Description

The process of stone kettle is manufactured with siltstone
Technical field
The present invention relates to stone material vessel fabrication technical field, especially relate to the process that a kind of siltstone manufactures stone kettle.
Background technology
Siltstone, also known as boccaro rock or boccaro stone, among the peoplely to be named again " positive spoil ", its sedimentary rock be made up of flour sand chip, and the color of siltstone is varied, and the composition with tramp material is different and become.Siltstone have passed through that long distance carrying, hydrodynamic condition are quieter, deposition velocity formed under environment slowly.Sandstone or clay rock can be crossfaded in the horizontal with in longitudinal direction, and form rhythmic nature bedding.Under siltstone is formed at weak hydrodynamic condition, be often piled up in Diarrhea lake, lake, marsh, alluvial flat, delta and sea basin ground environment.
The outward appearance very attractive of siltstone, stone material itself has good gas permeability and containing the multiple chemistry useful to human body trace element, especially the content of ferro element can chase after than yixing purple sand, is make tea infuser to select preferably.But due to the characteristic of its chiltern, difficulty of processing is large, manufactures field at stone kettle and also do not obtain real development and utilization.
Summary of the invention
Instant invention overcomes shortcoming of the prior art, provide the process that a kind of processed finished products rate is high, the measured siltstone of matter manufactures stone kettle.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of siltstone manufactures the process of stone kettle, utilizes natural siltstone to process, it is characterized in that: comprise following operation:
(1) kettle shape design, the bag according to siltstone designs kettle shape and draws drawing;
(2) make blank, the siltstone of bulk is cut into the blank of fritter according to designing requirement;
(3) blank soaks, and be soaked in by blank in cold water, soak time is no less than two days;
(4) be machined to just type, take out the blank soaked, rule on blank according to design drawing, adopt milling machine and engraving machine milling, carve inner chamber, the outer wall of blank, formation teapot semi-finished product;
(5) kettle mouth is shaping, adopts engraving machine to process kettle mouth profile;
(6) get through Hu Zui, adopt the engraving member High Rotation Speed of 4 ~ 8 millimeters to get through Hu Zui, Hu Zui process of getting through adopts water spray to carry out lubrication cooling process;
(7) kettle is shaping, adopts engraving machine to process kettle handle;
(8) artificial sizing, carries out partial operation to stone kettle by hand, is directly processed to size and the profile of design;
(9) sanding and polishing, carries out sanding and polishing process to the outer surface of kettle body and inner surface, makes the surface that kettle figure becomes smooth;
(10) check, the said goods is tested, is up to the standards, packaging warehouse-in.
Preferably, described siltstone is selected from the argillaceous siltstoue of river, Zhenxiong County, Yunnan abutment.
Preferably, the process of described step (4) carries out water spray lubrication cooling process, and processing temperature controls in 160 DEG C.
Preferably, after described step (9) completes, kettle brush waterproofing agent of organosilicon, in kettle upper formation water vapour, air by and the impervious overcoat of the globule.
Preferably, after described step (9) completes, kettle body Brush for outer wall be coated with waterproofing agent of organosilicon, formed on kettle body outer wall water vapour, air by and the impervious overcoat of the globule.
Compared with prior art, tool of the present invention has the following advantages:
(1) siltstone soaks by the present invention before machined, change the processing characteristics of siltstone, make its work in-process not easily broken, and the moisture contained in the siltstone soaked has cooling lubricating function, greatly improve the processability of siltstone, can do very thin of stone kettle kettle wall of siltstone processing and not easily broken, for the quick production of siltstone processing stone kettle and batch production bring new breakthrough.The siltstone simultaneously soaked also can reduce the airborne dust produced in process.
(2) the present invention by brushing waterproofing agent of organosilicon on kettle handle; because siltstone quality is softer; kettle is very easily polluting in Long-Time Service process; and waterproofing agent of organosilicon coating effectively can be protected formation to kettle; neither affect its gas permeability; also can prevent kettle from being polluted and corrosion by sweat on hand, greasy dirt etc., ensure that its outward appearance can not be out of shape for a long time, there is permanent service life.
