Abstract
The utility model discloses an aluminum sheath extrusion device, which comprises a bracket, an extrusion wheel, a claw frame, a sliding block and a guide groove. The guide groove is fixed on the bracket; a side plate is fixed on the guide groove and supports a rotating leading screw; the sliding block is connected with the leading screw through rotating threads and can slide in the guide groove; the copper claw frame is fixed on the sliding block; the extrusion wheel is fixed on the claw frame by a shaft pin; a locking nut can be arranged on the rotating leading screw to fix the position of the rotating leading screw after the rotating leading screw is adjusted; and the leading screw can be coated by a sheath and only the ends are exposed for regulation. When the structural design is used and the aluminum pipe is welded online, the extrusion force from the extrusion wheel can be conveniently regulated through adjusting the left rotating leading screw and the right rotating leading screw. And the leading screw has the self locking function, so that the extrusion force can be maintained stably in the large scale production of the aluminum sheath, which ensures the welding quality of the aluminum pipe.
Description
Technical field
The utility model relates to electric wire manufacturing equipment field, particularly a kind of aluminium overcoat pressurizing unit that uses in making high-frequency welding aluminum-sheathed cable process.
Background technology
One of key production technology thereof of high-frequency welding aluminum-sheathed cable, it is exactly the extrusion process of aluminium sheath, it mainly is to give certain extruding force and bonding forming with the not joint close aluminum pipe that prefabricated distortion is good in shaped device, become the good aluminum pipe of seal, the extrusion process device of therefore necessary particular design special use.
The welding of ratio-frequency welding aluminium sheath is to adopt contactless induction welding, the heating of aluminium strip edge is the cooperation that utilizes the kelvin effect and the proximity effect of high frequency induction current, this mode is that the pipe edge of forming promptly is heated to half melting state (550 ℃～580 ℃) in leading to the way of intersection point, lintel just in time takes place in the position that edge metal was dissolved before intersection point, electric current is in this high concentration, make lintel place deposite metal generation partial vaporization, strong spark splash takes place, remove oxide layer, and inner aluminium just reaches half melting state, do not have certain external force, just can't bonding crystallization more together.Therefore, pressurizing unit is just given the good certain extruding force of not joint close aluminum pipe of prefabricated distortion herein, the extruding of band edge mouth is bonded together reach the purpose of seam, the about 2～3Kg/mm of the extruding force that provides usually

Summary of the invention
The purpose of this utility model just provides and a kind ofly gives the device of certain extruding force to the good not joint close aluminum pipe of prefabricated distortion, makes its distortion evenly, reaches the purpose of high-frequency welding, adopts following structure to realize for reaching this purpose:
A kind of aluminium sheath pressurizing unit comprises support, squeegee roller, sheep horn shelf, slide block, gathering sill are fixed on the support, side plate is fixed on the gathering sill and supports and revolves leading screw, slide block is threaded with rotation with revolving leading screw, can slide in gathering sill, is fixed with the copper sheep horn shelf on the slide block, take turns with the pivot pin fixed press on the sheep horn shelf, a locking nut can be installed revolving on the leading screw, fixedly to revolve the adjusted position of leading screw, leading screw can only expose the end with a sheath parcel to be convenient to adjust.During work, aluminium strip is in shaped device, behind multiple tracks moulding compression roller distortion in rolling, the form of aluminium strip prefabricated distortion becoming Fig. 4 enters induction coil, see Fig. 6, induction coil produces alternating magnetic fields under the effect of high-frequency induction welder power supply, and aluminium strip induces the electric current of corresponding frequencies in magnetic field, because the effect of electric current proximity effect, circulation is intensive mobile along the aluminium strip edge in the moulding trigonum, and aluminium strip edge, moulding trigonum is heated to molten condition rapidly; Rotate simultaneously and revolve leading screw, adjust the slide position, make squeegee roller provide suitable pressure in the aluminium strip both sides and act on aluminium strip seam weld, thereby make the combination of aluminium strip edge contact area molecule, form metallic crystal, finish the welding of aluminum pipe, be shaped to the shape of Fig. 5.Utilize structural design of the present utility model, during the online welding of aluminum pipe, the extruding force that squeegee roller provides, can provide convenient the adjusting by regulating left-right turning screw rod, and revolve leading screw and have auto-lock function, make extruding force in the length of aluminium sheath is produced, keep stable, thereby guarantee the welding quality of aluminum pipe.
