Abstract
The invention relates to a coil forming method and a forming die for electromagnetic metering equipment, wherein the method comprises the following steps: (1) mounting a winding former on an automatic winding machine and fixing; (2) winding by a winding machine to obtain a wound coil, and winding the surface of the coil by an insulating tape; (3) opening a forming die, placing an insulating layer on the upper die and the lower die, placing the coil into the lower die, closing the die, pressing the coil tightly by using the upper die, setting the current intensity of a voltage regulator in the heating die, heating the coil at 155-165 ℃, and keeping the temperature for 2-6 minutes; (4) and (3) cooling the coil to 55-65 ℃, and taking out the coil to obtain the coil for the electromagnetic metering equipment. The invention can ensure the precision of the coils, the coils are arranged neatly and compactly, and the magnetic flux leakage is reduced in the using process, so that the magnetic flux discreteness is reduced, and the invention is suitable for large-batch industrial production of enterprises.
Description
Technical field
The invention belongs to a kind of method and apparatus that relates to a kind of coil molding, particularly a kind of coil molding method and mould that is used for electromagnetic metering equipment.
Background technology
The coil that is used for electromagnetic metering equipment, its end face are have cambered surface circular-arc.Because it is the accuracy class of electromagnetic measurement device is high, and accuracy class is high more, just high more to the requirement of coil electric performance and mechanical dimension.Usually the preparation process of coil is a coiling on winding former earlier, again to winding the coil integer of line.At present, the manufacturing enterprise of coil adopts offhand mostly to the integer of coil, and this method is difficult to guarantee the dimensional accuracy of coil, and coil is not fine and close, misaligned.In use the coil leakage field is big, and the magnetic flux discreteness of generation is big, directly causes the measurement result of electromagnetic metering equipment inaccurate.
Summary of the invention
The present invention has overcome above-mentioned shortcoming, and a kind of coil molding method and mould that is used for electromagnetic metering equipment is provided.It can guarantee the precision of coil, and coil arrangement is neat, fine and close, in use reduces leakage field, and the magnetic flux discreteness is reduced, and is fit to the large batch of commercial production of enterprise.
Technical scheme of the present invention is:
Be used for the coil molding method of electromagnetic metering equipment, following steps arranged:
(1) winding former is installed on the automatic coil winding machine, fixing;
(2) the coil winding machine coiling coil that obtains winding twines coil surface with insulating tape;
(3) be opened into type die, lay insulating barrier at upper and lower mould, coil is put in the counterdie, matched moulds is used mold pressing stringing circle, sets the current strength of voltage regulator in the heating mould, with 155～165 ℃ of coil heats, keeps 2～6 minutes;
(4) treat that coil is cooled to 55～65 ℃, take out coil, promptly get the coil that is used for electromagnetic metering equipment of the present invention.
The mould that is used for the coil molding of electromagnetic metering equipment; Comprise upper die and lower die, patrix is the upwards die of depression of die cavity, and counterdie is that die cavity is the punch to upper process; The bottom surface of counterdie die cavity is provided with down the plane that both ends of the surface are extended; Be fixed with guide vane end stop on the said plane, upper die and lower die are through screw, liner with pass upper die and lower die and its matched in clearance.
The inventive method makes coil softening through energising, adopts special-purpose mould to make coil molding then.The die cavity of mould can design according to the shape and the full power rate of groove of coil, and the circular-arc cambered surface of the die cavity of mould is consistent with the circular-arc cambered surface of the end face of coil, has guaranteed the consistency of prepared coil dimension.
Adopt the inventive method, can process the coil of bore DN200 at present with interior different shape.
The present invention can guarantee the precision of coil, and coil arrangement is neat, fine and close, in use reduces leakage field, and the magnetic flux discreteness is reduced, and processing technology is easy to control, is fit to the large batch of commercial production of enterprise.
Description of drawings
Fig. 1 is the structural representation of mould.
Among the figure, 1 is screw, and 2 is packing ring, and 3 is patrix, and 4 is liner, and 5 is counterdie, 6 guide vane end stops, and 7 is coil, 8 is insulating barrier.
Embodiment
Referring to Fig. 1, be used for the mould of the coil molding of electromagnetic metering equipment, patrix 3 is the die of die cavity for upwards caving in, counterdie 5 is the punch arc of die cavity to upper process, forms the radian and the identical mould of coil end face radian of die cavity.Be provided with the plane of both ends of the surface extension down in the bottom surface of counterdie die cavity; With the guide vane end stop 6 of bolt, wherein the height of guide vane end stop equals the thickness of coil on the said plane, is used for limiting the position that is installed in the mould coil; Upper die and lower die are fixing through screw 1, and upper and lower mould is fixed and clamped.Liner 7 with pass upper die and lower die and its matched in clearance.
When being used for the coil molding of electromagnetic metering equipment, earlier winding former is installed on the automatic coil winding machine, fixed.According to the parameter of the specific requirement of coil adjustment coil winding machine, set back operation automatic coil winding machine, the coil that obtains winding.Take out coil, (J-236) twines coil surface with the high-temperature insulation band.
Be opened into type die, insulating barrier 8 be installed, with coil and mould insulation at upper and lower mould.Coil 7 is put in the counterdie, and liner 4 is passed counterdie, matched moulds, and liner 4 passes patrix again, and the end face of screw 1 to the patrix of screwing is pressed on uses mold pressing stringing circle on the guide vane end stop 6, lay packing ring 2 between screw 1 and the patrix, and patrix is compressed coil better.Set the current strength of coil heats, current strength is arranged on 2.5～4A according to the specifications and models difference of coil, specifically referring to table 1.With 155～165 ℃ of coil heats, kept 2～6 minutes.Subsequently, coil cools off in room temperature, treats that coil is cooled to 55～65 ℃, takes out coil, promptly gets the coil that is used for electromagnetic metering equipment of the present invention.
The conduction time and the current strength of table 1 coil integer
Though; The present invention is clearly demonstrated through above embodiment; Yet under the situation that does not deviate from spirit of the present invention and essence thereof; The person of ordinary skill in the field works as can make various corresponding variations and correction according to the present invention, but these corresponding variations and correction all should belong to the protection range of claim of the present invention.
