Abstract
The utility model discloses a mark-free expansion die for cold-shrinkable cable fittings, which comprises a die tube and a tapered head clamped at the larger open end of the die tube, wherein the maximum end of the tapered head is equal to the outside diameter of the die tube, a horizontal guide rod is connected to the tapered head, the inside diameter of the die tube is equal to the outside diameter required for expanding a product, and the outside diameter of the guide rod is less than the inside diameter of the product. The mark-free expansion die for cold-shrinkable cable fittings is convenient to use, has high production efficiency, prevents abrasions of both the die and the product, avoids the quality problem of product breakdown caused by the conventional steel wire expander die, and improves the quality of products.
Description
Technical field
The utility model relates to a kind of seamless dilatation mold of cold shrinking power cable adjunct.
Background technology
Steel wire dilator mould is adopted in the expansion of existing cold shrinking power cable adjunct; the material of its tapered head and mould pipe is all nylon; case hardness is low; and steel wire is the frequent mould that can wear and tear that slides on its surface; also can scratch the product inwall after mould is impaired, the most serious problem is that product of every expansion will be extracted 16 steel wires, and the product inwall has 16 sulculuses like this; any one sulculus all might cause product to puncture, and increases the hidden danger that product quality accident takes place.
The utility model content
The technical problems to be solved in the utility model is at above-mentioned situation, a kind of can not wear and tear mould and product is provided, avoids the dilatation mold of the breakdown cold shrinking power cable adjunct of product.
The purpose of this utility model realizes by following technical proposals:
The seamless dilatation mold of a kind of cold shrinking power cable adjunct, comprise the mould pipe, be connected to the mould pipe conical head of openend greatly, the maximum end of described conical head equals the external diameter of mould pipe, on described conical head, be connected with the guide post of one section level, the external diameter that the internal diameter of described mould pipe and product augmentation need reach equates that the external diameter of described guide post is less than the internal diameter of expansion product.
As optimal way, the tapering of conical head is between 12 °-20 °.
As optimal way, described conical head is the stainless steel conical head.
As optimal way, described mould pipe is stainless punching block pipe.
As optimal way, the external diameter of described guide post is than the little 1-3mm of internal diameter of expansion product.
As optimal way, described mould pipe is provided with the threaded ends that is threaded with dilator away from an end of conical head.
Using method of the present utility model is: 1, the silicon rubber mould and the seamless dilatation mold of selection and product coupling, the external diameter that the internal diameter of seamless dilatation mold and product augmentation need reach should equate.2, evenly coat lubricating grease for product inwall and seamless dilatation mold outer surface, 3, start the vertical hydraulic oil cylinder of seamless dilator, open the silicon rubber pressing mold, product is placed in the through hole at silicon rubber center, product to be expanded is through on the guide post of seamless dilatation mold, and closes tight silicon rubber pressing mold.4, start the horizontal hydraulic pressure oil cylinder of seamless dilator, the conical head and the mould pipe that promote mould with horizontal hydraulic jack advance, product is expanded, shifted onto silicon rubber pressing mold outside, need this moment the expansion product to expand fully on the mould pipe of dilatation mold up to conical head.5, the vertical hydraulic oil cylinder of seamless dilator is motionless, pulls out the conical head of seamless dilatation mold, puts into the support bar with the product coupling, 6, the horizontal hydraulic pressure oil cylinder of seamless dilator is drawn back, pull out the guide post of seamless dilatation mold, at this moment product is enclosed within on the support bar fully, and the expansion product finishes.
The beneficial effects of the utility model are: the utility model is easy to use, the production efficiency height, and mould and product can not wear and tear, and the breakdown hidden danger of quality of product of having avoided traditional steel wire dilator mould to cause has improved product quality.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, 1 is conical head, and 2 is the mould pipe, and 3 is guide post, and 4 is threaded ends.
The specific embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
As shown in the figure, the seamless dilatation mold of a kind of cold shrinking power cable adjunct, comprise mould pipe 2, be connected to the conical head 1 of the big openend of mould pipe, the maximum end of described conical head 1 equals the external diameter of mould pipe 2, on described conical head 1, be connected with the guide post 3 of one section level, the external diameter that the internal diameter of described mould pipe 2 and product augmentation need reach equates, the external diameter of described guide post 3 is than the little 1-3mm of internal diameter of expansion product, the tapering of conical head is between 12 °-20 °, described conical head 1 is the stainless steel conical head, described mould pipe 2 is stainless punching block pipe, and described mould pipe is provided with the threaded ends 4 that is threaded with dilator away from an end of conical head.
Using method of the present utility model is: 1, the silicon rubber mould and the seamless dilatation mold of selection and product coupling, the external diameter that the internal diameter of seamless dilatation mold and product augmentation need reach should equate.2, evenly coat lubricating grease for product inwall and seamless dilatation mold outer surface, 3, start the vertical hydraulic oil cylinder of seamless dilator, open the silicon rubber pressing mold, product is placed in the through hole at silicon rubber center, product to be expanded is through on the guide post 3 of seamless dilatation mold, and closes tight silicon rubber pressing mold.4, start the horizontal hydraulic pressure oil cylinder of seamless dilator, the conical head 1 and the mould pipe 2 that promote mould with horizontal hydraulic jack advance, product is expanded, shifted onto silicon rubber pressing mold outside, need this moment the expansion product to expand fully on the mould pipe 2 of dilatation mold up to conical head.5, the vertical hydraulic oil cylinder of seamless dilator is motionless, pulls out the conical head of seamless dilatation mold, puts into the support bar with the product coupling, 6, the horizontal hydraulic pressure oil cylinder of seamless dilator is drawn back, pull out the guide post of seamless dilatation mold, at this moment product is enclosed within on the support bar fully, and the expansion product finishes.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
