The dimensional tolerance control accuracy of the inner and outer diameters of the annular wire mesh sheets by manual punches or industrial punching machines is not high, and the flatness of the wire mesh sheets and the quality of the inner and outer edge sections are also difficult to meet the requirements, especially the consistency during batch preparation It is difficult to ensure that it is often only used in small-scale research and development in the laboratory, and the quality of its wire mesh preparation is often one of the key factors affecting the performance of the refrigerator; the general cost of professional custom-made sets of molds and devices is very high , will only be used when the refrigerator is 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

Abstract
The invention discloses a preparation device of an annular screen cold storage packing of a heat regenerator and a manufacturing method thereof. The device consists of a die shank, an upper supporting plate, an upper cushion plate, an upper die holder, an upper clamping plate, a female die, an upper guide sleeve, a guide pillar, an outer stripping plate, a lower guide sleeve, a lower cushion plate, a lower die holder, an upper spring, a knockout plate, a knockout rod, a punching head, a female die core insert, an inner stripping plate, an outer stripping plate insert, a lower spring, a male die core and a contour casing. Through the preparation device and the manufacturing method, the strict requirement on the high-quality annular screen packing during research, development and production of a regenerative refrigerator can be satisfied, not only can the high-accuracy dimension tolerance control on the inner diameter and the outer diameter of an annular screen sheet during production be guaranteed, but also the flatness of the screen sheet and the die-cutting quality of the inner and outer edge sections of the screen can be guaranteed, and the consistency of annular screen sheets during mass production can be realized at a lower 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, and in particular to a preparation device and a manufacturing method of an annular wire mesh cold storage filler for a regenerator. Background technique [0002] As an important branch of cryogenic engineering, small cryogenic refrigerators mainly provide effective cold sources for relevant low-temperature applications, because many scientific instruments must rely on suitable low-temperature conditions to obtain better performance and efficiency, or higher speed and sensitivity etc. According to the different cycle principles and heat exchange methods, small cryogenic refrigerators are often divided into two categories: partition wall type and regenerative type. Regenerative cryogenic refrigerators are the most widely used varieties of small cryogenic refrigerators, and their representative type...
