Description

The stroke adjuster for a press working}

The present invention relates to a press mold, and more particularly, to a stroke adjusting device installed below the press mold.

Since various molds are applied to the press mold according to the shape (height) of the press product, it is necessary to adjust the stroke (gap between the upper mold and the lower mold), and the mold type is different according to the shape of the product. (SIZE)), especially in the case of small production, this mold change must be made continuously.

As such, the press mold is a method in which a mold (lower mold) is settled by clamping the lower mold by using steel block as much as the stroke of the upper mold in the press die in order to install the mold in the press. It is taken as follows, looking at this in detail as follows.

As is well known, the press mold needs to adjust the stroke so as to conform to the specifications according to the shape of the product to be molded, and, according to this necessity, the press die (Dle) usually has a block having a specification that conforms to the specification (height) of the mold. (Block) is installed to compensate for insufficient space.

By the way, when replacing the mold, in order to adjust the stroke according to the mold of different standard (height), a separate block suitable for each mold must be installed in the press die first, so that the work time due to the mold replacement is wasted. This caused a number of problems, such as reduced productivity.

In order to solve this problem, a device for adjusting the stroke of a press mold has been previously proposed. (Registration Utility Model Publication No. 0151728)

However, the existing device has a number of disadvantages and problems, such as a complicated configuration of the control device for the stroke control and a high risk of malfunction due to the relatively large number of parts required development of a new device.

In this design, the fixed stroke of the press mold is used as the basic dimension, and the slide plate coupled to the jack compensates for the insufficient space according to the mold standard (height). From this, it is intended to shorten the mold exchange time, thereby reducing the wear rate of the mold and the defective production rate of the parts by economical benefits such as productivity improvement and stable mold setting.

The present invention provides a press mold with a stroke adjusting device comprising a slide plate on which a mold is installed on a press die, and a jack (JACK), which is a stroke adjusting means coupled to the slide play to lift and operate the slide plate on which the mold is installed. It is characterized in that the stroke adjustment is easily made according to the shape change (height) of the product to be made, and thus the advantages of the installation, dismantling, and replacement of the mold are described. Same as

1 is a block diagram showing an embodiment of the present invention, Figures 2a, 2b is an excerpt of the present invention, Figure 3 is a functional state of the present invention, Figure 4 is a sectional view of the main part of the present invention.

A slide plate 4 is installed based on a horizontal plane of the press die 1, and the slide plate 4 is coupled to slide upward and downward in a guide hole 1a which is vertically penetrated on the press die 1. To this end, a slide guide 7 is provided on the slide plate 4 and the guide hole 1a for guiding the up and down operation of the slide plate 4.

In addition, the slide plate 4 is coupled to the upper jack plate 3 of the jack 2, the slide plate 4 is seated on the jack plate (3) in accordance with the rising drive of the jack (2) As the jack plate 3 rises, the slide plate 4 rises to compensate for the stroke of the mold 5 according to the change of the product to be molded, which will be described later.

The jack 2 has a screw jack or the like, but is most preferably carried out with hydraulic, pneumatic or pneumatic lifting jacks.

In addition, the slide guide (7) for guiding this when the slide plate (4) is moved up and down on the guide hole (1a) of the press die (1) in the form of sliding coupling in a general male and female structure as shown in FIG. It can be carried out in various ways.

On the other hand, the clamp 6 is installed on the slide plate 4 to fix the mold 5 placed therein, and the clamp 6 for fixing the mold 5 is normally placed on the slide plate 4. Form a T-groove in it and install the clamp (6) there.

In the figure, reference numeral 8 denotes an upper mold, and 9 denotes a press head.

The present invention configured as described above does not need to install a separate block or the like to adjust the stroke according to the specification (height) of the mold 6 at the time of replacing the mold 5, thereby reducing the mold replacement work time. From this, we can expect productivity gains.

The present invention does not require the installation of a separate block for varying and adjusting the stroke according to the shape (height) of the mold 5 for forming a product.

That is, the present invention is to lift and move the slide plate 4 coupled to the upper jack plate 3 of the jack 2 by lifting and lowering the jack 2 according to the specification (height) of the mold 5. The die 5 is moved up and down on the horizontal surface of the press die 1 to adjust the stroke.

As described above, the present invention uses the jack 2 to move the mold 5 up and down so that the stroke is variable and adjusted.

Hereinafter, look at in more detail with respect to the operation of the present invention.

The slide plate 2 which is operated to slide up and down by the jack 2 is moved up and down about the horizontal plane of the press die 1 by the slide guide 7 formed in the guide hole 1a of the press die 1. The mold 5 is pushed up or down to compensate for the appropriate space according to the required size (height) of the mold 1.

The slide plate 4 is slidably guided up and down by the slide guide 7 with the guide hole 1a of the press die 1, and the stroke is variable and set by adjusting the distance with the upper die 8.

That is, since the mold 5 installed as the clamp 6 on the slide plate 4 operates in conjunction with the upper mold 8, the space is generated by varying and setting the stroke by moving and moving upward as the jack 2 as much as possible. There is no.

On the other hand, when dismantling and replacing the mold 6, the jack 2 is operated downward or the automatic release role is performed only by removing air or hydraulic pressure of the jack 2, so that the clamp 6 on the slide plate 4 is very released. Easy and quick dismantling and replacement of the mold (5) can be performed quickly and easily.

As described above, the present invention enables the adjustment of the stroke by the height of the mold 5 according to the product to be molded in the press mold to be performed very simply by the work using the jack 2, so that mold installation and dismantling, The operation time can be shortened for replacement, which can significantly improve the productivity, and the stable mold setting can reduce wear of the mold 5, reduce the defective rate of parts, and improve work convenience by simplifying the mold setting work. You can expect

In addition, since it can be applied to the press mold with a relatively simple configuration and low production cost, many effects such as being able to contribute widely to the production cost reduction effect of various parts can be expected.
