Description
(1) technical field
The utility model relates to a kind of device of moulding concetrated pipe.Belong to the pipe fitting processing technique field.
(2) background technology
Concetrated pipe is a place of shunting in the media set, is widely used on oil-refining chemical heating furnace, large-sized boiler and nuclear power, the thermoelectricity jet chimney.Along with the energy, chemical industry, electric power develop rapidly, pair set pipe expense constantly increased in the last few years, and the use field constantly enlarges, and the concetrated pipe production technology is also constantly improved.From traditional reinforced joint welding, to the draw concetrated pipe, hot extrude concetrated pipe till now.The hot extrude concetrated pipe is to adopt local heat on female pipe, make full use of the thermoplasticity of mother metal, adopt the hydraulic power extrusion modling to prop up that mouthful method makes, have disposal molding, it is even to extrude a mouthful wall thickness, and dimensional discrepancy is little, high efficiency, arm height height, Forming Quality is good, and advantage such as save material.But it still has following deficiency:
1, the oil cylinder seat outer rim adopts planar design, and the contact-making surface of oil cylinder seat and concetrated pipe tubing is little, and corresponding lifting surface area is also little, and concetrated pipe deflection of tubing in process is big.
2, heating-up temperature height in the hot extrude process, generally all between 850 ℃～1110 ℃, the hot extrude mould certainly will be with temperature conduction to hydraulic system under this high temperature, and this high temperature causes the bad seals of hydraulic system, has influenced the normal operation of hydraulic system.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, the hot extrude concetrated pipe hydraulic forming device that provides the contact-making surface of a kind of oil cylinder seat and concetrated pipe tubing big, can reduce the operating temperature of hydraulic system.
The purpose of this utility model is achieved in that a kind of hot extrude concetrated pipe hydraulic forming device, comprise steel pipe, oil cylinder, ejector pin of die set and mould, oil cylinder places in the steel pipe, the piston rod center fixed of oil cylinder is provided with an ejector pin of die set, the ejector pin of die set top is fixedly connected with a mould, oil cylinder bottom is fixed on the oil cylinder seat, and the arc surface that matches with the steel pipe internal face is arranged in described oil cylinder seat two sides; Be provided with chute in centre, oil cylinder seat bottom, corresponding to this chute, have a guide rail to be fixedly set in centre, steel pipe inwall bottom along the steel pipe length direction, this guide rail and described chute are slidingly fitted.
The utility model hot extrude concetrated pipe hydraulic forming device; described piston rod is arranged to hollow structure; described ejector pin of die set is arranged at piston rod central authorities, is provided with a ring-type spacer between described piston rod internal perisporium and piston rod periphery wall, is provided with cooling protection liquid in this ring-type spacer.
The beneficial effects of the utility model are:
1, the utility model hot extrude concetrated pipe hydraulic forming device, adopted the design of oil cylinder seat outer margin arc-surface, what adopt the main consideration of cambered surface design is the distortion of concetrated pipe tubing process, with pressing close to pipe material inner wall, increase contact-making surface and increase lifting surface area, at utmost controlled the distortion of process.
2, the utility model hot extrude concetrated pipe hydraulic forming device is provided with cooling protection liquid in piston rod, can reduce the operating temperature of hydraulic system, the normal operation of protection hydraulic system.
