Problems solved by technology

[0011] Therefore, after the punching process of the plate-shaped workpiece has passed, the up and down movement of the lifting ring may not be carried out smoothly.
Therefore, when the workpiece is punched at high speed, there is a problem that the following action of the die to the up and down movement of the ram sometimes lags behind.

Abstract

A punch die which is vertically movably mounted to a punch mounting hole (5) formed in a punch holder (3) of a punch press, wherein a punch body (41) which has a punch edge section (101) at the lower end thereof is vertically movably provided within a tubular punch guide (17) which is vertically movably mounted within the punch mounting hole (5), an elastic member (35) is provided between the punch guide (17) and a punch head (33) at the upper end of a punch driver (31) provided to the upper part of the punch body (41), a supported section (19) which is supported by a lifter spring (7) provided to the punch holder (3) is provided to the outer peripheral surface of the punch guide (7), a lubricating oil path (93U) which communicates with a lubricating oil supply path (83) formed in the punch body (41) is provided to the outer peripheral surface of the punch guide (17), and the lubricating oil path (93U) can be communicated with and interrupted from a lifter spring containing hole (9) which contains the lifter spring (7).

Description

technical field [0001] The present invention relates to a punching die and a lubricating oil supply method mounted on a punch such as a turret punch press, and more specifically relates to a method for receiving oil mist supplied from a press head mounted on a punch press that can move freely up and down. A die and a method of supplying lubricating oil that perform the function of lubricating between the inner peripheral surface of the punch mounting hole on the punching machine and the outer peripheral surface of the punch guide portion of the die. Background technique [0002] As for the die, the punch main body integrally having a punch blade at the lower end is mounted in a cylindrical punch guide so that it can move up and down, and the punch guide is supported on, for example, a turret punch press. on the upper turret. In addition, in a general configuration, a discharge spring is elastically provided between the punch top provided on the upper end of the punch driver...
