Abstract
The invention discloses an ejector header. The ejector header comprises an ejector header body, an ejector rod cap, an ejector rod, and an inner body, wherein the ejector header body is connected with one end of the ejector rod cap; the ejector rod is connected with the other end of the ejector rod cap; the inner body is arranged inside the ejector header body and the ejector rod cap; a seal groove is formed between the inner body and the ejector rod cap; a seal ring is arranged inside the seal groove. According to the invention, cooling water is not allowed to run away from gaps, so that the cooling effect is improved.
Description
Technical field
The present invention relates to a kind of engineering goods, particularly a kind of top.
Background technology
In the production process of steel pipe, need to use top to bore a hole.Top adopts traditional casting technique, this technique to have the features such as workflow is short, production technology is stablized, be easy to grasp, cost is lower always.The condition of work of seamless steel tube production middle punch top is quite severe, and in perforation procedure, top directly contacts with high temperature tube blank inner wall, and pipe reverse rotation, the effect that bear compression, shearing stress, skin-friction force.
Cooling water, in use in order to improve the cooling effect of top, is used in top in inner chamber, but owing to there is gap between top body and push rod cap, gap can make part cooling water run off between gap.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of top, and it can not make cooling water run off between gap, improves cooling effect.
For solveing the technical problem, the invention provides a kind of top, it is characterized in that, it comprises top body, push rod cap, push rod, endosome, top body is connected with push rod Mao one end, and push rod is connected with the other end of push rod cap, and endosome is positioned at top body and push rod cap, between endosome and push rod cap, be provided with a seal groove, in seal groove, be provided with a sealing ring.
Preferably, described top body is shaped as taper.
Preferably, described top body is provided with an inner chamber.
Preferably, in described push rod cap and in push rod, pass a siphunculus, siphunculus is communicated with inner chamber.
Preferably, described top body and push rod Mao junction are provided with obturator.
Preferably, described push rod Mao one end diameter is greater than the other end diameter of push rod cap.
Positive progressive effect of the present invention is: the present invention can not make cooling water run off between gap, improves cooling effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention.
?
The specific embodiment
Lift a preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the present invention that intactly illustrates.
As shown in Figure 1, the present invention top comprises top body 1, push rod cap 2, push rod 3, endosome 6, top body 1 is connected with one end of push rod cap 2, push rod 3 is connected with the other end of push rod cap 2, endosome 6 is positioned at top body 1 and push rod cap 2, between endosome 6 and push rod cap 2, be provided with a seal groove 5, in seal groove 5, be provided with a sealing ring 4, by sealing ring, can effectively prevent that cooling water runs off between gap.
Come directly towards the taper that is shaped as of body 1, can improve like this speed of perforation.
Top body 1 is provided with an inner chamber 7, and the interior use cooling water of inner chamber 7, improves cooling effect like this.
In push rod cap 2 and in push rod 3, pass a siphunculus 8, siphunculus 8 is communicated with inner chamber 7, so conveniently in inner chamber 7, passes into cooling water.
Top body 1 is provided with obturator 9, so further raising sealing property with the junction of push rod cap 2.
One end diameter of push rod cap 2 is greater than the other end diameter of push rod cap 2, convenient for assembly like this.
Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, do not deviating under the prerequisite of principle of the present invention and essence, can make various changes or modifications to these embodiments.Therefore, protection scope of the present invention is limited by appended claims.
