Abstract
The invention relates to a method for pressing a press pipe joint of a steel inhaul cable. The method comprises the following steps of: 1, heating the press pipe joint in rapid induction heating equipment at temperature of 950 DEG.C; 2, allowing the steel inhaul cable to pass through a cable hole in the middle of the press pipe joint; 3, putting the press pipe joint of the steel inhaul cable in a pressure module of a press machine, and pressurizing the press pipe joint of the steel inhaul cable and pressing; and 4, cooling the pressed press pipe joint of the steel inhaul cable, and cooling is to rapidly put the pressed press pipe in water. The method has the characteristics of highefficiency, low cost, simple process condition, and high quality of a workpiece.
Description
Technical field
The present invention relates to a kind of drawing method of pressure pipe joint, particularly relate to a kind of drawing method of steel cable pressure pipe joint.
Background technology
At present, the pressure pipe joint drag-line is the crucial primary structure member that is applied in bridge, building structure, curtain wall or other structure, as shown in Figure 1, its typical structure be pressure pipe joint 1 is that pressured pipe joint pressurized produces the anchor connection that forms the rope groove after flow at the pressure pipe joint inwall with being connected of cable body 2.
In the prior art, common drawing method has colds pressing and hot pressing, and harder during due to pressure pipe joint normal temperature when colding pressing, the resistance of deformation during compacting is larger, press rear resilience also larger, therefore colding pressing generally is only applicable to the drag-line pressure pipe joint compacting that some plasticity are good, intensity is low, specification is little.Hot pressing is that pressure pipe joint is heated to suppress after uniform temperature, then naturally cooling, this kind hot-press method has three shortcomings at least, and the one, heating-up temperature is improper, cause pressure pipe joint to be suppressed in the brittle zone of metal, easily crack in pressure pipe joint during compacting; The 2nd, to not restriction heat time heating time, cause some metal materials in the heating process of long-term heating, separating out of unfavorable tissue to be arranged, the 3rd, do not adopt not coolingly fast, cause continuing to separate out with inner wire and being heated for a long time of unfavorable tissue in cooling procedure, affect performance.
Summary of the invention
Technical problem to be solved by this invention is to provide the drawing method of the steel cable pressure pipe joint that a kind of efficient is high, cost is low, process conditions are simple, matter part quality is high.
The present invention solves the problems of the technologies described above by the following technical solutions:
A kind of drawing method of steel cable pressure pipe joint comprises:
Step 1: pressure pipe joint is put into quick induction heating equipment heat, heating-up temperature is not more than 2 minutes heat time heating time more than 950 ℃;
Step 2: steel cable is penetrated the Suo Kongzhong of the pressure pipe joint after heating, form the steel cable pressure pipe joint;
Step 3: described steel cable pressure pipe joint is put into the pressure mould of forcing press, described steel cable pressure pipe joint is suppressed;
Step 4: the described steel cable pressure pipe joint after suppressing is cooling, and cooling is that pressure pipe joint is put into water fast is cooling.
Further, described quick induction heating equipment is the medium-high frequency induction heating equipment.
Further, described medium-high frequency induction heating equipment comprises heater coil, and described heater coil is used for described pressure pipe joint is heated.
Temperature when further, described step 3 is suppressed is more than 950 ℃.
Further, described steel cable pressure pipe joint is two-phase stainless steel cable pressure pipe joint.
Compared with prior art, the invention has the beneficial effects as follows:
(1) adopt quick induction heating equipment in heating steps of the present invention, particularly adopt the heating of medium-high frequency load coil, heat time heating time is extremely short, avoids the generation of precipitated phase in heating process, and firing rate is fast, energy consumption is low;
(2) in heating steps of the present invention, heating-up temperature reaches more than 950 ℃, avoids suppressing joint in the brittle zone moulding;
(3) it is cooling fast that the present invention adopts water after pressing step, avoids separating out of the compacting harmful phase of joint of steel cable in the Slow cooling process; Simultaneously, cooling fast, avoid the steel cable steel wire to be subject to long-term baking and affect performance; The cooling dual-phase steel material that also makes is equivalent to do solution treatment fast, has guaranteed the anti-corrosion property of compacting joint.
Description of drawings
Fig. 1 is steel cable and pressure pipe joint syndeton schematic diagram in prior art;
Fig. 2 is the schematic diagram that pressure pipe joint of the present invention adopts the heating of medium-high frequency induction heating equipment;
Fig. 3 is the schematic diagram that pressure pipe joint of the present invention is suppressed by forcing press.
The specific embodiment
The present invention relates to a kind of drawing method of steel cable pressure pipe joint, below in conjunction with the drawings and specific embodiments, technical solution of the present invention is described.
The method step of steel cable pressure pipe joint compacting in the present embodiment is as follows:
Step 1: as shown in Figure 2, pressure pipe joint 10 is heated in the heater coil 31 of medium-high frequency induction heating equipment 30, heat time heating time within two minutes, the short generation that can avoid at the precipitated phase of pressure pipe joint described in heating process of the time of heating; Heating-up temperature reaches more than 950 ℃, and described heating-up temperature is avoided material in the brittle zone moulding.
Step 2: as shown in Figure 3, described steel cable 20 is penetrated the middle Suo Kongzhong of described pressure pipe joint 10, the pressure pipe joint 10 that will penetrate again steel cable 20 is placed in the pressure mould 41 of forcing press 40, starting pressure machine 40 makes two pressure mould 41 matched moulds in up and down carry out the compacting of pressure pipe joint 10, temperature during compacting is more than 950 ℃, is forced into after certain pressure separately pressure mould 41 of operating pressure machine 40; Described forcing press 40 is pressure pipe joint pressing pressure machine commonly used.
Step 3: after described steel cable pressure pipe joint suppresses, described steel cable pressure pipe joint is put into water fast cooling.Described cooling process has fast been avoided being harmful to separating out of phase in the cooling procedure, also avoids the drag-line steel wire be subject to long-term baking and affect performance.
Except the described steel cable pressure pipe joint of above-described embodiment can adopt two-phase stainless steel cable pressure pipe joint, in the cooling step process of the inventive method, the cooling dual phase steel that makes is equivalent to do solution treatment fast, has guaranteed the anti-corrosion property of pressure pipe joint.
The above-mentioned specific embodiment has been described in realization in order to demonstrate the invention.But other variations of the present invention and modification are apparent for those skilled in the art, and any modification in essence disclosed in this invention and basic principle scope/variation or imitation conversion all belong to claim protection domain of the present invention.
