Embodiment Construction
[0019] The present invention will now be described in further detail with reference to the drawings and embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the constitutions related to the present invention.
[0020] Such as Figure 1-4 As shown, a cone-cut type powder molding granulation device includes: an extrusion tank 1 and a sleeve cone arranged in the extrusion tank 1. The sleeve cone includes an extrusion cone 4 arranged on an outer layer and an inner layer The cutting cone 7, the big end of the sleeve cone is opened downwards, the extrusion cone 4 is arranged with extrusion holes 5, and the extrusion holes 5 are arranged in several horizontal circles on the extrusion cone 4. The cutting cone 7 There are several grid circles on the top, and each grid circle corresponds to a horizontal circle. The extrusion cone 4 can rotate relative to the cutting c...

The invention relates to a conical cut-in type powder forming and granulating device comprising an extruding tank and a sleeved cone arranged in the extruding tank. The sleeved cone comprises an outer extruding cone and an inner cutting cone, the big head of the sleeved cone is open downwards, extruding holes are distributed in the extruding cone, a plurality of horizontal rings of the extruding holes are distributed on the extruding cone, the cutting cone is provided with a plurality of grid rings, each grid ring corresponds to one horizontal ring, and the extruding cone can rotate along the axis of the extruding cone relative to the cutting cone. Internal pressure is generated in the extruding tank through materials extruded in constantly, the materials are extruded out of the extruding holes in a strip shape, and the strip-shaped materials are cut into granules through relative motion generated by a cutting tank and the extruding tank; the grid rings correspond to the horizontal rings in position, the strip-shaped materials entering grid holes can be periodically cut off, and the lengths of the granules are adjustable; a driving device is arranged on the upper portion and cannot influence granulating; because of cap bodies, the materials can be easily extruded to be of the strip structure, and the materials can be actively dug by the cap bodies.
Description
Technical field [0001] The invention relates to a granulating device in the field of powder metallurgy, in particular to a conical cutting type powder molding granulating device. Background technique [0002] Powder metallurgy is the process technology of preparing metal or using metal powder (or a mixture of metal powder and non-metal powder) as raw materials, forming and sintering, manufacturing metal materials, composite materials and various types of products. Powder metallurgy has similarities with the production of ceramics. Therefore, a series of new powder metallurgy technologies can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solving the problems of new materials and plays a pivotal role in the development of new materials. [0003] In the previous process of powder metallurgy, after adding paraffin, rubber, motor oil, plasticizer and other substances, they are fully stirred and mix...
