The specific embodiment
For making above-mentioned purpose of the present utility model, feature and beneficial effect can become apparent more, below in conjunction with the drawings and specific embodiments among the utility model embodiment, the technical scheme among the utility model embodiment are clearly and completely described.
Steel-plastic composite pressure pipe port enlarging device as shown in Figure 1 and Figure 2, its key improvements is: comprise framework, be fixed in the framework lifting body and with the supporting squash type enlarging mechanism in lifting body top.
Jack base 1 that described framework comprises ring shaft base 5, be arranged in parallel with ring shaft base 5 and two ends are hinged on the pull bar 14 on ring shaft base 5 and the jack base respectively; The axis of ring shaft base 5 and jack base 1 coincides, and around the axis of ring shaft base 5 and jack base 1 pull bar 14 is set evenly, and the hinged-support that pull bar 14 two ends are arranged on respectively and evenly on ring shaft base 5 and the jack base 1 is hinged.
Described lifting body is a jack 3, and described jack base 1 is provided with semi-cylindrical shaped jack holddown groove with the inboard.
Described squash type enlarging mechanism comprises gripper shoe 13, Internal baffle 6, compression spring 16, outer baffle 11, push rod 4, axle 7 and block rubber 8, described gripper shoe 13 and Internal baffle 6 are located at the left and right sides of ring shaft base 5 respectively, gripper shoe 13 is fixedly mounted on the push rod of jack 3, be provided with push rod 4 between gripper shoe 13 and the Internal baffle 6, push rod 4 is evenly arranged around gripper shoe 13 axis, described push rod 4 passes the through hole that is provided with on the ring shaft base 5, axle 7 is fixed on the left side of ring shaft base 5 by being threaded, the axis of axle 7 and the dead in line of ring shaft base 5, axle 7 passes the hole that is provided with on the Internal baffle 6, and sets gradually block rubber 8 in Internal baffle 6 left sides, outer baffle 11 and the locking nut 12 that is threaded with axle head.Between Internal baffle 6 and outer baffle 11, block rubber is set, in the time of jack 3 jackings between Internal baffle 6 and the outer baffle 11 relative displacement takes place, thereby radial and axial distortion takes place in extruding block rubber 8, the purpose that limited post and compression spring 16 are set in gripper shoe 13 left sides is to prevent block rubber 8 infinite extensions, compression spring 16 need reset after enlarging finishes simultaneously, the elastic force of compression spring 16 promotes back-up block and resets, reverse displacement takes place in Internal baffle 6 and outer baffle 11 in the reseting procedure, and then impel block rubber 8 reinstatements, also conveniently withdraw from steel-plastic composite pressure pipe 10, can effectively improve working (machining) efficiency.
