Rapid demolding method after press quenching of synchronous ring and synchronous ring press quenching device thereof

Abstract

The invention discloses a rapid demolding method for a synchronous ring after pressure quenching and a synchronous ring pressure quenching device thereof. The synchronous ring pressure quenching device comprises a lower mold, an upper mold and a quenching core mold, the upper die and the lower die are oppositely arranged, the upper die is installed on the upper pressing die connecting base, a core die is arranged at the bottom of the upper die, the upper die is provided with a cooling water channel, an inductor electrically connected with a power supply transformer is arranged on the periphery of the end, close to the core die, of the upper die, and a water spraying ring is arranged on the periphery of the core die and comprises an inner ring and an outer ring. The inner ring and the outer ring form an annular quenching spraying cavity, and the water spraying flow speed and the water spraying time of the water spraying ring are controlled by a controller. A lower die, an upper die and a quenching core die are arranged; the inductor is arranged on the periphery of the end, close to the core mold, of the upper mold, so that a product on the quenched core mold is preheated, demolding is facilitated, and the mold and a workpiece cannot be strained.

Description

technical field [0001] The invention belongs to the technical field of industrial machinery, and more specifically relates to a quick demoulding method for a synchronous ring after press quenching and a synchronous ring press quenching device. Background technique [0002] The synchronizer ring is an important part of the synchronizer. The function of the synchronizer is to ensure smooth shifting without impact and reduce shifting force. In the manufacturing process of the synchronous ring, pressure quenching is an essential process. Due to the need for heat treatment, the synchronous ring is greatly deformed. [0003] The existing synchronous ring quenching tooling includes a lower mold, an upper mold and a quenching mandrel. When working, the workpiece is placed on the quenching mandrel, the lower mold and the upper mold are clamped, and then quenched. However, after quenching, the synchronous ring workpiece will be fixed on the quenching mandrel. On the mandrel, it is no...

In the manufacturing process of the synchronous ring, pressure quenching is an essential process. Due to the need for heat treatment, the synchronous ring is greatly deformed

[0003] The existing synchronous ring quenching tooling includes a lower mold, an upper mold and a quenching mandrel. When working, the workpiece is placed on the quenching mandrel, the lower mold and the upper mold are clamped, and then quenched. However, after quenching, the synchronous ring workpiece will be fixed on the quenching mandrel. On the mandrel, it is not easy to remove, which will affect the processing of subsequent workpieces and affect the production progress, and even to pull out the workpiece will cause certain damage to the mandrel and workpiece, affecting product quality
