Light crimping machine for continuous reinforced plastic composite pipe
Technical field
The invention belongs to the design of light crimping machine for continuous reinforced plastic composite pipe.
Background technology
Connection between the petroleum pipeline of oil field is the key problem in technology that each production flow line producer at first must solve always, and connection bad will be revealed, the undergauge phenomenon appears in interior caliber herein.The special tubing of OCIMF of Britain shand company professional production uses up the full-embedded type tube connector, its front and rear panel is a triangular structure, and have a planker, therefore, withhold that the machine overall volume is big, weight is big, can not frequently move, be unsuitable for site operation, particularly when the work of job site be in the salt-soda soil, marshland or in ground, rice field, environment very severe, and be again under the situation of excavating operation in the hole, do not allow to withhold long-pending excessive, the preponderance of body, therefore, for adapting to the actual conditions needs of job site, people further investigate light crimping machine.
Summary of the invention
The purpose of this invention is to provide a kind of light crimping machine for continuous reinforced plastic composite pipe.
The present invention for the perfect piecing devices of withholding, improve efficiency of construction, reduce construction cost, the present invention blocks continuous reinforced plastic composite pipe in the circle of school, and and then the mobile handle of oil cylinder piston bar is withheld fitting sleeve on continuous reinforced plastic composite pipe, unclamp subsequently and draw horse chucking oil cylinder, bloated support set in installing, interior bloated support set has gap, and the oil cylinder piston bar pulls back, the head that expands in making is deviate from from withhold joint, and operation expands in finishing; The oil cylinder piston bar promotes to withhold joint then, finishes outer button operation by outer buckling die piece.
The present invention at first draws the Malaysia to finish the school circle with split type hydraulic pressure, school circle clamping device is an oval frame, the sheathed multiple tube in the middle part of this framework, the long axis direction two ends of this framework respectively offer a screwed hole, this screwed hole links to each other with connecting rod, the other end of connecting rod links to each other with the bolt hole of oil cylinder front end-plate, respectively be provided with one on its side, long axis direction two ends and draw house oil cylinder holder, draw house oil cylinder holder to fix with four hexagon-headed bolts respectively, two are drawn the endoporus of house oil cylinder holder is trapezoidal thread, each settles one to draw the house oil cylinder, the front end of oil cylinder piston bar has cannelure, make the end form circlip for shaft, a compound gland on circlip, gland is first-class to be arranged with four screw holes, the plane of circular arc head clamp is relative with gland should four screwed holes, fix with hold-down screw, the diameter of bore of gland is less than circular arc head clamp counter bore hole diameters, the circlip for shaft of oil cylinder piston bar front end directly inserts circular arc head clamp counterbore, the endoporus of oval frame becomes the conical surface and the conical surface to be complementary outer buckling die plate, the thickness of template is greater than the thickness of oval frame, the size of screwed hole that respectively has four five equilibriums of a bolt hole and conical surface edge in the middle of the pressing plate of four rectangular L types matches, pass through set bolt, pressing plate is fixed outer buckling die piece, oil cylinder front end-plate central authorities have a circular hole, circular etc. are arranged with four screwed holes, and is furnished with circular fixed cover, circular fixed cover is first-class to be arranged with four bolt holes, corresponding with the screwed hole on the oil cylinder front end-plate, use bolting, oil cylinder front end-plate central aperture and oil cylinder piston bar external diameter are complementary, one side seam of fixed cover external diameter and interior bloated cushion cover coincide, the interior cushion cover two ends of expanding are seam, have a circular hole in the middle of two seams, in expand cushion cover other end seam with withhold the joint end anastomosis, the end of oil cylinder piston bar is processed with internal thread and external screw thread, internal thread links to each other with the external screw thread of pull bar, the pull bar two ends are processed with external screw thread, the other end links to each other with the internal thread of interior bloated head, the interior desk-top centre of circular cone of expanding head is processed with internal thread hole, and the external screw thread of its internal thread and pull bar links to each other;
Support set one end that expands in cylindrical has seam, the other end has boss, and have a gap along axis direction, the width of gap is greater than the oil cylinder piston shank diameter, outer button positioning sleeve one end has internal thread hole, the other end has boss, is threaded an end in hole and the external screw thread of oil cylinder piston bar and links to each other, and has an end of boss and withholds the joint end anastomosis.
Withhold joint, form by a hollow tube and the round jacket that is fixed on this hollow tube cylindrical, be provided with the gap of plant multiple tube pipe thickness between the internal diameter of this round jacket and the external diameter of hollow tube, and the corresponding engaging tooth that is provided with of the inside diameter surface of the external diameter surface of hollow tube and round jacket;
The interior head that expands is a bullet, and an end of its minor diameter inserts in the hollow tube, is connected with the oil cylinder piston bar by pull bar;
Multiple tube inserts withholds joint, makes the hollow tube external diameter surface engaging tooth relative with the round jacket inside diameter surface sting tight multiple tube by the head that expands in the pulling of oil cylinder piston bar.
Outer buckling die piece drives outer button positioning sleeve by the oil cylinder piston bar and promotes to withhold joint, passing outer buckling die piece formation withholds, make " tooth " on the round jacket internal diameter along with the process of withholding, be embedded into the external diameter surface of continuous reinforced plastic composite pipe once more, reinforce the effect of sealing, chucking.
Light crimping machine of the present invention is simple in structure, and is easy to operate, and the overall structure compact dimensions is reasonable, convenient transportation, installing tache crimp head are quick, this is more suitable for excavating in open-air marshland or the ground, rice field the repairing operation in the hole, and cheap for manufacturing cost, has extensive economy, applied value.
