Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a mounting device for mounting and centering known tools on a single punching machine.

[0002]

2. Description of the Related Art In order to make holes having different cross sections and ring portions in a metal sheet material being processed, punching machines manufactured up to now are processed with a hammer of the punching machine. A template, which is interposed between the sheet material and the metal sheet to be formed, and which allows, for example, a slot, a hole having an elliptical cross section or the like to be formed in the sheet material, can be mounted.

[0003]

For each of the limbs and each of the templates, one for each hole, actually one for one kind of hole,
I have a punch. Although they work well, there is an inevitable increase in cost due to the wide range of choices of operation. Furthermore, not all punching machines currently on the market are compatible with tools produced by different manufacturers, and as a result, operators in the field often use multiple tools to ensure the working range. The punching machine will have to be equipped, and the manufacturing and maintenance costs will increase.

In addition to this, there is always a demand to obtain machines which give very high machining accuracy in the range of one-hundredth of a millimeter, but this characteristic is due to wear of moving parts and mechanical play. Due to the design problem of (1), it cannot be obtained with all known punching machines at present.

A technical object of the present invention is a mounting device for mounting and centering a known tool on a single punching machine, which is capable of achieving higher part machining accuracy than is currently available. It is an object of the present invention to provide a mounting device that enables punch products currently on the market to be used regardless of the manufacturer of the punch products while maintaining the sex.

[0006]

SUMMARY OF THE INVENTION The object is to provide a platform for supporting a metal sheet material, a turret-shaped head operably mounted above the platform, and an associated hammer provided on the head. In a mounting device for mounting and centering a tool on a single punching machine comprising a means, a vertical post is provided beside the hammer means and, in combination with the head, in a horizontal plane as well. A horizontal arm is rotatably movable, the free end of which is provided with at least one cylindrical seat having a sliding fit through seat 8a for punching, which arm interferes with the hammer means. The seat and associated punches housed therein are rotatable from a non-operating position to a position where they are centered between their own axis and the axis of the hammer means, and the elastic compression means is Provided between the comma means of the cylindrical seat, it is achieved by the mounting apparatus characterized by being adapted to automatically pull by a single reaction the punch and punching occurs from the metallic sheet material.

[0007]

According to the invention, the punch is mounted in a slide-fit through seat in a cylindrical seat at the free end of the arm. The arm is rotated horizontally around a vertical column to reach a centered (centered) position between the axis of the punch and cylindrical seat and the axis of the hammer means, once punching occurs. The elastic compression means provided between the hammer means and the cylindrical seat automatically withdraws the punch from the metal sheet material by reaction.

Another feature and advantage of the present invention is a preferred, but not exclusive, embodiment of a mounting device for mounting and centering known tools on a single punching machine. It will be clear from the description of the examples.

[0009]

1 and 2, reference numeral 1 indicates an entire mounting device for mounting and centering a known tool on a single punching machine, which punching machine supports a metal sheet material 3. A pedestal 2 and a turret-shaped head 4 operably mounted above the metal sheet material 3.

The head is provided with a single hammer or tool means 5. Furthermore, a vertical column 6 is assembled beside the head, and the vertical column 6 is connected to an arm 7 which rotates in a horizontal plane along a circular path so as to allow the arm to move.

The free end of the arm 7 is equipped with a cylindrical seat 8 provided with a through seat 8a, which is fitted with an unillustrated adapter element and then a punch 9 of a known type. Accommodate.

An elastic compression means 10 is provided between the hammer 5 and the cylindrical seat 8 so that the compression means 10 automatically withdraws the punch 9 from the metal sheet material 3 once punching occurs. It is distributed. The elastic compression means 10 is
When the punch 9 is wound around the punch 9 coaxially therewith and cooperates with the cap 12 at the upper position and the circular flange 13 at the lower position to perform punching once, the metal sheet material 3 is used to punch the punch 9.
Of at least one large helical spring arranged to pull out by reaction. The collar is combined with the cylindrical seat 8 via a plurality of elastic compression springs 14.

The working position of the arm 7 is horizontally arranged on the punching machine and operated by hydraulic pressure, and its core shaft 16a is defined tangentially to the side surface of the cylindrical seat 8 thereat. It is kept stable by an associated member 15 consisting of at least one cylinder 16 extending into the shaped recess 17.

Finally, the seat 18 and die 2 for accommodating the hammer 5
It should be emphasized that the 0 concaves 19 are made in a single boring process which makes them perfectly concentric.

The operation of the invention can be inferred intuitively from the above description. In the non-interfering position of the arm 7 shown in FIG. 1, the cylindrical seat 8 is ready to house a commercially available punch, which after insertion of an adapter element not shown in the drawing. It is inserted into the through seat 8a.

Once the punch is firmly fixed to the cylindrical seat 8, the arm 7 is rotated until the axes of the hammer 5 and the cylindrical seat 8 are perpendicular to each other (center). . In this arrangement, the axis of the concave 19 is also accurately centered with respect to the axes of the hammer 5 and the cylindrical seat 8 for the machining done to define the concave. In machining, a single machining process,
There is always a boring to create a seat 18 for accommodating the hammer 5 by sliding fit and the recess 19 itself. Once centering occurs, the cylinder 16 is actuated and its mandrel 16a projects therefrom to engage the recess 17 and hold the arm 7 stationary during the punching process.

Once the working process of the punching process accompanied by the compression of the large spring 11 is completed, the spring spontaneously expands to facilitate the extraction of the bunch 9 from the metal sheet material 3. The mandrel 16a is retracted, and the arm 7 can be rotated, if desired, so as not to interfere with the hammer 5. The punch 9 of the cylindrical seat 8 can then be replaced by another punch of a known type with a different cross section.

In fact, it has been observed that the invention described above achieves its intended purpose.

The present invention based on the above concept can be easily modified and modified within the scope of the concept of the invention. Thus, for example, the hydraulically actuated cylinder 16 can be replaced by a rotating pawl whose hook can be inserted exactly into said recess 17. Furthermore, all details may be replaced by other technically equivalent elements.

In practicing the present invention, the materials and methods used may be any according to the requirements without departing from the scope of the claims.

[0021]

Since the present invention has the above-mentioned structure, the punch products currently on the market can be manufactured while maintaining the possibility of achieving a higher part machining accuracy than that currently obtained.
It can be enabled regardless of the manufacturer.
