Abstract
The utility model discloses an end surface sealer comprising a shell body, wherein the bottom end part of the shell body is connected with an outlet on the end surface of a vacuum box to form a vacuum cavity; the inner wall at the middle part of the shell body is provided with an annular boss; and an annular elastic sealing body is arranged on the annular boss. The sealer is characterized in that: an adjusting screw rod is arranged on the annular elastic sealing body in an extruding manner and is screwed with a thread on the inner wall of the shell body in a threaded manner; and the annular elastic sealing body is in gapless contact with the surface of a pipe. As the adjusting screw rod is in direct contact with the annular elastic sealing body and a gasket is not needed between the adjusting screw rod and the annular elastic sealing body, the structure is simpler, the manufacturing is easy and the sealing property between the pipe and the sealing body is good; in addition, the sealing body has long service life and is simple to replace.
Description
Technical field
The utility model relates to a kind of vacuum box of pipe production line counterpart, is specifically related to a kind of end face sealer for vacuum box of pipe production line that is used for.
Background technique
The effect of vacuum box of pipe production line is to provide vacuum to a certain degree, is unlikely to subside in the cooling shaping process to guarantee tubing, and its difficult point is that the end face outlet of vacuum box should allow tubing smoothly by keeping enough sealabilities again.Pipe production line all is continuous production, it goes out pipe speed at 2-10m/min, existing way is with the thick silica gel plate of 10 ㎜, by hand cut and the much the same hole of tube outer diameter, couple together with bolt and vacuum box, main elasticity and tube surfaces by silica gel self keeps sealing, owing to carrying out sliding friction between tube surfaces and the sealing material always, cut the hole low precision in addition, the silica gel wear-resisting property is limited, therefore have only 2-3 days the working life of each silica gel sealing plate, best also with regard to about a week.This shows if only rely on the elasticity and the tube surfaces sealing of seal self, just be difficult to improve working life, it is frequent equally also can to cause accessory to be changed, and influence manufacturing efficiency, the while also very uneconomical (market price of silica gel plate should about 40-50 Yuan/㎏).Indivedual producers are also arranged, replace silica gel plate with the molded rubber seal ring, but effect neither be very desirable.
The model utility content
In view of above-mentioned deficiency, it is a kind of simple in structure that the purpose of this utility model is to provide, good seal performance between tubing and the seal, and seal long service life, replacing simply are used for the sealer of vacuum box of pipe production line end face.
In order to achieve the above object, the utility model has adopted following technological scheme: a kind of sealer, comprise housing, described housing bottom connects the vacuum box end face outlet and forms a vacuum chamber, described housing middle part inwall is provided with an annular boss, and the cyclic spring seal is placed on the annular boss, is extruded with adjusting screw rod on the described cyclic spring seal, its adjusting screw rod axially has the through hole of freely coming in and going out for tubing, and the screw thread on adjusting screw rod and the inner walls is screw thread and screws; Described cyclic spring seal is no gap with tube surfaces and contacts.
Optimum, described cyclic spring seal is a hollow ring elastic caoutchouc seal.
Working principle of the present utility model is: tubing comes out to enter sealer from the vacuum box of pipe production line end face outlet, exert pressure to the equilibrium of cyclic spring seal by adjusting screw rod, deformation very easily takes place in cyclic spring seal under external force, so just there is enough pressure to keep sealing between cyclic spring seal and the tube surfaces.Along with the carrying out that produces, cyclic spring seal and tube surfaces do not have the contact position, gap and can wear and tear because of friction, but, the pressure outside that has the adjusting screw rod equilibrium that the cyclic spring seal is applied keeps the trend of distortion owing to making it always, do not contact the wear limit that (sealing) state can remain to the cyclic spring seal always so the cyclic spring seal has the gap with tube surfaces, its working life naturally can be more much longer than the cyclic spring seal of free state.It is also quite convenient to change the cyclic spring seal that may wear to the limit simultaneously, can not finish in one minute by any instrument, increases work efficiency greatly.
The utility model is directly contacted with the cyclic spring seal by adjusting screw rod, need not to place pad between the two, makes structure more simple, easy to manufacture, good seal performance between tubing and the seal, and seal long service life, replacing are simply.
