Abstract
The invention discloses a processing process for a fuse porcelain bushing. An integrally-formed fuse porcelain bushing is manufactured by a one-step molding process of vacuum extruded pug, so that process steps are reduced and labor intensity is lowered; meanwhile, the fuse porcelain bushing is molded by one step through extruding pug in vacuum, therefore, a bonding gap does not exist on the fuse porcelain bushing, and strength of the fuse porcelain bushing is improved; meanwhile, internal molecular structure of a blank is guaranteed to be compact, so that gas pores are prevented from forming inside a product, therefore, qualified rate of the product is improved; besides, the one-step molded fuse porcelain bushing does not appear a cracking phenomenon in a drying process, so that special treatment is not needed to be carried out onto the surface of the blank, therefore, qualified rate of the product is improved, qualified rate of the product is over 98%, product scrappage is effectively reduced, production cost is lowered, large-scale processing can be realized, and production efficiency is high. The glaze slip concentration is controlled to 42 Baume degrees, therefore, a glaze layer coated on the fuse porcelain bushing blank is fine and uniform, and phenomena such as pores, glaze beads, glaze peels, and the like, are avoided.
Description
Technical field
The present invention relates to fusible cut-out insulator complete processing.
Background technology
At present, fusible cut-out insulator adopts mold injection molding, and injection molding process requires very high to pug plasticity-, in addition, injection moulding process, easily produces bubble in pug, there are a lot of pores and the product that causes moulding is inner after burning till, have a strong impact on the quality of product, because interiors of products mass defect is difficult for finding, therefore, cause the product qualified rate of burning till to be no more than 60%, thereby, reduce production efficiency, improve production cost.In addition, injection moulding withering product surface are difficult for processing, and work for the treatment of amount is large, has increased labour intensity.
Summary of the invention
The present invention aim to provide a kind of can disposal molding and can avoid interiors of products to occur the fusible cut-out insulator complete processing of pore.
A kind of fusible cut-out insulator complete processing of the present invention, its step is as follows:
1) mud processed: 30% outlet mud, 9% Fujian mud, 18% Jiepai clay, 4% Feldspar Powder, Shaoguan mud of 27% and 12% Suzhou mud are mixed, the fineness of the mud mixing is controlled between 0.3 ~ 0.4, and satisfactory mud is carried out to old placement more than 30 days;
2) moulding: detect the moisture of the pug of making, make its moisture controlled between 22% ~ 23%, pug is positioned in corresponding mould, revise pug, and dig inner umbrella rib, rest and reorganization blank profile, pressed blanks subsequently, the blank suppressing is taken out, grooving on blank, thereby disposal molding blank, deposit the blank of forming after 1 ~ 2 day and be dried, drying temperature is controlled in 80 DEG C, is controlled at 4 ~ 5 days time of drying;
3) glazing: glaze slip is stirred, make concentration of glaze slip be controlled at 42 Baume gravities, the glaze slip modulating is coated on fusible cut-out porcelain bushing blank;
4) dress burns: glazy fusible cut-out porcelain bushing blank is burnt till, control firing time at 45 hours, the product that taking-up is burnt till subsequently carries out cooling, and fusible cut-out insulator completes.
A kind of fusible cut-out insulator complete processing of the present invention, extrude pug once through moulding technology by vacuum, by multiple forming moulds and revolve cutter processed and be used in conjunction with on same board, in the time of turnery profile, simultaneously that blank internal structure is good by other several mould disposal moldings, thereby produce integrated fusible cut-out insulator, avoid the technique to the injection moulding of fusible cut-out insulator in prior art, thereby avoid injection moulding to the plastic requirement of material, simultaneously, because this kind of vacuum extrudes pug once through moulding technology, without using injection moulding, coordinate by turning and internal structure mould, thereby moulded blank, therefore, without processing after injection moulding and dry blank surface, reduce labour intensity, simultaneously, because this kind of fusible cut-out insulator is by turning machine-shaping, therefore, the a large amount of gas hole defects that produce while having avoided injection moulding, improve the intensity of fusible cut-out insulator, simultaneously, guarantee the tight of blank interior molecules structure, avoid interiors of products to produce pore, improve the qualification rate of product, in addition, the fusible cut-out insulator of disposal molding, it also there will not be cracking phenomena in drying process, thereby without special processing is carried out in blank surface, improve the qualification rate of product, conforming product rate is reached more than 98%, effectively reduce product rejection, reduced production cost, also can realize the mass of processing, production efficiency is high.Because concentration of glaze slip is controlled at 42 Baume gravities, therefore, be coated in glaze layer on fusible cut-out porcelain bushing blank evenly fine and smooth, there will not be pore, enamel drops, lack the phenomenons such as glaze.
Embodiment
A kind of fusible cut-out insulator complete processing of the present invention, its step is as follows: (1) mud processed: 30% outlet mud, 9% Fujian mud, 18% Jiepai clay, 4% Feldspar Powder, Shaoguan mud of 27% and 12% Suzhou mud are mixed, the fineness of the mud mixing is controlled between 0.3 ~ 0.4, and satisfactory mud is carried out to old placement more than 30 days; (2) moulding: detect the moisture of the pug of making, make its moisture controlled between 22% ~ 23%, pug is positioned in corresponding mould, revise pug, and dig inner umbrella rib, rest and reorganization blank profile, pressed blanks subsequently, the blank suppressing is taken out, grooving on blank, thereby disposal molding blank, deposit the blank of forming after 1 ~ 2 day and be dried, drying temperature is controlled in 80 DEG C, is controlled at 4 ~ 5 days time of drying; (3) glazing: glaze slip is stirred, make concentration of glaze slip be controlled at 42 Baume gravities, the glaze slip modulating is coated on fusible cut-out porcelain bushing blank; (4) dress burns: glazy fusible cut-out porcelain bushing blank is burnt till, control firing time at 45 hours, the product that taking-up is burnt till subsequently carries out cooling, and fusible cut-out insulator completes.
In step 1, after each starting material are mixed, by ball-milling technology, moil fineness is controlled between 0.3 ~ 0.4.By ball-milling technology abrasive slurry, can conveniently control moil fineness.
In step 2, the good blank of disposal molding is removed to surperficial corner angle, and will remove the smooth placement of blank of corner angle, be out of shape, lose the phenomenons such as circle with smooth, the nothing of guaranteeing blank.
In step 3, before being blank glazing, blank need being contrasted to corresponding drawing and detect, remove defective blank, and qualified blank is repaiied scrape, round edge processing, and to the processing of waxing of not glazing of blank part, to ensure that follow-up glazing technology carries out smoothly.
In step 4, control cooling time at 15 ~ 21 hours, fully cooling to ensure product, guarantee that quality product is good.
In step 2 and step 4, in the time that blank is heated, need evenly heat up, ensure that blank is heated and envrionment temperature is even, prevent that blank heart portion and surperficial heat-up rate are inconsistent, guarantee the quality of blank.
