Abstract
The utility model provides an outer enhanced type ceramic roller rod. The outer enhanced type ceramic roller rod comprises a roller rod body which is of a circular tube shape and a plurality of protruded reinforcing ribs which are evenly distributed at the outer surface of the roller body. The reinforcing ribs stretch in the axial direction of the body. Due to the fact that the reinforcing ribs which are evenly distributed and additionally arranged at the outer surface of the ceramic roller rod, the sections of the reinforcing ribs are cambered surfaces, when vacuum extrusion molding is carried out, the defects such as micro-cracks cannot be produced due to mechanical stress, concentration of heat stress cannot be caused, the roller rod is not easily damaged in the process of use, and the service life of the roller rod is long. By the adoption of the outer enhanced type ceramic roller rod, yield of products is improved in the process of use, and cost is effectively saved.
Description
Technical field
The utility model relates to a kind of accessory in the Production of Ceramics, is specifically related to a kind of outer reinforced ceramic rod.
Background technology
The roller rod normally is used in the roller kilns of firing ceramic tile, the quench zone blast is big and unstable, the roller rod is easy to distortion, for increasing the intensity of ceramic rod, generally adopt the wall thickness that increases ceramic rod to improve bending resistance now, but the increase of wall thickness has caused the increase of roller rod own wt, if add reinforcement in roller rod appearance, equal to increase wall thickness indirectly and weight increases seldom, the bending resistance of roller rod will strengthen like this.Existing product reinforcement cross section is square or other is than complicated shape, the drawback of this shape is exactly: extrude during production or knockout course easily causes micro-crack, because the roller rod is ceramic material, shape is more complicated, the more easy stress that causes is concentrated, the thermal stress that produces in the high temperature use can be concentrated and act on the micro-crack place crackle is expanded rapidly, thereby causes the fracture of roller rod.Thereby the roller of prior art rod is short service life, has increased production cost so greatly.
The utility model content
The utility model is intended to overcome the deficiencies in the prior art, provides a kind of loading capacity strong, long service life, the outer reinforced ceramic rod that effectively reduces production costs.
The technical solution of the utility model is achieved in that
A kind of outer reinforced ceramic rod, it is characterized in that, the roller rod body and the reinforcement of being located at many projectioies on described this external surface of roller rod that comprise the pipe shape, described reinforcement extends axially along roller rod body, and described reinforcement is evenly arranged adjacent two described reinforcement rounding ofves along the outer surface of roller rod body.
Preferably, the cross section of described reinforcement is semicircular arc.
Preferably, described reinforcement and roller rod body is isometric.
Than prior art, the utility model is by setting up many reinforcements of evenly arranging at the outer surface of ceramic rod, and its beneficial effect is:
1, because the cross section of reinforcement is curved, during vacuum extruding form, can not produce defectives such as micro-crack because of mechanical stress;
2, the globoidal structure of reinforcement can not cause concentrating of thermal stress, and is not fragile during roller rod high temperature uses;
3, in quench zone, roller rod outer surface wind-guiding is smooth and easy, and ceramic tile is operated steadily;
4, the contact area of reinforcement and pottery is little, and roller rod heat radiation itself evenly is difficult for producing distortion, has improved the yields of ceramic tile.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of outer reinforced ceramic rod of the utility model;
Fig. 2 is the cross section structure schematic diagram of outer reinforced ceramic rod shown in Figure 1.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1 and Figure 2, a kind of outer reinforced ceramic rod, the roller rod body 1 and the reinforcement 2 of being located at many projectioies of evenly arranging on roller rod body 1 outer surface that comprise the pipe shape, reinforcement 2 along roller rod body 1 extend axially and roller rod body 1 isometric, the cross section of reinforcement 2 is semicircular arc, and the quantity of reinforcement is different and different with roller rod diameter.In the utility model, the reinforcement 2 of semicircular arc is set on this external surface of roller rod, during vacuum extruding form, can not produce defectives such as micro-crack because of mechanical stress; Simultaneously, the globoidal structure of reinforcement can not cause concentrating of thermal stress, and is not fragile during roller rod high temperature uses; At quench zone, the surperficial wind-guiding of roller rod is smooth and easy, and ceramic tile is operated steadily; The contact area of reinforcement and ceramic tile is little, is beneficial to heat radiation, and the ceramic tile cooling is fast like this, and roller rod itself heat radiation simultaneously evenly is difficult for producing distortion, thereby makes that it is neat to walk brick, has improved the yields of ceramic tile.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (3)
