Damping type angle ring pressing machine

Abstract

The invention discloses a damping type angle ring pressing machine and belongs to the field of transformer production. The damping type angle ring pressing machine comprises a base, a female mold assembly, a male mold assembly and a driving assembly. The female mold assembly is mounted on the base. The male mold assembly is located above the female mold assembly. The driving assembly is mounted onthe base. The base comprises a table board, a round hole and a through hole. The table board is provided with the round hole. The side portion of the round hole is provided with the through hole. Thefemale mold assembly comprises a female mold, a female mold seat, a molding hole, a gradually-advancing groove and a side portion ring. The bottom of the female mold is provided with the female moldseat. The center of the female mold is provided with the molding hole penetrating the female mold and the female mold seat. The outer edge of the top face of the female mold is provided with the gradually-advancing groove. The side portion ring is mounted on the gradually-advancing groove. The male mold assembly comprises a male mold, a male mold profile and a main joint. The bottom of the male mold is provided with the male mold profile. The driving assembly comprises cross bars, a joint, a crank, a rotating disc, a boss, springs, adjustment nuts and a connecting rod. The middles of the crossbars are connected with the connecting rod. The connecting rod is mounted on the female mold and drives the female mold to move. The cross bars at the two sides of the connecting rod are each provided with the corresponding spring. Each adjustment nut is mounted at the outer side of the corresponding spring.

Description

technical field [0001] The invention belongs to the technical field of transformer production, in particular to a damping type corner 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 damping type corner ring pressing machin...
