Abstract
The invention relates to a forming die for superhard grinding wheels. The forming die comprises a die holder which is movably assembled on a conveying device in the conveying direction, the die holder is provided with a mounting hole which extends vertically, and a die sleeve used for storing abrasive materials is detachably inserted into the mounting hole. After the specifications of the grinding wheels needing to be produced are changed, the specification of the forming die is changed by replacing the die sleeves on the die holder through the characteristic that the inner diameters of the die sleeves of different specifications are different, and therefore the grinding wheels of different specifications are produced under the condition that the die is not replaced frequently; and accordingly, the forming die has the advantages that the universality is high, and replacement is convenient.
Description
Technical field
The present invention relates to a kind of hard grinding wheel mould.
Background technology
The preparation that produces of hard grinding wheel is carried out in a mold, first puts into abrasive material in a mold, after abrasive material shakeouts,
Fiber mat is put on abrasive material, then abrasive material in mould is heated and extrude, abrasive material is pressed in a mold emery wheel
Finished product.In the process, the precision compressing for ensureing emery wheel, need to keep the die sleeve inner wall smooth of mould, when being also accomplished by
Often mould is unloaded from pipeline, polishing finishing is carried out to the die sleeve inwall of mould.But in existing mould, die sleeve is can not
Tear open fixing or be integrally disposed upon on die holder, the endoporus of die sleeve is to mate with the size of emery wheel product, thus this mould is special
For fixing the production in enormous quantities of the emery wheel of specification, many specifications emery wheel is produced in batches it is necessary to change different moulds
Carry out, be related in the middle of this carry out shutting down on process units change a complete set of mould, so on the one hand need to mould in production line
On arrangement mode redesigned, on the other hand need to prepare many molds, thus causing replacement cycle length to become with equipment
This big problem.Meanwhile, during the material of stand, stand material scraper is to need the rigid contact lasting with die sleeve inwall, also allows for
The epimere inwall of die sleeve is spread out material scraper scratch, now needs the inwall of die sleeve is repaired, and existing finishing is will be whole
Mould is pulled down from delivery track and is repaired, and this finishing mode will increase the finishing cost of mould.
Content of the invention
The present invention is intended to provide a kind of hard grinding wheel mould, to solve the poor universality of mould in prior art
Problem.
For solving above-mentioned technical problem, in the present invention, the technical scheme of hard grinding wheel mould is as follows:
Hard grinding wheel mould, including for the die holder on a conveyor along the mobile assembling of conveying direction, die holder is opened
It is provided with the installing hole extending up and down, the removable die sleeve being fitted with for holding abrasive material in installing hole.
Die sleeve includes the removable snap ring being inserted in installing hole and the modular ring being inserted in snap ring, snap ring and installing hole transition
Cooperation.
The upper end of snap ring is provided with the limiting block edge of projection annular on the outer periphery, the ring end face directed downwardly on limiting block edge and mould
Seat block cooperation.
Installing hole is up big and down small stepped hole, and described limiting block is along block on the step surface of stepped hole.
The two ends of modular ring symmetrically offer the slot pulling of the annular being on outer peripheral face, and the inside and outside wall of modular ring is cylinder
Face.
Die holder is square pedestal.
The upper end of die sleeve is stretched out from the top of die holder.
In the present invention, die sleeve is can be removable in the installing hole of die holder, and so the emery wheel specification in required production occurs
After change, by way of changing die sleeve on die holder, using the different feature of the die sleeve internal diameter of different size, realize to mould
The change of specification, thus in the case of not to mould replacing all day, realizing producing the emery wheel of different size, solving existing skill
The problem of the poor universality of mould in art, thus in the present invention, mould has versatility height, changes convenient advantage.
Brief description
Fig. 1 is the structural representation of mould in the present invention；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the structural representation of modular ring in Fig. 1.
Specific embodiment
The embodiment of hard grinding wheel mould in the present invention: as depicted in figs. 1 and 2, this mould mainly by die holder 1,
Snap ring 2 and modular ring 3 three part composition, wherein die holder 1 are square base, and the center of die holder 1 offers the installing hole of circle；Snap ring 2
For annular, snap ring 2 is inserted in the pilot hole of die holder 1 and forms square die holder, the outer peripheral face of snap ring 2 and peace with die holder 1
Between the wall surface of the hole in dress hole by the way of interference fits, on the one hand ensure that snap ring 2 can easily take out from die holder 1, separately
On the one hand ensure that reliability on die holder 1 for the snap ring 2 is fixed, and the endoporus of snap ring 2 is the pilot hole loading for modular ring 3；As Fig. 3
Shown, modular ring 3 is circular sleeve structure, and modular ring 3 is removable to be inserted in snap ring 2, and modular ring 3 and snap ring 2 are combined and formed
The die sleeve of removable plug-in mounting in the installing hole of die holder 1.The lower end of modular ring 3 is sunk in snap ring 2, and the upper end of modular ring 3 is upper from snap ring 2
Side exposes.The upper and lower ends of modular ring 3 symmetrically offer the slot pulling 31 of annular, and the cross section of this slot pulling 31 is rectangle, and slot pulling 31 exists
The hand insertion forming sunk structure on the outer peripheral face of modular ring 3 and being easy to staff is taken, by modular ring 3 from snap ring 2
In extract.The ring end face of modular ring 3 upper and lower ends is the plane perpendicular to central axis, and two end ring end faces of modular ring 3 are mutual
Symmetrically.
The upper end of snap ring 2 is provided with the limiting block edge of projection annular on the outer periphery, the ring end face directed downwardly on limiting block edge with
Die holder block coordinates.Installing hole in die holder is up big and down small stepped hole, and the step surface limit block of stepped hole is in modular ring 3
Limiting block is along lower section.
In the present embodiment mould use when, after the emery wheel specification of required production changes, by original die sleeve from
Extracting in die holder 1, then reinsert new die sleeve in die holder 1, thus realizing the change to mould specification, that is, realizing to mould
The change of the internal diameter size of ring 3.
The other embodiment of mould in the present invention: slot pulling can also be interrupted, that is, slot pulling have multiple and in die sleeve week
To uniformly at intervals.The end face of the upper and lower ends of die sleeve can also be arc.Die sleeve can also be only made up of modular ring, now modular ring
Outside wall surface directly coordinate with the wall surface of the hole of installing hole.
