Abstract

The invention relates to a cold pressing device, in particular to a cold pressing device for powder. The cold pressing device for the powder comprises a press beam, anti-pulling columns, a cold pressing cylinder, a hydraulic case, upper press rods, lower press rods, a hydraulic-oil control port, a hydraulic ejector and a retaining plate. The cold pressing device is characterized in that the retaining plate is attached to the inner side of the cold pressing cylinder and is fixed with the cold pressing cylinder through a screw, three cold pressing holes are formed in one section of the cold pressing cylinder, the lower press rods and the upper press rods are respectively vertically put into the holes, and powder in need of cold pressing fills positions between the upper press rods and the lower press rods. By the cold pressing device, a plurality of groups of powder can be subjected to cold pressing by the same technology simultaneously, so that time for processing the powder by the same technology is greatly shortened.

Description

A kind of powder cold press device
Technical field
The present invention relates to a kind of cold press device, is a kind of powder cold press device specifically.
Background technology
The bulky powder that particle forms at room temperature can be pressed into the base substrate with definite shape, size, intensity, density by cold press device under certain pressure and apparatus, generally has a wide range of applications in producing at powder metallurgy, ceramic industry, tablet.Once can only to cold pressing when colding pressing with general cold press device one group of powder, and sometimes need several groups of different powder to adopt identical technological parameter to cold pressing when being contrast experiment, this adds the work of a lot of repeatability just to cold presswork person, causes the waste of manpower and materials.
Summary of the invention
In order to effectively solve above-mentioned puzzlement, the invention provides a kind of powder cold press device, this device once can be colded pressing with identical technique and be organized powder more, substantially reduces with the time of same process processing many groups powder.
The technical scheme that the present invention adopts for its technical problem of solution is: a kind of powder cold press device, comprises pressure beam, tensile resistance column, cylinder of colding pressing, hydraulic pressure cabinet, upperpush rod, down-pressed pole, hydraulic oil control mouth, hydraulic top, block plate.It is characterized in that: described block plate is fitted to the inner side of cylinder of colding pressing and is fixed together by screw and cylinder of colding pressing, one section of cylinder of colding pressing has three holes of colding pressing, down-pressed pole, upperpush rod are vertically put in three holes respectively, and what fill between upper down-pressed pole is the powder needing to cold pressing.
Described block plate has oil through, and hydraulic oil can produce pressure by oil through to down-pressed pole, and can stop again down-pressed pole because gravity falls cylinder bottom of colding pressing.
Described hydraulic top is that the mechanical energy produced by the hydraulic pump being arranged in hydraulic pressure cabinet promotes, and hydraulic top upper end is provided with sealing device, can prevent hydraulic oil from flowing out from hydraulic top and the gap of colding pressing between cylinder when hydraulic top upwardly hydraulic oil.
Described pushing cylinder upper end scribbles time special material can prevent from colding pressing and sintered powder adhesion, and lower end is provided with sealing device, can prevent the hydraulic oil of colding pressing in cylinder from entering powder and to cold pressing hole.
Described cylinder upper end of colding pressing has three cold sub-holes, and be used for installing down-pressed pole and powder, lower end has hydraulic jack, and side is provided with hydraulic oil controls mouth, is used for adding or hydraulic oil in exudate compressing cylinder.
The invention has the beneficial effects as follows: its simple structure, rationally, once can cold pressing with identical technique and organize powder more, substantially reduce with the same process processing time organizing powder more, contribute to boosting productivity.

Detailed description of the invention
A kind of powder cold press device, comprises pressure beam, tensile resistance column, cylinder of colding pressing, hydraulic pressure cabinet, upperpush rod, down-pressed pole, hydraulic oil control mouth, hydraulic top, block plate.It is characterized in that: described block plate is fitted to the inner side of cylinder of colding pressing and is fixed together by screw and cylinder of colding pressing, one section of cylinder of colding pressing has three holes of colding pressing, down-pressed pole, upperpush rod are vertically put in three holes respectively, and what fill between upper down-pressed pole is the powder needing to cold pressing.
Described block plate has oil through, and hydraulic oil can produce pressure by oil through to down-pressed pole, and can stop again down-pressed pole because gravity falls cylinder bottom of colding pressing.
Described hydraulic top is that the mechanical energy produced by the hydraulic pump being arranged in hydraulic pressure cabinet promotes, and hydraulic top upper end is provided with sealing device, can prevent hydraulic oil from flowing out from hydraulic top and the gap of colding pressing between cylinder when hydraulic top upwardly hydraulic oil.
Described down-pressed pole upper end scribbles time special material can prevent from colding pressing and sintered powder adhesion, and lower end is provided with sealing device, can prevent the hydraulic oil of colding pressing in cylinder from entering powder and to cold pressing hole.
Described cylinder upper end of colding pressing has three holes of colding pressing, and be used for installing down-pressed pole and powder, lower end has hydraulic jack, and side is provided with hydraulic oil controls mouth, is used for adding or hydraulic oil in exudate compressing cylinder.
During use, the powder of colding pressing will be needed to be put in three hydraulic pressure holes, hydraulic coupling and the hydraulic pressure time of opening hydraulic pump switch setting needs just can start working.
