Large-scale Transformer Coil Manufacturing Accompanied Pneumatic Wire Tensioning Device

Abstract

The invention relates to a following-type pneumatic tensioning device used in the manufacturing process of a large transformer coil. The following type pneumatic wire tensioning device comprises a base, a carriage which can move right and left is arranged on the base, and a rack which can swing back and form in the advancing direction of wires is hinged to the carriage. A wire arranging mechanism, a wire dividing mechanism and a pneumatic tensioning mechanism are arranged on the rack in sequence in the advancing direction of the wires, the wire arranging mechanism is used for arranging the wires in a row, the wire dividing mechanism is used for dividing the wire row and the pneumatic tensioning mechanism is used for tensioning a plurality of wire layers. The pneumatic tensioning mechanism comprises a cylinder, a pressing block and a tensioner, the cylinder drives the pressing block to press the tensioner or to enable the tensioner to reset, and the wires in the tensioner are loosened when the tensioner resets. The following-type pneumatic tensioning device used in the manufacturing process of the large transformer coil is reasonable in design, low in manufacturing cost and convenient to use. The tensioning force can be well regulated and controlled, the wires are not damaged, the efficiency of winding the large-capacity transformer coil can be improved by 2-3 times when the following-type pneumatic tensioning device is matched with a large-scale horizontal type winder, and the size and the mechanical performance of the coils wound through the tensioning device are guaranteed to meet quality requirements.

Description

technical field [0001] The invention relates to a large-scale transformer coil manufacturing accompanying pneumatic wire tensioning device. Background technique [0002] When the transformer coil is wound, in order to ensure that the coil is tightly wound and improve the mechanical strength of the coil, there must be a wire tensioning device to apply and maintain a certain tension on the wire for tension. At present, there are mainly two types of existing wire tensioning devices. The first type is the spring-pressed brake type and the pneumatic brake friction disc type, which are mainly used for horizontal winding of small and medium-sized transformer coils; the second type is the pneumatic pressure type. The clamping plate type is mainly used for vertical winding of large coils; for horizontal winding of large coils, due to the large number of wires and the large height of the coil, the use of ordinary tensioning devices cannot fully meet the winding requirements.
