Abstract
The invention belongs to a processing method of metal pipes, in particular to a manufacturing method of a high-bonding-force bimetal composite pipe, which is suitable for manufacturing various different metal composite pipes. A technology for manufacturing the bimetal composite pipe with high binding force includes such steps as rolling an internal pipe by a cold roller to form a concave-convex surface, machining several radial slots and two axial slots on the roller, sleeving the internal pipe in external pipe, sleeving the internal pipe on mandrel, and rolling by roller to obtain the finished product.
Description
Technical field
The invention belongs to the processing method of metal pipe material, more precisely is a kind of preparation method of high-bond composite bimetal pipe, is suitable for making various different metal composite pipes.
Background technology
Multiple tube is the inside and outside two-layer tubing that is formed by combining closely by the metal of unlike material, make by stainless steel and carbon steel pressing as comparatively common stainless steel composite pipe, the preparation method of this composite pipe is that corrosion resistant plate is cut into bar, twist in the carbon steel tubing outer wall, weld with the weldering of argon fox in the slit, drawing more afterwards, alignment, polishing is become a useful person.The multiple tube cost height of Sheng Chaning in this way, the interlayer adhesion is poor.
Summary of the invention
Given this, the object of the present invention is to provide a kind of preparation method of high-bond composite bimetal pipe, the composite bimetal pipe interlayer adhesion that adopts the present invention to make is strong, and endoporus and surface smoothness height are suitable for making the tubing of various specific demands such as bearing shell.
Purpose of the present invention realizes by following technical measures: the preparation method of high-bond composite bimetal pipe, adopt the roll-type cold pilger mill, and select roll and plug according to the inside and outside footpath of required tubing, at first:
1, interior pipe blank surface treatment as pickling, is closed in the saponification;
2, with the breaking down under special interior pipe bloom roll of interior pipe, the interior tube-surface after the breaking down is convex-concave surface;
3, said special interior pipe bloom roll, the some radial grooves of processing and two axial notches on roll;
4, the interior pipe box after the breaking down is gone in the outer tube;
5, interior pipe box is on plug, and inner tube diameter and plug fit clearance are 0.2-1mm;
6, rolling by roll-type tube rolling system, get manufactured goods.
The interior pipe outside that just shuts out will produce 9 fins along axis direction, wherein have 3 to be to be formed by three roll gaps to each other.And the equidistant fin that axial segmentation occurs is then formed by axial notch 2 extruding.
The inner tube face that breaking down is come out and outer surface such as Fig. 3, shown in Figure 4.Be similar to the screw-thread steel that building trade is used.
Adopt the method for the present invention can processing stainless steel/carbon steel, aluminium/carbon steel, aluminium/carbon steel/various different metal composite pipes such as aluminium, composite pipe by processing and fabricating of the present invention, the interlayer adhesion is strong, and axially with radially anti-pulling-out force height, surfaces externally and internally is highly polished.
Description of drawings
The structure of internally managing bloom roll in conjunction with the accompanying drawings is described further.
Fig. 1 is an interior pipe bloom roll structure chart among the present invention.
Fig. 2 is composite pipe structure figure among the present invention.
Fig. 3 is an inner tube face structure chart.
Fig. 4 is interior tube-surface structure chart.
Wherein pipe, 5 outer tubes in 1 roll, 2 axial notches, 3 radial grooves, 4.
The specific embodiment:
Embodiment 1, processing and fabricating steel/copper multiple tube, and steel adopt 20 carbon steel, copper material adopts the Qsn6.5-0.1 phosphor bronze, select for use the LD-30 three-roll pipe mill of Ningbo lathe head factory production earlier 20 carbon steel tubing pickling to be derusted, in saponification, close standby, again with the copper pipe breaking down, the copper pipe outer surface is convex-concave surface after bloom roll system, carbon steel tubing is enclosed within on the copper pipe, copper pipe is enclosed within on the plug again, and copper pipe internal diameter and plug fit clearance are 0.5mm, rolling through three roller cold pilger mills, get steel/copper composite pipe.
Claims (1)
1, a kind of preparation method of high-bond composite bimetal pipe adopts the roll-type cold pilger mill, selects roll and plug according to the inside and outside footpath of required tubing, it is characterized in that:
(1), interior pipe blank surface treatment;
(2), with the breaking down under special interior pipe bloom roll of interior pipe, the interior tube-surface after the breaking down is convex-concave surface;
(3), said special interior pipe bloom roll, processing some radial grooves and two axial notches on roll;
