Wire-falling machine

Abstract

The invention relates to a wire-falling machine of mechanical production equipment for embedding a motor iron core into a coil, comprising a rack and a mold frame, wherein the rack consists of a working platform and a rack guide column arranged on the working platform; an upper hydraulic cylinder is arranged on a cross beam of the upper part of the rack guide column; an upper mold push plate is arranged on a hydraulic output shaft of the upper hydraulic cylinder; the working platform is provided with the mold frame which is provided with coil guide strips; the two sides of the coil guide strip are provided with thrust columns; the rack guide column is arranged between the mold frame and the working platform and is provided with an elastic piece; the center of the coil guide strip is provided with a wire head push pipe; the bottom end of the wire head push pipe is fixed on the working platform, and the top end thereof is provided with a wire head; the working platform is provided with a lower hydraulic cylinder; and a groove cover piece push strip is installed on a lower hydraulic output shaft of the lower hydraulic cylinder and extends between the coil guide strips. The wire-falling machine has the advantages of high production efficiency, low production cost and hard breaking of the coil.

Description

technical field [0001] The invention relates to the field of mechanical production equipment in which the iron core of a motor is embedded in a coil, in particular to a wire dropping machine. Background technique [0002] During the winding process of the stator coil of the motor, the stator drop-off machine is a mechanical device that feeds the enameled wire and insulating paper into the stator core, such as the invention name disclosed in the national patent: the drop-off mold of the stator drop-off machine, and the application number is: 200610097554.3 , it is clearly shown from the accompanying drawings and instructions that its structure is as follows: a flange plate, one end of the flange plate is connected with a guide bar and a storage bar on the outer ring of the guide bar, and the outside of the storage bar has a storage bar installed on the flange plate Cover, the other end of the flange plate is installed with a material cylinder seat, the storage cylinder is ins...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned structure has disadvantages: 1. Squeeze the coil into the wire slot on the motor core, because the coil is forced into the coil slot when entering, a large number of coils will be broken, in order to prevent the coil from being squeezed into When the wire slot is broken, thick coils and iron cores with wider slot slots are used to increase the number of coil turns to compensate for the loss of magnetic energy caused by the wide slot, resulting in high manufacturing costs; 2. This structure can only be used relatively Thicker coils, so the scope of application is relatively narrow, which is not conducive to market development needs

[0004] There is also a manual method for motor drop-off. Although smaller coils and iron cores with narrow slots and a wide range of applications can be used, manual drop-off has the disadvantage of low efficiency, and often requires certain skills. Skilled skilled workers, in the current situation of relatively large personnel turnover, it is relatively difficult for enterprises to retain employees for a long time, which seriously hinders production progress
