A Transformer Contra-Angle Ring Compression Machine

Abstract

A transformer dihedral ring pressing machine, which belongs to the technical field of transformer production, includes a base, a die assembly and a punch assembly, the die assembly is installed on the base, and the punch assembly is installed on the base of the die assembly above. The base includes a table top, a boss and a through groove. There is a boss in the center of the table. the drive rod. Die assembly includes die, die seat, connecting rod, card slot, progressive groove and center pressure piece, the periphery of the die is the molding surface of the forming die with dihedral ring, the bottom of the die has a die seat, and the die The bottom of the die base has an inner hole, and the die base is installed on the boss through the inner hole. The punch assembly includes a punch, a joint, a drive rod, an inner mold core, an arc-shaped inner groove and an S-shaped inner groove. There is a joint on the top of the die, and the joint connects upward to the press. The side wall of the die assembly is downwardly connected to the driving rod, and the driving rod is in a stepped S shape as a whole.

Description

technical field [0001] The invention belongs to the technical field of transformer production, in particular to a transformer dihedral ring pressing machine. Background technique [0002] A large number of insulating parts are used in the production of transformers. Among them, the more common and important one is the angle ring. The angle ring is divided into two types: positive angle ring and anti-angle ring. outer circle. The currently commonly used angle ring forming device is the mold pressing method, but the current mold is usually simple in design, especially the punch, it is difficult to realize the progressive forming of the angle ring, and, in the pressing process, the die is usually relatively static, and the angle The ring wool is also relatively static, and the conditioned wool may stick to the downward moving punch, causing the corner ring to be torn. Contents of the invention [0003] The present invention provides a transformer dihedral ring pressing mach...
