Forming device and method of thermoplasticity glass fiber reinforcement aluminum alloy laminate plate

Abstract

The invention discloses a forming device and method of a thermoplasticity glass fiber reinforcement aluminum alloy laminate plate. The device comprises a sealing side pressing ring (1), a discharging coil (3), a coil frame (4), bolts (5 and 11), a lower pressing plate (6), a base (7), a resistance wire (9), an upper pressing plate (10) and a hydraulic cylinder (12). The bolts (5 and 11) and the bottom of the upper pressing plate (10) are connected in a welding mode. The hydraulic cylinder (12) is fixed on the upper pressing plate (10). A working arm of the hydraulic cylinder (12) penetrates through a center hole of the upper pressing plate (10) and extends downwards. The lower end of the working arm of the hydraulic cylinder (12) is fixedly connected with the sealing side pressing ring (1). A stroke limiting block (13) is welded to the working arm. An exhaust hole (8) is formed in the side wall of the sealing side pressing ring (1). The device can preheat the laminate plate and control the cooling speed during cooling of the laminate plate, accordingly, residual heat stress caused by different contraction rates of plate pieces is released, and cracking between layers is avoided.

Description

technical field [0001] The invention belongs to the field of processing and forming of metal matrix composite materials, and in particular relates to a forming method of a thermoplastic glass fiber reinforced aluminum alloy laminate. Background technique [0002] Fiber Reinforced Metal Laminates (FRML) is a special metal matrix composite material, which is alternately laminated by metal alloy sheets and fiber / resin layups by bonding technology. Fiber laminates have excellent comprehensive properties, and glass fiber reinforced aluminum alloy laminates are currently the most used one. It not only has the advantages of high specific strength, specific stiffness, good plasticity, fracture performance and impact resistance of metal materials, but also retains the good fatigue resistance of fiber reinforced materials, and its quality is relatively light, which meets the future lightweight requirements. Direction of development. In addition, fiber-reinforced metal laminates also...

AI Technical Summary

Problems solved by technology

For example, the invention patent application number is 201310355871.0, although the forming method of a titanium alloy thin-walled shell solves the springback problem when forming a thin plate, it cannot preheat the plate without a heating device and is not suitable for thermoplastic glass fiber reinforced aluminum alloys. Processing of laminates; such as the invention patent application number of 200910062979.4, the magnesium alloy plate warm forming method can improve the formability of the material, but the heating efficiency is low and the cooling rate cannot be controlled uniformly, so when processing thermoplastic glass fiber reinforced aluminum alloy Laminates can lead to processing defects and cracking between layers
