Integrated ring foot fine blank cup preparation process

Abstract

The invention relates to the field of ceramic preparation processes, in particular to a preparation process of an integrated ring foot sharp blank cup, a blank drawing circular truncated cone is used for drawing and positioning a blank, and due to the fact that the blank drawing circular truncated cone occupies the space in a ring foot, the workload of a ring foot sharp blank in the later period can be reduced; the throwing circular truncated cone made of the gypsum material is beneficial to separation of the throwing circular truncated cone and the green body after being dried, the phenomenon of adhesion of the green body is avoided, and the cone-shaped throwing circular truncated cone is also beneficial to separation of the green body and the throwing circular truncated cone; the throwing circular truncated cone and the blank body can be conveniently separated from the throwing rotary table through the blank lifting opening; vacuum adsorption is carried out on a fine trimming body round table, positioning during fine trimming is facilitated, the centers of fine trimming are consistent, vertical jumping is avoided, and the notch defect caused by jumping is avoided; the opening of the green body is not necked down and is smaller than other parts of the inner cavity of the green body, downward pressure and tensile force are generated on the green body through the expanded air bag, and the green body can be transversely and vertically positioned in cooperation with the positioning ring, so that the precision of the fine trimming is improved, and the notch defect caused by vertical or horizontal jumping is avoided.

Description

technical field [0001] The invention relates to the field of ceramic preparation technology, in particular to the preparation technology of an integrated ring Ashikaga cup. Background technique [0002] The billet refers to the green tire of the utensil (or concentric circle utensil) made by drawing the billet. In its semi-dry state, it is placed on the billet car (pottery drawing machine), and the billet and the car are fixed concentrically. The sharp billet knife is trimmed and polished, so that the shape of the billet is regular and smooth, and the curve is beautiful. In the existing processing technology of the green body and the ring foot, the ring foot is processed by the bonding or turning process, in which the bonding type distributes the forming blank and the ring foot, and then the ring foot and the green body are glued with mud. The knot is integrated and dried and formed. Using this process does not need to sharpen the ring foot, but the disadvantage is that the...

Problems solved by technology

In the existing green body and ring foot processing technology, the ring foot is processed by bonding or turning processing technology, in which the bonding type is distributed to form the green body and ring foot, and then the ring foot and the green body are bonded by mud. The knot is integrated and dried and formed. This process does not need to sharpen the ring foot, but its disadvantage is that the strength of the joint between the ring foot and the green body is not strong enough, and the ring foot is prone to fall; Processing technology, the green body and the ring foot are integrally formed, but in the process of sharpening the billet, because the green body is prone to lateral movement or longitudinal jump, the surface of the green body or the ring foot is prone to notch defects, and the ring foot has more cutting materials , the operation time is long, in view of this, the case arises
