Description

Thin plate molding device

According to the present invention, in forming a thin material such as a printed board using a pressure of a fluid, the material is molded into a thin plate shape required by the pressure pressurized by a mold and lifted for forming the product. It relates to a sheet metal forming machine having a lifting means to move the movable member horizontally through one cylinder.

In general, in manufacturing thin plates used for printed boards of electronic products or thin plate parts of machines by using materials in the form of plates, the molds which are divided into upper and lower parts are formed by lifting or lowering molds to be installed or separated. In the case of thin plates having a relatively thin thickness and a complicated structure, the latter was formed by supplying a fluid fluid between the upper and lower molds and supplying a separate fluid between the upper and lower molds and by pressure on the weaning body. It is widely used.

However, in the related art, the movable member, which is formed on the mold mounted on the fixed member and mounted on the mounting base, is configured to reciprocate by a hydraulic cylinder. However, when the movable member is molded on the mold to close the mold, the movable member Pressing force to the upper side is weak, and when a constant pressure is applied for forming the material in the state of closing the mold, there is a problem that the supporting force for supporting the movable member is weak and the movable member is pushed to the lower side and the center of the movable member Since the hydraulic cylinder was operated to raise and lower the movable member, it was difficult to maintain the overall horizontal state of the movable member, and there was a closed end where both sides of the movable member were sag.

In addition, conventionally, since water is mainly used as a medium for pressurizing and pressing a material, the molding of the product may not be uniform due to the volume and density of the water, and the thickness of the material to be formed may be nonuniform. There was a problem such as deterioration.

The present invention has been made in view of the above-mentioned conventional problems, and in forming a thin plate material used as a printed circuit board such as a thin machine part or an electronic product, the material is placed so as to be molded with the mold of the fixing member. Elevating means is provided below both sides of the movable member on which the stand is mounted, and the elevating means is driven by the elevating cylinder, thereby allowing the movable member to form a material while the pressing action of the horizontal state is performed by the elevating means. The purpose of the present invention is to provide a sheet forming machine that can enhance the formability of the product by reinforcing the compressive force and the supporting force to push the upper parts of the members, and by replacing the medium for pressing the material with oil rather than water. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and embodiments.
