Molding device of thickening powder material

Abstract

The invention provides a molding device of a thickening powder material, and relates to the technical field of powder depolymerization (homogenization) preparation and molding of blank bodies. According to the device, an action principle of polarized electrification of a high-voltage discharging needle or electrification by friction caused by air stream impact is utilized, the powder shows the same electric charge, rejection reaction is increased so as to control aggregation of the powder, and a conventional powder depolymerization (homogenization) preparation process is replaced, so that thequality and the efficiency of the depolymerization operation can be improved, the corresponding equipment input and workload are reduced, and the working cost is reduced. Meanwhile, in a static fieldof a blank body molding process, an alternating current electromagnetic field sensing device is additionally arranged, so that gas (air and negative ion gas) filled between powder materials is once ionized, directional vortex motion is carried out under an effect of an induced electric field, the phenomena that ions are escaped from a powder coating and then electric charge carried in the powder is neutralized are effectively terminated, the self-limitation property is eliminated, and the thickness dimension of the powder coating can be effectively increased and controlled; meanwhile, production procedures can be simplified, so that the production efficiency is improved, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of powder molding, in particular to a thickening powder material molding device. Background technique [0002] The traditional production process of powder materials is: batching → blank preparation → blank forming and drying → sintering or curing. However, powder agglomeration inevitably occurs during the billet preparation process. Since the powder has a tendency to agglomerate spontaneously, and the existence of agglomeration will greatly affect the advantages of the material and the final performance of the product, so how to improve the dispersion and stability of the powder is a very important operation process. [0003] In the billet preparation process, the common powder depolymerization (homogenization) methods are: [0004] (1) Mechanical dispersion, the agglomerated powder is forced to be separated by mechanical force, and the mechanical force must be greater than the bonding force between parti...
