Abstract
The utility model discloses a cable high temperature extruder with primary heater unit, which solves problem that when existing high temperature extruder produce soild wire with small section, bubble easy to be formed on completed product surface and cause industrial frequency grinding spark test failure. A wire primary heater unit is set before the cable high temperature extruder, and the wire primary heater unit is electric heating tube [2]. The utility model is capable of effectively solving bubble formed on completed product surface.
Description
Technical field
The utility model relates to a kind of cable high-temperature extrusion apparatus, especially a kind of cable high-temperature extrusion apparatus that has preheating device.
Background technology
The high temperature extrusion apparatus is a kind of visual plant in the cables manufacturing.Lead passes through the high temperature extrusion apparatus at lead outer wrapping plastic insulating layer, thereby becomes cable.But problem of ubiquity aborning, that is exactly when producing the single line of small bore, because of the matching problem of extrusion capacity and payingoff speed, at finished surface formation bubble, causes and can not pass through the power frequency sparking test easily.
The utility model content
The utility model solves above-mentioned high temperature extrusion apparatus exactly when producing the small bore single line, forms bubble at cable surface, and can not be by the problem of power frequency sparking test.
The technical solution adopted in the utility model is: the cable high-temperature plastic extruding machine of band preheating device, it is provided with the lead preheating device in the place ahead of cable high-temperature extrusion apparatus.
Adopt technique scheme,, dwindle itself and the temperature difference of extruding Insulation Material through the lead preheating device time, so cable surface can not form bubble because lead makes lead obtain certain temperature, thereby by the power frequency sparking test.
Above-mentioned lead preheating device is an electric heating tube.Heating by electric heating tube can reach the preheating to lead.
In sum, the beneficial effects of the utility model are: owing to before the high temperature extrusion apparatus, add preheating device, dwindle the lead and the temperature difference of extruding Insulation Material, so cable surface can not form bubble, thereby by the power frequency sparking test.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, 1, the high temperature extrusion apparatus, 2, electric heating tube, 3, lead, 4, cable.
Embodiment
The cable high-temperature plastic extruding machine of the utility model band preheating device, as shown in Figure 1, it is provided with the lead preheating device in the place ahead of cable high-temperature extrusion apparatus 1.Described lead preheating device is an electric heating tube 2.After carrying out preheating when lead 3 passes electric heating tube 2, by cost cable 4 behind the extrusion molding mouth of high temperature extrusion apparatus 1.
Claims (2)
1, the cable high-temperature plastic extruding machine of band preheating device is characterized in that it is provided with the lead preheating device in the place ahead of cable high-temperature extrusion apparatus [1].
