Embodiment Construction

[0026] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0027] A stacking method for stacking accelerator cores provided by the present invention comprises the following steps:

[0028] (1) Prepare the basic steel sheet: the ultra-low carbon steel sheet rolled in the same furnace or produced in the same batch has the same or similar coercive force, and the coercive force is different More than 5% of the average value, the thickness of the ultra-low carbon steel sheet to be used is uniform, and the thickness difference between each direction and each ultra-low carbon steel sheet does not exceed 5%;

[0029] (2) Stamping: Using the die stamping method, the basic steel sheet is punched into a complete pu...

Abstract

The invention discloses a lamination sheet laminating method of an accelerator iron core and an iron core of a lamination sheet. The laminating method includes the steps of stamping, gelatinizing, laminating, extruding, solidifying and the like; the iron core of the lamination sheet includes a plurality of stamping sheets integrally formed according to the laminating method. The laminating methodhas the advantages that processing time is short, production efficiency is high, magnetic field intensity and magnetic field uniformity of the iron core of the laminating sheet can be effectively enhanced, the stability of the magnetic field and the physical properties of magnets are improved, and the size of the iron core is reduced under the equal conditions.

Description

technical field [0001] The invention relates to the technical field of manufacturing technology of iron cores in accelerator equipment, in particular to a lamination method for accelerator iron cores and a lamination iron core. Background technique [0002] An accelerator is a device that increases the velocity (kinetic energy) of charged particles. Accelerators can be used in nuclear experiments, radiation medicine, radiochemistry, manufacture of radioisotopes, non-destructive flaw detection, etc. There are many types of accelerators, including cyclotrons, linear accelerators, electrostatic accelerators, particle accelerators, and voltage doubler accelerators. [0003] The magnet is an important part of the accelerator system, which is mainly responsible for constraining the trajectory of the particle beam, so that the particle beam moves according to the route planned by the designer. [0004] The iron core in the magnet needs to be punched out of thin laminations (steel...
