Description

Pottery inner orifice chamfering device

The invention relates to a chamfering tool used in the process of pottery molding, in particular to a pottery inner orifice chamfering device.

It is well known that pottery products are made of clay with high plasticity and water mixed into pottery mud, and then pre-shaped into a pottery by kneading or molding, and then the pottery must be sintered to solidify into a pottery product.

Due to the ever-changing shapes of pottery products, such as pottery plates, tables, urns or pots, these pottery products often have an inner cavity 11 based on strength, accommodation, or shape requirements, and some of these inner cavities 11 are made of The closed type (as shown in Figure 1a), and some are made into an open type that can communicate with the outside world (as shown in Figure 1b).

In addition, based on the functional requirements of modeling or drainage, water conduction, etc., some bad holes 12 are often opened on the bad body 10 during the pottery molding process of these ceramic products before sintering, and these bad holes 12 are connected. Between the inner cavity 11 and the outside, in other words, the bad holes 12 respectively form an outer orifice 12a on the outer surface 13 of the bad body 10 and an inner surface 14 of the bad body 10 (ie the cavity wall of the inner cavity) An internal orifice 12b is formed, and the body 10 must then be cured and shaped by sintering in order to produce a ceramic article of said shape.

Further, in the prior art of pottery craftsmen, the above-mentioned bad holes 12 can usually be drilled from the outer surface 13 of the bad body toward the inner surface 14 by using some small tools such as rod-shaped or pointed holes, so that the bad body can be drilled. A bad hole 12 which communicates with the inner cavity 11 is formed on the 10 . It is also known that in the process of piercing the bad hole 12, a burr 15 (as shown in FIG. 1c) protruding toward the inner cavity 11 must be formed in the inner hole 12b of the bad hole 12. These burrs 15 are usually sintered and solidified. must be removed before it will affect The forming quality or function of a ceramic product.

However, since the inner holes 12b are all located on the cavity wall of the inner cavity 11 (ie, the inner surface 14 of the bad body 10), the burrs 15 formed by the inner holes 12b cannot be easily removed. In other words, according to the prior art of pottery artisans, only some small hand tools such as scrapers, trowels and the like can only be used skillfully to carefully extend into the bad hole 12 to scrape the burrs 15 around the inner hole 12b, It is inconvenient to operate, and even if the burrs 15 are removed, it is difficult to form a neat chamfer on the equal circumferential end surface of the inner hole 12b, so it needs to be improved.

In view of this, the purpose of the present invention is to provide a pottery inner orifice chamfering device, especially for the bad holes formed by digging on the pottery, to improve the proper rate of removing burrs from the inner orifice, especially to enable the inner hole to be removed.
