Abstract
The utility model discloses a high-frequency welded aluminum sheath diameter reducer, which comprises holders and diameter-reducing wheels; wherein, the horizontal holder is fixed on the main holder; the fixed diameter-reducing wheel is firmly connected with the horizontal holder; the sliding holder, on which the sliding diameter-reducing wheel is fixed, is connected with the horizontal holder by an adjusting bolt; the vertical holder which is fixed on the main holder is connected with the sliding holder by an adjusting bolt assembled on the vertical holder; the adjusting bolts can be adjusted in order to control the position of the sliding holder, so that the transverse and longitudinal extruding force of the sliding diameter-reducing wheel can be changed; an adjusting bolt which is used to change the transverse position of the sliding holder is assembled on the lateral side of the fixed extruding wheel; and an adjusting bolt which is used to change the longitudinal position of the sliding holder is assembled on the top of the vertical holder. The structure of the high-frequency welded aluminum sheath diameter reducer can prevent an aluminum tube from overturning, which is favorable for the extrusion of the aluminum tube. Meanwhile, the high-frequency welded aluminum sheath diameter reducer can eliminate the sharp corner or burrs of the welding line and reduce the gap between cable cores and the aluminum tube, so that the surface of the aluminum tube can become round, neat and smooth.
Description
Technical field
The utility model relates to electric wire manufacturing equipment field, particularly a kind of aluminium sheath tube reducing device that uses in making high-frequency welding aluminum-sheathed cable process.
Background technology
It is shielding and sealing gas that aluminium sheath plays a major role in cable, and sealing gas just requires can not defectiveness in certain-length.At present, the production equipment of aluminum-sheathed cable mainly contains: argon arc welding welding equipment, aluminium press extrusion equipment, continuously extruded coating equipment, ratio-frequency welding welding equipment.Wherein, first three kind aluminium sheath that equipment is produced, profile is rounding relatively, and cable core and aluminium sheath gap are little, but speed of production is slow, and generally in 15 meters/minute, so the general drawing shaping process that adopts utilizes PUR to serve as lubricant, shaping and gluing on-line synchronous are carried out.In addition, in the ratio-frequency welding production technology in early days, aluminum pipe is if any weld defect, be after utilizing the soldering method mending-leakage, again in the aluminum tube surfaces asphalt-coating as anticorrosive coat, therefore, require not tight to the shaped degree of aluminium sheath profile, even the aluminum pipe cross sectional shape can be oval, square, peach shape etc., and cable core and aluminium sheath internal diameter gap are also bigger, generally more than 2～3 millimeters.The main cause that produces this type of defective is to be: (1) because during ratio-frequency welding welding of aluminum sheath, aluminium strip is subjected to certain external compression power after becoming tubulose, and weld bond is to outer process, thus welding afterwards the disconnected cross sectional shape of aluminum pipe be a peach shape, non-just round; Have the high temperature spark to fly out when (2) welding, the weld bond lip temperature is also higher, generally more than 550 ℃, so will amplify the gap of aluminum pipe internal diameter and cable core, in order to avoid scald cable core, causes product quality defect.Therefore, in the technology in early days, as long as welding does not have defective, shape requirement is not high., along with the raising of aluminum-sheathed cable pressurize airtight performance, bigger variation has taken place in corresponding technology.Present technology is to apply PUR in aluminum tube surfaces, is used for leakproof and anticorrosion, but coating is very thin, have only below 0.1 millimeter, thus very rounding of aluminum pipe cross sectional shape required, and ratio-frequency welding welds not rounding of aluminum pipe, cable core and aluminum pipe excesssive gap, the subsequent handling waste of material is also bigger.So need design online tube reducing apparatus for shaping.
Summary of the invention
The utility model is exactly for solving aluminum pipe when the pressurizing unit moulding in preceding road is welded, need the clamping of road, back tube reducing device, prevent the upset of aluminum pipe, being beneficial to the aluminum pipe extrusion modling; Eliminate the wedge angle or the burr projection at weld seam position simultaneously, reduce the gap between cable core and the aluminum pipe, make aluminum tube surfaces rounding, smooth.For reaching this goal of the invention, the utility model adopts following structure: a kind of high-frequency welding aluminium sheath tube reducing device, comprise support and tube reducing wheel, be fixed with horizontal stand on the main support, fixedly connected fixedly tube reducing wheel on the horizontal stand, the sliding support that is installed with slip tube reducing wheel is connected by adjustment screw with horizontal stand, be fixed on and adjustment screw also is installed on the vertical support frame on the main support is connected with sliding support, can realize Position Control by changing adjustment screw to sliding support, thereby change the horizontal and vertical extruding force of slip tube reducing wheel, the set screw that is used for changing the sliding support lateral attitude is installed in the side of fixed press wheel, and the set screw that is used for changing the sliding support lengthwise position is installed in the top of vertical support frame.Rotate the adjustment screw of each support during the utility model work, make the sliding support that has the tube reducing wheel in level and the vertical support frame act on non-circular aluminum pipe at the certain pressure of vertical and horizontal generation, aluminum pipe is out of shape at vertical and horizontal, reach the purpose that reduces the aluminum pipe external diameter, the aluminum pipe external diameter can reduce 0.5mm～1.0mm simultaneously, improves the aluminum pipe roundness.Advantage of the present utility model is: more be not subjected to the influence of speed with drawing reducing process device, resistance is little, compact conformation, and tube reducing shaping amount is big, and it is convenient and swift that specification is changed in operation, and production efficiency is high.

Embodiment
Below in conjunction with example the present invention is specifically described: be fixed with horizontal stand 2 on the main support 1, fixedly connected fixedly tube reducing wheel 3 on the horizontal stand, the sliding support 7 that is installed with slip tube reducing wheel 6 is connected by adjustment screw 4 with horizontal stand, be fixed on and on the vertical support frame 5 on the main support adjustment screw be installed also and be connected with sliding support, can realize Position Control by changing adjustment screw, thereby change the horizontal and vertical extruding force of slip tube reducing wheel sliding support.The set screw that is used for changing the sliding support lateral attitude is installed in the side of fixed press wheel, and the set screw that is used for changing the sliding support lengthwise position is installed in the top of vertical support frame.During the work of this device, rotate the adjustment screw of each support, make the sliding support that has the tube reducing wheel in level and the vertical support frame act on non-circular aluminum pipe, aluminum pipe is out of shape at vertical and horizontal, reach the purpose that reduces the aluminum pipe external diameter at the certain pressure of vertical and horizontal generation.
