Pole core assembly technique for punching quadrant iron type through-flow generator

Abstract

The invention provides an assembly technology of a pole core of a punching square steel type through-flow generator. The pole core is compressed in a frame hydraulic pressure hold-down gear with a hydraulic pressure jack which can reset; fabrication holes are arranged on the punching square steel and a damping bar by the hold-down gear and an iron core is jacked into the fabrication holes which are assembled on the iron core. The punching square steel and an end bevel of a pressing board of the pole core are welded 20 percent. After the end bevel is cooled to room temperature, oil pressure is discharged so as to lead the pole core to be lifted out from the hold-down gear, then the full welding is conducted three times respectively on the end bevel. The assembly technology in the invention has the advantages of reasonable and concise flow, convenient installation and operation, high ratio of the high-class products and high production efficiency and the like; and the frame hydraulic pressure hold-down gear has the advantages of compact shape structure, simple and easy operation and low manufacturing cost, etc.

Description

technical field [0001] The invention relates to a process method for assembling a magnetic pole core of a through-center square steel type tubular generator. Background technique [0002] In the past, the structure of the magnetic pole core of the tubular flow unit was riveted by shoe parts and assembled and welded with the magnetic pole square steel as a whole. less efficient. The magnetic pole core of the through-center square steel type tubular generator solves this technical problem. Its structural features: the assembly gap between the through-center square steel and the magnetic pole punching piece is small, and it is welded with the groove of the magnetic pole pressure plate at both ends of the iron core, ensuring that the iron core Form and position tolerance requirements. There are several connecting square holes stacked on the tail of the iron core and the magnetic yoke, and several connecting screw holes on the core square are located in the middle of the connec...

AI Technical Summary

Problems solved by technology

According to the traditional double-rod tensioner compression device to compress the iron core and the magnetic pole punching shoe with the boot facing upwards, it is impossible to directly adjust and measure the size and position of the square hole at the end of the iron core, and it is impossible to ensure that the square hole just goes through the core. The position of the screw hole and the square hole on the iron core

The pressure center of the double-rod tensioner compression device does not coincide with the center of gravity of the magnetic pole punching pieces, the pressure between the core pieces is uneven, the shape and position tolerance of the magnetic pole core is poor, and the center-through square steel and damping strips are difficult to assemble on the core. The external structure and size of the double-rod tensioner compression device are relatively large, and the manufacturing cost is relatively high
