Abstract

PURPOSE:To select the rate of pressurizing properly and to deal with the suitable pressing effect for the object to be worked by fitting member for adjusting the top and bottom stop point of a ram pivotally to the arm of a toggle mechanism which moves the ram vertically. CONSTITUTION:A ram 11 is assembled in the head part of the frame 10 of a press device. A toggle mechanism 13 which moves the ram 11 vertically is constituted of a crank 14 and arms 15-17, and is fitted axially to a movable member 19 located in a hole 18 for accepting the arm 16. The arm 17 is fitted pivotally to the ram 11. The arm 15 is fitted axially to the crank 14. The member 19 is brought into contact with a height adjusting dial 20 providing a rate of deviation caused by rotation on the projecting end side from the hole 18. An adjusting mechanism 12 is formed of said member 19 and dial 20. In the stage of exerting a pressurizing effect upon the object to be work, the position of the member 19 is set by the rate of deviation caused by rotation of the dial 20 to obtain the suitable top or bottom stop point of the ram.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a press device, and particularly to a press device having an adjustment feature such that the vertical stopping point of the ram is delayed by adjustment.

Conventionally, as an Oll press device, for example, 1g1i
There is also O as shown in QK. This is a frame (1) K built-in * rim (frost, thorn ρ mechanism 〇 part ta
j! lc crank (3701i & 6゜ that moves up and down, that is, the crank (3) has three arms (4) t5) (with the phrase thorn # mechanism tsigt, one end of the arm 4 is fixed The end (7JK%) is small because one end of the arm is pivoted to the ram (2).

Therefore, the vertical stopping point of the ram 12) is constant! Depending on the material to be rotated and pressurized, select the vertical stopping point of the rotation (naturally, Ramsel) (870 m1 displacement JttC), and the vertical direction O stopping point of 1 Ml11.
It is something we meet. However, it would take four hours to select the amount of stopping points to be claimed.

For this reason, a nine press device has been developed in which the upper and lower stopping points r4 of the ram can be appropriately selected.

The present invention was made in view of the above points, and has 7 frames! It is said that the ram inserted in the trap is moved up and down in conjunction with a toggle mechanism consisting of a crank and an arm.
In the press device equipped with an adjustment mechanism for the vertical stop point of the ram, the adjustment mechanism is located in the receiving hole of the frame, and on the -m side thereof, there is a movable member pivoted to the arm of the toggle mechanism; The protruding Mll from this receiving hole is made up of a height dial that comes into contact with the movable member. The present invention provides a press device in which the vertical stopping point of the ram can be varied and, in addition, the vertical stopping point of the ram can be adjusted via the toggle mechanism.

Hereinafter, one embodiment of the press apparatus of the present invention will be explained with reference to the drawings.

In FIG. 2, OI is the frame of the press device, and its chain part incorporates two rams aυ, which are vertically movable parts, and is equipped with an adjustment mechanism 0 for the vertical stopping point of the ram aυ.

Since the vertical movement of the ram (2) is obtained by the toggle mechanism α3, the toggle mechanism 13, in the case shown in 1, is composed of a crank Q4) and an arm (as). The arm a@ is located in the receiving hole qI in the movable member portion, and the primary arm fins are each pivotally attached to the ram 0υ. The two arms are commonly pivoted at one end to the crank α, and at the other end to the arm 〇〇αη.

The movable member a field is a convex end from the receiving hole a field,
Since the height adjustment dial (7) is brought into contact with the height adjustment dial (7) having a rotational deviation amount t, the adjustment mechanism a2 is adjusted to mWt by the movable member Sumiyu and the quotient adjustment dial (2).

In this case, the height adjustment dial gJFi has an amount of rotational deviation as described above, and in the one shown in the figure, eight levels of rotational deviation can be obtained by forming an octagon. I'm trying to be able to do that.

If necessary, the motor (2) is directly connected to the rear axis Qυ of the height adjustment dial (to), and in addition, a potentiometer or the like that memorizes the rotational position can be installed to enable electrical remote control. .

Well, the height adjustment dial (2) is definitely # against the movable member a hot water! In order to be in contact with each other, in this embodiment, as clearly shown in FIG. 3, a spring is provided between the movable member U and the receiving hole. Furthermore, the height adjustment dial (2) can also have an eccentric circular shape as shown in FIG.

This also has a stepless meaning.

The position of the can is set so as to obtain an appropriate vertical stopping point for the ram (11). That is, as shown in No. 51N(b), the pressure jiJ can be selected as appropriate.

Note that the dark blue figure 6 shows a modified example, so the toggle mechanism U
For rowing, a crank mechanism commonly called the U-ken was used. Accordingly, the positions of the 6J moving member 1 and the height+# adjustment dial are accordingly different. That is, the crank mechanism 03 has a crank shaft and an arm TJ.
! The arm (2) on the buttock rotates as the crank rotates, and its fixed pin (to) guides 1 m.
1elK gives vertical movement to arm (2) and 250υ.

As explained above, the present invention is aimed at a press machine equipped with a S* machine that can adjust the vertical stop point t for the ram, and therefore it It has the advantage of being able to deal with pressurizing effects, and being able to deal with this without reducing work efficiency when processing eK-products.
