Stamping die and in-die automatic adhering and laminating method

Abstract

The invention discloses a stamping die, an in-die automatic adhering and laminating method, a die frame, a guide column penetrating through the die frame and a guide sleeve. The die frame comprises anupper die frame, a lower die frame, an upper pressing plate, a lower pressing plate, an upper stamping plate and a lower stamping plate which are stacked orderly from top to bottom. The guide sleevewraps the guide column, a punch of the guide column completes the in-die punching in the action process, and a special glue material is coated on the surface of an iron core material between the die frames of the die. A special heating device is adopted during blanking, and the special heating device and a cold water circulating device are controlled by a raising automatic PLC control system and are supplied with power by an automatic high-frequency special device. The special glue keeps higher activity, bonds firmly, and then is cooled rapidly by matching with the cold water circulation device, so that the self-bonding overlying is completed, the quality of the iron core is improved, the energy consumption of a motor manufactured through the iron core is reduced, the automatic capacity ofthe iron core is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to a stamping die and an automatic bonding and laminating method, in particular to a stamping die and an automatic bonding and laminating method in the mold. Background technique [0002] Motor core mold, English corresponding name: MotorCoreDie, as the core component of motor manufacturing, the iron core plays a pivotal role in the entire motor. Therefore, as an iron core mold for mass production of iron cores, it is even more critical. [0003] In the past, iron cores were stamped into loose pieces by single-punch dies or continuous dies, and then made into required thickness through rivets or welding processes--the material of iron cores is generally made of silicon steel, and the thickness of a single piece is 0.5mm, 0.35mm, 0.2mm, etc. This process is not efficient, and there are many users, so it is gradually replaced by automatic stacking riveting iron core molds. [0004] One of the current technologies is to design self-...

Problems solved by technology

[0003] In the past, iron cores were stamped into loose pieces by single-punch dies or continuous dies, and then made into required thickness through rivets or welding processes--the material of iron cores is generally made of silicon steel, and the thickness of a single piece is 0.5mm, 0.35mm, 0.2mm, etc. This process is not efficient, and there are many users, so it is gradually replaced by automatic stacking riveting iron core molds.

[0004] One of the current technologies is to design self-clamping points for punching. When producing iron cores in the mold, automatic stacking and riveting of punching sheets can be realized through self-clamping points. However, the design of self-clamping points affects the magnetic circuit of the motor, thereby affecting the overall performance of the motor.
