Abstract
The invention discloses a diamond press which comprises a cylinder body, a piston, a lower beam, a column, an upper beam and an anvil, wherein, the cylinder body and the lower beam are of an integral casting, the cylinder body is provided with a cylindrical forged bush which is immobilized in the cylinder body on the inner side, and the piston moves in the cylinder body with the bush on the inner side. By arranging the forged bush on the inner side of the cylinder body, the invention solves the sealing problem of the forged cylinder body, thereby enabling the cylinder body and the lower beam to be combined into a whole, greatly reducing the volume of the diamond press, and reducing the cost of the diamond press.
Description
Technical field
The present invention relates to a kind of press, the employed diamond press of especially a kind of making diamond.
Background technology
Adamantine extreme hardness has general application in industry.For example will use diamond as cutter head on the lathe tool of lathe, part is processed.But natural diamond is very rare, and price is very expensive, can't generally be used.And diamond is cheap, can satisfy industrial requirement.
Diamond grain growth under extremely high pressure (5500MPa) and excessive temperature (1500 ℃) forms.Existing diamond synthesis mode can be divided into two kinds of technologies of cubic apparatus and two tops, produces the diamond overwhelming majority at present and also is to use cubic apparatus technology.Cubic apparatus technology is exerted pressure and is generated diamond from six direction exactly, and the diamond taste that this technology is made is lower.And two top technology is from both direction up and down diamond to be exerted pressure, and diamond is grown in special mould.The diamond particles of two top explained hereafter is big, taste is high.The diamond press of the required use of two top technology and mould thereof all are to work under limiting condition, therefore diamond press are had very high requirement.In order to reach so high pressure, the cylinder body of existing diamond press all is to make with forging, installs with underbeam then, because underbeam needs the requirement on the supporting structure, so underbeam is to make with foundry goods.And foundry goods is because the feature of itself material structure makes the sealing of foundry goods can not satisfy the requirement of doing cylinder body.So the volume of existing diamond press is very huge all, makes cost of manufacture also than higher.
Summary of the invention
Technical problem to be solved by this invention provides a kind of diamond press, can have simple light and handy structure, reduces the cost of diamond press.
For solving the problems of the technologies described above, technical scheme of the present invention is, comprise cylinder body, piston, underbeam, column, upper beam and top hammer, described cylinder body and underbeam are the foundry goods of one, described cylinder body inboard is provided with the forging lining of tubular, the forging lining of described tubular maintains static in described cylinder body, and described piston moves in described installed inside has the cylinder body of lining.
The present invention has solved the sealing problem of foundry goods cylinder body by in the cylinder body inboard forging lining being set, and makes cylinder body and underbeam be integrated, and has reduced the volume of diamond press greatly, and has reduced the cost of diamond press.
Description of drawings
The present invention is further detailed explanation below in conjunction with drawings and Examples:
Fig. 1 is the overall structure schematic diagram of diamond press of the present invention;
Fig. 2 is the side view of the cylinder body of diamond press of the present invention;
Fig. 3 is for being equally divided into the structural representation of the annular key of multistage among the present invention.
Reference numeral is among the figure, 1. cylinder body; 2. column; 3. put the beams in place; 4. the top is hammered into shape; 5. mould; 6. piston; 7. lining; 8. annular key; 9. lid.
The specific embodiment
Diamond press of the present invention can be referring to illustrated in figures 1 and 2, and primary structure comprises the underbeam of column, column bottom and the upper beam on column top, and described underbeam and upper beam combine three root posts, thereby it is firm to make whole diamond press to stablize.The underbeam below of traditional diamond press also is provided with a cylinder body, is provided with piston in the cylinder body, and described piston actuated top hammer compression mould is made diamond.And among the present invention, described cylinder body and underbeam are the foundry goods of one, and described cylinder body 1 inboard is provided with the forging lining 7 of tubular, and the forging lining 7 of described tubular maintains static in described cylinder body, and described piston 6 moves in described installed inside has the cylinder body of lining 7.
Why cylinder body in the existing diamond press adopts the forging structure, just because the material sealing of foundry goods is poor, can not satisfy the requirement of pistons work.And the present invention is provided with the forging lining 7 of tubular in the cylinder body inboard of foundry goods, described piston 6 moves in described lining 7, drive top hammer 4 compression moulds 5 and make diamond, solved the sealing problem of pistons work, therefore can simplify the structure of underbeam and cylinder body greatly, make underbeam and cylinder body can adopt the structure of compact foundry goods one, saved cost, also reduced the volume of diamond press.
Described lining 7 is an interference fit with the fit system of described cylinder body 1 inboard.Because it is very big to make the needed pressure of diamond, described lining 7 and described cylinder body 1 adopt the mode of interference fit, can prevent slip each other so that lining 7 can be fixed more closely with described cylinder body 1 during work.
The inboard position that is positioned at described lining upper limb, described cylinder body upper end is provided with annular recess, and an annular key 8 embeds described annular recess, described lining is limited in the described cylinder body and can't upwards skids off.
The upper end of described cylinder body also is provided with lid, and described lid fastens described annular key from the top.
Described annular key is equally divided into multistage by circumference, referring to shown in Figure 3.The annular key that is equally divided into multistage is more convenient for installing.
In sum, the present invention has solved the sealing problem of foundry goods cylinder body by in the cylinder body inboard forging lining being set, and makes cylinder body and underbeam be integrated, and has reduced the volume of diamond press greatly, and has reduced the cost of diamond press.And this structure is easy to make and install, and is very easy to realize.
