一般的である。2. Description of the Related Art Conventionally, a stationary plate disposed on an upper portion is supported by a plurality of columns erected from the periphery of a base mounted on a foundation, and a through hole slidable in the vertical direction through the columns. A press having a structure in which a reciprocating disc having a peripheral portion is provided between the immovable disc and the base, a thread is cut at an upper end of the support, and a nut is fastened to the screw to fix the prop and the immovable disc. In a molding apparatus, a method is generally used in which the nut is used as a double nut to prevent loosening of the nut.

い等の問題があった。However, in the case where the press forming apparatus becomes large and the diameter of the column exceeds 100 mm and a large nut is used, there is almost no general-purpose tool for sufficiently fastening the double nut. The re-tightening operation requires work at a high place above the press forming apparatus, and has problems such as poor workability.

つながる。[0004] For this reason, the nut often becomes loose due to repeated vibrations and the like during long-term use of the press forming apparatus. The slack of each nut of the plurality of pillars is not uniform, and therefore, the parallelism of the daylight (the horizontality of the reciprocating machine) is deviated. An upper mold of a molding die is usually attached to the lower surface of the reciprocating machine, and the unevenness of the horizontality of the reciprocating machine leads to a problem that the dimensional accuracy of a product to be compression molded is also disturbed.

る。A press forming apparatus according to the present invention (hereinafter, referred to as an apparatus according to the present invention) comprises a plurality of columns which stand upright from a peripheral edge of a base on which a stationary plate arranged on the base is installed. A reciprocating plate having a through hole penetrating the column and slidable in the vertical direction at the periphery is provided in the middle between the stationary platen and the base, and the upper end of the column is threaded, In a press forming apparatus having a structure in which a support and a stationary plate are fixed by fastening a nut to a screw, loosening of the nut is prevented by a hydraulic cylinder provided on an upper portion of the stationary plate. .

A reciprocating disc having a movable through hole on the periphery is provided between the immovable disc and the base, a thread is cut at the upper end of the support, and the post and the immovable disc are fixed by fastening a nut to the screw. In the press forming apparatus having the above configuration, the nut is prevented from being loosened by the hydraulic cylinder provided on the upper part of the stationary plate, so that the parallelism of the daylight does not change even after long-term use.
