Description

TECHNICAL FIELD

[0001] The utility model relates to the field of machining equipment, especially to a swing head cutting mechanism. BACKGROUND

[0002] The transformer has an iron core inside, which can be understood as a tightly wound coil. A lot of turns of conductive bodies are combined together at a position perpendicular to each other, playing a role of enhancing the magnetic field, which is called winding. The transformer core is made of iron core material, and silicon steel sheet and silicon steel sheet are common types of core materials inside the transformer. Silicon steel sheet, commonly known as cold-rolled silicon steel sheet, is a steel product whose main element is silicon, with high magnetic permeability and low loss, and is one of the ideal materials for manufacturing electromagnetic equipment such as transformers and motors. Silicon steel sheet, also known as enhanced silicon steel sheet, is a kind of silicon steel sheet with a small amount of molybdenum, niobium and other elements added to it. It has good magnetic properties and low loss, and overcomes the shortcomings of silicon steel sheet in the magnetic hysteresis loop. It is widely used in the field of motors and other fields. During production, the steel sheet needs to be cut and modified to adapt to the manufacture of transformers of different sizes. Because the two ends of the steel sheet are inclined edges facing different directions, a swing head cutting structure is usually needed for processing.

[0003] The patent document with application number 202410038981.2 discloses a metal sheet shearing device, which includes an upper feeding assembly, a first shearing assembly, an intermediate feeding assembly, a second shearing assembly and a stacking assembly arranged in sequence along the length direction of the sheet. The upper feeding assembly is used for feeding the sheet. The first shearing assembly can perform edge notching and / or fixed hole shearing operation on the sheet. The intermediate feeding assembly continues to feed the sheet with edge notching and / or fixed hole shearing operation to the second shearing assembly. The second shearing assembly shears the sheet to obtain parts with edge notching and / or fixed hole. The third shearing drive unit 423 in the device can drive the fourth cutter 422 and the third cutter 421 to close together, thereby shearing and cutting the sheet to obtain parts. The fourth shearing drive unit 43 can drive the shearing frame body 41 to rotate around the vertical axis, thereby shearing to obtain two inclined edges of the trapezoidal part. This working mode is low in efficiency, and the gear gap in the reduction box affects the action accuracy of the cutter. Therefore, how to develop a new type of swing head cutting mechanism has become a problem to be solved by the technical personnel in the field. UTILITY MODEL CONTENTS
