AI Technical Summary

Problems solved by technology

The deficiencies in the processing of the impeller by the impeller rolling riveting device on the existing metal fan impeller forming machine are: 1. When the impeller is inserted into the rolling riveting mandrel, the long axis is easy to bend and deform during processing, and the radial runout of the impeller after riveting is large, and the reject rate is high , the product quality cannot be guaranteed; the degree of automation is low, manual loading and unloading is required, and the processing efficiency is low

Abstract

The invention relates to processing equipment for metal cross-flow fan impellers, in particular to an impeller roll-riveting device mounted on a metal fan impeller forming machine, which comprises a roll-riveting bottom plate, a roll-riveting frame, an upper roll-riveting mechanism, a lower roll-riveting mechanism and a lower roller separation mechanism. The impeller roll-riveting device mounted on the metal fan impeller forming machine has the advantages of novel structure, good product coaxiality, high quality, low rejection rate, high automation degree and high processing efficiency.

Description

technical field [0001] The invention relates to a processing equipment for a metal cross-flow fan impeller. Background technique [0002] The existing rolling riveting equipment for metal cross-flow fan impellers mainly consists of a fixing mechanism and a rolling riveting tool. When in use, the impeller is first inserted into the rolling riveting mandrel of the fixing mechanism by hand, and the two ends of the impeller are fixed and rotated quickly, and then The outer edge of the center plate is squeezed with a roll riveting tool through the feeding of the rolling riveting tool, so that the center plate and the blade are tightly fixed and riveted to form, and finally the formed impeller is taken out by hand. The deficiencies in the processing of the impeller by the impeller rolling riveting device on the existing metal fan impeller forming machine are: 1. When the impeller is inserted into the rolling riveting mandrel, the long axis is easy to bend and deform during process...
