Abstract

PURPOSE:To clamp safely and surely a die plate without mutual interference in die plate clamping of a press by energizing axially the clamping head at the top end of a clamping rod which is oscillated by the pressure fluid. CONSTITUTION:A clamping arm 5 supported by means of a fulcrum pin 4 to a body 3 of a slide 2 descends to support the die plate 12 as a piston 8 is energized by a spring 11 so as to rise when the pressure of the pressure fluid of an air feed port 9 is released. The oil pressure from an oil feed port 21 acts on the upper cylinder chamber 16 of a piston 15 via an oil line 19 and rises the clamping head 17, thus clamping the plate 12 to the slide 12. The operation is reversed to unclamp the die plate. The above-mentioned die clamp 1 clamps and unclamps safely and surely the plate 12 without interference.

Since the lJ center is at the lower end of the piston and the center of oscillation moves as the piston moves up and down, the structure that gives oscillation to the clamp rod naturally becomes double current, and the height of the sill provided on the top of the stay of the press is high. However, there were drawbacks such as the need to select a mechanical knock located on the stay and install it in a position that would not cause turbulence.

[I1 Means for Solving the Problems and 孝用J The present invention eliminates these drawbacks, eliminates the movement of the pivoting center of the clamp rod, ensures the pivoting action, and improves the height of the top surface of the stay of the press. In order to make the installation more compact by lowering the pressure, a main body with a fulcrum pin of the clamp rod and a small air ring for swinging the clamp rod is installed on the top of the stay of the press. A sill-type clamp head is installed in the section that clamps using hydraulic pressure and unclamps using a spring.
-/It is supplied from the fulcrum bottle part through the passage in the door. Therefore, the external shape of the main body equipped with the fulcrum bottle etc. is miniaturized, and there is no interference with the mechanical knockout provided on the stay of the press, so there are no restrictions on the mounting position.
In addition, since the position of the fulcrum bottle is fixed, clamp pro 7
The lock swings reliably, and the clamp is strong because it is hydraulically operated.

The above explanation is about the upper mold clamper, but the same applies when fixing the lower mold to the bolster. oscillation is certain. Since the swinging piston is small and has a small stroke, the main body attached to the top of the stay is small and there is no interference with the mechanical knockout installed on the stay, so there are no restrictions on the mounting position of the upper type clamper. Since a clamping silling device is provided separately, the clamping operation is simple, and since hydraulic pressure is used, the clamping is strong. The practical effects and benefits are great.
