Description
Technical field
The present invention relates to continuous lead sheathing extruder field, particularly relate to a kind of water conservancy diversion core rod.
Background technology
Along with World Economics and the fast development of construction, lead-sheathing cable is owing to having the corrosion-resistant feature such as by force, by extensively
Being applied to every field, such as submarine cable and deep-well oil field cable etc., demand the most constantly increases.And to producing lead-sheathing cable
The demand of equipment the most day by day manifest.
The most in the art, continuous lead sheathing extruder is one of equipment producing electric wire, and its effect is to be coated with lead for cable
Sheath.But during reality is coated with, it is usually present the problem that lead sheath can not be uniformly coated on electric wire.
In order to solve above-mentioned technical problem, prior art proposes following scheme:
Prior art if Chinese patent notification number is CN201673734U discloses a kind of the most crowded on the 15th at December in 2010
Lead machine die holder, its technical scheme is that this mold holder of continuous lead extrusion machine includes water conservancy diversion core rod, core rod, die cap, on die holder top equipped with rising
Device for hoisting, boom hoisting afterbody is provided with suspension hook, and suspension hook is arranged in the chute of boom hoisting body.The advantage of this patent is
Lead layer wall thickness can be adjusted with adjusting device, be rotated by large and small handwheel and can reach preferable lead layer.
And for example Chinese patent notification number is that the prior art of CN204010846U discloses one on 10th at December in 2014
New type of continuous lead extruder die holder, its technical scheme is that this 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, described water conservancy diversion core rod includes water conservancy diversion core rod body, described water conservancy diversion core rod body is communicated with
Lead liquid entrance and lead liquid manifold port, described lead liquid manifold port is connected with core rod, and the port of described lead liquid manifold port is ellipse
Circle.This patent overcomes the problem that large-diameter cable lead layer thickness deviation is bigger, as long as user buys a lead extruder, two moulds
Seat, just can produce the electric wire of Φ 20 Φ 140mm specification, greatly reduce user's production cost, improve the market competition
Power.But during reality is coated with, lead liquid moves upward along water conservancy diversion core rod, is limited and the shadow of lead liquid gravity by flow-guilding mold cored structure
Ringing, the lead amount of water conservancy diversion core rod Qian Ye import department and the lead amount of water conservancy diversion core rod bottom are certainly more than water conservancy diversion core rod lead liquid exit
Lead amount and the lead amount on water conservancy diversion core rod top, this necessarily causes the cladding of lead sheath uneven.Particularly it is coated with Φ 100 when needs
During the large-diameter electric wire cable of Φ 200mm specification, the lead liquid needed during cladding is more, and the gravity of lead liquid is the biggest, i.e. in cladding
During large-diameter electric wire cable, it is further exacerbated by the problem that cladding is uneven.Although it addition, above-mentioned prior art proposing logical
Cross adjusting device and adjust the technical scheme of lead layer wall thickness, but this technical scheme can not make lead liquid be uniformly coated on electric wire electricity equally
On cable.
Summary of the invention
It is an object of the invention to solve the above-mentioned problems in the prior art, it is provided that a kind of water conservancy diversion core rod, the present invention
Can be to lead liquid second diffluence and form four split channels, so that lead liquid is uniformly coated on electric wire.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of water conservancy diversion core rod, it is characterised in that: include that core rod body, the end of described core rod body are provided with four lead liquid and conflux
Mouthful, described core rod body is provided with conducting element, a position of splitter and two second diffluence parts, a described position of splitter and water conservancy diversion
Part is separately positioned on the both sides of core rod body, and two second diffluence parts are symmetricly set on core rod body, two second diffluence parts
On core rod body, four second diffluence passages are formed by a position of splitter and conducting element.
The width that four described second diffluence passages enter lead end is the most identical.
Described conducting element, a position of splitter are the most identical with two second diffluence parts height on core rod body, and water conservancy diversion
Part, a position of splitter are corresponding with four lead liquid manifold port respectively with two second diffluence parts.
The cross section of described second diffluence part is that three equal roundings in angle in triangular structure, and second diffluence part set
Put.
The described second diffluence part bottom rounding radii near the angle of conducting element is 55 65mm, described second diffluence part
The bottom rounding radii near the angle of a position of splitter is 8 12mm, the rounding radii of drift angle on described second diffluence part
It is 10 20mm.
Employing it is an advantage of the current invention that:
One, in the present invention, two split channels can be formed by a position of splitter on core rod body with conducting element, logical
Spend coordinating of two second diffluence parts and conducting element and a position of splitter, it is possible on core rod body, form four second diffluences lead to
Road, four second diffluence passages can will enter the lead liquid uniform divided flows of core rod body, and meanwhile, two second diffluence parts can also be right
Lead liquid in second diffluence passage is supported, and is easily deposited in core rod body lower part because being affected by gravity solving lead liquid
Problem.It addition, by four second diffluence passages and the cooperation of four lead liquid manifold port, lead liquid just can be made to conflux from four lead liquid
Mouth flows out, equably so that lead liquid is uniformly coated on electric wire.Compared with prior art, the present invention is only existing
Two second diffluence parts and two lead liquid manifold port are added, it becomes possible to reach the mesh of uniform covered electric cable cable on water conservancy diversion core rod
, it is particularly well-suited to be coated with the large-diameter electric wire cable of Φ 100 Φ 200mm specification, the most also there is simple in construction, low cost
The advantage that honest and clean and covered effect is good.
Two, in the present invention, the width that four second diffluence passages enter lead end is the most identical, and this structure makes to enter four secondaries
The lead liquid measure of split channel is uniform, is conducive to promoting further the uniformity of lead sheath cladding.
Three, in the present invention, conducting element, a position of splitter and two the second diffluence parts height on core rod body is homogeneous
With, and conducting element, a position of splitter are corresponding with four lead liquid manifold port respectively with two second diffluence parts, this structure makes four
Lead liquid in bar second diffluence passage can flow out from lead liquid manifold port equably.
Four, in the present invention, the cross section of second diffluence part is that three angles in triangular structure, and second diffluence part are all fallen
Fillet is arranged, and this structure is it can be avoided that cause stop to lead liquid so that lead liquid can flow in second diffluence passage more swimmingly
Dynamic.
Five, in the present invention, the second diffluence part bottom rounding radii near the angle of conducting element is 55 65mm, and secondary divides
The stream part bottom rounding radii near the angle of a position of splitter is 8 12mm, the rounding radii of drift angle on second diffluence part
It is 10 20mm, uses so specific rounding radii that lead liquid can be made to flow in second diffluence passage more swimmingly.
