Special transformer coil winding device

Abstract

The invention discloses a special transformer coil winding device which is characterized by comprising a rotary mandrel. The rotary mandrel is horizontally arranged, a forming block which can axially move along the mandrel sleeves the mandrel, a wound copper wire can be guided by the forming block to be wound on the mandrel, an arc-shaped guide groove for accommodating the copper wire is formed in the forming block, an opening in the arc-shaped guide groove faces the mandrel, spiral rising angles of the guide groove and the mandrel are equal to spiral angles of a wound coil, the corresponding distance from the rear side surface of the guide groove to the front end surface of the forming block is equal to the pitch of the wound coil, a connecting arm which outwardly extends is arranged on the forming block, support pulleys which are arranged on the ground are fixed onto the connecting arm, and rollers are mounted at the bottoms of the support pulleys. The special transformer coil winding device has the advantages that the special transformer coil winding device is compact in structure, low in manufacturing cost and convenient to use and is small, the coil can be automatically wound, the labor cost can be saved, and the production efficiency and the product quality can be improved; the special transformer coil winding device is simple in structure and smart in design and is functionally reliable, workers can easily operate the special transformer coil winding device, and the like.

Description

technical field [0001] The invention relates to an automatic winding and forming device for special transformer coils. Background technique [0002] Transformer coil is an important performance index of transformer performance. The continuity, integrity and consistency of coil winding are important technical guarantees to ensure coil performance. Since the coils of special transformers are mostly irregular and the coil shapes of various types of transformers are different, such as figure 1 As shown, most manufacturers adopt the method of simple tooling combined with manual winding and molding. Its technical characteristics are strong flexibility and relatively low production cost. The disadvantage is that the consistency of winding is poor. Poor continuity, large changes in the cross-sectional area of ​​the wire, etc., make the technical parameters of each coil poor in consistency and unstable in technical performance.
