Abstract
The utility model relates to an insulation extrusion drawing wire pulling device for a radio frequency coaxial cable. The utility model is characterized in that a main drawing wheel, an auxiliary drawing wheel, and a connecting shaft, the main drawing wheel is connected at the upper end of the connecting shaft, an auxiliary pulley is connected at the lower end of the connecting shaft, the auxiliary pulley is connected with a main pulley through a driving belt, the main pulley is connected with a motor, and a slide rail is arranged on the bottom seat of the motor. The utility model has the advantages that the single stage belt driving is adopted to replace the gear driving, to make the superposition of the periodic defects not formed, and to make the voltage standing wave ratio of the cable not more than 1.15 in the using frequency range of the user; the structure is simple, the manufacture is easy, the qualified rate of the produced product is high.
Description
Technical field
The utility model relates to a kind of RF coaxial cable insulation cable and extrudes the unwrapping wire draw-gear
Background technology
At present, the unwrapping wire trailer system of domestic RF coaxial cable insulation cable production line is generally selected for use the higher and expensive reduction box of precision to be series at main drawing and is got between wheel and the motor, and its inside is the multi-stage gear transmission.Owing to be positive drive, gear whenever circles all can extrude cable insulation and produces small fluctuation, will cause cable excessive voltage standing wave ratio (VSWR) peak value to occur in pairing frequency range after this defective periodically superposes, and influences the serviceability of cable.Also can pass through formula in theory
Calculate this standing-wave ratio peak value.(f-standing-wave ratio minimum peak frequency MHz; T-defective period m; ε
DThe effective dielectric constant of-combined insulation)
Summary of the invention
The purpose of this utility model provides a kind of RF coaxial cable insulation cable and extrudes the unwrapping wire draw-gear, and it not only avoids using frequency range excessive voltage standing wave ratio (VSWR) to occur the user aborning effectively, and economical and practical, simple in structure, easy to manufacture.
The utility model is achieved like this, it comprise main draw get wheel, get wheel, coupling spindle, driving-belt, towing bracket, master tape driving wheel from drawing, from driven wheel, motor, slide rail.It is characterized in that, on towing bracket, connect main drawing to get wheel, get wheel and coupling spindle that the coupling spindle upper end connects the master and draws and get wheel from drawing, the lower end connects from driven wheel, connect the master tape driving wheel from driven wheel by driving-belt, the master tape driving wheel connects motor, and the base of motor is provided with slide rail.
The utility model has the advantages that: (1) adopts the transmission of single-stage driving band to substitute gear drive, makes its stack that can not form periodicity defect, makes the voltage standing wave ratio of cable use frequency range to be not more than 1.15 the user; (2) simple in structure, make easily the product percent of pass height of production.
Description of drawings
Fig. 1 is a structural representation of the present utility model; In the drawings, 1, main draw get wheel 2, get wheel 3, coupling spindle 4, driving-belt 5, towing bracket 6 from drawing, from driven wheel 7, master tape driving wheel 8, motor 9, slide rail
Embodiment
As shown in Figure 1, the utility model comprise main draw get wheel 1, get wheel 2, coupling spindle 3, driving-belt 4, towing bracket 5, master tape driving wheel 7 from drawing, from driven wheel 6, motor 8, slide rail 9.It is characterized in that, on towing bracket 5, connect main drawing to get wheel 1, get wheel 2 and coupling spindle 3 that coupling spindle 3 upper ends connect main drawing and get wheel 1 from drawing, the lower end connects from driven wheel 6, connect master tape driving wheel 7 from driven wheel 6 by driving-belt 4, the master tape driving wheel connects motor 8, and the base of motor is provided with slide rail 9.During start, motor rotates, and drives the rotation of master tape driving wheel, and the master tape driving wheel drives from driven wheel by driving-belt to be changeed, and main simultaneously drawing got the wheel rotation, and the trailing cable inner wire by regulating the bolt on the slide rail, can be adjusted the tensioning of driving-belt.Cable inner conductor was got wheel and is got wheel and be extruded into semi-finished product after around multi-turn from drawing through main drawing.
Claims (1)
