Stamping process of electric motor silicon steel sheet

Abstract

The invention provides a stamping and forming process of silicon steel sheets for motors. The steps are as follows: firstly, when the loading pick-up arm in the loading and unloading mechanism is rotated to cooperate with the feeding mechanism, the magnet on the loading picking arm will press the silicon steel sheet supplied by the feeding mechanism. The semi-finished silicon steel sheet is picked up by suction, and then, when the loading pick-up arm will continue to rotate to match the punch workbench, the magnet on the load pick-up arm will attract and release the picked-up silicon steel sheet semi-finished product and place it on the punch workbench; then, the upper part of the punch press The mold and the lower mold cooperate with each other to complete the blanking of the semi-finished silicon steel sheet; finally, when the unloading pick-up arm in the loading and unloading mechanism rotates to match the punch workbench, the magnet on the unload pick-up arm completes punching on the punch workbench The finished silicon steel sheets are picked up by suction, and then, when the unloading pick-up arm continues to rotate to cooperate with the receiving mechanism, the magnet processing on the unloading picking arm attracts the picked-up finished silicon steel sheets to be released and placed on the receiving mechanism.

Description

technical field [0001] The invention relates to the technical field of punch processing, in particular to a punch forming process of a silicon steel sheet for a motor. Background technique [0002] The iron core is one of the effective parts of the motor. The manufacturing process of the iron core has a great influence on the operating performance of the motor. The iron core is often made of soft magnetic material silicon steel sheet after punching and pressing the punched silicon steel sheet. Currently , the punching operation of silicon steel sheets is often handled by manual punching machines. The specific performance is that the operator manually installs the semi-finished silicon steel sheet on the lower die of the punching machine, and then starts the punching machine. The main motor of the punching machine drives the slider through a series of transmissions. Moving up and down, the slider drives the upper mold to move downward synchronously and cooperates with the low...

[0002] The iron core is one of the effective parts of the motor. The manufacturing process of the iron core has a great influence on the operating performance of the motor. The iron core is often made of soft magnetic material silicon steel sheet after punching and pressing the punched silicon steel sheet. Currently , the punching operation of silicon steel sheets is often handled by manual punching machines. The specific performance is that the operator manually installs the semi-finished silicon steel sheet on the lower die of the punching machine, and then starts the punching machine. The main motor of the punching machine drives the slider through a series of transmissions. Moving up and down, the slider drives the upper mold to move downward synchronously and cooperates with the lower mold to complete the blanking process of the semi-finished silicon steel sheet. Finally, the operator takes out the finished silicon steel sheet from the lower mold to complete the blanking of a silicon steel sheet. The labor intensity of the operator is high, the blanking efficiency is low, and the manual loading and unloading of the operator is dangerous to a certain extent. Therefore, it is necessary for the present invention to provide a kind of ingenious structure and simple principle, which can assist the punching machine to carry out the electric motor silicon steel sheet. Automatic loading and unloading, which can greatly improve the punching efficiency of silicon steel sheets. The automatic loading and unloading method of punching motor silicon steel sheets
