Description
Technical field
The present invention relates to continuous lead sheathing extruder field, more particularly to a kind of water conservancy diversion core rod.
Background technology
With World Economics and the fast development built, lead-sheathing cable is corrosion-resistant strong due to having the characteristics that, extensive
Applied to every field, such as submarine cable and deep-well oil field cable, demand also constantly increase.And to producing lead-sheathing cable
The demand of equipment also increasingly show.
Now in the art, continuous lead sheathing extruder is one of equipment for producing electric wire, and it is to be used for cable cladding lead that it, which is acted on,
Sheath.But during actually coating, it is usually present the problem of lead sheath can not be uniformly coated on electric wire.
In order to solve the above-mentioned technical problem, following scheme is proposed in the prior art：
Prior art if Chinese patent notification number is CN201673734U discloses a kind of connect on December 15th, 2010
Continuous lead extruder die holder, its technical scheme are that the mold holder of continuous lead extrusion machine includes water conservancy diversion core rod, core rod, die cap, are filled on die holder top
There is boom hoisting, boom hoisting afterbody is provided with suspension hook, and suspension hook is arranged in the chute of boom hoisting body.The advantages of patent
It is that lead layer wall thickness can be adjusted with adjusting device, preferable lead layer can be reached by the rotation of large and small handwheel.
And for example Chinese patent notification number is that CN204010846U prior art disclosed one kind on December 10th, 2014
New type of continuous lead extruder die holder, its technical scheme are that the new type of continuous lead extruder die holder includes core rod, adjusting screw rod, flow-guilding mold
Core, die cap and hydraulic pressure mould adjusting mechanism, the water conservancy diversion core rod include water conservancy diversion core rod body, are communicated with the water conservancy diversion core rod body
Lead liquid entrance and lead liquid manifold port, the lead liquid manifold port is connected with core rod, and the port of the lead liquid manifold port is ellipse
Circle.The patent overcomes the problem of large-diameter cable lead layer thickness deviation is larger, as long as user buys a lead extruder, two moulds
Seat, the electric wire with regard to that can produce Φ 20-Φ 140mm specifications, greatly reduces user's production cost, improves market competition
Power.But during actually coating, lead liquid is moved upwards along water conservancy diversion core rod, and the shadow with lead liquid gravity is limited by water conservancy diversion mold insert structure
Ring, the lead amount of water conservancy diversion core rod lead liquid entrance and the lead amount of water conservancy diversion core rod bottom are to be more than water conservancy diversion core rod lead liquid exit certainly
Lead amount and the lead amount on water conservancy diversion core rod top, this necessarily causes the cladding of lead sheath uneven.Ought particularly need coat Φ 100-
The lead liquid needed during the large-diameter electric wire cable of Φ 200mm specifications, during cladding is more, and the gravity of lead liquid is also very big, that is, is coating
During large-diameter electric wire cable, the problem of cladding is uneven has been further exacerbated by.In addition, though it is above-mentioned propose in the prior art it is logical
The technical scheme of adjusting device adjustment lead layer wall thickness is crossed, but the technical scheme can not equally make lead liquid be uniformly coated on electric wire electricity
On cable.
The content of the invention
It is an object of the invention to solve the above-mentioned problems in the prior art, there is provided a kind of water conservancy diversion core rod, the present invention
To lead liquid second diffluence and four split channels can be formed, so that lead liquid is uniformly coated on electric wire.
To achieve the above object, the technical solution adopted by the present invention is as follows：
A kind of water conservancy diversion core rod, it is characterised in that：Including core rod body, the end set of the core rod body has four lead liquid
Manifold port, is provided with conducting element, a position of splitter and two second diffluence parts on the core rod body, a position of splitter and
Conducting element is separately positioned on the both sides of core rod body, and two second diffluence parts are symmetricly set on core rod body, two secondary point
Stream part forms four second diffluence passages by a position of splitter and conducting element on core rod body.
Four described second diffluence passages enter the width all same at lead end.
The height all same of the conducting element, a position of splitter and two second diffluence parts on core rod body, and water conservancy diversion
Part, a position of splitter and two second diffluence parts are corresponding with four lead liquid manifold ports respectively.
The cross section of the second diffluence part is triangular structure, and three equal roundings in angle on second diffluence part are set
Put.
Rounding radii of the second diffluence part bottom close to the angle of conducting element is 55-65mm, the second diffluence part
Rounding radii of the bottom close to the angle of a position of splitter is 8-12mm, the rounding radii of drift angle on the second diffluence part
For 10-20mm.
Using the advantage of the invention is that：
First, in the present invention, two can be formed on core rod body and is once shunted with conducting element by a position of splitter and is led to
Road, by the cooperation of two second diffluence parts and conducting element and a position of splitter, can be formed on core rod body four it is secondary
Split channel, four second diffluence passages can will enter the lead liquid uniform divided flows of core rod body, meanwhile, two second diffluence parts are also
Lead liquid in second diffluence passage can be supported, core rod body is easily deposited in because being affected by gravity to solve lead liquid
The problem of bottom.In addition, by the cooperation of four second diffluence passages and four lead liquid manifold ports, with regard to lead liquid can be made from four lead
Liquid manifold port equably flows out, so that lead liquid is uniformly coated on electric wire.Compared with prior art, the present invention only exists
Two second diffluence parts and two lead liquid manifold ports are added on existing water conservancy diversion core rod, it becomes possible to reach uniform covered electric cable electricity
The purpose of cable, especially suitable for coat Φ 100-Φ 200mm specifications large-diameter electric wire cable, while also have it is simple in construction,
The advantages of cost is cheap and covered effect is good.
2nd, in the present invention, four second diffluence passages enter the width all same at lead end, and the structure causes secondary into four
The lead liquid measure of split channel is uniform, is advantageous to the uniformity of further lifting lead sheath cladding.
3rd, in the present invention, the height of conducting element, a position of splitter and two second diffluence parts on core rod body is homogeneous
Together, and conducting element, a position of splitter and two second diffluence parts are corresponding with four lead liquid manifold ports respectively, and the structure causes four
Lead liquid energy in bar second diffluence passage enough equably flows out from lead liquid manifold port.
4th, in the present invention, the cross section of second diffluence part is triangular structure, and three angles on second diffluence part are fallen
Fillet is set, and the structure can avoid that lead liquid is caused to stop so that lead liquid energy more swimmingly flows in second diffluence passage
It is dynamic.
5th, in the present invention, rounding radii of the second diffluence part bottom close to the angle of conducting element is 55-65mm, secondary point
It is 8-12mm to flow rounding radii of the part bottom close to the angle of a position of splitter, the rounding radii of drift angle on second diffluence part
For 10-20mm, using so specific rounding radii lead liquid can be made more swimmingly to be flowed in second diffluence passage.
