Abstract
The invention relates to a powder material forming pipe fitting forming mold and method. Demoulding of the outer wall of a cylindrical part can be realized by virtue of separation of an outer mould, the demoulding force during demoulding of a core column can be greatly reduced by virtue of dividing the core column into two parts with wedge surfaces, the demoulding of a powder pipe fitting is convenient, and the production efficiency is improved. Simultaneously, one-time forming of non-pattern draft powder dry-pressing pipe fitting of different section shapes can be realized by virtue of changing the section shapes of formed parts of the outer mould and the core column, so that the forming efficiency is high, the formed part is not subjected to mechanical machining damage, and the structural strength is obviously higher than that of secondary machining pieces.
Description
Technical field
Mould and the forming method, particularly big L/D ratio that the present invention relates to a kind of dusty material moulding pipe fitting do not have the dry-pressing formed method of powder and the mould of draft angle pipe fitting.
Background technology
Dry-pressing formed is that the dry powder blank is inserted in the metal die cavity, makes it become the forming method that dense green obtains required profiled member by pressing and heating.Dry-pressing formed because of its production efficiency height, required manually less, percent defective is low, with short production cycle, the extrudate density of production is big, intensity is high, is fit to mass industrialized production, is widely used in the moulding of composite powder, metal dust and ceramic powders.These class powder pressing forming apparatus and method are suggested, for example proposed a kind of powder pressing forming equipment and method, in the Chinese patent of application number 200510005695.3, proposed a kind of powder pressing device and method of suppressing little muffin at Japan Patent No.2000-397967.
The powder compaction equipment that proposes in relevant patent and the document is special equipment, and not only equipment complexity but also equipment are applicable to the product that compact dimensions is less, can cause equipment volume huge during moulding large scale product, and the device fabrication difficulty increases greatly.The ubiquity knockout press is big during powder pressing forming, and this problem highlighted more when the problem of demoulding difficulty, particularly profiled member size were big.Powder dry-pressing pipe for big L/D ratio, in order to be beneficial to the demoulding of mould, pipe fitting needs certain pattern draft, and requires the production of all isometrical powder dry-pressing pipe fitting of inside and outside wall for special use occasion, adopts secondary operations to remove the pattern draft of pipe fitting usually.In the existing powder compacting pertinent literature, only propose the method for powder pressing forming, do not had to propose how to solve the key issue demoulding difficulty in the powder formation of tubes.
Summary of the invention
The technical problem that solves
For fear of the deficiencies in the prior art part, the present invention proposes a kind of mould and forming method of dusty material moulding pipe fitting.
Thought of the present invention is: by employing combined type external mold and wedge shape amalgamation stem stem, and the knockout press when having reduced the pipe fitting demoulding greatly, having solved big L/D ratio does not have draft angle powder dry-pressing pipe fitting is made difficulty greatly because of knockout press problem.And this powder moulding mold simple structure practicality, do not need special powder pressing forming equipment, on general forcing press, can realize the moulding of powder pipe fitting, greatly reduce requirement to former, simplified powder pipe fitting compression moulding technology.
