Oil return device for slide block of press machine

Abstract

The invention belongs to the field of press machines, and particularly discloses a press machine sliding block oil return device. The press machine sliding block oil return device comprises a stand column guide rail, an oil collection groove, an oil return pipe and an oil collection pipe. The stand column guide rail is arranged on one side of a sliding block and used for the sliding block reciprocating sliding up and down. The oil collection groove is formed in the stand column guide rail. The oil return pipe is arranged between the sliding block and the oil collection groove, one end of the oil return pipe is fixedly connected with the sliding block, and the other end of the oil return pipe extends into the oil collection groove and can carry out reciprocating moving up and down relativeto the oil collection groove. The oil collection pipe is arranged at the lower portion of the oil collection groove, one end of the oil collection pipe fixedly communicates with the oil collection groove, and the other end of the oil collection pipe is fixedly connected the stand column guide rail. The oil collection groove is formed in the stand column guide rail, the sliding block is connected with the oil collection groove through the oil return pipe, the oil collection pipe connected with an oil tank is directly arranged on the lower portion of the oil collection groove, wherein the oil collection groove is used for conveying oil return into a three-dimensional guide rail for lubrication of the sliding block reciprocating sliding up and down, and then the real-time recycling of oil leakage is realized.

Description

technical field [0001] The invention belongs to the field of presses, in particular to an oil return device for a slide block of a press. Background technique [0002] At present, the stamping equipment for automobile outer panels generally adopts a frame press. After the upper die is installed on the slider, the slider moves up and down along the column guide rails arranged at the four corners of the slider; the lubrication on the column rails The oil often overflows, and the slider overload protection system also often overflows the oil, resulting in serious oil pollution inside the slider. [0003] The solution in the prior art is to set an oil sump at the lower position of the lower plane of the slide block, set a valve at the bottom of the oil sump, and open the valve regularly to get rid of oil dirt. [0004] The solution measures in the prior art are simple in structure, and the oil leakage is concentrated in the oil collection tank during application, and oil dirt p...
