Abstract

1. Способ термопластического упрочнения деталей, заключающийся в том, что детали нагревают до температур ниже фазовых переходов с последующим охлаждением под давлением не ниже 8 атм, отличающийся тем, что наружные, внутренние поверхности, канал и отверстия деталей упрочняются одновременно потоком охлаждающей жидкости, который регулируют так, чтобы теплоотдача со всех поверхностей деталей была одинаковой. ! 2. Установка для термопластического упрочнения деталей, содержащая зону нагрева, зону охлаждения, емкость с жидкостью, насос, отличающаяся тем, что она содержит две заслонки, площади которых предварительно рассчитывают для прохода жидкости по двум каналам, внутреннему и наружному, из условия, чтобы теплоотдача наружных и внутренних поверхностей была одинаковой, а зоны нагрева и охлаждения совпадали.1. The method of thermoplastic hardening of parts, which consists in the fact that the parts are heated to temperatures below phase transitions, followed by cooling under a pressure of at least 8 atm, characterized in that the external, internal surfaces, channel and holes of the parts are strengthened simultaneously by the flow of coolant, which is regulated so that the heat transfer from all surfaces of the parts is the same. ! 2. Installation for thermoplastic hardening of parts containing a heating zone, a cooling zone, a container with liquid, a pump, characterized in that it contains two valves, the areas of which are previously calculated for the passage of liquid through two channels, internal and external, so that the heat transfer the outer and inner surfaces was the same, and the heating and cooling zones coincided.
