Abstract
A kind of cable cover(ing) is extruded with vaccum-pumping equipment, and its special character is: be made up of tube connector, control wind body, guide duct and peripheral pump; Be provided with screw thread in the inside, one end of described tube connector, described control wind body is inserted into the other end of described tube connector, and the centre of described tube connector is provided with connector, and connector is connected with one end of guide duct, and the other end of guide duct is connected with peripheral pump; Described control wind body, comprise two and fasten rear stepped cylindrical half cylinder, the center of described control wind body is provided with horn mouth, is positioned at outside horn mouth is along the circumferential direction uniformly distributed multiple ventilation hole at control wind body.Beneficial effect is: sheath can be made when extruding, the air between sheath and armour to be taken away, makes to combine closely between sheath and armour, avoids sheath at the succeeding stretch at armour band place; Combine with armour rapidly after sheathing, the extruded velocity of cable cover(ing) can be accelerated, enhance productivity.
Description
Technical field
The utility model relates to a kind of cable cover(ing) and extrudes and use vaccum-pumping equipment.
Background technology
Power cable especially high voltage electric cable with large cross-section occupies very important effect in transmission of electricity, and cable product quality decides its useful life, is the important foundation of electrical network normal power supply.Electric cable with large cross-section generally has double armor structure, and the larger armour in cross section is thicker, and two-layer armour difference in height is more obvious, and cause easily producing space between sheath and nexine armour, when extruding, restrictive coating is easily loose.Easily produce succeeding stretch at outer steel band edge place when sheath is loose, succeeding stretch causes sheath drawing point thinning, affects the quality of sheath.
Summary of the invention
The purpose of this utility model to solve the problems referred to above that prior art exists, and provides a kind of when cable cover(ing) is produced, more tight between sheath and steel band, and the cable cover(ing) being not easy generation succeeding stretch is extruded and used vaccum-pumping equipment.
Technical solution of the present utility model is:
Cable cover(ing) is extruded with vaccum-pumping equipment, and its special character is: be made up of tube connector, control wind body, guide duct and peripheral pump;
Screw thread is provided with in the inside, one end of described tube connector, described control wind body is inserted into the other end of described tube connector, the centre of described tube connector is provided with connector, and tube connector is connected with one end of guide duct by connector, and the other end of guide duct is connected with peripheral pump;
Described control wind body, comprise two and fasten rear stepped cylindrical half cylinder, the small diameter part position of described control wind body is inserted in described tube connector, and the center of described control wind body is provided with horn mouth, is positioned at outside horn mouth is along the circumferential direction uniformly distributed multiple ventilation hole at control wind body.
The beneficial effects of the utility model are:
1, this cable cover(ing) is extruded vaccum-pumping equipment sheath can be made when extruding, the air between sheath and armour to be taken away, makes to combine closely between sheath and armour, avoids sheath at the succeeding stretch at armour band place.
2, combine with armour rapidly after sheathing, the extruded velocity of cable cover(ing) can be accelerated, enhance productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-tube connector, 2-controls wind body, 3-guide duct, 4-peripheral pump, 5-screw thread, 6-connector, 7-hollow round table, 8-ventilation hole, 9 cables.
Embodiment
As shown in the figure, a kind of cable cover(ing) that the utility model relates to is extruded with vaccum-pumping equipment, is made up of tube connector 1, control wind body 2, guide duct 3 and peripheral pump 4.
Described tube connector 1 is made up of steel pipe, screw thread 5 is provided with in the inside, one end of described tube connector 1, described control wind body 2 is inserted into the other end of described tube connector 1, the centre of described tube connector 1 is provided with connector 6, tube connector 1 is connected by connector 6 one end with guide duct 3, and the other end of guide duct is connected with peripheral pump 4.
Described control wind body 2, comprise two and fasten rear stepped cylindrical steel half cylinder, the small diameter part position of described control wind body 2 is inserted in described tube connector 1, and the center of described control wind body 2 is provided with horn mouth 7, for guiding and the walking of cable.Be positioned at outside horn mouth 7 at control wind body 2 and be along the circumferential direction uniformly distributed multiple ventilation hole 8.
During installation, tube connector 1 is connected with cable 9 by screw thread 5, and cable 9 inserts tube connector 1 by the horn mouth 7 of control wind body 2 and is connected with the head of extruder after tube connector 1 passes.
In cable extrusion, utilizing stopper to block ventilation hole, by regulating opening and closedown of ventilation hole, regulating the size of air quantity within the specific limits, and then the negative pressure value in adjustment tube connector, make to combine closely between sheath and armour.
