Recently, the 125MN stretcher machine unit of Baowu Aluminum Technology Co., Ltd. (hereinafter referred to as the "Baowu Group") undertaken by Sino-heavymach successfully stretched the first aluminum alloy plate, marking the success of the hot test of the stretcher.
The pre-stretched aluminum alloy thick plate is widely used in aerospace, national defense, transportation and other fields. It is a necessary high quality aluminum alloy material for manufacturing large aircraft. 125MN prestretching machine unit is the key equipment of Baowu Group thick plate production line. The stretch force is up to 12500 tons. The plate can be stretched to 4.35m wide maximum, 250mm thick maximum and 38m long maximum with technical parameters reaching international advanced level. This equipment integrates multiple technical achievements accumulated by Sino-heavymach in the field of stretcher. The fixed chuck and the movable chuck adopt the new combination beam structure of the front and rear separate type, which not only can ensure the high load coefficient of the clamp mouth but also solve the technical problem of stretching the aluminum alloy short plate with super large section.
