Abstract

The invention discloses a ceramic ware throwing process, which comprises the following production steps: 1) preparing pottery clay strips from the pottery clay for later use; 2) the ceramic ware forming method comprises the steps of selecting a blank drawing machine body, placing a clay strip on the blank drawing machine body for drawing and forming, wherein the blank drawing machine body comprises a rotary table and a driving machine, drawing and forming a second clay blank by the rotary table under the driving of the driving machine, translating the second clay blank to a position where the rotary table deviates from a central line, fixing the second clay blank on the rotary table for the second time, and drawing a first clay blank formed around the central line of the rotary table on the basis of the second clay blank to obtain the ceramic ware formed by the first clay blank and the second clay blank. The invention has the advantage of reducing the possibility that mud blanks which are not on the same central shaft are combined in a bonding mode, so that the outer surface allowance of the mud blanks is increased.

Description

Ceramic ware throwing process

Technical Field

The invention relates to the technical field of ceramics, in particular to a blank drawing process of a ceramic vessel.

Background

The ware fired with pottery clay is called ceramic, and the ware fired with porcelain clay is called porcelain. Ceramics is a general term for ceramics, stoneware and porcelain. The pottery clay and porcelain clay are used as raw materials, and the ware prepared by the technical processes of proportioning, forming, drying, roasting and the like can be called as ceramic.

In the production process of the ceramic, the pug needs to be shaped firstly, and the pug is made into different shapes on a blank drawing machine.

In the prior art, as shown in fig. 1, a clay material is placed at the center of the upper surface of a rotating disc 15, a driving machine 13 is started, the driving machine 13 drives the rotating disc 15 to move, and a first mud blank 21 and a second mud blank 22 are respectively drawn according to the stretching and retracting of a manipulation, as shown in fig. 1, since the first mud blank 21 and the second mud blank 22 are not on the same central line, a high-temperature-resistant adhesive needs to be respectively coated on the lower surface of the first mud blank 21 and the upper surface of the second mud blank 22, so that the first mud blank 21 is adhered to the upper surface of the second mud blank 22, and for the allowance generated on the outer surface after the first mud blank 21 is adhered to the second mud blank 22, a cutter needs to be used for cutting, so that the production time is prolonged, and the production difficulty is improved.

Disclosure of Invention

The invention aims to solve the technical problem of reducing the process of cutting off the allowance of the outer surface of a blank body so as to shorten the production time, and provides a blank drawing process of a ceramic vessel to solve the problem.

The object of the invention is achieved in the following way:

a ceramic ware throwing process comprises the following steps:

step one, preparing pottery clay strips from pottery clay for later use;

and secondly, selecting a blank drawing machine body, placing the clay strip on the blank drawing machine body for drawing and forming, wherein the blank drawing machine body comprises a rotary table and a driving machine, the rotary table is driven by the driving machine to draw and form a second clay blank from the clay strip fixed on the upper surface of the rotary table, the second clay blank is translated to the position of the rotary table deviated from the central line, the second clay blank is secondarily fixed on the rotary table, a first clay blank formed around the central line of the rotary table is drawn on the basis of the second clay blank, and a blank body consisting of the first clay blank and the second clay blank is manufactured, and the blank body is fired at high temperature to form the ceramic vessel.

Compared with the prior art, the method has the advantages that the second mud blank is moved to be arranged at the position deviated from the central line of the turntable, and then the first mud blank corresponding to the central line of the turntable is drawn and formed, so that the possibility that mud blanks which are not on the same central axis are combined in a bonding mode, and the allowance of the outer surface of the mud blank is increased is reduced.

Detailed Description

A ceramic ware throwing process comprises the following steps:

step one, preparing pottery clay strips from pottery clay for later use;

and step two, selecting a blank drawing machine body 1, placing the clay strips on the blank drawing machine body 1 for drawing and forming, wherein the blank drawing machine body 1 comprises a case 11, three lifting columns 12 which are distributed triangularly are fixedly connected below the case 11, a mud blocking basin 14 is fixedly connected to the upper surface of the case 11 relative to the triangular center line positions of the three lifting columns 12, a rotary table 15 is rotatably connected to the center position of the mud blocking basin 14, and a central rotating shaft of the rotary table 15 penetrates through the case 11 and is rotatably connected with a driving machine 13 arranged below the case 11, as shown in fig. 2.

Referring to fig. 2 and 3, if the clay rod is placed at the center of the upper surface of the turntable 15, the driving machine 13 is started, so that the driving machine 13 drives the turntable 15 to move, and the second clay blank 22 formed around the center line of the turntable 15 is drawn according to the stretching and retracting of the manipulation.

As shown in fig. 4, the bottom of the second blank 22 is peeled off the upper surface of the turntable 15, and is translated to a position deviated from the center line of the turntable 15, and as shown in fig. 5 and 6, a first blank 21 is drawn and molded above the second blank 22 corresponding to the center line of the turntable 15, i.e. the ceramic vessel 2 composed of the first blank 21 and the second blank 22 is manufactured.

The ceramic vessel 2 drawn by the embodiment is integrally formed with the first mud blank 21 through the second mud blank 22, so that the process of cutting off the allowance of the outer surface of the blank body is reduced, and the time for producing the ceramic vessel 2 is shortened.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the overall concept of the present invention, and these should also be considered as the protection scope of the present invention.
