Internal storage and distribution pipe structure for oil inlet pipe and oil outlet pipe of oil cylinder of column type tablet machine

Abstract

An internal storage and distribution pipe structure for an oil inlet pipe and an oil outlet pipe of an oil cylinder of a column type tablet machine comprises an upper fixed plate, a lower fixed plate, guide stand columns, an oil cylinder, high-pressure oil pipes and a hydraulic station. The two ends of each guide stand column are fixed to the upper fixed plate and the lower fixed plate respectively. The two high-pressure oil pipes on the oil cylinder are connected with the hydraulic station in a sealed mode. At least one guide stand column is of a hollow pipe structure. The high-pressure oil pipes penetrate through the hollow guide stand columns to be connected with the hydraulic station in a sealed mode. The two high-pressure oil pipes of the oil cylinder are changed to be distributed in an internal storage mode from the exposed mode. The attractiveness of the whole tablet machine is improved, the arrangement space of dies and other parts of the table machine is enlarged, and hurting accidents of high-pressure oil leakage generated when the high-pressure oil pipes are broken are eliminated. The internal storage and distribution pipe structure can ideally overcome all the defects, caused by the exposed arrangement of the high-pressure oil pipes of the hydraulic cylinder, of an existing tablet machine.

Description

Technical field: [0001] The invention relates to a column type hydraulic forming tablet press, in particular to a connecting pipeline of a hydraulic oil cylinder in a four column type hydraulic forming tablet press. Background technique: [0002] In the existing vertical four-column hydroforming tablet press, according to different tablet pressing requirements, a hydraulic oil cylinder is installed on the top of the tablet press, and some hydraulic cylinders need to be installed at the bottom. All hydraulic cylinders must be connected to the hydraulic station through high-pressure oil pipes. At present, all high-pressure oil pipes are exposed pipes, which not only affect the overall aesthetics of the tablet press, but also affect the tablet press. The layout of the mold and other parts of the tablet press reduces the operating space between the four columns of the tablet press, and the length of the high-pressure oil pipe is relatively large. More importantly, this exposed o...

[0002] In the existing vertical four-column hydroforming tablet press, according to different tablet pressing requirements, a hydraulic oil cylinder is installed on the top of the tablet press, and some hydraulic cylinders need to be installed at the bottom. All hydraulic cylinders must be connected to the hydraulic station through high-pressure oil pipes. At present, all high-pressure oil pipes are exposed pipes, which not only affect the overall aesthetics of the tablet press, but also affect the tablet press. The layout of the mold and other parts of the tablet press reduces the operating space between the four columns of the tablet press, and the length of the high-pressure oil pipe is relatively large. More importantly, this exposed oil pipe distribution structure will also cause accidents on the high-pressure oil pipe. Damaged, damaged high-pressure oil pipes will cause high-pressure oil leakage, and high-pressure oil will spray, which will cause serious accidents that hurt people
