Embodiment Construction

[0026] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0027] Such as figure 1 The shown heating device for the medium oil in the working cylinder of the warm isostatic press includes a working cylinder 1, a temperature sensor 2 is installed on the inner wall of the working cylinder 1, and the medium oil in the working cylinder 1 must diffuse Through the temperature sensor 2, a heating unit is arranged beside the working cylinder 1, and the heating unit includes a heating coil 3, an oil outlet pipeline 9, an oil inlet pipeline 10 and a mold temperature controller 11, and the heating coil 3 is installed At the bottom of the working cylinder 1, by setting the heating coil 3 at the bottom, the medium oil at the bottom of the working cylinder 1 can be heated first, so as to reduce the temperature difference between the bottom and the top of the working cylinder 1 and achieve the purpose of temperature compensation. The heati...

Abstract

The invention discloses a heating device for medium oil in a working cylinder of a heating isostatic-pressing machine. The heating device comprises the working cylinder, a temperature sensor is arranged on the inner wall of the working cylinder, a heating unit is arranged beside the working cylinder, the heating unit comprises a heating coil, an oil outlet pipeline, an oil inlet pipeline and a die heater, the heating coil is arranged at the bottom of the working cylinder, the heating coil is communicated with the die heater through the oil outlet pipeline and the oil inlet pipeline, and the temperature sensor is electrically connected with the die heater. The heating device has the beneficial effects that the even temperature of the medium oil in the working cylinder is ensured, and the medium oil is subjected to temperature compensation.

Description

technical field [0001] The invention relates to temperature compensation and uniformity control inside an ultra-high pressure sealed working cylinder of a warm isostatic press, in particular to a heating device for medium oil in a working cylinder of a warm isostatic press. Background technique [0002] The working principle of the warm isostatic press is to put the product to be pressed into the working cylinder, then fill the working cylinder with medium oil of a certain temperature to provide a heat source for the product to be pressed, and then close the working cylinder cover to form a closed space. The medium oil with the same temperature or slightly higher temperature is pressed into the working cylinder through the supercharger for supercharging. Since the flow rate of the medium oil charged into the working cylinder by the supercharger is small, when it enters the working cylinder through a section of pipeline, there will be a certain heat loss and the temperature w...
