Abstract
The invention relates to a ceramic liquid lifting pipe with a matched movable metal flange, and belongs to the field of low pressure casting tools. An inverted cone-shaped support platform (2) which is integrally processed with a ceramic liquid lifting pipe main body (1) is arranged at the upper port of the ceramic liquid lifting pipe main body (1); the matched movable metal flange consists of a lower half metal flange (3) and an upper half metal flange (4) which are matched with each other; and both the lower half metal flange (3) and the upper half metal flange (4) are provided with a central cone hole (5) matched with the support platform (2), and a central round hole (6) matched with a coaxial extending pipe section (8) above the top surface (7) of the support platform (2). The ceramic liquid lifting pipe can be conveniently and reliably positioned and fixed, and is safe and undamaged when operated normally at a high temperature, so that the service life of the ceramic liquid lifting pipe is prolonged.
Description
Technical field
The invention belongs to low pressure casting apparatus field, relate to a kind of ceramic lift tube with supporting movable metal flange.
Background technology
in prior art, the upper port position of ceramic lift tube main body has the flange that processes with ceramic lift tube main body integral body, in order to being located, ceramic lift tube is fixed on the work top that is in the low press under room temperature environment, during the ceramic lift tube normal operation, the molten aluminum liquid continuous-flow from bottom to top that has high temperature more than 700 ℃ in its pipe, therefore, anxious poly-the expansion occurs near the ceramic material the internal orifice of the flange at upper port position under the effect of high temperature, because the external diameter of the flange of locking face and connecting hole is larger, be under room temperature environment away near the ceramic material the outer rim of the flange of the internal orifice of flange, be difficult to internal orifice near ceramic material synchronize anxious poly-the expansion, therefore, very easily cause the outer rim cracking of flange, the essence of cracking is that near near the ceramic material that outer rim is and internal orifice is expands and can not synchronize, make tension exceed the limit, the result of cracking causes ceramic lift tube to scrap.
Summary of the invention
The technical problem that solves:
By changing the structure that is used for the fixing flange in location of ceramic lift tube, adopt supporting movable metal flange, can overcome the deficiencies in the prior art, can not only facilitate, locate reliably fixedly ceramic lift tube, and safety and nondestructive can guarantee that ceramic lift tube at high temperature works the time, thereby the service life of improving ceramic lift tube.
The technical scheme that adopts:
ceramic lift tube with supporting movable metal flange, comprise the ceramic lift tube main body, in order to the fixing flange of ceramic lift tube, it is characterized in that: the upper port position of ceramic lift tube main body has the brace table of the rounding bench-type that processes with ceramic lift tube main body integral body, flange is the movable metal flange supporting with ceramic lift tube, described supporting movable metal flange is comprised of second metal flange that complements one another and first metal flange, described second metal flange has the center taper hole, the center taper hole is supporting corresponding with the outside conical surface of the brace table of described rounding bench-type, described first metal flange has center hole, it is supporting corresponding that center hole and ceramic lift tube main body are positioned at the face of cylinder, the outside of the coaxial extension pipeline section on the end face of brace table of described rounding bench-type.
Effective effect:
supporting movable metal flange can be convenient, by the brace table of rounding bench-type, ceramic lift tube is located reliably and be fixed on the work top that is in the low press under room temperature environment, structure due to the brace table of rounding bench-type, although the diameter of its end face is greater than the external diameter of ceramic lift tube main body, but less, the diameter of its bottom surface can equate with the external diameter that pottery rises the liquid main body, therefore, near the outer rim of brace table ceramic material---be near near the ceramic material ceramic material with its internal orifice the outside conical surface of brace table of rounding bench-type, in ceramic lift tube more than 700 of continuous-flow ℃ under the molten aluminum liquid effect of high temperature, basically can synchronously expand, can not cause the outer rim cracking because the generation tension goes beyond the limit of, movable metal flange resistance to tension due to supporting is very strong again, be difficult to rhegma, therefore, safety and nondestructive in the time of guaranteeing that ceramic lift tube at high temperature works, greatly improve its service life.
Description of drawings
Fig. 1, main assembly structural representation;
The specific embodiment
Further explanation in detail by reference to the accompanying drawings; In figure, arrow is shown the molten aluminum liquid flow direction.
as shown in Figure 1, the upper port position of ceramic lift tube main body 1 has the brace table 2 of the rounding bench-type that processes with ceramic lift tube main body 1 integral body, flange is the movable metal flange supporting with ceramic lift tube, described supporting movable metal flange is comprised of second metal flange 3 and first metal flange 4 of complementing one another, described second metal flange 3 has center taper hole 5, center taper hole 5 is supporting corresponding with the outside conical surface of the brace table 2 of described rounding bench-type, described first metal flange 4 has center hole 6, it is supporting corresponding that center hole 6 and ceramic lift tube main body 1 are positioned at the face of cylinder, the outside of the coaxial extension pipeline section 8 on the end face 7 of brace table 2 of described rounding bench-type.
As shown in Figure 1, the diameter of the bottom surface of the brace table 2 of described rounding bench-type equates with the external diameter of ceramic lift tube main body 1.
The locking face and the connecting hole that have supporting correspondence on upper and lower semimetal flange 3,4; During application, upper and lower semimetal flange 3,4 sets up from the upper and lower port of ceramic lift tube respectively, then interconnects with the connecting hole of locking member by supporting correspondence, and the location is fixed on the work top of low press simultaneously.
Claims (2)
1. the ceramic lift tube that has supporting movable metal flange, comprise the ceramic lift tube main body, in order to the fixing flange of ceramic lift tube, it is characterized in that: the upper port position of ceramic lift tube main body has the brace table of the rounding bench-type that processes with ceramic lift tube main body integral body, flange is the movable metal flange supporting with ceramic lift tube, described supporting movable metal flange is comprised of second metal flange that complements one another and first metal flange, described second metal flange has the center taper hole, the center taper hole is supporting corresponding with the outside conical surface of the brace table of described rounding bench-type, described first metal flange has center hole, it is supporting corresponding that center hole and ceramic lift tube main body are positioned at the face of cylinder, the outside of the coaxial extension pipeline section on the end face of brace table of described rounding bench-type.
2. the ceramic lift tube with supporting movable metal flange according to claim 1, it is characterized in that: the diameter of the bottom surface of the brace table of described rounding bench-type (2) equates with the external diameter of ceramic lift tube main body (1).
