Embodiment Construction

[0042] An embodiment of the present invention will be described with reference to the accompanying drawings. figure 1 is a front view of the press machine according to this embodiment, figure 2 is a top view of the stamping machine, image 3 It is a side view of the press machine. This press machine is a plate bender. On the front side of the main body frame 1, there are provided a table 3 as a fixed support member that supports a lower die 2 that is a die on a fixed side, and an upper die 4 that supports a die on a movable side. The pressure head (ram) 5 as a movable supporting part. The workbench 3 is fixed in position with respect to the main body frame 1, and the indenter 5 passes through the guide mechanism 26 ( figure 2 , image 3 ) can be lifted. Lower mold 2 is to have the concave portion 2a ( image 3 ) is an integrated mold that is longer in the left and right directions. The upper die 4 has an end portion 4a ( image 3 ), which is the mold with the same l...

Abstract

The invention provides a flexibility rectification adjusting device of a punching machine, which can properly keep the position relationship between an upper mold and a lower mold during a punching process and ensure enough tolerance relative to the pressurization process. The flexibility rectification adjusting device (6) adjusts the height of the upper mold or the lower mold, for example the upper mold (4A). The flexibility rectification adjusting device (6) is fixed on a support part (5) of a support mold through a mold fixing mechanism (7) in a way to have the height adjustable. Intermediate wedge-shaped parts (8) are equipped on the horizontal direction between the mold (4A) and the support part (5). The intermediate wedge-shaped part face contacting with the mold (4A) is inclined along the front-to-back direction. The intermediate wedge-shaped parts each further have a cylindrical face (8b) recessed on the projecting side of the mold (4A). The intermediate wedge-shaped part (8) can freely slide along the front-to-back direction of the mold (4A) and the circumferential direction of the cylindrical face. A vertical position change mechanism (21) is equipped to make the vertical position of the intermediate wedge-shaped part (8) change.

Description

technical field [0001] The present invention relates to a deflection compensation adjustment device for adjusting the heights of upper and lower dies in press machines such as a plate bender so that the upper die and the lower die are in an appropriate height relationship for press processing. Background technique [0002] In a plate bender, lifting and lowering of a movable support member that supports the movable side die among an upper die and a lower die is generally performed by elevating mechanisms provided on left and right sides of the movable support member. [0003] In this case, since the left and right central portions of the movable support member bend toward the opposite side of the pressurizing direction during pressurization, the height relationship between the upper mold and the lower mold may become inappropriate. In order to prevent such a situation, the mold on the movable side is composed of a plurality of mold divisions divided in the left-right directi...
