Problems solved by technology

The disadvantage of this kind of structural product is that the structure is more complicated. The annular coil groove can only be processed after the three parts are connected (bonded or welded). The connection structure is poor in firmness, and the bonding or welding structure is easily damaged during processing. Low efficiency and high defective rate

Abstract

The invention provides a processing method of a novel combined high-speed electromagnet iron core. The novel combined high-speed electromagnet iron core consists of a plurality of silicon steel sheets and an iron core seat, and is characterized by comprising the following steps that a, the iron core seat is processed by a conventional method; b, rectangular silicon steel sheets are cut; c, the rectangular silicon steel sheets are embedded into an iron core combining element blank element of the iron core seat, and the iron core combining element blank element is provided with a pair of notches; d, the blank element is welded at the notch part through argon arc welding; e, an annular coil groove is cut and processed in the end surface. The processing method has the advantages that the structure is simple, the processing process is simple, the production efficiency is high, the processing cost is low, in the electromagnet assembly process in the subsequent work procedure, when the iron core combining element is assembled and bonded with a case, the notches naturally formed at the two sides form an epoxy glue filling opening, the filling is convenient and smooth, and the glue filling quality is guaranteed.

Description

technical field [0001] The invention relates to a processing method for an electromagnet structure, in particular to a processing method for a combined iron core structure of a high-speed electromagnet. Background technique [0002] High-speed electromagnets are key control actuators for control systems such as electronically controlled fuel injection systems for diesel engines. In the diesel engine electronically controlled fuel injection system, its function is to execute the system ECU command, control the pump valve to close, and complete the precise fuel injection. The electromagnet is required to have the characteristics of fast response speed, low eddy current loss, large electromagnetic attraction force, and small size. [0003] The Chinese utility model patent No. 20082063803.1 discloses a combined high-speed electromagnet iron core, which includes silicon steel laminates, a circular iron core seat, and a non-magnetic metal jacket. Assembled body, an annular coil ...
