Description

Technical Field

[0001] The present application relates to the field of stator processing, and in particular to a riveting and wire cutting device for stator terminals. Background Art

[0002] During motor manufacturing, the copper wires on the stator need to be docked with the connection terminals to ensure proper connection. The copper wires and terminals are typically connected by welding or riveting. Welding is relatively expensive, unsafe, and can easily damage the coils during processing. Riveting is relatively safe and quick, or a stamping method can be used to force the terminals to grip the copper wires to achieve the desired connection. Traditional riveting is often done manually, using a hammer to secure the copper wires. Because the copper wire dimensions cannot be determined during fixation, the ends of the wires are often exposed, which not only affects motor performance but also creates an unsightly appearance and reduces motor quality.
