Description

[Detailed Description of the Invention] The present invention relates to a press device comprising a press body and a roll feeder.

Conventionally, as shown in FIG. 1, this type of press apparatus is known in which a roll feeder B having a power source is directly attached to a press body A, and materials are sequentially fed into the body A.

With this structure, since the roll feeder B and the press body A are integrated, there is no relative displacement between the roll feeder B and the press body A, resulting in good material feeding accuracy.

However, if the roll feeder B itself becomes large and heavy, it will be difficult to attach it to the press body A, and vibrations will be transmitted directly to the roll feeder B when punching the material with the press body A, which will have an adverse effect on the roll feeder B. There is.

In order to improve these drawbacks, a press apparatus has been proposed in which a roll feeder B is installed separately from the press body A, as shown in FIG.

However, with this structure, relative displacement occurs between the roll feeder B and the press body A, resulting in poor material feeding accuracy.

In particular, as shown in Figure 2, the press body A is
If the roll feeder B and the press body A are installed through the press body A, the deflection of the press body A during press punching increases, and the relative displacement between the roll feeder B and the press body A increases, further deteriorating the material feeding accuracy.

The present invention was developed in view of the above circumstances, and its purpose is to provide a press device in which the press body and roll feeder are installed separately, in which the relative displacement between the press body and the roll feeder can be reduced. That's true.

Embodiments of the present invention will be described below with reference to FIGS. 3 and 4.

The press body 1 is installed on a base 2 such as a floor surface through a vibration isolator 3, and the roll feeder 4 is installed on the base 2 through a vibration isolator 3.
and the roll feeder 4 are connected via a parallel four-bar link 5.

That is, one end of a pair of upper and lower links 7, 7 is pivotally connected to the rib 6 of the press body 1 with pins 8, 8, and the other end of the pair of links 7, 7 is connected to the rib 9 of the roll feeder 4 with a pin. 10, 10 are pivotally connected, and each pin 8, 8, 10, 10 is located at each vertex of a parallelogram.

Therefore, the distance L between the center of the press body 1' and the center of the roll feeder 4' is always constant regardless of the position of the press body 1, as shown in FIG. No displacement occurs.

Therefore, the material can be fed with high precision by the roll feeder 4.

On the other hand, in the conventional structure shown in FIG. 2, when the press body 1 is displaced, the distance L changes to L', resulting in a relative displacement of S.

The present invention is as described above, and since the press main body 1 and the roll feeder 4 are respectively installed on the base 2 via the vibration isolating material 3, each can be freely displaced with respect to the base 2, and both are arranged in a pair of upper and lower positions. Since they are connected by a parallel four-bar link 5 having links 7, 7, the roll feeder 4 also displaces following the displacement of the press body 1, and no matter what position the press body 1 changes to, the press body 1 and the roll feeder are connected. 4 is always constant.

Therefore, the press body 1 and the roll feeder 4
Even though the press body 1 and the roll feeder 4 are installed at the base, the relative displacement between the press body 1 and the roll feeder 4 can be reduced to improve material feeding accuracy.

In addition, since the press body 1 and the roll feeder 4 are connected by the parallel four-bar link 5, which has a pair of upper and lower links 7, 7, no unreasonable force is applied to the connection portion, and no breakage occurs. .
