Mechanical pressure apparatus of sintering furnace

Abstract

The invention relates to a mechanical pressure device applied to a common or low-pressure atmosphere sintering furnace, which comprises a pressing head, a support and guide mechanism, a mechanical pressure mechanism, a mechanical power-transmission mechanism, and a pressure detection mechanism. The mechanical pressure mechanism comprises a screw and an energizing pan which is arranged at the upper end of the screw, the mechanical power-transmission mechanism comprises an upper slip pan, a lower slip pan, and a power-transmission spring, the pressure detection mechanism comprises a scale and apointer. The assembly way is that the mechanical pressure mechanism and the mechanical power-transmission mechanism are arranged on the support and guide mechanism; the scale is arranged on the support and guide mechanism, the pointer is arranged on the mechanical power-transmission mechanism; the pressing head is inserted and arranged in the guide hole arranged at the support and guide mechanism, when the pressing head works, the upper end of the pressing head contacts with the mechanical power-transmission mechanism, the lower end of the pressing head contacts with the sintered sample in the sintering furnace. The mechanical pressure device not only has the advantages that the structure is simple, and the cost is low; but a plurality of mechanical pressure devices can be arranged on onesintering furnace, thereby pressuring a plurality of sintered samples or applying non-equilibrium pressure on one sintered sample.

Description

technical field [0001] The invention belongs to a pressure device (also known as a pressure device) for a sintering furnace, in particular to a mechanical pressure device for an ordinary sintering furnace and a general atmosphere sintering furnace. Background technique [0002] When materials or finished products are prepared by sintering under pressure, the density of materials and samples can be increased, various voids can be reduced, especially for the formation of excellent heterogeneous interface structures, and the function of sample devices can be improved. important role. Among them, the pressure device or pressurization device matched with the sintering furnace is an indispensable equipment. Existing pressure devices or pressurizing devices are generally hydraulic structures, and the pressure head is controlled by the hydraulic system and provides pressure (for example: the pressure device in the "hot-pressed sintering furnace with gas protection" with the announc...

Problems solved by technology

Existing pressure devices or pressurizing devices are generally hydraulic structures, and the pressure head is controlled by the hydraulic system and provides pressure (for example: the pressure device in the "hot-pressed sintering furnace with gas protection" with the announcement number CN2386409, the approval number is The pressure device in the "vertical pressurized continuous sintering furnace" of CN1019173, and the pressurization device in the "vacuum-hot-pressed sintering furnace" of CN1825041), and the hydraulic pressure device is not only relatively complicated in structure, but also has high cost and is not easy Maintenance requires power consumption, and it is not convenient to set up multiple sets on one sintering furnace, and it is difficult to implement unbalanced pressure on the sintered sample
