Description
Technical Field
The invention belongs to the technical field of ceramic product production, and particularly relates to a method for automatically connecting a ceramic rolling handle.
Background
The ceramic cup is a cup made of ceramic and used for drinking wine, water, tea and the like. The "ceramic" is a ceramic product formed by making clay into a shape, forming, sintering, etc., drying, and heating to a certain degree to harden it, without dissolving in water. The traditional method is that after the cup is rolled and formed, the water content is reduced until the cup body and the mould can be separated from the mould and then taken out, and then the cup handle is bonded with the cup body. However, the water content of the cup body and the handle is not consistent, so that the phenomena of handle cracking, handle sliding, glaze shrinkage and the like are easy to occur, and the quality is very low.
Disclosure of Invention
The invention aims to provide a method for automatically connecting a handle by ceramic rolling, which aims to solve the problems that ceramic enterprises are difficult to bond handle products, the products are easy to crack, slide, shrink glaze and the like, and the connection between a cup handle and a cup body is more reliable. In order to achieve the purpose, the invention provides the following technical scheme:
a method for automatically connecting a handle by ceramic rolling comprises a die manufacturing step, a pug forming step and a demoulding step; the manufacturing steps of the die specifically comprise: manufacturing two die-opened gypsum dies 1, wherein the two die-opened gypsum dies 1 can be symmetrically divided into two parts, a blank cavity 2 and a handle cavity 3 are arranged in the two die-opened gypsum dies 1, two ends of the handle cavity 3 are communicated with the blank cavity 2, and the top of the blank cavity 2 is open; manufacturing two die sinking gypsum mold jackets 4 matched with the two die sinking gypsum molds 1, wherein the two die sinking gypsum mold jackets 4 are sleeved at the bottoms of the two die sinking gypsum molds 1, so that two parts of the two die sinking gypsum molds 1 are not separated; the two die sinking gypsum mould jackets 4 are matched with the two die sinking gypsum moulds 1 and do not rotate relatively; the mud material forming step specifically comprises: taking pug with the same water content, and dividing the pug into blank pug and handle pug; pre-manufacturing the handle body pug into a handle body 6, and putting the handle body 6 into the handle body cavity 3; matching the two die-opened gypsum dies 1 on the two die-opened gypsum die outer sleeves 4, and putting the blank mud into the blank cavity 2; rolling the blank pug into a blank 5 by a roller press, and rolling the blank 5 and the handle 6 into a whole; the demolding step specifically comprises the following steps: and (3) standing and drying the integrally formed blank body 5 and the handle body 6, taking the two die-opened gypsum dies 1 out of the two die-opened gypsum die jackets 4, opening the two die-opened gypsum dies 1, and taking out the integrally formed blank body 5 and the handle body 6. According to the structure, the blank cavity 2 restrains the outer contour shape of the blank 5, the handle cavity 3 restrains the outer contour shape of the handle 6, and the two ends of the handle cavity 3 are communicated with the blank cavity 2, so that the blank 5 can be automatically connected with the handle 6 in the handle cavity 3 into a whole in the forming process; the top of the blank cavity 2 is open, so that a rolling head of a rolling machine can conveniently extend into the blank cavity 2 to roll and form blank mud; the two die-opened gypsum molds 1 can be symmetrically divided into two parts, so that the two die-opened gypsum molds 1 can be conveniently opened, the handle body 6 is placed in the handle body cavity 3, then the two die-opened gypsum molds 1 are matched on the two die-opened gypsum mold outer sleeves 4, and the two die-opened gypsum molds 1 can be kept closed; the two die sinking gypsum mould jackets 4 and the two die sinking gypsum moulds 1 are matched and do not rotate relatively, so that the roller press can drive the two die sinking gypsum mould jackets 4 and the two die sinking gypsum moulds 1 to rotate integrally, and a rolling head of the roller press extends into the blank cavity 2 to roll and form blank pug. The adopted pug with the same water content is divided into blank pug and handle pug; therefore, the moisture content of the blank body 5 and the handle body 6 is always equal, so that the blank body pug can be well connected with the handle body 6 into a whole in the process of rolling forming, and the defects of handle cracking, handle sliding, glaze shrinkage and the like are avoided. When the blank 5 and the handle 6 are connected into a whole, the moisture content is about 22 percent, and after standing and drying, the blank 5 and the handle 6 which are connected into a whole can be taken out by demoulding. In the traditional method, the blank body 5 and the handle body 6 are both manufactured independently, so that the consistency of the moisture content is difficult to ensure, and the bonding is unreliable.
Furthermore, in the step of forming the pug, when the handle body 6 is placed in the handle body cavity 3, two ends of the handle body 6 exceed the joint of the blank cavity 2 and the handle body cavity 3. According to the structure, the two ends of the handle body 6 exceed the joint of the blank cavity 2 and the handle body cavity 3, so that the blank pug can be combined with the extended handle body pug into a whole in the process of rolling and molding the blank pug.
Further, in the mould manufacturing step, the bottoms of the two mould opening gypsum moulds 1 are opened, and the inner bottoms of the two mould opening gypsum mould outer sleeves 4 are provided with bosses 7; the boss 7 extends into the open bottom of the two opened gypsum molds 1 to form a supporting edge at the bottom of the blank 5. As can be seen from the above structure, the bosses 7 make the bottom of the blank 5 concave, so that the blank 5 does not stick to the platform during the movement.
Further, in the demolding step, the integrally molded blank 5 and the handle 6 are blown by a blower while being kept still and dried. According to the structure, the moisture of the integrally formed blank 5 and the handle 6 is quickly reduced by blowing, and the demoulding time is shortened.
Further, after the demoulding step, the integrally formed blank body 5 and the body 6 are placed in a kiln for sintering. With the above structure, the strength of the integrally formed blank 5 and body 6 can be improved only after they are sintered in a kiln.
Furthermore, the sintering temperature is over 1200 ℃.
Furthermore, in the step of forming the pug, connecting parts are implanted into two ends of the body 6 before the blank pug is rolled into the blank 5 by the roller press; the connecting part comprises a plurality of iron needles welded in the middle; the connecting part scatters from the middle part to the two ends; after the blank body 5 and the handle body 6 are rolled into a whole, the middle part of the connecting part is positioned at the joint of the blank body 5 and the handle body 6. According to the structure, the connecting part comprises a plurality of iron needles welded in the middle, and the connecting part scatters from the middle to two ends, so that the connecting part is embedded in the joint of the blank 5 and the handle 6 after the blank pug is rolled into the blank 5 by the roller press, and two ends of the connecting part are embedded in the blank and the handle 6 like tree roots, so that the connecting strength of the blank and the handle 6 is improved, and the joint is prevented from cracking and dislocation.
Furthermore, the surface of the iron needle is galvanized. According to the structure, the galvanized steel is melted at the temperature of over 1200 ℃, the gap between the blank body and the handle body 6 is filled, and the surface of the iron needle forms a rough surface, so that the connection part, the blank body and the handle body 6 are more reliably connected, the problem of fracture is avoided, and the strength is higher.
