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; 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. The method has the characteristics of high efficiency, 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, 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 is a pressure pipe joint 1 and being connected of cable body 2 is that pressured pipe joint pressurized produces the anchor connection that forms the rope groove behind the flow in the pressure pipe inner nosepiece wall.
In the prior art, common drawing method has colds pressing and hot pressing, because harder during pressure pipe joint normal temperature, the resistance of deformation during compacting is bigger when colding pressing, press the back resilience also bigger, 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 to suppress after the pressure pipe joint is heated to uniform temperature, naturally cooling then, this kind hot-press method has three shortcomings at least, and the one, heating-up temperature is improper, cause the pressure pipe joint to be suppressed, easily crack in the pressure pipe joint during compacting in the brittle zone of metal; The 2nd, to heat time heating time without limits, 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 cooling fast, cause continuing to separate out and being heated for a long time of unfavorable tissue in the cooling procedure with inner wire, influence performance.
Summary of the invention
Technical problem to be solved by this invention is to provide the drawing method of a kind of efficient height, cost is low, process conditions are simple, matter part quality is high steel cable pressure pipe joint.
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: the pressure pipe joint is put into quick induction heating equipment heat;
Step 2: steel cable is penetrated the Suo Kongzhong of the pressure pipe joint after the heating, form 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 cooling after will suppressing.
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.
Further, be not more than 2 minutes the heat time heating time in the described step 1.
Further, the heating-up temperature in the described step 1 is more than 950 ℃.
Temperature when further, described step 3 is suppressed is more than 950 ℃.
Further, the cooling in the described step 4 is the pressure pipe joint to be put into water fast cool off.
Further, described steel cable pressure pipe joint is a 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 the 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 the heating process, and firing rate is fast, energy consumption is low;
(2) in the heating steps of the present invention, heating-up temperature reaches more than 950 ℃, avoids suppressing joint in the brittle zone moulding;
(3) the present invention adopts water to cool off fast behind pressing step, avoids separating out of the compacting harmful phase of joint of steel cable in the slow cooling procedure; Simultaneously, cooling fast avoids the steel cable steel wire to be subjected to toasting for a long time and influencing performance; Cooling also makes the dual phase steel material be equivalent to do solution treatment fast, has guaranteed the anti-corrosion property of compacting joint.
Description of drawings
Fig. 1 is steel cable and a pressure pipe joint connecting structure schematic diagram in the 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, technical solution of the present invention is described below in conjunction with the drawings and specific embodiments.
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, the time weak point of heating can be avoided the generation at the joint of pressure pipe described in heating process precipitated phase within two minutes; 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 Suo Kongzhong of described pressure pipe joint 10 centres, the pressure pipe joint 10 that will penetrate steel cable 20 more is placed in the pressure mould 41 of forcing press 40, starting pressure machine 40 makes that two pressure mould 41 matched moulds carry out the compacting of pressure pipe joint 10 up and down, temperature during compacting is more than 950 ℃, is forced into behind the 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 cool off.The process of described quick cooling has been avoided being harmful to separating out of phase in the cooling procedure, also avoids the drag-line steel wire to be subjected to toasting for a long time and influencing performance.
Remove the described steel cable pressure pipe of the foregoing description joint and can adopt two-phase stainless steel cable pressure pipe joint, in the cooling step process of the inventive method, cooling makes dual phase steel be 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 conspicuous for those skilled in the art, and any modification/variation in essence disclosed in this invention and basic principle scope or imitation conversion all belong to claim protection domain of the present invention.
