Description

A kind of seamless Through ground wire production technology of railway
Technical field
The invention belongs to the railway run-through ground line technical field in high-speed railway, seamless more particularly, to a kind of railway Through ground wire production technology.
Background technique
With the continuous enhancing of China's national power, the railway construction in China has obtained quick development.Wherein, Through ground wire is made For a part of safe railway operation, great role is played safely to railway operation.It is issued according to newest railway parent company CRCC provides detailed rules and regulations, and novel Through ground wire need to be seamless production, and railway run-through ground line product cut lengths Wei≤1000m, But it is produced currently, novel seamless Through ground wire mostly uses Large Diameter Pipeline threading to prick the mode of pulling out, this technology mode needs broad Production site and more people operation, manufacturing enterprise lesser for some places will be unable to realize production.
Summary of the invention
In view of this, the invention is intended to overcome above-mentioned defect existing in the prior art, propose that a kind of railway is seamless Through ground wire production technology.
In order to achieve the above objectives, the technical solution of the invention is achieved in that
A kind of seamless Through ground wire production technology of railway, includes the following steps:
1) copper strips is bent into section of jurisdiction;
2) each section of jurisdiction is justified surely;
3) section of jurisdiction after circle will be determined and is welded into copper pipe;
4) cable core is penetrated in above-mentioned copper pipe, and carries out drawing, rolling together with copper pipe;
5) annealing softening, cooling are successively carried out to the Through ground wire rolled;
6) after cleaning, dry above-mentioned Through ground wire, spray printing typewriting;
7) take-up.
Further, the copper strips in step 1) uses H60-H80 alloyed copper band.
Further, the caliber of copper pipe is 3 to 5 times of Through ground wire in step 3).
Further, it when step 4) rolls, is rolled using multiple tracks ligature wheel, weld seam is made to fade away.
Further, after step 5) anneals and is cooling, processing is passivated to Through ground wire.
Compared with the existing technology, the invention has the advantage that
Present invention process is simple, overcomes production site limitation, can produce to smooth lesser manufacturing enterprise, And railway run-through ground line Corrosion Protection produced and resistance to stress better performances, tensile strength and elongation at break are larger, electricity Resistance rate is lower, and product quality and service life has been effectively ensured.
Detailed description of the invention
The attached drawing for constituting a part of the invention is used to provide to further understand the invention, present invention wound The illustrative embodiments and their description made are used to explain the present invention creation, do not constitute the improper restriction to the invention.? In attached drawing:
Fig. 1 is the process flow chart of the invention.
Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the invention can To be combined with each other.
In the description of the invention, it is to be understood that term " center ", " longitudinal direction ", " transverse direction ", "upper", "lower", The orientation or positional relationship of the instructions such as "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" is It is based on the orientation or positional relationship shown in the drawings, is merely for convenience of description the invention and simplifies description, rather than indicate Or imply that signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore cannot understand For the limitation to the invention.In addition, term " first ", " second " etc. are used for description purposes only, and should not be understood as indicating Or it implies relative importance or implicitly indicates the quantity of indicated technical characteristic.In the description of the invention, unless It is otherwise noted, the meaning of " plurality " is two or more.
In the description of the invention, it should be noted that unless otherwise clearly defined and limited, term " peace Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally Connection;It can be mechanical connection, be also possible to be electrically connected;Can be directly connected, can also indirectly connected through an intermediary, It can be the connection inside two elements.For the ordinary skill in the art, on being understood by concrete condition State concrete meaning of the term in the invention.
Below with reference to embodiment come the present invention will be described in detail create.
A kind of seamless Through ground wire production technology of railway, as shown in Figure 1, including the following steps:
1) copper strips is bent into section of jurisdiction;
2) each section of jurisdiction is justified surely;
3) section of jurisdiction after circle will be determined and is welded into copper pipe;
4) cable core is penetrated in above-mentioned copper pipe, and successively carries out drawing, rolling together with copper pipe;
5) annealing softening, cooling are successively carried out to the Through ground wire rolled;
6) after cleaning, dry above-mentioned Through ground wire, spray printing typewriting;
7) take-up.
It should be noted that cable core drum can be filled on pay off rack, cable core is through over-discharge before putting band (or simultaneously) Line centering control device realizes that unwrapping wire, cable core successively after over-discharge tape holder and its guide wheel on top, enter copper pipe welding post,
It is of course also possible to be then to carry out unwrapping wire after the completion of copper pipe welding, cable core is formed directly into the metal tube after welding It is interior.
Wherein,
Copper strips in step 1) uses H60-H80 alloyed copper band.The oversheath of this seamless Through ground wire of railway uses H60-H80 copper alloy, H60-H80 copper alloy have the performance of stronger anticorrosive property and resistance to stress, it is ensured that railway run-through The quality of ground wire and service life, tensile strength and elongation at break are larger, and resistivity is lower, are not easy affected by force, Ke Yigeng Meet the use demand of railway run-through ground line well.
The caliber of copper pipe is 3 to 5 times of Through ground wire in step 3), and cable core is facilitated to penetrate, in rolling, and can be by cable Core is tightly coated in copper pipe (sheath).
When step 4) rolls, is rolled using multiple tracks ligature wheel, weld seam is made to fade away.Cable when rolling, in copper pipe Core can with copper alloy tube is asynchronous advances (due to the speed difference of Large Diameter Pipeline gradually contraction, so cable core is fast compared with copper pipe speed), Have no effect on product quality.
After step 5) annealing and cooling, processing is passivated to Through ground wire.
Above-mentioned technique is segmented progress in Through ground wire length range, greatly reduce place limitation, even place compared with Small manufacturing enterprise also can smoothly produce the Through ground wire of high quality.Specifically, step 1) is to 4) can be in Through ground wire Segmentation carries out in length range, can also carry out one section of one end in Through ground wire length range, pass through later by what rolling was completed Logical ground wire integrally annealed, cooling, then carry out last cleaning, drying and spray printing typewriting, all after the completion of, finished product is wound in cable On disk.
Present invention process is simple, overcomes production site limitation, can produce to smooth lesser manufacturing enterprise, And railway run-through ground line Corrosion Protection produced and resistance to stress better performances, tensile strength and elongation at break are larger, electricity Resistance rate is lower, and product quality and service life has been effectively ensured.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention Protection scope within.
