The nichrome orifice ring comprises a bowl wall, wherein a discharging hole is arranged in the bowl wall, a transition round angle is arranged on a connecting place between the bowl wall and the discharging hole, the arc top point of the transition round angle faces towards the outer side of the bowl wall, the radius of the transition round angle can be 6-30mm, an alloy ring is arranged on the upper end of the discharging hole, the bowl wall is made of a quartz material, and the alloy ring is made of a nichrome material. The nichrome orifice ring has the advantages of reasonable structure, simple connection and long service life.
Description
Technical field:
The utility model relates to a kind of feeding machine part, is specifically related to a kind of pyrolic alloy orifice ring.
Background technology:
In the glasswork production technique; The gob shape determines to lock the glass workpiece quality of compacting to a great extent; And orifice ring is one of two big key equipments that obtain desirable gob shape; In the gob production process, let weight and the shape of gob in orifice ring, push as far as possible and form by the drift of artificial control, get rid of the influence of effects such as gravity.Also have, feeding machine prevents that gob from leaking a very important technology of discharge hole downwards because of conducting oneself with dignity, exactly in accent makes progress process; Form negative pressure in accent and material between the hole, and in present conventional art is produced, the cut a piece of glass mould of rod of tradition all adopts common quartzy orifice ring; Though the quality of quartzy integral body improved a lot in recent years; Never too big technical breakthrough, the cycle that general mould uses is only about 20 days, and mould is after using the later stage; Have a large amount of crackles, the thickness of external diameter can be inhomogeneous when serious.
The utility model content:
The utility model technical problem to be solved be to overcome existing technological deficiency provide a kind of rational in infrastructure, connect simple, duration of service of persistent a kind of pyrolic alloy orifice ring.
Technical scheme below the utility model technical problem to be solved adopts realizes:
A kind of pyrolic alloy orifice ring is characterized in that: comprise a bowl wall, be provided with discharge hole in the said bowl wall, the junction between said bowl wall and the material hole is provided with knuckle, and the circular arc summit of said knuckle is towards the outside of bowl wall.
The radius of said knuckle can be 6～30mm.
Said bowl wall is that quartz material is processed.
Said discharge port upper end is provided with an alloy hoop, and said alloy hoop is the pyrolic alloy material.
The beneficial effect of the utility model is: the pyrolic alloy ring is corrosion-resistant, and hardness is high, can effectively use for a long time.The utility model is rational in infrastructure, connection is simple, duration of service is lasting.
Description of drawings:
Fig. 1 is the vertical view of the utility model.
Fig. 2 is the sectional view of the utility model.
Embodiment:
For technique means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Like Fig. 1 and shown in Figure 2, a kind of pyrolic alloy orifice ring comprises bowl wall 1; Be provided with discharge port 2 in the bowl wall 1; Junction between bowl wall 1 and the discharge port 2 is provided with knuckle 3, and the circular arc summit of knuckle 3 is towards the outside of bowl wall 1, and the radius of knuckle 3 can be 6～30mm; Discharge port 2 upper ends are provided with an alloy hoop 4, and alloy hoop 4 is the pyrolic alloy material.
More than show and described ultimate principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification sheets that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
