AI Technical Summary

Technical Problem

Conventional shear devices with two-cylinder configurations have an increased overall height, making it difficult to position a shear knife spray device near the shear blade for effective lubrication, and existing solutions fail to reliably apply lubricating liquid to the shear blades.

Method used

A shear knife spray device that moves a spray nozzle from a standby position to an application position when the shear blades are at their uppermost position, using an actuator mounted on the shear guide or fixed frame, allowing lubrication near the shear blade without increasing the device's overall height.

Benefits of technology

Enables effective lubrication of shear blades in a two-cylinder shear device by positioning the spray nozzle correctly, avoiding interference and maintaining the device's compact height without affecting the cycle time.

Abstract

To provide a shear knife spray device that can apply a lubricating liquid to a shear blade from the vicinity of the shear blade, even in the case of a two-cylinder shear device that restricts the overall height of the shear device.SOLUTION: The object of the present invention is achieved by a shear knife spray device 50 of a shear device of an extrusion press apparatus in which a cylinder rod of each of shear cylinders 35 is fixed below a shear slide 33 so as to enable an overall height of the extrusion press apparatus to be restricted, in a manner that when a shear blade 34 is at its uppermost position, a spray nozzle 51 is moved from a standby position to an application position so as to be able to apply lubricating liquid to the shear blade 34.SELECTED DRAWING: Figure 4
