Embodiment
In view of in the prior art, in actual applications, needing to carry out chamfering to sleeve pipe in drag-line manufacturing process.Common is double
During layer multiple tube is generally circular two layers, chamfering, cause internal lining pipe to rotate for two layers due to inside and outside two layers of bonding force not enough
Slide, be that post-processing causes difficulty.The utility model is respectively provided with the contact surface of bimetallic tube is mutually matched the convex of occlusion
Rise or be recessed, so as to be that the rotational slide and axially opposing slip between two layers of tubing are avoided when inner and outer pipes are nested, it is ensured that
In traction process will not bimetallic tube will not slip.
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
As shown in figure 1, the specific embodiment of the utility model one discloses a kind of two-layer compound internal lining pipe pipe for drag-line
Material caliper mounting bracket, it includes：Inner tube 1, its lateral wall includes polygon projection 11；Outer tube 2, its madial wall includes many
Side shape depression 21, the polygon depression 21 is matched with polygon projection 11；When the inner tube 1 is nested into the outer layer
In pipe 2, the lateral wall of the inner tube 1 and the madial wall of the outer tube 2 are intermeshed.
Process to be formed by way of inner tube 1 and outer tube 2 are by raised and depression mutually " occlusion ", it is therefore prevented that two layers
Rotational slide and axially opposing slip between tubing, it is ensured that in traction process will not bimetallic tube will not slip.
In the utility model embodiment, the lateral wall of the inner tube 110 be it is raised with dentation or trapezoidal shape, it is described
The madial wall of outer tube 120 has corresponding dentation or trapezoidal shape depression.
In the utility model embodiment, described raised 111 or 121 height of being recessed be 0.1mm-0.5mm, quantity is
15-40.
In the utility model embodiment, the inner tube 110 is polyfluortetraethylene pipe, and the outer tube 120 is engineering
Plastic tube.
Further detailed description is done to the utility model with reference to embodiment, but of the present utility model realizes condition bag
Containing example condition but not limited to this.
Fig. 1 is that internal layer is jagged compound lining pipe schematic diagram, wherein PTFE inner tubes 110, with dentation, with plastics
It is interlocked after outer tube 120 is coated.Dentation is highly 0.3mm, altogether 20 tooth.
Fig. 2 is the compound lining pipe schematic diagram that internal layer is trapezoidal shape, and wherein PTFE inner tubes 210 are raised with trapezoidal shape
211, form trapezoidal shape depression 221 with the coated rear inner side of plastic outer layer pipe 220 and be interlocked with trapezoidal shape projection 211.Ladder
Shape height is 0.3mm, 20 altogether.
Fig. 3 is that internal layer is that outside is dodecagonal compound lining pipe schematic diagram, wherein PTFE inner tubes 310, its outside
For twelve edge convex 311, form twelve edge annular 321 with the coated rear inner side of plastic outer layer pipe 320 and stung with twelve edge convex 311
It is combined.
Refer to Fig. 4, the utility model embodiment also provides a kind of manufacture method of two-layer compound internal lining pipe, it include with
Lower step：
Step S110 uses the mould cold-extruded with special shape to go out polyfluortetraethylene pipe, its lateral wall is had polygon
Inner tube is made after projection, sintered cooling and shaping；
Step S120 coats engineering plastics in the inner tube and is processed into outer tube, and two-layer compound internal lining pipe is made.
Specifically, due to PTFE characteristic, processed using the metallurgical mode of like powder, it is impossible to moulded with conventional thermoplastic
The processing mode production of material.Therefore need first to go out PTFE internal layers using the mould cold-extruded of special shape, make it have polygon convex
Rise, such as dentation；Two layers of compound lining pipe is processed into by the mode of coating engineering plastics again.Because the engineering plastics of outer layer are
Melting extrusion, with preferable mobility, can be filled between the dentation of internal layer in plastic-coated, and class, can be with mechanical " occlusion "
Prevent rotational slide and axially opposing slip.
