Description

Wrapping die

Technical Field

The utility model relates to a wrap mould is used for wrapping the cable in the cable course of working around the package processing.

Background

In the process of lapping and processing the cable, the lapping of the metal belt is a process of rotating at a high speed by taking the cable as a center in a suspended state. When the metal belt is wrapped, the center of the cable to be wound in the metal belt wrapping process must be ensured to be within a certain range. However, in the process of cable wrapping, a metal belt can generate a large centripetal force during wrapping, the metal belt wrapping on two sides is an inner-layer and outer-layer relation, the outer metal belt wraps the inner metal belt, the wrapping radiuses of the two metal belts are different, a centripetal force difference is formed, the cable to be wound is separated from the center, and the cable wrapping cannot meet the technical requirements.

The patent about strap cable is around package mould is mostly the steady line mould that controls unwrapping wire tension and reduce the cable and rock, obtains the relatively stable technological requirement of wrapping, needs in use, according to the cable at can bearing the stretching resistance within a definite time adjust unwrapping wire tension, the cable is unsettled between the steady line mould of inlet wire and the steady line mould of outlet wire and is wrapped the processing. The function of accurately controlling the stability of the lapping pitch of the metal belt is not provided. At the same time, there is a certain negative impact on the electrical and mechanical properties of the cable.

At present, the length of a cable to be wound in a metal tape wrapping area is controlled by increasing the lengths of a wire inlet die and a wire outlet die, so that the position of the cable to be wound, which is separated from the center, is controlled within a certain range, and the cable wrapping meets the technical requirements. However, with the use of the metal belt, the reduction of the metal belt can cause the weight of the metal belts on both sides to be inconsistent, which leads to the fact that the cable to be wound is separated from the center position more and more far in the wrapping process, and the cable to be wound is separated from the center position to a certain degree, which can cause the unstable and small wrapping pitch of the metal belt, the quality problems of edge warping, bag leakage and the like, and the continuous shutdown adjustment of an operator is needed.

The product which meets the technical requirements of cable lapping is achieved by increasing the paying-off tension; however, the metal belt wrapping process is still carried out in a suspended state, and the cable to be wound still has the problem of being separated from the center. What be different is through increaseing unwrapping wire tension to reduce the volume that waits to wind the cable and break away from central point to put, makes it produce the product that satisfies cable metal tape and wrap technical requirement. However, increased operating personnel's the operation degree of difficulty, all had high requirement to equipment and operating personnel, unwrapping wire tension increases the dynamics not enough, does not play a role, and unwrapping wire tension dynamics is too big, can cause some quality problems such as cable breaking or thin cable of drawing.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a can improve around package pitch stability, production efficiency around package mould.

In order to achieve the technical purpose, the wrapping mold of the present invention comprises a first half mold and a second half mold, wherein the first half mold (such as a half cylinder structure, the same below) and the second half mold form a half-wave structure (i.e. split half and half to form a mold together), a circular cable running channel is arranged between the first half mold and the second half mold, the cable running channel is composed of an inlet section and an outlet section, and the diameter of the outlet section is larger than that of the inlet section; and one or two tape inlet ports are formed in the front end of the outlet section and on the die.

Specifically, the number of the tape inlet ports is two, and the two tape inlet ports are symmetrically arranged along the cable walking channel.

As a preferred structure, the tape inlet of the wrapping tape is positioned at the contact surface of the first half die and the second half die; at the contact surface of a first half die and a second half die, one side of the first half die is provided with a first belt inlet groove, the other side of the first half die is provided with a second belt inlet groove, one side of the second half die is provided with a third belt inlet groove, and the other side of the second half die is provided with a fourth belt inlet groove; the first belt inlet groove, the third belt inlet groove, the second belt inlet groove and the fourth belt inlet groove respectively form a belt inlet of the wrapping belt.

Place the strap in around package course of working the utility model discloses an inside completion of mould, the metal band advances the area mouth along the mould and gets into the mould along circle (cable walking passageway) tangential direction in the mould, and mould and strap synchronous revolution utilize circle longitudinal fixation to wind package cable metal band position in the mould. The cable has been restricted the position by vertical lapping strap, and normal lapping can not be influenced to tension and centripetal force in the process of lapping, the fine above problem of having solved.

The diameters of the inlet section and the outlet section are calculated according to the outer diameter of the cable to be processed. The cable is limited to the central position of the mould, and the cable cannot be separated from the central position due to centripetal force in the metal tape wrapping process. Meanwhile, the paying-off tension is not increased, the cable to be wound cannot be separated from the central position due to centripetal force, and the phenomenon that the weight of two sides is inconsistent due to the fact that the metal belt is used and reduced can be avoided, so that the cable to be wound is separated from the central position more and more far in the wrapping process. The technical process pitch stability in the metal tape lapping process and the requirements of the electrical performance and the mechanical performance of the cable are met.

The metal belt wrapping processing process is placed in the die of the utility model, so that the precision and the production efficiency of the stability of the metal belt wrapping pitch are improved, and the quality problems of the electrical performance and the mechanical performance of the cable caused by the paying-off tension are avoided; the operation is simple and convenient, the requirements on the armor operation experience are low, and the product quality stability is ensured; the repair rate and rejection rate of the product caused by insufficient machining precision are reduced, and the product quality is ensured.
