Large water-cooling die for thermal forming of high-strength steel plate

Abstract

The invention discloses a large water-cooling die for thermal forming of a high-strength steel plate. The large water-cooling die comprises an upper die frame, a lower die frame, an upper die insert,a lower die insert, guide devices, a limiting block, a water-cooling device and a slideway type feeding and discharging device, wherein the guide devices are mounted between the upper die frame and the lower die frame, are positioned on the two sides in front of the upper die insert and the lower die insert and are used for guiding plates conveyed into the large water-cooling die; the slideway type feeding and discharging device is mounted in the lower die insert; the limiting block is installed on the lower die insert and located behind the slideway type feeding and discharging device; and the cooling device is communicated with the slideway type feeding and discharging device. Thus, hot plates can be stably, accurately and quickly conveyed into a die for a long distance, and large platescan be conveniently cooled.

Description

technical field [0001] The invention belongs to the technical field of thermoforming of high-strength steel plates, in particular to a large-scale water-cooled mold for thermoforming of high-strength steel plates, and is especially suitable for processing steel plates used in commercial vehicles. Background technique [0002] The current thermoforming production line uses a cantilever feeding device to feed the heated sheet into the mold, and the length of the steel plate parts used in commercial vehicles is more than 4 meters, and the longest can reach more than 10 meters. Due to the steel plate thermoforming process When using longitudinal feeding, the red-hot sheet should be sent into a mold with a length of more than 10 meters, which cannot be realized with a cantilever feeding device. In addition, commercial vehicles mostly use thick steel plates of 2-16 mm, so cooling and quenching fluids face great difficulties. Therefore urgently need a kind of large-scale water-coo...

Problems solved by technology

[0002] The current thermoforming production line uses a cantilever feeding device to feed the heated sheet into the mold, and the length of the steel plate parts used in commercial vehicles is more than 4 meters, and the longest can reach more than 10 meters. Due to the steel plate thermoforming process When using vertical feeding, the red-hot sheet must be fed into a mold with a length of more than 10 meters, which cannot be realized with a cantilever feeding device.

In addition, commercial vehicles mostly use thick steel plates of 2-16mm, so it is very difficult to cool the quenching fluid
