[0002] The motor housing needs to be notched during the production process, so a notching die is needed. The notching die generally includes a punch and a die arranged opposite to the punch, and a notching cavity is formed on the die. When notching is required, the part to be notched is generally positioned on the die first, and then the punch is moved toward the die and passes through the part to be notched into the notching cavity. The part to be notched is notched by the punch to form a notch.
[0003] Currently, the punching of motor casings is mostly done by manual loading. Due to the problem of improper placement of the casing during manual loading, the depth of the punching grooves is out of tolerance, resulting in a high defective rate of the casing products.
