Problems solved by technology

[0004] The bottle heads formed by the above method are all wet blanks, that is, the moisture content of the ceramic raw materials is still high after being formed into bottle head blanks, and the final shape and structure need to be completed by drying after molding, and the subsequent drying process is easy. It causes the deformation of the shape of the bottle head itself, and for ceramic wine bottles whose small structural changes will affect the sealing effect, the qualified rate of the product is greatly reduced
At present, the most suitable method has not been found in the method of preparing ceramic bottle heads with a method of small deformation in the prior art.

Embodiment 1

[0029] The preforms were prepared according to the different methods described below, and the results of the final products resulting from the different methods of making the caps were compared.

[0030] Method 1: Stamping combined with cutting forming: use a steel mold that is convenient for rapid stamping forming to stamp the dry blank of the bottle head (such as figure 1 ). Steel die stamping has certain requirements for forming raw materials. The raw material in the present invention is after the ceramic slurry is spray-dried and granulated, and then punched and formed by a steel mold. The parameters of stamping combined with cutting forming are: first, the bottle head blank is processed into blank slurry, which contains 1 to 6% dextrin, and the fineness of the blank slurry is less than 250 mesh, and the concentration is 40 to 55 ° Be (Baume degree ); after spray drying and granulation, the air inlet temperature of the spray drying granulation tower is 220-360°C, and the...

Embodiment 2

[0043] Prepare ceramic wine bottles according to method 1 of Example 1, compare the influence of the water content of the body blank on the subsequent glazing and firing results during assembly and molding, and screen out the optimum water content of the bottle body.

[0044] When the bottle head dry blank and the bottle blank are assembled and formed, the moisture content of the bottle blank is controlled to be less than 8%, 10-13%, 20-23%, and 25-27%, respectively, and the subsequent dipping effect and final firing are compared. As a result, see Table 2 for the results.

[0045] Table 2 Comparison results of preforms with different moisture content

[0046]

[0047] Summary: According to the above table, it can be seen that when the bottle body is finally assembled and formed, the moisture content in it is controlled between 10-23%. Use the shrinkage process of the subsequent drying bottle body to make the connection more firm and the bottle mouth more precise. If the b...

Embodiment 3

[0049] According to the method 1 of embodiment 1, forming the bottle head and directly punching the bottle head respectively, comparing the production efficiency and the final product result of the two methods. For the bottle head blank that is directly stamped and formed, first make a Huff steel mold according to the shape of the bottle head, and the bottle head blank and the assembly and forming method are the same as method 1 in embodiment 1. Compare the average time required to produce one preform by the two methods, and examine the results after firing. See Table 3 for the results.

[0050] Table 3 Comparison results of two bottle head forming methods

[0051]

[0052] Summary: According to the above table, it can be seen that compared with the direct stamping forming method, the production efficiency of the stamping combined with cutting forming method is increased by more than 80%, and the precision of the bottle mouth is higher.

Abstract

The invention discloses a method for producing a bottle head through stamping and cutting combined molding, which is used for firing ceramic wine bottles and includes the following steps: performing spray drying pelleting on ceramic bottle head blank pulp, simultaneously designing to manufacture a mold according to the shape of the bottle head, and performing stamping molding for bottle head blank particles obtained through spray drying through the mold to obtain a bottle head dry blank; performing cutting processing on the bottle head dry blank, and accurately cutting off redundant parts not according with the shape of the bottle head through the fast stamping molded mold; molding a bottle body in slip casting method or other methods and then processing a bottle body blank; and bonding the bottle head dry blank and a bottle body dry blank or a bottle body wet blank through bonding pulp. The method is used for producing the ceramic wine bottle head based on the selected most suitable stamping and cutting combined molding method. Size accuracy of the produced bottle head is high and completely accords with accuracy of a mechanically processed bottle cover. Simultaneously, the method for producing the bottle head through stamping and cutting combined molding can achieve mechanized and automated production and greatly improves labor productivity and product percent of pass.

Description

technical field [0001] The invention relates to a method for preparing a ceramic wine bottle, in particular to a method for preparing a bottle head by combining punching and cutting. Background technique [0002] Ceramic wine bottles are being used more and more widely as packaging containers. The advantages of ceramic wine bottles are obvious, especially for liquor packaging, which is conducive to the aging of wine and makes the wine more mellow and soft. Generally, ceramic wine bottles are mainly made of silicate mineral raw materials through processing, molding, drying, glazing and firing. [0003] As a packaging container, ceramic wine bottles have high requirements for the accuracy of the size of the bottle head. In the process of making ceramic wine bottles in the prior art, in order to reduce the deformation of the bottle head, split molding is usually used, and then the overall assembly is carried out. The body is formed by hollow grouting molding or other methods...
