing the dough 22 covering the pedestal 2 and the washer 21, the feeding device 4 is reciprocated to attach the hook to the upper mold rod 1. etc. 9, thereby completing 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 22 and then the washers etc. 21 are removed. By engaging and curving, thereby completing the driving operation, and then releasing the operating rod 6, the fabric 22 into which the hooks and the like 9 have been driven is raised together with the upper mold rod 1.

In this state, if you hold the right side of the fabric 22 and pull it toward you, the upper mold rod 1 will open as shown in Figure 5b.
is rotated against the coil spring 17, so by pulling the hook or the like 9 forward together with the fabric 22, the hand, fingers, etc. can be removed without fear of touching the feeding device 4.

After the hook 9 is removed, the upper die rod 1 is returned to its original position by the coil spring 17, as shown in FIG. 5e, and is ready for the next driving operation.

The above has described an embodiment in which the upper mold rod 1 can freely rotate over a wide range.
For example, by changing the shape of the upper mold rod 1, it is possible to limit the rotation range.

As described above, since the support part of the present invention can be rotated by a predetermined angle, the support part can be easily moved from the position directly facing the feeding device when removing a hook, etc. By shifting the center axis of the upper mold rod from the center axis of rotation of the upper die rod, the amount of rotation can be increased, which has the unique effect of making the extraction work easier and safer.
