Abstract
The utility model relates to a positioning device for improving mould pressing concentricity of a steel lined polytetrafluoroethylene pipe and pipe fittings. A positioning cushion is added at one end of a steel pipe; the top of the positioning cushion is arranged between a steel pipe and a mould core; one end of the mould core is inserted into an inner hole of the positioning cushion. The concentricity of the steel pipe and the mould core is ensured; a step is arranged outside the positioning cushion so as to prevent leakage of polytetrafluoroethylene powder in powder filling; the positioning cushion is divided into three equal parts on the circumference, so that the assembly and disassembly are convenient; in mounting, a cover plate is arranged at the bottom of the positioning cushion, a pressing ring is arranged on the outer circumference of the positioning cushion, and the cover plate and the pressing ring are connected onto one flange through bolts; the leakproofness is good, and the operation is simple.
Description
Technical field
The utility model relates to steel lining polyfluortetraethylene pipe mold pressing field, especially improves the positioner of steel lining polyfluortetraethylene pipe and pipe fitting mold pressing concentricity.
Background technology
Steel lining polyfluortetraethylene pipe and pipe fitting carry out flange group to time, because circle of steel tube and coordinating of flange endoporus exist certain gap, cause the endoporus decentraction of flange and steel pipe, in the time carrying out mold pressing powder filling, adopt flange location can cause core rod and steel tube inner hole decentraction, gap is between the two irregular, add that steel pipe and core rod all exist certain bending, after mold pressing powder filling, teflon lined layer is prone to the phenomenon of the even disconnected powder of wall thickness deviation, affects product quality and service life.
Summary of the invention
The purpose of this utility model is to solve existing steel lining polyfluortetraethylene pipe and pipe fitting carrying out backing layer in mold pressing powder filling process and occur the phenomenon of the even disconnected powder of wall thickness deviation, designs raising steel lining polyfluortetraethylene pipe that a kind of simple in structure, processing ease, yield rate are high and the positioner of pipe fitting mold pressing concentricity.The technical solution of the utility model is so to realize:
Improve the positioner of steel lining polyfluortetraethylene pipe and pipe fitting mold pressing concentricity, comprise steel pipe and as for the flange at its two ends be located at the core rod in steel pipe, one end of steel pipe is provided with the locating pad with endoporus, described locating pad section is " protruding " font with endoporus, locating pad top is located between steel pipe and core rod, one end of described core rod is placed in the endoporus of locating pad, flange outside in nearly locating pad one end is provided with cover plate, the bottom of described locating pad is located between flange and cover plate, and described locating pad is spliced by the three equal parts of decile on circumference.
As preferably, the length that described locating pad stretches in steel pipe is 7～13mm.
As preferably, the top external diameter of described locating pad is than the little 0.5～1mm of pipe diameter.
As preferably, in described locating pad, the diameter of endoporus is than the large 0.5～1mm of the external diameter of core rod.
As preferably, the excircle of the locating pad between described flange and cover plate is provided with trim ring.
The raising steel lining polyfluortetraethylene pipe of the utility model design and the positioner of pipe fitting mold pressing concentricity, set up a locating pad in steel pipe one end, the top of locating pad is placed between steel pipe and core rod, and insert in the endoporus of locating pad one end of core rod, ensure the concentricity of steel pipe and core rod, locating pad outside is provided with step, the leakage of polytetrafluoroethylene (PTFE) powder while preventing powder filling, whole device is divided into three equal parts on circumference, be convenient to handling, when installation, locating pad bottom is provided with cover plate, excircle is provided with trim ring, be connected on flange with bolt, good airproof performance, simple to operate.
