Abstract
The utility model discloses a kind of jacket for cold isostatic moulding in powder metallurgy, described jacket is the bag shaped structure jacket of one end open, and jacket openend is provided with sealing-plug, is provided with transition backing plate between sealing-plug and material.The material of described jacket is polyvinyl chloride, and wall thickness is 4 ~ 8mm, and base thickness is 10 ~ 25mm; The material of described sealing-plug is rubber stopper; The material of described transition backing plate is foam rubber, and thickness is 30 ~ 50mm.Cold isostatic compaction jacket of the present utility model has that intensity is high, good toughness, oil resistant, withstand voltage, long service life feature, its size and shape can be determined, alternative traditional rubber and latex jacket according to the concrete condition of sheeted product; For the material of not easy-formation, effectively can improve the mouldability of powder, improve raw material availability, and improve the quality of products.
Description
Technical field
The utility model belongs to powder metallurgical technology, is specifically related to a kind of jacket for cold isostatic moulding in powder metallurgy.
Background technology
Cold isostatic compaction is one of important forming method of powder metallurgy, and sheath material selected time shaping and structure have direct impact to the mouldability of pressed compact and product quality.
At present, the cold isostatic compaction of field of powder metallurgy selects the jacket of bi-material mostly: rubber package set and latex jacket.The jacket of this bi-material is all for specific product design, and only for the formed machining of powder stock, difform pressed compact needs to use corresponding jacket to suppress.For easy-formation material, sheath material and structure relatively little on the impact of pressed compact mouldability; But for more difficult shaping material, the edge of pressed compact easily bursts apart, thus affects end product quality, reduce the utilization rate of raw material.For having definite shape, needing to improve further the material (such as molded blank) of density and intensity, these two kinds conventional jackets just cannot employ.
Utility model content
The purpose of this utility model is, for more difficult shaping material, provides a kind of jacket for cold isostatic moulding in powder metallurgy that effectively can improve powder compacting, improve raw material availability.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of jacket for cold isostatic moulding in powder metallurgy, described jacket is the bag shaped structure jacket of one end open, and jacket openend is provided with sealing-plug, is provided with transition backing plate between sealing-plug and material.
Further, the material of described jacket is polyvinyl chloride, and wall thickness is 4 ~ 8mm, and base thickness is 10 ~ 25mm.
Further, the material of described sealing-plug is rubber stopper.
Further, the material of described transition backing plate is foam rubber, and thickness is 30 ~ 50mm.
Cold isostatic compaction jacket of the present utility model, its size and shape can be determined according to the concrete condition of sheeted product.In use, first will treat that laminate material (powder) loads in jacket, and then above material, place transition backing plate, reinstall rubber seal plug, after last forvacuum, use iron wire to tie up sealing.
The beneficial effects of the utility model:
Cold isostatic compaction jacket of the present utility model has that intensity is high, good toughness, oil resistant, withstand voltage, long service life feature, alternative traditional rubber and latex jacket; For the material of not easy-formation, effectively can improve the mouldability of powder, improve raw material availability, and improve the quality of products.
