A preparation device and manufacturing method of a circular wire mesh cold storage filler for a regenerator

Abstract

The invention discloses a manufacturing device and a manufacturing method of heat regenerator circular screen net cold accumulation packing. The manufacturing device consists of a mold handle, an upper support plate, an upper pad block, an upper mold base, a female mold, an upper guide sleeve, an outer demolding plate, a lower guide sleeve, a lower pad, a lower mold base, an upper spring, a feeding plate, a feeding rod, a female mold insert core, an inner demolding block, an outer demolding plate insert core, a male mold core, a lower spring and an isometric sleeve. By adopting the manufacturing device, high-precision size tolerance control on the outer diameter of a screen net is ensured when a circular screen net thin piece is manufactured, the flatness of the screen net thin piece and the blanking quality of the cross section of the outer edge of the screen net are ensured, and meanwhile, the consistence in manufacturing the circular screen net thin pieces in batch is achieved with relatively low cost.

Description

technical field [0001] The technical field of the present invention relates to the field of refrigeration and low temperature engineering and the field of mechanical manufacturing, in particular to a preparation device and a manufacturing method of circular wire mesh cold storage packing for a regenerator. Background technique [0002] Regenerative cryogenic refrigerators are the most widely used varieties of small cryogenic refrigerators, and their representative types include pulse tube refrigerators, Stirling refrigerators, GM refrigerators, Villemeer refrigerators and Solvin refrigerators, etc. . The regenerative cryogenic refrigerator was initially successfully applied in the cooling of military infrared night vision equipment, and then rapidly expanded to other application markets. Wide range of applications. [0003] In the regenerative cryogenic refrigerator, the hot and cold fluids share a flow channel, and the working medium flows alternately in it. They use at ...

Problems solved by technology

The dimensional tolerance control accuracy of the outer diameter of the circular wire mesh sheet by a manual punch or an industrial punching machine is not high, and the flatness of the wire mesh sheet and the section quality of the outer edge are also difficult to meet the requirements, especially in the consistency of batch preparation. , often can only be applied to small-scale research and development in the laboratory, and the low quality of its wire mesh preparation is often one of the key factors affecting the performance of the refrigerator; professional custom-made sets of molds and devices are generally very expensive, only in Refrigerators will only be used when they are put into large-scale production, and when regenerators of different specifications are required, they often need to be re-ordered, resulting in a great waste of resources
