и нижней поверхност м издели . Поскольку один из торцов трубок 9 выступает над дном канала 6, происходит разделение потоков пара и охлаждающей жидкости и обеспечиваетс  беспреп тственное поступление последней к поверхности издели . При контакте охлаждаюа ей жидкости с разогретой поверхностью издели  образуетс  слой пара и в каналах 6 по вл етс  избыточные давление , за счет которого пар устремл етс  через трубки 10 в полости 8 дл  отвода пара . Трубки 10, соедин ющие каналы 6 и полости 8 проход т через полости 5 с охлаждающей жидкостью, котора  омывает трубки 10 и охлаждает наход щийс  в них пар. Пар конденсируетс , объем его в трубках уменьшаетс , что обеспечивает посто нно пониженное давление в трубках Ю и полост х 8 по сравнению с давлением в каналах 6. За счет этого в процессе закалки происходит интенсивный отвод тепла от поверхности издели . Формула изобретени  Инструмент дл  формообразовани  с одновременной закалкой изделий из листового материала, имеющий полость дл  подачи охлаждающей среды и сообщенные с ней каналы, расположенные на рабочей поверхности инструмента, отличающийс  тем, что, с целью обеспечени  равномерного охлаждени , в нем выполнена дополнительна  полость дл  отвода пара, сообщенна  с каналами на рабочей поверхности, посредством трубок, проход щих через полость с охлаждающей средой, котора  сообщена с каналами также посредством трубок, один из торцов которых выступает над дном каналов .

Since one of the ends of the tubes 9 protrudes above the bottom of the channel 6, the vapor and coolant flows are separated and the latter is allowed to flow unhindered to the surface of the product. When the cooling liquid comes into contact with the heated surface of the product, a layer of vapor is formed and an excessive pressure appears in the channels 6, due to which the steam rushes through the tubes 10 in the cavity 8 to remove the steam. The tubes 10, the connecting channels 6 and the cavities 8, pass through the cavities 5 with coolant, which washes the tubes 10 and cools the vapor in them. The vapor condenses, its volume in the tubes decreases, which ensures a constantly reduced pressure in the tubes Yu and cavities 8 as compared to the pressure in the channels 6. Due to this, in the quenching process, intense heat is removed from the surface of the product. The invention The tool for shaping the simultaneous quenching of sheet material, having a cavity for supplying a cooling medium and communicating with it channels located on the working surface of the tool, characterized in that, in order to ensure uniform cooling, an additional cavity is provided in it for removal of steam communicated with channels on the working surface by means of tubes passing through the cavity with a cooling medium that is communicated with channels also by means of tubes, one of the ends which extends above the channel bottom.
