A kind of vibration polishing method of seal stone
Technical field
The invention belongs to seal stone processing technique fields, and in particular to a kind of vibration polishing method of seal stone.
Background technique
In Chinese tradition stone culture, seal stone has particularly important status.The engraving of initial seal stone is pure hand
Work processing, the appearance of then various semi-automatic engraving boards, can come to carry out seal stone with hand fit's semi-automation machinery
Processing, improves the efficiency of manual processing.With the development of economy, seal made of stones has become people when buying seal stone
Main selection.Traditional hand engraving and polishing efficiency has been unable to satisfy demand.The engraving of seal stone has had automatically at present
Change lathe and mechanical arm to be processed, but since seal stone is not flat work pieces, hand can only be used in terms of polishing
The mode of work polishing.Hand polish seal stone has following disadvantage: 1. low efficiencys: for shaped face, need to arrange in pairs or groups abrasive band, cotton
The polishing such as label, hairbrush, process complexity lead to inefficiency;2. risk is high: can directly contact abrasive material in polishing process, polishing produces
It will affect operator's health after raw dust sucking.
Existing vibropolish be able to solve above-mentioned hand polish there are the problem of, vibropolish is also known as vibration finishing skill
Art, starts from the 1950s, be that a certain proportion of workpiece, abrading block and liquid medium are fitted into the container of certain shapes, when
When container vibrates under specific amplitude and frequency, workpiece and abrading block are moved by certain track.Those of ordinary skill in the art
It is found that polishing tool used in vibropolish polishing hard workpiece (jade and pearl etc.) is the harder material such as green triangle.
But the characteristics such as dry are afraid of since seal stone is frangible, directly seal stone are caused with traditional abrading block (green triangle etc.) handling ease larger
Damage.
Summary of the invention
It is an object of the invention to overcome prior art defect, a kind of vibration polishing method of seal stone is provided.
Technical scheme is as follows:
A kind of vibration polishing method of seal stone, includes the following steps:
(1) by the size and material of polished seal stone, select aqueous flexible polishing tool and power for 30~50w and
Working cavity be 5~7.5L vibratory finishing machine, above-mentioned aqueous flexible polishing tool be 3~5mm of diameter flexible gel ball or
The positive tetrahedron flexible polishing block of 3~5mm of side length, above-mentioned flexible gel ball and positive tetrahedron flexible polishing block are upper to be had uniformly
The hard abrasive that the partial size of distribution is 20~40 μm;
(2) it is put into appropriate aqueous flexible polishing tool and polished seal stone in above-mentioned working cavity, opens vibration
Polishing machine runs 4~8h with the revolving speed of 1300~1500rpm and 4~6 ° of angle of throw, then takes out aqueous flexible polishing tool
With seal stone, aqueous flexible polishing tool and seal stone are put into after being cleaned in clear water, are further continued for being put into the above-mentioned work after cleaning
Make to open vibratory finishing machine in cavity with 4~8h of the revolving speed of 1300~1500rpm and the operation of 4~6 ° of angle of throw;Repeat the step
Suddenly, until vibratory finishing machine runs to the 3rd~5 time and finishes.
In a preferred embodiment of the invention, the material of the flexible gel ball is sodium alginate.
In a preferred embodiment of the invention, the material of the positive tetrahedron flexible polishing block is gelatin.
In a preferred embodiment of the invention, the material of the hard abrasive is aluminium oxide.
It is further preferred that step (2) are repeated, until vibratory finishing machine runs to the 4th and finishes.
The beneficial effects of the present invention are:
1, the present invention uses vibratory finishing machine automation polishing, is a kind of processing method that automation is economic;
2, present invention uses vibratory finishing machine automations to polish, since the working cavity of vibratory finishing machine sealing ensure that
Without dust in whole process, operator's health will not be damaged;
3, present invention uses vibratory finishing machine automations to polish, can be simultaneously due to the forms of motion of vibratory finishing machine
Multiple workpiece are carried out with the polishing of all angles;
4, present invention uses a kind of aqueous flexible polishing tools, will not be to workpiece when processing because of its flexible aqueous feature
Cause damage and it is dry and cracked.
