Technical Field

The invention belongs to the technical field of dies, and particularly relates to a compressor motor shell side punching die.

Background

The existing compressor motor shell is finished by multi-step stretching, rotary cutting and side punching, because the compressor motor shell is an oval full-curved-surface part, after multi-step stretching forming, the step of the opening part of the compressor motor shell is an oval curved surface, the opening part is uneven, a plane which needs to be used cannot be effectively determined to meet requirements, the end surface is flat after rotary cutting, the shape and the size of the oval curved surface are determined to meet requirements, but in the side punching and upsetting process, because the compressor motor shell is influenced by very large side punching force and blanking force, the size of the matching surface of the oval curved surface is changed, and the size and the matching requirements cannot be met.

No matter how to adjust the previous stretching process, the rotary cutting process cannot meet the requirement of the precision of the elliptical assembly dimension, the side punching tool is continuously improved, the pressing force is improved, the sequence of the slide block action and the fit of the concave die surface cannot meet the requirement of the dimension of the elliptical assembly surface.

Therefore, the size of the elliptic curved surface of the shell of the motor of the compressor cannot be ensured in the side punching process in the prior art, so that the defective products in the punching process are very high, and the fitting pieces cannot be effectively matched in the subsequent automatic production line assembling process, so that the welding is problematic, the whole motor assembly is scrapped, and irrecoverable great economic loss and delivery delay are caused.
