Mold and Stranding Table for Layer Stranded Optical Cable Twisted Head Outlet Cover

Abstract

The invention discloses a layer-stranded cable winch outlet cover plate mould and a stranding platform. The layer-stranded cable winch outlet cover plate mould comprises a body. The body is provided with a reinforcing member through hole and a plurality of reaming holes distributed around the reinforcing member through hole. The distance between the reaming hole inlet end and the reinforcing member through hole is greater than the distance between the outlet end thereof and the reinforcing member through hole. According to the invention, by setting the reaming hole as an inclined hole, a sleeve is changed from the outlet end of the reaming hole into the inlet end thereof by a support point which changes direction; when the sleeve enters the reaming holes and moves forward along the axial direction of the reaming holes, the sleeve contacts the wall, which is close to the reinforcing member through hole, of the reaming holes; the contact area becomes larger; the interaction force betweenthe sleeve and a winch outlet cover plate is reduced, so that the wear period of the winch outlet cover plate is prolonged; the problem of tube difference caused by inconsistent resistance of the sleeve due to different degrees of wear of the winch outlet cover plate is avoided; and tension acting on the sleeve is stable and controllable.

Description

technical field [0001] The invention relates to the technical field of optical cable manufacturing equipment, in particular to a layer-twisted optical cable twist head exit cover mold and a twisting table. Background technique [0002] During the SZ stranding process of the layer-stranded optical cable, the sleeve needs to pass through the twisting table for stranding. When entering the paralleling mold, there is a clamp between the movement direction of the sleeve and the axial direction of the through hole on the stranding head for the strengthening member to pass through. Angle, while the reinforcing member passage hole on the cover plate of the twisting head outlet is coaxially arranged with the twisting head outlet. The process of casing from being parallel to the strengthening member to contacting and twisting with the strengthening member requires external force to change the progress of the casing. direction, and then carry out the stranding process.

Problems solved by technology

[0003] However, in the prior art, the reaming hole on the outlet cover plate of the twisting head is axially the same as the passing hole of the reinforcement member. Before the sleeve pipe comes out from the reaming hole and is twisted with the reinforcement member, the The tube always moves in the same direction as the reinforcement. When the sleeve comes out of the reaming hole and turns to contact the reinforcement, the contact point of the sleeve at the exit of the reaming hole provides this external force for changing direction, which makes the contact point There is not only the supporting force perpendicular to the advancing direction of the casing, but also the frictional force opposite to the advancing direction of the casing. The distance between the mold and the outlet cover of the twisting head is relatively short, and the casing is further rubbed and cut by the contact point at the exit of the twisting hole during the rotation process. The combined action of the above three forces causes the outlet of the exit cover of the twisting head to wear faster And the tension of the sleeve is unstable, and the difference in the degree of wear will be reflected in the length difference of the optical cable sleeve, which will affect the tensile performance of the optical cable and the overall stability of the product
