Description
Technical field
The utility model belongs to electric wire manufacturing technology field, is specifically related to a kind of extrusion die relieving attachment for electric wire lopping technology of the package.
Background technology
At wires and cables industry, the cable product specification is numerous.Wherein, when producing plastic material cotton covered wire series products, last one production process is the lopping packaging process, this process flow is: one whole section cotton covered wire of the 3-5km that will take turns around 630 frocks is divided into per 100 meters one section by looping device, will cut apart afterwards 100 meters one section good cotton covered wire according to certain rear sale of outside dimension arrangement lopping packing.Because the cotton covered wire series products is mainly used in room lighting, thereby the output of annual China cotton covered wire series products is all very large, the per 100 meters lopping of the product General Requirements of the cotton covered wire class of producing, the quantity of the lopping cotton covered wire of producing is very large.Although the quantity of lopping cotton covered wire is very large, but the electric wire for same cross section different model, all different with oversheath thickness because of the insulating barrier that cable has, insulating barrier and the oversheath operation of therefore producing different electric wires just need to use the extrusion die of different size.
In the actual cable production process, squeeze replaceable at most 20 cover extrusion dies in the insulation operation.As shown in Figure 1, described extrusion die comprises core rod 9 and die sleeve 10, after extrusion die is finished using, need extrusion die is disassembled from head, in order in time core rod 9 and die sleeve 10 are separated, but this moment the extruder die temperature under the head dismounting up to 1500 ° about, be full of the plastics of molten state in the die cavity between core rod 9 and the die sleeve 10, if will separate core rod 9 and die sleeve 10 this moment, normally adopt the flat mouth bottle opener that the interface 6 of core rod and die sleeve is pried open, because the plastics of molten state are arranged in the die cavity of core rod and die sleeve, and the plastics of described molten state and mold temperature are all higher, so employing flat mouth bottle opener dismantles core rod as the extracting tool of extrusion die and there is following shortcoming in die sleeve:
1, because interface 6 gaps that core rod is connected with die sleeve is less, the gap is generally 0.06mm, therefore the flat mouth bottle opener will be inserted the interface 6 of core rod and die sleeve, and pry open the interface 6 of core rod and die sleeve very difficult, comparatively time-consuming, the time that spends needs about 20 minutes usually; And owing to be full of the plastics of molten state in the die cavity between core rod and the die sleeve, adopt the flat mouth bottle opener core rod and die sleeve are prized from process in, if other positions of staff or human body are not intended to touch core rod and the die sleeve of high temperature, the scald accident occurs easily, thereby bring hidden danger;
2, owing to frequent use interface 6 that the flat mouth bottle opener inserts core rod and die sleeve so that core rod and die sleeve are separated, get off for a long time, the surface of the interface of core rod and die sleeve will occur uneven, thereby make the appearance of core rod and die sleeve in conjunction with the phenomenon of rear decentraction, when producing electric wire, will produce the core shift phenomenon, the product quality of utilizing this core rod and die sleeve to produce can be affected, can't guarantee product quality, even can make product the serious glue phenomenon of leaking occur, can't start production equipment thereby cause, production is had a negative impact;
3, owing to frequently use mould in producing, so accelerated the rate of decay of mould, shortened its useful life, mould damages and just scraps and need to change, often one day frequent mould more than 20 overlaps when producing the busy season, more the mold exchange time cumulation is 4 hours, has not only increased production cost, and causes high percent defective and seriously reduced production efficiency.
