An integrated device and method for forming and connecting metal edge wrapping of blades with variable thickness

Abstract

The invention discloses a forming and connecting integrated device and method for metal wrapping of blades with variable thickness, which comprises an upper mold, a binder ring and a lower mold, the binder ring is located between the upper mold and the lower mold; A forming cavity capable of forming metal edging between them; the upper mold is provided with an upper mold cavity gas channel and a glue injection channel, and the lower mold is provided with a radial gas channel, a lower mold cavity gas channel and several contact thermocouples. The cavity gas channel, the radial gas channel and the lower cavity gas channel are respectively connected to the pressure controller through the pipeline, the pressure controller is connected to the high-pressure gas cylinder, the glue injection channel is connected to the glue injection pump, and the glue injection pump is connected to the glue storage tank ; Several ultrasonic vibration probes are also arranged on the upper mold. The forming and connecting integrated device and method of the blade metal edging with variable thickness of the present invention improve the forming quality and efficiency of the blade metal edging.

Description

Technical field

[0001] The present invention relates to the field of material forming technology, in particular to a variable thickness blade metal hemming forming connection integrated device and method. Background

[0002] At present, the preparation of blade hemming metal is mostly cast or machined, but the casting process will make the thin-walled part of the blade hemming dissatisfied, poor casting quality, and low dimensional accuracy, while the problem of machining is that the material utilization rate is low, the metal streamline is broken, and the service performance is poor. The use of stamping or rolling and other plastic forming and then the use of gluing is also a common method of leaf edge, but the production steps are complex, the forming efficiency is low, and then gluing after forming will lead to geometric accuracy distortion problems; barometric forming has better forming efficiency than stamping rolling, but the commonly used barometric forming is mostly unil...
