JPS595464Y2 - clamper device - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a clamper device for a press.

As a clamper device, it can be used to slide a mold, clamp it to a bolster, or clamp a bolster to a bed, etc.
Its usage is diverse.

Conventionally, there have been two types of clamper devices: one in which the clamp rod is rotated around the rod, and one in which the clamp rod is swung from the base.

This is also to prevent the clamp rod from interfering with the loading and unloading of molds, etc.

The present invention belongs to the latter category. The present invention provides a safe clamping device that will not damage the clamping device even when a foreign object gets between the clamping rod and the object to be clamped, such as a mold, or when the clamping rod interferes with other parts. This is what we provide.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be explained in detail below based on the drawings.

In FIG. 1, a piston rod 1 is guided by a cylinder 2 so as to be movable up and down.

The cylinder 2 is provided, for example, in a moving bolster 6,
You are guided to ascend and descend freely.

A spring 4, on which the clamp rod 3 is swingably attached to the head of the cylinder 2, is installed between the stepped portion 1a of the head of the piston rod 1 and the bottom 2a of the cylinder 2.

A spring 5 connects the head 1a of the piston rod 1 and the clamp rod 3.

The spring 7 is installed between the stepped portion of the outer surface of the cylinder 2 and the bottom portion 6a of the moving bolster 6.

The upper surface of the head of the cylinder 2 is arranged so as to come into contact with the stepped portion 6b of the bolster.

In this embodiment, the cylinder 11 is placed on the bed 8 of the press.
The T-shaped groove provided at the head of the piston rod 10 and the T-shaped portion at the lower part of the piston rod 1 are fitted into the T-shaped groove.

In FIG. 3, the head 3a of the clamp rod 3 is T-shaped and has a shape and size to engage with the groove of the mold 9.

In FIG. 1, the moving bolster 6 travels with molds loaded thereon, and when it reaches a fixed position on the bed 8, the moving bolster 6 is lowered by a lifting device (not shown) and lands on the bed.

At this time, since the top surface of the head of the cylinder 2 of the piston rod 1 is in contact with the stepped portion 6b of the moving bolster 6,
Push down the piston rod 10.

Due to the action of the cylinder 11, the piston rod 1 is lowered via the piston rod 10.

Along with this, the clamp rod 3 is swung by the spring 5 and stands up, and FIG. 2 is a diagram when the piston rod stands up.

) When the stepped portion of the piston rod 1 comes into contact with the bottom portion 2a of the cylinder 2, the cylinder 2 descends via the piston rod 1.

The head 3a of the clamp rod 3 engages with the mold 9, and the mold 9
, the moving bolster 6 is tightened to the bed 8.

To release the tightening, push the clamp rod 3 with the spring 5,
The operation is opposite to that described above except that the clamp rod 3 is tilted by the rotational force due to the gravity of the clamp rod 3.

In this embodiment, the cylinder 2 is provided on the moving bolster 6, but the cylinder 2 is provided on the bed 8 and the moving bolster 6 is provided.
It may be used to fasten to the bed 8.

In this case, the piston rod 1 and the piston rod 10 may be integrated.

Since the present invention has the above-described structure, even if a foreign object gets between the clamp rod 3 and the member to be clamped, or if the clamp rod 3 interferes with another member, it will not be damaged. We were able to provide clampers.

This is especially effective when aligning the mold and bolster with the bed.
