[0001] SEPARATING APPARATUS FOR MATERIALS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molding and demolding apparatus for a sequential machining material, and more particularly, to a molding and demolding apparatus for a sequential machining material, which enables a sequential machining material to be smoothly deformed from a lower portion to an upper portion.

Generally, forging is a molding method in which a material such as iron or non-ferrous metal is pressed to give plastic deformation. The forging operation for compressing the workpiece is performed by a press machine (hereinafter referred to as "press ") including upper and lower dies.

Further, in the case of conventionally performing the plastic working of a material through forging, there is known a single forming method in which a single material is compressed to form a forged product, and furthermore, a long plate material is put into a progressive press, Thereby forming a forged product.

Hereinafter, an example of a conventional sequential forming method will be described as follows. A "sequential feed processing apparatus" (hereinafter referred to as "conventional sequential feed processing apparatus") of Korean Patent Registration No. 0417939 is as follows.

Therefore, the conventional sequential feed processing device is a process for sequentially forming the forged workpieces to form the forged workpieces, wherein a plurality of the processing units are made to correspond to a plurality of processing steps (hereinafter, referred to as "workpieces" Wherein the main body comprises a substrate, a support plate provided so as to be spaced apart from the substrate by a predetermined distance, and a support plate provided between the substrate and the support plate, And a slider formed to be movable in a direction orthogonal to the support plate, and driving means for driving the slider. Further, the machining unit is formed as a machining unit, and the movement of the slider is controlled so that machining can be continuously performed.

However, when a long material is forged by using the conventional sequential feed processing apparatus, the material to be formed is often not deformed to the upper portion while being inserted into the forming portion formed in the lower mold .

Therefore, when a long material is forged by using a conventional sequential feed processing apparatus, the material is not deformed from the inside of the lower mold, so that the press apparatus is frequently stopped.
