Abstract
The invention discloses a die pressing method and a device for a blank of a porcelain insulator. A cylindrical mud material is prepressed into a cake shape by using a die. The die pressing method and the device for the blank of the porcelain insulator are characterized in that a blank of a porcelain insulator, which has a designed shape, is obtained by die pressing; and the blank rotates continuously in the die pressing process so as to prevent that the appearance of the blank is destroyed because the blank is stuck to fall off by the die during stripping. According to the process disclosed by the invention, the use quantity of the mud material can be lowered by 30 percent, the efficiency is enhanced by 20 percent, and the defective rate of a product is lower than 5 percent. Compared with the prior art, the die pressing method and the device for the blank of the porcelain insulator have the following advantages that: (1) the strength of the manual operation is lowered; (2) the product has high accuracy and stable quality; (3) the number of applicable products is large; (4) the production efficiency is enhanced; and (5) the use quantity of the mud material is lowered, and the cost of the product is lowered.
Description
Technical field
The present invention relates to a kind of porcelain insulator blank mould pressing method and device, belong to porcelain insulator processing technique field.
Background technology
The blank of dish type porcelain insulator processing at present, after normally pug being extruded, slightly be pressed into bulk, then on blank rotating machine, manually go out the inner surface of porcelain insulator with tool sharpening, then be manually transported to trimming machine from blank rotating machine, and the porcelain insulator blank that overturns, more manually use the outer surface of tool sharpening porcelain insulator.Shortcoming is that most of operation is manual operation, and equipment falls behind, and labour intensity is large, and product quality is mainly by operator's micro-judgment, and quality is stable not, and yield rate is low, and operating efficiency is also very low.Meanwhile, in existing technique, most of pug work in-process of blank is drawn away by cutter, and waste is serious.
Summary of the invention
The object of the invention is to: a kind of porcelain insulator blank mould pressing method and device are provided, and automaticity is high, the quality and the dimensional accuracy that improve product are high.
The present invention forms like this: porcelain insulator blank mould pressing method, columniform pug is pressed into pie blank in advance with mould, pie blank obtains the porcelain insulator blank of design shape by mold pressing, in mold process, blank continues rotation, while preventing the demoulding, blank is come off by mould adhesion, destroys the profile of blank.
Above-mentioned porcelain insulator blank mould pressing method, the speed of blank rotation is 200-400 rev/min.
Above-mentioned porcelain insulator blank mould pressing method, the speed of blank rotation is 250-350 rev/min.
Above-mentioned porcelain insulator blank mould pressing method, when blank mold pressing, at blank upper surface spraying releasing agent.
Mould pressing device for porcelain insulator blanks, comprises prepressing device, also comprises that molding device, molding device comprise mold and bed die, connects electric rotating machine below bed die, connects lift cylinder above mold.
Above-mentioned mould pressing device for porcelain insulator blanks, described mold is provided with releasing agent nozzle.
Above-mentioned mould pressing device for porcelain insulator blanks, described mold is provided with air nozzle.
Above-mentioned mould pressing device for porcelain insulator blanks, described bottom mold surface is provided with gypsic horizon.
The invention discloses the operation to the compression molding of porcelain insulator blank, blank, after mold pressing, can be obtained to porcelain insulator shape roughly, facilitate following process, reduce the use of porcelain insulator blank pug.While can also push blank moulding, improves intensity and the electric property of blank inside.In R&D process, applicant finds, due to complex-shaped (as shown in Figure 2) of porcelain insulator blank, its edge is too high, blank marginal portion pug is very few, inner bonding force is inadequate, if just adopt common mould pressing technology, after its mould and blank pressurized are bonding, when the demoulding, mold easily clings the pug at edge, destroy the shape of blank, therefore mold pressing adopts fast rotational, the mode that low speed presses down, make blank carry out relative motion with mold all the time in mold process, can in the time of the demoulding, there is not the phenomenon of foundry loam, improve ratio defective product, and also will carrying out follow-up tool sharpening, porcelain insulator blank just can obtain final product, rotation mold pressing can not affect the precision of blank shape.Through applicant's test, technique of the present invention, can reduce by 30% pug consumption, improves 20% efficiency, and the defect rate of product is lower than 5%.Compared with the existing technology, the present invention has the following advantages: 1) reduce manual operation intensity; 2) Product Precision is high, steady quality; 3) appropriate products quantity is wide; 4) enhance productivity: 5) reduce pug use amount, reduce product cost.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is the structural representation of dish type porcelain insulator.
Detailed description of the invention
Embodiments of the invention: mould pressing device for porcelain insulator blanks, as shown in Figure 1, comprise the prepressing device 1 that blank is carried out to precompressed, on prepressing device 2 sides, molding device 2 is set, the structure of molding device 2 comprises mold 3 and bed die 4, below bed die 4, connect electric rotating machine 5, above mold 3, connect lift cylinder 6.At the interior installation releasing agent of mold 3 nozzle 7, releasing agent nozzle 7 connects releasing agent spraying equipment, prevents that blank and mold 3 are bonding.
At the interior installation air nozzle 8 of mold 3, air nozzle 8 connects air compressor machine, after blank mold pressing, can remove the residual pug in mold.
Apply gypsic horizon 9 on bed die 4 surfaces, in mold process, can have enough frictional force, drive blank to rotate, when the demoulding, be also convenient to separate, be difficult for clinging pug.
The course of work is as follows: columniform pug is pressed into pie blank in advance with the mould of prepressing device 1, pie blank obtains the porcelain insulator blank of design shape by molding device 2 mold pressings, in mold process, bed die 4 is driven by electric rotating machine 5, make blank continue rotation, keep relative motion with mold 3, while preventing the demoulding, blank is come off by mould adhesion, destroys the profile of blank.
Through test, the speed of blank rotation is 200-400 rev/min, can meet the requirement of rotation mold pressing, can be because the rotation of blank causes blank compressive deformation in mold process, and reach desirable shape requirement.Especially, the speed of blank rotation is 250-350 rev/min, and effect is best.
More convenient for the demoulding, blank, in the time of mold pressing, by the releasing agent nozzle 7 in mold 3, continues spraying releasing agent at blank upper surface.Releasing agent is purchased existing finished product.
