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.
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 flange mould, comprises punch, die and heating cushion; Described punch upper surface is provided with shoulder hole, and the center of shoulder hole is provided with lead, and the external diameter diameter of lead equates with the internal diameter of polyfluortetraethylene pipe workpiece, and the inner bottom part of lead is provided with electrical heating elements; Heating cushion has two at least, inside there is electrical heating elements, heating cushion is removably fastened on the ladder of shoulder hole, and form loop configuration, the diameter of bore of the loop configuration of heating cushion composition equates with the external diameter of polyfluortetraethylene pipe workpiece, and distance between the bottom surface of heating cushion and the inner bottom surface of punch shoulder hole equates with the flange thickness of polyfluortetraethylene pipe workpiece; Described die is the tubular construction with endoporus, and endoporus and the lead of die are slidably matched, and the wall thickness of die equates with the wall thickness of polyfluortetraethylene pipe workpiece.
By heating cushion 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 cushion 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 inhibition to follow-up formation flange; Again, because heating cushion amalgamation forms loop configuration, after flange is finished, each heating cushion can be dismantled easily, has avoided arranging the raising that heating cushion causes operation easier; Improved the easiness of polyfluortetraethylene pipe flange from above-mentioned three aspects.
Because heating cushion can be dismantled easily, in order further to avoid the polyfluortetraethylene pipe workpiece on lead in matched moulds process outwards to expand, polyfluortetraethylene pipe workpiece is moved downward swimmingly, and preferably, the upper surface of described heating cushion is equal with the upper surface of described lead; And only in the bottom of heating cushion, described electrical heating elements is set.
Thereby for make polyfluortetraethylene pipe workpiece one end swimmingly flange enter between heating cushion bottom surface and the inner bottom surface of punch shoulder hole, preferably, the lead sidewall of described punch and the shoulder hole bottom surface of punch are rounding off.
Thereby for make polyfluortetraethylene pipe workpiece one end swimmingly flange enter between heating cushion bottom surface and the inner bottom surface of punch shoulder hole, preferably, the madial wall of described heating cushion and its lower surface are rounding off.
Advantage of the present utility model and beneficial effect are: the utility model polyfluortetraethylene pipe flange is applicable to polyfluortetraethylene pipe flange with mould, have reduced the flange difficulty of polyfluortetraethylene pipe.And in flange, effectively ensure the performance of polyfluortetraethylene pipe.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
The utility model is a kind of polyfluortetraethylene pipe flange mould, as depicted in figs. 1 and 2, comprises punch 1, die 2 and heating cushion; Punch 1 upper surface is provided with shoulder hole 11, and shoulder hole 11 center is provided with lead 12, and the external diameter diameter of lead 12 equates with the internal diameter of polyfluortetraethylene pipe workpiece, and the inner bottom part of lead 12 is provided with electrical heating elements 13; Heating is lined with two, be respectively the first heating cushion 3 and the second heating cushion 4, in the first heating cushion 3 and the second heating cushion 4, be respectively equipped with electrical heating elements 31,41, the first heating cushion 3 and the second heating cushion 4 are removably fastened on the ladder of shoulder hole 11, and form loop configuration, the diameter of bore of the loop configuration of first, second heating cushion 3,4 compositions equates with the external diameter of polyfluortetraethylene pipe workpiece, and distance between the bottom surface of first, second heating cushion 3,4 and the inner bottom surface of punch 1 shoulder hole 11 equates with the flange thickness of polyfluortetraethylene pipe workpiece; Die 2 is for having the tubular construction of endoporus 21, and endoporus 21 and the lead 12 of die 2 are slidably matched, and the wall thickness of die 2 equates with the wall thickness of polyfluortetraethylene pipe workpiece.Its using method as shown in Figure 3 and Figure 4.
Thereby for make polyfluortetraethylene pipe workpiece one end swimmingly flange enter between heating cushion 3 bottom surfaces and the inner bottom surface of punch 1 shoulder hole 11, preferably lead 12 sidewalls of punch 1 and shoulder hole 11 bottom surfaces of punch 1 are rounding off, and the madial wall of first, second heating cushion 3,4 and its lower surface are rounding off.
Because first, second heating cushion 3,4 can be dismantled easily, polyfluortetraethylene pipe workpiece on lead 12 in matched moulds process outwards expands, polyfluortetraethylene pipe workpiece is moved downward swimmingly, and preferably the upper surface of first, second heating cushion 3 is equal with the upper surface of lead 12.In addition, electrical heating elements 31,41 only needs to be arranged on the inner bottom part of first, second heating cushion 3,4, is arranged at the inner bottom part of lead 12 due to electrical heating elements 13 simultaneously, and that can avoid like this polyfluortetraethylene pipe workpiece can produce distortion without flange place.Electrical heating elements 13,31,41 can be resistance wire.
In addition, the piece number of heating cushion can also be increased, as long as make on its ladder that is removably fastened on shoulder hole 11, and the loop configuration that diameter of bore equates with the external diameter of polyfluortetraethylene pipe workpiece can be formed.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
