Background technology:
The angle of wire rope sling from making, it is the deep processed product of steel rope.Generally speaking, it is the two ends at steel cable, forms the collar by steel rope and also forms with claim-reduction is fixed.Traditional claim-reduction is fixed to be mainly manual the volume and to insert processing, and this volume is plugged in hoist cable, and not only consolidation strength is low, service life short, and compiles and insert the position chain mark and easily prick the hand, be stained with foul, very dangerous.In recent years, the domestic fixed hoist cable that has begun to adopt squeezing bushing had promptly replaced compiling slotting claim-reduction with the stamped metal joint.The fixed hoist cable of this extruding is novel structure, good looking appearance, easy to use not only, and consolidation strength is plugged in hoist cable height, long service life more than compiling.At present, pushing fixed hoist cable does not still have one of reason of wide popularization and application at home, is the metal tube and the compacting tool set existing problems of the fixed usefulness of extruding, the joint consolidation strength out of reach designing requirement after the compacting.CN2377236Y has announced a kind of " wire sling ", is exactly at above-mentioned shortcoming, in order to increase the intensity and the safety of extruding hoist cable, compiles on the basis of inserting manual, carries out the aluminium hoop again and withholds (being the aluminum pipe extruding) processing.In other words, worry exactly aluminum pipe intensity low, particularly with seam aluminum pipe pressure-formed hoist cable poor reliability is arranged, and a kind of job operation of inserting of compiling of taking with the combination of aluminium hoop.This compound type hoist cable, complex manufacturing technology, the steel rope consumption is big, the cost height.
The utility model content:
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of wire rope sling and compacting tool set thereof are provided, and it is reasonable that it has mold design, swagelok is selected for use correctly, and manufacture craft is simple, the consolidation strength height of hoist cable, advantages such as the steel rope consumption is little, and cost of product is low.Solved and pushed the security hidden trouble that fixed hoist cable exists, given up the doubt of people, thereby made the advanced fixed hoist cable of extruding to be more widely used its reliability.
The purpose of this utility model is achieved in that
A kind of wire rope sling, the collar that is formed by steel rope and the claim-reduction of the fixed collar are formed, and its described claim-reduction is the pressure-formed joint of the circular seamless metal pipe of a kind of usefulness.
Described claim-reduction can be with the pressure-formed joint of the circular pipe of aluminum alloy.
Described claim-reduction can also be with the pressure-formed joint of high-quality low-carbon (LC) solid drawn pipe.
A kind of compacting tool set of wire rope sling, form by the die cavity that upper die and lower die and upper and lower mould closure constitute, its die cavity is the external diameter design according to claim-reduction, die cavity is provided with cutting edge outward, be provided with spacing plane between the upper die and lower die, it is characterized in that described mould under closure state, its die cavity is slightly little than the external diameter of claim-reduction along the short transverse of mould.
The bit plane of can not limiting between the described upper die and lower die leaves bigger die slot.
Be provided with the spigot surface of cooperation between the described upper die and lower die.
Two semicircle die cavitys of described upper die and lower die on its Joint face of a pattern, can be made toroidal.
Prior art the fixed hoist cable of extruding, be to suppress joint with a kind of flat ellipse aluminium-alloy pipe because this flat oval tube exists the manufacturability slit in metallurgical crumpling process, use its to come pressure-formed hoist cable joint to dissect after, can find longitudinal crack, therefore exist potential safety hazard.The utility model selects for use round metal tube to suppress claim-reduction, because the circular aluminium-alloy pipe of metallurgical extruding is a seamless tube, so, safe and reliable with the pressure-formed joint of this circular aluminum pipe.If suppress joint with the high-quality low carbon steel pipe, its intensity height, the better reliability of hoist cable.
The compacting tool set of traditional wire rope sling, die cavity are the external diameter designs according to claim-reduction, are provided with spacing plane between the upper die and lower die, when exerting pressure, as long as the spacing plane of upper and lower mould contacts and will stop, so be called " spacing method " pressing mold.
Because the steel cord structure specification is various, the identical and structure of nominal diameter, the steel rope that the wire rope core material is different have different cross section metal plumpness (ratio of the long-pending area with the nominal diameter circumscribing circle of cross section metal), and what have differs from one times.Therefore, press steel rope nominal diameter design-calculated mould series, a mold can not guarantee to compress the steel rope with diameter different cross section metal plumpness.That is to say that a mold just can extrude different joint external diameters, if impose the diameter of extrusion the same, many having compressed of cross section metal then can occur with same aluminium cover, what the cross section metal was few does not just press tightly, and Here it is causes the technological reason of joint fails.The utility model has proposed a kind of method of controlling modest pressure in order to solve above-mentioned crimping Problem of Failure, is called " limit force method " pressing mold.It is a purpose to compress, and has relaxed other secondary causes, and general upper and lower mould does not contact during compacting, is pressed onto till the given gross pressure, and at this moment, the sleeve pipe metal has filled up the slit of steel rope equably, and sleeve pipe and steel rope are combined closely, and joint is just fastening.Such as: under the situation that is provided with spacing plane between the upper die and lower die, can design slightly than the external diameter of claim-reduction smallerly along the short transverse of mould die cavity, correspondingly change spacing plane simultaneously, reserve suitable die slot; Or spacing plane removed, stay the die slot of broad.The die slot of mold design broad is to get off to regulate drafts for the prerequisite that guarantees gross pressure, to satisfy the steel rope that a cover die prodigiosin compresses different cross section metal plumpness.
Gross pressure during compacting can calculate according to formula: P=(1.5-2.5) à LB, and in the formula: à is the yield strength of shell material, and L is the mean length of compacting back joint, and B is the width average of compacting back joint.
In sum, the utility model has compared with prior art correctly been selected the joint metal sleeve for use, has reasonably designed limit force method pressing mold, thoroughly solved and pushed the security hidden trouble that fixed hoist cable exists, made the advanced fixed hoist cable of extruding to be more widely used.Advantages such as simultaneously, it is simple that the utility model also has manufacture craft, and the steel rope consumption is little, and cost of product is low.
