Abstract
The utility model relates to an anti-penetration pipe pressing die which comprises a male die and a female die, wherein the male die and the female die are designed to be a semicircular arc, the radius of the female die is greater than the radius of the male die, the inner arc surface of the female die is uniformly provided with circular arc grooves for eliminating elastic stress, two ends of the inner arc surface are respectively provided with a symmetrical positioning pin hole, a support is arranged in the axial middle of an outer arc surface, a flat plate type connecting seat is welded on the support, and bolt holes are formed at four corners of the connecting seat; the outer arc surface of the male die is uniformly provided with circular arc beads matched with the circular arc grooves in the inner arc surface of the female die, and two ends of the outer arc surface of the male die are provided with cylindrical positioning pins matched with the positioning pin holes in the inner arc surface of the female die. The anti-penetration pipe pressing die solves the problems of pressing of an anti-penetration pipe and elimination of elastic stress, two anti-penetration pipes formed by pressing are engaged after being buckled and are tightly clung to an anti-penetration pipeline, the welding construction is convenient, and the construction efficiency is improved remarkably.
Description
One, technical field
The present invention relates to a kind of oil field prevent the lawless person on petroleum pipeline, gas transmission line and waterline the perforating stolen, steal gas and steal the compacting tool set of the anti-poling of water, solve anti-poling and interlock and weld the problem that misfits with the oil gas water pipeline.
Two, background technology
At present oil, air water are stolen in order to prevent the lawless person in oil field, the anti-poling that one deck electric drill of burn-oning on the oil gas water pipeline is beaten is motionless, the hacksaw saw is motionless, and anti-poling is to make two symmetrical lobe circular arcs by special roll of steel plate to be welded.Because there is certain elastic stress in the steel plate after special, always have and misfit when make-up welds on pipeline, although with the method for striking hoop, weld together, but the anti-poling that is welded into is irregular, not tight with the pipeline laminating, a lot of places produce bulges, do not meet the basic standard of pipeline, and impact is promoted the use of.
Three, summary of the invention
The purpose of this invention is to provide a kind of anti-poling compacting tool set, eliminate the elastic stress that special steel plate exists, standard compliant anti-poling is welded out in compacting.
Technical scheme of the present invention is to realize by following mode:
The present invention includes male model body and master mold body, it is characterized in that master mold body and male model body are designed to semicircular arc, the radius of master mold body is greater than the radius of male model body, evenly be provided with the arc groove of eliminating elastic stress on the intrados of master mold body, be provided with separately a symmetrical shop bolt hole at the intrados two ends, arcwall face axially is provided with a support in middle part outside, is welded with one flat plate formula Connection Block in support, is provided with bolt hole on four angles of Connection Block; Evenly be provided with on the external arcwall face of male model with master mold body intrados on the circular arc shaped rib that is complementary of arc groove, the two ends of male model body profile face be provided with master mold body intrados on the cylindrical shop bolt that is complementary of shop bolt hole, tangent plane at the male model body axially is provided with a support in middle part, be welded with one flat plate formula Connection Block in support, four angles of Connection Block are provided with bolt hole, the Connection Block of master mold body is connected with the piston of moulding press, and the Connection Block of male model body is connected with the work piece platform of moulding press.
The invention solves the compacting of anti-poling and the problem of elimination elastic stress, the anti-poling make-up of two lobes that suppress coincide, and with the anti-drawing-in wire of quilt, fits closely, and welding procedure is convenient, has significantly improved efficiency of construction.

Five, the specific embodiment
, for further disclosing technical scheme of the present invention, below in conjunction with Figure of description, by embodiment, elaborate:
Apply when of the present invention, master mold body 1 is connected on the piston rod of moulding press, male model body 6 is arranged on the mold pressing work piece platform, make two die body up and down corresponding, shop bolt hole 2 is corresponding with shop bolt 7, the special steel plate of anti-poling, and be that the special steel plate level that meets make-up pipeline external surface area size is placed on the male model surface, start moulding press, master mold body 1 is descending, withhold on special steel plate,, with under male model body 6 coordinates, can suppress with the anti-poling of a lobe circular arc of arc fin.Two lobe circular arcs are prevented that poling is to being buckled on oil, air water pipeline in construction, the make-up line coincide, and tight with the pipeline laminating, with the make-up seam welding, namely make the anti-poling that meets the profile standard, prevented that the lawless person is at oil, punching is stolen oil, steals gas and stolen water on the air water pipeline.
