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 the 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, artificially on blank rotating machine then process the inner surface of porcelain insulator, artificially then be transported to trimming machine from blank rotating machine with cutter; And upset porcelain insulator blank, artificial again outer surface with cutter processing porcelain insulator.Shortcoming is that most of operation is manually-operated, and equipment falls behind, and labour intensity is big, and product quality mainly leans on operator's experience to judge, quality is stable inadequately, and yield rate is low, and operating efficiency is also very low.Simultaneously, in the existing technology, most of pug work in-process of blank is drawn away by cutter, and waste is serious.
Summary of the invention
The objective of the invention is to: a kind of porcelain insulator blank mould pressing method and device are provided, and automaticity is high, and the quality and the dimensional accuracy that improve product are high.
The present invention constitutes like this: porcelain insulator blank mould pressing method; Columniform pug is become the pie blank with the mould precompressed; The pie blank obtains the porcelain insulator blank of design shape through mold pressing, and in mold process, blank continues rotation; Blank is come off by the mould adhesion when preventing the demoulding, 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 is during the blank mold pressing, at blank upper surface spraying releasing agent.
Porcelain insulator blank molding device comprises prepressing device, comprises that also molding device, molding device comprise mold and bed die, below bed die, connects electric rotating machine, above mold, connects lift cylinder.
Above-mentioned porcelain insulator blank molding device, said mold is provided with the releasing agent nozzle.
Above-mentioned porcelain insulator blank molding device, said mold is provided with air nozzle.
Above-mentioned porcelain insulator blank molding device, said bottom mold surface is provided with gypsic horizon.
The invention discloses operation, blank through after the mold pressing, can be obtained porcelain insulator shape roughly, make things convenient for following process, reduce the use of porcelain insulator blank pug the compression molding of porcelain insulator blank.While can also push moulding to blank, improves blank inner intensity and electric property.In R&D process, the applicant finds, because complex-shaped (as shown in Figure 2) of porcelain insulator blank; Its edge is too high, and blank marginal portion pug is very few, and inner bonding force is not enough; If just adopt common mould pressing technology, after its mould and blank pressurized were bonding, mold clung the pug at edge easily during the demoulding; Destroy the shape of blank, so fast rotational, the mode that low speed presses down are adopted in mold pressing; Make blank in mold process, carry out relative motion with mold all the time, the phenomenon of foundry loam can when the demoulding, not occur, improved ratio defective product; And the porcelain insulator blank also will carry out the processing of follow-up cutter and just can obtain final product, and the rotation mold pressing can not influence the precision of blank shape.Through applicant's test, technology of the present invention can reduce by 30% pug consumption, improves 20% efficient, and the defect rate of product is lower than 5%.Compare with prior art, the present invention has the following advantages: 1) reduce manually-operated intensity; 2) the product precision is high, steady quality; 3) appropriate products quantity is wide; 4) enhance productivity: 5) reduce the pug use amount, reduce product cost.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is the structural representation of dish type porcelain insulator.
The specific embodiment
Embodiments of the invention: porcelain insulator blank molding device; As shown in Figure 1; Comprise the prepressing device 1 that blank is carried out precompressed, on prepressing device 2 next doors 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.Releasing agent nozzle 7 is installed in mold 3, and releasing agent nozzle 7 connects the releasing agent spraying equipment, prevents that blank and mold 3 are bonding.
At bed die 4 surface-coated gypsic horizons 9, in mold process, enough frictional force can be arranged, drive blank and rotate, also be convenient to during the demoulding separate, be difficult for clinging pug.
Prepressing device 1 also is divided into mould up and down, and the pug that cuts off is pressed into pie roughly, and the shape of its bed die is similar with bed die 4 shapes of molding device 2, makes things convenient for the fixing and following process of blank in molding device 2 bed dies 4.
The course of work is following: columniform pug is become the pie blank with the mould precompressed of prepressing device 1; The pie blank obtains the porcelain insulator blank of design shape through molding device 2 mold pressings, and in mold process, bed die 4 is driven by electric rotating machine 5; Make blank continue rotation; Keep relative motion with mold 3, blank is come off by the mould adhesion when preventing the demoulding, destroys the profile of blank.
Through test, the speed of blank rotation is 200-400 rev/min, can satisfy the requirement of rotation mold pressing, can in mold process, the rotation because of blank not cause the blank compressive deformation, and reach desirable shape requirement.Special, the speed of blank rotation is 250-350 rev/min, effect is best.
More convenient for the demoulding, blank through the releasing agent nozzle 7 in the mold 3, continues the spraying releasing agent at the blank upper surface when mold pressing.Releasing agent is purchased existing finished product.
