Abstract
The utility model discloses an ejector head. The ejector head comprises an ejector head body, an ejector rod cap, an ejector rod and an inner body, wherein the ejector head 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 in the ejector head body and the ejector rod cap, a sealing groove is formed between the inner body and the ejector rod cap, and a sealing ring is arranged in the sealing groove. According to the ejector head, cooling water cannot flow away through a gap, and the cooling effect is improved.
Description
Technical field
The utility model relates to a kind of engineering goods, particularly a kind of top.
Background technology
In the production process of steel pipe, need to use a kind of top to bore a hole.Top adopts a traditional casting technique always, and this technique has the features such as workflow is short, production technology is stablized, be easy to grasp, cost is lower.The condition of work of a kind of top of seamless steel tube production middle punch is quite severe, and in perforation procedure, a kind of top directly contacts with high temperature tube blank inner wall, and pipe reverse rotation, the effect that bear compression, shearing stress, skin-friction force.
Top in order to improve an a kind of cooling effect of top, is used cooling water in use in inner chamber, but owing to there is gap between one 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 in the utility model 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 utility model provides a kind of top, it is characterized in that, it comprises a kind of top body, push rod cap, push rod, endosome, a kind of body that comes directly towards is connected with one end of push rod cap, and push rod is connected with the other end of push rod cap, and endosome is positioned at a kind of 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 a kind of taper that is shaped as that comes directly towards body.
Preferably, described a kind of 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 a kind of junction that comes directly towards body and push rod cap is provided with obturator.
Preferably, one end diameter of described push rod cap is greater than the other end diameter of push rod cap.
Positive progressive effect of the present utility model is: the utility model can not make cooling water run off between gap, improves cooling effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
The specific embodiment
Lift a preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
As shown in Figure 1, a kind of top of the utility model comprises a kind of top body 1, push rod cap 2, push rod 3, endosome 6, a kind of body 1 that comes directly towards 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 a kind of 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, can effectively prevent that by sealing ring 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.
A kind of 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.
A kind of body 1 that comes directly towards 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 utility model, but those skilled in the art is to be understood that, these only illustrate, and are not deviating under the prerequisite of principle of the present utility model and essence, can make various changes or modifications to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
Claims (6)
