Transformer contra-angle ring press

Abstract

The invention relates to a transformer contra-angle ring press and belongs to the technical field of transformer production. The transformer contra-angle ring press comprises a pedestal, a concave dieassembly and a convex die assembly. The concave die assembly is mounted on the pedestal, and the convex die assembly is mounted above the concave die assembly. The pedestal comprises a table-board, aboss and a straight slot. The boss is arranged at the center of the table-board, the concave die assembly is mounted on the boss and is positioned, the straight slot is formed in the lateral side ofthe table-board, and a driving rod penetrating the convex die assembly is arranged in the straight slot. The concave die assembly comprises a concave die, a concave die seat, a connecting rod, a slot,a progressive slot and a center pressure sheet. A die pasting surface of a forming concave die of a contra-angle ring is arranged on the periphery of the concave die, the concave die seat is arrangedat the bottom of the concave die, an inner hole is formed in the bottom of the concave die seat, and the concave die seat is mounted on the boss through the inner hole. The convex die assembly comprises a convex die, a joint, a driving rod, an inner die core, an arc-shaped inner slot and an S-shaped inner slot. The joint is arranged on the top of the concave die, and the joint is connected to a press upward. The side wall of the concave die assembly is connected to the driving rod downward and the driving rod is in a stepped S shape integrally.

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 ring. 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 machin...
