Description
Technical Field
The invention belongs to the technical field of wire mill accessories, and particularly relates to a quick-change multi-lip sealing component matched with a high-speed wire mill.
Background
The quick-change oil-gas sealing ring is a fitting for forming an oil-gas sealing system for the high-speed wire rod rolling mill, namely the structure for forming the oil-gas sealing system comprises a sealing element formed by an elastic sealing ring and a steel supporting ring which are supported by rubber materials and a sealing mechanism formed by an upper sealing sliding ring and a lower sealing sliding ring which are sleeved on two sides of the sealing element and form an upper labyrinth mechanism and a lower labyrinth mechanism, and the sealing mechanism is sleeved in an eccentric disc to form the oil-gas sealing system for the high-speed wire rod rolling mill.
The invention patent with Chinese patent number 201810543917.4 and application publication number CN108506492A discloses a quick-change multi-lip sealing component, the technical proposal of which consists of a sealing mechanism consisting of an elastic sealing ring made of rubber plastic materials and a steel supporting ring which can be sleeved in an eccentric disc, and an upper sealing slip ring and a lower sealing slip ring which are sleeved on the two sides of the sealing mechanism; and the upper part of the ring cylinder forming the upper sealing slip ring is provided with an inner buckling edge. The inner buckling edge structure is beneficial to reducing the possibility that cooling water containing a large amount of impurities enters a sealing structure formed by the upper sealing slip ring and the sealing ring, and the probability that the cooling water enters the opposite lubricating oil roller box through the sealing structure is greatly reduced. However, due to the defect of the internal edge structure, the cooling water can gather at the side, and it is difficult to ensure that the cooling water cannot enter the sealing structure formed by the upper sealing slip ring and the sealing ring.
Disclosure of Invention
The invention aims to provide a quick-change multi-lip sealing component which can basically ensure that cooling water cannot enter a sealing structure formed by an upper sealing ring and a sealing ring.
In order to achieve the purpose, the invention adopts the technical scheme that:
a quick-change multi-lip sealing component structurally comprises:
the eccentric disc comprises a sealing mechanism consisting of elastic sealing rings made of rubber and plastic materials and capable of being sleeved in the eccentric disc, and upper and lower sealing sliding rings sleeved on two sides of the sealing mechanism, wherein an inner buckling edge is arranged at the end part of a ring cylinder forming the upper sealing sliding ring; the method is characterized in that: the outer ring of the inner buckling edge is provided with a ring which can throw cooling water outwards.
The structure of the quick-change multi-lip sealing component further comprises the following additional technical characteristics:
-the thickness of the loop is less than or equal to the thickness of the inside buckle edge;
a plurality of outer throwing groove structures are uniformly arranged on the periphery of the ring;
-said outer throw slots are radially disposed;
-the outer throwing groove is obliquely arranged.
Compared with the prior art, the quick-change multi-lip sealing component provided by the invention has the following advantages: firstly, because the end part of the upper sealing slip ring cylinder is provided with the inner buckling edge, and the outer ring of the upper sealing slip ring cylinder is provided with the ring which can throw cooling water outwards, when the quick-change multi-lip sealing component rotates at high speed, extremely high centrifugal force can be generated on the ring, the cooling water attached to the inner buckling edge is swept out, and the cooling water is effectively prevented from entering the labyrinth mechanism formed by the elastic sealing ring and the upper sealing slip ring; secondly, because a plurality of outer throwing groove structures are uniformly arranged on the periphery of the ring, larger outward-throwing vortex airflow is generated during high-speed rotation of the ring, and the purging effect of the ring on cooling water is further improved.
Drawings
Fig. 1 is a schematic structural view of a quick-change multi-lip sealing member;
FIG. 2 is a schematic structural view of an upper sealing slip ring constituting FIG. 1;
fig. 3 is a schematic side structure diagram of the upper sealing slip ring.
Detailed Description
The structure and the working principle of the quick-change multi-lip sealing component provided by the invention are further described in detail with reference to the accompanying drawings.
Fig. 1, 2 and 3 show schematic structural diagrams of the quick-change multi-lip sealing component and the sealing ring thereon provided by the invention. The structure of the quick-change multi-lip sealing component comprises a sealing mechanism consisting of an elastic sealing ring 2 made of rubber and plastic materials and a steel support ring 3 which can be sleeved in an eccentric disc 1, and an upper sealing sliding ring 4 and a lower sealing sliding ring 5 which are sleeved on two sides of the sealing mechanism, wherein an inner buckling edge 6 is arranged at the end part of a ring cylinder forming the upper sealing ring; the outer ring of the inside edge is provided with a ring 7 having a thickness D1 less than or equal to the thickness D2 of the inside edge and capable of throwing cooling water out.
The working principle is as follows: when the roll shaft A drives the quick-change multi-lip sealing component which is sleeved on the eccentric disc 1 and comprises the upper sealing sliding ring 4 to rotate at a high speed, the ring 7 of the upper sealing sliding ring can form an external blowing air flow in the peripheral area of the ring due to the action of centrifugal force, and negative pressure is formed in a labyrinth mechanism 9 formed by the elastic sealing ring and the upper sealing sliding ring, so that cooling water soaked in the peripheral area can be effectively prevented from entering the labyrinth mechanism 9 formed by the elastic sealing ring and the upper sealing sliding ring from a gap 8 formed between the inner buckling edge and the eccentric disc, and the sealing effect of the quick-change multi-lip sealing component is improved.
In the structure constituting the above-described quick-change multi-lip seal, in order to further enhance the generation of negative pressure in the peripheral region of the ring 7 of the sealing slide ring when it rotates at high speed: a plurality of outer slinger means 10 may also be provided uniformly around the circumference of the hoop, which may be radially disposed but is preferably angularly disposed with a curvature opposite to its direction of rotation F as shown in figure 2.
