Hot stamping and forming production line for aluminum alloy sheet materials

Abstract

The invention discloses a hot stamping and forming production line for aluminum alloy sheet materials. The hot stamping and forming production line comprises a destacker, a sprayer, heating furnaces, a pressing machine, a plate chain conveyor and an aging furnace, wherein the destacker is used for conveying the sheet materials to a feeding position to hand over to a manipulator; the sprayer is used for conducting lubricant spraying on the two surfaces of each sheet material; the heating furnaces are used for conducting heating and heat preservation on each sheet material with the two surfaces sprayed with lubricant; the pressing machine is used for conducting stamping and forming on the sheet materials subjected to solid solution treatment; the plate chain conveyor is used for receiving the stamped parts; and the aging furnace is used for conducting aging treatment on the parts. Each heating furnace comprises a feeding area, a hearth and a discharging area which are sequentially arranged, wherein the hearth is internally provided with at least one heating area and at least one heat preservation area; each layer of the hearth is provided with at least two sheet materials fed sequentially; heating of the interior of the hearth is in a nozzle mode; the feeding area and the discharging area are both rolling type lifting platforms; the heating area and the heat preservation area are both provided with multi-layer bi-directional rolling platforms; and the lifting height of the rolling type lifting platforms and the height of each layer of the multi-layer bi-directional rolling platforms are the same. According to the hot stamping and forming production line for the aluminum alloy sheet materials, hot stamping and forming can be conducted on the aluminum alloy sheet materials efficiently.

Description

technical field [0001] The invention relates to the field of hot stamping, in particular to a hot stamping production line for aluminum alloy plates. Background technique [0002] Hot stamping of high-strength aluminum alloy sheet is a brand-new forming manufacturing process, namely HFQ process. It is characterized in that the solution treatment of the aluminum alloy is completed at the same time as the stamping forming. The solution treatment of the high-strength aluminum alloy sheet in the hot stamping process requires heating the billet to 450-550°C and holding it for a certain period of time. Then the blank is quickly taken out of the heating furnace and sent to the mold for stamping and pressure-holding quenching. The prepared aluminum alloy parts are artificially aged or naturally aged according to the strengthening mechanism of the alloy used to obtain high-strength parts. [0003] At present, the heating furnace of aluminum alloy sheet commonly used in the market ...

AI Technical Summary

Problems solved by technology

If the current multi-layer box-type heating furnace is used for solid-solution heating of aluminum alloy plates, the production cycle is only 0.6 times / minute, and the stamping production efficiency is low, which is also difficult to meet the actual production needs.
