Description

Cutting device for manufacturing insulators for transformers}

The present invention relates to a cutting device for manufacturing insulators for transformers, and more specifically, to a cutting device for manufacturing insulators for transformers that can reduce the loss rate of raw materials.

Typically, insulators for transformers are manufactured using wood or polygonal cellulose resin (pulp) with guaranteed insulating performance.

Insulators for transformers are manufactured by cutting raw materials and then performing shape processing such as NC processing and hole processing.

Wood or polygonal cellulose resin (pulp), which are used as raw materials for transformer insulators, are raw materials with guaranteed insulating properties, so relatively expensive imported products are used in most cases compared to ordinary wood or vertical wood.

For this reason, it is important to reduce the loss rate of raw materials and cut them effectively.

In addition, there is a need to solve the problem of by-products such as sawdust generated while cutting raw materials scattering and loading on the raw materials, interfering with cutting.
