Abstract

The invention relates to a coil forming method and a forming mould for electromagnetic metering equipment. The method comprises the following steps of: (1) mounting a winding former on an automatic winding machine and fixing; (2) winding by the winding machine to obtain a well-wound coil and winding the surface of the coil by using an insulating tape; (3) opening the forming mould and placing insulating layers in the upper mould and the lower mould; putting the coil in the lower mould and closing the mould; pressing the coil by using the upper mould and setting the current intensity of a voltage regulator in a heating mould; heating the coil to 155-165 DEG C and keeping the temperature for 2-6 minutes; and (4) after the coil is cooled to 55-65 DEG C, taking out the coil to obtain a coil for the electromagnetic metering equipment. The invention can guarantee the precision of the coil, has neat and compact coil array, reduces flux leakage in a use process, reduces the magnetic flow discreteness and is suitable for mass industrial production of enterprises.

Description

technical field

[0001] The invention belongs to a coil forming method and device, in particular to a coil forming method and a forming mold for electromagnetic metering equipment. Background technique

[0002] The coil used for electromagnetic measuring equipment has an arc-shaped end surface with an arc surface. Due to the high precision level of the electromagnetic metering device, the higher the precision level, the higher the requirements for the electrical performance and mechanical size of the coil. Usually the preparation process of the coil is to wind the coil on the wire winding mold first, and then shape the coil after the wire has been wound. At present, coil manufacturers mostly use manual molding for the shape of the coils. This method is difficult to ensure the dimensional accuracy of the coils, and the coils are not dense and arranged irregularly. In the process of use, the magnetic flux leakage of the coil is large, and the generated magnetic flux is highly...
