Abstract

The utility model relates to a metallic multiple tube end plastic layer stripper, which belongs to a cutting tool used for stripping an outer plastic tube which is arranged at the end of a metallic multiple tube, so that the metallic multiple tube is adhesively connected with novel tube fittings conveniently. The utility model is characterized in that the stripper is composed of internal and external steel tube sleeves, a cutter, and a scraper, wherein, the steel tube sleeves are mutually imbedded and welded together, and electrical heating wires are arranged in a mesial interlayer between the steel tube sleeves; the cutter is vertical to a multiple tube axial cord and installed at a transversal surface, and the scraper is installed on the wall of the internal steel tube sleeve and is parallel to the multiple tube axial cord. The utility model can realize the adheres connection by matching with the novel tube fittings, and has the advantages of simple structure, convenient operation, without great energy consumption, small volume, light weight, portability, firm connection, good leak tightness, etc.

Description

Metal composite tube end plastic layer stripper

A kind of metal composite tube end plastic layer stripper belongs to the cutting tool technical field, and the outer layer plastic tube that is mainly used in the metal composite tube end divests, and makes it to expose metal tube, so that with novel pipe fitting the mutual bonding connection of metal composite pipe is got up.

In the prior art, metal (comprising aluminium, steel, stainless steel, copper etc.) generally all is to use by metal casting processing to connect by the common pipe fitting that is threaded when plastic composite pipe interconnects.This connected mode one is that the coarse heaviness of pipe fitting had both been wasted raw material, not attractive in appearance again, the 2nd, in machining screw on the outer layer plastic tube since between plastics and the metal hardness and the coefficient of expansion etc. all different, be difficult to cooperatively interact, therefore cause connecting not firm, poorly sealed, the stripped thread uncoupling takes place often, run, emit, phenomenon such as leakage.

It is a kind of simple in structure that the purpose of this utility model is to provide, easy to use, volume is little, in light weight, easy to carry, cost is low, can be easy to the outer layer plastic tube of metal composite tube end divested expose metal tube, so that cooperate new-type advanced person's pipe fitting to take the bonding mode of metal tube and metal tube that metal composite pipe is interconnected firmly, the metal composite tube end plastic layer stripper of good seal.

Physical characteristic according to electric heating and cutting basic principle and plastics, at existing questions in the prior art, basic design of the present utility model is: need remove its length of end suit of outer layer plastic tube and isometric (being generally about 50mm of this section outer layer plastic tube that need remove at metal composite pipe, can suitably extend or shortening according to the pipe diameter size), the double-deck pipe box that is welded by inside and outside two-layer steel pipe suit therebetween electrical heating wire, be to install one perpendicular to the axis of multiple tube on the boundary line of the part peelled off of the part that need peel off of metal composite pipe outer layer plastic tube and not needing to make the cutting blade that circular motion and adjustable this section plastic tube in order to being entangled of radial distance cut away from the integral plastics pipe along plastic tube outer wall in its inner end, install one more within it in the saturating groove of offering on the wall of layer steel pipe of dress cutter and parallel with the multiple tube axis and adjustable in order to will be heated the wing that softens and wiped off by the plastic tube that cuts off from the integral plastics pipe.Can cut and be wiped off from the integral plastics pipe being heated this section of softening plastic tube end when external force (move as clamping manpower with the heat insulation pipe vice of tape insulation, or insert once thoroughly doing away with that the heat insulation handle of edge is moved with hand etc. at fluting on the outer layer pipe wall of this bilayer sleeve) effect lower edge is divested plastic tube and rotates when this bimetallic tube is enclosed within.Thereby realization purpose of design.

Metal composite tube end plastic layer stripper described in the utility model, it is characterized in that this stripper monnolithic case is a tubulose, it leaves interlayer between the two by inside and outside mutual sheathing and the interior steel pipe socket 5 that offers the saturating groove of dress cutter (i.e. the slit that communicates with inner chamber) that parallels with axis on the outer steel pipe socket 1 of electrical heating wire 2 of tape insulation layer and its wall is housed in it is welded, and on its end (being the inner end when the using) cross section cutting knife 4 perpendicular with the composite pipe axis is housed also, the scraper 3 isometric with interior steel pipe socket 5 is housed in the above-mentioned saturating groove of its interior steel pipe socket 5.

They all can radially move above-mentioned cutting knife 4 and scraper 3 so that regulate blade and by the distance between the plastic tube outer wall that divests.

The utility model has the advantages that: simple in structure, safety easy to use, volume is little, in light weight, easy to carry, cost is low, does not expend the energy, can be easy to the outer layer plastic tube of metal composite tube end is divested the metal tube that exposes the middle level with the hand reinforcing, take the bonding mode of metal tube and metal tube that metal composite pipe is interconnected with the pipe fitting that cooperates new-type advanced person, and be connected firmly long service life, favorable sealing property can fundamentally stop to run in the pipeline phenomenons such as emitting leakage.

Accompanying drawing is that one of the utility model most preferred embodiment assembling back is whole perpendicular to the cross-sectional section structure schematic diagram of axis.

Further describe architectural feature of the present utility model as follows with most preferred embodiment in conjunction with the accompanying drawings: on long 50mm diameter 33mm and its tube wall, have the skin that parallels to the axis and manage isometric interior steel pipe socket 5 for the saturating groove used of dress cutter again suit length also be the outer steel pipe socket 1 of 53mm for the 50mm diameter, the axis of the two coincides, pack in its interlayer 300w electrical heating wire 2 of tape insulation layer and the back that is connected with additional power source welds together the two at the two ends of two pipe boxes, install one the cutting knife 4 that can radially move perpendicular to tubing axis and band roll adjustment screw so that along with the needs of feed at an end of two pipe boxes (being divested and need to keep between the position of outer layer plastic at need during use), the screw that steel pipe socket 1 outside available the passing is installed in the saturating groove on above-mentioned interior steel pipe socket 5 tube walls again is the scraper 3 of roll adjustment radially.Elder generation treats firmly to move after it softens this stripper elder generation to the multiple tube end plastic layer heating of being entangled and by cutting knife 4 this section is heated softening plastic pipe layer cut-out after switching on, and then from level to level it is divested by scraper 3.

Change as present embodiment:

1, the material of inside and outside pipe box can change stainless steel etc. into, and their length and diameter can be along with being shelled

Remove the diameter of tubing and change;

2, the wattage of electrical heating wire can suitably be adjusted according to actual needs;

3, the radially mobile regulative mode of cutting knife and scraper can change arbitrarily.
