Abstract
A kind of mold the present invention relates to hard grinding wheel forming die sleeve and using the die sleeve.Hard grinding wheel includes the die sleeve main body of pipe sleeve shape with forming die sleeve, the internal face of die sleeve main body is inner cylinder face, outer circumferential surface is external cylindrical surface, symmetrically offer slot pulling on the both ends periphery of die sleeve main body, slot pulling of the die sleeve main body per one end is annular or in circumferentially-spaced distribution.When inner wall in die sleeve one end damages, after die sleeve can be extracted from die holder by slot pulling, die sleeve is reversed and is used, die sleeve inner wall after reversing is unmarred complete inner wall, so as to avoid when one end inner wall of die sleeve damages, need to be modified whole inner walls of die sleeve the problem of so that the both ends of die sleeve can be substituted for each other, and improve the utilization rate of die sleeve, the repairing efficiency of die sleeve is extended, reduces the manufacture cost of emery wheel.
Description
Technical field
A kind of mold the present invention relates to hard grinding wheel forming die sleeve and using the die sleeve.
Background technology
At present, prepared by the production of hard grinding wheel carries out in a mold, i.e., is first put into abrasive material in a mold, treats that abrasive material is spread out
After flat, fiber mat is put on abrasive material, then abrasive material in mold is heated and squeezed, abrasive material is pressed into a mold
Finished grinding wheel.In the process, to ensure the precision of emery wheel compression moulding, the die sleeve inner wall smooth of mold need to be kept, is also just needed
Often mold from pipeline to be unloaded, polishing finishing is carried out to the die sleeve inner wall of mold.But in existing mold, die sleeve is
Non-disconnectable fixation is integrally disposed upon on die holder, and during expecting at stand, stand material scraper is to need to hold with die sleeve epimere inner wall
Continuous rigid contact, the epimere inner wall for also allowing for die sleeve are scratched by stand material scraper, need to repair the inner wall of die sleeve at this time
It is whole, and existing finishing is to remove entire mold from delivery track to modify, this finishing mode will be so that die sleeve hypomere
The intact part of inner wall is also trimmed, and is lost and is increased so as to cause mold, reduced service life.
The content of the invention
The present invention is intended to provide the hard grinding wheel forming die sleeve that a kind of utilization rate is high, while additionally provide a kind of use and be somebody's turn to do
The mold of hard grinding wheel forming die sleeve.
In order to solve the above technical problems, the technical solution of hard grinding wheel forming die sleeve is as follows in the present invention：
Hard grinding wheel forming die sleeve, the die sleeve main body including pipe sleeve shape, the internal face of die sleeve main body is inner cylinder face, outer circumferential surface
For external cylindrical surface, symmetrically offer slot pulling on the both ends periphery of die sleeve main body, slot pulling of the die sleeve main body per one end be annular 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 both ends is the plane perpendicular to central axis.
The technical solution of mold is as follows in the present invention：
Mold, the die sleeve set including die holder and thereon offer the mounting hole extended up and down on die holder, and the die sleeve is removable to be inserted
In mounting hole, die sleeve includes the die sleeve main body of pipe sleeve shape, and the internal face of die sleeve main body is inner cylinder face, outer circumferential surface is outer circle
Cylinder, symmetrically offers slot pulling on the both ends periphery of die sleeve main body, and slot pulling of the die sleeve main body per one end is annular or in circumferential direction
It is spaced apart.
Slot pulling is annular, and the cross section of slot pulling is rectangle.
The ring end face at die sleeve main body both ends is the plane perpendicular to central axis.
Die holder includes moving the pedestal being assemblied on delivery track along conveying direction, and pilot hole is offered on pedestal,
Removable in pilot hole to be fitted with snap ring, snap ring coordinates with pilot hole transition, and the mounting hole is the endoporus of snap ring.
The slot pulling at die sleeve both ends is symmetrical in the present invention, and the internal face of die sleeve uses inner cylinder face, so in mould
When the inner wall of set one end damages, after die sleeve can be extracted from die holder by slot pulling, die sleeve is reversed and is used, after reversing
Die sleeve inner wall be unmarred complete inner wall, so as to avoid when one end inner wall of die sleeve damages, need die sleeve
The problem of whole inner walls are modified so that the both ends of die sleeve can be substituted for each other, and improved the utilization rate of die sleeve, extended die sleeve
Repairing efficiency, reduce the manufacture cost of emery wheel.
Description of the drawings
Fig. 1 is the structure diagram of mold in the present invention；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the structure diagram of die sleeve in Fig. 1.
Specific embodiment
The embodiment of mold in the present invention：As depicted in figs. 1 and 2, the mold is mainly by pedestal 1, snap ring 2 and die sleeve 3 three
Part forms, and wherein pedestal 1 is square base, and the center of pedestal 1 offers circular pilot hole；Snap ring 2 be circular ring shape, snap ring 2
Be inserted into the pilot hole of pedestal 1 and form square die holder with pedestal 1, the outer circumferential surface of snap ring 2 and the wall surface of the hole of mounting hole it
Between using transition cooperation by the way of, on the one hand ensure snap ring 2 can easily be taken out from pedestal 1, on the other hand ensure snap ring 2
Being reliably fixed on pedestal 1, and the endoporus of snap ring 2 is the mounting hole being packed into for die sleeve 3；As shown in figure 3, die sleeve 3 is circle
Shape sleeve structure, die sleeve 3 is removable to be inserted into 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 is exposed, and 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
Sunk structure is formed on the outer circumferential surface of die sleeve 3 and is taken convenient for the hand insertion of staff, by die sleeve 3 from snap ring
It is extracted in 2.
The ring end face of 3 upper and lower ends of die sleeve is the plane perpendicular to central axis, and two end ring end faces of die sleeve 3 are mutual
Symmetrically.
Mold when in use, in the case where running into 3 epimere inner wall of die sleeve and wearing, grasps slot pulling in the present embodiment,
Die sleeve 3 is extracted from die holder；Then, reinsert in die holder and be continuing with after die sleeve is reversed.
The other embodiment of mold in the present invention：Slot pulling can also be interrupted, i.e., slot pulling has multiple and in the week of die sleeve
To uniformly at intervals.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 the present invention：The structure of hard grinding wheel forming die sleeve in the present embodiment
It is identical with the structure of die sleeve in above-described embodiment, therefore repeat no more.
