An automatic winding machine for discharge coil

Abstract

The invention discloses an automatic winding machine used for a discharge coil. The automatic winding machine is a winding device used for a discharge coil of a core component of an electromagnetic forming device in the fields of aviation, aerospace and automobiles; the instantaneous feed speed of a copper belt can be synchronously fed back to a servomotor of a winding plate, and glass fiber cloth is controlled to be uniformly wound around the surface of the copper belt, so that the winding quality of the discharge coil is improved. A driving mechanism provides power for the whole system. A clamping mechanism ensures that the copper belt is in a straight and tensioned state during a winding process, so that uniform feeding of the copper belt is facilitated. A glue scraping and coating assembly is used for finishing impregnation glue-coating of the copper belt and the glass fiber cloth, as well as scraping of residual insulated resin glue on the surfaces of the copper belt and the glass fiber cloth. A rotational speed control mechanism realizes synchronous adjustment of the rotational speed of the belt winding plate. An electromagnetic clutch enables a coil winding mould to drive a main shaft to rotate and stop for preventing the rotation and stop of the motor from inertially influencing a coil winding effect. A counting sensor and a limiting switch control a coil winding number and a coil winding outer diameter to ensure coil winding consistency; the service life of the discharge coil is prolonged.

Description

technical field [0001] The invention relates to the technical field of process equipment structure design and manufacture, in particular to an automatic winding machine for discharge coils. Background technique [0002] Electromagnetic forming equipment includes electromagnetic riveting equipment, stress wave installation equipment and electromagnetic forming machines. Electromagnetic forming equipment has been widely used in aerospace and home appliance manufacturing fields. The discharge coil is the key component of the electromagnetic riveting forming equipment. One of the key technologies in the winding process of the discharge coil is the control of the feeding speed of the copper strip and the winding speed of the insulating cloth. As the outer diameter of the coil increases, its winding speed also needs to be changed accordingly. [0003] Invention patent 200810232458.4 discloses "a manufacturing method of electromagnetic riveting gun discharge coil". The manufactu...
