Description
Technical field
The utility model belongs to the cable manufacturing technology, specifically is a kind of metal compound belt armouring plug die cooling device.
Background technology
Along with the fast development of global information communication letter industry, the construction dynamics of the communications infrastructure is also strengthening.Equipment to cable products also requires to develop towards the direction of high production speed, high technology performance.The metal compound belt armouring of line cable industry can provide mechanical protection to cable products, prolongs cable useful life, is the requisite measure that guarantees communication line transmission performance long-term effectiveness.So most of cable products has adopted the vertical composite band production technology (metal tape flanging → pre-vertical bag → vertical wrap molding → compression sizing) that belongs to covered with gold leaf, has adopted vertical packet technology can improve the production linear speed greatly simultaneously.
In the vertical job contract skill of metal tape, external diameter difference behind the vertical wrap molding of common metal band and the compression sizing has 0.5mm, 0.5mm the external diameter difference need plug die to compress, there are friction, resistance in the plug die compression process, in order to ensure the stable application in high-speed production of vertical packet technology, adopt following measure usually:
1. vertical bag adopts pair thick polyethylene films of surface-coated 0.05mm to improve the tensile strength of metal tape with the metal compound belt overwhelming majority, and the coefficient of reducing friction reduces the cohesive force between broken belt and enhancing and sheath in process of production;
2. wear and tear in long-term high-speed cruising in order to reduce plug die and metal tape, generally all adopt metal die.But metal die can generate heat in the long-play friction, the temperature of friction can reach nearly 100 ℃, this temperature makes the metal compound belt coated film be subjected to thermal softening, but it is to be provided by film that the precoated metal band has 40% stretching resistance value approximately, when film is subjected to thermal softening, the coefficient of friction of metal composite belt surface increases and the stretching resistance of band descends greatly, and (or without metal plug die) increased nearly more than 30% when the broken belt incidence was than low speed in process of production.
At the phenomenon that disconnected cable takes place frequently, can take following countermeasure:
1. adopting not can be because of the sizing mould of frictional heating---and this sizing mould need be selected hard material easily processing again for use, preferably the selection of material is laminated rod (bakelite), but its material is not wear-resisting, just must change behind the basic production 50km product, sizing mould internal diameter can make the vertical internal diameter that belongs to composite band covered with gold leaf become big in wear process, as rising significantly to optical cable infiltration disqualification rate, the price of laminated rod is also higher simultaneously, use is also very big to the pressure of cost in batches, and this is not completely safe plan!
2. metal die its temperature in the high-speed production process that sizing is used does not rise---preferably the heat of its generation taken away, practical, the most effective carrier is water or air at present, but cable products in vertical packet procedures the most I guess water and for seal request height, the execute-in-place complexity of water circle device, how to guarantee stable water source and more serious etc. the problem that exists of abnormal conditions consequence occurs.
The utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome the prior art solution to make a decision defectives such as the used sizing mould of cable phenomenon is not wear-resisting, cost height, and a kind of metal compound belt armouring plug die cooling device is provided.
For achieving the above object, metal compound belt armouring plug die cooling device of the present utility model, it is characterized in that: constitute a ring seal space by a sizing die sleeve and a die sleeve seat, described ring seal space is provided with input pore, output pore, and the assembling through hole for the assembling plug die is made at the center of described sizing die sleeve.
As the optimization technique means, described plug die cover has the hole wall that surrounds described assembling through hole and from the outside outer flanging of bending of an end of described hole wall; Described die sleeve seat have an end face and from the periphery of described end face to the axially extended ring wall of described end face one side, described end face is provided with through hole; Through hole on the corresponding described die sleeve seat end face of the assembling through hole of described sizing die sleeve, the end face welding of the hole wall of described sizing die sleeve and described die sleeve seat, the outer flanging of described sizing die sleeve and the welding of the ring wall of described die sleeve seat, described hole wall, outer flanging, end face, ring wall surround described ring seal space.
As the optimization technique means, described input pore, output pore are from axially or circumferentially being communicated with described ring seal space.
As the optimization technique means, described input pore, the distribution that is centrosymmetric of output pore.
The beneficial effects of the utility model are: the utility model constitutes a ring seal space by a sizing die sleeve and a die sleeve seat, and the ring seal space is provided with input pore, output pore, adopts the type of cooling of air circulation to realize cooling; Compressed air uses, gets source side just; Device is simple, and is easy to operate; Go out abnormal conditions and handle conveniently, can ignore the consequence that causes; Existing processes, work flow and buying etc. are not all exerted an influence; Drop into little, simple, control is convenient and effect is obvious etc., is conducive to improve product quality, advantage such as enhance productivity.
