Internal high-pressure forming pushing head device
Technical Field
The utility model relates to an interior high pressure shaping device of pushing away.
Background
The internal high pressure forming technology is also called hydraulic forming or hydraulic forming, and is a method for forming hollow parts by using liquid as a forming medium and controlling internal pressure and axial pressure. The internal high pressure forming technology can be divided into the following steps according to the shape of a processed blank: hydraulic forming of plates, hydraulic forming of shells and hydraulic forming of pipes. Aiming at hydraulic forming of a pipe, the basic principle is that the tubular material in a mould is controllably deformed by high pressure of liquid and axial thrust of a push head, so that the tubular material with the required shape is obtained. At present, interior high pressure forming technology develops rapidly, but some realistic problems need to be solved urgently, for example, the sealed problem of pushing head and pipe fitting, if sealed not well, can produce the leakage, the pressure that the leakage leads to high pressure forming liquid then is uncontrollable, finally leads to the not enough defect of pipe fitting shaping.
For example, chinese patent CN106378376B discloses an internal high pressure forming multi-stage sealing device, which comprises a pushing head, a sealing rubber ring i, a sealing rubber ring ii, a side cylinder and a telescopic cylinder. Two sealing rubber rings are arranged between the pushing head and the side cylinder and are used as first-stage sealing; the front end face of the push head is set to be an inclined push face, second-stage sealing among the push head, the pipe fitting and the die can be formed, the sealing effect is good, leakage of high-pressure liquid on the push head can be greatly reduced, and leakage of the joint of the push head and the pipe fitting is effectively reduced. In actual production, however, the leakage problem is mainly concentrated between the pipe fitting and the push head, and the leakage of the push head per se can be ignored.
Disclosure of Invention
For overcoming above not enough, the utility model provides an interior high-pressure forming cuts somebody's hair device realizes that high-pressure forming is high-efficient sealed in the tubular material.
The utility model discloses the technical scheme who takes:
the utility model provides an interior high pressure shaping device of cutting somebody's hair, including the direction cone, the sealed cowling, sealing washer I, sealing washer II, sealing washer III, go up the mould, by the shaping pipe fitting, sealed cone, the telescoping cylinder, the high pressure oil circuit, connector II, connector I, connecting screw, the bed die, the direction cone is located by inside the shaping pipe fitting, after the sealed cowling is located the direction cone, through connecting screw and the cooperation of connector I, sealed cone passes through connector I and is connected with the direction cone, the telescoping cylinder passes through connector II and is connected with sealed cone.
Furthermore, the contact position of the end part of the sealing cover and the formed pipe fitting is a ball head, the size of the radial section of the formed pipe fitting of the sealing cover is 1mm larger than the diameter of the formed pipe fitting, and three sealing rings, namely a sealing ring I, a sealing ring II and a sealing ring III, are arranged at the matching position of the sealing cover and the connector I.
Furthermore, the diameter of the bottom surface of the sealing cone is larger than that of the pipe to be formed, a spigot is arranged on the contact conical surface of the sealing cone and the pipe to be formed, and the spigot is arranged at the contact position of the pipe to be formed and the sealing cone.
Furthermore, high-pressure oil ways are arranged inside the telescopic cylinder, the connector II, the sealing cone, the connector I and the guiding cone.
The utility model provides a pair of interior high pressure shaping device of cutting somebody's hair, the direction cone realizes cutting somebody's hair and gets into the direction function when being become the shaping pipe fitting, sealing washer I, sealing washer II, the sealed effect of sealing boot and connector I is realized to sealing washer III, the sealing boot bulb with by the first sealed face effect of shaping pipe fitting inner wall contact performance, exert pressure to the sealing boot by the inside high-pressure liquid of shaping pipe fitting, the sealing boot expansion, the sealing boot bulb with by shaping pipe fitting inner wall contact inseparabler, form and strengthen first sealed face. The sealing cone is provided with a spigot on the conical surface, when the telescopic cylinder provides axial thrust, the axial thrust is transmitted to the formed pipe fitting through the spigot, and the formed pipe fitting is tightly attached to the spigot to form a second sealing surface. The first sealing surface, the reinforced first sealing surface and the second sealing surface act together, so that the sealing effect between the formed pipe fitting and the push head is optimal.
