Description

TECHNICAL FIELD

[0001] The present application relates to the field of laminated core cutting for transformer, and particularly relates to a cutting device for processing laminated core for transformer. BACKGROUND

[0002] A transformer is a device for changing the voltage of alternating current by using the principle of electromagnetic induction, and main components are primary coil, secondary coil and core (magnetic core). Main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer) and the like. Transformers can be divided into distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers, box-type transformer test transformers, phase transformer, high-current transformers, excitation transformers and the like according to use.

[0003] Now, when the laminated core for transformer is put into cutting use, a part of the core will be cut. At present, the existing laminated core cutting device for transformer generally places the core to be cut on an operation table, then fixes the core, and cuts the core by hand. This operation may cause the position of the cutter to deviate when cutting the core, resulting in inconsistent cutting size and excessive waste, thereby reducing work efficiency. Since the laminated core for transformer needs to be cut into many iron sheets, one worker cannot complete the cutting work, which will cause time-consuming and laborious situation, and more seriously, the cutter may scratch the worker. Some assembly line type core cutting devices on the market are fully automated, but they are large in size, expensive in cost, and high in maintenance cost, which is not suitable for small companies to purchase and use. In addition, the mechanical equipment consumes more electricity during operation, and the formed core needs to be collected and arranged neatly by human beings.
