JPS5828661Y2 - 2D and 3D combined material supply device in transfer press - Google Patents

Description

[Detailed description of the invention] The present invention relates to a material feeding device that can be used in both two-dimensional and three-dimensional cases when feeding material fed from a chute to an idle stage S in front of a work stage W in a transfer press. It is something.

Conventional cold forging transfer press material supply devices do not have a structure that can be switched between 2D and 3D.
Generally, for three-dimensional feeding, as shown in Figure 1, a stopper 3 for the material sent from the chute 2 is provided on the chute 1 on the feed line, and the material 4 stopped there is held by a grip finger. clamp, lift,
The material was conveyed by dodging the stopper, but since the height of the stopper can only be kept below the lift stroke, it is not possible to feed material with a high height. In order to supply the same, a different supply method must be used, making it impossible to share equipment and requiring a long set-up time.

The present invention eliminates this drawback and allows two-dimensional transfer presses to be used for both two-dimensional and three-dimensional feeding using the same device.
The present invention aims to provide a dimensional and three-dimensional material supply device.

To explain the drawings of one embodiment of the present invention, materials are fed and stacked using a chute 5 onto a shim 16 on the feed line, as shown in FIG. As shown in the figure, it is conveyed by clamping it with grip fingers 8.

A traverse 10 is installed at the end of the feed bar 9, and one side is fixed on the traverse 10, and the other side is guided by a guide 25 whose base plate 11 is fixed to the base plate 11. A slider 15 is provided that is slidable and has a notch 13 so as not to hit the chute 12 provided on the base plate 11, and has guides 14 provided at both end portions.

Grip fingers 8 are fixed to the center sides of the guides 14, and rollers 16 are erected by holders 17 at the opposite ends, and a ramp slider 18 is attached to the rollers 16, which are slidable in the clamp-unclamp direction. .

Further, two pins 19 are embedded in the clamp slider 18, and a spring 21 is installed between each pin 20 provided at the end of the guide 14.

An L-shaped finger 24 is installed on the feed bar 9 facing the roller 16, and the L-shaped finger 24 slides while being guided by a fixed guide 22 and whose position is adjusted by an adjustment bolt 23. When the feed bar 9 makes a clamping motion, the roller 16 is pushed by the back 24a of the L-shaped finger 24, and the clamp slider 18 is slid, and the material 7 is clamped by the grip finger 8. Next, when the feed bar 9 lifts, the clamp slider Since row 216 is attached to 18, row 216
is merely rotated by the L-shaped finger 24, and the grip finger 8 advances the material in its groove 1 without lifting.

When the advance is completed, the feed bar is lowered and unclamped, the clamp slider 18 returns to its original position by the spring 21, unclamps the material, and returns with the return of the feed bar.

Material can be fed in the same way even when the feed bar moves in two dimensions.

Furthermore, if the size of the material changes, the chute 5 and the grip fingers 8 attached to the clamp slider 18 can be replaced.

According to the present invention, a lift stroke was conventionally used as shown in Fig. 1, but if the height of the material was higher than the lift stroke, the material would fall down before the stopper, limiting the material that could be supplied. Since there is no such limitation, a wider range of height materials can be provided.

There is also a method in which the bottom material of a stack of materials is pushed out using a pusher, but this method has the disadvantage that the material will fly out when the speed increases, but with this method, the material can be grasped securely, making it more expensive. Good for speed too.

(Does not require a product holder) Also, it can be used in common with a type of transfer press that switches between 2D and 3D, and can be mounted on the chute and slider to handle changes in the size of the material. This has the advantage that it can be handled simply by replacing the grip fingers.
