Description
Technical field
The utility model relates to fireproof electric wire and cable production field, particularly to a kind of milliken conductor stock block pinch roller mold base.
Background technology
Conductor manufacture is one of operation the most key in electric wire production process, there will be many problems in actual production.If conductor does not press, even if production process control below is good again or production equipment is advanced again, all cannot eliminate the adverse effect thus brought, conductor in batch even can be caused to scrap.Especially when manufacturing high voltage, electric cable with large cross-section conductor, the manufacture of its conductor is even more important.The reason that cause conductor compacting to go wrong, in addition to pressing mould, for milliken conductor, manufacture milliken conductor stock block and not only want Design of Dies accurate, be also the factor that can not ignore to the design of mold base structure.
Especially to high voltage electric cable with large cross-section, in order to reduce the impact of kelvin effect, stranding after a few personal share blocks of equalization need to be made, need to add insulating paper strip between stock block to separate, these multicore abnormity compact conductor stock blocks can make up a circle after extruded insulation, reducing the consumption of the external diameter of cable and associated materials, and reduce cable production cost.
When producing conductor, want to ensure the quality of conductor, in addition to mould itself, in addition it is also necessary to have convenient regulation mold base and mould with the use of.If mold base cannot conveniently regulate the position of mould, then even if Design of Dies standard again, also cannot produce the conductor meeting technological requirement.It because Design of Dies and process are inevitably present deviation, if mold base design is unreasonable, is difficult to operation, or mould can not be regulated to certain position, then cannot ensure that the size of conductor is accurate.More seriously, it is left-right asymmetry that the conductor produced there will be overlap, conductor, the large size conductor stranding not defects such as rounding, also can cause that insulation operation spark-over point is many, inner shield is caved in, and has a strong impact on the quality of cable.Additionally easily damage mould, cause die life to be substantially reduced.Therefore, by the improvement to abnormity compact conductor mold base, can reach that mould is easy for installation, the purpose of processing ease, and then can ensure that the quality of cable, improve production efficiency, reduce unnecessary loss.
At present, the mold base of the existing crosswise wire strander of China or frame type stranding machine assembles together again, is an entirety, cannot regulate online.If it is desired to regulation, it is necessary to disassemble and re-calibrate installation, operate and bother very much, and ratio is relatively time-consuming, have a strong impact on manufacturing schedule and product quality.The mold base part of wire twisting machine is as shown in Figure 1, including mould firm banking the 5th, mandrel the 4th, lining the 3rd, bearing the 2nd, stock block presses mould 1, in the fixing firm banking again of the bearing of this kind of structure, freely cannot come in and go out from the side opening on firm banking both sides, and bearing and press between mould, also a lining holds out against conductor compacting mould；The mold base of this structure, its bearing, lining and conductor compacting mould are fixed, cannot left and right adjusting, and when conductor compacting mould, lining and bearing machining there is deviation in its appearance and size, it assembles again together, there will be certain direction skew to the left and right in firm banking of conductor compacting mould, the conductor compacting mould in upper and lower firm banking cannot align；Conductor compacting mould is when the rotating clutch that aligns presses, and its gap is very little, even without gap, if do not alignd up and down, forces to rotate use, and the conductor produced is not only asymmetric, but also conductor can be caused to damage, and even also can cause burn failure.When particularly mould in use weares and teares bigger, pressing mould up and down and being more difficult to align, pressure production and application is easier to be occurred pressing burn failure and conductor quality problems.
Additionally, operation also inconvenience installed by mould, when conductor compacting mould and lining are together installed, conductor compacting mould, two linings are separate and movable relative to Qian type firm banking.Inside narrow and small Qian type firm banking, successively conductor compacting mould, two linings and two bearings are gone here and there together with one heart by shaft core, be relatively difficult.This will be wasted time and energy by slow with one's hands slow installation, reduces installation effectiveness, affects manufacturing schedule.Even if mould be arranged on mould seat frame fixing after, also cannot press the position of mould by on-line control, it is necessary to again disassembling and readjusting, time-consuming, efficiency is low.
To spend the time of a hour when mounted from the suitable pad of searching to Correction Die and formal production, such operating efficiency ratio is relatively low.Even if after fit on, when applying bigger pressure up and down, mould due to abrasion deviation, can cause the conductor pressing out defective in quality after producing a period of time.At this moment mould and mold base will be unloaded and re-calibrate device, it is impossible to on-line control, very inconvenient.If continuing production by force can cause the problems such as conductor is asymmetric, knife-like overlap, conductor damage.In order to avoid problem above, improving the cable conductor quality of production and production efficiency, conductor compacting mold base is carried out redesigning improvement by we.
Utility model content
