Description

Air-sealing and vacuum dual-purpose PE pipe sizing sleeve die

Technical Field

The utility model relates to a PE manages production field, concretely relates to seal dual-purpose PE pipe sizing cover mould of gas, vacuum.

Background

At present, the PE pipe production comprises the steps of air sealing and sizing and vacuum sizing. The former has large floor area during production, and is not easy to carry out random detection on the PE pipe, so the former is basically replaced by vacuum sizing at present, the vacuum sizing production period is short, the random detection is convenient, and the former is the only feasible production process for producing the PE pipe at present. There are some deficiencies in the main structural design of the vacuum sizing can, which is the main component of the process. For example, the structure is complicated in modeling, the body shape is too large, the occupied area is too much, the material consumption is high in manufacturing, the consumed time and the consumed energy are high, because the cooling vacuum tank is too long, although the observation holes are arranged at the two ends of the tank, the PE pipe cannot be observed and detected (such as the appearance quality of surface smoothness and the like) in production due to too small size, and the defects in the aspect of vacuum sizing exist: first, vacuum sizing is not specific. Secondly, if the vacuum sizing is realized by a vacuum sizing die rather than a vacuum cooling tank because the vacuum sizing is over large in vacuum cavity, if the whole cooling tank is in a pneumatic state, the PE pipe outside the sizing die is pressed and deformed under the condition of poor pneumatic large cooling effect, so that the quality of the PE pipe is unstable. And the air pressure other than the vacuum sizing is wasted. Therefore, the PE pipe sizing sleeve die with small volume and good practical effect needs to be researched.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the above-mentioned problem that exists among the prior art, provide a seal gas, dual-purpose PE pipe sizing cover mould in vacuum, novel structure not only, effectual to the sizing of PE pipe, the cost is lower, can observe the detection to the PE pipe in the production simultaneously.

In order to realize the technical purpose, the technical effect is achieved, the utility model discloses a realize through following technical scheme:

the utility model provides a seal dual-purpose PE pipe sizing cover mould of gas, vacuum, includes outer big envelope, be equipped with hole sizing cover in the outer big envelope, be equipped with between outer big envelope and the hole sizing cover and seal the gas cushion, it is connected through between fastening flange and the outer big envelope to seal the gas cushion, it is equipped with the water shunt to seal between gas cushion and the hole sizing cover, be connected with the inlet tube on the water shunt, it has the drain pipe to pass on the gas outer envelope to seal, the outer big envelope outside is located to the drain pipe other end.

Further, the outer envelope is connected with the PE pipe extruder head through a connecting flange.

Furthermore, a plurality of groups of small holes are formed on the inner hole sizing sleeve.

Further, the outer envelope is made of a metallic material.

Further, the outer end of the water inlet pipe is connected with the water tank.

The utility model has the advantages that:

the utility model is not only novel structure, it is effectual to the sizing of PE pipe, occupation space is little, and the cost is lower, and the PE pipe of producing is of high quality, can observe the detection to the PE pipe in the production simultaneously.
