Description

  The present invention relates to a press die and a press apparatus used for performing predetermined processing on metal and other materials.

  2. Description of the Related Art Conventionally, a press mold and a press apparatus for performing predetermined processing on metal and other materials have a configuration as shown in FIG.

  FIG. 2 is a cross-sectional view of a main part of a conventional press die and press apparatus.

  In FIG. 2, 1 is a press machine bolster and 2 is a press machine ram. 3 is a die die holder fixed to the press bolster 1, 4 is a lower backing plate fixed to the die holder 3, and 5 is a die plate serving as a lower die fixed on the lower backing plate 4. In the die plate 5, a die tool portion 5a for performing predetermined processing on the metal and other materials 6 is configured as an integral or divided structure.

  7 is a die punch holder fixed to the press machine ram 2, 8 is an upper backing plate fixed to the punch holder 7, and 9 is a punch plate serving as an upper die fixed to the lower surface of the upper backing plate 8. Reference numeral 10 denotes a stripper plate which is held by a bush type stripper bolt composed of a flanged sleeve 11 and a bolt 12 while being suspended from an upper mold composed of a punch holder 7, an upper backing plate 8 and a punch plate 9. ing. This stripper plate holding method is an example, and other general holding methods are not explicitly described. The stripper plate 10 is pressed by a spring 14 pressed by a screw plug 13 in the punch holder 7 via a bolt 12 and a flanged sleeve 11.

  Reference numeral 15 denotes a punch for performing predetermined processing on the metal and other material 6 together with the die tool portion 5a for performing predetermined processing on the metal and other material 6. The punch 15 is held by the punch plate 9, and the stripper plate 10 has a stripper plate punch through hole 10a through which the punch 15 passes.

  For reference, FIG. 3 shows a cross-sectional view of the main part in a processing state in which the press machine ram 2 is lowered and the metal and other materials 6 are punched by the punch 15 and the die tool part 5a. 301 is an example of the punched material.

  The above contents are very general matters for those who are related to the press mold and the press apparatus, and it goes without saying that there are various other configurations of press molds and press machines.

For example, Patent Document 1 is known as prior art document information relating to this application.
Japanese Examined Patent Publication No. 7-16721

  However, in the configuration of the conventional press die and press device, the material residue 401 generated during processing and adhering to the side surface of the punch 15 is accumulated in the gap between the punch 15 and the through hole 10a for the stripper plate punch. In order to clean the material residue 401, there is a problem that the mold must be removed from the press machine and the stripper plate 10 must be removed from the upper mold.

  FIG. 4 shows an example of the accumulation state of the material residue 401.

  The present invention solves the above-described problem. The punch 15 is protruded from the stripper plate 10 by bending the spring 14 and raising the stripper plate 10 while the press die is mounted on the press machine. This makes it possible to clean the material residue 401 adhering to the side surface of the machine, dramatically simplifying the cleaning of the press mold in a short time, and realizing reduction in maintenance costs and improvement in productivity. It is intended.

  In order to achieve the above object, the present invention has the following configuration.

  According to the first aspect of the present invention, the die is attached to the press machine by mounting a stripper plate raising bolt for raising only the stripper plate also as a bolt for suspending the stripper plate on the upper die or as a separate item. It is possible to raise the stripper plate while it is mounted, and it is possible to clean the material residue adhering to the side of the punch without removing the mold from the press machine, so the cleaning of the press mold is dramatically It is possible to simplify the operation in a short time, and to obtain the effect of reducing the maintenance cost and improving the productivity.

  As described above, according to the present invention, it is possible to raise the stripper plate while the mold is mounted on the press machine, and the cleaning of the material residue adhering to the side surface of the punch can be performed without removing the mold from the press machine. Therefore, the cleaning of the press mold can be dramatically simplified in a short time, and the maintenance cost can be reduced and the productivity can be improved.

(Embodiment 1)
Hereinafter, the first aspect of the present invention will be described using the first embodiment.

  FIG. 1 is a cross-sectional view of a main part of a press die and a press apparatus according to Embodiment 1 of the present invention.

  In FIG. 1, reference numeral 112 denotes a special bolt that suspends the stripper plate 10 on the upper mold. The head of the special bolt 112 has a hexagon wrench hole and a tap. A stripper plate raising bolt 201 as a stripper plate raising member is attached to the head tap of the special bolt 112 through the through hole of the press machine ram 2, the through hole of the screw plug 13 and the inside of the spring 14. By raising the stripper plate raising bolt 201, the punch 15 is protruded from the stripper plate 10, and the material waste 401 adhering to the side surface of the punch 15 can be cleaned.

  FIG. 5 is a cross-sectional view of an essential part showing an embodiment of a mechanism that does not use the special bolt 112, and has a structure in which a long type stripper plate lifting bolt 501 is directly fixed to the stripper plate 10.

  Further, it goes without saying that there are various methods for raising the stripper plate raising bolt 201, but an example will be described with reference to FIG. FIG. 6 is a cross-sectional view of an essential part showing an example of the stripper plate lifting mechanism. The lifting plate 602 having a hole penetrating the stripper plate lifting bolt 201 is processed into the lifting screw 601 by rotating the lifting screw 601. The screw part is a mechanism for raising the ascending plate 602 via the threaded part processed into the ascending plate 602. The lowering is possible by rotating the ascending screw 601 in the reverse direction.

  In addition to this, it is needless to say that the lift mechanism may be a lever type method or many other lift mechanisms, and the stripper plate can be lowered to the original position after cleaning the mold. It is.

  As described above, according to the press die and the press device of the present invention, it is possible to raise the stripper plate while the die is mounted on the press machine, and to clean the material residue adhering to the side surface of the punch. Since it becomes possible without removing the die from the press machine, cleaning of the press die can be dramatically simplified in a short time, and the effect of reducing maintenance costs and improving productivity can be obtained. Is.

  The press mold and the press apparatus according to the present invention can lift the stripper plate while the mold is mounted on the press machine, and the mold is removed from the press machine by cleaning the material residue adhering to the side surface of the punch. Since it becomes possible without removing it, it has the effect of greatly simplifying the cleaning of press dies in a short time, reducing maintenance costs and improving productivity. It is useful as a press die and a press device used for processing.
