Description

dry pulling method

The present invention relates to a dry pulling method, in particular, it utilizes the step of earthing, cutting, opening, centering, pressing, plasticizing and embossing in sequence, so that the Under the condition of additional water, the breaking effect is realized, and it is used for high-temperature kiln firing to make ceramic parts. Since no water is added, the water content of the clay block can be kept in the best operating range, and the texture is firmer and more supportive. , Good structural strength, very suitable for direct shaping processing.

Traditionally, in the process of hand-pulling raw pottery clay (or wet soil), it is necessary to continuously add water to keep the water content above 45%, so as to ensure that the pottery clay is properly lubricated, and it is convenient to shape it by hand kneading. So it will cause trouble in operation.

Furthermore, when the original clay is continuously added with water during the process of hand-drawing, the clay will continue to be lost. Generally speaking, the manufacturer will not recycle the lost clay. Because of the lack of economic benefits, the loss of clay is very large. Not only does the cost increase, but it also causes sedimentation after the clay is discharged to block the waterway, and even causes the operator and the environment to become muddy and dirty everywhere.

As for the quality of stretching, due to the continuous addition of water in the hand-stretching, the water content of the clay becomes high, and the texture is soft and rotten, so the support and structural strength are extremely poor, which will be limited in the creation of shapes and cannot be used to express oneself. The system fails, and the technical difficulty is quite high, and those who are not skilled in technology cannot complete the broken program. If you want to make a thin-walled finished product, it will inevitably fail to form, or the thickness of the finished product needs to be greatly increased, which cannot achieve the desired creative purpose, such as visual beauty or light and handy feel.

In addition, the traditional wet pulling method cannot immediately emboss and emboss on the surface of the finished product, because the water content is high, the texture is soft and rotten, and the support and structural strength are extremely poor. Therefore, in practice, it is necessary to wait for the finished product to dry Only with proper mechanical strength can engraving or grinding be used to process various patterns on the surface, which will greatly lengthen the processing time, which is not conducive to the competitiveness of the product.

Therefore, there is a great need for an innovative dry pulling method, which uses a blanking tool to complete the blanking step, and then when the turntable rotates the cylindrical cup, the side wall of the cylindrical cup is vertically stretched to a preset height, and is Use the plastic edge tool to bend the appearance shape of the edge crimping to the preset appearance shape, especially, use the embossing tool to press the preset circular embossing pattern on the edge of the plastic edge, so for beginners or unskilled hands Those who are clumsy can easily get started and produce the desired finished product, and the overall operation difficulty and failure rate are relatively low, so as to solve the above-mentioned problems of the prior art.

The main purpose of the present invention is to provide a dry pulling method, which includes the step of digging the soil, the step of cutting into pieces, the step of opening the hole, the step of centering, the step of pressing the edge, the step of molding the edge and the step of embossing, which is used in different Under the condition of adding additional water, it can achieve the effect of breaking, and it can be fired in a high-temperature kiln to make ceramic parts.

First of all, the clay step is the process of beating, beating, throwing or kneading the original pottery clay after screening and filtering, adding water to form a uniform wet pottery clay, wherein the wet pottery clay has a water content of 12-18%. The water content of the wet pottery clay refers to the weight percentage of the weight of water in the wet pottery clay to the weight of the wet pottery clay.

In the step of dicing, wet pottery clay is diced and separated, and the bottom part, wherein the clay block is a rectangular block with a thickness and a rectangular appearance, and the bottom part is a round shape with a thickness and a circular appearance Lumps.

In the hole-opening step, the mud mass is curled to form a hollow cylinder, and the bottom part is joined to one end of the hollow cylinder to close to form a cylindrical cup with an opening, a central cavity and a bottom, wherein the bottom part And the joint between the hollow cylindrical parts can be directly touched with water to achieve.

In the centering step, the cylindrical cup is placed on the turntable, and the bottom of the cylindrical cup is stuck on the turntable, wherein the turntable is rotated along the direction of rotation by manual or mechanical force, and thereby drives the circle At the same time, adjust the position of the cylindrical cup to ensure that the cylindrical cup is at the rotation center of the turntable, so as to maintain stable rotation and avoid shaking or swinging.

In the crimping step, the cylinder is stretched vertically using at least one crimping tool directly through the opening to contact the inside of the side wall of the cylindrical cup while the turntable is turning the cylindrical cup and without adding water The height of the cup reaches a predetermined height to form a blanking, or it is formed by using at least one blanking tool to contact the inner side and the outer side of the side wall at the same time to clamp and squeeze to stretch the height of the cylindrical cup Blankholder broken with preset height.

In the edge molding step, when the turntable rotates the blank holder, and without adding water, directly use at least one plastic edge tool to contact at least one of the inner side and the outer side of the blank holder to bend the appearance shape of the blank holder To the preset appearance shape to form plastic edge damage.

In the embossing step, when the turntable is rotating the plastic edge, and without adding water, at least one embossing tool is directly used to contact the outer surface of the plastic edge to form a finished product with a preset circular embossing pattern, It is used for high-temperature kiln firing to make ceramic parts.

Further, the above-mentioned crimping tool includes a crimping handle and a crimping end, wherein the crimping end is connected to one end of the crimping handle and rotates around the crimping handle, and the crimping end has a A smooth surface with a spherical or ellipsoidal or cylindrical appearance.

In addition, the edging tool includes a edging handle and a edging end, and the edging end is connected to one end of the edging handle and rotates around the edging handle, wherein the edging end has a smooth surface, And contains spherical appearance or ellipsoidal appearance.

Furthermore, the embossing tool includes an embossing handle and an embossing end, wherein the embossing end is one end connected to the embossing handle, and rotates around the embossing handle, especially, the embossing end has a concave-convex shape patterned surface.

Therefore, the present invention directly uses the blanking tool to complete the blanking step without additional water addition, and then when the turntable rotates the cylindrical cup, the side wall of the cylindrical cup is vertically stretched to a preset height , and use the plastic edge tool to bend the appearance shape of the edge crimping to the preset appearance shape, especially, use the embossing tool to press out the preset circular embossing pattern on the surface of the edge crimping, so it is not suitable for beginners or technical Skilled hand-clumsy people can easily get started and produce the desired finished product, and the overall operation difficulty and failure rate are relatively low.
