Description
Technical Field
The utility model relates to an isostatic pressing pressed compact production facility correlation technique field especially relates to an isostatic pressing vibrations anchor clamps for filler.
Background
The isostatic pressing treatment is to place the processed object in a sealed container filled with liquid and to pressurize gradually by means of pressurizing system to apply equal pressure to the surfaces of the object, so as to reduce the intermolecular distance and increase the density without changing the appearance and shape of the object, thereby improving the physical properties of the material.
As a molding process, the isostatic pressing technology has the following characteristics compared with the conventional molding technology:
1. the isostatic molded articles have a high density, typically 5-15 higher than one-way and two-way compression molding. The relative density of the hot isostatic pressing product can reach 99.8-99.09%.
2. The density of the pressed compact is uniform and consistent. In the press molding, the density distribution of the green compact becomes uneven in both of the one-way and two-way pressing. This density variation can often reach more than 10% when pressing complex shaped articles. This is due to the frictional resistance between the powder and the steel die. The isostatic fluid medium transmits pressure, being equal in all directions. The covering and the powder are compressed approximately uniformly, the powder and the covering do not move relatively, the friction resistance between the covering and the powder is little, the pressure is only slightly reduced, the density reduction gradient is generally less than 1%, and therefore, the density of the blank is considered to be uniform.
3. Because of the uniform density, the length-diameter ratio of the manufactured product can be unlimited, which is beneficial to producing rod-shaped and tubular thin and long products.
4. The isostatic pressing process does not need to add lubricant into powder, thus not only reducing pollution to products, but also simplifying manufacturing procedures.
5. The product formed by isostatic pressing has excellent performance, short production period and wide application range. The isostatic compaction process has the disadvantages of low process efficiency and expensive equipment.
Need before the isostatic pressing with alloy powder dress in the die cavity, in order to make the powder can pack into the die cavity closely knit at the in-process of feeding, the conventional method is to rock the die cavity constantly and has reached closely knit effect, though can reach technical effect effectively, but when great or powder weight is great to the die cavity volume, operating personnel hardly rocks for a long time, thereby influence the suppression effect, and what have now rocks the in-process through the motor, do not carry out the centre gripping to the die cavity, therefore, cause the damage to the die cavity, destroy the die cavity even.
