Automatic forming machine and method for transformer enameled wire U-shaped coils

Abstract

The invention provides an automatic forming machine and method for a transformer enameled wire U-shaped coil, and the method comprises the steps: fixing a feeding guide structure for the feeding guideof a copper wire raw material on the front side wall of a main case, and arranging a traction power device for the traction of a copper wire at a station behind the feeding guide structure; the output end of the traction power device is provided with a discharging guide structure used for guiding straightened copper wires, the output end of the discharging guide structure is provided with a cutting-off mechanism used for cutting off the copper wires, and a rear guide plate structure is arranged on a station behind the cutting-off mechanism; the telescopic pressing mechanism used for pressingthe copper wire is arranged behind the rear guide plate structure, and a bending mechanism is arranged at the station behind the telescopic pressing mechanism. A conventional manual operation mode isreplaced, and the working efficiency is greatly improved.

Description

Technical field

[0001] The invention relates to the field of electronic component processing equipment, in particular to an automatic forming machine and method for a U-shaped coil of enameled wire of a transformer. Background technique

[0002] In the production process of small transformer electronic components, it is necessary to wind the enameled wire. The internal coil is a U-shaped coil, which is made of thick copper wire, and the distance between the two pins and The accuracy of the bending angle is high.

[0003] At present, the manual bending method is usually used for the bending of U-shaped coils. The manual bending method is less efficient and the labor intensity of the operators is high. During the manual bending process, it is impossible to guarantee the contact between the pins. The spacing accuracy is required, and the bending angle cannot be guaranteed, and the quality of the product cannot be guaranteed. Summary of the invention
