The technical problem that the present invention also will solve is: a kind of expansion method that uses above-mentioned seamless dilator cold shrinking power cable adjunct to be carried out seamless expansion is provided, and the object of the invention realizes by following technical proposals:
A kind of seamless expansion method of cold shrinking power cable adjunct comprises the steps:
1. select and silicon rubber pressing mold and seamless dilatation mold that product mates;
Evenly coat lubricating grease 2. for product inwall and seamless dilatation mold outer surface;
3. the vertical hydraulic oil cylinder that starts seamless dilator is opened 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, the conical head and the mould pipe that promote mould with horizontal hydraulic jack advance, and product is expanded, until conical head is shifted silicon rubber pressing mold outside onto, need this moment the expansion product to expand fully on the mould pipe of dilatation mold;
5. the vertical hydraulic oil cylinder is motionless, pulls out the conical head of seamless dilatation mold, puts into the support bar that mates with product, and support bar exposes product 1-3cm;
6. the horizontal hydraulic pressure oil cylinder is drawn back, and pulls out the guide post of seamless dilatation mold, and at this moment product is enclosed within on the support bar fully, and the expansion product is complete.
1. mating with product described in the step, the internal diameter and the product that refer to the seamless dilatation mold selected finally equate through the external diameter that expansion need reach, the internal diameter of the mould pipe of the seamless dilatation mold of selecting and the external diameter that product augmentation need reach equate, the external diameter of the guide post of the seamless dilatation mold of selecting is less than the internal diameter of expansion product, and the through hole of the silicon rubber pressing mold of selection and the external diameter of product equate.
5. the support bar in the step expose product 3cm.
6. the set the purpose that support bar exposes product 1-3cm in the step is: make expansion finished product out no longer need to adjust, if support bar is shorter than finished product, the finished product contraction that can deform, if support bar is than long too many of finished product, the waste material, to extract support bar out when using simultaneously, bad location when oversize words are installed product.
Beneficial effect of the present invention: this dilator and expansion method are easy to use, and production efficiency is high, and the breakdown hidden danger of quality of product of having avoided traditional expansible method of steel wire expanding machine to cause has improved product quality.
