Abstract
Description
The present invention relates to a blanking die for shim making, and more particularly, to a blanking die for core manufacture in which a core including a core in a die holder and a core in which a punch through hole is formed in a stripper plate can be partially replaced will be.
Conventional blanking mold units for shim manufacturing are difficult to recycle, and when the products are discontinued, they are discarded and dispose of them as scrap iron, resulting in a great economic loss. In addition, since the entire press mold is required to be produced whenever necessary, there is a disadvantage that it is difficult to produce the press mold quickly. In addition, it is a fact that the proportion of mold cost among product cost can not be neglected in small quantity production in the small quantity production trend of various kinds.
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a blanking die for shim manufacturing which can produce various shims while replacing only a first core having a punch through hole in a stripper plate and a second core including a die in a die holder .
Another object of the present invention is to provide a method of manufacturing a shim capable of producing various types of shim using a single first core, in which a first core having a punch through hole, which can be utilized commonly for a plurality of punches, Thereby providing a blanking mold.
Another technical problem to be solved by the present invention is to provide a core for producing a core which can be manufactured by replacing only a first core and / or a second core for a new core, To provide a mold.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not intended to limit the invention to the precise forms disclosed. Other objects, which will be apparent to those skilled in the art, It will be possible.
According to an aspect of the present invention, there is provided a blanking metallic mold for manufacturing a shim, comprising: a punch holder to which a blanking punch is fixed; A stripper plate on which a first core having a punch through hole through which a blanking punch fixed to the punch holder is formed is attached and detached; And a die holder in which a second core including a blanking die for cutting the plate material in cooperation with the blanking punch fixed to the punch holder is detachably mounted.
The punch through hole includes: a first blanking punch; And a common through hole of a second blanking punch having a common portion and a dedicated portion with the first blanking punch. At this time, the punch through hole passes through the first blanking punch when the first blanking punch is fixed to the punch holder, and when the second blanking punch is fixed to the punch holder, A first region through which the common portion with the first blanking punch penetrates; And a second region through which the dedicated portion of the second blanking punch penetrates when the second blanking punch is fixed to the punch holder.
The punch through hole may include a third region through which the third blanking punch penetrates when the third blanking punch is fixed to the punch holder; And a fourth region through which the fourth blanking punch penetrates when the fourth blanking punch is fixed to the punch holder. In this case, the punch through hole may be a common through hole of the third blanking punch and the fourth blanking punch in which a part of the third area and a part of the fourth area overlap.
In addition, the punch through-hole may include a fifth region through which the fifth blanking punch penetrates when the fifth blanking punch is fixed to the punch holder; And a sixth region through which the sixth blanking punch penetrates when the sixth blanking punch is fixed to the punch holder. In this case, the fifth region and the sixth region may be a common through hole of the fifth blanking punch and the sixth blanking punch, which do not overlap each other.
The blanking mold for shim manufacturing according to the present invention can produce various shims while replacing only a first core having a punch through hole in a stripper plate and a second core containing a die in a die holder.
The blanking mold for shim manufacturing according to the present invention has an advantage that various kinds of shims can be produced by using one first core when a first core having punch through holes that can be utilized commonly for a plurality of punches is mounted have.
Therefore, according to the blanking mold for shim manufacturing according to the present invention, it is possible to produce a variety of shims as compared with a conventional mold in which a stripper plate or a die holder is to be replaced entirely, at the same time, There are advantages.
Furthermore, since the blanking mold for shim manufacturing according to the present invention requires only the first core and / or the second core to be manufactured and replaced for a new shim, it is possible to shorten the mold making period and reduce the cost.
