Abstract
The utility model relates to a moulding die sleeve and use mould of this die sleeve for superhard grinding wheel. Moulding die sleeve includes the die sleeve main part of pipe box form for the superhard grinding wheel, and the internal face of die sleeve main part is the inner cylinder face, the outer peripheral face is the outer face of cylinder, and stingy groove has been offered to the symmetry in the both ends periphery of die sleeve main part, and the stingy groove of each end of die sleeve main part is the annular or at circumference interval distribution. When the damage appeared in the inner wall of die sleeve one end, the back was extracted with the die sleeve in the stingy groove of accessible from the die holder, upside down use the die sleeve, and the die sleeve inner wall after reversing is unmarred complete inner wall to avoid when the one end inner wall of die sleeve takes place the damage, need carry out whole inner walls of die sleeve the problem of repairing, but made the both ends looks trans -substitution of die sleeve, improved the utilization ratio of die sleeve, lengthened the restoration cycle of die sleeve, reduced the manufacturing cost of emery wheel.
Description
Technical field
This utility model is related to a kind of hard grinding wheel forming die sleeve and the mould using the die sleeve.
Background technology
At present, the production of hard grinding wheel is prepared and carried out in a mold, i.e., be first put into abrasive material in a mold, treats that abrasive material spreads out
After flat, fiber mat is put on abrasive material, then abrasive material in mould is heated and extruded, abrasive material is pressed in a mold
Finished grinding wheel.In the process, it is the compressing precision of guarantee emery wheel, the die sleeve inner wall smooth of mould need to be kept, also just needs
Often mould to be unloaded from pipeline, polishing finishing is carried out to the die sleeve inwall of mould.But in existing mould, die sleeve is
Non-disconnectable fixation is integrally disposed upon on die holder, and during the material of stand, stand material scraper is to need to be held with die sleeve epimere inwall
Continuous rigid contact, the epimere inwall for also allowing for die sleeve is spread out material scraper scratch, now needs to repair the inwall of die sleeve
It is whole, and existing finishing is to pull down whole mould from delivery track to be repaired, this finishing mode will cause die sleeve hypomere
The intact part of inwall is also trimmed, so as to cause mould loss increase, service life to be shortened.
The content of the invention
This utility model aims to provide a kind of high hard grinding wheel forming die sleeve of utilization rate, while additionally provide one kind making
With the mould of the hard grinding wheel forming die sleeve.
To solve above-mentioned technical problem, the technical scheme of hard grinding wheel forming die sleeve is as follows in this utility model：
Hard grinding wheel forming die sleeve, including the die sleeve main body of pipe box shape, the internal face of die sleeve main body is inner cylinder face, outer
Side face is external cylindrical surface, and slot pulling is symmetrically offered on the two ends periphery of die sleeve main body, and slot pulling of the die sleeve main body per one end is ring
Shape or in circumferentially-spaced distribution.
Slot pulling is annular, and the cross section of slot pulling is rectangle.
The ring end face at die sleeve main body two ends is the plane perpendicular to central axis.
The technical scheme of mould is as follows in this utility model：
Mould, including die holder and the die sleeve that arranges thereon, offer the installing hole for extending up and down on die holder, the die sleeve can
Tear open and be inserted in installing hole, the die sleeve main body of die sleeve including pipe box shape, the internal face of die sleeve main body is that inner cylinder face, outer peripheral face are
External cylindrical surface, symmetrically offers slot pulling on the two ends periphery of die sleeve main body, slot pulling of the die sleeve main body per one end be annular or
Circumferentially-spaced distribution.
Slot pulling is annular, and the cross section of slot pulling is rectangle.
The ring end face at die sleeve main body two ends is the plane perpendicular to central axis.
Die holder includes the pedestal for being assemblied in along conveying direction movement on delivery track, and pilot hole is offered on pedestal,
Removable in pilot hole to be fitted with snap ring, snap ring and pilot hole interference fits, the installing hole is the endoporus of snap ring.
The slot pulling at die sleeve two ends is symmetrical in this utility model, and the internal face of die sleeve adopts inner cylinder face, so
When damaging occurs in inwall in die sleeve one end, after can be extracted from die holder die sleeve by slot pulling, die sleeve is reversed and is used, reversed
Die sleeve inwall afterwards be unmarred complete inwall, so as to avoid when one end inwall of die sleeve is damaged, need mould
The problem that whole inwalls of set are repaired so that the two ends of die sleeve can be substituted for each other, improves the utilization rate of die sleeve, extends
The repairing efficiency of die sleeve, reduces the manufacturing cost of emery wheel.
Description of the drawings
Fig. 1 is the structural representation of mould in this utility model；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the structural representation of die sleeve in Fig. 1.
Specific embodiment
The embodiment of mould in this utility model：As depicted in figs. 1 and 2, the mould is mainly by pedestal 1, snap ring 2 and die sleeve
3 three parts constitute, and wherein pedestal 1 is square base, and the center of pedestal 1 offers the pilot hole of circle；Snap ring 2 is annular, is blocked
Ring 2 is inserted in the pilot hole of pedestal 1 and forms square die holder, the outer peripheral face of snap ring 2 and the wall surface of the hole of installing hole with pedestal 1
Between by the way of interference fits, on the one hand ensure that snap ring 2 easily can take out from pedestal 1, on the other hand ensure to block
Reliability of the ring 2 on pedestal 1 is fixed, and the endoporus of snap ring 2 is the installing hole loaded for die sleeve 3；As shown in figure 3, die sleeve 3 is
Circular sleeve structure, die sleeve 3 is removable to be inserted in snap ring 2, and the lower end of die sleeve 3 is sunk in snap ring 2, and the upper end of die sleeve 3 is from snap ring 2
Top expose, the upper and lower ends of die sleeve 3 symmetrically offer the slot pulling 31 of annular, and the cross section of the slot pulling 31 is rectangle, slot pulling
31 form sunk structure and are easy to the hand insertion of staff to be taken on the outer peripheral face of die sleeve 3, by die sleeve 3 from card
Extract in ring 2.
The ring end face of the upper and lower ends of die sleeve 3 is the plane perpendicular to central axis, and two end ring end faces of die sleeve 3 are mutual
Symmetrically.
Mould when in use, is being run in the case that the epimere inwall of die sleeve 3 weares and teares in the present embodiment, grasps slot pulling,
Die sleeve 3 is extracted from die holder；Then, reinsert in die holder after is reversed die sleeve and be continuing with.
The other embodiment of mould in this utility model：Slot pulling can also be interrupted, i.e., slot pulling has multiple and in die sleeve
It is circumferentially-spaced uniform.The end face of the upper and lower ends of die sleeve can also be arc.
The embodiment of hard grinding wheel forming die sleeve in this utility model：Hard grinding wheel forming die sleeve in the present embodiment
Structure is identical with the structure of die sleeve in above-described embodiment, therefore repeats no more.
