Technical field
The present invention relates to tubular object extruding technical field, specifically a kind of plastic pipe necking rounding device.
Background technology
Tubing is exactly the material for making pipe fitting.Different pipe fittings is directly determined with different tubing, the quality of tubing
The quality of pipe fitting.Multiplex such tubing such as architectural engineering, power plant, chemical plant, including：PPR pipe, pvc pipe, UPVC pipes, copper pipe,
Steel pipe, fibre pipe, multiple tube, galvanized pipe, flexible pipe, reduced pipe, water pipe.Tubing be architectural engineering necessary to material, conventional has
Feed pipe, drainpipe, gas pipe, steam heating pipe, electric conduit, rain pipe etc..With the development of science and technology, house decoration is used
Tubing also experienced plain cast iron pipe → pipe of cement → (concrete reinforced pipe, asbestos-cement pipe) → ductile iron pipe, zinc-plated
The development course of steel pipe → plastic tube and PAP.
In recent years, plastic conduit is a series of excellent with its light weight, corrosion resistance, install convenient etc. as a kind of novel tube
One of gesture is widely applied in China, and the main substitute as traditional piping material.But in the mistake processed or use
The unavoidable situation that tubing necking nozzle distortion occurs in journey, to using bringing difficulty, or even causes the tubing cannot to use, so
The mouth of pipe for deforming how tubing necking restores to the original state and becomes current urgent problem, and it is universal that company produces tubing at present
There are problems that the mouth of pipe shrinks so that the out-of-roundness of tubing necking is significantly honest so that shrinkage factor substantially increases, no matter from mechanical property
Still pipeline welding docking aspect can all impact, cause pipeline to be docked between critical point when being mutually butted and weld tired
Difficulty, often beyond national regulations, it is defective work to be incorporated into, reduces the quality of production, increased the disqualification rate of tubing production,
Productivity effect and production quality are reduced, inconvenience is used.
The content of the invention
Regarding to the issue above, the invention provides a kind of plastic pipe necking rounding device, solve tubing and produce its pipe
Mouth shrinks generally existing deformation, the increase of mouth of pipe out-of-roundness so that pipeline welding or docking difficulty so that shrinkage factor substantially increases,
Beyond national regulations, the increased problem of disqualification rate is caused.
To achieve the above object, technical scheme is specific as follows：
A kind of plastic pipe necking rounding device, including outer ring 1, spreading mechanism, support 4, numerical control operating display 5；Its
It is characterised by：Described outer ring 1 is fixedly installed on described support 4, and the described interior setting spreading mechanism in outer ring 1；
Described spreading mechanism includes four hydraulic pressure telescopic rods 2, four full circle plates 6, fixing axles 3, wherein described fixation
Axle 3 is connected with support 4, and the described periphery of fixing axle 3 is uniformly arranged four hydraulic pressure telescopic rods 2, and described full circle plate 6 is respectively provided with
A full circle ring is constituted in four full circle plates 6 on four described telescopic ends of hydraulic pressure telescopic rod 2 and described；Described number
Control operation display 5 is connected with four described hydraulic pressure telescopic rods 2.
One of which plastic pipe necking rounding device, a diameter of the 50 of the full circle ring that four described full circle plates 6 are constituted
Millimeter.
The beneficial effects of the invention are as follows：
The present invention solves tubing and produces the deformation of its mouth of pipe contraction generally existing, the increase of mouth of pipe out-of-roundness so that pipeline is welded
Connect or dock difficulty so that shrinkage factor substantially increases, beyond national regulations, cause the increased problem of disqualification rate, its four whole
Plectane 6 is made using four semicircle mould steel materials, and constitute a full circle ring for smooth outer surface, its full circle ring it is a diameter of
50 millimeters, numerical control operating display 5 is connected with four described hydraulic pressure telescopic rods 2, can control four expansions of hydraulic pressure telescopic rod 2
Contraction speed, distance, pressure, and can direct measurement, show mouth of pipe out-of-roundness, and can adjust to greatest extent, play pipe
The full circle purpose of mouth, improves tubing necking full circle efficiency, and tubing necking deformation causes tubing in solving tubing production process
Ropy problem, improves the qualification rate that tubing produces its mouth of pipe, improves the tubing quality of production, practical reliable.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Wherein, outer ring 1, hydraulic pressure telescopic rod 2, fixing axle 3, support 4, numerical control operating display 5, full circle plate 6.
Specific embodiment
The present invention is further described with reference to specification drawings and specific embodiments：
Embodiment 1, as shown in figure 1, a kind of plastic pipe necking rounding device, including outer ring 1, spreading mechanism, support 4,
Numerical control operating display 5；Described outer ring 1 is fixedly installed on described support 4, and described interior setting the in outer ring 1 struts machine
Structure；
Described spreading mechanism includes four hydraulic pressure telescopic rods 2, four full circle plates 6, fixing axles 3, wherein described fixation
Axle 3 is connected with support 4, and the described periphery of fixing axle 3 is uniformly arranged four hydraulic pressure telescopic rods 2, and described full circle plate 6 is respectively provided with
A full circle ring is constituted in four full circle plates 6 on four described telescopic ends of hydraulic pressure telescopic rod 2 and described；Described number
Control operation display 5 is connected with four described hydraulic pressure telescopic rods 2.
One of which plastic pipe necking rounding device, a diameter of the 50 of the full circle ring that four described full circle plates 6 are constituted
Millimeter, is conducive to reaching the purpose of mouth of pipe full circle, improves full circle efficiency.
The present invention when in use, the mouth of pipe of tubing is stretched into outer ring 1 so that spreading mechanism is in tube opening, so
Display 5 is operated to control four hydraulic pressure telescopic rods 2 to be stretched by operating numerical control afterwards, while four full circle plates 6 are with four
The stretching, extension of hydraulic pressure telescopic rod 2 and tube opening is extruded, i.e., the full circle ring of four full circle plates 6 composition in tube opening not
It is disconnected to strut and the tube wall to tube opening is extruded, while the tube wall of tube opening out-of-roundness while full circle central shoring is opened subtracts
It is small, tube opening is carried out into full circle, it is easy to use, it is easy to operate, improve operating efficiency.
The present invention solves tubing and produces the deformation of its mouth of pipe contraction generally existing, the increase of mouth of pipe out-of-roundness so that pipeline is welded
Connect or dock difficulty so that shrinkage factor substantially increases, beyond national regulations, cause the increased problem of disqualification rate；
Its four full circle plates 6 are made using four semicircle mould steel materials, and constitute a full circle ring for smooth outer surface,
A diameter of 50 millimeters of its full circle ring, numerical control operating display 5 is connected with four described hydraulic pressure telescopic rods 2, can control four
Expansion contraction speed, distance, the pressure of individual hydraulic pressure telescopic rod 2, and can direct measurement, display mouth of pipe out-of-roundness, and can be maximum
The adjustment of limit, plays the full circle purpose of the mouth of pipe, improves tubing necking full circle efficiency, solves tubing in tubing production process
Necking deformation causes the problem of pipe workpiece quality difference, improves the qualification rate that tubing produces its mouth of pipe, improves the tubing quality of production,
It is easy to use, it is easy to operate, operating efficiency is improve, it is practical reliable.
