Combined tower type thin-wall ring-shaped metal rubber part stamping die with inner reinforcement rib plates and operation method thereof

Abstract

The invention provides a combined tower type thin-wall ring-shaped metal rubber part stamping die with inner reinforcement rib plates and an operation method thereof. The stamping die comprises a cylindrical female die and a cushion block fixedly arranged on the bottom surface of the female die; a cylindrical core shaft is arranged in a female die body in a sleeving mode and is located above the cushion block; a spiral coiled metal wire blank is wound on the periphery of the cylindrical core shaft; four sunken grooves are uniformly formed in the cylinder wall of the cylindrical core shaft; a plurality of cylindrical male dies capable of moving in the axial direction of the cylindrical core shaft are sleeved between the periphery of the cylindrical core shaft and the inner wall of the female die; crossed reinforcement rib plates are fixedly arranged on the inner walls of the cylindrical male dies; the reinforcement rib plates are limited in the sunken grooves and are capable of moving along the axial direction of the cylindrical core shaft. Through the combined tower type thin-wall ring-shaped metal rubber part stamping die with the inner reinforcement rib plates, the problem that the male dies are damaged when the thin-wall ring-shaped metal rubber is stamped and molded can be effectively solved; the deformation of the male dies caused by low rigidity of the male dies in the stamping process can be avoided so as to ensure that the stamping die is not damaged under the condition that the thin-wall ring-shaped metal rubber parts are stamped and molded.

Description

Technical field: [0001] The invention relates to a stamping die for a thin-walled ring-shaped metal rubber part with an inner reinforcing rib plate and a combined tower type and a working method thereof. Background technique: [0002] The metal rubber part is a kind of elastic porous material. The metal rubber blank is put into a pre-designed stamping die, and it is cold stamped under a certain pressure, so that the inside of the metal rubber is a space network formed by interlaced metal wires. shape structure. Thin-walled ring-shaped metal rubber parts refer to ring-shaped metal rubber products with an aspect ratio greater than 30. At present, the pressure required for metal rubber cold stamping is relatively high. For metal rubber parts with small size and simple structure, one-time molding can be performed, while for metal rubber parts with large size and complex structure, it is necessary to increase the forming pressure and Step by step molding. For the mold for pr...

Problems solved by technology

For the mold for producing ring-shaped metal rubber parts with large size and large diameter-to-thickness ratio, due to the limitation of the diameter-to-thickness ratio, the external dimension of the male mold of the mold is a large-diameter thin-walled cylinder. When the molding pressure is maintained at a high level , the thin-walled cylindrical male mold will not be able to withstand high molding pressure, resulting in the failure of the metal rubber parts to be formed due to insufficient pressure or deformation of the thin-walled male mold due to excessive pressure, resulting in the failure of the metal rubber parts.
