Abstract
The utility model relates to a self-centering closed-type hot-pressing steel mould, which belongs to the technical field of a processing device of a cutting implement. The facade of the mould is orderly provided with a reference surface, a sintering containing cavity and a sealing surface from the inner part to the outer part; the sintering containing cavity is lower than the reference surface; the sealing surface is higher than the reference surface. The back surface of the mould has the same structure with the facade of the mould, and the pattern of the back surface of the mould is staggered. The outer margin of the mould is provided with an axial positioning slot. The utility model is used for processing a saw blade; a closed sintering containing cavity can be formed at the time of high-temperature pressurization, and thus the utility model limits the increase of the outer diameter of the saw blade, improves the density of a fetal body and ensures the service performance of the saw blade. A central shaft is not used when the utility model is putted into a sintering furnace in a stacking mode; the utility model can play the function of self centering, avoiding that at the time of pressurization, the mould is difficult to unload because the central shaft is bent by force. The outer margin of the mould is provided with the axial positioning slot, ensuring that patterns at both sides of the saw blade are not displaced and thus the appearance of the saw blade is not affected.
Description
Technical field
The utility model belongs to cutting tool processing unit (plant) technical field, particularly a kind of closed hot pressing steel mould with assigning center.
Background technology
The density of small saw blade carcass directly influences it to durability of diamond, thereby influences cutting efficiency and service life.The small saw blade manufacturing process has two kinds, and a kind of is to cold pressing-free sintering, and another kind is to cold pressing-hot pressed sintering, for a kind of technology in back, can make the higher saw blade of class, satisfies the demand in market.What hot pressed sintering used at present is ordinary hot compressed steel mould, and the inner liquid phase that can produce of carcass flows in the sintering process, begins pressurization when sintering temperature reaches, and the saw blade external diameter causes carcass density low excessively because of stretching out without limits.It is that to add steel bushing restriction saw blade at whole string steel mold cylindrical outer through increasing that a kind of method is arranged, but because the different meetings with the steel mold material of steel bushing cause the mould unloading difficulty because of expansion coefficient difference.
The utility model content
The utility model purpose is to provide a kind of closed hot pressing steel mould with assigning center.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: closed hot pressing steel mould with assigning center, die face are followed successively by datum level, sintering cavity volume, sealing surface from inside to outside, and the sintering cavity volume is lower than datum level, and sealing surface is higher than datum level.
The mould back side but decorative pattern identical with Facad structure staggers.
The mould outer rim is provided with the axial location groove.
The utility model can be processed with 3Cr2W8V steel (being commonly called as oxida-tion-resistant steel), different datum level and the sealing surfaces of saw blade design according to different size, when hot pressing, guarantee the uniformity of sintering cavity volume and saw blade carcass volume, thereby make the saw blade carcass reach corresponding density, have the good mechanical performance.Utilize the utility model to carry out in the small saw blade process,, can form sealing sintering cavity volume during high-temperature pressurizing, increase, improved the density of carcass, guaranteed the serviceability of saw blade thereby limited the saw blade external diameter because sealing surface is higher than datum level.Simultaneously, stacked when putting into sintering furnace without central shaft, can play the self centering effect, thereby the stressed bending of central shaft is difficult to mould unloading when avoiding pressurizeing; The mould outer rim is provided with the axial location groove, guarantees that the decorative pattern of saw blade both sides does not misplace, and does not influence the saw blade outward appearance.

Fig. 3 is the partial enlarged drawing of Fig. 2.
The specific embodiment
Closed hot pressing steel mould with assigning center, die face are followed successively by datum level 1, sintering cavity volume 2, sealing surface 3 from inside to outside, and sintering cavity volume 2 is lower than datum level 1, and sealing surface 3 is higher than datum level 1.The mould back side is identical with Facad structure but decorative pattern staggers (same prior art), and 5 is the decorative pattern position.The mould outer rim is provided with axial location groove 4.
Claims (3)
1, closed hot pressing steel mould with assigning center, die face are followed successively by datum level, sintering cavity volume, sealing surface from inside to outside, and the sintering cavity volume is lower than datum level, it is characterized in that, sealing surface is higher than datum level.
2, mould as claimed in claim 1 is characterized in that, the mould back side but decorative pattern identical with Facad structure staggers.
3, mould as claimed in claim 1 or 2 is characterized in that, the mould outer rim is provided with the axial location groove.
