The present invention is achieved in that a kind of organic flexible pipe of high rigidity with metal frame, comprise metal frame and organic material, described organic material envelopes metal frame, described metal frame inner framework and outer skeleton two-part are formed, described inner framework and outer skeleton are all that spirality forms by the wire rod of rolling-forming is curling, inner framework is contrary with the Hand of spiral of outer skeleton, and outer skeleton is sleeved on outside inner framework.
The transverse section of described inner framework and outer skeleton is rectangle.
Certain interval is left between described inner framework and outer skeleton.
A kind of organic flexible pipe metal frame manufacture method, set the tensile strength of required wire rod, transverse section width and cross sectional thickness, carry out a tension adjustment according to above-mentioned three reference order, width adjustment, the adjustment of secondary tension, a thickness adjustment, secondary width adjustment, a secondary thickness adjust, obtain wire rod; Then obtained wire coil song is obtained required spirality metal skeleton to finished product curling barrel.
The described idiographic flow be rolled according to three reference order is as follows:
S1: tension adjustment, this rolling makes the tensile strength of blank reach 85% ~ 95% of tensile strength by the amount of deformation and strain rate controlling blank, obtains a blank
S2: width adjustment, by rolling on edge by the width control system of a blank in the width range of transverse section;
S3: secondary tension adjusts, and is rolled time blank of after width adjustment, makes the tensile strength of a blank as far as possible close to tensile strength by the amount of deformation controlling blank, obtains secondary blank;
S4: thickness adjustment, is rolled secondary blank, makes the thickness size of secondary blank close to 90% of cross sectional thickness by controlling distortion amount;
S5: secondary width adjustment, carries out rolling on edge adjustment width in the width range of transverse section to the secondary blank after a thickness rolling;
S6: secondary thickness adjusts, and is rolled, makes the thickness of secondary blank become cross sectional thickness, obtain required wire rod by controlling distortion amount the blank after secondary width adjustment.
Also comprise the step to blank dephosphorization before described step S1, utilize shot-blasting machine to carry out dephosphorization to blank, by the iron scale except phosphorus ligands blank surface.、
The step that wire rod is detected also is comprised after stating step S6, carry out on tensile testing machine after wire rod is sampled, if detect the deviation range that the tensile strength obtained exceedes setting tensile strength, then the amount of deformation in set-up procedure S1 and strain rate make the wire rod finally obtained meet the demands.
The organic flexible pipe of high rigidity of band metal frame of the present invention and metal frame manufacture method utilize rolling to obtain the higher wire rod of tensile strength is curling becomes spiral skeleton, and the organic flexible pipe of the contrary skeletal support of two-layer Hand of spiral is set; The wire rod metal grain of rolling is tiny and even, tensility is much better than the circular section wire rod that cold-drawn goes out, the wire cross-section of rolling is rectangle, the sectional area same with circle can be obtained with thinner thickness, the stacked suit of multilayer skeleton can be realized when hose thickness is constant, finally improve the tensility of flexible pipe, be particularly suitable for using under tension requires higher occasion.
