Lubricating oil circulating lubricating and cooling structure for ball head and ball bowl of high-speed press

Abstract

The invention discloses a circulating lubrication cooling structure for lubricating oil of a bulb spherical bowl of a high-speed press machine. The circulating lubrication cooling structure for the lubricating oil of the bulb spherical bowl of the high-speed press machine comprises a lubricating pump station (1), wherein the lubricating pump station is installed on one side of a press machine lower transverse beam (29), the lubricating pump station is connected with a lubricating oil inlet (6) of a sliding block cylinder body (3) through an oil inlet pipe (2) to carry out oil supply, the lubricating pump station is connected with an oil chamber in a press machine upper transverse beam (28) through an oil return pipe (13) to carry out oil return, a through oil hole (20) is formed inside a guide pillar threaded rod (8), an oil inlet (26) is formed in the center of the bottom of a lower spherical bowl (21), the through oil hole is communicated with the oil inlet, and a piston opening (19) is formed in the side wall of a hydraulic cushion piston (7). According to the circulating lubrication cooling structure for the lubricating oil of the bulb spherical bowl of the high-speed press machine, the lubricating pump station is independently installed, lubricating oil is supplied through pressure instead of the gravity, the lubricating oil is supplied from the interior of the guide pillar threaded rod from bottom to top instead of from top to bottom, the effect of the lubricating oil for cooling the bulb spherical bowl is good, and the lubricating oil can be recycled.

Description

technical field [0001] The invention relates to a lubricating oil circulation lubricating and cooling structure for a ball head ball bowl of a high-speed press, and belongs to the technical field of press parts. Background technique [0002] The structure of the ball head bowl and its associated parts of domestic high-speed presses, especially the closed single-point, double-point, and four-point presses, the structure of the ball head ball bowl and its associated parts on the high-speed press mainly realizes three functions: 1. It is the adjustment of the mold height of the slider; the second is the hydraulic overload protection and the elimination of the thread gap between the adjustment nut and the guide post screw; the third is the guide post screw drives the slider to reciprocate up and down for stamping. Due to the multi-function and complicated structure of the ball head ball bowl and its associated parts of the high-speed press, most of the ball head ball bowl struct...

AI Technical Summary

Problems solved by technology

Due to the multi-function and complicated structure of the ball head ball bowl and its associated parts of the high-speed press, most of the ball head ball bowl structures currently used are oil-immersed and lubricated, and the lubricating oil is stored in the oil chamber on the upper part of the press machine. , the lubricating oil flows down from the oil chamber by gravity, and then lubricates the ball head, ball bowl and other parts. This lubricating method cannot recycle the lubricating oil

[0003] Since the pressure of oil-immersed lubricating oil is close to zero, when the press works at high speed and heavy load, the relative movement speed of the ball head and the bowl is fast, and the gap between the contact surfaces is close to zero, so it is difficult for the lubricating oil to enter the contact surface, which is prone to ball joint Ball heating, rapid wear, burns and other problems will affect the running accuracy of the slider and cause the machine tool to fail to work normally
