Description
Technical field
The utility model relates to plastic tube processing equipment technical field, the flanging die while especially relating to a kind of polytetrafluoroethyltubing tubing cover flange.
Background technology
Polytetrafluoroethylene (PTFE) has the performances such as good corrosion-resistant, self-lubricating, is usually used in the conveying tubing of corrosive liquids.Polyfluortetraethylene pipe is to adopt Flange to connect in the ducted main connected mode of construction, and this connected mode needs the end of polyfluortetraethylene pipe to form flange.Because polytetrafluoroethylene (PTFE) melt viscosity is large, if it is carried out to flange processing with the plastics flanger of plastic pipe flange processing use, very difficult, particularly in the later stage of flange, flange part is difficult to continue extension.Another difficult point is, for flange, need to carry out thermoplastic to body port, and heat can be transmitted to the non-flange part of polyfluortetraethylene pipe, thereby the performance of non-flange part is had a negative impact.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, and a kind of flanging die of applicable polyfluortetraethylene pipe flange processing is provided.
For this reason, the technical solution of the utility model is a kind of polyfluortetraethylene pipe flanging die, comprises die, the punch that can move downward with respect to die and heating ring pad and heat insulation loop pad; Described die is provided with the annular groove for engaging polyfluortetraethylene pipe workpiece, and annular groove is divided into die top to be positioned at the fixed leg of annular groove and to be positioned at the retainer ring outside annular groove; Heat insulation loop pad is placed on retainer ring, and heating ring pad is placed on heat insulation loop pad, and the internal diameter of heat insulation loop pad and heating ring pad equates with the external diameter of polyfluortetraethylene pipe workpiece, and has electrical heating elements in heating ring pad; Punch is ladder platform structure, ladder platform forms by the base plate of punch with from the lead of base plate lower surface projection, in punch, be provided with electrical heating elements, wherein the fixed leg of lead and die is oppositely arranged, the diameter of lead equates with the internal diameter of polyfluortetraethylene pipe workpiece, and when lead laminating fixed leg, the distance between punch base plate lower surface and heating ring pad upper surface equates with the flange thickness of polyfluortetraethylene pipe workpiece.
By heating ring pad is set, polyfluortetraethylene pipe workpiece needs one end of flange inside and outside to heat, and improves the easiness of its flange; Secondly,, due to heating ring pad being set, the flange part that it can heating tube workpiece, not only makes this part flange can more easily continue extension, has also reduced the obstruction to follow-up formation flange; Be provided with heat insulation gasket ring, stoped the heat of heating ring pad to be transferred to the non-flange part of polyfluortetraethylene pipe workpiece far away, ensured the performance of polyfluortetraethylene pipe.
Preferably, the upper surface of the upper surface of described heat insulation loop pad and the fixed leg of described die is equal.Like this, between heating ring pad and the lead of punch, can, to carrying out inside and outside near the flange corner of polyfluortetraethylene pipe workpiece, converging up and down heating, concentrate thereby overcome near the stress of flange corner, further ensured the performance of polyfluortetraethylene pipe.
Preferably, the thickness of described heating ring pad is 1 ~ 2 times of flange thickness of polyfluortetraethylene pipe workpiece.Blocked uply can produce performance impact to the non-flange part of polyfluortetraethylene pipe workpiece, cross the thin flange part that is difficult to homogeneous heating polyfluortetraethylene pipe workpiece.
Preferably, described heat insulation loop pad is put together by least two heat-insulating cushion blocks.Heat insulation like this gasket ring can be dismantled more conveniently, and then reserves the space of the polyfluortetraethylene pipe workpiece flange part of taking, and the polyfluortetraethylene pipe workpiece that makes to take after flange becomes easy.
Preferably, described heating ring pad is put together by least two heating cushion blocks.Like this, heating cushion block and heat-insulating cushion block all can laterally be dismantled; It laterally can divide and reserve more space for the polyfluortetraethylene pipe workpiece turn-up portion of taking after dismounting, is convenient to take out polyfluortetraethylene pipe workpiece from die.
Thereby for make polyfluortetraethylene pipe workpiece one end swimmingly flange enter the gap between heating ring pad upper surface and punch base plate lower surface, preferably, the lead sidewall of described punch and the base plate lower surface of punch are rounding off.
Thereby for make polyfluortetraethylene pipe workpiece one end swimmingly flange enter the gap between heating ring pad upper surface and punch base plate lower surface, preferably, the madial wall of described heating ring pad and its upper surface are rounding off.
Advantage of the present utility model and beneficial effect are: the utility model polyfluortetraethylene pipe flanging die is applicable to the flange of polyfluortetraethylene pipe workpiece, reduce the flange difficulty of polyfluortetraethylene pipe, overcome the impact of flange on polyfluortetraethylene pipe workpiece performance simultaneously, ensured the performance after polyfluortetraethylene pipe flange.
