Abstract

The utility model discloses an aluminum sheath-shaping device, which comprises a supporting plate, three groups of vertical rollers, two groups of horizontal wheels, fixed pole supports and cantilevered floating pole supports; wherein, the supporting plate is mounted on angle-adjusting steadiers; the fixed pole supports and the cantilevered floating pole supports are mounted on the supporting plate; each group of vertical rollers include a fixed shaping roller and a floating shaping roller; the fixed shaping rollers are fixed on the fixed pole supports; the floating shaping rollers are fixed on the cantilevered floating pole supports; each group of horizontal wheels include two rolling wheels which are arranged transversely and horizontally; and an aluminum band is formed after orderly passing the three groups of vertical rollers and the two groups of horizontal wheels. An aluminum sheath produced by the aluminum sheath-shaping device can be uniformly deformed and stably shaped, and moreover, in the process of shaping the aluminum band, the rolling wheels can be automatically adjusted and aligned, so that the replacement and adjustment of the tooling are simple and convenient.

Description

A kind of aluminium sheath shaped device

Technical field

The utility model relates to electric wire manufacturing equipment field, particularly about a kind of aluminium sheath shaped device that utilizes the high-frequency welding technology to make and use in the aluminum-sheathed cable process.

Background technology

Utilize the high-frequency welding technology to make one of key production technology thereof of aluminum-sheathed cable, it is exactly the aluminium sheath moulding process, the aluminium sheet band that it will cut in advance passes through shaped device, through the serial format roll roll extrusion of installing in the shaped device aluminium strip is rolled into the aluminum pipe shape, the conventional aluminum pipe forming apparatus adopts one group to be fixed into forming roll aluminium strip is carried out the roll extrusion straight forming one time, therefore causes the circumferential edges of aluminum pipe moulding rough, continuous; And adopt and be fixed into forming roll, can make adjusting, centering, replacing more complicated in the aluminium strip forming process.The utility model is exactly for obtaining being suitable for the aluminum pipe shape of cable core in the aluminium strip forming process, specialized designs a kind ofly have shaped devices of forming forming rolls more, format roll adopts the float type structure to overcome the ineffective activity of conventional fixed format roll, and aluminium strip is through the aluminium sheath shape that repeatedly progressively forms behind the curly course of format roll rounding relatively.

Summary of the invention

The purpose of this utility model just provides a kind of aluminium strip distortion, reasonable in design, simple in structure, easy to operate aluminium strip shaped device of moulding of making, adopts following structure to realize for reaching this purpose:

A kind of aluminium sheath shaped device, comprise supporting bracket, three groups of vertical rollses, two groups of horizontal wheels, fixing pole and the cantilever pole of floating, supporting bracket is installed on the angle adjustment support, fixedly the unsteady pole of pole and cantilever is installed on the supporting bracket, every group of vertical rolls is fixed into forming roll by one and a unsteady format roll is formed, being fixed into forming roll is fixed on fixedly on the pole, the unsteady pole of cantilever is gone up the fixing format roll that floats, every group of horizontal wheels comprises the rolling wheel that two transverse horizontal are arranged, and aluminium strip is successively by three groups of vertical rollses and two groups of horizontal wheels aftershapings, and the unsteady pole of cantilever that is installed on the supporting bracket is the cantilever beam type structure, can regulate automatically in the aluminium strip forming process, centering, format roll are adopted for reducing friction and can extraordinary nylon nonmetallic materials be made.During the utility model work, aluminium strip by three groups of vertical forming rollers, is badly deformed aluminium strip edge and bottom under the drive of hauling machine gradually, has through formation top after the roll extrusion of the upright wheel of two groups of levels at last to meet the aluminum pipe that welds opening.

Adopt the utility model structure to have the following advantages:

(1) format roll three groups of vertical rollses of employing and horizontal roller are two groups, promptly adopt the edge method of forming to adopt the circumference method of forming more earlier, and it is the comprehensive of two kinds of forming methods, and distortion is even, stable molding.

(2) shaped device is the passive form that hauling machine drives, and has shortened the moulding distance on the basis of stable molding.

(3) format roll be supported for cantilever beam structure, last format roll is designed to floatability, can regulate automatically in the aluminium strip forming process, centering, makes frock change to adjust simple, convenient.

(3) format roll adopts extraordinary nylon nonmetallic materials, has self-lubricating property, wheel be with between coefficient of friction little, solved metal material and aluminium bonding after, make aluminium strip moulding problem of unstable.

(4) aluminium strip distortion internal stress is little, and the aluminium sheath shape that obtains is rounding relatively.

Embodiment

Below in conjunction with example the present invention is specifically described: supporting bracket 1 is housed on the angle adjustment support 4, the unsteady pole 2 of adjustable cantilever is housed on the supporting bracket, fixedly pole 6, on cantilever floats pole, the format roll 3 that floats is installed, fixedly install and fix format roll 7 on the pole, three groups of vertical rolls sequence arrangement are fixed on two groups of horizontal wheels on the supporting bracket after 5 vertical rollses; During work, cable core and straight aluminium strip enter in the progressive up format roll pressure device of climbing under the drive of hauling machine simultaneously, and first group of vertical rolls finished the moulding of aluminium strip marginal portion, as Fig. 3; Second group of vertical forming roller makes the undeformed aluminium strip of upper track middle part produce circular arc, as Fig. 4; The 3rd group of vertical forming roller makes the aggravation of deformation circular arc position, is beneficial to moulding, as Fig. 5, after the aluminum pipe behind the first one-step forming passes through horizontal wheels 5 roll extrusion again, becomes the circle that is similar to big opening, as Fig. 6; Last group horizontal wheels roll extrusion aluminum pipe makes its openings of sizes meet the high-frequency welding requirement of corresponding specification aluminum pipe, promptly meets the requirement of last extrusion modling.
