Description

Изобретение относитс  к обработке металлов давлением, а именно к способам правки .The invention relates to the processing of metals by pressure, in particular to methods of editing.

Известен способ правки листов путем воздействи  знакопеременным упруго-пластическим изгибом 1.There is a known method of straightening sheets by acting on alternating elastic-plastic bending 1.

Недостатком известного способа  вл етс  низкое качество правки.The disadvantage of this method is the low quality of edits.

Целью изобретени   вл етс  повышение качества правки.The aim of the invention is to improve the quality of edits.

Указанна  цель достигаетс  за счет того, что листы предварительно нагревают до температуры на 20-50°С ниже температуры перехода а --Д фазы, при этом листы располагают таким образом, что их продольные оси составл ют с осью правки угол 10-30°.This goal is achieved due to the fact that the sheets are preheated to a temperature of 20-50 ° C below the transition temperature of the a-D phase, while the sheets are arranged in such a way that their longitudinal axes form an angle of 10-30 ° with the axis of editing.

На чертеже показана схема расположени  листа при правке.The drawing shows the layout of the sheet during editing.

Лист 1 устанавливают по отношению к правильным роликам 2 таким образом, что ось листа а-а составл ет с осью правки б-б угол -р, равный 10-30°.Sheet 1 is set with respect to the correct rollers 2 in such a way that the axis of the sheet a-a is with the dressing axis bb-p angle equal to 10-30 °.

Известно, что с повышением температуры повышаетс  пластичность металла и ул чшаютс  услови  его деформации, в том числе и правки. Однако дл  высокопрочных сплавов, особенно титановых, произвольноеIt is known that as the temperature rises, the plasticity of the metal increases and the conditions for its deformation, including the changes, are improved. However, for high strength alloys, especially titanium, arbitrary

повышение температуры не позвол ет осуш ,естБл ть необходимую деформацию раст жением , при которой получаетс  высока  степень планшетности, так как титановые сплавы могут находитьс  в двух модификаци х а и ft фазы, в зависимости отthe temperature increase does not allow drying, there is a necessary deformation by stretching, at which a high degree of flatness is obtained, since titanium alloys can be in two modifications of the a and ft phases, depending on

те.мперат рного их состо ни . Наибольшего эффекта можно достичь, если нагрев вести до температуры относительной устойчивости и фазы, т. е. до температуры на 20- 50°С ниже температуры преобразовани their working conditions. The greatest effect can be achieved if the heating is conducted to a temperature of relative stability and phase, i.e., to a temperature of 20-50 ° C below the conversion temperature

U --Д фазы.U - D phase.

Фазовые превращени  в критической точке характеризуютс  значительным разупрочнением сплава, высокой пластичностью, что позвол ет при незначительных энергозатратах получить качественно выправленный лист. Нагрев до более высокой темггературь .также позвол ет повысить пластич. гь, однако при температуре выше температуры превращени  происходит резкий рост зерна, что ухудшает структуру металла и его механические свойства.Phase transformations at the critical point are characterized by a significant softening of the alloy, high plasticity, which allows, with a small amount of energy, to obtain a well-straightened sheet. Heating to a higher temperature also allows for increased ductility. However, at a temperature above the transformation temperature, a sharp grain growth occurs, which impairs the structure of the metal and its mechanical properties.

Кроме того, повысить планшетность при правке в ролико-правильных 5ашинах можно за счет раст жени  в направлении, соIn addition, it is possible to increase the flatness when editing in roller-correct 5 tires by stretching in the direction
